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

What is the rate of change of the equation y=0.86x+3.302

Alchen [17]

The rate of change of the given equation is: 0.86

Step-by-step explanation:

Rate of change or slope is the steepness of a linear function or line.

When an equation is given in the form of slope-intercept form, the co-efficient of x is the slope or rate of change of the equation.

Given equation is:

$y=0.86x+3.302$

We can see that the co-efficient of x is 0.86

Hence,

The rate of change of the given equation is: 0.86
