How do you integrate 7xe^-5x²?

1 answer:

3 0

Making assumptions about where parentheses should be,
Let u = -7x 
du = -7dx 
dv = e^(2x) dx 
v = e^(2x)/2 
∫ -7xe^(2x) dx = 
-7xe^(2x)/2 - ∫ e^(2x)/2 (-7) dx = 
-7xe^(2x)/2 + 7e^(2x)/4 + c

Principle 1600, rate 6 ,time 2.5 years find CI

shutvik [7]

Answer:

C.I = $251.2

Step-by-step explanation:

P = Principal amount = 1600

r = rate of annual interest = 6%

n = period / no. of years = 2.5 years

C.I = (P* (1+r^n))-P

C.I = (1600*(1+0.06)^2.5))-1600

C.I = (1600*(1.06^2.5))-1600

C.I = (1600*1.157)-1600

C.I = 1851.2-1600

C.I = 251.2
