Suppose you stand in a hole and use a sling to launch a stone straight up. The stone starts with a velocity of 53 feet per second. It leaves
the sling 29 feet below ground level.
Write height (y feet) as a function of time (x seconds)
x f(x)
x x
Х
0 (x) x 2

Read the following question, then decide which strategy you will use.
Plug in x to find y
Plug in y to find x
Vertex, x coordinate: use

2a
and then 'plug in
What is the maximum height that the stone will reach? (nearest
hundredth)
label optional

your answer is the last one

step-by-step explanation:

divide the length of a'c' by the length of ac to get a scale factor of two

& then reflect vertically (over the y-axis)

so your answer is dilation by a scale factor of 2 followed by reflection over the y-axis

the required function is .

step-by-step explanation:

from the given table it is noticed that the graph passing through (-3,7), (0,4), (3,1) and (8,-4).

it is a linear function because the value of y is decrease by one as the value of x increase by 1.

the slope of the function is

the slope of the function is -1 and the y-intercept is 4.

the slope intercept form is

where, m is slope and b is y-intercept.

therefore the required function is . the graph of this function is shown below.

54 km / hours

step-by-step explanation:

we need to convert seconds to hours

60 seconds = 1 minutes

60 minutes = 1hour

15 m         60 second   60 minutes

  * *         = 54000 meters/ hour

second     1 minute             1 hour

now we need to convert meters to km

1000 m = 1 km

54000 m       1 km

*   = 54 km / hours

hour               1000m

answer: 0,6

step-by-step explanation:

this would make it the y intercept.
