Find the missing side. It’s trigonometry, and I’ve tried this 5 times.
GenaCL600 [577]
That triangle's upside down but the usual rules hold.

We know the side opposite the 39 degree angle is 10 m and we're asked for the adjacent side.  The unlabeled side is the hypotenuse.

That's tangent:

\tan 39^\circ = \dfrac{10}{x}

x = \dfrac{10}{\tan 39^\circ} \approx 12.35 \textrm{ m}

You deposit $2000 in an account earning 3% interest compounded monthly. How much will you have in the account in 5 years
Nadusha1986 [10]

Answer:

$2,323.23

Step-by-step explanation:

Lets use the compound interest formula provided to solve this:

A=P(1+\frac{r}{n} )^{nt}

<em>P = initial balance</em>

<em>r = interest rate (decimal)</em>

<em>n = number of times compounded annually</em>

<em>t = time</em>

<em />

First, we will change 3% into its decimal form:

3% -> \frac{3}{100} -> 0.03

Now, plug the values into the equation:

A=2,000(1+\frac{0.03}{12})^{12(5)}

A=2,323.23

After 5 years, you will have $2,323.23

(13.) What is the first term if
Softa [21]

Answer:the first term is 6

Step-by-step explanation:

We would apply the formula for determining the sum of n terms of an arithmetic sequence. It is expressed as

Sn = n/2(a + l)

Where

n represents the number of terms in the arithmetic sequence.

l represents the last term in the arithmetic sequence.

a represents the first term in the arithmetic sequence.

From the information given,

l = 204

n = 12

Sn = 1260

We want to determine a. Therefore,

1260 = 12/2(a + 204)

1260 = 6(a + 204)

a + 204 = 1260/6 = 210

a = 210 - 204 = 6
