Josh earns $2700 each summer and puts the money in a savings account with a 4.5% simple interest rate. If he deposits the same a

iragen [17]

Answer: Option 'B' is correct.

Step-by-step explanation:

Since we have given that

Amount Josh earn each summer = $2700

Rate of simple interest = 4.5%

According to question, he deposits the same amount each year.

First summer, he deposited = $2700

In Second summer, he deposited = $2700×2= $5400

In Third summer, he deposited = $2700 × 3=$8100

At the end of his third summer, his money becomes,

$\text{Simple Interest}=\frac{P\times R\times T}{100}\\\\\text{Simple Interest}=\frac{8100\times 4.5\times 1}{100}\\\\\text{Simple Interest}=\$364.5$

As we know the formula for "Amount" that it becomes at the end of his third summer:

$Amount=P+S.I\\\\Amount=\$8100+\$364.5\\\\Amount=\$8464.5$

Hence, Option 'B' is correct.

The angle θ lies in Quadrant II .

Andreyy89

let's keep in mind that, in the II Quadrant, cosine is negative and sine, is positive.

cosine is adjacent/hypotenuse, however the hypotenuse is simply a radius unit, and thus is never negative, so in the -(2/3) the negative must be the numerator, -2.

$\bf cos(\theta )=\cfrac{\stackrel{adjacent}{-2}}{\stackrel{hypotenuse}{3}}\impliedby \textit{let's find the \underline{opposite side}} \\\\\\ \textit{using the pythagorean theorem} \\\\ c^2=a^2+b^2\implies \sqrt{c^2-a^2}=b \qquad \begin{cases} c=hypotenuse\\ a=adjacent\\ b=opposite\\ \end{cases} \\\\\\ \pm\sqrt{3^2-(-2)^2}=b\implies \pm\sqrt{5}=b\implies \stackrel{\textit{II Quadrant}}{+\sqrt{5}=b}~\hfill tan(\theta )=\cfrac{\stackrel{opposite}{\sqrt{5}}}{\stackrel{adjacent}{-2}} \\\\\\ ~\hspace{34em}$

Please explain how you got the answer also, thank you

harina [27]

Answer:

See Explanation

Step-by-step explanation:

You are doing simple math within the square root. For instance where x=-2 you substitute -2 for x then add 2 which gives you 0 leaving you with -6.

for x=2 you end up with "square root 2+2" which gives you 4 and the square root of 4 is 2 so you add -6 to 2 giving you the answer of -4.
