Answer:

The formula to calculate APY is (1 + (i/n))^n - 1

where i is the interest rate and n is the number of compounding periods.

Monthly APY = (1 +(0.055/12)^12 -1

APY = 0.0564 = 5.64%

Quarterly APY =  (1 +(0.055/4)^4 -1

APY = 0.0561 = 5.61%

Difference = 5.64 - 5.61 = 0.03% more when compounded monthly.

The APY is more when compounded monthly, because there are more compound periods.

tekilochka [14]

Answer:

To first find the volume of the sphere, you need to first find the radius. To find this, you take the circumference of 29.5 inches and divide by pi to get the diameter.

Then divide the diameter by 2 to get the radius.

So we get a radius of about 4.70.

Then we use the formula for the volume of a sphere which is

Substituting in R for 4.69........, we get

Rounded to the nearest inch, we get 434 inches cubed.

By the Triangle Inequality Theorem, if two sides of a triangle have lengths of 6 and 13, what are the possible lengths of the th
melamori03 [73]
The <span>Triangle Inequality Theorem establishes that the length of the triangle is shorter than the sum of the two lenghts of the others two sides. Then, you have:

 a=6   (the lenght of a side of the triangle).
 b=13   (t</span>he lenght of a side of the triangle).<span>
 c=x    (the length of the third side).

 Therefore:

 c<a+b
 c<6+13
 c<19

 The lenght of the third side is:

 (13-6)<c<19
 7<c<9</span>
