39.65 is the approximate value of arccos0.77
The answer is c, 2.To find this, look on the graph for a point with the y value of -1. (2,-1) is the solution.
The value of the derivative of functions h'(6) as requested in the task content is; 55.
<h3>What is the value of h'(6)?</h3>
Since it follows from the task content that the function h(x)=4f(x)+5g(x)+1.
Hence, the derivative of h(x) can be evaluated as;
h'(x)=4f'(x)+5g'(x)
On this note, by substitution, it follows that;
h'(6)=4(5)+5(7)
h'(6) = 55.

It's D.
Step-by-step explanation:
Convert each number to decimal format.
It is option D , if we convert as above we get
7.36799, 7.36666.., 7.363636.., 7.33333..
1km is 1000 m
1000m+125m-375m=750m
