How much interest if you borrow 3500 at a rate of 6 percent for 10 years?

User Avatar

Asked by Wiki User

Under normal commercial practice. use compound interest /

I(n) = I(o)[ 1 + r/100]^(n)

Hene

I(10) = 3500[1 + 6/100]^(10)

I(10) = 3500[ 1.06^(10))

I(10) = 3500 *1.790847697

I(10) = 6267.966938

I(10) ~ 6267.97

Amount of interest paid is 6267.07 = 3500 = 2767.97 is the amount of interest paid .

What is the vertex of the parbola y equals x2-4x plus 12?

User Avatar

Asked by Wiki User

Differentiate and equate to zero

Hence

y = x^2 + 4x - 12

dy/dx = 2x + 4 = 0

2x = -4

x = -2

Hence

y = (-2)^2 +4(-2) - 12

y = 4 - 8 - 12

y = - 16

Hence the vertex is (x,y,) = ( -2,-16)
