Answer:so I’m trying to do the challenge and answer random questions so don’t mind me
Step-by-step explanation:
Answer:
- <u>The zero is x = 5, and it represents that the diver will enter the pool's surface 5 feet in front of the diving board.</u>
Explanation:
The function is f(x) = - x² - 5x + 50.
Where:
- f(x) is the vertical distance of a diver from a pool's surface, and
- x is the horizontal distance of a diver from the diving board.
A zero of f(x) represents a point where the diver is at the surface of the pool. There might be two possible zeros.
Solve the equation to determine the zeros:
- Multiply both sides by - 1: x² + 5x - 50
- Factor: (x + 10) (x - 5) = 0
- Use zero product property: x + 10 = 0 or x - 5 = 0
- From x + 10 = 0 you get x = - 10
- From x - 5 = 0 you get x = 5.
- The negative zero is not valid as it would be a point behind the diving board, so the meaningful zero is when x = 5, meaning that the diver will touch the surface of the pool at 5 feet in front of the diving board.
Step-by-step explanation:
Given sequence is: - 3, 5, 13...
Here first term a = - 3
common difference d= 5-(-3)=13-5=8
Hence, it is in A. P.
Nth term of an AP is given as:

Which is the required formula for the given sequence.
The numerical value if the expression is 0
The expression to be solved is

<h3>How to solve the given expression</h3>
sin ( pi/3 ) = 
2sin ( pi/3 ) = 2 *
= 


since 100 is even

These are alternate interior angles. They are both on the inside, but on opposite (alternate) sides. Alternate interior angles are always equal to each other.
Hope this helps!!
