y =5.5x represents a proportional relationship. What is the constant proportionality?
Answer: 5.5 is the constant proportionality.
Step-by-step explanation:
Since we have given that
y = 5.5x
As we can see that
y is directly proportional to x.
So, mathematically written as
[tex]y\ \alpha\ x\\\\y=kx[/tex]
If we comparing both the expression, we get that
k = 5.5.
Hence, 5.5 is the constant proportionality.
The constant of proportionality of y = 5.5x is 5.5.
A directly proportional relational relationship can be represented below
y ∝ xwhere
∝ = symbol for proportionality
y and x are the variable that are related. Therefore,
y = kx
where
k = constant of proportionality.
The equations y = 5.5x can be modelled as directly proportional relationship using y = kx.
Therefore, k = 5.5 is the constant of proportionality.
The constant of proportionality of y = 5.5x is 5.5.

Ari has a total of 22 coins consisting of pennies and nickels. The total value of the coins is $0.54.
How many of each type of coin does Ari have?
Answer:
Let n = the number of nickels that Ari has.
Let p = the number of pennies that Ari has.
The total number of coins she has is 22.
n + p = 22
We have our first equation... But we another one to solve this.
Each penny is going to be $0.01 and a nickel is work $0.05.
And the total is $0.54
Our second equation. 0.05n + 0.01p = 0.54
n + p = 22
0.05n + 0.01p = 0.54
Multiply the top by -0.05
-0.05n - 0.05p = -1.1
0.05n + 0.01p = 0.54
The n terms cancel out.
-0.04p = -0.56
p = 14

Find the values of x and y that satisfy the equation. 3x+6i=27+yi
The values that satisfy the equation 3x + 6i = 27 + yi are x = 9 and y = 6, which are found by equating real and imaginary parts separately.
To find the values of x and y that satisfy the equation 3x + 6i = 27 + yi, we must equate the real parts and the imaginary parts separately. The real part of the equation gives us x, and the imaginary part gives us y.
From the real part, we have:
3x = 27
x = 27 / 3
x = 9
From the imaginary part, we have:
6i = yi
y = 6
Therefore, the values x = 9 and y = 6 satisfy the given equation.

b.
4.35x10^7 aluminum cans
c.
1.09x10^8 aluminum cans
d.
1.63x10^8 aluminum can
Answer:
the answer is A
Step-by-step explanation:
Final answer:
The answer is approximately 2.61x10⁹ cans recycled in 16 days, which is option (a).
Explanation:
The student is asking about a mathematical estimation of how many aluminum cans are recycled over a 16-day period, given an average rate of recycling per minute.
To find the answer, we'll first calculate the number of minutes in 16 days:
16 days × 24 hours/day × 60 minutes/hour = 23,040 minutes.
Now, we multiply this by the average number of cans recycled per minute:
23,040 minutes × 113,204 cans/minute = 2.61x10⁹ cans.
Expressing this value in scientific notation gives us:
About 2.61x10⁹ aluminum cans recycled in 16 days, which corresponds to option (a) in the multiple-choice provided by the student.

