Compounded Quarterly
We will calculate $100 growing to $200
Years = log(total/principal) / n*log(1 + rate/n)
For quarterly compounding n = 4
Years = log(200 / 100) / 4 * log (1 + .09/4)
Years = log(2) / 4 * log ( <span><span><span>1.0225 </span> )</span>
</span>Years = 0.30102999566 / (4 * 0.0096633166794)
Years = 0.30102999566 / <span> <span> <span> 0.0386532667 </span> </span> </span>
Years = <span> <span> <span> 7.7879574318 </span> </span> </span>

Compounded Continuously
We will calculate $100 growing to $200
Years = natural log (total/principal) / rate
Years = natural log (200 / 100) / .09
Years = natural log (2) / .09
Years = 0.69314718056 / .09
Years = <span> <span> <span> 7.7016353396 </span> </span> </span>

A pyramid has a regular hexagonal base with side links of four and a slant height of six. Find the total area of the pyramid
vova2212 [387]

Area of the Base = 6 * side^2 / 4 * tan (180/6)

Area of the Base = 6 * 16 / 4 * 0.57735

Area of the Base = 96 / 2.3094

Area of the Base = 41.5692387633


Area of 1 Face = 2 * 6 = 12

Area of 6 Faces = 72


Total Area = 41.5692387633 + 72

Total Area = 113.5692387633

Graph the function.
disa [49]

Answer:

Line passing through (0,2),(1,-21).

Step-by-step explanation:

y=-23x+2\\at\ y\ axis\ x=0\\y=-23\times0+2\\y=2

hence this line passes through (0,2).

When x=1

y=-23\times1+2\\y=-21

Hence this line passes through (1,-21).

Graph is attached.
