Answer:
option a
Step-by-step explanation:
y^7/8 / y^1/4
First we will accommodate the fractions
1/4 = 2/8
y^7/8 / y^2/8
Then we will subtract the exponents of the powers since they have the same base and are dividing
7/8 - 2/8 = 5/8
y^5/8
Finally we pass the 8 as radical root
8√y^5
Hey, here it is: 2,4 x 10^-6
Here's a solution for #8
Volume of a sphere = V = 4/3π r³
Your radius r = 6, so plugging that in you get:
V = 4/3π(6³)
V = 4/3π216
V = 864/3π
V = 288π (units³)
Answer:
rate of change = 1.5 dollars per mile
Step-by-step explanation:
cost for travelling 1 mile = 3.75
cost 2 miles = 5.25
cost 3 miles = 6.75
cost 4 miles = 8.25
120 because 60 times two is 120 and six times two is twelve
