Answer:
24.5
Step-by-step explanation:
1) The angular speed is approximately 12.566 radians per second.
2) The linear speed of a point on the edge of the disk is 1.257 meters per second.
<h3>What are the angular speed and the linear speed of a spinning disk?</h3>
1) Herein we have a disk that spins at constant angular speed (ω), in radians per second, whose magnitude is found dimensional analysis and unit conversions:
ω = 120 rev / min × (2π rad / 1 rev) × (1 min / 60 s)
ω ≈ 12.566 rad / s
The angular speed is approximately 12.566 radians per second.
2) The linear speed (v), in meters per second, on the edge of the disk is described by the following formula:
v = R · ω
Where R is the radius of the spinning disk, in meters.
If we know that R = 0.1 m and ω ≈ 12.566 rad / s, then the linear speed is:
v = (0.1 m) · (12.566 rad / s)
v = 1.257 m / s
The linear speed of a point on the edge of the disk is 1.257 meters per second.

Answer:
A. g + (g + 14) = 82
Bonus: Gary trained 48 dogs. Triana trained 34.
Step-by-step explanation:
Since Gary trained 14 MORE dogs, anything with a minus sign is definitely wrong. As a result, B & C are eliminated. D is also eliminated because that simplifies to 2g + 28 = 82, which signifies Gary trained 28 more dogs, which is not true. That leaves A as our answer.
g + g + 14 = 82
<em>Combine g & g to get 2g.</em>
2g + 14 = 82
<em>Subtract 14 from both sides.</em>
2g = 82 - 14
2g = 68
<em>Divide both sides by 2.</em>
g = 68/2
g = 34
With that, we now know Triana trained 34 dogs. Add 14 to that, and you get 48 dogs, which is how many Gary trained.
3(-1) + 2= -1. replace x with -1
3(-3) + 2 = -9 + 2 = -7 replace x with -3
3(0) + 2 = 0 + 2= 2 replace x with 0
3(1)+2= 3+2= 5 replace x with 1
3(2)+2= 6+2= 8 replace x with 2
