Isolate the w. Note the equal sign. What you do to one side, you do to the other.

Add 3π to both sides

- 3π (+3π) + w = 2π (+3π)

w = 2π + (3π)

w = 5π

w = 5π is your answer

hope this helps

If the endpoints of the diameter of a circle are (8, 6) and (2,0), what is the standard form equation of the circle?
zvonat [6]

Answer:

It is C.

Step-by-step explanation:

The centre of the circle is at the midpoint of The diameter = (8+2)/2, (6+0)/2 = (5,3) so the left side of the equation is (x-5)^2+(Y-3)^2. Now we need to work out the radius:

The diameter = square root(8-2)^2+6^2) = square root of 72 = 6sqrt2.

So the radius = 3sqrt2 and r^2=18.

Nesterboy [21]

Answer:

Jan wants to save a $2000 gift from her grandparents, and add $50 per month as emergency funds.

Bank A pays a fixed rate of interest, and Bank B pays a variable rate, but both rates are currently the same.

Based on her own needs, I would advice Jan to look out or few things like -

When you are expecting to save more money, you should prioritize about the interest rates as they will have an effect on your accounts and balance.

You should also look for the chargeable fee and services that are applied on that account as these make a big difference on the account when you have little balance. The type of interest (fixed or variable) does not matter that much. When you have more money in account then these fee looks negligible.
