OK so you would treat the absolute value line kind of like parentheses. First you would do the work inside then take the absolute value. In case you don't know absolute value is how far something is from zero

Since the absolute value of anything is always a positive number, you have the absolute value of 10 minus negative 43, which is really 10 + 43. You now have 53, since a double negative in math is a positive. Now youre left with |53|, and so your answer is the absolute value of positive 53, meaning your answer is 53.

The rear wheel of a lawn tractor has a 20-inch radius. Find the angle (in radians) through which a wheel rotates in 23 seconds i
Minchanka [31]

Answer:

263.12 radians

Step-by-step explanation:

The length of the rear wheel is given by:

L=2\pi r\\L=40\pi

The distance traveled by the lawn tractor in 23 seconds is:

d=13\frac{miles}{hour} *63360\frac{inch}{miles}*\frac{1\ hour}{3600\ seconds}*23\ seconds\\ d=5,262.4\ inches

The angle through which a wheel rotates is given by:

A=\frac{d}{L}*2\pi \\A=\frac{5,262.4}{40\pi}*2\pi\\A=263.12\ radians

The wheel rotates through a 263.12 radians angle.

Find the slope of the line that contains the points:(-6, 3) and (-4,5).
Rus_ich [418]

Answer:

Slope:1

Step-by-step explanation:

When finding the slope from 2 points, you subtract them y/x

(-6,3)

(-4,5)

-2,-2

Slope: (-2,-2)=1

y=x+b

Insert on of the the points, in this case, I will choose -6,3

3=-6+b

b=9

So slope intercept form, the answer will be y=x+9.

Since you are just finding the slope, the answer is just 1.
