Answer:
1.the corresponding angles are propositional
2.the corresponding sides are proportional
There would be about a 14.3% chance of being able to see it
30 minutes / 210
.1428 =
14.3%
Answer:
It should take somewhere between 8 to 9 minutes to decay until there are 30 grams remaining.
Answer:
- -6x² - 6 = -7x - 9
- -6x² + 7x - 6 + 9 = 0
- -6x² + 7x + 3 = 0
- 6x² - 7x - 3 = 0
<u>Discriminant:</u>
- D = (-7)² - 4*6*(-3) = 49 + 72 = 121
<u>Since D > 0, there are 2 real solutions:</u>
- x = (- (-7) ±√121 )/12
- x = (7 ± 11)/12
- x = 1.5, x = -1/3
Just simplify?
Than your answer should be
