9514 1404 393

Answer:

  91 rad/s

Step-by-step explanation:

The relationship between angular velocity (ω) and constant angular acceleration (ω') is ...

  ω(t) = ω0 + t·ω'

  ω(0.25) = 95 = ω0 + 0.25(16)

  95 -4 = ω0 = 91 . . . rad/s

The initial angular speed was 91 radians per second.

23. The answer is D. If you multiply 0.8 by 5 you get 4 meters which means it would take 5 minutes. Multiplying it by 5 will give you a whole number therefore easier to find on the graph.

24. The answer is G. The square root of 5 is 2.23 and the square root of 2 is 1.4

Find the measure of unknown angle​
Bumek [7]

Answer:

The angle in the upper right quadrilateral corner = 68 degrees because vertical angles are equal.

Angle Y = 68 (opposite quadrilateral angles are equal).

All quadrilateral angles add to 360 so:

68 + 68 + x + z = 360 = 292

angle X + Z = 292

Therefore angle x = angle z = 146

Solve for x <br> This is also an octagon if it helps!
Karo-lina-s [1.5K]

Answer:

x = 10

Step-by-step explanation:

it has 8 sides so:

total interior angle degrees = (180° x 8 sides) - 360° = 1080°

11x + 14 + 4x + 87 +2x + 70 + 4x + 31 + x + 92 + 3x + 167 + 5x + 48 + 2x + 251 = 1080°

combine like terms:

32x + 760° = 1080°

subtract 760° from both sides of the equation:

32x = 320°

divide both sides by 32:

x = 10

A plane is travelling at 180 metres per second. How many minutes will it take for the plane to travel 800km? Give your answer in
Pavel [41]

Answer:

79 minutes

Step-by-step explanation:

A plane is travelling at 180 meters per seconds

Convert to km/hr

180× 18/5

= 648 km/hr

Since 648 km equals 1 hour then the number of minutes required for the plane to travel 800 km is

= 1/648 × 800

= 1 hour 19 minutes

Conver the time to full minutes

60 minutes = 1 hour

= 60+19

= 79 minutes

Hence the minutes required for the plane to travel 800km is 79 minutes
