When calculating accrued interest over several years that compounds annually, you must _____.

Darina [25.2K]

When calculating accrued interest over several years that compounds annually, you must calculate a new principle each year, adding the accrued interest from the previous year. At the beginning of the new interest period, all the accrued interest is added to the principal which forms a new principle figure that the interest is then counted on.

PLZ ans have mocks plz

Yanka [14]

Answer:

The table will be:

x |-2 | -1 | 0 | 1 | 2

y | 1 | 4 | 5 | 4 | 2

Step-by-step explanation:

The function is:

$y=5-x^{2}$

a) The x values of the table is:

x |-2 | -1 | 0 | 1 | 2

So, when x = -2, y will be:

$y(-2)=5-(-2)^{2}=5-4=1$

Doing the same with the other x values we have:

$y(-1)=5-(-1)^{2}=5-1=4$

$y(0)=5-(0)^{2}=5$

$y(1)=5-(1)^{2}=5-1=4$

$y(2)=5-(2)^{2}=5-4=1$

The table will be:

x |-2 | -1 | 0 | 1 | 2

y | 1 | 4 | 5 | 4 | 1

I hope it helps you!

#2: Solve the linear system below using the elimination method. Type your

MariettaO [177]

The given linear system is:

$\displaystyle \left \{ {{5x+7y=33} \atop {11x+7y=39}} \right.$

The question is asking to solve using elimination. When eliminating, you can either eliminate x or y. In this system, y is much easier to eliminate. The y variable in both equations are 7y. To eliminate, one of them has to be negative, so multiply one of the equations by -1.

I will be multiplying the second equation by -1.

$\displaystyle (11x + 7y = 39) \times -1 = -11x-7y=-39$

Rewrite the system:

$\displaystyle \left \{ {{5x+7y=33} \atop {-11x-7y=-39}} \right.$

Subtract:

$5x+7y=33\\-11x-7y=-39$

$5x-11x=33-39\\-6x=-6$

Lastly, you need to leave the variable x alone. The variable is currently -6x or -6 times x. To remove it, you need to do the opposite of it, which is dividing by -6.

$\displaystyle \frac{-6x}{-6} =\frac{-6}{-6}$
