Answer:
hello the answer is .04/0.04
Answer:
8πcm²/sec
Step-by-step explanation:
The radius of the circle increases at a rate of dr/dt = 0.25cm/sec
The radius of the circle r = 16cm
The area of the circle increases at a rate of dA/dt = ?
Area of a circle = πr²
We take the derivative with respect to t
dA/dt = 2πrdr/dt
dA/dt = 2 π (16)(0.25)
dA/dt = 8πcm²/sec
Thank you!!!
4z + 2
2z 8z^2 + 4z - 5
- 8z^2
4z - 5

(8z^2 + 4z - 5) ÷ 2z = 4z + 2 R -5
