The trigonometric functions sin θ = - 2 / 3 and csc θ = - 3 / 2 are related to each other in accordance with the trigonometric formula: sin θ · csc θ = 1. (Correct choices: 1, 4)
What two trigonometric functions have the same angle?
In this question we must look for two trigonometric functions that are associated to one and same angle. This can be done by relations between fundamental and derivate trigonometric functions. There are two fundamental trigonometric functions (sine, cosine) and four derivate trigonometric functions (tangent, cotangent, secant, cosecant).
After a quick inspection, sin θ = - 2 / 3 is related to csc θ = - 3 / 2 as it fulfill the following trigonometric formula: sin θ · csc θ = 1
RemarkThe graph is missing and cannot be found, so we decided to change the intend of the question to find two trigonometric functions associated with the same angle.

A line's slope is a measurement of how steep a line is. Slope is calculated by dividing the change in y values by the change in x values.
In math, what is a slope?A line's steepness can be determined by looking at its slope. Slope is calculated mathematically as "rise over run" (change in y divided by change in x).
Slope is a measure of the steepness of a line.
Slope = rise / run = Δy / Δx.
Slope= Δx /Δy = 4−0 /2−5 = 4 / −3
Slope from two points, for instance

If the volume of a prism is 64, its length 4, and its width 2, what is its height
Answer:
h=8
Step-by-step explanation:
there is a formula for a volume of a prism
Volume = length • width • height
for shortening purposes
V = L • W • H
we know the prism's length is 4, and it's width is 2 and we know it's volume is 64 but the height is missing
what we will do is say (since height is missing)
[tex]h = \frac{V}{l \: • \: w} [/tex]
v = 64
l = 4
w = 2
so, now plug in those values for your variables
[tex]h = \frac{64}{4 \: • \: 2} [/tex]
multiply 4 • 2
[tex]h = \frac{64}{8} [/tex]
divide by 8
[tex]h = \frac{8}{1} [/tex]
simplify
[tex]h = 8[/tex]
Check:V = l•w•h
v= 4 • 2 • 8
v = 8• 8
v = 64

For the line and point below, describe how the following equations would differ: A) A parallel line, through the given point B) A perpendicular line, through the given point (-2,1) slope 1
The linear functions would be given as follows:
a) Parallel: y = x + 3.
b) Perpendicular: y = -x - 1.
The equations have different slope and intercept.
What is a linear function?A linear function, in slope-intercept format, is modeled according to the following rule:
y = mx + b
In which the coefficients are described as follows:
The coefficient m is the slope of the function, which is the rate of change of the function, that is, the change in y divided by the change in x.The coefficient b is the y-intercept of the function, which is the the value of y when the function crosses the y-axis(x = 0).For item a, we consider that if two lines are parallel, they have the same slope, hence the line would also have a slope of 1, that is:
y = x + b.
From point (-2,1), we have that when x = -2, y = 1, hence we can solve and find the intercept b as follows:
1 = -2 + b
b = 3.
Hence:
y = x + 3.
For item b, we consider that if two lines are perpendicular, the multiplication of their slopes is of -1, hence:
m = -1.
Then:
y = -x + b.
From the point (-2,1), we can find b as we did above, hence:
1 = -(-2) + b
2 + b = 1
b = -1.
Hence the rule is:
y = -x - 1.
The equations have different slope and intercept, that is, their coefficients are different.

how do I find which two further transformations will carry rectangle P'Q'R'S back onto rectangle PQRS
Reflection across the x axis involve negating the value of the y axis but the value of the x axis remain the same. Reflection across the y axis negate the x coordinates but the y values remains the same. When you reflect across the line y=x the coordinate and the y coordinates change places. Whe it rotate 180 degree around the origin the x and y values are negated. The transformation is interpreted as follows.
The answer is C which is reflection across the y axis followed by a 180 degree rotation around the origin.
The logic here is that PQRS is first reflected across the x axis which makes the y values negative. Then it reflect across the y axis which makes the value of x negative. So both x and y values are negative at this point. The rotation of 180 degree around the origin negates both the x and y values to make it all positive like the initial values of PQRS.

b)
[tex]\sf A = \dfrac{a+b}{2}\\\\\text{Multiply the entire equation by 2,}\\\\2*A = 2*\dfrac{a+b}{2}\\\\2A = a+b\\\\\text{Now subtract 'a' from both sides,}\\\\2A - a = b\\\\\boxed{b=2A - a}[/tex]
c)
[tex]\sf F =\dfrac{Gm_1m_2}{r^2}[/tex]
Multiply the entire equation by r²,
[tex]\sf Fr^2=r^2*\dfrac{Gm_1m_2}{r^3}\\\\Fr^2=Gm_1m_2[/tex]
Divide the entire equation by Gm₂,
[tex]\sf \dfrac{Fr^2}{Gm_2}=m_1\\\\\boxed{m_1=\dfrac{Fr^2}{Gm_2}}[/tex]
D) A = 7 ; y =4
Substitute in the equation and find the other number.

solve each compound inequality. drag the correct solution and graph next to the inequality
A compound inequality is created by joining two or more inequalities together using or or and (also known as a combined inequality). For a value to be the answer to an or inequality, it simply needs to make one part of the inequality true. To be effective, a solution to an inequality must make both sides true. Examples are x3 or x>2.
Explain about the compound inequality?
A sentence having two inequality statements connected by the words "or" or "and" is referred to as a compound inequality. The conjunction "and" denotes the simultaneous truth of both statements in the compound sentence. It is when the solution sets for the various statements cross over or intersect.
Divide a compound inequality into two independent ones before attempting to solve it. Choose either a union of sets ("or") and an intersection of sets as the appropriate response ("and"). Then, resolve the graph and all inequalities.
The values that belong to both graphs—where the graphs overlap—are found by first examining the graphs of each individual inequality in order to obtain the answer to a "and" compound inequality. We graph each inequality for the compound inequality x>3 and x2. Next, we search for areas where the graphs "overlap."

Functions y=x and y=x-3 are related in a way that each output for y=x–3 is 3 units more than the corresponding output for y=x.
Their graphs are related in a way that the graph of y=x–3 is the graph of y=x translated down 3 units
A function will defines one variable in terms of the other. Functions y=x means that y will vary directly to whatever value x takes.
When the graph of function y=x is drawn, then it is a straight line through the origin.
Now, functions y=x and y=x-3 are closely related. The graphs of the two are almost the same, the only difference is that every point on function y=x has been lowered by 3 to be function y=x-3.
Hence, the output for y=x-3 is 3 units more than the output of y=x, and the graph of function y=x is translated down by 3 units to get function y=x-3

Using the properties of percentage we get that the shirt cost $0.25 more in Fresno than in Bakersfield.
A percentage is a figure or ratio stated as a fraction of 100 in mathematics.
Although the abbreviations "pct.", "pct.", and occasionally "pc" are also used, the percent symbol, "%," is frequently used to indicate it. A percentage lacks dimensions and has no associated unit of measurement.It is not always obvious from the context what a percentage is in relation to because of inconsistent usage. The typical meaning of a "10% rise" or "10% decline" in a quantity is that this refers to the quantity's starting value. As an illustration, the new price of a $200 item would be $220 if the price increased by 10%, or $20.Price of the shirt is Fresno
= 35 + 8.225% of 35
= 37.87875
≈ 37.88 dollars
Price of the shirt in Bakersfield
= 35 + 7.5% of 35
