Answers
Evaluate the logarithmic functions provided at different values of x to see which matches better the data from the y column:
1) f(x)= 60.04 - 8.25 * ln(x)
[tex]\begin{gathered} f(1)=60.04-8.25\ln (1) \\ =60.04 \\ \\ f(2)=60.04-8.25\ln (2) \\ =54.32\ldots \\ \\ f(3)=60.04-8.25\ln (3) \\ =50.97\ldots \\ \\ f(4)=60.04-8.25\ln (4) \\ =48.60 \\ \\ f(5)=60.04-8.25\ln (5) \\ =46.76 \\ \\ f(6)=60.04-8.25\ln (6) \\ =45.26\ldots \\ \\ f(7)=60.04-8.25\ln (7) \\ =43.98\ldots \end{gathered}[/tex]2) f(x) = 8.25 - 60.04 * ln(x)
[tex]\begin{gathered} f(1)=8.25-60.04\ln (1) \\ =8.25 \\ \\ f(2)=8.25-60.04\ln (2) \\ =-33.36\ldots \\ \\ f(3)=8.25-60.04\ln (3) \\ =-57.71\ldots \\ \\ f(4)=8.25-60.04\ln (4) \\ =-74.98\ldots \\ \\ f(5)=8.25-60.04\ln (5) \\ =-88.38\ldots \\ \\ f(6)=8.25-60.04\ln (6) \\ =-99.32\ldots \\ \\ f(7)=8.25-60.04\ln (7) \\ =-108.58\ldots \end{gathered}[/tex]The rest of the given functions are not logarithmic.
We can see from the computed values for the given logarithmic functions, that the one which best fits the data, is: f(x)=60.04-8.25*ln(x).

Solution
The equation of a line passing through two different points is given as
[tex]\begin{gathered} Point1:(x_1,y_1) \\ Point2:(x_2,y_2) \\ \frac{y-y_1}{x-x_1}=\frac{y_2-y_1}{x_2-x_1} \end{gathered}[/tex]Substitte the given coordinates of the points given into the formula

[tex]Ax+By=C[/tex]But since the x-coordinates of the points are equal, then the formula for slope is not applicable (the denominator equals 0).
In this case, we say that the slope is undefined (the line is vertical).
This means that the equation of the line doesn't contain y.
Thus, the equation of the line is x=10.
Answer: the slope is undefined.
The equation of the line is x = 10.

Answers
Answer:
200
Explanation:
To know the total number of graders, we will use the rule of three. Where we know that 40% is equivalent to 80 graders and we want to know how many graders are equivalent to 100%. Then:
40% -------- 80 seventh graders
100% -------- x
Where x is the number of seventh graders in the class.
So, solving for x, we get:
[tex]x=\frac{100\text{ \% }\cdot\text{ 80}}{40\text{ \%}}=200\text{ seventh graders}[/tex]Then, there are 200 seventh graders in the class.

Answers
GIVEN:
We are told that a real estate agent believes that most of the home prices are low with very few homes having very high prices in a certain area.
Required;
If his description is accurate, which shape best describes the distribution of home prices in this area?
Explanation;
For data distribution, the graph can take on different shapes dpending on how the data is distributed. In this particular instance, most of the data is lying on the left side of the graph. In other words, the curve is more elevated on the left side while its very low towards the right side.
The following picture is an illustration of this scenario;
This is "Positively skewed data distribution."
ANSWER:
Positively skewed.
Consider the equation. y=1/4(x-5)^2-3Vertex (5,-3)The next step in graphing a parabola is to find points that will determine the shape of the curve. Find the point on the graph of this parabola that has the X-coordinates X=3.
Answers
We have the equation:
[tex]y=\frac{1}{4}(x-5)^2-3[/tex]This is a parabola expressed in vertex form, where the vertex is (h,k) = (5,-3).
We have to graph the parabola. To do that we need another point, as we already know the vertex and, therefore, the axis of symmetry (x = 5).
We can find another point by giving a value to x and calculating y.
For example, with x = 3 we get:
[tex]\begin{gathered} y(3)=\frac{1}{4}(3-5)^2-3 \\ y(3)=\frac{1}{4}(-2)^2-3 \\ y(3)=\frac{1}{4}\cdot4-3 \\ y(3)=1-3 \\ y(3)=-2 \end{gathered}[/tex]The point that belongs to the parabola when x = 3 is (3, -2).
Then, we can graph the two points and draw the parabola as:
Because of the symmetry at x = 5, we also know that two units to the right, at x = 7, we will have the same value of y that we have for x = 3.
With at least 3 points, we can graph a parabola.
The actual graph is:
If we want to add more precision to our graph, we can calculate more points that belong to the parabola.
For example, at the other side of the vertex, we can calculate the value of y for x = 6:
[tex]\begin{gathered} y(6)=\frac{1}{4}(6-5)^2-3 \\ y(6)=\frac{1}{4}(1)^2-3^{} \\ y(6)=\frac{1}{4}-3 \\ y(6)=\frac{1}{4}-\frac{12}{4}^{} \\ y(6)=-\frac{11}{4}=-2.75 \end{gathered}[/tex]We can add this to the plot as:
We have to aproximate the position of y as the grid only shows integers and y = -2.75.
Answer:
The points in the parabola are (5,-3), (3,-2) and (6,-2.75). We need at least 3 points to plot a parabola.

