Prove or disprove each of these statements about the floor and ceiling functions. a) ⌊⌈x⌉⌋ = ⌈x⌉ for all real numbers x. b) ⌊x+y⌋=⌊x⌋+⌊y⌋for all real numbers x and y. c) ⌈⌈x∕2⌉ ∕2⌉ = ⌈x∕4⌉ for all real numbers x. d)⌊√⌈x⌉⌋ = ⌊√x ⌋ for all positive real numbers x. e) ⌊x⌋+⌊y⌋+⌊x+y⌋≤⌊2x⌋+⌊2y⌋forall real numbers x and y.
Answer:
A) equality function will hold
B) equality function doesn't hold
C) equality function holds )
D) equality function doesn't hold
E) equality function holds
Step-by-step explanation:
a) ⌊⌈x⌉⌋ = ⌈x⌉ for all real numbers x.
The ceiling function will yield an integer, that is greater ≥ x.
Also the floor function when applied to an integer will yield the same integer value. hence the two sides will become the same Therefore the equality function will hold
b) ⌊x+y⌋=⌊x⌋+⌊y⌋ for all real numbers x and y
The floor function of this statement yields a value that is ≤ inserted value and this makes the right hand side of the statement to be 1 less than the sum produced from the left hand side of the statement, therefore the equality function doesn't hold
c) ⌈⌈x∕2⌉ ∕2⌉ = ⌈x∕4⌉ for all real numbers x.
The ceiling function produces an integer that is ≥ value inserted and the integer gotten is divided by 2 and this serves a s an input to the ceiling function( which means X has been divide by 4 ) making the two sides of the equation the same ( equality function holds )
d)⌊√⌈x⌉⌋ = ⌊√x ⌋ for all positive real numbers x
The ceiling function is applied to the value inserted in x(on the left hand side ), and the result will not be equal to that in the right hand side.
Therefore the equality function doesn't hold
e) ⌊x⌋+⌊y⌋+⌊x+y⌋≤⌊2x⌋+⌊2y⌋forall real numbers x and y.
If the value of the fractional part of x or y is > 0.5, then the right hand side will be greater than the left hand side by 1.
Otherwise, both left and right hand sides yield equal answers. therefore equality function holds

State if the two triangles are congruent. If they are, state how you know.
Explanation:
AAS = angle angle side
The arc markings show us which pairs of angles are congruent. The pair of congruent sides are the shared overlapping sides. Notice that the sides are not between the red angles, so we go for AAS instead of ASA. The order is important.
We cannot use SAS because we only know info about one pair of congruent sides (not two).

A train is traveling at a speed of 80 km/h when the conductor applies the brakes. The train slows with a constant acceleration of magnitude .5 m/s^2. We want to find the distance the train travels from the time the brakes are applied until the train comes to a complete stop. Which kinematic formula would be most useful to solve for the target unknown?
Answer:
The train will travel 493.817 meters until it stops completely.
Step-by-step explanation:
In this case, we know that train applies the brakes and decelerates at constant rate until rest is reached after travelling an unknown distance. Travelled distance ([tex]\Delta s[/tex]), measured in meters, can be found by using this kinematic formula:
[tex]v^{2} = v_{o}^{2}+2\cdot a \cdot \Delta s[/tex] (Eq. 1)
Where:
[tex]v_{o}[/tex] - Initial speed, measured in meters per second.
[tex]v[/tex] - Final speed, measured in meters per second.
[tex]a[/tex] - Acceleration, measured in meters per square second.
Now travelled distance is cleared within the formula:
[tex]\Delta s = \frac{v^{2}-v_{o}^{2}}{2\cdot a}[/tex]
If we know that [tex]v_{o} = 22.222\,\frac{m}{s}[/tex], [tex]v = 0\,\frac{m}{s}[/tex] and [tex]a = -0.5\,\frac{m}{s^{2}}[/tex], then the distance travelled by the train is:
[tex]\Delta s = \frac{\left(0\,\frac{m}{s} \right)^{2}-\left(22.222\,\frac{m}{s} \right)^{2}}{2\cdot \left(-0.5\,\frac{m}{s^{2}}\right) }[/tex]
[tex]\Delta s = 493.817\,m[/tex]
The train will travel 493.817 meters until it stops completely.

The kinetic energy k of an object in joules is given by the formula k=1/2mv² where m is the object's mass in kilograms and v is its velocity in meters per second. An object’s velocity is 20 meters per second, and its kinetic energy is 48,000 joules. If it speeds up to 40 meters per second, what is its new kinetic energy?
Answer:
192000 J
Step-by-step explanation:
k = 1/2 mv²
48000 = 1/2 x m x (20)²
48000 = 200m
m = 240 kg
new k
k = 1/2 x 240 x 40²
k = 192000 J
