Work cycle begins by typing on the body of doc for 30 minutes at 35wpm then takes a 5-min break and works on ref document for 12 min at 20 wpm. sketch a graph of typing rate R(t) as a function of t during one typing

Question

Work cycle begins by typing on the body of doc for 30 minutes at 35wpm then takes a 5-min break and works on ref document for 12 min at 20 wpm.  sketch a graph of typing rate R(t) as a function of t during one typing

anonymous · Answer

I have (30, 35) and (12, 20) so my function is R(t)=5/6t + 10...do I need to include 5 minute breaks somewhere

anonymous · Answer

Then I have to sketch a graph of total number T(t) of words that are typed as a function of time t during one typing cycle...I need several equations with different domains for over next 5 minutes...I'm stuck

amistre64 · Answer

can the f(t) be piece wise?

anonymous · Answer

I would imagine bc I will have several line segments that make up a polynomial line graph

amistre64 · Answer

| 35  ; t=[0,30]
f(t) = |  0   ; t=(30,35)
          | 20  ; t=[35,47]

the given coordinate axis has x values from 0 to 60 and y-axis 0-1500

amistre64 · Answer

like this maybe?

anonymous · Answer

need diagonal lines, right?

amistre64 · Answer

I would say no.  a graph can be disjoint, thre are no rules against that that I am aware of.

amistre64 · Answer

for 35 mins the speed was constant, then dropped to 0 then picked up at 20 at the time intervals indicated is the best I can make out of the problem :)

ok thanks I will keep working
