Answer:

3.93 m/s

Step-by-step explanation:

In seconds, 42 min, 25 sec (s):

(42 min)(60s/1min) = (42)(60) s = 2,520 s\\2,520 s + 25 s = 2545 seconds

So now, we can calculate the average speed in meters per second (m/s) :

(10,000 meters) / (2545 seconds) = 3.93 m/s

Please let me know if you want this explained further!

Thanks!

Find the equation of the line that is perpendicular to the given line and passes through the given point.
Solnce55 [7]

Answer:

y = 3x + 2

y = 6x – 3

y = 2/3x + 6

y = –1/3x – 4

y = 2x + 1

Correct answer:

y = 3x + 2

Explanation:

Convert the equation to slope intercept form to get y = –1/3x + 2.  The old slope is –1/3 and the new slope is 3.  Perpendicular slopes must be opposite reciprocals of each other:  m1 * m2 = –1

With the new slope, use the slope intercept form and the point to calculate the intercept: y = mx + b or 5 = 3(1) + b, so b = 2

So y = 3x + 2

What is the measure of arc BC?<br> 130<br> 65<br> 32.5<br> 180
ale4655 [162]

Answer:

The measure of arc BC is 130° ⇒ 1st answer

Step-by-step explanation:

In a circle:

  • The measure of an arc is equal to the measure of the central angle subtended by it
  • The measure of an arc is equal to double the measure of the inscribed angle subtended by it
  • Central angles subtended by the same arc are equal in measures
  • Inscribed angles subtended by the same arc are equal in measures
  • The measure of central angle is double the measure of the inscribed angle which subtended by its arc

∵ Angle BDC is an inscribed angle

∵ It is subtended by the arc BC

- By using the 2nd fact above

∴ The measure of arc BC = 2 × the measure of ∠BDC

∵ The measure of angle BDC is 65 degree

∴ The measure of arc BC = 2 × 65°

∴ The measure of arc BC = 130°

The measure of arc BC is 130°
