Answer:

0.054

Step-by-step explanation:

Using the compound formula A=P(1+r/n)^nt we can plug in the numbers we know. A being the total, P the initial amount, n is the number of compounds in a year, and t is the number of years passing. So 10300= 4900(1+ r/2)^2(14). We have to isolate r in order to find the rate. We can divide both sides by 4900, giving us 103/49= (1+ r/2)^28. Then we take the 28 square root from both sides. 1.02689= 1 + r/2. Subtract 1 from both sides. 0.02689= r/2. Then multiply both sides by two. r= 0.054.

Answer:

-1 1/5

Step-by-step explanation:

<em>Change the whole number 4 to an improper fraction</em>

-4 4/5 ÷ 4/1 = -4 4/5 ÷ 4/1

<em>Reciprocal the 4/1 will become 1/4 then go to multiplication</em>

-4 4/5 ÷ 4/1 = -4 4/5 × 1/4

<em>Change to improper fraction the -4 4/5</em>

-4 4/5 ÷ 4/1 = -24/5 × 1/4

<em>Then simply multiply the two numerators and the two denominators</em>

-4 4/5 ÷ 4/1 = -24/20

<em>Finally, Simplify it to get the answer</em>

-4 4/5 ÷ 4/1 = -1 1/5
