No, since 0 doesn't belong to the domain.
Answer:
−8xf+16xg
Step-by-step explanation:
im not sure if thats correct but you should be using vector arithmetic to simplify the answer.
Answer:
= 5
Step-by-step explanation:
Substitute the given values into the formula
16 =
× 4(3 +
)
16 = 2(3 +
) ( divide both sides by 2 )
8 = 3 +
( subtract 3 from both sides )
5 =
9514 1404 393
Answer:
68.6 m/s
Step-by-step explanation:
The speed at a given time is the derivative of the height at that time.
dh/dt = -9.8t
At t=7, the speed is ...
-9.8(7) = -68.6 . . . . . meters per second (downward)
The speed is 68.6 meters per second.

<em>Additional comment</em>
Height is considered to be positive in the up direction, so velocity and acceleration are also positive in the up direction. The derivative of height will be the velocity. Its negative sign in this case indicates the object is moving in the downward direction. The speed is the magnitude (absolute value) of the velocity.
