1. Problem Description

The problem states that there are nine dominos numbered 0 to

8. Domino 0 is 3.00 inches tall. Each subsequent domino is 10% taller than the one before it. The goal is to find the height of domino

8.

2. Solution Steps

The height of each domino can be calculated using the formula for compound interest:
Heightn=Height0(1+r)nHeight_n = Height_0 * (1 + r)^n
where:
HeightnHeight_n is the height of domino nn.
Height0Height_0 is the height of domino 0, which is 3.00 inches.
rr is the rate of increase, which is 10% or 0.

0. $n$ is the domino number.

In this case, we want to find the height of domino 8, so n=8n = 8.
Height8=3.00(1+0.10)8Height_8 = 3.00 * (1 + 0.10)^8
Height8=3.00(1.10)8Height_8 = 3.00 * (1.10)^8
Height8=3.002.14358881Height_8 = 3.00 * 2.14358881
Height8=6.43076643Height_8 = 6.43076643
Rounding to two decimal places, we get Height8=6.43Height_8 = 6.43 inches.

3. Final Answer

The height of domino #8 is 6.43 inches.
