Step-by-step explanation:
f (-3)
f= x value
answer= y value
The answer is actually -3 because the y value for x is -3
Is it a written response or a multiple chose question?
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:
25
Step-by-step explanation:
<u>By </u><u>Thales </u><u>Theorem</u><u> </u><u>:</u><u>-</u><u> </u>
- 40/24 = x/15
- x = 15 * 40/24
- x = 25
<u>Hence</u><u> the</u><u> </u><u>Va</u><u>l</u><u>ue </u><u>of</u><u> </u><u>x </u><u>is </u><u>2</u><u>5</u><u> </u><u>.</u>
