Jessica is eating a bag of sour skittles . Her friend ask her to share, and Jessica throws over an extra bag. Her friend does no

t catch the bag, and it hits the ground. The distance from the ground (height) for the bag of candies is modeled by the function h(t)= -16t²+32t+4 where h(t) is the height (distance from the ground in feet ) of the candies and t is the number of seconds the candies are in the air. Describe in a paragraph what the graph of this scenario would look like.

Answer:

A parabola opens downward with vertex at (1,20)

Step-by-step explanation:

The function that models the height of bag of candies is

h(t) =  - 16 {t}^{2}  + 32t + 4

The graph of this function is a parabola that opens downward.

To find the maximum height of the candy bag, we complete the squares to obtain the vertex form of the function.

Factor -16 to get;

h(t) =  - 16( {t}^{2}  - 2t) + 4

Add and subtract the square of half the coefficient of t.

h(t) =  - 16( {t}^{2}  - 2t + 1)  + 16+ 4

Factor the perfect square trinomial:

h(t) =  - 16( {t - 1)}^{2}  + 20

The vertex is (1,20)

This means the maximum height after 1 second is 20 feet.

The world's smallest plane has a length of 12 feet and the world's longest plane has a length of 302 feet. Write an absolute val
iren [92.7K]

An absolute value equation which could represent the length of a plane is : 12 feets ≥ x ≤ 302 feets

Smallest length of a plane = 12 feets

Longest length of a plane = 302 feets

This means that the minimum length of a plane cannot be below 12 feets and the maximum length of a plane cannot be above 302 feets

Using x as the length of a plane :

To represent as an absolute value ; we use inequality :

Minimum length ≥ x ≤ maximum length

12 feets ≥ x ≤ 302 feets .
