Answer 1
Answer:

(x + 12)° + (5x)° = 90°

m∠1 = 25° and m∠2 = 65°

Step-by-step explanation:

We know that the little box represents 90 degrees. We will write an equation using this information.

      (x + 12)° + (5x)° = 90°

Next, we will solve by isolating the x variable with inverse operations and combing like terms.

      (x + 12)° + (5x)° = 90°

      x° + 5x° = 78°

      6x° = 78°

      x = 13°

Lastly, we will find the value of each angle by substituting.

       m∠1 = (x + 12)° = ((13) + 12)° = 25°

       m∠2 = (5x)° = (5(13))° = 65°

partners with businesses to provide loans to
consumers for purchasing goods and services

Answers

Consumer lending Partnerships play a crucial role in facilitating economic transactions by bridging the gap between businesses and consumers.

A consumer lending partnership is a collaboration between businesses and financial institutions that aims to provide loans to consumers for purchasing goods and services. This partnership allows businesses to offer their customers convenient financing options, enabling them to make purchases that they might not be able to afford upfront. It benefits both the businesses and consumers by promoting sales and providing access to affordable credit.

In this arrangement, businesses typically partner with banks, credit unions, or other financial institutions that specialize in consumer lending. These lenders evaluate the creditworthiness of consumers and provide loans based on predetermined criteria such as credit scores, income levels, and repayment history. The loans can be structured as personal loans, installment loans, or revolving credit lines, depending on the nature of the purchases and the agreement between the lender and the business.

By partnering with financial institutions, businesses can offer attractive financing options to their customers, which can increase sales and customer loyalty. Consumers benefit from the ability to make purchases and pay them off over time, spreading the cost of expensive items or services into affordable monthly payments. This arrangement expands consumer purchasing power and provides access to necessary or desirable goods and services that may otherwise be out of reach.

In addition to benefiting businesses and consumers, consumer lending partnerships also contribute to the growth of the financial institutions involved. These partnerships create opportunities for lenders to expand their customer base, generate interest income from loan repayments, and establish relationships with businesses in various industries.

Overall, consumer lending partnerships play a crucial role in facilitating economic transactions by bridging the gap between businesses and consumers. They provide a mutually beneficial solution that empowers consumers with access to financing and enables businesses to drive sales and foster customer satisfaction.

Using the sum and difference formula and trigonometric identities the value of tanθ and cosθ are cos(11π/12) = (-√6 + √2) / 4 and tan(11π/12) = 0 respectively.

Determine tanθ using the sum formula

The identity tan(α + β) = (tanα + tanβ) / (1 - tanα * tanβ) may be used to calculate tan using the sum method.

Here, we have θ = 11π/12, so we need to express it as the sum of two angles.

In this problem, we are given θ = 11π/12 and we can use the sum of two angles.

11π/12 = π/6 + 5π/6

putting the value of α = π/6 and β = 5π/6.

The sum formula of the tangent becomes;

tan(11π/12) = tan(α + β) = (tanα + tanβ) / (1 - tanα * tanβ)

Let's put in the values of α and β:

tan(11π/12) = (tan(π/6) + tan(5π/6)) / (1 - tan(π/6) * tan(5π/6))

The tangent of π/6 and 5π/6 will have values as;

tan(π/6) = √3/3

tan(5π/6) = -√3/3

Let's put in these values into the sum formula;

tan(11π/12) = (√3/3 + (-√3/3)) / (1 - (√3/3 * (-√3/3)))

tan(11π/12) = 0 / (1 - (-3/9))

= 0 / (1 + 1/3)

= 0 / (4/3)

= 0

Therefore, tan(11π/12) = 0.

Part B;

Using difference formula, the value of cosθ can be expressed using the trigonometric identity

cos(α - β) = cosα * cosβ + sinα * sinβ

Since we are given θ = 11π/12;

Let's express this as the difference of two angles

11π/12 = 3π/4 - π/6

Putting the value α = 3π/4 and β = π/6.

