Noel and Casey both start at the same place. Noel walks due south and Casey walks due east. After some time has passed, Noel is 6 miles south and Casey is 8 miles east. At this time, Noel is walking at a rate of 2 mph and Casey is walking at a rate of 1 mph. How fast is the distance between them increasing at this time

2.04 miles per hour

Step-by-step explanation:

Given

Noel

Casey

Required

The rate at which the distance increases

Their movement forms a right triangle and the distance between them is the hypotenuse.

At and

The distance between them is:

After 1 hour, their new position is:

New = Old + Rate * Time

And:

So, the distance between them is now:

The rate of change is:

this is answer of 144 cubic meters

first, we define the variables:

x: number of years after 1950

f (x): amount of vinyl sold.

then, with the variables defined, we have:

68594 vinyl records were sold in 1958 > f (8) = 68594

91299 vinyl records were sold in 1961 > f (11) = 91299

38720 vinyl records were sold in 1952 > f (2) = 38720

161743 vinyl records were sold in 1967 > f (17) = 161743
