Circumference= 2×pi×R
Area= pi× R^2
Since Diameter=2 cm ---> Radius is 2× diameter , so R=4 cm

Circumference=2×3.14×4= 25.12 cm
area=3.14× (4)^2= 50.24 cm^2

In two or more complete sentences, describe the transformation(s) that take place on the parent function, f(x)=log(x), to achiev
matrenka [14]
Transforming f(x) = log(x) to f(x) = log (2x) gives the effect of squashing the graph horizontally (by halving the x-coordinate)

Then from f(x) = log(2x) to f(x) = log (-2x) is reflecting on the y-axis

Then from log(-2x) to log(-2x-4) is to translate by 4 units to the right

Finally from log(-2x-4) to log(-2x-4)+5 is translating the graph up by 5 units

What is the slope of all lines perpendicular to the line y=(2/3)x+7
Alexandra [31]

Answer:

The slope is -3/2

Step-by-step explanation:

<u>A line that is perpendicular to another has the slope that has the sign reversed and is the reciprocal. </u>

Example:  Find the line perpendicular to y = 3x

First, you flip the sign which makes 3 into -3

Next, you make the reciprocal which makes -3 into <u>-1/3 </u>

Problem:  Find the line perpendicular to y = (2/3)x + 7

First, you flip the sign which makes 2/3 into -2/3

Next, you make the reciprocal which makes -2/3 into <u>-3/2</u>

Answer:  The slope is -3/2
