Answer:
3 and 4
Step-by-step explanation:
A dilation is a transformation that produces an image that is the same shape as the original, but is a different size so here reducing a photograph to half its dimensions and enlarging a photograph to double the dimensions is dilation.
=> For dilation, we use a certain scale factor
=> In the 3rd option, scale factor is 1/2
=> In the 4th option, scale factor is 2.
Answer:
528
Step-by-step explanation:
Question: 16 + 
* 2 ÷ 16
Work:
= 64
2/16 = 0.125
64/0.125 = 512
512 + 16 = 528
Divide 30 by 5. For example 30/5= 6. 5 lots of 6 make up 30, so that means 1/5 th of 30 is 6.
C) 1 b =-2. D) 7 f(-2) = 3(-8) - 2. -5 x=6
y. 4(y + 1) = x. If (x, y) is the solution to
the system of equations.
Answer:
area= 452.39
circumference= 75.40
Step-by-step explanation:
circumference is equal to 2 * pi * r
area is equal to pi * r^2
circumference = 2 * pi * 12 = 75.40
area = pi * 12^2 = 452.39
hope this helps!
