The equation is false so no solution.
Simplify 8/5 * -6 to -48/5
Move the negative sign to the left
Simplify brackets
Since 48/5 = -54 its false so no answer
Make a ratio, then cross multiply.
4/30=x/48
30x=4x48
30x=192
x=6.4
X+

=12
5x=36
x=7.2
So, the triangular entrance to the tent is
7.2 feet tall and
4.8 feet wide
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
