A factory is discharging pollution into a lake at the rate of r(t) tons per year given below, where t is the number of years tha
alexandr402 [8]

Answer:

The total amount of pollution discharged during the first 7 years of operation is 1.955 tons

Step-by-step explanation:

Given

r(t) = \frac{t}{t^2 + 1}

Required

The total amount in the first 7 years

This implies that:

r(t) = \frac{t}{t^2 + 1}; [0,7]

The total amount is calculated by integrating r(t) i.e.

v = \int\limits^a_b {r(t)} \, dt

So:

v = \int\limits^7_0 {\frac{t}{t^2 + 1}} \, dt

--------------------------------------------------------------

We have:

t^2 + 1

Differentiate

d(t^2 + 1) = 2t

Rewrite as:

2t = d(t^2 + 1)

Solve for t

t = \frac{1}{2}d(t^2 + 1)

---------------------------------------------------------------------------

So:

Make t the subject

v = \int\limits^7_0 {\frac{t}{t^2 + 1}} \, dt

v = \int\limits^7_0\frac{1}{2}* {\frac{d(t^2 + 1)}{t^2 + 1}} \, dt

v = \frac{1}{2}\int\limits^7_0 {\frac{d(t^2 + 1)}{t^2 + 1}} \, dt

Integrate

v = \frac{1}{2}\ln(t^2 +1)|\limits^7_0

Expand

v = \frac{1}{2}[\ln(7^2 +1) - \ln(0^2 +1)]

v = \frac{1}{2}[\ln(50) - \ln(1)]

v = \frac{1}{2}[3.91 - 0]

v = \frac{1}{2}[3.91]

v = 1.955

Point C is the center of the circle. The measure of angle ACB is 3x+20. Arc AB measures 65x-4. Find measure of arc AB
NISA [10]
In a circle the measure of a CENTRAL angle = measure of the arc intercepted.
mes Angle ACB = mes Arc AB:

3x+20 = 65x-4
24 = 65x -3x

62x = 24
x = 24/62 = 12/31 = 0.3871
