Solution:

Given:

\begin{gathered} P=\text{ \$25,000} \\ r=\text{ 6\%}=\frac{6}{100}=0.06 \\ n=2(compounded\text{ semiannually)} \\ t=2\text{years} \end{gathered}

To get the compound amount, we use the amount formula;

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

Substituting the values given into the formula,

\begin{gathered} A=25000(1+\frac{0.06}{2})^{2\times2} \\ A=25000(1+0.03)^4 \\ A=25000(1.03)^4 \\ A=25000\times1.03^4 \\ A=28137.72 \\  \\ \text{Hence,} \\ A=\text{ \$28137.72} \end{gathered}

Therefore, the compound amount, if she invests for 2 years, is $28137.72

The sum of two numbers is 30 and their difference is 6
Studentka2010 [4]

I'm going to assume that you are trying to find the two numbers. Based on the information in the problem, we can create the following equations (where a and b are the two numbers):

a + b = 30

a - b = 6


We have a systems of equations. In this case, it would be easier to use elimination by adding vertically. This produces the result:

2a = 36

a = 18


To find b, substitute the value for a into one of the earlier equations:

18 + b = 30

b = 12


The two numbers are 12 and 18.

How do I solve these equations
Sever21 [200]
You need to know the properties of each function.
Tan is opposite (y) over adjacent (x).  Sin>0 means that sin is positive, therefore, it is located on either quadrant 1 or 2. Tan=4/3  so it is located in quadrant 1.
The side of the triangle must be Adjacent=3  opposite=4 and hypotenuse=5
Now, you are asked to find the half angle of Cos which is 
\sqrt{\frac{1+cos}{2} }
By following the formula, cos=3/5 then:
\sqrt{ \frac{1- \frac{3}{5} }{2} }    Multiply everything (inside the square          \sqrt{ \frac{5+3}{10} }                  root) by 5
\frac{2 \sqrt{2} }{ \sqrt{10} }
\frac{2 \sqrt{20} }{10}                Then just simplify
\frac{ \sqrt{20} }{5}      The answer is Square root of 20 over 5
