Write an equation for the function graphed below?

Given the function of the rate of change of the population:

The integral of this function will be the value of the population growth of the town from 1990 to 2010. This is because P(t) is the rate of change of population, its integral will be the antiderivative, that is the population of the town.

To calculate the change in population we have to find the integral from 5 to 10 of P(t):

The change in population can not be a decimal number, so we can round it to 1162.

To calculate the population in 2020 we have to find the integral from 0 to 30 of P(t) and then add it to 10000 which was the initial population (we already know the integral so we're just going to evaluate it):

It means that the population in 2020 is 18221 (Remember that we round it because it is not possible to have a decimal value for the population of the town).

Answer:

yes

Step-by-step explanation:

if y = -6,

3x = -6

x = -2

Answer:

yes

Step-by-step explanation:

y = 3x?

Let x = -2 and y = -6

-6 = 3(-2)

-6 = -6

This is a true statement so (-2,-6) is a solution to the equation y = 3x

Debbie's checkbook balance is $-3,297.23, which shows an overdraft.

An overdraft occurs when the money (deposits) in Debbie's account does not exceed her payments or withdrawals.

While Debbie had a positive beginning balance, the ending balance shows an overdraft of $-3,297.23.

By this overdraft, Debbie's bank is extending her some short-term credit, which she should pay back with interest.

Beginning balance on checkbook =  $2,715.50

Checks for the month =                     $-5,298.13

Deposits for the month =                       $250.16

Payroll check =                                 $-2,980.66

IRS check =                                          $2,550

Auto insurance and utilities =               $-534.10

Ending balance on checkbook =     $-3,297.23

Thus, Debbie's ending checkbook balance will show an overdraft of $-3,297.23.

Let x be the length of the rectangle and y be the width of the rectangle, then we can set the following equations:

Solving the first equation for x we get:

Substituting x=20-y in the second equation we get:

Now, we will use the first and second derivative criteria to find the maximum.

The first and second derivatives are:

Since the second derivative is a negative number that means that A(y) reaches a maximum when A´(y)=0.

Solving A´(y)=0 for y we get:

Now, substituting y=10 in x=20-y, we get:

The given fraction 60/25 into a mixed number would be 2 2/5 in the lowest terms.

A fraction is defined as a numerical representation of a part of a whole that represents a rational number.

First, we have to find the whole number,

Determine how many times the denominator enters the numerator. Divide 60 by 25 and preserve just the numbers to the left of the decimal point:

⇒ 60 / 25 = 2.4000 = 2

Then, find a new numerator :

Multiply the result by the denominator and subtract it from the original numerator.

⇒ 60 - (25 x 2) = 10

Now, put together

To obtain this, keep the original denominator and use the solutions from Steps 1 and 2:

⇒ 2 10/25 ⇒ 2 2/5

Thus, the given fraction 60/25 into a mixed number would be 2 2/5 in the lowest terms.

Given:

400 lb of coffee is sold at $8 per pound.

To find:

A) List the data points

B) The slope of line joining the points

C) Interpretation of meaning of slope of line

D) linear equation of data using point slope form

E) Using the function we need to predict the number of consumers buying at $6 per pound

Step-by-step solution:

A) Data points of the given data:

Data points:

(4,650) and (8,400)

B) The slope of the line joining the points:

C) Interpretation of meaning of slope of line:

Slope here means that:

When there is an increase in the price of coffee then the weight of coffee decreases.

Weight per dollar of coffee decreases at the rate of 62.5

D) linear equation of data using the point-slope form:

Applying point-slope form:

y - y1 = m(x - x1)

y - 650 = -62.5(x - 4)

y = -62.5x + 900

In function notation it can be represented as:

S(P) = -62.5P + 900

E) Using the function we need to predict the number of consumers buying at $6 per pound

To predict that, we will simply put the value of P equal to 6 in the given function:

S(P) = -62.5P + 900 At P = 6

S(P) = -62.5(6) + 900

S(P) = 525

Thus we can say that 525 customers will buy at $6 per pound.

Given,

The weight of candies normally distributed ;

Mean  weight of candies = 0.8543 g

Standard deviation, σ = 0.0519 g

Sample of candy came from a packet of 469 candies

Net weight of the packet = 400.3 g

Average weight of the candies in the packet;

[tex]x_{avg} =[/tex] ∑xi/n = 400.3/469 = 0.8535

The population standard deviation (sigma=0.0519 g) is the standard deviation for a confectionery that was chosen at random (sample size n=1).

z = (X - μ) / (σ/√n) = (0.8536 - 0.8535) / (0.0519/√1) = 0.0001/0.0519 = 0.002

P(X > 0.8536) = P(z > 0.002) = 0.4992

A randomly chosen candy has a probability P=0.4992 of weighing at least 0.8536 g.

z = (X - μ) / (σ/√n) = (0.8543 - 0.8535) / (0.0519/√441) = 0.0008/0.0024 = 0.3288

P(X > 0.8543) = P(z > 0.3288) = 0.37115

A sample of 441 candies chosen at random has a probability P=0.3712 of having an average weight of at least 0.8543 g.

z = (X - μ) / (σ/√n) = (0.8556 - 0.8535) / (0.0519/√469) = 0.0021/0.0024 = 0.89

P(X > 0.8556) = P(z > 0.89) = 0.18673

Answer:

x and y is 59 degrees

Step-by-step explanation:

You can find the angle next to 121 which is 59 degrees considering linear pair. Then, you can figure out y by doing corresponding angles and so this means that y is also 59 degrees. To find x, we know that x is vertical to y and that they are the same value. So, this means that x is 59 degrees as well. Hope this helps!

Answer:

[tex]w \leq 1.9[/tex]

Step-by-step explanation:

The picture itself measures 6" by 8". Therefore, the area is 6 * 8 = 48 square inches.

All of the pieces of wood have the same width, and we know that two of them will be 6 inches long and two will be 8 inches long.

Therefore, the combined area of the pieces of wood will be 2 * 6w and 2 * 8w. This gives us 12w + 16w.

Now we can set up an inequality:

48 (area of picture) + 12w + 16w <= 100 (maximum area).

Simplify the left side of the equation to give us this:

[tex]48+28w\leq 100.[/tex]

We can move the 48 over to the other side to get [tex]28w \leq 100 - 48[/tex], which simplifies to [tex]28w \leq 56[/tex]. Now, you just have to divide both sides by 28 to get [tex]w\leq 1.857[/tex].

Rounding to the nearest tenth of an inch gives us 1.9 as the maximum width of the pieces of wood.
