ABC is dilated by a factor of to produce A'B'C'.
What is AB, the length of AB after the dilation? What is the measure of <A?
Answers
Answer: The answer is A
Since we are dilating by 1/2 the image must get smaller. Now that we know that you can divide the side lengths by 2 (or multiply by 1/2) to get A'B' equals 17. Angles measures don't change during dilation because it only affects the side lengths, so angle A' is still 28 degrees
Hope this helped you!

A

Perimeter of ABCD = 56 units
Perimeter of WXYZ = 140 units
Step-by-step explanation:
To find the perimeter of ABCD, find the sum of all sides
18 + 18 + 10 + 10 = 56
To find the side lengths of WXYZ, use the equation: [tex]\frac{image}{pre-image}[/tex]
45/18 = 2.5
You can also cross multiply to find the missing side lengths, but I'll show you this other way...
Multiply the pre-image side lengths by 2.5
18 × 2.5 = 45
10 × 2.5 = 25
45 and 25 of the new side length of WXYZ
To find the perimeter of WXYZ, find the sum of all sides.
45 + 45 + 25 + 25 = 140
WX = 45, XY = 25, YZ = 45, ZW = 25

In order to add the two values together, you must find the least common multiple for the denominators. The denominators are 8 and 4, and the least common multiple of 8 and 4 is 8. Because you have to multiply 4 by 2 to get 8, you must also multiply 3 by 2 to get 6. This will give you 6/8.

g(n) = 18 - 4n
Step-by-step explanation:
Given the recursive formula
g(n) = g(n - 1) - 4 with common difference d = - 4 and g(1) = 14
The explicit formula for an arithmetic sequence is
g(n) = g(1) + (n - 1)d , then
g(n) = 14 - 4(n - 1)
= 14 - 4n + 4
= 18 - 4n

Mr. Gray's quiz was normally distributed with a mean of 25 and a standard deviation of 10. Find z-scores for each of the following data values
a. 40
b. 27
c. 6
Answers
Answer:
a. 1.5
b. 0.2
c -1.9
Step-by-step explanation:
The computation of the z scores of each of the following data values are as follows:
As we know that
z = (data values - mean)÷ standard deviation
Now
a. The z value is
= (40 - 25) ÷ (10)
= 1.5
b. The z value is
= (27 - 25) ÷ 10
= 0.2
c. The z value is
= (6 - 25) ÷ 10
= -1.9

To get rid of a radical we multiply the radical by itself, so we multiply [tex]\frac{3}{\sqrt{2}} by \frac{\sqrt{2}}{\sqrt{2}}[/tex]
to get [tex]\frac{3\sqrt{2}}{2}[/tex].
#3:
[tex]\sqrt\frac{2}{5}[/tex] is the same as [tex]\frac{\sqrt{2}}{\sqrt{5}}[/tex] so we multiply by [tex]\frac{\sqrt{5}}{\sqrt{5}}[/tex] so we get [tex]\frac{\sqrt{10}}{5}[/tex].

. Jumbo bought 5 books, each with a whole-number price.
The mean price of the books was $10. The median price was $8.
The most expensive book cost $15 and the cheapest cost $6.
What are the possible prices for the other books?
Answers
Mean is average. Multiply total books by the mean to find the total cost:
5x 10 = $50 total.
Subtract the highest and lowest prices to find the total of the remaining 3 books.
50 - 15-6 = 29
The median price was 8, this is the middle number, subtract 8 from 29 to get the cost of the last 2 books:
29-8 =21
Now you need a price lower than the median but higher than the lowest cost so that has to be 7
Subtract 7 from 21 to get the cost of the last book 21-7 = 14
The price of the remaining books is $7 and $14
An isosceles triangle has an angle that measures 134°. Which other angles could be in that isosceles triangle?
Answers
Answer:
[tex]23^{o}[/tex] and [tex]23^{o}[/tex]
Step-by-step explanation:
An isosceles triangle has two of its sides and angles to be equal. Let each of the unknown equal angles be represented by x. Since one of its angles measures 134°, then;
x + x + 134° = [tex]180^{o}[/tex]
2x + 134° = [tex]180^{o}[/tex]
2x = [tex]180^{o}[/tex] - 134°
= 46
x = [tex]\frac{46}{2}[/tex]
= [tex]23^{o}[/tex]
x = [tex]23^{o}[/tex]
The other angles that could be in the isosceles triangle are [tex]23^{o}[/tex] and [tex]23^{o}[/tex].
