0% because the deck only has 9s, 10s, jacks, queens, kings, and aces. There is no others cards accept those. So you cannot get a 4 of hearts because it’s not in the deck.

Write the quadratic equation in standard form for the following equations <br> (7,4);(-2,1);(1,9)
ladessa [460]

Answer:

y=-\frac{7}{18}x^2+\frac{41}{18}x+\frac{64}{9}

Step-by-step explanation:

We need to write a quadratic equation so we can use standard quadratic equation:

y=ax^2+bx+c

Plug the given points to get three equations.

for (7,4), we plug x=7 and y=4

4=a(7)^2+b(7)+c

4=49a+7b+c ...(i)

similarly using other two points, we get:

1=4a-2b+c ...(ii)

9=a+b+c ...(iii)

Now we solve those three equations by any method like substitution, or matrices or by any method and get:

a=-\frac{7}{18},\ b=\frac{41}{18},\ c=\frac{64}{9}

Now plug these values into y=ax^2+bx+c, we get final equation as:

y=-\frac{7}{18}x^2+\frac{41}{18}x+\frac{64}{9}
