The table below shows the height, h, in meters, of an object that is thrown off the top of a building as a function of t, the time in seconds after it is thrown. (Table attached) Part 1: Express the height of the object as a function of the number of seconds that have passed since the object was thrown. (Round all numbers to 1 decimal place.)

Part 2: Using your quadratic regression, how high will the object be 2.8 seconds after it is thrown? (Round to 3 decimal places.)

Part 3: Using your quadratic regression, how long will it take the object to reach 25 meters? (Round to the 3 decimal places.)

options a,b,c are the right answer.

step-by-step explanation:

a linear parent function is always represented as y = x

if we write this function in the form of y=mx+c

⇒

or  

now if we plot a graph we will find these characteristics:

1) y intercept of the graph is zero so its a straight line passing through origin.

2) as we can see in both the forms of function written, values of x and y may be either positive or negative for the positive slope means points on the graph are either in first quadrant or in third one.

3) it's slope is one.

all the angles opposite to the angle 150 would be 150 and all the angles that are next to 150 are 30 because they equal 180 it you add it up.
