$4x-40y=4\\40y=4x-4\\y=\frac{4}{40}-\frac{4}{40}\\y=\frac{1}{10}x-\frac{1}{10}\\$

Here, 1/10 is the slope and 1/10 is the Y intercept.

A chemical flows into a storage tank at a rate of (180+3t) liters per minute, where t is the time in minutes and 0<=t<=60

Yuliya22 [10]

Answer:

The amount of the chemical flows into the tank during the firs 20 minutes is 4200 liters.

Step-by-step explanation:

Consider the provided information.

A chemical flows into a storage tank at a rate of (180+3t) liters per minute,

Let $c(t)$ is the amount of chemical in the take at <em>t </em>time.

Now find the rate of change of chemical flow during the first 20 minutes.

$\int\limits^{20}_{0} {c'(t)} \, dt =\int\limits^{20}_0 {(180+3t)} \, dt$

$\int\limits^{20}_{0} {c'(t)} \, dt =\left[180t+\dfrac{3}{2}t^2\right]^{20}_0$

$\int\limits^{20}_{0} {c'(t)} \, dt =3600+600$

$\int\limits^{20}_{0} {c'(t)} \, dt =4200$

So, the amount of the chemical flows into the tank during the firs 20 minutes is 4200 liters.

A roll of quarters is shaped like a cylinder and contains 40 each quarter has a thickness of 1.75 and a diameter of 24.26 mm Wha

jarptica [38.1K]

Answer:

D) 32,357mm^3

Step-by-step explanation:

Given

$Quarters = 40$

$Thickness = 1.75mm$

$diameter = 24.26mm$

First, we calculate the volume of 1 roll.

The volume of the cylinder is:

$V = \pi r^2h$

Where

$r = \frac{1}{2} * diameter$

$r = \frac{1}{2} * 24.26mm$

$r = 12.13mm$

And the thickness represents the height.

So:

The volume is:

$V = 3.142 * 12.13^2 * 1.75$

$V = 809.03mm^3$

The volume of the 40 is:

$Roll= 40 * 809.03mm^3$

$Roll=32361.20mm^3$

The closest option is (d):
