What are the trigonometric ratios?Trigonometric ratios are the ratio of sides of a right angled triangle. There are 6 types of trigonometric ratios: sin, cos, tan, cosec, sec, and cot.
Sine trigonometric ratio is the ratio of perpendicular (side opposite to the angle) to the hypotenuse.
In the given figure, the side opposite to the angle [tex]\beta[/tex] is AC = 4 and the hypotenuse is AB = 5.
So, the sine ratio will be equal to,
[tex]\sin \beta=\dfrac{4}{5}[/tex]
Therefore, the value of [tex]\sin \beta[/tex] in the given triangle ABC is [tex]\dfrac{4}{5}[/tex]. Option D is correct.

help me pls, will mark brainliest!!!!!!!!!!!!!
Step-by-step explanation:
since he was already on time on the first day, the question is reduced to the probability of being on time on exactly one of the next 2 days.
the probability to be on time on exactly one day means to be on time on one day and to be late on the other.
the probability to be late is the opposite of the probability to be on time, so
1 - 0.7 = 0.3
so, the probability for this combined event for one of the day combinations is
0.7 × 0.3 = 0.21
how many day combinations (1 day on time, the other late) can we have ? 2 (either on time on the first and late on the second, or late on the first and on time on the second).
so, we need to multiply this with the basic probability and get
0.21 × 2 = 0.42
so, b. is the right answer.

if you were asked to convert the complex number, -6 + 8i, into polar form, what values of “r” and “0” would be in polar form?
Answer:
10∠126.87°
r = 10; θ = 126.87°
Step-by-step explanation:
The coordinate conversion from (x, y) or (x +yi) to (r; θ) can be done using the relations ...
r = √(x² +y²)
θ = arctan(y/x) . . . . paying attention to quadrant
__
For the given complex number, we have ...
r = √((-6)² +8²) = √(36 +64) = √100 = 10
θ = arctan(8/(-6)) = arctan(-4/3) . . . . in the 2nd quadrant
θ ≈ -53.13° +180° = 126.87°
The equivalence is ...
-6 +8i ⇔ 10∠126.87° . . . . . in the form r∠θ

how would I solve y=9(x+3)(x-1) I need to find the vertex and the X intercepts
Answer:
See below ~
Step-by-step explanation:
Finding the x-intercepts :
The x-intercept's y-value is always 00 = 9(x + 3)(x - 1)x + 3 = 0 ⇒ x = -3x - 1 = 0 ⇒ x = 1So, hence the x-intercepts are : (-3, 0) and (1, 0)Finding the vertex :
Expand the polynomial from factorized formy = 9(x + 3)(x - 1)y = 9(x² + 3x - x - 3)y = 9(x² + 2x - 3)y = 9x² + 18x - 27Vertex = (h, k)h = -b/2a = -18/2(9) = -1k = 9(-1 + 3)(-1 - 1)k = 9(2)(-2)k = 9(-4) = -36Vertex = (-1, -36)Answer:
x-intercepts: x = 1 and x = -3
vertex: (-1, -36)
Step-by-step explanation:
x-interceptsx-intercepts are when y = 0
⇒ 9(x + 3)(x - 1) = 0
Divide both sides by 9:
⇒ (x + 3)(x - 1) = 0
Therefore:
⇒ (x + 3) = 0 ⇒ x = -3
⇒ (x - 1) = 0 ⇒ x = 1
Therefore the x-intercepts are x = 1 and x = -3
VertexVertex form: [tex]y=a(x-h)^2+k[/tex] where (h, k) is the vertex
Completing the square
[tex]\begin{aligned}y & =ax^2+bx+c\\& =a\left(x^2+\dfrac{b}{a}x\right)+c\\\\& =a\left(x^2+\dfrac{b}{a}x+\left(\dfrac{b}{2a}\right)^2\right)+c-a\left(\dfrac{b}{2a}\right)^2\\\\& =a\left(x-\left(-\dfrac{b}{2a}\right)\right)^2+c-\dfrac{b^2}{4a}\end{aligned}[/tex]
Therefore:
[tex]y=9(x+3)(x-1)[/tex]
[tex]\implies y=9x^2+18x-27[/tex]
Completing the square to rewrite the equation in vertex form:
[tex]\begin{aligned}y & =9x^2+18x-27\\& =9\left(x^2+\dfrac{18}{9}x\right)-27\\\\& =a\left(x^2+\dfrac{18}{9}x+\left(\dfrac{18}{2(9)}\right)^2\right)-27-9\left(\dfrac{18}{2(9)}\right)^2\\\\& =9\left(x-\left(-\dfrac{18}{2(9)}\right)\right)^2-27-\dfrac{18^2}{4(9)}\\\\& =9(x+1)^2-36\end{aligned}[/tex]
Therefore, the vertex is (-1, -36)
Choose the equation for the relationship shown in the graph.
A) y = x + 50
B) y = x – 50
C) y = 50 - x
D) x = 50 - y
Answer:
B) y = x - 50
Step-by-step explanation:
It is B because the graph's y-intercept lies on the point (0, -50), hence the equation, y = x - 50. In addition, you can verify that B is the correct answer because the slope of the graph is positive, and so the x-value also must be positive.

