We need to know about radical form of a number to solve the question. The simplified version of 2[tex]\sqrt{243}[/tex]x is 18[tex]\sqrt{3}[/tex]x.
Radical form of a number is the simplified version of the number where there is no square root or third root or fourth left of the number.If there is a square root of a number present then we have to simplify it and break it down to a square root from where no other natural number root can be found.In this question we have a number 2[tex]\sqrt{243}[/tex]x, we have to simplify [tex]\sqrt{243}[/tex] so we get the radical form of the number and we assume that x>=0. We can write 243 as 9x9x3, so we can see that for the square root of 243 we can write 9[tex]\sqrt{3}[/tex]. So the number 2[tex]\sqrt{243}[/tex]x can be written as 2x9[tex]\sqrt{3}[/tex]x=18[tex]\sqrt{3}[/tex]x.
Therefore we got the radical form of 2[tex]\sqrt{243}[/tex]x to be 18[tex]\sqrt{3}[/tex]x.

graph y=16-8x. .............
Answer: graph 'y=16-8x'
Step-by-step explanation:
First, alter the equation by making it a 'y=...' statement (y=-8x+16).
Secondly, plot your first point at positive 16.
Third, make sure that your slope is going down 8 from positive 16, so you plot your second point at positive 8, and move that second point to the right by 1.

A ball is thrown from a height of 205 feet with an initial downward velocity of 11 ft/s. The ball's height h (in feet) after 1 seconds is given by the following.
h=205-111-161²
How long after the ball is thrown does it hit the ground?
By free fall motion, the ball will take a time of 3.252 seconds to hit the ground.
How much time does a ball take to hit the ground?
The ball experiments a free fall motion, that is an uniform accelerated motion due to gravity, in which effects from Earth's rotation and air viscosity are neglected. The height of the ball (h), in feet, is modelled by a quadratic equation:
h = 205 - 11 · t - 16 · t²
Where t is the time, in seconds.
If we know that h = 0 ft, then the time needed for the ball to hit the ground is:
205 - 11 · t - 16 · t² = 0
16 · t² + 11 · t - 205 = 0
16 · [t² + (11 / 16) · t - 205 / 16] = 0
16 · (t - 3.252) · (t + 3.940) = 0
For time is a whole number, only the first root offers a reasonable answer.

A pump can dispose of sludge at the rate of 6,000 lb/h. How many pounds can be disposed of per minute?
Amount of sludge dispose per minutes is 100 lb.
What is Rate of change?
A rate is anything that can be measured over time. Common rates include velocity (which is the rate of distance traveled), power (rate of work being done), etc. All these have one thing in common which is that they are all divided by the amount of time it took to obtain a certain measurement.
Here it is given that :
A pump can dispose of sludge at the rate of 6,000 lb/h, that is in one hour pump dispose 6000 lb of sludge.
it is known that 1 hour = 60 minutes
Therefore, to find the amount of sludge dispose by pump in ome minute we divide 6000 with 60 :
amount of sludge dispose in one hour = 6000 lb
amount of sludge dispose in 60 minutes = 6000 lb
amount of sludge dispose in 1 minutes = 6000 lb/60 = 100 lb
Therefore, amount of sludge dispose per minutes is 100 lb

Find the equation of the line using the given information
the slope equals zero and it passes through the point (x,y) = (1, -4)
The equation of line which passes through (1, -4) and whose slope is 0 is y = -4.
According to the given question.
A line passes throught the point (1, -4) and its slope is 0.
Let the equation of the line be y = mx + b.
Where,
m is the slope of the line
and b is the y intercept.
Since, the line is passing through (1, -4) and slope is 0 i.e. m = 0.
Therefore, m = 0 and (x, y) = (1, -4) must statisfy y = mx + b.
-4 = 1(0) + b
⇒ -4 = b
⇒ b = -4
Therefore, the equation of line which passes through (1, -4) and whose slope is 0 is y = -4.

