The equation of the line would be y - 20 = 12(x - 1).
Option (C) is correct.
What is the slope-point form of the line?
For the line having slope "m" and the point (x1, y1) the equation of the line passing through the point (x1, y1) having slope 'm' would be
y - y1 = m(x - x1)
Let's suppose on the y-axis there will be a number of copies sold and on the x-axis, there will be a number of days.
On day 1, he sold 20 copies so point would be (1, 20)
On day 2, he sold 32 copies so point would be (2, 32)
Slope of the line = (y2 - y1)/(x2 - x1)
= (32 - 20)/(2 - 1)
m = 12
By using the slope-point form of the line,
y - y1 = m(x - x1)
y - 20 = 12(x - 1)
Hence, the equation of the line would be y - 20 = 12(x - 1).

F = (9/5)C + 32.
What is unit conversion?The same attribute is expressed using a unit conversion but in a different unit of measurement. For instance, time can be expressed in minutes rather than hours, and distance can be expressed in kilometers, feet, or any other measurement unit instead of miles.
We know we can convert temperatures from celsius to fahrenheite or from fahrenheite to celsius.
The conversion of celsius to fahrenheit is given by the formula,
C = (5/9)(F - 32).
Now, we have to solve for F.
C = (5/9)F - (160/9).
Now to get rid of the fraction we'll multiply 9 to each term.

Answer:
[tex]AB = 4.5[/tex]
Step-by-step explanation:
⭐To find the distance between two points, you can use the distance formula: [tex]d = \sqrt{(x_2-x_1)^2 +(y_2 - y_1)^2}[/tex], where:
d = the distance[tex](x_1, y_1)[/tex] is one coordinate you want to find the distance from[tex](x_2, y_2)[/tex] is another coordinate you want to find the distance fromFirst, identify the coordinates you need to find the distance between, and label one coordinate as [tex](x_1, y_1)[/tex] and [tex](x_2, y_2)[/tex].
A(-1,2) = [tex](x_1, y_1)[/tex] = (-1,2)B(1,-2) = [tex](x_2, y_2)[/tex] = (1,-2)Next, substitute [tex](x_1, y_1)[/tex] and [tex](x_2, y_2)[/tex] into the distance formula.
[tex]d = \sqrt{(1-(-1))^2+(-2-2)^2}[/tex]
[tex]d = \sqrt{(1+1)^2+(-4)^2}[/tex]
[tex]d = \sqrt{2^2+(-4)^2}[/tex]
[tex]d = \sqrt{4+16}[/tex]
[tex]d = \sqrt{20}[/tex]
∴ d ≈ 4.5
Solve the formula for b.
Answer:
[tex]b=\dfrac{2V}{ah}-c[/tex]
Step-by-step explanation:
Given equation:
[tex]V=\dfrac{1}{2}a(b+c)h[/tex]
Multiply both sides of the equation by 2:
[tex]\implies 2 \cdot V=2 \cdot \dfrac{1}{2}a(b+c)h[/tex]
[tex]\implies 2V=a(b+c)h[/tex]
Divide both sides by ah:
[tex]\implies \dfrac{2V}{ah}=\dfrac{a(b+c)h}{ah}[/tex]
[tex]\implies \dfrac{2V}{ah}=b+c[/tex]
Subtract c from both sides:
[tex]\implies \dfrac{2V}{ah}-c=b+c-c[/tex]
[tex]\implies \dfrac{2V}{ah}-c=b[/tex]
Therefore:
[tex]\implies b=\dfrac{2V}{ah}-c[/tex]

A. From the Limit Comparison Test, the series converges conditionally.
The Limit Comparison Test can be used to determine whether a given series converges or diverges. In this case, the given series is sigma^infinity_k = 0 9(-1)^k/k^4 + 2.
To use the Limit Comparison Test, we need to compare the given series to a known series. For example, we can compare it to the series sigma^infinity_k = 1/k^4.
We can then calculate the ratio of the two series:
sigma^infinity_k = 0 9(-1)^k/k^4 + 2
sigma^infinity_k = 1/k^4
Ratio: sigma^infinity_k = 0 9(-1)^k / (1/k^4)
Since the limit of the ratio of two series is a finite number, the given series converges. However, since the ratio is not 1, it converges conditionally, not absolutely.
Therefore, the answer is A - From the Limit Comparison Test, the series converges conditionally.