Ailsa is twice as old as Barbara. Ailsa is 5 years younger the candy. the average age of candy ailsa and Barbara is 15. determine candys age
Answer:
Candy is 21 years old
Step-by-step explanation:
If Alisa is 16 years old, that would mean that Barbara would be 8, since she is half of Alisa's age.
If we add 5 to Alisa's age, we get 21. To find the average of their ages, we add them all up, and divide by how many people there are (3).
16+8+21=45
45÷3=15
Hope this helps!
Age of Ailsa is 20 years. Then Candy's age will be 15 years.
What is the solution to the equation?In other words, the collection of all feasible values for the parameters that satisfy the specified mathematical equation is the convenient storage of the bunch of equations.
Ailsa is twice as old as Barbara. Ailsa is 5 years younger than Candy. The average age of Candy, Ailsa, and Barbara is 15.
Let 'x' be the age of Ailsa, 'y' be the age of Barbara, and 'z' be the age of Candy. Then the equations are given as,
x = 2y ...(1)
x - 5 = z ...(2)
(x + y + z) / 3 = 15 ...(3)
From equations (1), (2), and (3), then
x + x / 2 + x - 5 = 45
(5/2) x = 50
x = 20
Then the age Candy is calculated as,
z = 20 - 5
z = 15
Age of Ailsa is 20 years. Then Candy's age will be 15 years.

Jonah is attending a school orchestra concert. He sees his math teacher seated 6 meters ahead of him and his science teacher seated 7 meters to his right. How far apart are the two teachers? If necessary, round to the nearest tenth.
Answer:
42 meters
Step-by-step explanation:
if his math teacher is 6 meters ahead of him and his science teacher is 7 meters to the right of him than you multiply to get the area of distance from each other.
6 x 7 = 42
the teachers are 42 area meters away from each other
A triangle has sides with lengths of 31 feet, 72 feet, and 78 feet. Is it a right triangle?
yes
no
=========================================================
Explanation:
We have a triangle with these side lengths
a = 31b = 72c = 78The order of 'a' and b doesn't matter, but we must have c as the largest value. Usually a,b,c are in ascending order.
Plug those values into the formula for the pythagorean theorem. If we get the same thing on both sides, then we have a right triangle.
[tex]a^2 + b^2 = c^2\\\\31^2 + 72^2 = 78^2\\\\961+5184 = 6084\\\\6145 = 6084\\\\[/tex]
We have a false statement at the end, which means the original equation is false for those a,b,c values.
Therefore, we do not have a right triangle.
Instead, this triangle is acute since the [tex]a^2+b^2[/tex] side is larger than the [tex]c^2[/tex] side
---------------
Rules to have in your notebook or on a reference sheet:
[tex]\text{If }a^2 + b^2 = c^2 \text{ then it is a right triangle}\\\\\text{If }a^2 + b^2 > c^2 \text{ then the triangle is acute}\\\\\text{If }a^2 + b^2 < c^2 \text{ then the triangle is obtuse}\\\\[/tex]

Angles around a point
Grade 8
Answer:
x=45, y=45, z= 131
Step-by-step explanation:
x and y makes up a right angle (90). You can even;y split them in half, which is 45 degrees. Therefore, x= 45 and y also = 45.
Now that there are 2 right angles, that makes up 180. 180+49=229
A full rotation is 360, so you subtract that. 360-229=131
z=131.
Answer:
x = 41°y = 49°z = 131°Step-by-step explanation:
The relevant relations are ...
a straight angle measures 180°a right angle measures 90°vertical angles have the same measure__
The angle marked 49° and the one marked "y" are vertical angles, so have the same measure.
y = 49°
The angle marked "x" and the angle marked "y" together make up a right angle, so total 90°.
x + y = 90°
x + 49° = 90°
x = 41° . . . . . . . . . subtract 49°
The angle marked z and the one marked 49° together make up a straight angle, so total 180°. (They are a "linear pair.")
49° +z = 180°
z = 131° . . . . . . . subtract 49°
The measures of the marked angles are ...
x = 41°
y = 49°
z = 131°

And XZ=1/2XY
XZ be x
XY=YZ=2xNow
x+2x+2x=1075x=107x=21.4unitsXZ=21.4units
Answer:
XZ = 21.4 units
Step-by-step explanation:
If ΔXYZ is an isosceles triangle then XY = ZY
(the dashes on the line segments indicate they are of equal measure)
If XZ = ¹/₂XY then
⇒ 2XZ = XY = ZY
If the perimeter is 107 units:
⇒ Perimeter of ΔXYZ = XY + ZY + XZ
⇒ 107 = 2XZ + 2XZ + XZ
⇒ 107 = 5XZ
⇒ XZ = 107 ÷ 5

Answer:
p(x) = x⁴ -7x³ +59x² -343x +490
Step-by-step explanation:
Each root is the zero of a binomial factor. That is, for root x = a, the polynomial has a factor (x -a). Complex roots come in conjugate pairs, so if there is a root 7i, there is also a root -7i.
__
The given roots mean the polynomial can be written in factored form as ...
p(x) = (x -2)(x -5)(x -7i)(x -(-7i))
We can combine multiply these factors together to simplify the polynomial.
p(x) = (x² -7x +10)(x² +49)
p(x) = x⁴ -7x³ +59x² -343x +490

Combining the conjugate complex roots uses the special form for the factoring of the difference of squares.
a² -b² = (a -b)(a +b)
