Answer:
<em>Mrs. Adams will earn $3,120 of interest at the end of year 8.</em>
Step-by-step explanation:
<u>Simple Interest</u>
In simple interest, the money earns interest at a fixed rate, assuming no new money is coming in or out of the account.
We can calculate the interests earned by an investment of value A in a period of time t, at an interest rate r with the formula:

Mrs. Adams deposited an amount of A=$12,000 into an account that earns an annual simple interest rate of r=3.25%. We must find the interest earned in t=8 years. The interest rate is converted to decimal as:

The interest is then calculated:

Mrs. Adams will earn $3,120 of interest at the end of year 8.
A because 2(1)/(5) is less than 2(3)/(5).
Answer:
Use this to solve 3
Step-by-step explanation:
Area = 1/2 b.c sin A
=1/2(13.1)(8.7)sin29. 17
Answer:
The graph is shown below.
Step-by-step explanation:
Given:
The inequality of a line to graph is given as:

In order to graph it, we first make the 'inequality' sign to 'equal to' sign. This gives,

Now, we plot this line on a graph. The given line is of the form:
Where, 'm' is the slope and 'b' is the y-intercept.
So, for the line
, 
The y-intercept is at (0, -3).
In order to draw the line correctly we find another point. Let the 'y' value be 0.
Now, 
So, the point is (3, 0).
Now, we mark these points and draw a line passing through these two points.
Now, consider the line inequality
. The 'y' value is less than
. So, the solution region will be region below the line and excluding all the points on the line. So, we draw a broken line and shade the region below it.
The graph is shown below.
So imma be using the Pythagorean Theorem, which is

. The a and h variable represent the legs of the right triangle while c variable stands for the hypotenuse. And since we have one of the legs and the hypotenuse, we are solving for the other leg.
So first we are gonna plug in 60 and 63 in their appropriate spots:

Solve the exponents to get

Subtract 3600 on each side to get

To cancel out the squared power, you have to square root each side of the equation, and your final answer should be
