Step-by-step explanation:
hello:D ... ..... .......
The number of roots of a quadratic function can be determined from its discriminant.
If Disc> 0, the function has two distinct roots
If Disc = 0, the function has a repeated root
If Disc < 0, the function has no real root.
The discriminant can be calculated as:
Disc = b² - 4ac
For the given equation:
Disc = 9 - 4(2)(1) =1
Since the value of discriminant is positive, the function will have two distinct roots.
So, the answer to this question is option B
Answer:
30.53
Step-by-step explanation:
24 x 1.06 = 24.44 (6% tax added to 24)
24.44 x 1.20 = 30.53 (20% tip added on top)
9 I think, soo sorry if i'm wrong...
