30 in the ratio 3:2
3:2....added = 5

3/5(30) = 90/5 = 18
2/5(30) = 60/5 = 12

so 30 in the ratio 3:2 is 18:12
=======================
31.50 in the ratio 3:4
3:4...added = 7

3/7(31.50) = 94.5/7 = 13.50
4/7(31.50) = 126/7 = 18

31.50 in the ratio 3:4 is 13.50:18

In 1995, a public library had 16,000 books on its shelves. In 1999 the library had 19,000 books. Find the average rate of change
marusya05 [52]

Answer:

<u><em>750 Books Per Year</em></u>

Step-by-step explanation:

For this problem, we will be using the standard Rate Of Change formula that we use for graphs:

<em>RoC = (y2 - y1) / (x2 - x1)</em>

y = books

x = year

By plugging in the given values:

RoC = (19000 - 16000) / (1999 -1995)

RoC = 3000 / 4

<u>RoC = 750</u>

Identify the equation of the circle that has its center at (-16, 30) and passes through the origin.
s2008m [1.1K]
The general equation of the circle is:

(x -xo)^2 + (y - yo)^2 = r^2

Where xo,yo are the coordinates of the center and r is the radius of the circle.

Here (xo,yo) is (-16,30) and you can find the radius.

You can find the radius using the equation of the distance (Pythagoras) between the center (-16,30) and any point on the circunference. Here use (0,0)

r^2 = (-16 - 0)^2 + (30 - 0)^2 = 1156

Then, the equation is>

(x - (-16) )^2 + (y - 30)^2 = 1156

=> (x + 16)^2 + (y - 30)^2 = 1156.   <----- answer
