Answer:
<em>x=11</em>
Step-by-step explanation:
Answer:
To convert a fraction to a percent we take the fraction and multiply it by 100
If we want to convert 1/2 to a percent:
1/2 × 100 = 50%
Or we can convert the fraction to a decimal and then multiply it by 100:
1/2 = 0.5 = 0.5 × 100 = 50%
The roots of a quadratic equation depends on the discriminant 
.
- If
, the quadratic equation has two real distinct roots, and it crosses the x-axis twice. - If
, the quadratic equation has one real root, and it touches the x-axis. - If
, the quadratic equation has two complex roots, and it neither crosses nor touches the x-axis.
---------------------
A quadratic equation has the following format:
It's roots are:
Thus
They are given by:
The discriminant is .
- If it is positive,
, and thus, the quadratic equation has two real distinct roots, and it crosses the x-axis twice.
- If it is zero,
, and thus, it has one real root, and touching the x-axis.
- If it is negative,
is a complex number, and thus, the roots will be complex and will not touch the x-axis.

Given:
P = 200k - 500
A) To determine the constraints on profit and the value of the number of knives sold, k, let P = 0
P = 200k - 500
0 = 200k - 500
solve for k,
k = 2.5 knives or 3 knives
to answer this it's simple
the answer is 20,000
