d/dx cos^2(5x^3)
= d/dx [cos(5x^3)]^2
= 2[cos(5x^3)]
= - 2[cos(5x^3)] * sin(5x^3)
= - 2[cos(5x^3)] * sin(5x^3) * 15x^2
= - 30[cos(5x^3)] * sin(5x^3) * x^2
Explanation:
d/dx x^n = nx^(n - 1)
d/dx cos x = - sin x
Chain rule:
d/dx f(g(...w(x))) = f’(g(...w(x))) * g’(...w(x)) * ... * w’(x)
Hello!
To find the area of a circle you do
Where r stands for radius.
The radius is just half the diameter
So you put that into a calculator and get 113.1
Hope this helps!
Line them up on top of each other so it would be 30,261 so you were close but you have to line them up correctly
Answer:
1. 5 less than three times a number, n?
=3n-5
2 . Y multipled by 3.2 and then 12 added to the product ?
=3.2y+12
3. Eight more than four times a number , n ?
=4n+8
4. 8(m+1) =8m+8
Answer:
3:37
Step-by-step explanation:
Since it started 18 minutes before it ended, you need to subtract 18 minutes from 3:55 which makes the starting time 3:37 P.M
