Step-by-step explanation:

Given

New function: [tex]y = 3 \cos(10 (x -\pi))[/tex]

We can assume the parent function to be:

[tex]y = \cos (x)[/tex]

The new function can be represented as:

[tex]y = A*\cos((\frac{2\pi}{B})(x-c))[/tex]

Where

A = Vertical stretch factor

B = Period

C = Right shift

By comparison:

[tex]y = A*\cos((\frac{2\pi}{B})(x-c))[/tex] to [tex]y = 3 \cos(10 (x -\pi))[/tex]

[tex]A = 3[/tex]

[tex]c = \pi[/tex]

[tex]\frac{2\pi}{B} = 10[/tex]

Solve for B

[tex]B = \frac{2\pi}{10}[/tex]

[tex]B = \frac{\pi}{5}[/tex]

Using the calculated values of [tex]A,\ B\ and\ c.[/tex] This implies that, the following transformations occur on the parent function:

Answer:

y=-6/5x-2

Step-by-step explanation:

We are given points (5,-8) and (-5,4)

Slope = m = (y₂-y₁)/(x₂-x₁) = (-8-4/(5-(-5)) = -12/10 = -6/5

Y-intercept = b = (0,-2)

Final equation: y=-6/5x-2

Answer:

y=-6/5x-2

Step-by-step explanation:

y=mx+b

Its sloping downwards, so a negative slope.

two points: (-5,4) and (5,-8)

---------------------------------------------

so first find the slope.

y2-y1 / x2-x1  <= formula

so: -8-(4) / 5-(-5)

which becomes => -12/ 10

which is 6/5 the slope is 6/5

------------------------------------------

plug this into y=mx+b, where m is the slope

so: y=6/5x+b

------------------------------------------

obviously b is the y intercept, where the line meets y

the y intercept is -2

sooooooo final answer is

----------------------------------

y=6.5x+(-2)

-----------------------------------

Negative slope, so becomes y=6/5x-2

a. 10x - 2

Step-by-step explanation:

4x - 2 +6x ( collect like terms )

4x +6x - 2

10x - 2

Answer:

the zero of a function is what value you can plug in and get 0 as the answer.

having a multiplicity of 3 means that the zero is there 3 times so if your zero is 2 with multiplicity 3 then (x-2)^3 is what it looks like

x^2-16x+ __

what do we do to find the blank?

We divide 16 by 2 to get 8

then we take the square of 8

which is 64

so this would be  x^2-16x+ 64 = 64

REMEMBER 64 goes to BOTH sides of equation

Step-by-step explanation:

Given

[tex]9 + x >-11[/tex]

Solving (a): The solution

[tex]9 + x >-11[/tex]

Collect like terms

[tex]x >-11-9[/tex]

[tex]x >-20[/tex]

Solving (b): Illustration on a number line

Where the solution starts

It starts on -20

Open or closed circle

An open circle; because the solution shows greater than

The direction

Greater than means that, the solution is towards the right.

Hence, the direction is right

Answer:

w = 18

Step-by-step explanation:

Given

[tex]\frac{1}{3}[/tex] (w + 18) = 12 ← distribute parenthesis on left side

[tex]\frac{1}{3}[/tex] w + 6 = 12 ( subtract 6 from both sides )

[tex]\frac{1}{3}[/tex] w = 6 ( multiply both sides by 3 to clear the fraction )

w = 18

Answer:  

(-1/2,1/2)

Step-by-step explanation:

Normally for sinx amplitude is 2 (1 +1). In the case when it is half sine amplitude is halved, therefore 0.5 +0.5 = 1 Paramers alpha = 2x does not matter because it only stretches the graph horizontally.

Answer:

arc PST = 254°

Step-by-step explanation:

arc QPT = 180° because it is a diameter

arc PQ = 74°

arc PT = 180° - 74° = 106°

arc PST = 360° - 106° = 254°

Answer: B

Step-by-step explanation:

Given:

Each right triangular tiles has the leg measures of 5.2 cm and 6 cm.

There are 150 tiles in the mosaic.

To find:

The area of the mosaic.

Solution:

We know that, the area of a triangle is:

[tex]A=\dfrac{1}{2}\times Base\times height[/tex]

So, the area of Each right triangular tile is:

[tex]A=\dfrac{1}{2}\times 5.2\times 6[/tex]

[tex]A=\dfrac{1}{2}\times 31.2[/tex]

[tex]A=15.6[/tex]

There are 150 tiles in the mosaic. So, the area of the mosaic is:

[tex]Area=15.6\times 150[/tex]

[tex]Area=2340[/tex]

Therefore, the total area of the mosaic is 2340 cm ².
