Answer:
I believe the textbook is telling you which rounded version of pi () to use when solving questions regarding the geometry of circles. This is not a definite answer, as the question you asked is not completely clear cut. It is only my best attempt to interpret what your textbook means.
Answer:
Arc length
formula = s = rθ
s = arc length (in radians)
r = radius
θ = central angle in radians
Step-by-step explanation:
For a circle, the arc length formula is θ times the radius of a circle. The arc length formula in radians can be expressed as, arc length = θ × r, when θ is in radian. Arc Length = θ × (π/180) × r, where θ is in degree, where, L = Length of an Arc.
where X = 60,2 degree

The accompanying data set lists the numbers of children of world leaders. Use the data to construct a frequency distribution using six classes and to create a frequency polygon. Describe any patterns.
Answers
Frequency polygons are used to show the trend between the elements of a given dataset and the frequency of each element.
From the dataset, we have the following class of 6 and the frequency:
[tex]Class \to Frequency[/tex]
[tex]0 - 2 \to 9[/tex]
[tex]3 - 5 \to 18[/tex]
[tex]6 - 8 \to 7[/tex]
[tex]9 - 11\to 0[/tex]
[tex]12 - 14 \to 5[/tex]
[tex]15 - 17 \to 4[/tex]
So, the frequency distribution is as follows:
[tex]\begin{array}{ccc}{Class}&{Frequency}&{x}\\0-2&9&1\\3-5&18&4\\6-8&7&7\\9-11&0&10\\12-14&5&13\\15-17&4&16\end{array}\right][/tex]
The class midpoint (x) is calculated by calculating the mean of each class.
For instance, the midpoint (x) of class 0 - 2 is:
[tex]x = \frac{1}{2}(0+2) = \frac{1}{2} \times 2 =1[/tex] ---- and so on
The class midpoint (on the x-axis) is plotted against the frequency (on the y-axis) to create the frequency polygon (see attachment)

Jae is a real estate photographer. The amount he earns in one week is a linear function of the number of houses he photographs.
If he photographs 2 houses, he earns $315, and if he photographs 7 houses, he earns $1015.
a. Create a linear model for Jae's earnings (y) (in dollars) as a function of the the number of houses he photographs (x), and put
the model in slope-intercept form.
Answers
Equation of a linear function is defined by equation y = mx + b,
where m = slope of the line and b = y-intercept
Linear model representing a function for the earning (y) to photograph the houses (x) will be,
y = 140x + 35
Let the linear equation representing the earnings to photograph the houses,
y = mx + b
If we graph a line with two variables, earnings from photography on y-axis and the number of houses at x-axis,
Slope of the line 'm' = [tex]\frac{\triangle y}{\triangle x}[/tex]
If two points lying on the line are (2, 315) and (7, 1015).
Slope of the line 'm' = [tex]\frac{1015-315}{7-2}[/tex]
= [tex]\frac{700}{5}[/tex]
= 140
Therefore, equation of the line will be,
y = 140x + b
Since, (2, 315) lies on the line,
315 = 140(2) + b
315 = 280 + b
b = 35
Now the equation will be,
y = 140x + 35
Therefore, linear model representing a function of the earning (y) to photograph the houses (x) will be,
y = 140x + 35

Paul bought a student discount card for the bus. The card allows him to buy daily bus passes for $1.40.
After one month, Paul bought 19 passes and spent a total of $31.60.
How much did he spend on the student discount card?
Paul spent $________
on the student discount card.
Answers
Answer:
$5
Step-by-step explanation:
First, we need to find the total amount he spent on the passes.
We just need to multiply the number of passes by the price of each pass.
19 x 1.4 = 26.6
This means he spent $26.6 on the passes.
Now, we can find out how much he spent on the discount card.
Just subtract his total spending amount by the amount he spent on passes.
31.6 - 26.6 = 5
He spent $5 on the discount card.

256/2 = 128128/2 = 6464/2 = 3232/2 = 1616 = 2^4, so 256 = 2^4 · 2 · 2 · 2 · 2 = 2^8The 8th root of 2^8 is 2, choice A.

The equation to represent the given phrase is 2p-4=-12.
What is an equation?In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.
The given phrase is "Negative twelve is four less than twice a number, p."
Here, four less than twice a number, p is
2p-4
The difference is equal to -12.
Now, 2p-4=-12
The solution of an equation is the set of all values that, when substituted for unknowns, make an equation true.
Here, transpose -4 to the other side of an equation, we get
2p=-12+4
2p=-8
p=-2
Therefore, the value of p is -2.
