Answer:

f(x) = x^3

Step-by-step explanation:

f(x) = (1/4x )^3

y = f(Cx)

y = x^3 and C = 1/4

This function is stretched in the x direction

The parent function is x^3

Item 4 Find the perimeter of the window. Round your answer to the nearest tenth. 90 cm

Answer:

Step-by-step explanation:

item 4 Find the perimeter of the window. Round your answer to the nearest tenth. 90 cm

You did not state the diameter or radius of the window

so, i will use 90cm as the diameter of the window

First, I'd calculate the half circumference of the window.

The formula for circumference is $c = 2\pi r$ ,

Half of it would just be $c/2 = r\pi$

Since our diameter is 90 cm, our radius is 45 cm.

Circumference =

$=45\pi \\= 141.37 cm$

circumference is also the same with perimeter

<h3>so, the answer is 141.37cm</h3><h3>to nearest tenth = 141.4cm</h3>

Answer:

$\large\boxed{1.\ the\ slope\ is\ \dfrac{1}{4}}\\\boxed{2.\ y=3x-5}\\\boxed{3.\ (3, 6)}$

Step-by-step explanation:

$\text{Let}\ k:y=m_1x+b_1\ \text{and}\ l:y=m_2x+b_2.\\\\l\ \perp\ k\iff m_1m_2=-1\to m_2=-\dfrac{1}{m_2}\\\\l\ \parallel\ k\iff m_1=m_2\\\\m-slope\\b-y-intercept\to(0,\ b)\\\\1.\\\\y=-4x+1\to m_1=-4\\\\m_2=-\dfrac{1}{-4}=\dfrac{1}{4}$

$2.\\y=3x+2\to m_1=3\\\\m_2=3,\ b=-5\\\\y=3x-5$

$\text{Calculate}\ a\ \text{and}\ b:\\\\a=\dfrac{6-(-9)}{5}=\dfrac{15}{5}=3\\\\b=\dfrac{8-(-2)}{5}=\dfrac{10}{5}=2\\\\\text{Calculate the coordinates of a point:}\\\\x=-9+4a\to x=-9+4(3)=-9+12=3\\\\y=-2+4b\to y=-2+4(2)=-2+8=6$
