What is the General form of the parabola of (y-3)^2=6(x+8)
MatroZZZ [7]

Answer:

x = 1.5t^{2}  , y = 3 + 2at.

Step-by-step explanation:

For the parabola Y^{2} = 4aX ,

General form will be

(X = at^{2} , Y = 2at) ,

Thus , for the parabola (y-3)^{2} = 6(x +8)

Here , a = 1.5 and Y from the above equation should be substituted by y - 3 and X must be substituted by x + 8. After substitution of the same we can  use the general equation formula for this parabola also.

Thus , general equation comes out to be :-

x + 8 = 1.5t^{2} , y - 3 = 2at

x = 1.5t^{2}  , y = 3 + 2at.

Answer:

<em>Expected Payoff ⇒ $ 1.50 ; Type in 1.50</em>

Step-by-step explanation:

Considering that 1 out of the 100 tickets will have a probability of winning a 150 dollar prize, take a proportionality into account;

100 - Number of Tickets,\\1 - Number of Tickets You Can Enter,\\\\1 / 100 - Probability of Winning,\\$ 150 - Money Won,\\\\Proportionality - 1 / 100 = x / 150, where x - " Expected Payoff "\\\\1 / 100 = x / 150,\\100 * x = 150,\\\\Conclusion ; x = 1.5 dollars

<em>Thus, Solution ; Expected Payoff ⇒ $ 1.50</em>
