An architect is designing a water fountain for a park she uses the given function to model the water jets flowing from the fountain nozzles where h(x) gives the height of the water jet in feet x feet from its starting point. Select two adjacent columns that show an interval with an average rate of change of -0.3.h(x)=-1/20x^2+x+15

1 + (6 / x - 1)

step-by-step explanation:

divide using polynomial division.

$2416.6

step-by-step explanation:

per hour = $ 25

total work time = 35

commission = 15%

total she has to make = $ 4,500

let she sold x dollar products

so her commission will be 15 % of x

now

total = weekly basic pay + commission

4500= (25*35) + 15 % of x

4500=875 + * x

4500-875 =   * x

3625= * x

multiplying wwith 100 on both sides gives

36250 = 15 x

now

x =  

x= $2416.6
