Calculus! First one I've seen here! Take the derivative of the volume of a cube. Volume is V = s^3, dV = 3s^2 ds when s = 10 and ds = 3. I think you used x. Anyway, in the derivative fill in the s with a 10 and the ds (rate of change) is 3. So dV = 3(10)^2 * 3
dV = 600 cm per second
Answer:
The relationship is Y=2.5X
Step-by-step explanation:
From the sentence
X= 2 and Y= 5
Hence (X/Y) = 2/5
Hence Y= 5X/2 = 2.5X
Answer:
use the zero as an common multipal
Step-by-step explanation:
W=45 when you add over the -4 to get the w variable by itself
Find the length of MN by setting up a ratio:
Let MN = X
X/18 = 5/6
Cross Multiply:
6x = 90
Divide both sides by 6:
x = 15
Now you know MN add it to LM for the total length of LN:
15 + 5 = 20
