Answer:
Step-by-step explanation:
I'm assuming you meant to type in
because you can only have removable discontinuities where there is a rational (fraction) function. Begin by factoring both the numerator and denominator to
and cancelling out like terms would have us eliminating the (x + 3). That is where there is a removable discontinuity. It leaves a hole. The other discontinuity, (x + 1) doesn't cancel out so it is a non-removable discontuinity, which is a vertical asymptote.
The removable discontinuity is at -3. There is no y value at x = -3 (remember there's only a hole here), because -3 causes the denominator to go to 0 and we all know that having a 0 in the denominator of a fraction is a big no-no!!!
The time taken for her trip is 3 hours.
<h3>Given that</h3>Koto’s average velocity along her route was 4. 5 m/s.
She started at her house and traveled 15,000 meters north, 5,000 meters east, 20,000 meters south, and then 5,000 meters west.
<h3>We have to determine</h3>What was the time of her trip?
<h3>According to the question</h3>She started at her house and traveled 15,000 meters north, 5,000 meters east, 20,000 meters south, and then 5,000 meters west.
<h3 /><h3>The calculation of such a trip of Koto can be done by applying the known formula of Time when the Speed is multiplied by Distance to compute the actual time of the trip.</h3>The formula to calculate the time for her trip is;
- Using the formula above, the commute in each direction is added as 45000 meters or 45 kilometers.
- If Koto's average speed is 4.5 meters per second, then she travels roughly 270 meters in one minute.
Substitute all the values in the formula;
Converting minutes into hours,
Hence, the time taken for her trip is 3 hours.
