Question 1196398: Please help with the homework:
The graph of the function F, which is a straight line defined by y= mx +k. Such that the point V (3,-4) lies on the line, and the graph of a function g, which is a parabola with vertex R(3,2). The straight line and the parabola intersect at P and Q. The point S and T lie on the parabola and straight line respectively, between P and Q. The line ST is parallel to the y axis.
1. Sketch the graph
2. Calculate m and k hence write down the equation of F.
3. Find the maximum length of ST. At what value of x will ST be at its longest?
4. What is the equation of the circle with center P and radius equal to the distance from P to the origin?
5. What is the equation of the hyperbola through the point?
6. Use the graph to solve the inequality (f,g)x<0.

You can put this solution on YOUR website! .
From the post, it is IMPOSSIBLE to answer part (2), since there is no necessary and sufficient data for it.
Also, it is impossible to answer all other questions/parts - - - due to the same reason.
Try to make a sketch on your own, based on the text, and you quickly will get to the same conclusion.
In part (5), the term "hyperbola" suddenly appears without any connection
with the rest of the text. It makes a special " deep " impression.
What is interesting, in this problem each word, taken separately, is correct English term.
but taken together, they do not make any sense.
As is, the " problem " is a FAKE and is only good to throw it to the closest garbage bin.
Don't be offended by me for telling you the truth.
----------------
If it is your teacher/professor gave you this assignment, then please pass this information to him.
If the problem came from another source, then let them know about this casualty.
If you created this problem on your own, then please do not compose such absurdist problems in the future.

Hello, I got an " empty " comment, expressing your dissatisfaction.
Could you tell me please, what precisely caused your displeasure?
The fact that I told a truth to you ?
Actually, I deserve great " THANKS " from you (seven times), but you, unfortunately, do not understand it.
