If you borrow $500 from a credit union at 12% annual interest and $250 from a bank at 18% annual interest, what is the effective annual interest rate (that is, what single rate of interest on $750 would result in the same total amount of interest)? a. 10% b. 12% c. 14% d. 15%

14% that is option c is correct.

Step-by-step explanation:

We have been given that $500 from a credit union at 12% annual interest and $250 from a bank at 18% annual interest

That means  we will get

Since, we need to find the single rate of interest on 750

So, the required rate of interest will be:

That is 14%

Therefore, option c is correct

f(x) = x^3 -2x^2 -3x

x( x^2 -2x-3)

x( x^2 +x -3x -3)

x( x(x+1) -3(x+1))

x( x-3)( x+1)

so zeroes are 0, 3,-1

its (2) option

answer: evaluate the objective function at each vertex to determine which - and -values, if any, maximize or minimize the function. example: find the minimum value and maximum value of the objective function f ( x , y ) = 4 x + 5 y , subject to the following constraints
