If the mine winch drum diameter is 6 m, calculate how far the cage will drop for each single rotation of the drum.use formular c

frozen [14]

The cage will drop 18.84m for each single rotation of the drum.

It is given that the diameter of the mine winch, d= 6 m.

We can calculate that how far the cage will drop for each single rotation of the drum by using the formula of the circumference.

Circumference, c = 2πr

where,

r = d/2 (radius of the mine winch)

r = 6/2

⇒ r = 3m

Circumference, c = 2πr

⇒ c = 2π×(3)

⇒ c = 6π

⇒ c = 18.84m

Hence, the cage will drop 18.84m for each single rotation of the drum.

Can someone explain how to do problems like <br> (-2+4) or (4+ -6)

KiRa [710]

Answer:

All you have to do is just add the numbers inside the parenthesis. (4+-2) is the same as 4-2 which is equal to 2. (4+-6) is the same as 4-6 which is equal to -2.

Graph the linear equation and answer each of the following questions. y=-2x-3

ollegr [7]

Answer:

Part 1) The y-intercept is the point (0,-3)

Part 2) The slope in fraction form is $m=-\frac{2}{1}$

Part 3) The graph in the attached figure

Step-by-step explanation:

we have

$y=-2x-3$

Part 1) What is the y-intercept?

Remember that

The y-intercept is the value of y when the value of x is equal to zero

For x=0

substitute in the linear equation and solve for y

$y=-2(0)-3\\y=-3$

The y-intercept is the point (0,-3)

Part 2) What is the slope (in fraction form)?

we have

$y=-2x-3$

This is the equation of the line in slope intercept form

$y=mx+b$

where

m is the slope or unit rate

b is the y-intercept

$m=-2$

In fraction form is

$m=-\frac{2}{1}$

The slope is negative, that means, is a decreasing function (as the x-values increases the y-values decreases)

Part 3) Graph the line

To graph the line we need two points

From the y-intercept (0,-3) use the slope to find your next point

The slope is -2, so you will rise -2 (2 units down) and run 1 (1 unit to the right).

The next point is (0+1,-3-2) -----> (1,-5)

Plot the points (0,-3) and (1,-5), connect them and graph the line
