Answer:
C
Step-by-step explanation:
Remember that we can use the discriminant to determine the amount of roots that a quadratic function has.
If the determinant equals 0, then we only have one real root.
Our function is given by:

Then the discriminant will be:

We only have one real root, thus our discriminant must be 0:

Solve for b:

Thus:

The answer is both II and III.
The final answer, then, is C.

Answer:
$25.31
Step-by-step explanation:
If you multiply 33.75 by .75 you get your answer.
To solve 3.45 x 10⁹, you have to move the decimal point of 3.45 nine times to the right(---->). Once you do that, you get 3450000000. To solve 0.5 x 10⁴, you have to move the decimal point of 0.5 four times to the right. That equals 5,000. Now the final question is: How many times bigger is 3450000000 than 5,000. So, you divide 3450000000 by 5,000. That equals 690000.
690,000 times bigger than 0.5 x 10⁴
You didn't supply a list. The so-called rigid transformations of translation, rotation and reflection create congruent triangles.
Generally it's dilation by a factor about a point is preserves similarity but not congruency. Any transformation which includes such scalings but is otherwise rigid also preserves similarity but not congruency.
