<u>Answer:</u>

The correct answer option is B. $1$ , $\frac{1}{2}$ , $\frac{1}{4}$ .

<u>Step-by-step explanation:</u>

We are given the following geometric sequence and we are to find its 8th term:

$16, 8, 4, 2,...$

Here $a_1=16$ and common ratio $(r) = \frac{2}{4}=0.5$ .

The formula we will use to find the next three terms is:

nth term = $a_1 \times r^{(n-1)}$

5th term = $16 \times 0.5^{(5-1)} = 1$

6th term = $16 \times 0.5^{(6-1)}$ = $\frac{1}{2}$

7th term = $16 \times 0.5^{(7-1)}$ = $\frac{1}{4}$

If the length I of a rectangle is 3 more than twice the width w. The area is 90. Find the width

rjkz [21]

Answer:

w = 6

Step-by-step explanation:

Givens

Area = 90

Let the width = w

Let the length = 2w + 3

Formula

Area = L * W

Solution

Area = (2w + 3)*w

Area = (2w + 3)* w = 90 Remove the brackets.

Area = 2w^2 + 3w = 90 Subtract 90 from both sides.

2w^2 + 3w - 90 = 0

This will factor into

(w - 6)(2w + 15) = 0

Only w - 6 will = a zero that makes sense when speaking of an area

w - 6 = 0

w = 6

L = 2*w + 3

L = 2*6 + 3

L = 15

The width is 6

Divide using long division. check your answers. 1. (x 3 – 13x 2 + 7x – 48) ÷ (x 2 + 3) 3. (x 3 + 5x 2 – 3x – 1) ÷ (x – 1) 5. (x

1. We can conclude that the result of the division is $x-13$ with a remainder of $4x-9$ , or in other notation: $x-13+ \frac{4x-9}{x^2+3}$ . Check the steps in the first image.

3. We can conclude that the result of the division is $x^{2} +6x+3$ with a remainder of 2, or in other notation: $x^{2}+6x+3+ \frac{2}{x-1}$ . Check the steps in the firts image.

5. We can conclude that the result of the division is $x+1$ with a remainder of 5, or in other notation: $x+1+ \frac{5}{x-4}$ . Check the steps in the first image.

7. To check if $x+4$ is a factor of $x^{3}+3x^{2}-10x-24$ , we are going to perform long division. If the result of the long division has no remainder, $x+4$ is a factor of $x^{3}+3x^{2}-10x-24$ .
Since the result of the long division has no remainder, we can conclude that $x+4$ is a factor of $x^{3}+3x^{2}-10x-24$ . Check the steps in the second image.

9. To check if $x-3$ is a factor of $x^{3}+3x^{2}-10x-24$ , we are going to perform long division. If the result of the long division has no remainder, $x-4$ is a factor of $x^{3}+3x^{2}-10x-24$ .
Since the result of the long division has no remainder, we can conclude that $x-4$ is a factor of $x^{3}+3x^{2}-10x-24$ . Check the steps in the third image.

10. We can conclude that the result of the synthetic division is $-2x^{2}+9x+5$ . Check the steps in the fourth image.
