If the discriminant of a quadratic equation is equal to -8 , which statement describes the roots?
GaryK [48]

Answer: There are no real number roots (the two roots are complex or imaginary)

The discriminant D = b^2 - 4ac tells us the nature of the roots for any quadratic in the form ax^2+bx+c = 0

There are three cases

  • If D < 0, then there are no real number roots and the roots are complex numbers.
  • If D = 0, then we have one real number root. The root is repeated twice so it's considered a double root. This root is rational if a,b,c are rational.
  • If D > 0, then we get two different real number roots. Each root is rational if D is a perfect square and a,b,c are rational.

Find the tan A and sin B exactly.
Rudik [331]

Answer:

  • B - tan A = 4/3, sin B = 3/5

Step-by-step explanation:

<u>First, lets find the length of the third side</u>

  • b = √15² - 12² = √225 - 144 = √81 = 9

<u>Now, lets get Tan A and Sin B</u>

  • Tan A = 12/9 = 4/3
  • Sin B = 9/15= 3/5

Correct option is B

Dvinal [7]
B is called "the vertical intercept" and is the value of y when x = 0.  Something like an initial value!
