Answer:
![8\sqrt{2}\ ft](https://tex.z-dn.net/?f=8%5Csqrt%7B2%7D%5C%20ft)
Step-by-step explanation:
see the attached figure to better understand the problem
Remember that
An isosceles triangle has two equal sides and two equal interior angles
In the isosceles triangle ABC
Applying the Pythagorean Theorem
Let
b ----> the length of the tents base
![9^2=7^2+(b/2)^2](https://tex.z-dn.net/?f=9%5E2%3D7%5E2%2B%28b%2F2%29%5E2)
![(b/2)^2=9^2-7^2](https://tex.z-dn.net/?f=%28b%2F2%29%5E2%3D9%5E2-7%5E2)
![(b^2/4)=32](https://tex.z-dn.net/?f=%28b%5E2%2F4%29%3D32)
![b^2=128\\\\b=\sqrt{128}\ ft](https://tex.z-dn.net/?f=b%5E2%3D128%5C%5C%5C%5Cb%3D%5Csqrt%7B128%7D%5C%20ft)
simplify
![b=8\sqrt{2}\ ft](https://tex.z-dn.net/?f=b%3D8%5Csqrt%7B2%7D%5C%20ft)
Using the given property, we conclude that:
f(4) = 8
<h3>
What is the value of f(4)?</h3>
We know that our function has the property:
5*f(x) = f(5*x)
Now, we also know that:
f(20) = 40
Notice that we can rewrite:
f(20) = f(5*4)
Using the above property, we know that:
f(20) = f(5*4) = 5*f(4) = 40
Using the last part:
5*f(4) = 40
f(4) = 40/5 = 8
f(4) = 8

It’s 4 because y is a variable plus any number in front of a variable makes it a coefficient
8 i believe hope it helps!
