Describe the type of solutions for a quadratic equation that has a discriminante of -10

solutions are complex, that is not real

Step-by-step explanation:

The conditions of the solutions from the discriminant are

• If b² - 4ac > 0 then solutions are real and distinct

• If b² - 4ac = 0 then solutions are real and equal

• If b² - 4ac < 0 then solutions are not real

Thus for a discriminant of - 10 the solutions are not real

45

step-by-step explanation:

smple

the answer is b.

step-by-step explanation:

by the trigonometric ratio tangent, tangent equals opposite divided by adjacent.

therefore, tan(50) equals ac/3

multiply each side by 3 to get: ac=3tan(50)

the answer is b.
