Answer:
37.7 mi²/h
Step-by-step explanation:
The area formula is ...
A = πr²
Differentiating with respect to time gives ...
dA/dt = 2πr·dr/dt
Filling in the given values, we have ...
dA/dt = 2π(3 mi)(2 mi/h) = 12π mi²/h
The area is increasing at the rate of about 37.7 mi² per hour.
3.1 i think but hopefully that might help
Your answer should be D because 13-10=3 and 10-3=7 (2, 7)!
Step-by-step explanation:
x³ - 4x² + 3x

= x(x -3)(x - 1)
× = 0, 1, 3
