Aprincipal of $3900 is invested at 7.25% interest, compounded annually . how much will the investment be worth after 11 years?

Total after 11 years: $46,010.25

Just interest after 11 years: $3,110.25

Step-by-step explanation:

Multiply 3900 by 0.0725, which is the decimal version of 7.25%

3900×0.0725=282.75

Add that interest (which is interest for one year) to the 3900. You get 4182.75. That is one year of the principle and interest combined.

Multiply this by 11.

11×4182.75= 46,010.25

If you need to find just the amount of interest over 11 years, multiply the 282.75, which we found earlier, by 11.

282.75×11=3110.25

a; x = 0.5

step-by-step explanation:

-10x = -5

x = 0.5

step-by-step explanation:

f(x)=2x^2 -1 

translation is a function transformation that transform the function in a way of translating. by translating the function its graph is moved  up an down. moving the function f(x) 2 units to the left will be the new function g(x) with the equation: g(x)=f(x+2)=2(x+2)^2 -1
