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:
3 - 11x
x is "a number".
so, the request is to multiply it by 11 and subtract the result from 3.
I would divide 120 by 6 and get 20
That would mean Amanda is older because one-half would be 150%
Answer:
hope this helps!
Step-by-step explanation:
From y(t) = −16t^2 − 3t + 300 find at what time the fertilizer hits the ground (has height 0)
0 = −16t^2 − 3t + 300
Using the quadratic formula (minus b plus or minus the square root of b squared minus 2 a c over 2 a) you get
t = 4.237 seconds
So the horizontal distance is 85t = 85 * 4.237 = 360.145 feet
