If a person walks 1/3 a mile in each 1/2 hour, how far does he walk in 1 hour.
serg [7]

Distance travelled in 30 minutes = 1/3 miles

Distance travelled in 1 minute = 1/(3 × 30)

Distance travelled in 60 minutes = (1 × 60)/(3 × 30)

= 2/3 miles

Create an exponential to describe $100 at 2% interest compounded annually for x years
zysi [14]

Answer:

A=100(1.02)^{x}                  

Step-by-step explanation:

we know that    

The compound interest formula is equal to  

A=P(1+\frac{r}{n})^{nt}  

where  

A is the Final Investment Value  

P is the Principal amount of money to be invested  

r is the rate of interest  in decimal

t is Number of Time Periods  

n is the number of times interest is compounded per year

in this problem we have  

t=x\ years\\ P=\$100\\ r=2\%=2/100=0.02\\n=1  

substitute in the formula above

A=100(1+\frac{0.02}{1})^{1*x}  

A=100(1.02)^{x}
