Answer: (a) e ^ -3x (b)e^-3x
Step-by-step explanation:
I suggest the equation is:
d/dx[integral (e^-3t) dt
First we integrate e^-3tdt
Integral(e ^ -3t dt) as shown in attachment and then we differentiate the result as shown in the attachment.
(b) to differentiate the integral let x = t, and substitute into the expression.
Therefore dx = dt
Hence, d/dx[integral (e ^-3x dx)] = e^-3x
Answer:
3
Step-by-step explanation:
2x^9 = 1
3x^6 = 2
- x - 20 = 3
Answer:
7.5 pounds
Step-by-step explanation:
multiply by 3.
3x+3y=30
2x+3y=22.5.
x=7.5.
7.5+2.5=10.
7.5 pounds of walnuts, 2.5 pounds of raisins.
Hope this helps :D
