Answer:
Step-by-step explanation:
Y-0=-4(x-2)
Answer:
v=169
Step-by-step explanation:

Divide by 4.


The height is represented by d.
d = 10 feet

Use quadratic formula:
t = 1.58, -2.02 (reject)
1.58 seconds
You need to tell how many percent you will discount and then find the new price
F(x) = 3(x-4)^2-38 because finding the perfect square would get you f(x)+38=3(x^2-8x+16) and then finding the squareroot of that and moving the constant on the left back to the right would leave u with f(x)=3(x-4)^2-38
