Answer:

5.10 m/s

The "m/s" means "meters per second". The value is approximate.

===============================================================

Explanation:

Recall that

distance = speed*time

which we can isolate the speed to get

speed = distance/time

You divide both sides by time and flip both sides.

So that explains why for example Nate's speed is (50 meters)/(10 seconds) = 5 m/s. The other runners are calculated the same way.

You should get the following speeds for each runner

Tray = 4.167 m/s approximately

Riley = 6.25 m/s

Sara = 5 m/s

Nate = 5 m/s

Only Tray's value is approximate since the decimal number goes on forever. I rounded to three decimal places. The other values are exact.

Once we have these four speed values, we add them up and divide by 4 to find the average speed overall of the group.

(4.167+6.25+5+5)/4 = 5.10425

The average speed of the team is roughly 5.10 m/s

--------------------

Extra info (optional section)

To convert from m/s to mph, you will multiply by roughly 2.237

For example, 5 m/s turns into 5*2.237 = 11.185 mph, which is approximate.

The length, width, and height of a rectangular box are represented by 2x, 3x + 1, and 5x - 6, respectively. When the volume is e
natali 33 [55]

Answer:

The coefficient of the 2nd term is - 26

Step-by-step explanation:

  • <em>Standard form of polynomial means its terms are ordered from greatest exponent to smallest exponent </em>
  • <em>The leading coefficient in polynomial is the coefficient of the first term in a polynomial in standard form</em>

∵ The length, width, and height of a rectangular box are

    represented by 2x, 3x + 1, and 5x - 6

∴ l = 2x , w = 3x + 1 , h = 5x - 6

The formula of the volume of a rectangular box is V = l × w × h

∵ V = 2x(3x + 1)(5x - 6)

- multiply the two brackets at first

∵ (3x + 1)(5x - 6) = (3x)(5x) + (3x)(-6) + (1)(5x) + (1)(-6)

∴ (3x + 1)(5x - 6) = 15x² + (-18x) + 5x + (-6)

- Add the like terms

∴ (3x + 1)(5x - 6) = 15x² + (-18x + 5x) + (-6)

∴ (3x + 1)(5x - 6) = 15x² + (-13x) + (-6)

- Remember (-)(+) = (-)

∴ (3x + 1)(5x - 6) = 15x² - 13x - 6

Substitute it in V

∴ V = 2x(15x² - 13x - 6)

- Multiply each term in the bracket by 2x

∴ V = 2x(15x²) - 2x(13x) - 2x(6)

∴ V = 30x³ - 26x² - 12x ⇒ in standard form

∵ The second term in the polynomial is - 26x²

∴ Its coefficient is - 26

∴ The coefficient of the 2nd term is - 26
