Answer:
cosβ
Step-by-step explanation:
cot(β+π)sinβ
cot(x)=cos(x)/sin(x), so we can rewrite our expression as:
(cos(β+π)/sin(β+π)) * sinβ
sin(a+b)=sin(a)cos(b)+cos(a)sin(b), so we can rewrite our expression as:
(cos(β+π)/(sinβcosπ+cosβsinπ)) * sin(β)
cos(a+b)=cos(a)cos(b)-sin(a)sin(b), so we can rewrite our expression as:
(cosβcosπ-sinβsinπ)/(sinβcosπ+cosβsinπ)) * sin(β)
cosπ=-1 and sinπ=0, so we can rewrite our expression as:
(-cosβ)/(-sinβ) * sin(β)
(-cosβ)/(-sinβ) * sin(β)
=(cosβ/sinβ)(sinβ)
=cosβ

The slope of the line below is -2. Write the point-slope equation of the line
using the coordinates of the labeled point.
Answer:
[tex]y+6=-2(x-4)[/tex]
Step-by-step explanation:
Point-slope form is a way of representing a line by using one of its points and the slope of a line. Its general format is the following,
[tex](y-y_1)=m(x-x_1)[/tex]
Where (m) represents the slope, ([tex]x_1[/tex]) and ([tex]y_1[/tex]) represents a point on the line.
It is given that the slope of the line is (-2), and that the line has point (4, -6). Substitute this into the formula.
[tex](y-(-6))=-2(x-4)[/tex]
[tex]y+6=-2(x-4)[/tex]

Four friends share 3 sheets of construction paper equally. What fraction
of a sheet of paper does each friend get?
Answer:
0.75 or 3/4 sheet of paper
Answer:
3/4 of each sheet
Step-by-step explanation:
You have to divide the number of sheets of paper by the number of people sharing them, which gives you 3/4. This makes sense because if there are more people than paper, each person will get less than a full sheet.

8/17
15/17
15/8
8/15
Answer:
15/8
Step-by-step explanation:
Assuming you mean tan theta
Tan(theta) = opposite/adjacent
We know the adjacent side is 8 so the bottom of the fraction must also be 8
C: 15/8 is the only option that fits this criteria
The value of tangent of the angle θ, i.e., tan θ = 15/8.
Hence the correct option is c.
Given is a right triangle, with base = 8 units and the hypotenuse is 17 units,
The angle θ which is between the base and the hypotenuse,
We need to find the value of tangent of the angle θ, i.e., tan θ.
To find the value of tangent (tan) of the angle θ, we can use the definition of tangent in a right triangle.
The tangent of an angle in a right triangle is equal to the ratio of the length of the side opposite the angle to the length of the side adjacent to the angle.
In this case, the base of the triangle is given as 8 units, and the hypotenuse is given as 17 units.
To find the length of the side opposite θ, we can use the Pythagorean theorem.
The Pythagorean theorem states that in a right triangle, the square of the length of the hypotenuse is equal to the sum of the squares of the lengths of the other two sides.
Using this theorem, we can calculate the length of the side opposite θ:
(side opposite θ)² + (base)² = (hypotenuse)²
(side opposite θ)² + 8² = 17²
(side opposite θ)² + 64 = 289
(side opposite θ)² = 289 - 64
(side opposite θ)² = 225
side opposite θ = √225
side opposite θ = 15 units
Now that we have the lengths of the side opposite θ and the side adjacent to θ, we can calculate the tangent of the angle θ:
tan θ = (side opposite θ) / (base)
tan θ = 15 / 8
Therefore, the value of tangent (tan) of the angle θ is 15/8.

Given Angle 1 =xº and angle 2 = (x +50)°.
Find the value of x. Then find angle 1 and 2
Answer:
x=65
Angle 1=65
Angle 2=115
Step-by-step explanation:
We know that angle 1 + angle 2 = 180. Writing it in terms of x, we get x + (x + 50)= 180. Then you have 2x+50=180. Subtracting 50 from both sides gives you 2x=130. Dividing both sides by 2, you get x=65. Angle 1 is 65 degrees. 180-65=115.

Which statement best explains whether y = 2x − 3 is a linear function or a nonlinear function?
It is a linear function because the graph contains the points (0, −3), (1, −1), (2, 1), which are on a straight line.
It is a nonlinear function because the graph contains the points (0, −3), (1, −1), (2, 1), which are not on a straight line.
It is a linear function because the graph contains the points (−3, 0), (−1, 1), (1, 2), which are on a straight line.
It is a nonlinear function because the graph contains the points (−3, 0), (−1, 1), (1, 2), which are not on a straight line.
Answer:
It is a linear function because the graph contains the points (0, −3), (1, −1), (2, 1), which are on a straight line.
Step-by-step explanation:
(0,-3) goes on the straight line perfectly
(1, −1) goes on the straight line perfectly
(2, 1) goes on the straight line perfectly
this means that it is a linear function due to all the points being on the line
hope this helps!
The given function y = 2x − 3 is a linear function because the graph contains the points (0, −3), (1, −1), (2, 1), which are on a straight line.
What is a linear function?A straight line on the coordinate plane is represented by a linear function.
How to solve this problem?Given function y = 2x − 3.
Clearly, it is a straight line.
At x = 0, y = 2*0 - 3 = 0 - 3 = - 3
At x = 1, y = 2*1 - 3 = 2 - 3 = - 1
At x = 2, y = 2*2 - 3 = 4 - 3 = 1
So, the given straight line passes through the points (0, -3), (1, -1), and (2, 1). Then the given function is a linear function.
Therefore, we can conclude that the given function y = 2x − 3 is a linear function because the graph contains the points (0, −3), (1, −1), (2, 1), which are on a straight line. So, the first option is correct.

in triangle ABC shown below, L is the midpoint of BC, M is the midpoint of AB, and N is the midpoint of AC. Find the perimeter of trapazoid BMNC.
35
since m and n are the midpoints of ab and ac resistively
then ,bc=2mn=16
since m and l are the midpoints of ba and bc respectively
then, ac =2mn =10
then,nc =1/2 × 10 =5

he National Center for Health Statistics interviewed 5409 adult smokers in 2015, and 2666 of them said they had tried to quit smoking during the past year. Consider this to be a random sample. Find a 95% confidence interval for the proportion of smokers who have tried to quit within the past year. (Round the final answers to three decimal places.) The 95% confidence interval is ( , ).
Answer:
95% confidence interval for the proportion of smokers who have tried to quit within the past year
(0.47956 ,0.50620)
Step-by-step explanation:
Step(i):-
Given that National Center for Health Statistics interviewed 5409 adult smokers in 2015
Sample size 'n' = 5409
Given that 2666 of them said they had tried to quit smoking during the past year.
proportion
[tex]P = \frac{x}{n} = \frac{2666}{5409} = 0.49288[/tex]
Q = 1 - P = 1 - 0.49288 = 0.50712
Step(ii):-
95% confidence interval for the proportion of smokers who have tried to quit within the past year
[tex]({P - Z_{0.05} \sqrt{\frac{PQ}{n} } , P + Z_{0.05} \sqrt{\frac{PQ}{n} )[/tex]
[tex]({0.49288 - 1.96 \sqrt{\frac{0.49288 X 0.50712}{5409} } , 0.49288 + 1.96\sqrt{\frac{0.49288 X 0.50712}{5409} )[/tex]
