2520°

Step-by-step explanation:

The sum of the angles in any triangle is 180°

shape. sides. triangles. sum int angles.

triangle. 180×1=180°

quad. 180×2=360°

pentagon. 180×3=540°

n-sides. n( n−2) 180(n−2)

16-sides. 180×14=2520°

The number of books donated to a library is increasing by 25% each month. Initially, there were 80 books donated to the library.

Answer: There would be 745 books at the end of month 10.

Step-by-step explanation:

Since we have given that

Number of books initially = 80

Rate of growth = 25% = 0.25

t = 10 months

We need to find the number of books that are expected at the end of month 10.

As we know the formula for "Compound interest":

$A=P(1+\dfrac{r}{100})^t\\\\A=80(1+\dfrac{25}{100})^{10}\\\\A=80(1+0.25)^{10}\\\\A=80(1.25)^{10}\\\\A=745.05$

Hence, there would be 745 books at the end of month 10.

The graph is that of a fourth-degree polynomial function. Which of the following correctly shows three factors of the function?

Aliun [14]

Observe that the roots of polynomial are $-3,2,5$

We have a polynomial in a factored form,

$(x+3)(x-2)(x-5)$

If you substitute x for any of $-3,2,5$ the product will always equal to zero that is these numbers are roots of polynomial.

Hope this helps :)
