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:
Therefore there revenue was $540,000.
Step-by-step explanation:
Let their total revenue last year be x
so
35% of x = $72,9000 - x
or, 35/100 × x = 729000 - x
or, 7x/20 = 729000-x
or, 7x = 20(729000-x)
or, 7x = 1458000- 20x
or, 7x + 20x = 14580000
or, 27x = 14580000
or, x = 14580000/27
so, x = $540,000
