Remember that we can calculate the sinmple interest earned in an investment or saving using the formula:
Where:
P is the money invested/saved
R is the rate of interest
T is the time of the investment/deposit in years
Using this formula and the data given, we get:
Therefore, the interest earned is $285.60
In 16 years if her parents put in $1,000 and accrues 3.75% interest annually; in 16 years she will have $1,600 in the account.
To find this we need to multiply the amount deposited originally, by the annual percentage, by the amount of years in total.
We'll change the percentage into a decimal by moving the decimal two places to the right; which will change it to 0.0375.
Our equation will look like this:
1,000 x 0.0375 x 16
1,000 x 0.0375 = 37.50
37.50 x 16 = 600.
So, in 16 years at 3.75%, she will earn $600 in interest.
We'll add the interested of $600 to the original deposited amount of $1,000.
$1,000 + $600 = $1,600.
The answers are:
P ' = (-4,-7)
Q ' = (-8,-7)
R ' = (-3,3)
------------------------------------------------------------------------------------
All you do is swap the x and y coordinates of the given points P, Q and R
The general rule is (x,y) ---> (y,x)
So that's why something like P = (-7,-4) becomes P ' = (-4,-7) when we reflect over the line y = x. The other points are handled the same way.
3 * 12,348,335 = 37,045,005.
