Answer from: dvandebrake2002

The gravity's constant value is 9.8 m/sec^2 .

Explanation:

The given function shows the distance from the ground (in meters) at time t (in sec).

d(t)=-4.9t^2+50

First derivative of displacement is velocity and the second derivative of displacement is acceleration.

Differentiate the given equation with respect to t.

v(t)=d'(t)=-9.8t+0

Differentiate the above equation with respect to t.

a(t)=v'(t)=d''(t)=-9.8

It is given that gravity is the only acceleration affecting the object and the negative sign shows the downward direction of the object.

Therefore, the gravity's constant value is 9.8 m/sec^2 .

Answer from: Quest

answer: the proof is mentioned below.

step-by-step explanation:

since, given: lines bc = ef

prove: lines ac > ef

statements reason

1. bc=ef 1. given

2. ac= ab+bc 2. because b is the point between the

line segment ac

3. ac > bc 3. because if a line segment is equal to

the sum of two line segments then it is

always greater then each of these

individual line segments

4. ac > ef 4. by equality property.
