Answer:
Image result for Which expression could be used to find the circumference of the circle below?
Use the formula C = πd to find the circumference if you know the diameter. In this equation, "C" represents the circumference of the circle, and "d" represents its diameter. That is to say, you can find the circumference of a circle just by multiplying the diameter by pi.
Step-by-step explanation:
Answer:
See the table and the digure attached
Step-by-step explanation:
For this case we can create the following table to express the information:
Category Frequency Rel. Frequency
_______________________________
A 60 0.5 (50%)
B 24 0.2 (20%)
C 36 0.3 (30%)
_______________________________
Total 120 1.0 (100%)
The values for the relative frequencies are calculated like this:
And as we can see on the figure attached we have the distributions required
Using translation concepts, the note E would be louder with a higher amplitude of y, hence constant a has to be multiplied by a positive constant greater than 1.
<h3>What is a translation?</h3>
A translation is represented by a change in the function graph, according to operations such as multiplication or sum/subtraction either in it’s definition or in it’s domain. Examples are shift left/right or bottom/up, vertical or horizontal stretching or compression, and reflections over the x-axis or the y-axis.
In this problem, the function is given by:
y = asin(1320πx)
The intensity of a sound is given by it's amplitude a, hence, to make the sound stronger, we need to vertically stretch the graph of y, which is done when constant a is multiplied by a positive constant greater than 1.

20m per second, because the difference between -50 and 250 is 300, and just divide 300 by 15, because distance/speed.
