shakira invests $500000 at 5% compound intwerest per annum . calculate how many years it takes for the value to double in value?
Kay [80]

Answer:

t=14.2\ years    

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=?\ years\\ P=\$500,000\\ r=0.05\\n=1\\ A=\$1,000,000  

substitute in the formula above  and solve for t

1,000,000=500,000(1+\frac{0.05}{1})^{(1)t}

2=(1.05})^{t}  

Apply log both sides

log(2)=log[(1.05})^{t}]  

log(2)=(t)log(1.05)  

t=log(2)/log(1.05)  

t=14.2\ years

A rectangle on a coordinate plane is translated 5 units up and 3 units to the left. Which rule describes the translation?
Serggg [28]

Answer:

The last one (x,y)->(x+3,y+5)

Step-by-step explanation:

Whenever you move the x coordinate it’s the opposite, for example translated 3 units the the left is +3 and translated 3 units to the right is -3.

Whenever you move the y coordinate it’s normal so up 5 units means +5 and down means -5.
