2x^3+5x^2-10 if x=-2

avanturin [10]

$▪▪▪▪▪▪▪▪▪▪▪▪▪ {\huge\mathfrak{Answer}}▪▪▪▪▪▪▪▪▪▪▪▪▪▪$

Let's evaluate :

${2x}^{3} + 5x {}^{2} - 10$

$2( - 2) {}^{ 3} + 5( - 2) {}^{2} - 10$

$(2 \times - 8) + (5 \times 4) - 10$

$- 16 + 20 - 10$

$- 26 + 20$

$- 6$

I put $500 in a saving account that earns 6% interest compounded semi-annually. How much interest will be in the account after 2

Nuetrik [128]

$\bf ~~~~~~ \textit{Compound Interest Earned Amount}
\\\\
A=P\left(1+\frac{r}{n}\right)^{nt}
\quad 
\begin{cases}
A=\textit{accumulated amount}\\
P=\textit{original amount deposited}\to &\$500\\
r=rate\to 6\%\to \frac{6}{100}\to &0.06\\
n=
\begin{array}{llll}
\textit{times it compounds per year}\\
\textit{semi-annually, thus twice}
\end{array}\to &2\\
t=years\to &2
\end{cases}
\\\\\\
A=500\left(1+\frac{0.06}{2}\right)^{2\cdot 2}\implies A=500(1.03)^4\implies A=562.754405$

now, "A" is the accumulated amount, including the earned interest, how much interest was it earned? well, is just A - P.

To make concrete it take 8 parts crushed gravel, 7 parts water and 5 parts cement mix. A worker needs to make 220 kg of concrete

Romashka-Z-Leto [24]

A complete load of concrete = 8 parts gravel + 7 parts water + 5 parts cement.

Total number of parts in every load = 8 + 7 + 5 = 20 parts

If total load = 220 kg, then 20 parts = 220 kg

Divide each side by 20 : 1 part = 11 kg

gravel = 8 parts = 8 x 11 kg = 88 kg
water = 7 parts = 7 x 11 kg = 77 kg
cement = 5 parts = 5 x 11 kg = 55 kg

Check: 88 + 77 + 55 = 220 yay !
