Answer:
Discriminant is greater than zero, so the roots are unequal and real.
Step-by-step explanation:
We use discriminant to find the nature of the roots
discriminant formula is, b^2 - 4ac
13^2 (-4) × 4 × 6 = 169 - 96 ➡ 73 >0 if discriminant greater than 0 that means the roots are real and unequal.

Answer:
Step-by-step explanation:
1. No it does not as the rock will accelerate downwards (because of gravity) but we can also see that at the first second the rock fell 16 feet compared to the 2 to 3 seconds gap where it fell 80 feet (144-64).
2. All the way down to the ground. Each time gap is getting bigger and bigger (it's accelerating) and the gap between 5 and 6 s should be bigger than 4 to 5 and it is not as the rock cannot fall through the ground but only hit the ground
you may have to change the english a bit and english is not my first language
hope this will help
There will be 54 students on the Track team.
1.) 0.09 x 600
2.) 54
To check this answer, follow these steps
1.) 54 divide by 600
2.) 0.09
That means 54 is 0.09% of 600
Remember, sin(|x|)=cos(|90-x|)
so sin(|36|)=cos(|90-36|)=cos(|54|)=cos(54)
answer is C
