Answer:
I hope you feel better
Step-by-step explanation: don’t be sad
First, you have to find the moment of inertia along the x and y axes. Constant density is denoted as k.
Then, the radii of gyration for
x = √[I_x/m]
y = [I_y/m]
where m = k(15-4)² = 121k. Then,
x = y = [4880.33k/121k] = 40.33
I hope I was able to help you. Have a good day.
Answer:
150 boys were enrolled in 2012
Step-by-step explanation:
Let the number of boys enrolled in 2012 be x
Let the number of girls enrolled in 2012 be x + 200
Ratio of boys to girls in 2012 enrollment = 3/7
Now;
3/7 = x/x + 200
7x = 3(x + 200)
7x = 3x + 600
7x - 3x = 600
4x = 600
x = 600/4
x = 150 boys
Hence, 150 boys were enrolled in 2012
If y represents the total number of cans already crushed at a given time,
<span>and x represents the number of minutes, </span>
<span>then we can observe that this is a point-slope equation for the point (5,65). </span>
<span>The point-slope format is </span>
<span>y - b = m (x - a) </span>
<span>where m is the slope of the line </span>
<span>and (a,b) are coordinates of a point on the line. </span>
<span>Since we're given b=65, we find the x-coordinate that corresponds to 65 on the table, </span>
<span>and therefore we know a=5. </span>
<span>We also need to fill in the blank for the slope. It turns out the slope is constant for the whole table, so we can use any two points to calculate it. Using the endpoints (3,49) and (9,97), we get </span>
<span>m = (difference in y-coordinates) / (difference in x-coordinates) </span>
<span>= (97 - 49) / (9 - 3) = 48/6 = 8 </span>
<span>So now we know that a=5, b=65, m=8 and the point-slope equation </span>
<span>y - b = m (x - a) </span>
<span>turns out to be </span>
<span>y - 65 = 8 (x - 5)</span>
