is the expression that includes an exponent and has a value of 8
<em><u>Solution:</u></em>
Given that, Use the number 8, 6, and 2 and one operation to write an expression that includes an exponent and has a value of 8
We have to use each number only once
Given numbers are 8, 6, 2
Our expression should include exponent and the result should be 8
Among 6 and 2 we can use 2 for exponent
Raise 2 to power of 1
<em><u>The expression becomes:</u></em>

Here we have used one operation, that is addition
Verifying the expression

Thus the required expression is found
Answer:
hello the function graph is turned 90 degree like clock way.
Answer:
PerimeterFigure= pi*DIameter/2= 1.5*pi ft.
Step-by-step explanation:
The perimeter is the length of the figure, since we are dealing with an semi-circle, we can use the perimeter equation for a full circle and divide it by half.
Perimeter= 2pi*R= pi*Diameter.
Since Our figure is a semi circle, as we say earlier, we now will divide the above result by half.
PerimeterFigure= pi*DIameter/2= 1.5*pi ft.
