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 in the number of books per year. *

750 Books Per Year

Step-by-step explanation:

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

RoC = (y2 - y1) / (x2 - x1)

y = books

x = year

By plugging in the given values:

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

RoC = 3000 / 4

RoC = 750

22 and 22

step-by-step explanation:

10 plus 12 equals 22.

12 plus 10 also equals 22 because regardless of what order they're in, they're gonna equal the same thing.

dc=6 square root of 3 and ac is 12 square root 3

c and d

step-by-step explanation:

square root of 3/2 = 18/c

cross multiply to get 18*2=√3*c

36/√3 * √3/√3 = c

c= 36*√3/3

c=12√3
