When we start to solve a physics exercise, we get the exercise data:

Initial Speed = 3.8m/s

Acceleration (a)= 3.7 m/s²

Time (t) = 3 sec.

He tells us that Carter treats at a speed of 3.8 m/s, this is the speed, since he asks us, at what speed does he treat now. Then we must calculate the final speed.

The formula to calculate the final velocity is:

The value of x is 52.5981

The given equation is:

In(x + 2) = 4

Taking log on the right hand side of the equation, we get

x + 2 = [tex]e^{4}[/tex]

The value of [tex]e^{4}[/tex] is 54.59815

⇒ x + 2 = 54.59815

Subtract 2 on both the sides of the equation

⇒ x = 54.59815 - 2

⇒ x = 52.59815

Rounding 52.59815 to 4 places, we get

⇒ x = 52.5981

there are 4 properties we can use to prove if it is a parallelogram, in which 3 of them involve seeing if the sides are parallel or congruent, however for those we must know the value for the angles or sides, the other property is to prove that the diagonals bisect each other.

To prove the diagonals bisect each other is to see if the point of crossing divides into equal parts.

in this case since the division of the points gives the same values for both diagonals we can say that ABCD because the diagonals bisect each other.

Think of -8.8 as -8.80

We're comparing -8.85 to -8.80, which means we're comparing the stuff after the decimal 85 and 80

Since 85 > 80, this places -8.85 to the left of -8.80

It's like saying how -85 is to the left of -80

I recommend drawing out a number line to see what's going on.

The slope of the linear equation that passes through the points (9,1) and (10,−1) is -2.

For a linear equation that goes through two points (x₁, y₁) and (x₂, y₂), the slope is given by the formula:

slope = (y₂ - y₁)/(x₂ - x₁)

In this case, we know that our line goes through the points (9,1) and (10, −1), so we can use these two values in the equation for the line, we will get:

slope = (-1 - 1)/(10 - 9) = -2/1 = -2

So the slope of the linear equation is -2.

The binomial formula with the given parameters has a value of 0.0272

The given parameters are

N = 65

p = 0.5

X = 39

The interpretation of the above parameters are

Sample size, N = 65

Probability of success, p = 0.5

Number of success, X = 39

The binomial probability states that

P(x) = ⁿCₓ * pˣ * (1 - p)ⁿ⁻ˣ

Where n, p and x are the same as the parameters described above

When the values are substituted in the binomial probability formula, we have

P(39) = ⁶⁵C₃₉ * (0.5)³⁹ * (1 - 0.5)⁶⁵⁻³⁹

Evaluate the difference

P(39) = ⁶⁵C₃₉ * (0.5)³⁹ * (0.5)²⁶

Evaluate the products

P(39) = ⁶⁵C₃₉ * (0.5)⁶⁵

Variable x would be easier to solve for.

Step - by - Step Explanation

What to find?

• The value of x.

• The value of y.

• The variable that was easier to solve.

Given:

5x+3y=22

4x-2y=16

Using elimination method,

First solve for x.

To solve for x, multiply through the first equation by 2 and then multiply through the second equation by 3.

10x + 6y = 44 _____________(3)

12x - 6y = 48 ______________(4)

Add (3) and (4)

22x = 92

Divide both-side of the equation by 22

x = 92/22

Reduce the fraction by 2.

x =46 / 11

To solve for y,

Multiply through the first equation by 4 and through the second equation by 5.

20x + 12y = 88 _________________ (5)

20x - 10y = 80 __________________(6)

Subtract equation 6 from 5.

22y= 8

Divide both-side of the equation by 22.

y = 8/22

We can reduce the fraction by 2.

y = 4 / 11

Judging from the steps above, we can deduce that the variable that was easier to solve is x.

Congruent polygons are those that have equal measurements. Since we are given their graphs, we simply inspect each pair of polygons to determine which among them are congruent.

I have made an example using the first pair. I rotated the first polygon (the red one) to show that they are indeed congruent.

Following the same process, we can see that pairs 3 and 4 are also congruent.

Pair 2 are not congruent because the green rectangleis longer.

So the answer is pairs 1, 3, and 4.

[tex]d(f-4)=2(1-f)\\\\frac{d(f-4)}{d} =\frac{2(1-f)}{d} \\f-4=\frac{2(1-f)}{d} \\f=\frac{2(1-f)}{d} +4[/tex]

Answer:

Step-by-step explanation:

d= 2(1-f) / f-4

The total number of lefties present in the class are 125.

For the given question;

The total students in the class are 50.

There are 10 out of 50 on an average students be left-handed.

Let the percentage of left handed be 'x'.

Then, x% of 50 = 10

x = 10×100 / 50

x = 20%.

Now the average number of left-handed students are 25.

The total students will be.

Let 'y' be the total number of students.

Then, 25 is the 20% of y.

20% of y = 25.

y = 25 ×100 / 20

The probability that, in a random sample of 50 customers at Anita's, exactly 3 order their food to go is 0.3240

Probability:

The probability of an event can be calculated by probability formula by simply dividing the favorable number of outcomes by the total number of possible outcomes.

The value of the probability of an event to happen can lie between 0 and 1 because the favorable number of outcomes can never cross the total number of outcomes.

Given,

Anita's, a fast-food chain specializing in hot dogs and garlic fries, keeps track of the proportion of its customers who decide to eat in the restaurant (as opposed to ordering the food "to go"), so it can make decisions regarding the possible construction of in-store play areas, the attendance of its mascot Sammy at the franchise locations, and so on.

Answer: x (y + 1)

By solving both equations we get x =:

1. x = 12

2. x = 28/3

1. |x - 3| = 2x - 15

|x - 3| - 2x = 2x - 15 - 2x

by simplifying,

- 2x + |x - 3| = -15

- 2x + x -3 = -15  and -2x - (x - 3) = -15

by solving equation ,

= -x -3 = - 15

= -x = -12

x = 12

2. 8 - 2|6 - x|= 20

6 |6 - x| = 20

6 |-x + 6| = 20

dividing both side with 6,

             y = a(x - h)² + k  where (h, k) is the vertex.

Given:

f(x) = 4x²

Vertex =  (10,4)

a = 4

The value of a in the vertex form of the equation is taken to be 4 since the coefficients of x² must match for the parabola to have the same shape as the given parabola.

The equation can be written as,

y = a(x - h)² + k  where (h, k) is the vertex.

Replacing the value of the vertex, we get

y = 4(x - 10)² + 4

y = 4(x² - 20x + 100) + 4
