The graph of the revenue function f(x) = -2x2 + 100x is shown to the left. In the function, revenue is dependent
on the number of items sold, x. How do the
mathematical and reasonable domains compare?
O
mathematical: -- < x < 0
reasonable: 0 sxs 1250
O mathematical: x = 1250
reasonable: 0 < x < 50
O mathematical: -- < x < .0
reasonable: 0 < x < 50

O mathematical: x < 1,250
reasonable: 0 < x < 1,250
Algebra

step-by-step explanation:

we are given

since, we have to isolate x on anyone side

so, we can move all x terms on one side

subtract both sides by 2x

add both sides by 9

divide both sides by 4

we get

the total estimated nappy use.=10,500,000

step-by-step explanation:

given that on an average the average baby uses 3528 napkins.

in a particular year 2014, the number of births were 299697 in new south wales.

rounding off the number of births to the nearest hundred thousand we have

no of birtsh = 300000

also rounding off the average usage to nearst thousand we get

average use of a baby = 3500

hence total number of nappy estimated to be used = 3500x300000

= 10,500,000

answer is 10,500,000 nappies

step-by-step explanation:

$75.00

step-by-step explanation:

i = prt

i = 1,5000 * 0.025 * 2

i = 75