The amount of milk sold each day by a grocery store varies according to the Normal distribution with mean 130 gallons and standard deviation 12 gallons. On a randomly selected day, the probability that the store sells at least 154 gallons is
A. .0228.
B. .1587.
C. .8413.
D. .9772.
To find the probability that the store sells at least 154 gallons of milk on a randomly selected day, we need to standardize the value and use a standard normal distribution table or calculator.
Explanation:To find the probability that the store sells at least 154 gallons of milk on a randomly selected day, we need to find the area under the Normal distribution curve to the right of 154.
First, we need to standardize the value of 154 using the formula Z = (X - mean) / standard deviation, where X is the value we want to standardize, mean is the mean of the distribution, and standard deviation is the standard deviation of the distribution. Using the given values, we have Z = (154 - 130) / 12 = 2.
Next, we can use a standard normal distribution table or a calculator to find the cumulative probability associated with a z-score of 2. The probability that a standard normal random variable is greater than 2 is approximately 0.0228.
Therefore, the probability that the store sells at least 154 gallons of milk on a randomly selected day is approximately 0.0228, or option A.
What transformations change the graph of (f)x to the graph of g(x)?
f(x) = x² ; g(x) = (x + 7)² + 9
The graph of g(x) is obtained by the combination of shifting the graph of f(x) to the left 7 units and upward 9 units.
Further explanationTransformation of a graph: changing the shape and location of a graph.
We already know there are four types of transformation geometry: translation (or shifting), reflection, rotation, and dilation (or stretching).
The transformation that we will discuss is shifting horizontally or vertically.Translation (or shifting): moving a graph on an analytic plane without changing its shape.Vertical shift: moving a graph upwards or downwards without changing its shape.Horizontal shift: moving a graph to the left or right downwards without changing its shape.In general, given the graph of y = f(x) and k > 0, we obtain the graph of:
[tex]\boxed{ \ y = f(x) + k \ }[/tex] by shifting the graph of [tex]\boxed{ \ y = f(x) \ }[/tex] upward k units.[tex]\boxed{ \ y = f(x) - k \ }[/tex] by shifting the graph of [tex]\boxed{ \ y = f(x) \ }[/tex] downward k units.Furthermore in general, given the graph of y = f(x) and h > 0, we obtain the graph of:
[tex]\boxed{ \ y = f(x + h) \ }[/tex] by shifting the graph of [tex]\boxed{ \ y = f(x) \ }[/tex] to the left h units.[tex]\boxed{ \ y = f(x - h) \ }[/tex] by shifting the graph of [tex]\boxed{ \ y = f(x) \ }[/tex] to the right h units.,The combination of vertical and horizontal shifts is as follows:
[tex]\boxed{\boxed{ \ y = f(x \pm h) \pm k \ }}[/tex]
The plus or minus sign follows the direction of the shift, i.e., up-down or left-right
Given: [tex]\boxed{ \ f(x) = x^2 \ becomes \ g(x) = (x + 7)^2 + 9 \ }[/tex]
We set h = +7 and k = +9.
In the graph, additionally note the shift of points from (0, 0) to (-7, 9).
Conclusion
The graph of g(x) is drawn by the combination of shifting the graph of f(x) to the left 7 units and upward 9 units.

