Find the missing sides and find perimeter and area for this shape
Brainiest answer to whoever is first to answer
Answers
Step-by-step explanation:
Given
A semi-circle is placed over a rectangle
width of the rectangle is w=1.5 cm
The length of the rectangle is l=9.2 cm
from the figure, we can write
[tex]\Rightarrow 9.2=2.5+2r\quad (\text{length of rectangle is equal})[/tex]
where r=radius of the semi-circle
[tex]\Rightarrow 2r=6.7\\\Rightarrow r=3.35\ cm[/tex]
Perimeter of figure
[tex]\Rightarrow 9.2+1.5+2.5+\pi r+1.5\\\Rightarrow 14.7+10.52=25.22\ cm[/tex]
Area of the figure
[tex]\Rightarrow A=\text{Area of rectangle+Area of semi-circle}\\\Rightarrow A=1.5\times 9.2+\pi \times 3.35^2\\\Rightarrow A=13.8+35.26=49.06\ cm^2[/tex]

Determine all the transformations that have happened to f(x) = (x + 4)2 + 2 compared to
f(x) = x2
Answers
Answer:
Folow the steps to learn what transformations were determined.
Step-by-step explanation:
First we would have to graph the parent function which is f(x) = x^2. Start by finding your x and y values. Find the y values by plugging in the x values into the parent function.
X Y
2 4
1 1
0 0
-1 1
-2 4
Once these points are plotted you can start determining what are the transformations. Find the difference between the parent function and f(x) = (x + 4)^2 + 2 by looking below.
Vertical Shifts:
f(x) + c moves up,
f(x) - c moves down.
Horizontal Shifts:
f(x + c) moves left,
f(x - c) moves right.
The parent function has to be transformed left 4 and up 2. In order to do this shift each point from earlier left 4 and then up 2. In conclusion you will have two functions graphed (parent function and the transformed function).

Which brand should the store eliminate?
Answers
Answer:
Brand D has the highest return rate so they should eliminate that one.
Step-by-step explanation:
brand A - .0481
brand B - .0307
Brand C - .0410
Brand D - .0788
The store should eliminate Brand D.
What is return rate?Return rate refers to the percentage of products or items that are returned to a seller or retailer by customers.
It is calculated by dividing the number of items returned by the total number of items sold and multiplying by 100 to get a percentage.
We have,
To determine which brand to eliminate, we need to calculate the return rate for each brand.
The return rate is the ratio of the number of items returned to the total number of items sold.
The brand with the highest return rate is the most likely to be returned and should be eliminated.
Using the data given in the table, we can calculate the return rate for each brand as follows:
Brand A: 22/457 = 0.048
Brand B: 10/328 = 0.031
Brand C: 21/511 = 0.041
Brand D: 19/241 = 0.079
Therefore,
Brand D has the highest return rate at 0.079 or 7.9%, which means it is the most likely to be returned.
The store should eliminate Brand D.

What is the value of x? Pls help
Answers
Answer:
x=20
Step-by-step explanation:
ok so that is a pentagon and if you didnt know all of the angles in a pentagon add up to equal 540
so we setup an equation which would be
7x+4x+5+4x+10+5x-5+6x+10=540 and now we just solve for x
step 1 combine like terms
7x+4x=11x
11x+4x=15x
15x+5x=20x
20x+6x=26x
5+10=15
15-5=10
10+10=20
now we have
20+26x=540
step 2 subtract each side by 20
20-20 cancels out
540-20=520
now we have 26x=540
the final step is to divide each side by 26
26/26 cancels out
540/26=20
x=20
hope this helps :D

Step-by-step explanation:
First, eliminate choice B b/c the max is 28, not 26.
Next, lets find the median.
(12+18+20+20+24+26+28+28) = (20+24)/2 = 22
That leaves us with only A & C as a possible answer.
Q1 = The median of the first half of the data (12, 18, 20, 20)
Q1 = (18+20) / 2 = 19
A & C have the same Q1 values, so we need to compare Q3 values.
Q3 = The median of the second half of the data (24, 26, 28, 28)
Q3 = (26+28) / 2 = 27
The Correct Answer is C b/c A had a different Q3 value.

Step-by-step explanation:
The two angles are set within a right angle, so the sum of the two angles must equal 90 degrees. These two angles are known as complementary angles. Simply subtract 90 from 63 to get the missing angle measure of 27 degrees.
If this helped, a brainliest answer would be greatly appreciated!
if that is a 90 degree angles and it tells you that the bigger angle on the bottom is 63 degrees than the top angle would be 27 degrees.

Plot the zeros of this function:
f(x) = (x – 1)(x – 7).
Answers
Answer:
Zeros of the given function are x = 1, 7
Step-by-step explanation:
Given function is,
f(x) = (x - 1)(x - 7)
For zeros of the function,
f(x) = 0
(x - 1)(x - 7) = 0
(x - 1) = 0
x = 1
(x - 7) = 0
x = 7
Therefore, zeros of the given function are x = 1, 7
We can find the zeros by suing a graphing tool.
