PLEASE HELP Path of A Ball
The path of a ball in flight is given by h(x) = -0.23(x - 3.4) + 4.2 where x is the
horizontal distance in meters and h(x) is the height in meters,
a.
b.
Find h(2) and give a real-world meaning for this value,
find the x-values for h(x) = 2, and describe the real-world meaning of
these values.
How high was the ball when it was released?
How far will the ball go before it hits the ground?
C.
d.

What is the solution of the systems of equations? y=2/3x+3 x=-2

How to do this , and can some one explain

An optical inspection system is used to distinguish among different part types. the probability of a correct classification of any part is 0.92. suppose that three parts are inspected and that the classifications are independent. let the random variable x denote the number of parts that are correctly classified. determine the probability mass function of x. round your answers to four decimal places (e. g. 98.7654). x f(x) 0 1 2 3
