The step function and its graph that represents the relationship between the number x of days and the total cost y of renting the chipper are present in the first option.
What is a step function?A function on the real numbers is referred to as a step function in mathematics if it can be expressed as a finite linear combination of interval indicator functions. A step function is, informally speaking, a piecewise constant function with a finite number of pieces.Given:
Charge for 1 day = $100
Charge for each additional day = $50
Let's assume
The cost of rent is y.
The number of days is x.
The total cost, y according to the data provided can be calculated by the equation,
y = 100 + 50x
Using y = mx+c, when graphing a step function that represents the relationship between the number of days and the total cost,
The gradient or slope will be always 50 for the graph.
So, when x = 0, y = 100 + 0 = 100
When x = 1, y = 100 + 50 = 150
When x = 2, y = 100 + 50 × 2 = 200
When x = 3, y = 100 + 50 × 3 = 250
Thus the step function is,
f(x) = 100 , if 0 < x ≤ 1
f(x) = 150 , if 1 < x ≤ 2
f(x) = 200 , if 2 < x ≤ 3
f(x) = 250 , if 3 < x ≤ 4

The value of the limit will be equal to -2.
A function may be defined as the one in which for one input variable x there is only one output variable y. The input variable is called independent variable and the output variable is called dependent variable. Limit on a function may be defined as the value of input variable reaches a certain specified value the output of function also reaches a certain specified value. The function [tex]\lim_{x \to-2}[/tex] (x²)/(2x + 4) can be solved by using the rule [tex]\lim_{x \to a}[/tex] f(x)/g(x) = [tex]\lim_{x \to a}[/tex] f'(x)/g'(x).
Here f(x) = x², f'(x) = 2x
g(x) = 2x + 4, g'(x) = 2

An arch is in the shape of a parabola. It has a span of 72 meters and a maximum height of 9 meters.
Answers
Answer:
Equation of the parabola:
[tex]y=-\frac{1}{144}x^2+9[/tex]The height of the arch 18 meters from the center is 6.75m
Explanation:
The arch feet are 72m apart and the origin half way between them. This means that the axis of symmetry (or the x.coordinate of the vertex) is x = 0
Since it's an arch, the parabola is concave down, with it's maximum at the vertex, y = 9. This means that the vertex is at (0, 9). Also, we can see that the y-intercept is y = 9
Finally, we know the two roots of the parabola: x = -36 and x = 36. This is because the points x = -36 and x = 36 are 72m apart, with the center at the original, as the problem says. SInce x = 36 is a root, this means that at that point the y value is 0.
With all this, we can try to find the general form of a parabola. The general form is:
[tex]y=ax^2+bx+c[/tex]c is the y-intercept. We know that c = 9
We can find the value of b, because we know the coordinates of the vertex. The x-coordinate of the vertex is:
[tex]x_{vertex}=-\frac{b}{2a}[/tex]SInce the x-coordinate of the vertex is x = 0
[tex]0=-\frac{b}{2a}[/tex]If we solve:
[tex]b=0[/tex]So far we have:
[tex]y=ax^2+9[/tex]Finally, to find a, we can use the point (36, 0) (one of the roots)
[tex]0=a(36)^2+9[/tex]And solve:
[tex]\begin{gathered} 324a=-9 \\ . \\ a=-\frac{9}{1296}=-\frac{1}{144} \end{gathered}[/tex]Thus, the equation of the arch is:
[tex]y=-\frac{1}{144}x^2+9[/tex]Evaluating this equation for x = 18, we can find the height of the arch:
[tex]y=-\frac{1}{144}(18)^2+9=-\frac{9}{4}+9=-6.75[/tex]The entire graph of the function f is shown in the figure below.

A(-3,-2) and M (2,6) find the coordinates of the other endpoint
Answers
The other endpoint of the segment is (7, 14)
How to determine the coordinate of the other endpoint?From the question, we have:
On the segment, we have the following endpoints
Endpoint 1, A = (-3,-2)
Midpoint, M = (2,6)
The midpoint of the segment is calculated using
Midpoint (x, y) = 1/2 * (x1 + x2, y1 + y2)
Where
(x1, y1) = (-3,-2)
(x, y) = (2,6)
Substitute the known values in the above equation
So, we have
(2, 6) = 1/2 * (-3 + x, -2 + y)
Multiply both sides of the equation by 2
So, we have
(4, 12) = (-3 + x, -2 + y)
By comparison, we have
-3 + x = 4
-2 + y = 12
Evaluate the like terms in the above equation
So, we have
x = 7
y = 14
When the above solution is represented as a coordinate, we have the following
(x, y) = (7, 14)
Hence, the other endpoint of the segment where the segment has the endpoint (-3,-2) and midpoint (2,6) is (7, 14)

