If the path of the suspension cable between the towers is modeled by the function [tex]f(x)=\frac{1}{8}x^2-5x+52[/tex] and the first vertical tower is located at [tex]x=10[/tex] meters, determine the height at which the cable will be anchored on the first vertical tower.

When [tex]x=10[/tex] meters, the anchor will be placed on the tower at \_\_\_\_\_ meters. Round your answer to the nearest tenth if necessary.

Sure, let's determine the height at which the cable will be anchored on the first vertical tower using the given function and [tex]\(x\)[/tex] value.

Given:
[tex]\[ f(x) = \frac{1}{8}x^2 - 5x + 52 \][/tex]

We need to find the height when [tex]\( x = 10 \)[/tex] meters. Here's the detailed solution:

1. Substitute [tex]\( x = 10 \)[/tex] into the function:
[tex]\[ f(10) = \frac{1}{8}(10)^2 - 5(10) + 52 \][/tex]

2. Calculate [tex]\( (10)^2 \)[/tex]:
[tex]\[ (10)^2 = 100 \][/tex]

3. Multiply by [tex]\( \frac{1}{8} \)[/tex]:
[tex]\[ \frac{1}{8} \times 100 = 12.5 \][/tex]

4. Multiply [tex]\( -5 \)[/tex] by [tex]\( 10 \)[/tex]:
[tex]\[ -5 \times 10 = -50 \][/tex]

5. Add the results to the constant term [tex]\( 52 \)[/tex]:
[tex]\[ 12.5 - 50 + 52 \][/tex]

6. Simplify step-by-step:
- First, add [tex]\( 12.5 \)[/tex] and [tex]\( 52 \)[/tex]:
[tex]\[ 12.5 + 52 = 64.5 \][/tex]
- Then subtract [tex]\( 50 \)[/tex]:
[tex]\[ 64.5 - 50 = 14.5 \][/tex]

Thus, when [tex]\( x = 10 \)[/tex] meters, the height at which the cable will be anchored on the first vertical tower is [tex]\(\boxed{14.5}\)[/tex] meters.
