Answer:

12 $\sqrt{6}$ + 8 $\sqrt{15}$ + 12 + 4 $\sqrt{10}$

Step-by-step explanation:

Using the rule of radicals

$\sqrt{a}$ × $\sqrt{b}$ ⇔ $\sqrt{ab}$

Given

(4 $\sqrt{3}$ + 2 $\sqrt{2}$ )(3 $\sqrt{2}$ + 2 $\sqrt{5}$ )

Each term in the second factor is multiplied by each term in the first factor, that is

4 $\sqrt{3}$ (3 $\sqrt{2}$ + 2 $\sqrt{5}$ ) + 2 $\sqrt{2}$ (3 $\sqrt{2}$ + 2 $\sqrt{5}$ ) ← distribute both parenthesis

= 12 $\sqrt{6}$ + 8 $\sqrt{15}$ + 12 + 4 $\sqrt{10}$

Answer:

1.176 grams

Step-by-step explanation:

Given:

Recommended dose

21 mg per day for 6 weeks

Now,

1 week = 7 days

Thus,

number of days in 6 weeks = 6 × 7 = 42 days

Therefore, the total dose = dose per days × number of days

= 21 × 42 = 882 mg

further,

14 mg per day for 2 weeks

Now,

1 week = 7 days

Thus,

number of days in 2 weeks = 2 × 7 = 14 days

Therefore, the total dose = dose per days × number of days

= 14 × 14 = 196 mg

further,

7 mg per day for 2 weeks

Now,

1 week = 7 days

Thus,

number of days in 6 weeks = 2 × 7 = 14 days

Therefore, the total dose = dose per days × number of days

= 7 × 14 = 98 mg

Hence, the total dose = 882 + 196 + 98 = 1176 mg

also,

1 g = 1000 mg

thus,

1176 mg = 1.176 grams

total quantity received during this course is 1.176 grams

How much money should be invested at 5% interest, compounded quarterly, so that 7 years later the investment will be worth $5000

vampirchik [111]

$\bf \qquad \textit{Compound Interest Earned Amount}
\\\\
A=P\left(1+\frac{r}{n}\right)^{nt}
\quad 
\begin{cases}
A=\textit{accumulated amount}\to &\$5000\\
P=\textit{original amount deposited}\\
r=rate\to 5\%\to \frac{5}{100}\to &0.05\\
n=
\begin{array}{llll}
\textit{times it compounds per year}\\
\textit{quarterly, four times}
\end{array}\to &4\\
t=years\to &7
\end{cases}
\\\\\\
5000=P\left(1+\frac{0.05}{4}\right)^{4\cdot 7}\implies 5000=P(1.0125)^{28}\\\\\\ \cfrac{5000}{(1.0125)^{28}}=P$
