Step-by-step explanation:
Answer:
681 feet
Step-by-step explanation:
Let x represent the distance between campsite and the base of the cliff.
We have been given that Haylee hikes to the top of a 120-foot vertical cliff. From the top of the cliff, the angle of depression to her campsite is 10∘. We are asked to find the distance between campsite and the base of the cliff.
We can see that angle of depression forms a right triangle with respect to ground, cliff and campsite.





Upon rounding to nearest foot, we will get:

Therefore, the campsite is 681 feet away from the base of the cliff.
we are given

we can use exponent formula

now, we can use this formula

we can add exponent
and we get




So, option-B.......Answer
The solutions to f(x) = 64 is x = 7 and x = –7.
Solution:
Given data:
and
To find the solutions when f(x) = 64.
Both are equations of f(x), so equate the given equations, we get

Subtract 15 from both sides of the equation.


49 can be written as 7².

Taking square root on both sides of the equation, we get
x = ±7
The solutions to f(x) = 64 is x = 7 and x = –7.
