Answer:
Height = 17.31821 feet
Step-by-step explanation:
<u><em>Explanation</em></u>
<u><em>From graph</em></u>
Given angle θ = 6.5° and a = 152 feet
we need to find the height (h)
By using the tangent rule
Cross multiplication , we get
b = 152 × tan 6.5°
b = 152 × 0.113935
b = 17.31821 feet
Height = 17.31821 feet
You need to find the values of x that correspond to the given values of f(x). That is, you need to solve for x:
.. y = 7x -2.7
.. y +2.7 = 7x
.. x = (y +2.7)/7
You are given y values of {14.1, 30.9, 41.4, 58.9, 68}. The corresponding x values are {2.4, 4.8, 6.3, 8.8, 10.1}, corresponding to selection C.
_____
Since the first number in each choice is different, you only need to evaluate f(x) for those numbers to see which gives the correct result. Only the 3rd one (2.4) give f(2.4) = 14.1, the correct answer.