Step-by-step explanation:
To find k, we use
∫∞−∞∫∞−∞fXY(x,y)dxdy=1.
Thus, we have
1=∫∞−∞∫∞−∞fXY(x,y)dxdy=∫10∫10x+cy2dxdy=∫10[12x2+cy2x]x=1x=0dy=∫1012+cy2dy=[12y+13cy3]y=1y=0=12+13c.
Therefore, we obtain c=32.
To find P(0≤X≤12,0≤Y≤12), we can write
P((X,Y)∈A)=∬AfXY(x,y)dxdy,for A={(x,y)|0≤x,y≤1}.
Thus,
P(0≤X≤12,0≤Y≤12)=∫120∫120(x+32y2)dxdy=∫120[12x2+32y2x]120dy=∫120(18+34y2)dy=332.
We can find marginal PDFs of X and Y from their joint PDF. This is exactly analogous to what we saw in the discrete case. In particular, by integrating over all y's, we obtain fX(x). We have
Marginal PDFs
fX(x)=∫∞−∞fXY(x,y)dy, for all x,fY(y)=∫∞−∞fXY(x,y)dx, for all y.

Find the equation of the line that is perpendicular to this line and passes through the point (8,4).
Find the equation of the line that is parallel to this line and passes through the point (8,4)..
Answers
Considering the definition of parallel and perpendicular line, you get:
the equation of the line that is perpendicular to this line and passes through the point (8,4) is y= -8/5x + 84/5.the equation of the line that is parallel to this line and passes through the point (8,4) is y=5/8 -1.Linear equationA linear equation o line can be expressed in the form y = mx + b
where
x and y are coordinates of a point.m is the slope.b is the ordinate to the origin and represents the coordinate of the point where the line crosses the y axis.Parallel lineParallel lines are two lines that are always at the same distance from each other.
Two lines are parallel if they have the same slope and different y-intercepts.
Perpendicular linePerpendicular lines are lines that intersect at right angles or 90° angles. If you multiply the slopes of two perpendicular lines, you get –1.
Equation of perpendicular line in this caseThe line is y= 5/8x -4, with a value of slope m of 5/8 and ordinate to the origin b of -4.
If you multiply the slopes of two perpendicular lines, you get –1, the slope perpendicular line can be calculated as:
5/8× slope perpendicular line= -1
slope perpendicular line= (-1)÷ 5/8
slope perpendicular line= -8/5
So, the perpendicular line has a form of: y= -8/5x + b
The line passes through the point (8, 4). Replacing in the expression for perpendicular line:
4= -8/5×8 + b
4= -64/5 + b
4 + 64/5= b
84/5= b
Finally, the equation of perpendicular line is y= -8/5x + 84/5.
Equation of parallel line in this caseIn this case, the line is y= 5/8x -4, with a value of slope m of 5/8 and ordinate to the origin b of -4.
If two lines are parallel if they have the same slope, the parallel line has a slope of 5/8 and has a form of: y= 5/8x + b
The line passes through the point (8, 4). Replacing in the expression for parallel line:
4= 5/8×8 + b
4= 5 + b
4 -5 = b
-1 = b
Finally, the equation of parallel line is y= 5/8x - 1

Paint needed for outside = x + 19
So,
Total paint = Paint for outside + Paint for inside
107 = x + x+ 19
107 = 2x + 19
2x = 88
x = 44

Step-by-step explanation:
y varies directly as x. y = 90 when x = 6. Find y when x= 12.y=(Simplify your answer.)
Answers
Answer
When x = 12, y = 180
Explanation
We are told that y varies directly as x, which can be written as
y ∝ x
Introducing the constant of variation, k, we have
y ∝ x
y = kx
We can then solve for k knowing that
y = 90 when x = 6
y = kx
90 = (k) (6)
90 = 6k
Divide both sides by 6
(90/6) = (6k/6)
15 = k
k = 15
We can then write the relationship between y and x as
y = kx
y = 15x
when x = 12, y = ?
y = 15x
y = 15 (12) = 180

Suppose times for the 100m sprint for the average person are Uniondale and symmetric with mean 14 seconds and standard deviation 0.8 seconds. What is the probability that the average person has a time faster than Usain Bolt’s record of 9.58 seconds?
Answers
The probability that the average person has a time faster than Usain Bolt’s record of 9.58 seconds
P(x>9.58)=1
This is further explained below.
What is the probability?Mean[tex](\mu)[/tex]=14 seconds
Standard deviation[tex](\sigma)[/tex]=0.8 seconds
To determine the likelihood that the average individual will beat Usain Bolt's record of 9.58
To express the statement "the probability that the average person has a time faster than Usain Bolt’s record of 9.58 seconds" in a mathematical equation we have:
[tex]&P(x > 9.58)=P\left(\frac{x-\mu}{\sigma} > \frac{9.58-14}{0.8}\right) \\\\&P(x > 9.58)=P\left(z > -\frac{4.42}{0.8}\right) \\\\ &P(x > 9.58)=P(z > -5.525)[/tex]
P(x>9.58)=1
Note: we would make use of the normal table in reading z>-5.525
In conclusion, By using standard normal distribution we get
P(x>9.58)=1
