polygon b is a scaled copy of polygon a using a scale factor of 5 . polygon a area is what fraction of polygon b area
Answers
The area of polygon A would be a fraction 1/25 of the size of polygon B.
What is a scale image?Scale image is defined as a ratio that represents the relationship between the shape and size of a figure and the corresponding dimensions on the actual figure or object
The formula of the scale factor is shown as;
Area of Polygon B = (scale factor)²×(Area of Polygon A).
Using a scale factor of 5, we get
(Area of Polygon B) = (5)²× (Area of Polygon A)
(Area of Polygon B) = (25) × (Area of Polygon A)
Area of Polygon A = (1/25) × Area of Polygon B
Therefore, the area of polygon A would be a fraction 1/25 of the size of polygon B.

What is the range of the function f(x)=6x^2+x-1/2x^2+x-6
Answers
Answer:
Range: [tex]\:f\left(x\right)\ge \:-\frac{68}{11}[/tex]
Interval notation [tex][-\frac{68}{11},\:\infty \:)[/tex]
Step-by-step explanation:
I got a little confused with the x - 1/2x^2 term and I am taking to to be:
[tex]x\:-\frac{1}{2}x^2[/tex] . If this is incorrect please mention the correct term in your comment and I will edit this post. Or you can re-post the question
We have
[tex]f\left(x\right)=6x^2+x\:-\frac{1}{2}x^2+\:x\:-\:6[/tex]
Simplify by grouping like terms:
[tex]=-\frac{1}{2}x^2+6x^2+x+x-6[/tex]
[tex]= \frac{1}{2}x^2+6x^2+2x-6[/tex]
Add similar elements
[tex]-\frac{1}{2}x^2+6x^2[/tex][tex]= -\frac{1x^2}{2}+\frac{12x^2}{2} = \frac{11x^2}{2}[/tex]
So the original function expression becomes
[tex]y=\frac{11}{2}x^2+2x-6[/tex]
This is the equation of a parabola which in standard form is [tex]ax^2 + bx + c[/tex]
Here
[tex]a=\dfrac{11}{2},\:b=2,\:c=-6[/tex]
We can compute the vertex of this parabola using the fact that the x, y coordinates of the vertex are given by
[tex]x_v =-\dfrac{b}{2a}[/tex]
Plugging in values for b and a give us
[tex]x_v =-\dfrac{b}{2a} = -\dfrac{2}{2\left(\dfrac{11}{2}\right)} =-\dfrac{2}{11}[/tex]
Plugging in this value of [tex]x_v[/tex] into the parabola equation will give the value for [tex]y_v[/tex] which is the function value at the vertex
Plug in [tex]x_v = -\frac{2}{11}[/tex] t find the [tex]y_v[/tex] value:
[tex]y_v=\dfrac{11\left(-\dfrac{2}{11}\right)^2}{2}+2\left(-\dfrac{2}{11}\right)-6[/tex]
Simplify
[tex]\dfrac{11\left(-\dfrac{2}{11}\right)^2}{2} =\dfrac{2}{11}[/tex]
[tex]2\left(-\dfrac{2}{11}\right) = -\dfrac{4}{11}[/tex]
Combining the terms we get
[tex]y_v =[/tex] [tex]\dfrac{2}{11}-\dfrac{4}{11}-6[/tex] [tex]= -\dfrac{68}{11}[/tex]
[tex]\textsf{Therefore the parabola vertex is at }[/tex] [tex]\left(-\dfrac{2}{11},\:-\dfrac{68}{11}\right)[/tex]
For a parabola of the form [tex]ax^2 + bx + c[/tex] with vertex [tex]\left(x_v,\:y_v\right)[/tex]
[tex]\circ \;\mathrm{If}\:a < 0\:\mathrm{the\:range\:is}\:f\left(x\right)\le \:y_v[/tex]
[tex]\circ \;\mathrm{If}\:a > 0\:\mathrm{the\:range\:is}\:f\left(x\right)\ge \:y_v[/tex]
Here [tex]a=\frac{11}{2}[/tex] so the range is [tex]f\left(x\right)\ge \:-\dfrac{68}{11}[/tex]
Answer range of f(x) is
[tex]f\left(x\right)\ge \:-\dfrac{68}{11}[/tex]
In interval notation it is [tex][-\frac{68}{11},\:\infty \:)[/tex]

The equation that we would use to find the value of x based on the area of a rectangle is:
C. (16 + 2x)(12 + 2x) = 396
What is the Area of a Rectangle?To find the area of a rectangle, find the product of its length and its width. Thus, the area of a rectangle is: (length)(width) = area.
Given the following:
Area of both the walkway and the garden = 396 square meters
Length = x + 16 + x = 16 + 2x
Width = x + 12 + x = 12 + 2x
Using the area formula for a rectangle, we would have:
(16 + 2x)(12 + 2x) = 396.

a local nonfrofit organization is selling popcorn to raise money for hurrican relief. the organization paid $4 per bag for the popcorn and sold $5 per bag. what was the percent makeup on each bag of popcorn?
Answers
The percent makeup on each bag of popcorn is 25%.
When a fraction of a whole is expressed as a number between 0 and 100, it is called a percentage. The percentages 100%, 50%, 0% indicate all of some quantity, half of the quantity, and none of the quantity respectively.
Popcorn is being sold by a neighborhood nonprofit to support hurricane relief.
The organization paid $4 for each bag of popcorn.
The organization sold each bag of popcorn for $5.
The markup or gain from selling the popcorn is:
$5 - $4 = $1
Therefore, the percent makeup on each bag of popcorn will be:
= ( the gain / the amount organization paid for each bag ) × 100
= ( 1 / 4) × 100
= 0.25 × 100
= 25 %

1. x + x = 10
2. y + z= 9
3. y+ x = 8
solving equation 1
x + x = 10
2x = 10
x = 5
Putting the value of x in equation 3
y + x=8
y + 5 = 8
y = 3
Putting the value of y in equation 2

Under his cell phone plan, Carson pays a flat cost of $37.50 per month and $3 per gigabyte. He wants to keep his bill under $40 per month. Which inequality can be used to determine g, the maximum number of gigabytes Carson can use while staying within his budget?
Answers
Based on the flat cost paid by Carson for his cell phone plan, and the amount of he wants to keep his bill under, the inequality that can be used to determine g is 37.50 + 40g ≤ 40
How to find the inequality?The inequality that can be used to find the maximum number of gigabytes that Carson can use while staying in his budget can be found as:
Flat cost for the cell phone plan + Cost per gigabyte x Number of gigabytes ≤ Maximum preferred bill by Carson
When we put in the figures from Carson's cell phone plan, we get:
37.50 + 3 x g ≤ 40
37.50 + 3g ≤ 40

Athena's credit card has an APR of 16.99%. If her current monthly balance, before interest, is $1,567.32, what amount will she be charged for interest?
a)$22.19
b)$26.63
c)$31.19
d) $45.00
Answers
The amount that Athena will be charged for interest is $22.19
What is the meaning of APR of 16.99%?
The APR means an annual percentage rate, which means that the 16.99% is annual interest rate compounded monthly, hence, it needs to be divided by 12 in order to determine the equivalent monthly interest rate.
monthly interest rate=16.99%/12
monthly interest rate=0.0141583333333333
The monthly interest charged on the balance of $1,567.32 is computed thus:
