We need to multiply the factors (x - 2) and (x^2 + 9x + 10) to see if the product is the original expression given.

(x - 2)(x^2 + 9x + 10)

x^3 + 9x^2 + 10x - 2x^2 - 18x - 20

x^3 + 7x^2 - 8x - 20.

Since the product just found is not the original expression given, Jimmy is wrong.

I will complete the work on paper by synthetic division and post my answer.

After using synthetic division, the correct quotient is x^2 + 9x + 20.

30 POINTS PLS HELP

zysi [14]

Answer:

We proceed to use the following operations: (i) Vertical translation downwards ( $k = -\frac{1}{2}$ ), (ii) Vertical compression ( $c = \frac{1}{2}$ ), (iii) Vertical translation upwards ( $k = \frac{1}{2}$ ). The graph is presented below.

Step-by-step explanation:

To transform $y = \frac{5}{4}\cdot x + \frac{1}{2}$ into $y = \frac{5}{8}\cdot x + \frac{1}{2}$ , we apply the following steps:

(i) Vertical translation downwards ( $k = -\frac{1}{2}$ )

$g(x) = f(x) +k$ (1)

(ii) Vertical compression ( $c = \frac{1}{2}$ )

$g(x) = c\cdot f(x)$ (2)

(iii) Vertical translation upwards ( $k = \frac{1}{2}$ )

$g(x) = f(x) + k$

Now, we proceed to transform the primitive expression:

Step 1

$f'(x) = \frac{5}{4}\cdot x$

Step 2

$f''(x) = \frac{5}{8}\cdot x$

Step 3

$g(x) = \frac{5}{8}\cdot x + \frac{1}{2}$

The graph of both function are now presented below. The parent function is the red line and the new function is represented by the blue line.

I need help on this problem 20 ÷ (4 - (10 - 8))

vlada-n [284]

Answer: 10

Explanation:

20 ÷ (4- (10-8))

First off, you work your way outward. You start the furthest in, then head your way out. (10 - 8) is the furthest in, and 10 - 8 = 2. So now your equation looks like this:

20 ÷ (4 - 2)

Next, you do the (4 - 2) which equals 2. So now, the equation is this:

20 ÷ 2

So you finish it up with 20 ÷ 2 which equals 10.

Hope I made sense! :D

A. 9.49 B. 8.49 C.0 D.72 help asap thank you!

kicyunya [14]

Answer:

A. 9.49

Step-by-step explanation:

Use Pythagorean theorem to find the distance and make a right triangle.

So then..

a² + b² = c²

3² + 9² = c²

c² = 9 + 81

c² = 90

c² = $\sqrt{90}$

c = 9.49
