Find and identify the traces of the quadric surface x2 + y2 − z2 = 36 given the plane. x = k Find the trace. Incorrect: Your ans

AlekseyPX

Answer:

Hyperbola.

Step-by-step explanation:

We start from the function:

$x^{2} +y^{2} -z^{2} =36$

We may get the traces if we cut the surface in planes x=k. This is equivalent to replace x for k:

$k^{2}+y^{2} -z^{2}=36\\y^{2} -z^{2}=36-k^{2}$

The last equation is the equation of an hyperbola, which varies its characteristics depending on K (the plane cut).

A car travels 14km in 25mins . Find out how far the car can travel in 5 hours if the speed remains the same ?

jekas [21]

<h3><u>Answer :- </u></h3>

168 km ...

<h3><u>Explanation :- </u></h3>

It is given that the car travels 14km in 25 minutes..

Now , assume that the distance the car travel in 5 hours be x..

Since 1 hour = 60 minutes..
5 hours = 300 minutes ..

• Thus , The two given statements are :-

14km -----------------> 25 minutes..
And, x km -------------> 300 minutes..

The distance travelled by car and the time taken by the car is directly proportional to each other....

$\frac{14}{25} = \frac{x}{300}$

$= x = 168km$

• Hence , Car can travel 168km in 5 hours ..

Hope this helps you :)
