We are given the function
F(x) = 9 sinx + cot x
We need to take the first derivative of the given function so,
F' (x) = 9 cos x - csc² x
Next, we equate the first derivative of the function to 0 and solve for the values of x
0 = 9 cos x - csc² x
Solving for x
x = 2.04
Picking out an arbitrary value between 2.04 and π, say 3 and substituting in F(x)
F(3) = 9 sin 3 + cot 3 = 19.55
Therefore, the interval where the function is increasing is from 2.04 to π
Consequently, the interval where the function is decreasing is from -π to 2.04<span />
Step-by-step explanation:
Repeated Addition:
3/4 +3/4 +3/4 +3/4 = 12/4 = 3
The denomenator will stay the same (4). So all you need to do is add the numerator (top. number in the fracton, 3)
It is the same logic as a basic multiplication problem using reapeted additon
(see example below:)
10 * 5 = 50
10 +10 +10 +10 +10 = 50
Multiplication:
4 * 3/4 = 12/4 = 3
You should not multiply the denomerator. You should only multiply the numerator. So you multiply 4 times 3 and get 12. So, you should get 12/4.
I apologize for my bad spelling.
17 because Caronline is twice as old as Sarah which makes Sarah 14 and Jacob is 3 years older then Sarah
