use the equation 4/3 *r^3 *pi for each, then find the difference
Answer:
$375
Step-by-step explanation:
Step 1: Set up expression
150(1 + 150%)
Step 2: Convert %
150(1 + 1.5)
Step 3: Solve
150(2.5)
375
∫f(6)-∫f(1) = 1, ∫f(6)-∫f(3)=6, and ∫f(7)-∫f(1)=7. Changing around the first and third equation, we can get ∫f(1)=∫f(6)-1, and ∫f(1)=∫f(7)-7. Then we get that ∫f(6)-1=∫f(7)-7, and that ∫f(6)=∫f(7)-6. Then plug into the second equation, to get ∫f(7)-6-∫f(3)=6 or ∫f(7)-∫f(3)=12. So <span>∫73f(x)dx = 12.</span>
The 2nd one i'm pretty sure i did it with a calculator
