The answer is 645.88 y because you have to multiply them together in order to get your answer.
Answer:
Option A is correct
Step-by-step explanation:
The equation that the first option is talking about would be 5-X=-10
Answer:
5.59 times per second.
Step-by-step explanation:
Direct variation is in the form:

Where <em>k</em> is the constant of variation.
Inverse variation is in the form:

In the given problem, the frequency of a vibrating guitar string varies inversely as its length. In other words, using <em>f</em> for frequency and <em>l</em> for length:

We can solve for the constant of variation. We know that the frequency <em>f</em> is 4.3 when the length is 0.65 meters long. Thus:

Solve for <em>k: </em>
<em />
<em />
<em />
So, our equation becomes:

Then when the length is 0.5 meters, the frequency will be:

A 252
To find area of a trapezium it is 1/2 the sum of the parallel sides time the height between them in this case it is 1/2(6+12)(8)
The answer would be 2.564
