Question 4
If f(x) = e^x then In (f' (2)) =

I need an explanation on how to solve.

A

Step-by-step explanation:

We are given the function:

And we want to determine the value of:

First, find f'. We can take the derivative of both sides with respect to x:

Find f'(2):

We can take the natural logarith of both sides:

Simplify. In conclusion:

Our answer is A.

(sin 42)/31. = sinx)/37

sinx = 37 (sin42)/31

= 37× 0.66/31 = 0.787

x= 51.9

other angle opposite to y = 180-51.9-42

= 180- 93.9 =86.1

so

sin42)/31 = sin 86.1)/y

0.021 = 0.997 /y

y= 0.997/0.021 =47.47
