A CD makes 581/2 revolutions in 2/4 min.<br>Complete the unit rate.
dangina [55]
In 2/4 minutes the number of revolutions a CD makes = 58 ½ <span>                                                                                       = 117/2</span>
Then
In 1 minute the number of revolutions the CD will make = [(117/2)/(2/4) ] * 1 <span>                                                                                         = (117 * 4)/(2 * 2)</span> <span>                                                                                         = 117</span>
So it can seen that the CD revolves at the rate of 117 revolutions per minute. I hope this is the answer you were looking for. The procedure for solving this problem is easy for you to understand i hope.

Which represents the solution(s) of the system of equations, y = x2 – 6x + 8 and y = –x + 4? Determine the solution set by graph
Sergio039 [100]

Answer:

C) (1,3) and ( 4,0)

The intersecting points of two given curves are A( 1,3) and B(4,0)

Step-by-step explanation:

<u><em>Step(i):-</em></u>

Given Parabola  y = x² – 6x + 8  and straight line y = -x +4

      y = x² – 6x + 8   ...(i)

      y = -x +4  ...(ii)

Equating (i) and (ii) equations , we get

  x² – 6x + 8  = -x +4

⇒ x² – 6x + 8  +x - 4 = 0

⇒ x² – 5x +  4 = 0

⇒ x² – 4x -x + 4 = 0

⇒ x ( x-4) -1( x -4) =0

⇒ (x -1) ( x -4) =0

⇒ x =1 and x = 4

<u><em>Step(ii):-</em></u>

Put x = 1 in equation y = -x +4

  y = -1 +4 = 3

The first point A( 1,3)

Put x = 4 in equation y = -x +4

y = -4+4 =0

The second point B(4,0)

<u><em>Final answer:</em></u>-

The intersecting points of two given curves are A( 1,3) and B(4,0)
