Answer:
Step-by-step explanation:
The discriminant is part of the quadratic formula. If the value of the discriminant is less than 0, you have 2 imaginary solutions; if the discriminant is equal to 0, you have 1 real solution; if the discriminant is greater than 0, you have 2 real solutions.
The discriminant is , which for us, looks like this:
which simplifies to -63. That means that the solutions are imaginary...not real at all. So in answer to your question, there are no real zeros at all.

<u>Answer:</u>
0.0005 oz
<u>Step-by-step explanation:</u>
Usually, the greatest number that is allowed for approximation, assuming that the number itself is obtained by approximation, is the greatest possible error of it.
It is normally half the place value of the last digit in a number.
Like here we have oz which is equal to
oz. The last digit is 5 which is at the thousandth place (0.001) so the greatest possible error for this would be its half.
= 0.0005 oz
