Answer:
no
Step-by-step explanation:
It is close, but not exactly a right triangle.
If it were a right triangle, we would have ...
21² +70² = 73²
We have instead ...
441 +4900 ≠ 5329
5341 ≠ 5329 . . . . . . . . not a right triangle


You are essentially asking at this point where is the quadratic function greater than 0. To get the interval find the roots. Between the roots the function is guaranteed to be LESS THAN zero. Everywhere else the function is greater than 0.

Use Vieta's rule to get the roots,

Both roots are the same so no value is less than 0 which means all values except at the point of root are strictly greater, the point of root is at
which means the set for which the quadratic function is greater than 0 is
"all real numbers except 1".
To convert this into interval notation use all numbers up to 1 but not including and all numbers after 1 but not including,

Hope this helps :)
Answer:
8/12 or 66.6%
Step-by-step explanation:
If we have 12 sides to a die then there are 12 possible outcomes, as a result if the dice would have a total of 8 sides that is either 5 or more (5,6,7,8,9,10,11,12,) that means 8/12 of the dice would be a satisfy the outcome we are looking for and 8/12 is around 67%
