A directed line segment on a gridded map shows the path of a hot air balloon from 1(0,0) to B(8,4). Each grid unit represents 1
aivan3 [116]

Answer:

Step-by-step explanation:

There is  a point V with ration 6 to 2, therefore we must find the coordinates of point V and the distance from A to V

<u>According to the graph</u>

c^{2}=x^{2}+y^{2}\\c^{2}=8^{2}+4^{2}\\c=\sqrt{64+16}=8.9.4\\sin\alpha =\frac{4}{8.94}

α≅27°

V=2*8.94/6 (ratio 6:2)

V=2.98mile

sin27=\frac{y}{2.98}\\y=sin27*2.98=1.35\\cos27=\frac{x}{2.98}\\x=cos27*2.98=2.65

coordinates of V = (2,65;1.35)

Distance from A to V

d_{AV}=2.98 miles

finally

Mary's mistake is to take the 6 to 2 ratio as the distance traveled from the globe only in the x direction

How much money must be deposited now in an
Liono4ka [1.6K]

Answer:

\$487.48

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=10\ years\\ A=\$1,000\\ r=7.25\%=7.25/100=0.0725\\n=4  

substitute in the formula above

1,000=P(1+\frac{0.0725}{4})^{4*10}  

1,000=P(\frac{4.0725}{4})^{40}

P=1,000/(\frac{4.0725}{4})^{40}

P=\$487.48
