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:
Answer:
1428 cubic inches
Step-by-step explanation:
The volume of a rectangular prism is 
, where V represent volume, l is the length, w is the width, and h is the height.
You are given that the length is 12 inches, the width is 7 inches, and the height is 17 inches.
Solve.
V = 12 * 7 * 17
V= 1428 in³
The simultaneous equations is missing +8
I don't have my glasss on and there are too many 1's which are messing with my eyes but all i have to say is PEMDAS
bonus question - i used to like school but at this point i just want to graduate
It is C, because the x values between the first dot and the second is 4. So you multiply the slope 4 times on the y value. The y value changes from -2 to -5, so -2 + 4*-3/4 should be equal to -5
