Meiling has 1 1/4 liter of orange juice. she drinks 1/3 liter. how much orange juice does she have left?
(extension: if her brother then drinks twice as much as meiling, how much is left? )

remaining juice left when she drink = liter

remaining juice left when her brother drink = liter

Step-by-step explanation:

given data

orange juice = liter

she drink = liter

to find out

How much orange juice does she have left and If her brother then drinks twice as much as Meiling, how much is left

solution

we know total juice is liter and

she drink liter

so remaining juice left is = total orange juice - she drink    ..............1

remaining juice left is = -

remaining juice left is = liter

and

if her brother drink twice so he drink = 2 × she drink

her brother drink = 2 × liter

her brother drink = liter

so

so remaining juice left is = total orange juice - her brother drink

so remaining juice left is =   -

remaining juice left is = liter

the given growth  function for the length of the fish (cm) is

f(m) = 5(1.07)m = 5.35m

where 

m = months

at the end of the study, the length is 9.19 cm. the  time for conducting the study is determined as

5.35m = 9.19

m = 1.7178 months

part a.

the study was performed over a time period  of about 1.72 months. therefore  the domain for  plotting the function is 0 < = m < = 1.72.

note:

if growth  continues at this rate for up to m months, then the domain would be 0< =m< =m.

part b.

the growth function is a linear function.

when m=0, f=0.

therefore the initial growth is zero, which represents the y-intercept.

part c.

assume that the growth function is valid for 0< =m< =9.

the average rate of change of the function is the slope of the linear function, which is 5.35 cm/month.
