Find the domain of the rational expression: x-4/2x-6 1. all real numbers except 3
2. all real numbers except 6
3. all real numbers except O
4. all real numbers except 4

All real numbers except 3

Step-by-step explanation:

Given

Required

Determine the domain

We start by writing the following inequality

Add 6 to both sides

Divide both sides by 2

As such, the domain of x is all real numbers except 3

1) c 2143.6 cm

2) c 113.0 m

3) a 33.5 ft

4)   d 2 cm

5) c 20 mm

6) 180 in

7) d 120 ft

34.5 cm

step-by-step explanation:

generally for a circular segment of angle, θ° and radius r

arc length

= (θ/360) x circumference

= (θ/360) x 2πr

in our case, θ = 60°, π=3.142 and r = 33 cm

substitute into above formula

arc length

= (60/360) x 2(3.142)( 33) = 34.5 cm
