Product is multiplying. when you multiply a letter with a number you don't put any symbols so it would be 8c
Step-by-step explanation:
Hello there, because you did not attached the photo or the information of the diameter of the circle, so I will solve this type of question under a general form
Let's assume d is the diameter of the circle
=> the perimeter of the circle is: dπ
=> the perimeter of the half arc of a circle
= 1/2 perimeter of the circle
= 1/2dπ
Hence, the perimeter of the stage shaped like a semi-circle:
= the perimeter of the half arc of a circle + the diameter
= 1/2dπ + d
= 3/2dπ
Just substitute d into the above expression, you will find out the answer.
Hope it will find you well.
Answer:
the answer would be 0.
Step-by-step explanation:
the line would go straight down the middle.
Answer: 
Step-by-step explanation:
The equation of the line in Slope-Intercept form is:

Where "m" is the slope and "b" is the y-intercept.
We can calculate the slope of the line with this formula:

Given these points:

We can identify that:

Then, the slope is:

Now we have to substitute the slope and one of the points into
and solve for "b":
Then, the equation of this line is:

Answer:
-1.8
Step-by-step explanation:
