Step-by-step explanation:
y = 4 when x = 8 So, 4 = 8k
k = 1/2
y = (1/2)x
Therefore, when x = 10, y = (1/2)(10) = 5
Answer: A) 5/2
B) 10pi for A and 4pi for B
C) 5/2
Step-by-step explanation:

Answer:
cheese 123
Step-by-step explanation: i am sorry i need points
F(x) = x^2 -8x -9
x = -b/2a = 8/2 =4
y = 4^2 -8*4 -9 = 16 -32 -9 = 16 -41 = -25
so the wertex of this function will be (4,-25)
