Answer:

Step-by-step explanation:

28) y = \frac{1}{2} x+1

You need to find the slope of the line between (0,1) and (2,2). You do that by using m = \frac{y2-y1}{x2-x1} ; The slope of the line is m = \frac{1}{2}.

29) y = -2x-5

30) y = -\frac{1}{2} x+2

31) y = \frac{8}{3} x-\frac{2}{3}

32) y = 2x-\frac{3}{4}

33) y = -\frac{3}{2} x+4.5

Murrr4er [49]
<h3><u>Question:</u></h3>

The formula h = 120t-16t^2 gives the height h in feet of an object t seconds after it is shot upward from Earth's surface with an initial velocity of 120 feet per second. What will the height of the object be after 6 seconds?

<h3><u>Answer:</u></h3>

The height of object after 6 seconds is 144 feet

<h3><u>Solution:</u></h3>

<em><u>The formula that gives the height of an object is:</u></em>

h = 120t - 16t^2

Where,

h is the height in feet and t is the time in seconds

To find: height of the object be after 6 seconds

To find the height of the object be after 6 seconds, substitute t = 6

h = 120 \times 6 -16(6)^2\\\\h = 720 - 16 \times 36\\\\h = 720 - 576\\\\h = 144

Thus height of object after 6 seconds is 144 feet
