this is how i would solve this problem. I hope it's helpful
Answer:
Make sure you are using a perfect circle. This method won't work with ellipses, ovals or anything but a real circle. A circle is defined as all the points on a plane that are an equal distance from a single center point. The lids of jars are good household objects to use for this exercise.You should be able to calculate pi roughly because in order to get exact results of pi, you will need to ...
Measure the circumference of a circle as accurately as you can. The circumference is the length that goes around the entire edge of the circle. Since the circumference is round, it can be difficult to measure (that's why pi is so important). Lay a string over the circle as closely as you can. Mark the string off where it circles back around, and then measure the string length with a ruler.
Measure the diameter of the circle. The diameter runs from one side of the circle to the other through the circle's center point.
Use the formula. The circumference of a circle is found with the formula C= π*d = 2*π*r. Thus pi equals a circle's circumference divided by its diameter. Plug your numbers into a calculator: the result should be roughly 3.14.[3] X Research source
Repeat this process with several different circles, and then average the results.

Answer:
y - 5 = 5(x - 1)
Step-by-step explanation:
Two points on the graph are (1, 5) and (7, 35). Going from the first to the second, we see x (the 'run') increasing by 6 and y (the 'rise') increasing by 30. Hence the slope of this line is m = rise / run = 30/6, or 5.
Using the point-slope equation, we get
y - 5 = 5(x - 1)
Is part of the problem missing? There should be another set of numbers after -5+2n-11 so “n” can be isolated
Answer:
Step-by-step explanation:
We need three rules. Raising a power to a power. Raising a product to a power. Raising a number to a negative exponent.
Rule 1:
To raise a power to a power, multiply powers.
Rule 2:
To raise a product to a power, raise every factor of the product to the power.
Rule 3:
To raise a number to a negative power, follow this formula.
Your problem.
You have a product raised to a power, so raise each factor to the power.
Now raise each power to a power by multiplying exponents.
Now we follow the rule of a negative exponent.