Using the difference formula for cosine;

cos(11π/12) = cos(α - β) = cosα * cosβ + sinα * sinβ

Let's plug in the values of α and β

cos(11π/12) = cos(3π/4 - π/6) = cos(3π/4) * cos(π/6) + sin(3π/4) * sin(π/6)

The known values of cosine and sine for 3π/4 and π/6 are;

cos(3π/4) = -√2/2

cos(π/6) = √3/2

sin(3π/4) = √2/2

sin(π/6) = 1/2

Plugging these values into the difference formula;

cos(11π/12) = (-√2/2 * √3/2) + (√2/2 * 1/2)

cos(11π/12) = -√6/4 + √2/4

Combining like terms:

cos(11π/12) = (-√6 + √2) / 4

Therefore, cos(11π/12) = (-√6 + √2) / 4.

In a normal distribution of 1027 values, the mean is 75 and the standard deviation is 8. What is the closest number of values that would be above 91?

A) 26

B) 2567

C) 976

D) 51

Answers

Answer: 26

Step-by-step explanation:

The closest number of values above 91 is 23.

We have,

To find the closest number of values that would be above 91 in a normal distribution with a mean of 75 and a standard deviation of 8, we need to calculate the z-score for the value 91 and then find the proportion of values above that z-score.

The formula for calculating the z-score is:

z = (x - mean) / standard deviation

where x is the value of interest, the mean is the mean of the distribution, and the standard deviation is the standard deviation of the distribution.

In this case,

x = 91, mean = 75, and standard deviation = 8.

Plugging these values into the formula, we get:

z = (91 - 75) / 8 = 2

To find the proportion of values above a z-score of 2, we can refer to the z-table or use a calculator that provides the cumulative distribution function (CDF) for the standard normal distribution.

Looking up the z-score of 2 in the z-table or using a calculator, we find that the proportion of values above a z-score of 2 is approximately 0.0228.

To determine the number of values above 91 in a distribution of 1027 values, we multiply the proportion above 91 (0.0228) by the total number of values (1027):

Number of values above 91 = 0.0228 x 1027 ≈ 23.47

Since we are looking for the closest whole number, the closest number of values above 91 would be 23.

Therefore,

The closest number of values above 91 is 23.

Step-by-step explanation:

The critical points of a function are the points where the derivative of the function is either zero or undefined.

We can find the derivative of the given function using the product rule.

[tex]\boxed{\begin{minipage}{5.5 cm}\underline{Product Rule for Differentiation}\\\\If $y=uv$ then:\\\\$\dfrac{\text{d}y}{\text{d}x}=u\dfrac{\text{d}v}{\text{d}x}+v\dfrac{\text{d}u}{\text{d}x}$\\\end{minipage}}[/tex]

Given function:

[tex]\textsf{Let}\; u=2x+1 \implies \dfrac{\text{d}u}{\text{d}x}=2[/tex]

[tex]\textsf{Let}\; v=e^x \implies \dfrac{\text{d}v}{\text{d}x}=e^x[/tex]

Apply the product rule:

[tex]\begin{aligned}f'(x)&=(2x+1)e^x+e^x(2)\\&=(2x+1)e^x+2e^x\\&=e^x(2x+1+2)\\&=e^x(2x+3)\end{aligned}[/tex]

Set the derivative equal to zero and solve for x:

[tex]\begin{aligned}f'(x)&=0\\e^x(2x+3)&=0\\2x+3&=0\\2x&=-3\\x&=-\dfrac{3}{2}\end{aligned}[/tex]

Therefore, the critical point of the function f(x) is when x = -3/2.

|x-5| if x<5

Please help!

Answers

when x < 5, we can simplify it as -(x - 5) because (x - 5) is negative.

We have,

Absolute value:

The absolute value of a number represents its distance from zero on the number line. It is always a non-negative value.

For example, the absolute value of 3 is 3, and the absolute value of -3 is also 3.

|x - 5|:

In this expression, we have the absolute value of the quantity (x - 5).

It means that we are looking at the distance between x and 5 on the number line.

x < 5:

The condition x < 5 states that x is less than 5.

It means that x is located to the left of 5 on the number line.

Simplification:

When x is less than 5, it implies that x is located to the left of 5.

In this case,

The quantity (x - 5) becomes negative because we are subtracting a larger value (5) from a smaller value (x).

Now,

The expression |x - 5| can be simplified to -(x - 5), which means taking the negation of (x - 5).

