PLEASE ANSWER QUICK!!Describe the connection between the y intercept of a polynomial function and the
function's rational roots.

Answer:

It's graph is symmetric to the origin. Cos (x) on the other hand is an even function cos (-x) = cos (x), and its graph is symmetric to the y-axis. Notice also that the graphs are exactly the same shape but horizontally shifted /2 units. They are related by: sin (x) = cos (x - /2) and cos (x) = sin (x + /2).

Answer:

C. r = 28.50 ÷ 3

Step-by-step explanation:

You have to divide to see the rate

Given:

[tex]\to \text{time}= 3 \ hours\\\\\to \text{total eran}= \$28.50 \\\\[/tex]

To find:

earn per hour=?

Solution:

[tex]\to \text{time}= 3 \ hours\\\\\to \text{total eran}= \$28.50 \\\\[/tex]

calculate earn per hour:

[tex]= \frac{\text{total earn }}{ \text{time}}\\\\= \frac{28.50}{3}\\\\= \$ 9.5\\\\[/tex]

Therefore, the answer is "$9.5".

Answer:

x=4, x= -1

Step-by-step explanation:

Write your problem:

[tex]x^{2}[/tex] - 4 = 3x

Subtract 3x from both sides:

[tex]x^{2}[/tex] - 4 - 3x = 3x - 3x

Simplify:

[tex]x^{2}[/tex] - 3x - 4 = 0

The measure of DE is 130 degrees if the measure of DEF is 65 in the circle option (A) is correct.

A circle is a shape consisting of all points in a plane that are at a given distance from a given point, the centre.

Circle is described as a set of points, where each point is at the same distance from a fixed point (called the center of a circle)

We have:

The measure of DEF = 65 degrees

C is the center.

Angle CED = 90 - 65 = 25 degrees

Angle DCE = 180 - 25 - 25

Measure of DE = 130 degrees

Thus, the measure of DE is 130 degrees if the measure of DEF is 65 option (A) is correct.

Answer:

13cm

Step-by-step explanation:

The pythagorean theorem states that, for right triangles, [tex]a^{2} +b^{2} =c^{2}[/tex]. Using this equation, we can solve for the hypotenuse.

a = 12cm

b = 5cm

c = hypotenuse

[tex]12^{2} +5^{2} =c^{2}[/tex]

[tex]144+25=c^{2}[/tex]

[tex]\sqrt{169} =c[/tex]

13 = c

Answer:

13

Step-by-step explanation:

a^2+b^2=c^2

12^2+5^2=c^2

144+25=c^2

Answer:

The length of the rectangle is 28 inches.

Step-by-step explanation:

We have that the width (W) of a rectangle is half of the length (L) of the rectangle:

[tex] W = \frac{1}{2}L [/tex]  (1)

Also, the perimeter is 84 inches:

[tex] P = 2W + 2L = 84 in [/tex]   (2)

By entering equation (1) into equation (2) we have:

[tex]2(\frac{1}{2}L) + 2L = 84 in[/tex]

[tex] L = \frac{84}{3} = 28 in [/tex]

Therefore, the length of the rectangle is 28 inches.

D is the correct fraction

Answer:

20, 68%, 0.687

Step-by-step explanation:

If 20 were to be a percentage, then it'll be less than 68% and 0.687. Since the 7 in 0.687 is greater than 5, you would round up when the question says so. 0.687 is greater than 68%; if you move the decimal 2 times to the right, then 0.687 would be 68.7%. Therefore the order from least to greatest is 20, 68%, 0.687.

Answer:

4x+2(2x−5)−(3−5x) = 8x-10-3+5x

Step-by-step explanation:

We need to find the equivalent expression to 4x+2(2x−5)−(3−5x).

Using distributive property as follows :

a(b+c) = ab+ac

4x+2(2x−5)−(3−5x) = 4x+4x-10-3+5x

= 8x-10-3+5x

Option (e)

Hence, the correct option is (e) "8x-10-3+5x"

Answer:

The mean of tree heights at Yard Works is 8 feet. The mean of tree heights at The Grow Station is 9 feet. The mean absolute deviations of the tree heights at both yards is 2.

Answer:

The heights, in feet, of the trees for sale at two nurseries are shown below.

Yard Works: 7, 9, 7, 12, 5

The Grow Station: 9, 11, 6, 12, 7

Which statements are true regarding the measures of center and variability of these data sets? Select three choices.

________________________________________________________

1  The mean of the tree heights at Yard Works is less than the mean of the tree heights at The Grow Station.

2  The median of the tree heights at Yard Works is greater than the median of the tree heights at The Grow Station.

3  The range of the tree heights at Yard Works is greater than the range of the tree heights at The Grow Station.

4  The mean absolute deviation of the tree heights at Yard Works is greater than the mean absolute deviation of the tree heights at The Grow Station.

5  The mean absolute deviation of the tree heights at Yard Works is equal to the mean absolute deviation of the tree heights at The Grow Station.

Step-by-step explanation:

Yard works has...

mean=8

median=7

mode=7

range=11

because in order it is 5 7 7 9 12

(5+7+7+9+12)/5=8

5 7( 7 )9 12 is the median

and seven occurs the most

and with this logic...

THE GROWSTATION has a

mean=9

median=9

mode=n/a

range=6
