The last one is the only one that makes sense according to the standard position function.  -16t^2 is the pull of gravity on an object in free fall, and the height is 120 feet above the ground.  Hopefully that's what you need since there's no graph we can refer to

<h2>Answer:</h2>

The explanation that best provides the real-world scenario is:

If an object is dropped from a height of 120 feet, the function                    

                          h(t)=-16t^2+120

gives the height of the object after t seconds.

<h3>Step-by-step explanation:</h3>

a)

If an object is dropped from a height of 120 feet, the function h(t)=-16t^2-120 gives the height of the object after t seconds.

This option is incorrect.

Since when t=0 we have:

           h(t)= -120

This is not possible as the object is above the ground and hence must have positive height initially.

b)

If an object is dropped from a height of -16 feet, the function h(t)=-16t^2+120 gives the height of the object after t seconds.

This option is incorrect.

Since a object when is dropped from some height then it must be a positive height.

Also, when t=0 we have: h(t)= 120 feet.

This means that the object is dropped from a height of 120 feet.

c)

If an object is dropped from a height of 120 feet, the function h(t)=-16t^2+120 gives the height of the object after t seconds.

In this when t=0 we have:

h(t)=120 that means the height of the object initially was 120 feet and then it decreases with the increase in time as the object will reach the ground with the time increase and hence height will decrease.

               Hence, this option is correct.

Kyle's height increased 17 % last year and 12% this year. What is the total percent increase ?
Advocard [28]

Answer:

31.04%

Step-by-step explanation:

So he increased 17%, then increased 12%.

When he increased by 17%, his height was 117%, relative to his former height.  12% of 117% is 14.04%

So he increase 17%, then increased 14.04% ( of his original height) so his total growth was 31.04%
