write the equation of the polynomials in factored form that has the following zeros: -8, -4, 5, 5, 2
Answers
Explanation:
When finding a zero, you set the equation equal to 0 then solve.
For example, x+8=0
You would isolate x by subtracting both sides by 8 and get x=-8. This mean that the root or zero is -8. When there are two zeros that are the same, you just square the equation.

Answers
Answer:
1.25
5/4
1 1/4
Step-by-step explanation:
The dimensions of rectangle A are L=12 and W=8. The dimensions of rectangle B are L=15 and W=10.
We are told rectangle B is a copy of rectangle A, thus we must find the scale factor by dividing both dimensions:
15/12=5/4
10/8 =5/4
Dividing 5/4 we get 1.25.
Converting 5/4 to mixed fraction: 5/4= 1 1/4
There are three valid selections:
1.25

A piece of paper is to display ~128~ 128 space, 128, space square inches of text. If there are to be one-inch margins on both sides and two-inch margins at the bottom and top, what are the dimensions of the smallest piece of paper (by area) that can be used? Choose 1 answer:
Answers
Answer:
The dimensions of the smallest piece that can be used are: 10 by 20 and the area is 200 square inches
Step-by-step explanation:
We have that:
[tex]Area = 128[/tex]
Let the dimension of the paper be x and y;
Such that:
[tex]Length = x[/tex]
[tex]Width = y[/tex]
So:
[tex]Area = x * y[/tex]
Substitute 128 for Area
[tex]128 = x * y[/tex]
Make x the subject
[tex]x = \frac{128}{y}[/tex]
When 1 inch margin is at top and bottom
The length becomes:
[tex]Length = x + 1 + 1[/tex]
[tex]Length = x + 2[/tex]
When 2 inch margin is at both sides
The width becomes:
[tex]Width = y + 2 + 2[/tex]
[tex]Width = y + 4[/tex]
The New Area (A) is then calculated as:
[tex]A = (x + 2) * (y + 4)[/tex]
Substitute [tex]\frac{128}{y}[/tex] for x
[tex]A = (\frac{128}{y} + 2) * (y + 4)[/tex]
Open Brackets
[tex]A = 128 + \frac{512}{y} + 2y + 8[/tex]
Collect Like Terms
[tex]A = \frac{512}{y} + 2y + 8+128[/tex]
[tex]A = \frac{512}{y} + 2y + 136[/tex]
[tex]A= 512y^{-1} + 2y + 136[/tex]
To calculate the smallest possible value of y, we have to apply calculus.
Different A with respect to y
[tex]A' = -512y^{-2} + 2[/tex]
Set
[tex]A' = 0[/tex]
This gives:
[tex]0 = -512y^{-2} + 2[/tex]
Collect Like Terms
[tex]512y^{-2} = 2[/tex]
Multiply through by [tex]y^2[/tex]
[tex]y^2 * 512y^{-2} = 2 * y^2[/tex]
[tex]512 = 2y^2[/tex]
Divide through by 2
[tex]256=y^2[/tex]
Take square roots of both sides
[tex]\sqrt{256=y^2[/tex]
[tex]16=y[/tex]
[tex]y = 16[/tex]
Recall that:
[tex]x = \frac{128}{y}[/tex]
[tex]x = \frac{128}{16}[/tex]
[tex]x = 8[/tex]
Recall that the new dimensions are:
[tex]Length = x + 2[/tex]
[tex]Width = y + 4[/tex]
So:
[tex]Length = 8 + 2[/tex]
[tex]Length = 10[/tex]
[tex]Width = 16 + 4[/tex]
[tex]Width = 20[/tex]
To double-check;
Differentiate A'
[tex]A' = -512y^{-2} + 2[/tex]
[tex]A" = -2 * -512y^{-3}[/tex]
[tex]A" = 1024y^{-3}[/tex]
[tex]A" = \frac{1024}{y^3}[/tex]
The above value is:
[tex]A" = \frac{1024}{y^3} > 0[/tex]
This means that the calculated values are at minimum.
Hence, the dimensions of the smallest piece that can be used are: 10 by 20 and the area is 200 square inches

Abes apples orchard plants both green apple trees and red apple trees this planting will include 21 red apple trees and 18 green apple trees what is the ratio of green apple trees and red apple trees
Answers
Answer:
The ratio of green apples to red apples is .
Step-by-step explanation:
Given,
Number of red apples = 21
Number of green apples = 18
We have to find out the ratio of green apples to red apples.
Solution,
For finding the ratio we have to divide the number of green apples to the number of red apples.
So, we can frame the above sentence as;
Ratio = number of green apples/number of red apples
Now substituting the values, we get;
Ratio= 18/21 = 6/7
Hence The ratio of green apples to red apples is . 6/7

What’s the measure of angle X?
Answers
Answer:
x = 84°
Step-by-step explanation:
The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.
129° is an exterior angle of the triangle, thus
x + 45° = 129° ( subtract 45° from both sides )
x = 84°

crickets and
grasshoppers
Answers
Answer:
Arielle has 374 grasshoppers and 187 crickets
Step-by-step explanation:
Let's set:
x = number of grasshoppers
y = number of crickets
Arielle has a collection of 561 insects, thus:
x + y = 561 [1]
The number of grasshoppers is twice the number of crickets, thus:
x = 2y [2]
Substituting [2] in [1]:
2y + y = 561
Simplifying:
3y = 561
Dividing by 3:
y = 561/3
y = 187
From [2]:
x = 2*187 = 374
x = 374
Arielle has 374 grasshoppers and 187 crickets
