Answer: It has two distinct real zeros.
Step-by-step explanation:
The formula that is used to calculate the discriminant of a Quadratic function is the one shown below:
![D=b^2-4ac](https://tex.z-dn.net/?f=D%3Db%5E2-4ac)
In this case you have the following Quadractic function provided in the exercise:
![f(x)=6x^2 +10x-1](https://tex.z-dn.net/?f=f%28x%29%3D6x%5E2%20%2B10x-1)
Let's make it equal to 0:
![0=6x^2 +10x-1](https://tex.z-dn.net/?f=0%3D6x%5E2%20%2B10x-1)
You can identify that:
![a=6\\\\b=10](https://tex.z-dn.net/?f=a%3D6%5C%5C%5C%5Cb%3D10)
Knowing these values, you can substitute them into the formula and then evaluate:
![D=10^2-4(6)(-1)\\\\D=124](https://tex.z-dn.net/?f=D%3D10%5E2-4%286%29%28-1%29%5C%5C%5C%5CD%3D124)
Therefore, since:
![D>0](https://tex.z-dn.net/?f=D%3E0)
You can determine that the it has two distinct real roots.
Answer:
Step-by-step explanation:
[2,∞)
The length of DE is 39 and the length of EF is 36 because we can see from side AC and DF that triangle DEF is just triangle ABC dilated by 3.
Answer:
285 Words
Step-by-step explanation:
If in 1 minute he can type 30 words
, then in 9.5 min he can type 30 x 9.5 = 285.0 = 285
So, Nick can type 285 words in 9.5 minutes.
Hope this Helps!
