V=(1/3)πr²h
∴ dV/dt
=(π/3)[r²(dh/dt)+h2r(dr/dt)]
=(π/3)[(30)²(-2)+40(2)(30)(2)]
=(π/3)[-1800+4800]
=1600π in³/sec
Answer: 1600π in³/sec
Answer:
it's equal to 21 when I say it's equal to 21
Answer:
The domain is all real numbers less than or equal to two-third
Step-by-step explanation:
<u><em>The question in English is</em></u>
Determine the domain of the function f :D→R, 
we know that
The radicand of the function must be greater than or equal to zero
so

Solve the inequality for x
subtract 2 both sides

Multiply by -1 both sides

Divide by 3 both sides

The solution is the interval ----> (-∞,2/3]
therefore
The domain is all real numbers less than or equal to two-third
Answer:
Base x Height x Width
Step-by-step explanation:
Helen should of put 0 first, because if you're gonna divide, you need to put the product first, then one of the factoes.
So instead it should be 0÷(-7)=0
