Step-by-step explanation:
A1 = 9
r = 2/3
An = ar^{n - 1}
An = 9.(2/3)^{n - 1}
Option → C
Answer:
30.5 ft squared
Step-by-step explanation:
First, find the area and shape. If it is a square then you want to divide by four since all sides are equal. So divide 122 by 4 and you get the answer.

Answer:
h(2)=-18
Step-by-step explanation:
![h(x)=-x^3-2x^2-3x+4\\Substituting\ x=2,\\h(2)=-(2)^3-2(2)^2-3(2)+4\\h(2)=-(8)-2*4-6+4\\h(2)=-8-8-6+4\\h(2)=-22+4\\h(2)=-18](https://tex.z-dn.net/?f=h%28x%29%3D-x%5E3-2x%5E2-3x%2B4%5C%5CSubstituting%5C%20x%3D2%2C%5C%5Ch%282%29%3D-%282%29%5E3-2%282%29%5E2-3%282%29%2B4%5C%5Ch%282%29%3D-%288%29-2%2A4-6%2B4%5C%5Ch%282%29%3D-8-8-6%2B4%5C%5Ch%282%29%3D-22%2B4%5C%5Ch%282%29%3D-18)
Answer:
A) 440.44 units³
B) similar figures
C) 1486.485 units³
Step-by-step explanation:
Volume = ⅓× base area × height
= ⅓ × 110.11 × 12 = 440.44 units³
B) he doesn't have to make calculations again because the two pyramids are similar.
If the ratio of sides is given, he can find the other volume using:
(side1/side2)³ = volume1/volume2
(2/3)³ = 440.44/volume2
Volume2 = 440.44 × 27/8
Volume2 = 1486.485 units³
