Patty has just completed her second semester in college. she earned a grade of upper c in her 4-hour calculus course, a grade of upper d in her 11-hour psychology course, a grade of upper a in her 4-hour physics course, and a grade of upper c in her 2-hour studio art course. assuming that a equals 4 points, b equals 3 points, c equals 2 points, d equals 1 point, and f is worth no points, determine patty's grade-point average for the semester.

b

step-by-step explanation:

multiply terms on numerator/ denominator by (x - 1)

= ← distribute numerator/ denominator

= ← simplify

=

= → b

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.

the answer is d=3.09

the correct answer for this just to make it clear for you guys is 2,3
