Answer:
2x(sinx^2 + x^2cosx^2).
Step-by-step explanation:
We use the product rule:
If u and v are functions of x then:-
d(uv)/dx = u dv/dx + v du/dx
So:
d(x^2 sinx^2)dx
= x^2 * d(sinx^2)/dx + sinx^2 * d(x^2)/dx
= x^2 * 2xcosx^2 + sinx^2 * 2x
= 2x^3cosx^2 + 2xsinx^2
= 2x(sinx^2 + x^2cosx^2).
Answer:
33297327
Step-by-step explanation:
(15267 * 15267) ÷ 7
= 15267 * 15267
= 233081289 ÷ 7
= 33297327
Hope this helps! :)
Answer:
x=30 , <HFC= 120 , <DBG=60
Step-by-step explanation:
First when I take a look at these types of problems I always make sure to look around and see if there is anything that can help me.
A very key thing to remember is that all angles that are on a line will = 180
So looking at the angles and just normal geometry rules you can know that 2x+4x=180 cause the inner angles add up to 180.
So then if 6x=180 then divide by 6 to get 30 for finding x!
Answer:
60%
Step-by-step explanation:
1/5 equals 20 % and thus 3/5 is 20 % multiplied by 3 so 60 %
Answer:
X=2
Step-by-step explanation:
first combine like terms
subtract the x
add 5
lastly divide by 7
