A steel worker dropped his wrench off the top of a new high rise building. How far will the wrench fall in 3 seconds?

rosijanka [135]

Using S = ut + 1/2gt², from rest, u = 0

S = 1/2gt², g ≈ 9.8 m/s²

S = 1/2 *9.8*3²

S = 0.5 *9.8*3*3

S ≈ 44.1 m

You can either find the roots of the quadratic formula using the quadratic formula two find the halfway point or you can use the formula t=-b/2a. Both of the two methods gives you the axis of symmetry (the t value for the vertex).
I will use the second method since I don't like using the quadratic formula.
t=-32/(2x-16)
t=1 second
After you find the t value for the axis of symmetry, you plug it into the formula of the graph to find the height.
h=-16+32+14
h=30 feet

Convert y-3=(1/3)(x+1) to slope intercept form

Mekhanik [1.2K]

Slope-intercept form is $y=mx+b$ , where m is the slope and b is the y-intercept.

Here, we first need to distribute the 1/3.

$y-3= \frac{1}{3} x+\frac{1}{3}$

Next, we add 3 to both sides of the equation.

$y= \frac{1}{3} x+\frac{10}{3}$

What is the equation of a line that passes through the points (3, 6) and (8, 4)?

Answer:

y = -2/5x +36/5 . . . . . slope-intercept form

2x +5y = 36 . . . . . . . . standard form

Step-by-step explanation:

You can use the 2-point form of the equation of a line to find it.

y = (y2 -y1)/(x2 -x1)(x -x1) +y1

y = (4 -6)/(8 -3)(x -3) +6

y = -2/5(x -3) +6

y = -2/5x +36/5 . . . . slope-intercept form

2x +5y = 36 . . . . . . . standard form
