So there's six possible answers to each question. So six times two, is 12. And by looking at the choices, I think the answer is D.
The equation is in the format
where a is the initial value (when t=0), b is the rate of change between terms, and t is the amount of time.
Our initial value is 100. We find the rate of change by first finding the percent of change:
amount of change/original amount
= 20/100 = 0.2
This is a percent decrease, so we will subtract it from 1:
1-0.2 = 0.8
This goes in for b.
The diagonal of a right rectangular prism is the line that connect opposite vertices. In other word is the distance from corner to corner in the right rectangular prism. Since the diagonal of a right rectangular prism is the hypotenuse of a right triangle, we are going to use a variation of the Pythagorean theorem to find it. In essence, we just need to add another dimension to the Pythagorean theorem; in this case the height of our prism:
We can conclude that the formula to calculate the length of the diagonal of a right rectangular prism is:
where
is the length of the diagonal.
is the length of the rectangular base of the prism.
is the width of the rectangular base of the prism.
is the height of the prism.
Hi,
Here is my work. I have factored an expression.
Hope this helps.
