Part D is what i meant sorry

 

[Yours Truly]

no the tangents questions the inequality that satisfiys k , sorry i know the tangents its the inequalities that satsifiyes k im have a problem with

In that case you have to find the line's equation!
The line that cut's the graph at 3 places has 3 answers. "...where k has 3 values"

Let's assume there is a graph and the line y=3 cuts the graph at 3 places. The value of k is 3

As for the inequality... ASSUME that

y=1 has 1 answer
y=2 has 2 answers
y=3 has 2 answers
y=4 has 2 answers
y=5 has 2 answers
y=6 has 1 answer

"...where k has 3 values"
Ans: 1>k>6


In this case k>1.85 as any value above 1.85, when drawn as a line, has 3 answers

Hello guys, please can anyone tell me to how many decimal places our answers should be and do we need to round our answers? thank you

i have doubt in question number 10, paper 2 may/june 2008

this qsn??----The height, h metres, of a telegraph pole is 12 metres correct to the nearest metre.
Complete the statement about the value of h.

it just ask for the lower and upper bound of 12m

that is---l.B===12-o.5=11.5
U.B==12+0.5=12.5

ans == 11.5 <or =h<12.5