Answers
Let x represent the amount invested at 7%.
Then 9000-x is the amount invested at 4%
total interest earned is:
0.07x + 0.04(9000-x) = 510
0.07x + 360 - 0.04x = 510

Given,
The Hudson family is saving for a family vacation to Disney World. They determine that the trip will cost $3,200. Mr. and Mrs. Hudson have already set aside $1,500 for the trip.
Here we need to find the amount they need to save for each week if they leave in 16 weeks.
While we looking into the given question,
Total amount of Saving = $3,200.
Amount in hand = $1,500
So, the amount need is calculated as,
=> 3200 - 1500
=> 1700
Here we have the 16 week time,
So, the saving for each week is calculated as,
=> 1700/16
=> 106.25
Therefore, the family have to save $106.25 for each week.

The range of the function g(x) = x² + 2 for the given domain is found to be {27,3,25,6,102}.
What is the difference between domain and range in function?The domain of a function is the set of values that may be plugged into it. This set contains the x values in a function like f. (x). A function's range is the set of values that the function can take. This is the collection of values that the function returns when we enter an x value.
How do you find domain and range in the absence of numbers?To determine the domain of a function, f(x), determine which values of x cause f(x) to be undefined/not real. The usual procedure for determining range is to find x in terms of f(x) and then locate values of f(x) for which x is not defined.
Given:
g(x) = x² + 2
Domain of the function: {-5, -1, 0, 2, 10}
We need to find the range.
Let us substitute x = -5 in g(x)
g(-5) = (-5)² + 2
= 27
g(-1) = (-1)² + 2
= 3
g(0) = (0)² +(-5)²
= 25
g(2) = (2)² + 2
=6
g(10) = (10)² + 2
= 102
Therefore, the range of the given function g(x) = x² + 2 for a given domain is found to be {27,3,25,6,102}.

The equation will be:
[tex]150\times x\%=60[/tex]Now,
We need to solve the above equation for the value of x.
Then,
Divide by 150 on both sides of the equation:
[tex]\frac{150}{150}\times x\operatorname{\%}=\frac{60}{150}[/tex]Then,
[tex]\begin{gathered} x\%=\frac{60}{150} \\ x\operatorname{\%}=\frac{6}{15} \\ x\operatorname{\%}=0.4 \\ x=0.4\times100 \\ x=40 \end{gathered}[/tex]Final answer:
Hence, the percentage is 40%.
Hello can you assist me with number 11Find the midpoint
Answers
Answer:
(-3, 2.5)
Explanation:
The midpoint of two points of coordinates (x1, y1) and (x2, y2) has the following coordinates
[tex](\frac{x_1+x_2}{2},\frac{y_1+y_2}{2}_{})[/tex]Then, the midpoint can be calculated replacing (x1, y1) = (3, 3) and (x2, y2) = (-9, 2), so
[tex](\frac{3+(-9)}{2},\frac{3+2}{2})=(\frac{-6}{2},\frac{5}{2})=(-3,2.5)[/tex]Therefore, the midpoint is (-3, 2.5)
