What you need to know for this case is that the linear velocity is defined as the product of the angular velocity by the radius.
 We have then:
 v = w * r
 Substituting the values:
 v = (45) * (15) = 675
 v = 675 cm / min
 answer:
 The linear speed, in cm / min, of a point on the rim of the record is:
 v = 675 cm / min

Find the distance between (-8,7) and (13,-1)​
grin007 [14]

Answer:

22.4722

Step-by-step explanation:

To answer this question we need to use the distance formula. The distance formula is as follows:

d = \sqrt{(x2 - x1)^2+(y2 - y1)^2}

Now, let's identify what each variable is:

x2 = 13

x1 = -8

y2 = -1

y1 = 7

Next, let's put these into the equation:

d = \sqrt{(13 - (-8))^2 + (-1 -7)^2}

Time to solve the equation:

d = \sqrt{(21)^2+(-8)^2} \\d = \sqrt{441 + 64} \\d = \sqrt{505} \\d = 22.4722

Therefore, the distance between the points of (-8,7) and (13,1) is 22.4722.
