a) Rectangles are similar
b) 1 : 9
c) No volume
Step-by-step explanation:
Step 1 :
Given
The length and width of rectangle1 is x and y
The length and width of rectangle2 is kx and ky
Step 2 :
a)
2 rectangles are similar when the sides of the rectangles are proportional
Since here we have the sides of rectangle 2 obtained by multiplying each side of the first rectangle by a non zero constant term , the 2 given rectangles are proportional
Step 3 :
b)
Area of rectangle1 is x * y
Area of rectangle is 3x * 3y = 9xy (given k = 3)
Ratio of the areas is xy : 9 xy = 1 : 9
Step 3 :
Given k = 2
There is no volume for a 2 dimensional figure
Its 2 11/12 hope it helps
Answer:
A
Step-by-step explanation:
Calculate the distance (d) using the distance formula
d = √ (x₂ - x₁ )² + (y₂ - y₁ )²
with (x₁, y₁ ) = (5, - 3) and (x₂, y₂ ) = (0, 2)
d = ![\sqrt{(0-5)^2+(2+3)^2}](https://tex.z-dn.net/?f=%5Csqrt%7B%280-5%29%5E2%2B%282%2B3%29%5E2%7D)
= ![\sqrt{(-5)^2+5^2}](https://tex.z-dn.net/?f=%5Csqrt%7B%28-5%29%5E2%2B5%5E2%7D)
= ![\sqrt{25+25}](https://tex.z-dn.net/?f=%5Csqrt%7B25%2B25%7D)
=
=
= 5![\sqrt{2}](https://tex.z-dn.net/?f=%5Csqrt%7B2%7D)
