What is the annual compound interest rate for an investment account modeled by the function y=12⋅1.18t ?

The interest rate for the given investment is 18%.

Step-by-step explanation:

We are given that,

The function representing the investment model is, .

It is required to find the interest rate for the investment.

Since, the function can be re-written as,

i.e.

So, on comparing with the formula for compound interest i.e. , where 'r' is the interest rate.

We have that,

The interest rate for the given investment is 0.18 i.e. 18%.

there are many solutions.

step-by-step explanation:

step 1: simplify both sides of the equation.

4x+6=4x^2+10x−4

step 2: subtract 4x^2+10x-4 from both sides.

4x+6−(4x^2+10x−4)=4x^2+10x−4−(4x^2+10x−4)

−4x^2−6x+10=0

step 3: factor left side of equation.

−2(2x+5)(x−1)=0

step 4: set factors equal to 0.

x=-5/2 or x=1
