Answer:
Options 1, 2 and 4 are correct
Step-by-step explanation:
We should determine few things;
Sine = [tex]\frac{opposite}{hypotenuse}[/tex]
Cosine = [tex]\frac{Adjacent}{Hypotenuse}[/tex]
Tangent = [tex]\frac{Opposite}{Adjacent}[/tex]
The values of Opposite and Adjacent vary by the angle given, however Hypotenuse always remains the same, the length opposite to the right angle is hypotenuse.
Now we can say that;
Sin (53) = [tex]\frac{opposite}{hypotenuse}[/tex] [tex]= \frac{21}{29}[/tex]
Sin (37) = [tex]\frac{opposite}{hypotenuse}[/tex] [tex]=\frac{20}{29}[/tex]
Tan (53) would be [tex]\frac{Opposite}{Adjacent}[/tex] [tex]=\frac{21}{20}[/tex], not [tex]\frac{20}{21}[/tex]
Cos (37) = [tex]\frac{Adjacent}{Hypotenuse}[/tex] [tex]= \frac{21}{29}[/tex]
Hope this helps!

Review the graph of g(x).
On a coordinate plane, a curve goes through (negative 4, 8), curves down through (negative 2, 0), and approaches x = negative 1 in quadrant 3. Another curve approaches x = negative 1 in quadrant 2, has vertex (0, 0), and curves up through (2, 8). Another curve approaches x = 3 in quadrant 4 and curves up through (4, 16).

Does a triangle with these side lengths exist?
28, 41, 13
Answers
Answer:
No
Step-by-step explanation:
it doesnt add up to 180 degrees
Use the triangle inequality theorem.
Add two sides together and see if it is greater than the length of the 3rd side:
28 + 41 = 69 which is greater than 13
41 + 13 = 54 which is greater than 28
28 + 13 = 41 this is equal to the 3rd side length of 41 and not greater than 41
Because 28 + 13 is not greater than 41 those 3 lengths cannot make a triangle.

17) -4y + 16 = 6x
Isolate the variable, y. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS.
First, subtract 16 from both sides of the equation:
-4y + 16 (-16) = 6x (-16)
-4y = 6x- 16
Next, divide -4 from both sides of the equation:
(-4y)/-4 = (6x - 16)/-4
y = (6x)/-4 + (-16)/-4
y = -3x/2 + 4
Slope: [tex]-\frac{3}{2}[/tex]
~
18) 0 = -12y -36 + 15x
Isolate the variable, y. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS.
First, add 12y to both sides of the equation:
0 (+12y) = - 12y (+12y) + 15x - 36
12y = 15x - 36
Next, divide 12 from both sides of the equation to isolate the variable, y:
(12y)/12 = (15x - 36)/12
y = (5/4)x - 3
Slope: [tex]\frac{5}{4}[/tex]
~
19) 3x = -6y
Isolate the variable, y. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS.
Divide -6 from both sides of the equation:
(3x)/-6 = (-6y)/-6
y = 3x/-6
y = -(3/6)x
Simplify. Divide common factors from both the numerator and denominator.
-(3/6)/(3/3) = - 1/2
Slope: [tex]-\frac{1}{2}[/tex]
~
20) -2x -5 = -5y
Isolate the variable, y. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS.
Divide -5 from both sides of the equation:
(-2x - 5)/-5 = (-5y)/-5
y = (-2x - 5)/-5
y = (2/5)x + 1
Slope: [tex]\frac{2}{5}[/tex]

Yes, because angle 3 and angle 6 are congruent.
Yes, because angle 5 and angle 6 are supplementary.
Answers

Answer:
(c) Yes, because angle 3 and angle 6 are congruent
Step-by-step explanation:
Angles 3 and 6 are "alternate interior" angles. When those angles are congruent, as these are, then the lines crossed by the transversal are parallel.
__
We expect angles 5 and 6 to be supplementary because they are a linear pair. That fact says nothing about the relationship of line d to line c.
Answer:
C) Yes, because angle 3 and angle 6 are congruent.

D

Answers
Answer:
A:37
Step-by-step explanation:
A school got 5 copies, and the total for ALL the copies is $185. So you need to take 185 and divide it by 5 because we need to find out how much each of the copies costs. If you do that then you will get the answer of $37 per copy
The price for each copy is $37 if the school bought 5 copies of a textbook this week the school spent a total of $185 on the 5 copies option (A) is correct.
What is a fraction?Fraction number consists of two parts one is the top of the fraction number which is called the numerator and the second is the bottom of the fraction number which is called the denominator.
We have:
Number of copies school bought = 5
Price for 5 copies = $185
Let's assume the price for each copy = $x
So the value of x can be evaluated:
[tex]\rm x = \frac{185\times1}{5}[/tex]
x = $37
Thus, the price for each copy is $37 if the school bought 5 copies of a textbook this week the school spent a total of $185 on the 5 copies option (A) is correct.

A rectangle has an area of 226.1 square miles and a base of 13.3 miles. What is the height?
Answers
Answer:
The width (in our case it is the height) of the rectangle equals 17 miles
Step-by-step explanation:
In order to solve this, we need to know the following...
Area of a rectangle = Length x Width
(in our case based on what you said length is the base and width is the height)
Now we just change the formula to our needs and get that...
Width = Area of the rectangle / Length
And so we get...
Width = Area of the rectangle / Length
Width = 226.1 / 13.3
Width = 17 miles

9. A wheel has a radius of 9 inches and
travels as it spins. How far does the
wheel travel in one revolution? Show your
work. Use 3.14 for n and round to the
nearest inch,
Answers
Answer:
57inches
Step-by-step explanation:
In order to determine how far the wheel travels, we will have to find the circumference of the wheel. This is expressed as;
Circumference of the wheel = 2πr
r is the radius of the wheel = 9in
Substitute
Circumference of the wheel = 2(3.14)(9)
Circumference of the wheel = 56.52inches
Hence the wheel travels 57inches to the nearest inch
