One factor of the polynomial 3x3 + 20x2 - 21x + 88 is (x + 8). what is the other factor of the polynomial? (note: use long divis

Snezhnost [94]

The other factor of the polynomial is a. 3x2-4x+11

Given polynomial is 3x3 + 20x2 - 21x + 88 and the factor is (x+8)

We need to find another factor using long division method

So,

We will divide the polynomial by the factor to find the another factor

Therefore,

$\sqrt[x+8]{3x^3+20x^2-21x+88}$

Now calculating

First multiplying $3x^2$ with (x+8) so , $3x^2$ will be in the quotient

We get $3x^3+24x^2$

simplifying the calculation for $3x^3+20x^2$ and $3x^3+24x^2$

We get the remainder is $-4x^2-21x+88$

Second we will multiply -4x with (x+8) Where -4x will be in the quotient

We get $-4x^2-32x$ and then we will simplify the equation

We get 11x +88 as a remainder

The quotient we get is $3x^2-4x$

Third we will multiply +11 with (x+8) Where +11 will be in the quotient

we get 11x+88

Simplifying the equation we get the remainder 0

So the quotient we get is (3x2 - 4x+11)

Hence the another factor of the polynomial is (3x2 - 4x+11)

16) A company has found that its expenditure rate per day (in hundreds of dollars) on a certain type of job is given by E'(x) =

erastova [34]

Answer:

$61

Step-by-step explanation:

Given

Number of days, x = 5

Expenditure per day, E'(x) = 10x + 11

Required

Determine the expenditure per day (E'(x))

From the question, we have that

$E'(x) = 10x + 11$

Substitute 5 for x

$E'(5) = 10 * 5 + 11$

$E'(5) = 50 + 11$

$E'(5) = 61$

Hence, the expenditure for 5 days is $61

The length of a rectangle is 2 in longer than its width. if the perimeter of the rectangle is 44 in , find its area.

valkas [14]

P = 2(L + W)
P = 44
L = W + 2

44 = 2(W + 2 + W)
44 = 2(2W + 2)
44 = 4W + 4
44 - 4 = 4W
40 = 4W
40/4 = W
10 = W

L = W + 2
L = 10 + 2
L = 12

A = L * W
L = 12
W = 10

A = 12 * 10
A = 120 square inches <===

Find the value of the trigonometric ratio.<br> Answer has to be a reduced ratio.<br> PLS HELP!!

zloy xaker [14]

Answer:

3/5

Step-by-step explanation:

I'm not completely sure but from what I see it says 'sin <em>C </em>' and both 12 , 20 are on C.

so i simply just did 12/20

reduced once - 6/10

reduced twice - 3/5

HELP HELP ME PLZ !!!

nikklg [1K]

Answer:

GK=JK

Step-by-step explanation:

SSS congruency is side-side-side congruency. We are given that GH=JH and KH=KH, which are both sides.

For SSS, we need 3 pairs of congruent sides. We already have 2 pairs.

The options are:

<G=<J

<H=<H

GK=JK

the first two options, <G=<J and <H=<H are talking about congruent angles. We don't need to know about congruent angles for SSS

GK=JK is talking about a pair of congurent sides. Then, we would have 3 pairs of congruent sides, satisfying the criteria needed for SSS. Therefore, we must know that GK=JK.

Hope this helps!
