#1
- The limit tends to 0
- Hence c=0
- Here limit tends to 1
- Hence c=1
- Here x tends to infty.
- c=infty
For the fourth one limit also tends to zero
The answer would be 400,000.
The answer you want would be -120
b/c 200/5 is 40 so -3*40 is <em>-120</em>
This is important because if you were to answer in complex fractions instead of its simplest form, you would have a tough time multiplying complex fractions together. You would get a HUGE denominator or numerator, which makes things difficult. It is important to write a fraction in its simplest form because of exactly that; making things simple. Would you rather multiply 64/132*64/132 or 1/2*1/2?
