Answer:

$y = 4*x+3$

Step-by-step explanation:

First pick any 2 set of points to find the slope. I chose (1,7) and (3,15)

The slope formula is shown below

$m = \frac{y_{2} - y_{1} }{x_{2} - x_{1} }$

Now fill in the variables and solve

15 - 3 = 12

3 - 0 = 3

Divide

$12/3 = 4$

So the slope is 4

The y intercept is 3 since that is where x = 0

Now we can write the equation

$y = 4*x+3$

John is joining a gym. There is a membership fee of $25 per month and a fee of $2 per workout class he attends. Given this infor

skad [1K]

Answer:

Input variable x: Number of classes he attends.

Output variable y: Monthly cost

Slope: Cost per class, of $2

y-intercept: Membership fee, of $25.

Function: $y = 2x + 25$

Step-by-step explanation:

This situation can be represented by a function is the following format:

$y = mx + b$

In which y is the monthly cost(output), m is the cost per class(slope), x is the number of classes he attends(input) and b is the membership fee(y-intercept).

We have that:

There is a membership fee of $25 per month and a fee of $2 per workout class he attends.

This means that $b = 25, m = 2$ . So

$y = 2x + 25$

A regular pentagon ABCDE is shown <br><br><br> Work out the size of X

nikdorinn [45]

The sum of the angles in a pentagon is 540°.

This means that each angle is 108°.

Inside you pentagon, a triangle is drawn. This triangle is isosceles, because the corners are on the points of the regular pentagon. You know that angle C is 108°.

Angles in a triangle add up to 180°.

B and D will be the same size as this is isosceles.

180°-108° = 72°

This is B and D. You only need one of these, so you divide by 2.

The answer is 36°.

Hope this helps :)

Answer:

If you center the series at x=1

$T_3(x) = e^2 + 4e^2 (x-1)+10(x-1)^2 + \frac{56}{3} e^2(x-1)^3 + R(x)$
