12 over 15
all of them but that one simplify to 2 over 3
The question can be solved using formula <span>an = a1(1 + r)^n where n is the number of year, r is the interest rate and a is the initial amount. The value of the variable would be:
a= initial amount = $15,000
r= interest= 10%= 0.1
n= number of year = 16
The calculation would be:
</span><span>an = a1(1 + r)n
</span><span>a16 = $15,000(1 + 0.1)^16
</span>a16 = $15,000(1 .1)^16
a16 = $15,000(4.59497)
<span>a16= $68,924.59</span>
<span>sin (a - b) = sinacosb - sinbcosa
1) sin345° = sin (360 - 15) = sin360cos15 - sin15cos360= 0-sin15 *1=
</span>sin345° = - sin15,
2) cos(11π) /12= - cos pi / 12 = cos ( - 4pi/12 +3pi/12)= cos (- pi/3 + pi/4) =
cos (-pi/3) cos pi/4) + sin (-pi/3) sin( pi/4) = sqrt6 /4 - sqrt2/ 4