- If x = 3, which is less than 5, we can substitute it into the expression:

|x - 5| = |3 - 5| = |-2| = 2

- If x = 7, which is greater than 5:

|x - 5| = |7 - 5| = |2| = 2

In both cases,

The value of |x - 5| is 2.

However, when x < 5, we can simplify it as -(x - 5) because (x - 5) is negative.

Thus,

when x < 5, we can simplify it as -(x - 5) because (x - 5) is negative.

The values of x and y that maximize the total revenue are approximately 3600 units of A and 3200 units of B.

We are given that;

Function R(x,y)=-5x2-8y2-2xy + 42x+102y

To maximize the total revenue from x units of A and y units of B, we need to find the values of x and y that maximize the function R(x,y)=-5x2-8y2-2xy + 42x+102y. This is an optimization problem with two variables.

To solve this problem, we need to find the critical points of R(x,y) by taking partial derivatives with respect to x and y and setting them equal to zero.

R_x = -10x - 2y + 42 = 0

R_y = -16y - 2x + 102 = 0

The slope of a line is positive with a value of 3/2 or 1.5.

What is the slope of the line?

The slope of the line is the ratio of the rise to the run, or rise divided by the run.

The slope of a line is used to describe the steepness and direction of the line.

Mathematically, the formula for the slope of a line is given as;

slope = Δy / Δx

where;

Δy is the change in the y valuesΔx is the change in x values

The slope equation is expanded as follows;

m = ( y₂ - y₁ ) / ( x₂ - x₁ )

From the graph, the values of x and y is determined as;

( x₁, y₁ ) = ( - 2, 0 )

( x₂, y₂) = ( 0, 3 )

The slope of the line is calculated as follows;

m = ( y₂ - y₁ ) / ( x₂ - x₁ )

m = ( 3 - 0 ) / ( 0 - - 2)

m = 3 / 2

color blindness occurs in 4% of the male population. design a simulation that can be used to estimate the probablitiy that a randomly chose male will be color blind

Answers

To design a simulation to estimate the probability that a randomly chosen male will be color blind, you can follow these steps:

Set up the simulation: Determine the number of males to include in your simulation. Let's say you choose to simulate 10,000 males.

Generate random color blindness: Use a random number generator to assign color blindness status to each simulated male. Since color blindness occurs in 4% of the male population, you can randomly assign color blindness to approximately 4% of the males in your simulation.

Count the number of color-blind males: Iterate through the simulated males and count the number of males who are color blind.

Calculate the probability: Divide the count of color-blind males by the total number of males in the simulation to obtain the estimated probability. Multiply the result by 100 to express it as a percentage.

Here's a Python code snippet to illustrate this simulation:

import random

num_simulated_males = 10000

num_color_blind_males = 0

for _ in range(num_simulated_males):

   if random.random() <= 0.04:  # Probability of being color blind

       num_color_blind_males += 1

probability_color_blind = (num_color_blind_males / num_simulated_males) * 100

print(f"Estimated probability of a randomly chosen male being color blind: {probability_color_blind:.2f}%")

Keep in mind that this simulation provides an estimate based on the assumed probability of 4% for color blindness in the male population. The actual probability may vary slightly, but running the simulation with a large number of simulated males should yield a reasonably accurate estimate.

Answers

Answer:

a) The time taken for the ball to reach John is: 10/x seconds.

b) The time taken for the ball to go from John to Pierre is: 15/(x - 0.5) seconds.

c) The equation that shows the total time taken from Ahmed to Pierre simplifies to 2x^2 - 9x - 2 = 0.

Step-by-step explanation:

a) The time taken for the ball to reach John can be calculated using the formula:

time = distance / speed

Since the distance traveled by the ball is 10m and the speed is x m/s, the time taken can be expressed as:

time = 10 / x seconds

b) The time taken for the ball to go from John to Pierre can be expressed as:

time = distance / speed

Since the distance traveled by the ball is 15m and the speed is 0.5 m/s less than the speed at which the ball traveled from Ahmed to John (i.e. x - 0.5 m/s), the time taken can be expressed as:

time = 15 / (x - 0.5) seconds

c) Let's use the information given to write an equation for the total time taken from Ahmed to Pierre. We know that the time taken for the ball to travel from Ahmed to John is 10/x seconds, the time taken for the ball to travel from John to Pierre is 15/(x-0.5) seconds, and the time taken between John catching the ball and throwing it to Pierre is 2 seconds. Therefore, the total time taken can be expressed as:

10/x + 15/(x-0.5) + 2 = 7

Multiplying both sides by x(x-0.5) to get rid of the denominators, we get:

10(x-0.5) + 15x + 2x(x-0.5) = 7x(x-0.5)

Simplifying and rearranging, we get:

2x^2 - 9x - 2 = 0

Therefore, the equation simplifies to 2x^2 - 9x - 2 = 0.