No. of years principal is invested = 4 years
Calculating the amount in the bank account after 4 years, using the formula:
Simple interest = P*R*T/100
where P = principal invested
R = rate of interest annually
T = number of years amount is invested
So, Simple interest on the principal invested for 4 years= 6000*2.25*4/100 = 540

Find the slope-intercept form of the line that is perpendicular to −2x+6y=−1 and passes through the point (−2,4)
The equation of line that is perpendicular to the given equation and passes through the given point is y = -3x - 2.
Given the equation of line and point;
−2x + 6y = −1(-2,4)First, find the slope intercept form ( y = mx + b )of the given equation to determine the slope.
−2x + 6y = −1
Solve for y
6y = 2x - 1
y = (2/6)x - 1/6
y = (1/3)x - 1/6
Hence, the slope m = 1/3
Now, the equation of a perpendicular line must have a slope that is the negative reciprocal of the original slope.
Slope of the perpendicular will be;
m_perpendicular = -3
Next, find the equation of the perpendicular line using the point slope formula y - y₁ = m( x - x₁ ).
Plug in the slope m = -3 and the point (-2,4).
y - y₁ = m( x - x₁ )
y - 4 = -3( x - (-2) )
y - 4 = -3( x + 2 )
y - 4 = -3x - 6
y = -3x - 6 + 4
y = -3x - 2
Therefore, the equation of line that is perpendicular to the given equation and passes through the given point is y = -3x - 2.

2. Write an algebraic inequality model that represents this situation.
3. Show all work to solve the inequality.
4. Graph the inequality.
5. Describe the possible numbers of times you can play the same video game.
Answer:
3
Step-by-step explanation:
and the answer is 17
Answer:
1. The total cost of movie and the total cost of refreshments purchased and the total cost of video games played cannot exceed 40
2. 14.50 + 7.75x + 0.75y ≤ 40
3. y ≤ 34 - 10.333x
4. See attached graph
5.
one refreshment means you can play 23 times
two refreshments means you can play 13 times
three refreshments means you can play 3 times
Step-by-step explanation
We have to assume that you can see one movie but but buy multiple refreshments and play multiple video games. A refreshment is considered to be one drink and one popcorn.
If not we have a situation where we have three unknowns and it will be difficult to solve in a 2D context
1. Verbal inequality model
The total cost of one movie and the total cost of refreshments purchased and the total cost of video games played cannot exceed 40
2. Algebraic Inequality Model
Since the cost of a movie is 14.50 and you are seeing only 1 movie, the cost is 14.50(1) = 14.50
Assume you are going to buy x refreshments. Total cost of refreshments = 7.75x
Assume you are going to play y video games. Total cost of video games played = 0.75y
This cannot be greater than 40 i.e ≤ 40
So the algebraic inequality is
14.50 + 7.75x + 0.75y ≤ 40
3. Solving the inequality
Subtracting 14.50 from both sides we get
7.75x + 0.75y ≤ 25.50
Subtracting 14.50 from both sides we get
7.75x + 0.75y ≤ 25.50
Subtract 7.75x from both sides:
0.75y ≤ 25.50- 7.75x
Divide both sides by 0.75
y ≤ 25.50/0.75 - 7.75x/0.75
which is
y ≤ 34 - 10.333x
3. Graph of Inequality
This is an inequality in 2 variables and can be graphed.
See attached graph. The shaded portion represents the inequality
y ≤ 34 - 10.333x
Note that since neither x nor y can be < 0, we should not consider any portion of the shaded area which would mean two more constraints x ≥ 0 and y ≥ 0 but in this case I have stuck to only the above one inequality
5. Possible number of times you can play the same video game
Again we consider only 1 movie and multiple refreshments and video games
Using the inequality y ≤ 34 - 10.33x
If x = 1 refreshment,
y ≤ 34 - 10.33 x 1
y ≤ 23.67 or max 23 times you can play the video game max
If x = 2,
y ≤ 34 - 10.33 x 2
y ≤ 13.34 or maximum 13 times
If x = 3
y ≤ 34 - 30.99
y ≤ 3.01 or maximum 3 times

The intercepts of the graph (0, 6) (0, -6) is symmetry on x-axis, y-axis and it is graphically shown.
What is a symmetry of a function?A symmetry of a function is a transformation that leaves the graph unchanged. Symmetric function is a function having several variables which remain unchanged for any type of permutation of the variable.
For the given situation, Symmetry with respect to x-axis
The point becomes (x, -y) as the point flips by itself up or down which changes its y coordinate to negative of whatever it was. And there is no motion is done horizontally so no change in x coordinate.
The interecpets are; (0, 6) (0, -6)
Thus this intercepts is symmetric to y-axis. this intercepts is not symmetric about origin.
Hence we can conclude that the intercepts is symmetric about x - axis.
