Answer:
15.66
Step-by-step explanation:
GO GO POWER RANGERS
Distribute 1/2 throughout the set of parenthesis
1/2 · x = 1/2x
1/2 · 12 = 6
1/2x + 6 = 4x -1
subtract 6 on both sides of the equation
1/2x = 4x - 7
subtract 1/2x by 4x
4x - 1/2x = 7/2x
7/2x = -7
isolate x by dividing both sides by 7/2
Which is actually multiplying by the reciprocal, which is 2/7
-7 · 2/7 = -14/2 = -7
x = -7
So, only one answer/solution
The answer is:
7/8
have a nice day :)
Answer:
- angular speed: 61.3 radians/s
- tangential speed at .193 m: 11.8 m/s
Step-by-step explanation:
The forward speed of the center of the tire with respect to the ground is the same as the tangential speed of the tire at its full radius of 0.315 m, relative to the axle.
The angular speed of the tire is the ratio of tangential speed to radius:
(19.3 m/s)/(0.315 m) ≈ 61.27 radians/s
The tangential speed at any other radius is the product of angular speed and radius. At a radius of 0.193 m, the tangential speed is ...
(0.193 m)×(19.3 m/s)/(0.315 m) ≈ 11.825 m/s ≈ 11.8 m/s
2x^2 + 16x - 10 = 0
2(x^2 + 8x) - 10 = 0
2 [(x + 4)^2 - 16 ]- 10 = 0
[(x + 4)^2 - 16 - 5 = 0
(x + 4)^2 - 21 = 0
(x + 4)^2 = 21
