2/5 - 1/4 = 8/20 - 5/20 = 3/20
(3/20)t = 24
t = 160
If you would like to simplify <span>7 - 3[(n^3 + 8n) / (-n) + 9n^2], you can do this using the following steps:
</span>7 - 3[(n^3 + 8n) / (-n) + 9n^2] = 7 - 3[(-n^2 - 8) + 9n^2] = 7 - 3[-n^2 - 8 + 9n^2] = 7 - 3[ - 8 + 8n^2] = 7 - 3[8<span>n^2 - 8] = 7 - 24n^2 + 24 = - 24n^2 + 31
</span>
The correct result would be <span>- 24n^2 + 31.</span>
Answer: 
Step-by-step explanation:
You need to analize all the information given in the exercise.
You know that the actual height of the T-rex on the projector lens is the following:

The height of the projected T-rex is:

Make the conversion from meters to centimeters:

Therefore, the scale factor will be:

Finally, you must substitute values into the equation and then you must evaluate in order to find the scale factor of the projection. You get that this is:

We know that, Amount in Compound interest is given by :

Given : Principal = $2000
Given : Annual yield is 5% and the interest is compounded quarterly
It means : Interest is compounded 4 times in a year


Substituting all the values in the formula, we get :
