Let x^2+50=0
solve for x first.
x^2=-50
x=+-√-50
Write that as a complex number
x=+-√50i
x=√50i or x=-√50i
Hope I helped :)
Answer:
The triple is 9, 12, 15
The hypotenuse is 15.
Step-by-step explanation:
Pythagorean Theorem Formula: a²+b²=c² where a & b are the short legs and c is the hypotenuse.
9²+b²=(b+3)²
81+b²=(b+3)²
Small list of the Pythagorean Triples that contain 9:
9,12,15
9,40,41
So as you can see, there are only 2 examples in my list that contain 9 in them. The only one that fits our criteria is the triple, 9, 12 and, 15
You don't need to use the Pythagorean Formula for this as I have just proved.
3% = 3/100 = 0,03
When it's compount interest it's 1,03 because you gain 3% more from what you already have.
All you need to do
1,03•2000=2060$ for the first year
And then for the second year, you take the actual amount after one year of 3%
1,03•2060=2121,8
After two years, there will be 2121,8$
