Answer:
Step-by-step explanation:
We have the function:
![h(x)=f[f(x)]](https://tex.z-dn.net/?f=h%28x%29%3Df%5Bf%28x%29%5D)
And we want to find:
So, we will differentiate function <em>h</em>. By the chain rule, this yields:
![h^\prime(x)=f^\prime[f(x)]\cdot f^\prime(x)](https://tex.z-dn.net/?f=h%5E%5Cprime%28x%29%3Df%5E%5Cprime%5Bf%28x%29%5D%5Ccdot%20f%5E%5Cprime%28x%29)
Then it follows that:
![h^\prime(1)=f^\prime[f(1)]\cdot f^\prime(1)](https://tex.z-dn.net/?f=h%5E%5Cprime%281%29%3Df%5E%5Cprime%5Bf%281%29%5D%5Ccdot%20f%5E%5Cprime%281%29)
Using the table, we acquire:
And using the table again, we acquire:
Evaluate. Hence:
Answer:
The slope of one of the guy wires is m=0.7
Step-by-step explanation:
Divide the vertical distance of the guy wire by the horizontal distance of the guy wire to find the slope of one of the guy wire.
We have
d = 100ft ----- horizontal distance
h = 70ft ------- vertical distance
Then,
m = h/d
Put the values in the given formula:
m = 70/100
m = 0.7
Thus the slope of one of the guy wires is m=0.7
