answer: a) (0,0), (1,1), (2,8), and (3,27).
step-by-step explanation:
0^3=0
1^3=1
2^3=8
3^3=27
in effect, the exponential equation for this would me y=3^x. each x-coordinate cubed is giving the y coordinate, so a is your answer : )
the aswere is the one with all 8's and the second one is with the 10,8 and 6
b. 1.25 hr
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
or 1.25 hr.
