notka56 [123]

Answer:

-5 times 12 is a binomial

Step-by-step explanation:

two terms = binomial

HOWEVER IF IT's -5.12 then it's a monomial because it's one term

there are 44 people working at the plaza office building. Tuesday 3/4 of the worked overtime. how many people worked overtime?

Andru [333]

So there are 44 people and in Tuesday, 3/4 I'd them stay overtime. In order to answer this divide 3 with 4 first into 0.75 in which you will multiply with 44

So the answer is 33, 33 people stayed over tine

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
