Answer:
Rate of increase in height =
Step-by-step explanation:
we know that volume of a cone is given by
It is Given that diameter equals height thus we have
Differentiating both sides with respect to time we get
Applying values and solving for 
we get
If you would like to evaluate u + xy, you can do this using the following steps:
u = 18, x = 10, y = 8
u + xy = 18 + 10 * 8 = 18 + 80 = 98
The correct result would be C. 98.
T(x, y) = (x - 5, y - 6) since you are trying to translate back to the original point and therefor should do the reverse set of translations
Answer:
Step-by-step explanation:
This question is about the benefits of estimation.
1300/13 is easy and results in 100.
1287/13 can be approximated by 1300/13: 1287/13 ≈ 100.
Actually, 1287 = 1300 - 13 = 13(99); just subtract 1 from 100.
So: 1287/13 = 1300 - 13 = 1287. A nice bit of mental math!
The volume of cone formula is 1/3 times pi times radius^2 times height. So in this case the formula which numbers substituted in would be 1/3 times pi times 8^2 times 12. The final answer would be 804.2477 and if rounded it would be 804.2 m^2
