Answer:
Step-by-step explanation:
-5 + 7p + 14 + 11p = 18p + 9
18p + 9 = 18p + 9
0 = 0
Pedro is correct
Answer:
V ≈ 263.9 units³
Step-by-step explanation:
The volume (V) of a cone is calculated as
V =
πr²h ( r is the radius and h the height )
Here r = 6 and h = 7 , then
V =
π × 6² × 7
=
π × 36 × 7
=
π × 252
= 84 π
≈ 263.9 units³ ( to 1 dec. place )
For this case, we can model the problem as a triangle with a right angle.
Where,
x, y: lengths of the sides of the triangle
d: hypotenuse of the triangle
We then have the following relationship:

Clearing d we have:
Answer:
A functions that would best model the situation above is:
D square root
Answer:
The rate of change is -0.75
Step-by-step explanation:
For each unit of <em>t</em> the volume of water is decreasing by 0.75.
At <em>t</em>=13.333 the volume of water is 0. at <em>t</em>=0 the volume of water is 10
