QUESTION POSTED AT 18/01/2020 - 06:37 AM

The formula A=P(1+r)^2 gives the amount A in dollars that P dollars will grow to in 2 years at interest rate R (where r is given as a decimal), using compound interest. What interest rate will cause $ 5000 to grow to $ 5304.50 in 2​ years?

P=presne amount=5000
A=furutre amount which you want to be 5304.50

solve for r

5304.50=5000(1+r)^2
divide both sides by 5000
1.0609=(1+r)^2
sqrt both sides (remember to get positive and negative roots)
+/-1.03=1+r
minus 1 both sides
+/-1.03-1=r

+1.03-1=r=0.03=3%
-1.03-1=r=-2.03=false, no negative percents

answer is 3%

What is 2.16 repeated as a decimal

Ok, so what we want to do here is first remove the repeating decimal.

x=2.16 repeating
10x=21.6 repeating
100x=216.6 repeating

Subtract 10x=21.6 repeating from 100x=216.6 repeating. This will get rid of the repeating numbers.

100x=216.6 repeating
-10x=21.6 repeating
__________________
90x=195

Divide both sides by 90.

x=195/90

Now you can simplify that into 13/6.

Use the definition of a polygon inscribed in a circle to help you develop a definition for a polygon inscribed in a sphere.

For a polygon inscribed in a circle, the circle passes through all of the vertices of the polygon. Using this idea, a polyhedron (a 3-D polygon) inscribed in a sphere can be described in a similar way. The sphere also touches all of the vertices of the polyhedron, except this is done in 3 dimensions, not limited to just 2 dimension.

The total cost of a belt and a jacket was $82.78 if the price of the belt was $0.86 less than the jacket what was the price of the belt express your answer as a simplified fraction or a decimal rounded to the 2nd Place

I made it into an equation (j-0.86)+j=82.78 first u have to find the price of the jacket and the add it in the equation so 82.78-0.82 and what ever u do to one side u do to the other so -0.82+0.82 they which equals 0 and 82.78+0.82=83.64 so now the equation is j + j=83.64, j + j is 2j=83.64 so 83.64 divided by 2 equals 41.82 and 2j divided by 2 equals j so the jacket cost 41.82 but ur looking for the cost of the belt so (41.82-0.86)+41.82=82.78, 41.82-0.86=40.96, so the BELT EQUALS 40.96 and if u add 41.82 to that u will get 82.78
