kondaur [170]

The perimeter of each is the sum of the lengths of its sides.

Triangle Perimeter = 16 + 4x-3 +3x = 7x+13

$1000 invested with compound interest at a rate of 15% per year for 9 years.
ivolga24 [154]

Answer:

The Final Investment Value is \$3,517.88  

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=9\ years\\ P=\$1,000\\ r=0.15\\n=1  

substitute in the formula above  

A=1,000(1+\frac{0.15}{1})^{1*9}  

A=\$3,517.88

Let's give some distances
100 up 100 flat 100 down meters
then return 100 up 100 flat 100 down


time required (distance/rate = time ) 200/100 + 200/120 + 200 / 150 = 5 hr

distance 600


distance / time = average speed = 600/5 = 120 m/s
