Time = 2

Simple interest = 10.20

To find the annual interest rate;

Mathematically, simple interest is calculated using this formula;

Where;

Substituting into the equation, we have;

Cross-multiplying, we have;

R = 1.2%

Therefore, the annual interest rate is 1.2 percent.

what i would say the best answer is a. 40.5

c.

step-by-step explanation:

substitution for (0,1)

y=x^2+4x+1

1=0^2+4(x)0+1

1=0+4(x)0+1

1=4(x)0+1

1=0+1

1=1

substitution for (-3,-2)

y=x+1

-2=-3+1

-2=-2
