If h is m above the ocean and your trying to find when the rocket reaches that ocean… as the function gives the height above the ocean at a given time, when the height equals 0 the rocket will have reached the ocean so solve for t when h=0. working out in the photo. i got t=48.88seconds
We know, Volume of a Cylinder = πr²h
Here, r = 2/2 = 1 ft
h = 3 ft
Substitute their values,
v = 3.14 * (1)² * 3
v = 9.42 ft³
In short, Your Answer would be: 9.42 Ft³
Hope this helps!
An equation for the sentence would be g + 7 = 12, where g is the unknown number of gallons.
A reflection across the x-axis has the rule:
(x,y)→(x,-y).
Then:
- A(-1,-1)→A'(-1,1),
- B(0,1)→B'(0,-1),
- C(4,2)→C'(4,-2),
- D(6,0)→D'(6,0),
- E(3,-3)→E'(3,3).
Answer: the vertices of the image are A'(-1,1), B'(0,-1), C'(4,-2), D'(6,0) and E'(3,3).
