Answer:

Equilateral Triangles are always regular polygons.

Step-by-step explanation:

This is because all of the interior angles are the same(60 degrees). Regular polygons have the same interior angles. For instance, a pentagons interior angle is 108 degrees.

Dave is considering two loans. Loan U has a nominal interest rate of 9. 97%, and Loan V has a nominal interest rate of 10. 16%.

Vsevolod [243]

Loan U will have a lower effective interest rate, and 0.0713 lower percentage points lower than Loan V and it can be determined by using the rate of interest formula.

Given that,

Dave is considering two loans.

Loan U has a nominal interest rate of 9.97%, and Loan V has a nominal interest rate of 10.16%.

If Loan U is compounded daily and Loan V is compounded quarterly.

We have to determine,

Which loan will have the lower effective interest rate, and how much lower will it be?

According to the question,

<h2>Effective Interest Rate;</h2>

The effective interest rate is determined by the formula;

$= \left(1+\dfrac{r}{t} \right )^t$

Loan U has a nominal interest rate of 9.97%,

Loan U is compounded daily,

Then,

The effective annual multiplier for loan U is,

$= \left(1+\dfrac{0.997}{365}\right)^{365}\\\\= (1+0.0027)^{365}\\\\= (1.0027)^{365}\\\\= 1.104824$

And Loan V has a nominal interest rate of 10.16%,

and Loan V is compounded quarterly.

Then,

$= \left(1+\dfrac{0.1016}{4}\right)^{4}\\\\= (1+0.0254)^{365}\\\\= (1.0254)^{365}\\\\= 1.105537$

Therefore,

Loan V has a higher effective rate by,

$=1.105537 -1.104824 \\\\= 0.000713 \\\\= 0.0713%$

Hence, Loan U will have a lower effective interest rate, and 0.0713 lower percentage points lower than Loan V.

What is the volume of the shape?

expeople1 [14]

Volume of the bottom rectangle:

12 x 4.5 x 5.5 = 297 cubic cm

Volume of triangle:

1/2 x 12 x 5 = 30 x 4.5 = 135 cubic cm

Total volume = 297 + 135 = 432 cubic cm
