Answer:
the minimum temperature was furthest from the norm. it was 23.5 degrees further
Step-by-step explanation:
difference between the max and median = 115-98.6 = 16.4
difference between the median and minimum = 98.6 - 58.7 = 39.9
the difference between the median and minimum (39.9) is greater than the distance between the maximum and median (16.4). thus, the minimum temperature was furthest from the norm. the difference in differences is 39.9 - 16.4 = 23.5 degrees. this means that the minimum temperature was 23.5 degrees further away from the norm than the maximum was
Determine the graph that represents a function. On a coordinate plane, a circle is shown that crosses the x-axis at (negative 5, 0), the y-axis at (0, 5), the x-axis at (5, 0), and the y-axis at (0, negative 5). On a coordinate plane, a parabola opens to the left. It crosses the y-axis at (0, 3) and (0, negative 3), and the x-axis at (9, 0). On a coordinate plane, a straight line with a positive slope crosses the y-axis at (0, negative 2) and the x-axis at (1.2, 0).
Answer: The graph that represents a function is the parabola that opens to the left.
This can be determined by the following characteristics of the graph:
It is a parabola because it opens to the left and has a vertex on the y-axis.
It crosses the y-axis at (0, 3) and (0, negative 3), which means that it is symmetric about the y-axis, and also it crosses the x-axis at (9, 0) which means that it is a function.
A circle is not a function because, for any value of x, there are two different values of y that can be plotted on the graph (i.e. the point (5,0) and (-5,0) produce two different y values)
A straight line with a positive slope is not a function because, for any value of x, there is only one value of y that can be plotted on the graph.
So the parabola is the graph that represents a function.

Describe and correct the error a student made in writing the exponential function.
Starting value 6
Constant ratio - 1/3
f(x) = 6(1/3)^x
f(x)=2^x
The correct equation of exponential function is [tex]f(x) = 6 * (\frac{1}{3} )^x[/tex]
What is an exponential function?
An exponential function is one that has the formula f (x) = [tex]a^{x}[/tex], where x is a variable and a constant that serves as the function's base and must be greater than 0.
Given,
starting value = 6
constant ratio = 1/3
The general form of an exponential function
[tex]f(x) = ab^{x}[/tex]
where a = starting value i.e when x = 0
b = rate of change in exponential equation
So substituting our given values in the above equation, the exponential function is
[tex]f(x) = 6 * (\frac{1}{3} )^x[/tex]
Now the value 6 can be divided by 3 only if the value of x = 1
[tex]f(1) =\frac{6}{3} = 2[/tex]
If x = 5, then equation becomes,
[tex]f(5) = 6 * (\frac{1}{3} )^5 = \frac{2}{81}[/tex]
So we cannot simply divide 6 by 3 without considering the value of x.
Therefore the correct equation of exponential function is

Tim went 8 miles east and 15 miles north. Jan went 5 miles west and 12 miles north. How far apart are they?
Answer:
30miles
Step-by-step explanation:
As you can see in the graph, the distance between tim and jan is creating 2 right triangles
You can solve this using pythagoras theorem,
Triangle (1) :
[tex] x^{2} = {5}^{2} + {12}^{2} \\ {x} = \sqrt{{5}^{2} + {12}^{2} } \\ = \sqrt{169 } \\ = 13[/tex]
X (1) = 13 miles
Triangle (2):
[tex] {x}^{2} = {15}^{2} + {8}^{2} \\ x = \sqrt{ {8}^{2} + {15}^{2} } \\ = \sqrt{289} \\ = 17 [/tex]
X(2) = 17 miles
Now, the distance = x(1) + x(2)
= 13 + 17
=30 miles
Therefore, Tim and Jan are 30 miles apart

Step-by-step explanation:
Formula for equation of circle when the radius r and centre (a,b) is given:
(x-a)² + (y-b)² = r²
(x-2)² + (y-3)² = 4²
Expanding the brackets;
x² - 4x + 4 + y² - 6x + 9 = 16
x² + y² - 4x - 6x + 4 + 9 = 16
x² + y² - 4x - 6x + 13 = 16
x² + y² - 4x - 6x + 13 - 16 = 0

Which division is shown by the model 3/4 / 1/8
Answer:
6
Step-by-step explanation:
For dividing fractions it's also useful to know that the first fraction (3/4) is called the dividend and the second fraction (1/8) is called the divisor.
Here is a really quick way to divide fractions. In the divisor (the second fraction) we flip the numerator and the denominator. This is known as the reciprocal and basically it means the reverse of the fraction. When we find the reciprocal, we also have to change the division sign to a multiplication sign:
3/4 times 8/1
Once you've flipped the second fraction and changed the symbol from divide to multiply, we can multiply the numerators together and the denominators together and we have our solution:
So we multiply the numerators: 3x8=24
Then multiply the denominators: 4x1=4
Then we have the inproper fraction 24/4
So we divide 24 by 4 to make the answer a proper fraction

the points (17,10) and (8,10) fall on a particular line. what is its equation in slope-intercept form?
The equation of the line that passes through the points (17,10) and (8,10) is y = 10.
What is slope?Slope is a measure of the steepness of a line or a linear function. It is often represented by the letter "m" and is calculated as the ratio of the change in the y-coordinates of two points divided by the change in the x-coordinates of those same two points. In other words, it is the ratio of the "rise" to the "run" of the line. The slope of a line can be positive, negative, zero, or undefined.
What is slope intercept form?The slope-intercept form of a linear equation is a way to represent the equation of a line in the form of y = mx + b, where m is the slope and b is the y-intercept of the line. The y-intercept is the point where the line crosses the y-axis, and it is represented by the value of b. This form of the equation is useful because it allows us to easily identify the slope and y-intercept of a line, as well as to graph the line using these values.
Calculate the slope (m) using the formula:
m = (y2 - y1) / (x2 - x1)
where (x1, y1) and (x2, y2) are the coordinates of the two points.
In this case, the slope is:
m = (10 - 10) / (8 - 17) = 0
Use the point-slope form of the equation, y - y1 = m(x - x1)
In this case, the point slope form is:
y - 10 = 0(x - 17)
Simplify the above equation, we get:
y = 10

2. Find a Star's Diameter. The supergiant star Betelgeuse (in the constellation Orion) has a measured angular diameter of 0.040 arcsecond from Earth and a distance from Earth of 720 light-years. What is the actual diameter of Betelgeuse? Compare your answer to the size of our Sun and the Earth-Sun distance.
The physical diameter of the sun will be 1309000km and the percentage of difference between the diameters will be 5.8%.
How to calculate the diameter?From the information, the sun has an angular diameter of about 0.5° and an average distance from the Earth of about 150 million km. The angular diameter in radians will be:
= 0.5π / 180
= 0.008727 radians
Distance from the sun = 150 × 10^6
The physical diameter of the sun will be:
= 150 × 10^6 × 0.008727
= 1309000km
The difference between the diameters will be:
= 1390000 - 1309000
= 8.1 × 10^4.
The percentage of difference will be:
