Answer:
Option C. The open and closed circles are reversed and the graph shifts up.
Step-by-step explanation:
From the graph of the functions (Attached below) you can check that for the interval 0 ≤x<1 the floor function takes the value 0 everywhere, also it has closed brackets at 0 and open brackets at 1.
On the other hand for the interval 0<x≤1 the ceiling function takes the value 1, also it has open brackets at 0 and closed brackets at 1.
For that reason we conclude that the open and closed circles are reversed and the graph shifts up.
we are given
speed is 850mi/h
we know that
1 mile =1609.34 metre
1 hour = 3600 second
now, we can replace 1mi and 1hour

now, we can solve it
379.98306
...........Answer
Answer:
A, D, F
Step-by-step explanation:
AB = 12
BC = 5
AC = 3
To find AC, we can use the pythagoras theorem, square root of 12 power of 2 + 5 power of 2 and we can get 12. Hope this help!
Answer: See each part below.
1) A, B, and C are the coefficients in order when it equals 0. Move over the 4 and you have 5, 9, -4 or Choice B.
3) If you graph the equation, it will be above the x-axis. Therefore, it has no roots. Choice D
4) Choice A is correct. Use the coefficients: A = 4, B = 3, C = -10. Simply plug those into the quadratic equation and you will get -2 and 1.25.
