Answer:
y = 49
Step-by-step explanation:
y ∝ x²
=> y = kx²
<u><em>Where k is the constant of proportionality</em></u>
k = 1 (We've found this out in the previous question)
Now,
y = ? when x = 7
<u><em>The above equation becomes:</em></u>
=> y = (1)(7)²
=> y = (1)(49)
=> y = 49
Answer:
13/30
Step-by-step:
First, you find the common denominator, which is 30. For the first fraction, multiply the bottom by five. Since you do that, you have to multiple the top by 5 as well, giving you 25/30. For the second problem, you multiple the top and bottom by six giving you 12/30. 25 minus 12 is 13 so you get 13/30.
<span>They are both functions of the cube of the radius or even the cube of the diameter for that matter, since one is a linear function of the other.
V=(4/3) pi r^3
If you do volumes of both, the (4/3) and the pi cancel
Do ratios of r^3 Thats just an example</span>
