The van travels over the hill described by y = (-1.5(10-3 ) x2 + 15) ft. If it has a constant speed of 75 ft>s, determine the x and y components of the van’s velocity and acceleration when x = 50 ft.

can you rephrase the question ? it is unclear : -)

step-by-step explanation:

i believe that the answer is

b. y-1=-2(x-4)

hope this !

since we know that the two functions are equal, f (x) = g

(x), therefore when we equate the two equations the result should be similar to

3x = x – 4:

a. f(x) = 3x, g(x) = x – 4

equating the two functions:

3x = x – 4             (correct)

so we now got our answer (a)
