Which of the following are possible discriminants for a quadratic function that crosses the x-axis twice? Check all that apply.
Sedaia [141]

Answer:

1001

1

Step-by-step explanation:

If a quadratic function crosses the x-axis twice, it has two solutions. For a quadratic function in ax^2+bx+c with discriminant b^2-4ac, the following is true:

  • If b^2-4ac>0, then the quadratic has two real solutions
  • If b^2-4ac=0, then the quadratic has one real solution
  • If b^2-4ac, then the quadratic has no real solutions

Therefore, in order to have two solutions, a quadratic's discriminant must be larger than 0. The only two answer choices that satisfy this are 1001 and 1.

A recipe will make 10 pancakes that are 8 inches in diameter. If you decide to
pashok25 [27]
10 pancakes produces 8 inches in diameter. 
The area of 1 pancake is 
Area = pi * r^2
Area = pi * 4^2
Area = 50.27 in^2
Then multiply it by 10
Total area = 502.65 in^2

A smaller pancake
Area = pi * r^2
Area = pi * 2^2
<span>Area = 12.56 in^2

Divide 502.65 by 12.56
= 502.65 / 12.65
= 39.74

So there are 39 pancakes.
