Because this is a second degree equation you will have 2 solutions. When you take the square root of a number you have to account for both the positive and negative roots. Since the square root of 289 is 17 then your solutions are +17 and -17.
Answer:
Step-by-step explanation:
The radius it .5 of the diameter so in this case the radius is 11. The formula for area is pi*r^2= pi*11^2=pi*121=380.13
Commutative Property of Addition
Answer:
No you do not.
This is because we can use Pythagoras Theorem to show that our location sits outside the 15 mile radius of the cell tower.
To work is out you would write the equation

Then to work out the Hypotheses you would

Which proves that the location is outside of the 15 Mile radius of the cell tower.
A geometric series like

Converges if and only if
. If this is the case, the sum equals

So, in your case, you have convergence if and only if

And if this is the case, the sum equals
