Answer:

216°

Step-by-step explanation:

The ratio of the sum of smallest and largest to the total of all angles is ...

(9 +15)/(9 +10 +12 +14 +15) = 24/60 = 0.4

The total of all angles in an n-gon is 180°(n -2), so the total of all angles in a pentagon is ...

180°(5 -2) = 540°

Then the sum of smallest and largest angles is ...

0.4(540°) = 216°

The function f(x) = 3x² + 12x +11 can be written in

Viktor [21]

Answer:

3) f(x) = 3(x + 2)^2 - 1.

Step-by-step explanation:

f(x) = 3x² + 12x +11

f(x) = 3(x^2 + 4x) + 11 Completing the square:

f(x) = 3[(x + 2)^2 - 4] + 11

f(x) = 3(x + 2)^2 -+3*-4 + 11

f(x) = 3(x + 2)^2 - 12 + 11

f(x) = 3(x + 2)^2 - 1.

A mother invests $7000 in a bank account at the time of her daughter's birth. The interest is 18) compounded quarterly at a rate

Alex

well, from birth to your twentieth birthday that'll just be 20 years, so

$~~~~~~ \textit{Compound Interest Earned Amount} \\\\ A=P\left(1+\frac{r}{n}\right)^{nt} \quad \begin{cases} A=\textit{accumulated amount}\\ P=\textit{original amount deposited}\dotfill &\$7000\\ r=rate\to 8\%\to \frac{8}{100}\dotfill &0.08\\ n= \begin{array}{llll} \textit{times it compounds per year}\\ \textit{quarterly, thus four} \end{array}\dotfill &4\\ t=years\dotfill &20 \end{cases} \\\\\\ A=7000\left(1+\frac{0.08}{4}\right)^{4\cdot 20}\implies A=7000(1.02)^{80}\implies A\approx 34128.07$
