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

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;

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

Factor the perfect square trinomial:

The vertex is (1,20)
This means the maximum height after 1 second is 20 feet.
Answer: 44.9 ft
Explanation: 5.6/8.1=0,6913 65•0,6913=44,94 ft
Answer:
10
Step-by-step explanation:
A rational number is 9.
When you multiply 0.9x10 you get the sum of 9.
9 is a rational number because it is a perfect square and an integer.
I hope this helps you understand :)
Answer:
w= -27
Step-by-step explanation:
w/3 = -9
w = 3 * -9 = -27
