The number of seconds it takes for the waste to hit the ground for the given function is: 5 seconds.
<h3>How to Evaluate a Function?</h3>
We are given the function of height to time as, h(t) = -16t² + initial height, and we have the following:
- h(t) = 0 (height of the ground is 0)
- t = seconds the waste takes to height the ground
- Initial height = 400 feet
Plug in the values into the equation of the function
0 = -16t² + 400
Solve for t
0 - 400 = -16t²
-400 = -16t²
-400/-16 = t²
400/16 = t²
√(400/16) = t
20/4 = t
5 = t
t = 5
The number of seconds it takes is: 5 seconds.

Given:
Vertices of a square are A(-4,6), B(5,6) C(4,-2), and D(-5,-2).
To find:
The intersection of the diagonals of square ABCD.
Solution:
We know that diagonals of a square always bisect each other. It means intersection of the diagonals of square is the midpoint of diagonals.
In the square ABCD, AC and BD are two diagonals. So, intersection of the diagonals is the midpoint of both AC and BD.
We can find midpoint of either AC or BD because both will result the same.
Midpoint of A(-4,6) and C(4,-2) is
Therefore, the intersection of the diagonals of square ABCD is (0,2).
Answer:
Length of IK is 8 feet, EK is 11 feet and BE is 25 feet.
Step-by-step explanation:
It is given that radius for circle B is 6 feet, circle K is 14 feet and circle D is 3 feet. In order to find the length, you have to either substract or add up :
IK = BK(radius of K) - BI(radius of B)
= 14 - 6
= 8 feet
EK = DK(radius of K) - DE(radius of D)
= 14 - 3
= 11 feet
BE = BK + EK(answer above)
= 14 + 11
= 25 feet
