Subtraction is the operation that you should is to solve this problem
6.75 x 14 will get you 94.5 and if you add another 6.75 you will go to high for your goal so that answer is 14
Answer:
Step-by-step explanation:
Given that there is a function of x,

Let us find first and second derivative for f(x)

When f'(x) =0 we have tanx = 1 and hence
a) f'(x) >0 for I and III quadrant
Hence increasing in 
and decreasing in 


Hence f has a maxima at x = pi/4 and minima at x = 3pi/4
b) Maximum value = 
Minimum value = 
c)
f"(x) =0 gives tanx =-1

are points of inflection.
concave up in (3pi/4,7pi/4)
and concave down in (0,3pi/4)U(7pi/4,2pi)

40 feet make 13 and 1/3 yards
So that is 13 yards to nearest </span>
