The answer is 2.5
Step-by-step explanation:
Formula = (N + 1 / 2th) term
So,
Total numbers (N) = 4
Now,
(N + 1 / 2th) term
= (4 + 1 / 2th) term
= (5 / 2th) term
= (2.5th) term

The height of the project becomes zero when it hits the ground which is also the total time at which the projectile stays in the air. Equating the function to zero:
-10(x)(x - 4) = 0
The roots of this quadratic equation are:
x = 0, and x=4
Therefore, the projectile stays in the air for
4 seconds
Answer:
Two integers that lie the same distance from the origin in opposite directions are called opposites. For example, "negative 5" is the opposite of "positive 5." Every number on the number line also has an absolute value, which simply means how far that number is from zero.
