Answer:
−0.0005 m/sec.
Step-by-step explanation:
Let us denote the volume of the can as V
let us denote the radius of the circular disc in lake as r
Let us denote the thickness of the circular disc as h
But we know the volume of the can as πr^2h then we can calculate How fast it is decreasing when the radius is 2 m

Answer:
3.2
Step-by-step explanation:
Answer: Chad, Stephen, Jose and Mrquis
Step-by-step explanation:
We can change them to Percentage to make their ordering easier.
Mrquis ran 1/2 mile = 1/2 × 100 = 50%
Chad ran 7/8 mile = 7/8 × 100 = 87.5%
Jose ran 3/5 mile = 3/5 × 100 = 60%
Stephen ran 3/4 mile = 3/4 × 100 = 75%
Therefore, the ordering from the greatest to the least will be:
Chad, Stephen, Jose and Mrquis
3. you cannot simplify √30
Answer:
2 real solutions
Step-by-step explanation:
y = -x^2 + 3x + 5
First find the the discriminant:
using b² - 4(a)(b)
(3)²- 4(-1)(5)
=9+20
=29
since the discriminant is more than 0, there are 2 real solutions
