Answer:
The arc length of the semicircle is 
or 
Step-by-step explanation:
The complete question in the attached figure
we know that
The circumference of a semicircle is given by the formula
where
D is the diameter of the semicircle
we have
substitute
----> exact value
Assume
----> approximate value
therefore
The arc length of the semicircle is or
20/100 in simplest form is 1/5
Using addition
x-y+1/2x+y=1+5
x+1/2x+0y=6
3/2x=6
3x=12
x=4
Using the value of x
x-y=1
4-y=1
y=3
With x as 4 and y as 3, their product is 12
And can be written as (4,3)
Answer:
Is there a picture, if not how many are in total and how many of each color
Option third "words per minute, because the independent quantity is the minutes" is the correct choice.
<h3>What is the rate of change?</h3>
It is defined as the change in values of a dependent variable with respect to the independent variables.
We have a statement:
Which of the following is the most appropriate unit to describe the rate at which a person reads?
As we know the rate of change is the ratio of change in y to change in x.
y is the dependent quantity and x is the independent quantity.
Rate of change = change in y/change in x
Rate at which a person reads = words/minute
Word is the dependent quantity and minute is the independent quantity.
Thus, option third "words per minute, because the independent quantity is the minutes" is the correct choice.
