Answer:

arc ≈ 5.5 units

Step-by-step explanation:

The arc of the circle is calculated as

arc = circumference of circle × fraction of circle

     = 2πr × \frac{\frac{\pi }{2} }{2\pi } ( r is the radius )

    = 2π × 3.5 × \frac{1}{4}

    = \frac{7\pi }{4}

    ≈ 5.5 ( to the nearest tenth )

What is the equation of the line that is perpendicular to y = one-fifth x + 4 and that passes through (5,–4)?
Brilliant_brown [7]

Answer:

y = -5x + 21

Step-by-step explanation:

perpendicular lines have slopes that are negative reciprocals.

The given line has a slope of 1/5, so the perpendicular line will have a slope of -5.

y = -5x + B

-4 = -5(5) + B

B = -4 + 25 = 21

y = -5x + 21

The graph of the parent function y = x cubed is horizontally stretched by a factor of One-fifth and reflected over the y-axis. W
sasho [114]

Answer: OPTION D.

Step-by-step explanation:

Below are some transformations for a function f(x):

If -f(x), then the function is reflected over the x-axis.

If f(-x), then the function is reflected over the y-axis.

If f(bx)  and b>1, then the function is horizontally compressed.

If  f(bx)  and 0 < b, then the function is horizontally stretched.

In this case you know that the parent function is:

y=x^3

According to the information given in the exercise, the parent function IS horizontally stretched by a factor of \frac{1}{5} and it is also reflected over the y-axis.

Therefore, based on the transformations explained before, you can notice that the transformation is:

f(-bx)

Where 0 < b

Therefore, the equation of the transformed function is:

y=(-\frac{1}{5}x)^ 3
