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
I’m a bit confused by the choices you have been given. Are there any other options? If not, I would choose (5.3,9.8) as 9.8 is correct
Answer:
27.4 km
Step-by-step explanation:
vertical line- y
17 km/y= tan 54
y= 17/tan 54= 25.2 km
25.2/x= cos 23
x= 25.2/cos 23= 27.4 km
The answer is 940 good luck and I hope I’m right
Answer:
Step-by-step explanation:step 1: open the brackets
_14+7m -5 - m ( sign changes as minus x plus = minis)
Step 2; collect like terms
-14-5+7m+ m
-19+8m
