Answer:
Right triangle
Step-by-step explanation:
90 degrees means that it's a right angle
Answer:
2 real solutions
Step-by-step explanation:
We can use the determinant, which says that for a quadratic of the form ax² + bx + c, we can determine what kind of solutions it has by looking at the determinant of the form:
b² - 4ac
If b² - 4ac > 0, then there are 2 real solutions. If b² - 4ac = 0, then there is 1 real solution. If b² - 4ac < 0, then there are 2 imaginary solutions.
Here, a = 6, b = -20, and c = 1. So, plug these into the determinant formula:
b² - 4ac
(-20)² - 4 * 6 * 1 = 400 - 24 = 376
Since 376 is clearly greater than 0, we know this quadratic has 2 real solutions.

Answer:
20% of players are left-handed
Step-by-step explanation:
First, find how much each player is worth percent-wise
100 / 80 = 1.25
Then find out how much percent of players that makes up
1.25 x 16 = 20
The answer is 20% of players are left-handed, to check it you could do
80 * 0.2 = 16
<em>(80 = total players, 0.2 = 20%, 16 = total left handed players)</em>
1st payment = $1451
2nd payment = $1451 (1/3) = $483.67
3rd payment = $1452(1/3)² = $161.22
4th payment = $1451(1/3)³ = $53.74
Total after 4 payments = 1451 + 483.67 + 161.2 + 53.7 = $2149.63
Answer: C. $2,149.63
