Answer:
A
Step-by-step explanation:
Recall that for a quadratic equation of the form:
The number of solutions it has can be determined using its discriminant:

Where:
- If the discriminant is positive, we have two real solutions.
- If the discriminant is negative, we have no real solutions.
- And if the discriminant is zero, we have exactly one solution.
We have the equation:

Thus, <em>a</em> = 2, <em>b</em> = 5, and <em>c</em> = -<em>k</em>.
In order for the equation to have exactly one distinct solution, the discriminant must equal zero. Hence:

Substitute:

Solve for <em>k</em>. Simplify:

Solve:

Thus, our answer is indeed A.
Answer:
Profit = $6
Step-by-step explanation:
The box of apple that the man bought contained 100 apples.
These 100 apples were gotten for $44
Then he sold the 100 apples for $0.5 each.
So sales price = 0.5 * 100 = $50
To know if he made profit or loss.
Sales price - cost price
$50 - $44
= $6
This man made profit of $6 from the sales of the apples from the calculation above.
