65:100 because there are 65 girls and then 65 girls + 35 boys = 100 total students
Answer:
-2x cos x + 2 sin x + C
Step-by-step explanation:
∫ (2x sin x) dx
If u = 2x, then du = 2 dx.
If dv = sin dx, then v = -cos x.
∫ u dv = uv − ∫ v du
= 2x (-cos x) − ∫ (-cos x) (2 dx)
= -2x cos x + 2 ∫ cos x dx
= -2x cos x + 2 sin x + C
Answer:
expression:3(1/2)+1 ; 2 1/2
Step-by-step explanation:
Combine 3 and 1/2
3+1/2
=5/2
Simplify the expression.
=5/2
=2
Answer:
what is the question? I do not get what the question is.
Fifteen is expressed as 15/1, so you flip the numerator and denominator to get 1/15.
