Answer:
Sine - opposite side/hypotenuse. Sine is the ratio of the opposite side to the hypotenuse.
Cosine - adjacent side/hypotenuse. Cosine is the ratio of the adjacent side to the hypotenuse.
Tangent - opposite side/adjacent side. Tangent is the ratio of the opposite side to the adjacent side.
Answer:
Three common trigonometric ratios are the sine (sin), cosine (cos), and tangent (tan)

Answer:
Use Pythagorean Theorem to find the distance between the two points
[tex]x^{2} +y^{2} =r^{2}[/tex] where r is the distance between the two points
Δx = 6-4 = 2
Δy = 3-(-1) = 4
2²+4²=r²
4+16=r²
20=r²
√20=r
r=4.47
r=4.5
4.5÷2=2.25 (halfway)
∴The distance between the cafeteria and the bathrooms is 2.25 units
Hopefully you understand how I got this answer.
Answer:
(5,1)
Step-by-step explanation:
So for this one we just find the length between the x values and the length between the y values and divide by 2 to find how far it will be ( if that makes sense.)
the distance between the two x values is 2 and the distance between the two y values is 4
2/2 = 1 and 4/2 = 2
then we subtract 1 from the x value and 2 from the y value ( using the coordinates of the cafeteria btw.)
6-1=5 and 3-2 =1 so the coordinates of the bathroom is (5,1)

Answer:
Step-by-step explanation:
2(x + 15)⁰ + (3x + 20)⁰=180⁰
2x + 30⁰ + 3x + 20⁰=180⁰
2x + 3x + 30⁰ + 20⁰=180⁰
5x + 50⁰ - 50⁰=180⁰-50⁰
5x=130⁰
5x/5=130⁰/5
x=26⁰
Answer:
x should equal 26.
Step-by-step explanation:
since they are cointerior angles:
2 (x + 15) + (3x + 20) = 180
2 (x) + 2 (15) + (3x + 20) = 180
2x + 30 + (3x + 20) = 180
2x + 30 + 3x + 20 = 180
5x + 50 = 180
5x + 50 - 50 = 180 - 50
5x = 130
5 ÷ 5x = 130 ÷ 5
x = 26

The value of x from the given equation is -2.
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 equation is 4(x - 2) + 3 = 2x - 9.
The solution of an equation is the set of all values that, when substituted for unknowns, make an equation true.
4x-8+3=2x-9

A shooting star forms a right triangle with the Earth and the Sun, as shown below: A right triangle is shown with the vertices labeled Earth, Sun, and Shooting Star. The angle formed by the Sun is labeled x deg A scientist measures the angle x and the distance y between the Earth and the shooting star. Which trig function would the scientist use to calculate the distance between the Earth and the Sun. (5 points) sin cos tan sin-1 cos-1 tan-1
Answer:
The answer is below
Step-by-step explanation:
A triangle is a polygon with three sides and three angles. There are different types of triangles such as scalene triangle, obtuse triangle, equilateral triangle and right angled triangle.
Trigonometric functions are functions used to show the relationship between an angle of a right-angled triangle and the ratio of two side lengths. Below are some trigonometric function:
sinθ = opposite/hypotenuse, cosθ = adjacent/hypotenuse, tanθ = opposite/adjacent.
Given the right angled triangle with angle x. and the hypotenuse y. We need to find the distance between the Earth and the shooting star.
d = distance between the Earth and the shooting star = adjacent side.
Therefore, the relationship between angle x, d and y can be gotten using the cos trig function.
cosθ = adjacent / hypotenuse
cos(x) = d / y
d = y * cos(x)

Step-by-step explanation:
your maximum "point" of the polynomial is the highest point that the curve makes which in this case is around x=-3.6 and y=17
The point of maxima for the given function is (-3.6, 17).
What is a function?A function y = f(x) is a one to one relationship between two sets X and Y where the set X is called the domain and Y the range of function f(x) ans x ∈ X and y ∈ Y.
As per the graph of the function following conclusion are as below,
It has a maxima in second quadrant.
After the point of maxima, its value starts to decrease.
Then, it reaches it lowest value in fourth quadrant after which it increases again.
By examining the given options, the correct point of maxima can be found as (-3.6, 17).
Hence, the point of relative maxima for the graph can be evaluated as (-3.6, 17).

Mr. Reed is drawing a blueprint of a rectangular patio. The width of the patio is 40 3/4 feet shorter than twice its length. The perimeter of the patio 86 1/2 feet what is the length of the patio?
Answer:
Length of rectangular patio = 28 feet
Step-by-step explanation:
Given that:
Length of rectangular patio = x
Width of rectangular patio = [tex]2x-40\frac{3}{4}[/tex]
Perimeter of rectangular patio = [tex]86\frac{1}{2}[/tex]
Perimeter of rectangular patio = 2 (length + width )
Putting values in the formula
[tex]86\frac{1}{2}=2(x+2x-40\frac{3}{4})\\\\\frac{173}{2}=2(3x-\frac{163}{4})\\\\\frac{173}{2}=2(\frac{12x-163}{4})\\\\\frac{173}{2}=\frac{12x-163}{2}\\\\173 = 12x-163\\12x = 173 + 163 \\12x = 336[/tex]
Dividing both sides by 12
[tex]\frac{12x}{12}=\frac{336}{12}\\x=28[/tex]
Hence,
Length of rectangular patio = 28 feet

Daniel works at a nearby electronics store. He makes a commission of 15% on everything he sells. If he sells a laptop for $450, a wireless speaker for $82, and a set of wireless headphones for $120, how much money does Daniel make in commission?
Answer:
$97.80
Step-by-step explanation:
Answer:
$97.70
Step-by-step explanation:
So to find percent
450/100= 4.5 ,4.5x15= 67.5
82/100=0.82 0.82x15= 12.2
120/100=1.2 1.2x15=18
So do 67.5+12.2+18= $97.70
