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.

What is the value of x?<br><br> A. 2 Units<br> B. 3 Units<br> C. 5 Units<br> D. 8 Units
Fudgin [204]

You need the formula for geometric mean for right triangles as it applies to the altitude. For us, that formula will be \frac{BD}{AD}=\frac{CD}{BD} where BD is your altitude. The formula then, filled in accordingly, would be \frac{10}{x}=\frac{4x}{10}. We cross multiply to get that 4x^2=100. Divide both sides by 4 to get x^2=25, so x = 5. Choice C is the one you want.
