Pentagonal prism B is the image of pentagonal prism A after dilation by a scale factor of \frac{1}{5}

Mathematics

Both prisms would have different areas, and the surface area of the pentagonal prism A, the preimage is 125 cm^2

<h3>How to determine the surface area of the prism A?</h3>

The given parameters are:

  • Scale factor from A to B, k = 1/5
  • Surface area of B = 5

The relationship between the surface areas of both prisms is represented as:

B = A * k^2

So, we have:

5 = A * (1/5)^2

Evaluate

5 = A * 1/25

Multiply both sides by 25

A = 125

Hence, the surface area of the pentagonal prism A, the preimage is 125 cm^2

use the distance formula to find the distance between the two points. (0, -2) and (9, 10) give the exact length (leave in radica
kkurt [141]

Answer:

15 units

Step-by-step explanation:

Calculate the distance d using the distance formula

d = \sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2    }

with (x₁, y₁ ) = (0, - 2) and (x₂, y₂ ) = (9, 10)

d = \sqrt{(9-0)^2+(10+2)^2}

   = \sqrt{9^2+12^2}

   = \sqrt{81+144}

   = \sqrt{225}

   = 15

How many 1/3 inch are in 3/4 inch?
AnnZ [28]

Answer:

2, 1/3 inches in 3/4

basically you multiply the denominator to match the other problem so 1/3 becomes 4/12 and 3/4 becomes 9/12

so there are 2 1/3 inches in 3/4, this is a sort of rough explanation I reccomend going on Khan Academy and looking for something to help you there
