A projectile is shot into the air. The altitude of the projectile after seconds is modeled by the function graphed. Time is measured in seconds and altitude ℎ() is measured in feet. The table models the flight of the projectile.

Which of these statements is true?
A.
ℎ(4) < ℎ(20)
B.
The flight is symmetric about the line = 10.
C.
The projectile will hit the ground at some value of less than 24.
D.
f 0 < < 12, then ℎ(12 − ) = ℎ(12 + ).

What are correct trigonometric ratios that could be used to determine the length of ln

Determine whether the following statements are true and give an explanation or counterexample. bold a. when using the shell method, the axis of the cylindrical shells is parallel to the axis of revolution. bold b. if a region is revolved about the y-axis, then the shell method must be used. bold c. if a region is revolved about the x-axis, then in principle it is possible to use the disk/washer method and integrate with respect to x or the shell method and integrate with respect to y.