The graph of the function [tex]g(x)=(x+7)^{2}+9[/tex] is obtained from the graph of the function [tex]f(x)=x^{2}[/tex] when each point on the curve of [tex]f(x)=x^{2}[/tex] is shifted [tex]7[/tex] units towards the negative direction of [tex]x-[/tex] axis and then shifted [tex]9[/tex] units towards the positive direction of [tex]y-[/tex] axis.
Further explanation:
The functions are given as follows:
[tex]\fbox{\begin\\\ \begin{aligned}f(x)&=x^{2}\\g(x)&=(x+7)^{2}+9\end{aligned}\\\end{minispace}}[/tex]
The objective is to determine the transformation or the way in which the graph of the function [tex]g(x)[/tex] is obtained from the graph of the function [tex]f(x)[/tex].
Concept used:
Shifting of graphs:
Shifting is a rigid translation because it does not change the size and shape of the curve. Shifting is used to move the curve vertically or horizontally without any change in shape and size of the curve.
The function [tex]y=f(x+a)[/tex] and [tex]y=f(x-a)[/tex] is a shift of the curve [tex]y=f(x)[/tex] horizontally towards negative and positive direction of [tex]x-[/tex]axis respectively.
The function [tex]y=f(x)+a[/tex] and [tex]y=f(x)-a[/tex] is a shift of the curve [tex]y=f(x)[/tex] vertically towards positive and negative direction of [tex]y-[/tex]axis respectively.
Step1: Draw the graph of the function [tex]f(x)=x^{2}[/tex].
Figure 1 (attached in the end) represents the graph of the function [tex]f(x)=x^{2}[/tex]. From figure 1 it is observed that the curve of the function [tex]f(x)=x^{2}[/tex] is a parabola with origin as the vertex and mounted upwards.
Step 2: Obtain the graph of the function [tex]g'(x)=(x+7)^{2}[/tex] from the graph of the function [tex]f(x)=x2[/tex].
The function [tex]g'(x)=(x+7)^{2}[/tex] is of the form [tex]y=f(x+a)[/tex].
So, as per the concept of shifting of the graphs the graph of the function [tex]g'(x)=(x+7)^{2}[/tex] is obtained from the graph of the function [tex]f(x)=x^{2}[/tex] when each point on the curve of [tex]f(x)=x^{2}[/tex] is shifted [tex]7[/tex] units towards the negative direction of [tex]x-[/tex]axis.
Figure 2 (attached in the end) represents the graph of the function [tex]g'(x)=(x+7)^{2}[/tex].
In figure 2 the dotted line represents the curve of [tex]f(x)=x^{2}[/tex] and the bold line represents the curve of [tex]g'(x)=(x+7)^{2}[/tex].
Step3: Obtain the graph of the function [tex]g(x)=(x+7)^{2}+9[/tex] from the graph of the function [tex]g'(x)=(x+7)^{2}[/tex].
The function [tex]g(x)=(x+7)^{2}+9[/tex] is of the form [tex]y=f(x)+a[/tex].
So, as per the concept of shifting of graph the graph of the function [tex]g(x)=(x+7)^{2}+9[/tex] is obtained from the graph of the function [tex]g'(x)=(x+7)^{2}[/tex] when each point on the curve of [tex]g'(x)=(x+7)^{2}[/tex] is shifted [tex]9[/tex] units towards upwards or the positive direction of [tex]y-[/tex]axis.
Figure 3 (attached in the end) represents the graph of the function [tex]g(x)=(x+7)^{2}+9[/tex].
In figure 3 the dotted line represents the curve of [tex]g'(x)=(x+7)^{2}[/tex] and the bold line represents the curve of [tex]g(x)=(x+7)^{2}+9[/tex].
From the above explanation it is concluded that the graph of the function [tex]g(x)=(x+7)^{2}+9[/tex] is obtained from the graph of the function [tex]f(x)=x^{2}[/tex] when each point on the curve of [tex]f(x)=x^{2}[/tex] is shifted [tex]7[/tex] units towards the negative direction of [tex]x-[/tex] axis and then shifted [tex]9[/tex] units towards the positive direction of [tex]y-[/tex] axis.

the graph of a line goes up and to the right when:
a) the coefficent of x is 0
b) the coffecient of x is negative
c) the coffecient of x is positive
d) there is no coffecient of x
Option: C is the correct answer.
c) the coefficient of x is positive
Step-by-step explanation:We know that graph of a line goes up and to the right when the coefficient of x is positive.
Since we know that when a line goes up and to the right this means that the line is increasing and hence we will get a positive slope of the line and we know that the slope intercept of a line is given as:
[tex]y=mx+c[/tex]
as m is positive this means that:
the coefficient of x is positive.
Hence, the correct answer is:
c) the coefficient of x is positive
The graph of a line goes up and to the right when the coefficient of x is positive, indicating it has an upward slope. This occurs when 'b' in the equation 'y = a + bx' is greater than zero.
The graph of a line wil go up and to the right when the coefficient of x is positive. In other words, when we have an equation like y = a + bx and b is greater than zero, the line has an upward slope. This means that for each step we move to the right on the x-axis, the value of y increases. Therefore, the correct answer to the question is (c) the coefficient of x is positive.
As a reference:
When the slope coefficient b is zero (b = 0), the line is horizontal.If b is negative (b < 0), the line slopes downward to the right.An increase in the slope will cause the line to rotate counter-clockwise around the y-intercept, indicating an increase in its steepness if the slope was positive or a decrease in its negativity if the slope was negative.Remember, the term positive slope indicates the line rises as it moves from left to right, while a negative slope indicates a line that falls as it moves from left to right.
