Answer:
Use shell method
And chose the cross section perpendicular to the x-axis
The diver is moving down, so he moved −20 feet. Start with 20 negative tiles and separate them into 5 equal groups. There are 4 negative tiles in each group, so he traveled at a rate of −4 feet per second.
Answer:
true
Step-by-step explanation:
sinA² + cosA²=1
⇔(1/2)² + cosA²=1
⇔cosA=±(√3/2)
Answer:
1.5
Step-by-step explanation:
F(x)=2x+1
For F(x) = 4
F(x)=2x+1 = 4
2x = 4 - 1
2x = 3
Dividing through by 2
2x/2 = 3/2
X = 3/2 = 1.5
