Answer:
x = 120/17
Step-by-step explanation:
In this arrangement of right triangles, each is similar to any other. Then the ratio (long side)/(hypotenuse) is the same for all.
long side/hypotenuse = BD/BA = CB/CA
x/8 = 15/17
x = 8(15/17)
x = 120/17

Triangle XYZ is rotated to create the image triangle X'Y'Z'.
On a coordinate plane, 2 triangles are shown. The first triangle has points X (negative 2, 2), Y (1, 2), Z (0, 4). The second triangle has points X prime (2, negative 2), Y prime (negative 1, negative 1), Z prime (0, negative 4).
Which rules could describe the rotation? Select two options.
R0, 90°
R0, 180°
R0, 270°
(x, y) → (–y, x)
(x, y) → (–x, –y)

Answer:
R0, 180°
(x, y) → (–x, –y)
Step-by-step explanation:
Knowing that:
The coordinates of ΔXYZ is x '(-2, 2), Y(1, 2), Z(0, 4)
The coordinates of ΔX'Y'Z' is x'(2, -2), Y'(-1, -1), Z'(0, -4)
Coordinates of the preimage = (x, y)
Coordinates of the image = (-x, -y)
transformation by rotation 180° about the origin.

Which of the following cosine functions has a period of 3Pi
Answers
Answer:
C
Step-by-step explanation:
Hello!
In the equation y=a cos bx, we can learn alot about the cosine graph.
a is the amplitude, or how 'long' the cosine graph is.
b is the period, which is how 'wide' one cycle of a cosine period can be. The higher the period, the wider the cycle is.
In this equation, we are focused on finding the period; so any choices that contain amplitude is not a correct answer choice for this problem, which leaves out B and C.
To find the period, we can plug b into [tex]\frac{2\pi }{b}[/tex] , which in a way converts the b value to a period.
For B) y= cos3x
[tex]\frac{2\pi }{3}[/tex]= it does not equal 3 [tex]\pi[/tex]
For C) y=cos [tex]\frac{2}{3}[/tex]x
[tex]\frac{2\pi }{\frac{2}{3}}[/tex]= equals 3 [tex]\pi[/tex] when simplified
Since C equals 3 [tex]\pi[/tex] as a period, C is the only logical answer.

Simplify these expressions:

b) 6x - 2x + 8y - 6y
Answers
Answer:
a)8x+6y
b)4x+2y
Step-by-step explanation:
a)5x+3x+2y+4y
5x+3x=8x
2y+4y=6y
=8x+6y
b)6x-2x+8y-6y
6x-2x=4x
8y-6y=2y
=4x+2y
Answer:
a) x = -0.75y
b) x = -0.5y
Step-by-step explanation:
Simplifying
5x + 3x + 2y + 4y = 0
Combine like terms: 5x + 3x = 8x
8x + 2y + 4y = 0
Combine like terms: 2y + 4y = 6y
8x + 6y = 0
Solving
8x + 6y = 0
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-6y' to each side of the equation.
8x + 6y + -6y = 0 + -6y
Combine like terms: 6y + -6y = 0
8x + 0 = 0 + -6y
8x = 0 + -6y
Remove the zero:
8x = -6y
Divide each side by '8'.
x = -0.75y
Simplifying
x = -0.75y
Simplifying
6x + -2x + 8y + -6y = 0
Combine like terms: 6x + -2x = 4x
4x + 8y + -6y = 0
Combine like terms: 8y + -6y = 2y
4x + 2y = 0
Solving
4x + 2y = 0
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-2y' to each side of the equation.
4x + 2y + -2y = 0 + -2y
Combine like terms: 2y + -2y = 0
4x + 0 = 0 + -2y
4x = 0 + -2y
Remove the zero:
4x = -2y
Divide each side by '4'.
x = -0.5y
Simplifying
x = -0.5y

The difference of two supplemtary angles is 58 degrees. Find the measures of the angles
Answers
Answer:
The measure of the angles are 61° and 119°
Step-by-step explanation:
Let the first angle = x°
let the second angle = y°
The sum of two supplementary angles = 180°
x° + y° = 180° ----- equation (1)
based on the given question; "the difference of two supplementary angles is 58 degrees."
x° - y° = 58° ------- equation (2)
from equation (2), x° = 58° + y°
Substitute the value of x into equation (1)
(58° + y°) + y° = 180°
58 + 2y = 180
2y = 180 -58
2y = 122
y = 122 / 2
y = 61°
The second angle is given by;
x° = 58° + y°
x = 58° + 61°
x = 119°
Thus, the measure of the angles are 61° and 119°

Find the first term of a G.P. whose fifth term is 243 and the

Answers
Answer:
first term = 3
Step-by-step explanation:
The n th term of a GP is
[tex]a_{n}[/tex] = a₁[tex](r)^{n-1}[/tex]
where a₁ is the first term and r the common ratio
Here r = 3 and a₅ = 243 , thus
a₁ × [tex]3^{4}[/tex] = 243
a₁ × 81 = 243 ( divide both sides by 81 )
a₁ = 3
