Question 37 (1 point) (03.09)
What is the equation of the quadratic graph with a focus of (3, -1) and a directrix
of y = 1? (1 point)
1) f(x) = -1/4 (x - 3)2 + 1 2) f(x) = -1/4 (x - 3)²
3) f(x) = 1/4 (x - 3)²+ 1
4) f(x) = 1/4 (x - 3)²

sorry i just need to anwers this to get points

step-by-step explanation:

constant of proportionality = 3 and the equation is c = 3p.

step-by-step explanation:

c = kp   where c = amount of caffeine in mg., p = oz of pepsi and k is the constant of proportionality.

substituting the values given:

24 = 8k

k = 3.

the same value of k will be obtained if we substitute the other given values.

change of stock price/initial stock price on friday * total stock value = change of stock value

0.89/73.73 *x = 42.72

x=3539.04 = total stock value at initial stock price on friday .

total stock value at initial stock price on friday/ initial stock price on friday = number of shares

3539.04/73.73 = 48 shares

they own 48 shares of this stock
