(Problem of the Week)
ira [324]

Answer:

He won 13 times and lost 1 time

Step-by-step explanation:

divide 67 by 5 so 67÷5 you would get 13.4 you take the whole number 13 and multiply it by 5 and that will get you to 65 so then you only have 2 left over and if you lose you get 2 point so therefore you know that he lost only once

(13•5)+2=67

(a) The curve with equation y2 = x3 + 3x2 is called the Tschirnhausen cubic. Find an equation of the tangent line to this curve
Dafna1 [17]

Answer:

  (a)  y = 9/4x -1/4

  (b)  (-2, -2), (-2, 2)

  (c)  see below

Step-by-step explanation:

(a) The derivative can be found from ...

  2y·y' = 3x² +6x

At (x, y) = (1, 2), this is ...

  4y' = 9

  y' = 9/4

so the equation of the tangent is ...

  y = (9/4)(x -1) +2

  y = (9/4)x -1/4

__

(b) At y' = 0, we have ...

  0 = 3x² +6x = 3x(x +2)

This says y' = 0 at x=0 or x=-2. (x = 0 is an extraneous solution.)

At x = -2, we have ...

  y² = (-2)³ +3(-2)² = -8+12 = 4

  y = ±2

So, the horizontal tangent points are (x, y) = (-2, ±2).
