For this case, since the variation is direct then we have a relation of the form:
Where,
k: proportionality constant
To find k we substitute the following data:
y = 16 when x = 8
We have then:
Clearing the value of k we have:
Then, the equation is:
Substituting the value of x = 16 we have:
Answer:
The value of y for x = 16 is:
Answer:
yes
Step-by-step explanation:
The distance formula as shown below:
Recall that the perimeter of a polygon is the sum of the lengths of each side of the polygon.
Since a regular octagon has 8 sides of equal length, and the stop sign is a regular octagon with a side length of 12 in, then its perimeter is:
Simplifying the above result we get:
Answer:
