Answer:
a) The maximum height that the ball reaches is 73.1 meter
b ) The time elapsed when the ball reaches its maximum height of flight = 2.2 seconds
Step-by-step explanation:
The complete question is
During a high school baseball tournament, Lando hits a pitch and the baseball stays in the air for 4.42 seconds. The function h(t) = -5t2 + 22t + 0.5 describes the height over time, where h is its height, in meters, and t is the time, in seconds, from the instant the ball is hit. a. What is the maximum height the ball reaches? b. What will be the time elapsed when the ball reaches its maximum height of flight?
Solution:
For maximum height
seconds
a) Maximum height
b) Time elapsed when the ball reaches maximum height is 2.2 seconds
Base×Height = Area
So put (2x-6)(x+3) which equals
2x^2+6x-6x-18
Combine like terms=
2x^3-18
Simplify by diving each term by 2 since both terms have factors of 2.
Final Answer = x^2-9
Given:
Length of chords of one segment = 11 and 8
Length of chords of other segment = 2 and x
To find:
The value of x.
Solution:
<em>If two chords intersect each other inside a circle, the products of length their segments are equal.</em>
Divide by 2 on both sides.
Switch the sides.
The value of x is 44.
3.79 + .79 + .99 = 5.57
So the entire lunch costs $5.57