Explain the difference between an indefinite integral and a definite integral.
A) An indefinite​ integral, after evaluating it at the limits of​ integration, results in a particular number. A definite integral results in a set of functions that share the same derivative and uses an arbitrary constant of integration.
B) A definite​ integral, after evaluating it at the limits of​ integration, results in a particular number. An indefinite integral results in a set of functions that share the same derivative and uses an arbitrary constant of integration.
C) An indefinte integral cannot always be integrated analytically and may require numeric​ integration, while it is always possible to integrate a definite integral. Definite integrals always return a real number after evaluation at its limits of integration.
D) A definite integral is defined and continuous over the interval of integration and has finite limits of integration. An indefinite integral is also defined and continuous over the interval of​ integration, but may have as a limit of integration.

Answers

The answer is A.

An indefinite integral is a function that, when differentiated, equals the original function. It is denoted by ∫f(x)dx, where f(x) is the function to be integrated. An indefinite integral always has an arbitrary constant of integration, which is denoted by C. This is because the derivative of any constant is zero, so the derivative of ∫f(x)dx+C is still equal to f(x).

A definite integral is the limit of a Riemann sum as the number of terms tends to infinity. It is denoted by ∫

a

b

f(x)dx, where a and b are the limits of integration. A definite integral does not have an arbitrary constant of integration, because the limits of integration specify a unique value for the integral.

In other words, an indefinite integral is a family of functions that share the same derivative, while a definite integral is a single number.

Carlos has a collection of old vinyl records. To play some of the records, the turntable rotates through an angle of 3/2pi radians in 1 second. How many revolutions does the record make in one minute?
A. 33 1/3 revolutions per minute
B. 45 revolutions per minute
C. 78 revolutions per minute
D. 16 2/3 revolutions per minute

Answers

Step-by-step explanation:

We know that the turntable rotates through an angle of 3/2pi radians in 1 second.

To find the number of revolutions in one minute, we need to convert the angle to revolutions per minute.

There are 2π radians in one revolution, so we can set up a proportion:

(3/2π radians) / (1 second) = (x revolutions) / (1 minute)

To solve for x, we can cross-multiply and simplify:

(3/2π) * (1 minute) = x * (1 second) * (2π)

x = (3/2π) * (60/1)

x = 45 revolutions per minute

Therefore, the answer is B. 45 revolutions per minute.

78.95*0.3

Can someone please show me a step by step of how I would write this out and solve it? (No calculators)

Answers

Answer:

23.685

Step-by-step explanation:

Ok, lets convert them into fractions

78.95=7895/100

0.3=3/10

7895*3/1000

7895*3=21000+2400+270+15=23685

23685/1000=23.685

5. Priest and Sons, is a local manufacturer of a product that sells for $13.50 per unit. Variable costper unit is $7.85 and fixed cost per period is $1 220. Capacity per period is 1100 units. Perform a break-even analysis showing an algebraic statement of:

a. the revenue function

b. the cost function

c. calculate the break-even point in units

Answers

The break-even point is approximately 217 units.

We are given that;

Cost of local product= $13.50

Variable cost per unit= $7.85

Fixed cost per period= $1

Now,

The revenue function is the product of the price per unit and the number of units sold:

R(x)=13.50x

where x is the number of units sold.

The cost function is the sum of the fixed cost and the variable cost per unit multiplied by the number of units sold:

C(x)=1220+7.85x

where x is the number of units sold.

The break-even point is the point at which revenue equals cost. We can find this point by setting R(x) equal to C(x) and solving for x:

13.50x=1220+7.85x

5.65x=1220

x≈216.81

Therefore, by the function the answer will be 217 units.
