13) let p (x.,y) be a point of the graph of y=x^2-8 a) express the distance d from p to point (0,-1) as a function of x. b) what is d if x 0? c) what is d i#x #-1? d) use a graphing utility to graphd d(a). e) for what values of x is d the smallest?

step-by-step explanation:

i need to answer questions so i dont know but i think its the first one because it goes up but a consent rate

2x=56

step-by-step explanation:

b. 1.25 hr

step-by-step explanation:

if you have a constant speed of 60 mph, then you have a ratio between 60 mi. to 1 hr. dividing both sides by 60 we get the ratio

1 mi. to

then mult. both sides by 75 we get the ratio

75 mi. to

simplifying we get

75 mi. to

or 1.25 hr.
