Answer:

d=\sqrt{26}\approx5.0990

Step-by-step explanation:

To find the distance between any two points, we can use the distance formula.

The distance formula is:

d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}

Let (2,8) be x₁ and y₁ and let (7,7) be x₂ and y₂. Thus:

d=\sqrt{(7-2)^2+(7-8)^2}

Simplify:

d=\sqrt{5^2+(-1)^2}

Square:

d=\sqrt{25+1}

Add:

d=\sqrt{26}\approx5.0990

And that's our answer :)

Consider a $100 investment earning 12% compounded quarterly. how long will it take to triple your money? round your answer to th
ANTONII [103]
Summarizing the question,
Principle(P)=$100
Rate (r)=12%=0.12
Amount (A)=3×P=$300
Time=t=?
n=no of times the interest is compouned per year=4
Then,
A=P{(1+r/n)}^(n×t)
or,300=100×{1+0.12/4}^(4×t)
or,300/100=(1+0.03)^(4×t)
or,3=1.03^(4×t)
Taking log on both sides,
log3=log[(1.03)^(4×t)]
or,log3= (4×t)×log(1.03)
or,4t=log3/log(1.03)
or,t=log3/[4×log(1.03)]
or, t=9.29175...
t=9.3 years ANS!!!

Sergeeva-Olga [200]

Answer:

The interest is equal to \$13$13

we know that

The compound interest formula is equal to

A=P(1+\frac{r}{n})^{nt}A=P(1+

n

r

)

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

\begin{gathered}t=3\ years\\ P=\$80\\ r=0.05\\n=1\end{gathered}

t=3 years

P=$80

r=0.05

n=1

substitute in the formula above

A=\$80(1+\frac{0.05}{1})^{3}=\$92.61A=$80(1+

1

0.05

)

3

=$92.61

Find the interest

I=A-P=\$92.61-\$80=\$12.61I=A−P=$92.61−$80=$12.61

Round to the nearest whole dollar

\$12.61=\$13$12.61=$13
