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
First set up the equation 12x-7=4x+9
Get all the x's on one side and number on one side so you have 8x= 16
You get X=2
Answer:
Use the website Desmos
Step-by-step explanation:
Type it in on the right side of the screen to see the graph,
make sure to understand why it is doing that though, its useless to be in school if you dont want to learn. and if you dont learn, good luck in life.
Answer:
A. JKH and IHK
Step-by-step explanation:
alternate interior angles are formed when two parallel (or non-parallel but parallel in this case) are intersected by a transversal (line FM)
Since they're both already in terms of y, you can just set them equal to each other.
4x = 1/2x + 280
3.5x = 280
x = 80
So 80 would be the amount he needs to sell to make the cost and revenue equal each other.
