BARSIC [14]

Answer:

  • (3, 21), (6, 12)
  • -3
  • y -21 = -3(x -3)  ⇒  y = -3x +30
  • 30 minutes; 3 minutes

Step-by-step explanation:

a) The two marked points have coordinates (days, minutes) = (3, 21) and (6, 12).

__

b) The slope is the vertical change (rise) divided by the horizontal change (run). For these two points, that is ...

  rise/run = (12-21)/(6-3) = -9/3 = -3 = slope

__

c) The point-slope form of the equation for a line is ...

  y -k = m(x -h) . . . . . . for slope m through point (h, k)

Using the first point and the slope we found, this is ...

  y -21 = -3(x -3) . . . . . point-slope form

Add 21 and eliminate parentheses:

  y = -3x +9 +21

  y = -3x +30 . . . . . . . . collect terms; slope-intercept form

__

d) The initial time is the time corresponding to day 0, the value of y when x=0. It is 30 minutes.

The slope in part (b) tells us the time decreases by 3 minutes per day.

Marian is making accessories for the soccer team. She uses 888.44 inches of fabric on headbands for 36 players and 2 coaches. Sh
ki77a [65]

Answer:

23.38 inches of fabric was used for headband for each player.

9.43 inches of fabric was used for wristband for each player.

Step-by-step explanation:

Given that:

Total fabric used on headbands = 888.44 inches

Total number of players = 36

Total number of coaches = 2

Total number of people for whom headbands were made = Number of players + Number of coaches = 36 + 2 = 38

Amount of fabric used for each one = Total fabric used for headbands divided by Total number of people

Amount of fabric used for each one = \frac{888.44}{38}=\bold{23.38\ inches}

Similarly,

Total fabric used on wristbands = 339.48 inches

Total number of players = 36

Amount of fabric used for each one = Total fabric used for headbands divided by Total number of players

Amount of fabric used for each one = \frac{339.48}{36}=\bold{9.43\ inches}
