Given: A = {a, e, i, o, u}, B = {a, l, g, e, b, r}, C = {m, y, t, h}, A ∩ C is
Assoli18 [71]
the answer is { } "an empty set or phi"
- because there isn't any common elements between the two sets
The scale factor which used to perform the dilation was 0.4
Step-by-step explanation:
If point (x , y) is dilated about the origin by a scale factor k, then
- Its image is point (kx , ky)
- If k > 1, then kx > x and ky > y
- If 0 < k < 1, then kx < x and ky < y
∵ Δ RST is dilated about the origin O to create Δ R'S'T'
- Assume that the scale factor is k
∵ Point R is (3 , 9)
∴ x = 3 and y = 9
∵ Point R' is (1.2 , 3.6)
∴ kx = 1.2 and ky = 3.6
∵ x = 3 and kx = 1.2
- Substitute x in kx to find k
∴ k(3) = 1.2
∴ 3k = 1.2
- Divide both sides by 3
∴ k = 0.4
To check your answer use the y-coordinates of R and R' to find k
∵ y = 9 and ky = 3.6
- Substitute the value of y in ky to find k
∵ k(9) = 3.6
∴ 9k = 3.6
- Divide both sides by 9
∴ k = 0.4
∴ The scale factor is 0.4
The scale factor which used to perform the dilation was 0.4

Neither are correct. if you are to research both of them you will notice neither are correct. translations are just a mirror of eachother and same for the other one. these are not mirrors of eachother
Answer:
7161 km³
Step-by-step explanation:
28²+b²=32.5²
784+b²=1056.25
b²=1056.25-784
b²=272.25
b=√272.25
b=16.5
1/2x28x16.5x31=7161
$90
because if 1 body equals 30 each and she has 3 body’s add 30 3 times 30+30=60+30=90