What is the formula for consecutive odd numbers?
The equation for adding "n" numbers in a row is [a + (a + 1) + (a + 2) +.... a + (n-1)]. As a result, (n/2) (first number + last number) is the sum of "n" consecutive numbers or "n" terms of AP (Arithmetic Progression). The formula for even consecutive numbers is 2n, 2n+2, 2n+4, 2n+6, and so on.
The next two odd consecutive integers are (2n + 3) and (2n + 5) if 2n + 1 is an odd number. For illustration, assume that 2n + 1 is the odd number 7. Its successive numbers are identified as (7 + 2) and (7 + 4), or 9 and 11. Consecutive odd numbers are odd integers that are separated by 2 and come after one another. If the number x is odd, then the numbers x + 2, x + 4, and x + 6 are also odd.
Any collection of consecutive odd numbers starting with 1 has a sum that is always equal to the square of the total number of digits. If the numbers 1, 3, 5, 7, 9, 11,..., and (2n-1) are odd, then the sum of the first odd number is 1. First two odd numbers added together equal 1 + 3 = 4 (4 = 2 x 2). Two successive odd numbers added together are always divisible by 4.

The circumference of a circle is 13π cm. What is the area, in square centimeters? Express your answer in terms of \piπ.
Answer:
The circumference of a circle is given by the formula $C = 2\pi r$, where $r$ is the radius of the circle. In this case, the circumference of the circle is $13\pi$ cm, so we can set up the equation $13\pi = 2\pi r$ to solve for the radius. Dividing both sides by $2\pi$, we get $r = \frac{13\pi}{2\pi} = \frac{13}{2}$ cm. The area of a circle is given by the formula $A = \pi r^2$, so the area of this circle is $A = \pi \left(\frac{13}{2}\right)^2 = \frac{169}{4}\pi$ square cm. Therefore, the area of the circle is $\frac{169}{4}\pi$ square cm.

Why is it called line graph?
It is formed by simply drawing lines connecting the data points. Also called linear chart.
A line chart is a graphical representation of changes that occur over a period of time. A line chart has a horizontal axis called the x-axis and a vertical axis called the y-axis. The x-axis usually has a period of time over which we want to measure the quantity of a particular thing or item on the y-axis. Line charts are useful for analyzing trends, whether the quantity on the y-axis is increasing or decreasing over time. A line chart clearly shows an uptrend or a downtrend.
The line chart above represents bike sales by bike company from January to June, with the x-axis representing the time interval and the y-axis representing the number of bikes sold per month. Black dots in the graph indicate data points. A data point in a line chart represents the magnitude or number corresponding to a specific time on the x-axis. In this example, 50 bikes were sold in January. 30 bikes were also sold in February. This data can be interpreted by month using data points. Line segments connecting these individual data points show whether bike sales are trending upwards or downwards.

(b) Best widthWe notice this function describes a parabola that opens downward, with zeros at x=0 and x=64. The vertex (maximum) is on the line of symmetry, halfway between the zeros:
x = (0 +64)/2 = 32
The width that maximizes area is x = 32 ft.
(c) Maximum areaUsing x=32 in the area formula, we find the maximum area to be ...
A(32) = 32(64 -32)/2 = 1024/2 = 512 . . . . square feet
The maximum area is 512 square feet.

Additional comment
Perhaps you can see that the best width is half the length of the available fence. The other half of the fence is used for the ends of the enclosure. This is the generic solution to this kind of problem.
