For this case we have the following equation:
-16 = 16x ^ 2
Clearing x we have:
-16 / 16 = x ^ 2
x ^ 2 = -1
x = +/- root (-1)
Rewriting:
x = +/- i
Therefore, the solutions are:
x1 = i
x2 = -i
Answer:
this equation has two solutions:
x1 = i
x2 = -i
D.
Because 25 percent is 25/100 or 0.25 therefore 0.25 times N would be 25%. 25N/100 is also correct because it is another way of writing 0.25N. c is also correct because 25% is 1/4

First, we have 14 spores. If they double in 3h, we have 28. When they double in 3h, we have 56, then 112 in the next 3h and so on. To reach the number of 1792 spores, <u>24 hours</u> need to pass.
