If a tank holds 4500 gallons of water, which drains from the bottom of the tank in 50 minutes, then Toricelli's Law gives the vo

disa [49]

Answer:

The response to this question can be defined as follows:

Step-by-step explanation:

$v =4500 (1-\frac{t}{50})^2\\\\\to \frac{dV}{dt}= 9000 (1- \frac{t}{50})(\frac{1}{50})\\\\$

$= 180 (\frac{50-t}{50})\\\\= 3.6(50-t)\\\\$

For point a:

$t=5\\\\V'=3.6\times 45 = 162\\\\ans= - 162\ \frac{gal}{min}\\\\$

For point b:

$t=10\\\\V'=3.6\times 40 = 144\\\\ans= - 144 \ \frac{gal}{min}\\\\$

For point c:

$t=20\\\\V'=3.6\times 30 = 108\\\\ans= - 108 \ \frac{gal}{min}\\\\$

For point d:

$t=50\\\\V'=3.6\times 0 = 0\\\\ans= 0 \ \frac{gal}{min}\\\\$
