Dr/dt= 8cmM-¹
dA/dt = ?
but A= πr²
so dA/dr =2πr
but recall
dA/dt = dA/dr • dr/dt
dA/dt = 2πr • 8cmM-¹
dA/dt = 2×π×39 ×8 = 624cm²M-1
The domain is all the x values (range is y values). Remember to put the x values in numerical order.
So: Domain = {-5, -5, -2, 3}.
1 is 0.0012. 2 is 3.25 and 3 is 3.25
Answer:
4 and 5
Step-by-step explanation:
4 x 5 = 20
4 + 5 = 9
