Answer: Everybody will need to pay 3.18 dollars. ($3.18)

Step-by-step explanation:

To find out equal amounts of money, you need to divide the total cost by how many people there are. The total cost, in this case, is 12.72, and the amount of people in this problem is 4 people. That means, if everybody were to pay the same amount, you would need to divide 12.72 by 4.

12.72/4=3.18

Answer:

$y = \frac{1}{8}(x + 4)^2 + 4$

Step-by-step explanation:

Given:

Focus of parabola: (-4, 6)

Directrix: y = 2

Required:

Equation for the parabola

<h2><u>SOLUTION:</u></h2>

Using the formula, $y = \frac{1}{2(b - k)}(x - a)^2 + \frac{1}{2}(b + k)$ , the equation for the parabola can be derived.

Where,

a = -4

b = 6

k = 2

Plug these values into the equation formula

$y = \frac{1}{2(6 - 2)}(x - (-4))^2 + \frac{1}{2}(6 + 2)$

$y = \frac{1}{2(4)}(x + 4)^2 + \frac{1}{2}(8)$

$y = \frac{1}{8}(x + 4)^2 + \frac{8}{2}$

$y = \frac{1}{8}(x + 4)^2 + 4$

consider the function represented by the equation 16b = 4r - 12. write the equation in function notation, where b is the indepen

katovenus [111]

When you write a function in the form $y=f(x)$ , y is the dependent variable, and x is the independent variable.

So, if b is the independent variable, it means that we have to solve the expression for r.

To do so, we perform the following steps: start with

$16b = 4r - 12$

Add 12 to both sides

$16b+12 = 4r$

Divide both sides by 4:

$4b+3 = r$

So, we wrote the expression in the form $r = f(b) = 4b+3$ , which means that r is the dependent variable and b is the independent variable, as requested.
