7 miles per hour.
if you multiply the distance and time by 2 you get 7 miles in 1 hour, or 7 mph
Answer:
C
Step-by-step explanation:
The sum to n terms of a geometric sequence is
= 
Here a₁ = 4 and r = - 3, thus
= 
= 
= - (729 - 1) = - 728 → C
Answer:
yes
Step-by-step explanation:
8² + 15² = 17²
64 + 225 = 289
289 = 289
We are given the following data
x y
1 4.5
2 6.75
3 10.125
4 15.1875
To get the multiplicative rate of change, we pick out two pairs of data so,
MROC = 6.75/4.5 / (2 - 1)
MROC = 1.5
The answer is 1.5
