Answer:
15 and 270
Step-by-step explanation:
Using the rule of radicals
× = a
![\sqrt[3]{a}](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7Ba%7D)
× × = a
(a)
Given
(
)² × (
)²
= 5 × 3
= 15
(b)
Given
(![\sqrt[3]{9}](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B9%7D)
)³ × (
)²
= 9 × 30
= 270
Kim = 135/9 = 15 miles per week
Eric = 102/6 = 17 miles per week
Eric rode more.
y = Acos(Bx) + D;
D = 4, A = 2. Now T = 2π/B = 5π/8, B = 2π/(5π/8) = 16/5
WE get y = 2cos(16/5x) + 4
Use the formula:
Radio= r, Height= h
V= 3.14xrx2h
r =25, h=31
V= 3.14 x 25 x 2 (31) =. 4867
V= 4867 cubic inches
