Answer:
40%
Step-by-step explanation:
When all 480 sixth-grade students at Golden State Middle School were polled, results showed that 192 students were dissatisfied with the music played at the school dance. What percentage of sixth-grade students does this represent?
This is calculated as
(Number of dissatisfied students/Total number of students) × 100
= 192/480 × 100
= 40%
The percentage of sixth-grade students that this represents is 40%
Answer:

$.65.
Answer:
(a) The maximum height of the ball is 16 feet at 1 seconds.
(b) The ball hits the ground at 2 seconds.
PART (A) :
Given function: h(t) = -16t² + 32t
Comparing to quadratic function: ax² + bx + c
In this function: a = -16, b = 32, c = 0
<u>To find the maximum height</u>, use the vertex formula:
<u>Insert values</u>
Then find h(t) = -16(1)² + 32(1) = 16 feet
Conclusion: The maximum height of the ball is 16 feet at 1 seconds.
PART (B) :
When the ball hits the ground, the height [h(t)] will be 0 ft
-16t² + 32t = 0
-16t(t - 2) = 0
-16t = 0, t - 2 = 0
t = 0, t = 2
The ball hits the ground at 2 seconds. Note: the other 0 seconds is for when the ball was launched at the beginning.
