A ball is thrown into the air by a baby alien on a planet in the system of Alpha Centauri with a velocity of 50 ft/s. Its height in feet after t seconds is given by y=50t−28t^2 .

A. Find the average velocity for the time period beginning when t=2 and lasting

.01 s:

.005 s:

.002 s:

.001 s:

NOTE: For the above answers, you may have to enter 6 or 7 significant digits if you are using a calculator.

Estimate the instanteneous velocity when t=2.

step-by-step explanation:

let f (x ) is a function and c be a positive real number,   the graph of the function g (x ) = f (cx ) is represented as follows.

when, c > 1,   the function compresses it in the x - direction.

when, 0 < c < 1, the function stretches it.

the function is g ( x ) = (9x )2.

the heighest power of x in g ( x ) = (9x )2 is 2, so the parent function is square function.

the equation of parent function is f ( x ) = x 2 .

the function is g ( x ) = (9x )2 and the parent function is f ( x ) = x 2 .

so, the functions f and g have the following relationship.

g ( x ) = f ( 9x ).

compare the function g ( x ) = f ( 9x ) with g (x ) = f (cx ).

c = 9 ( > 1 ).

so, the function g (x ) = (9x )2 compresses it in the x - direction.

do it yourself this is easy

step-by-step explanation:

i believe it is the square root of 122 because when you turn it on it's side, to where the 5 inches is on the bottom, it looks like it is the same length.
