Y = cos(x) sqrt(3)/2 = cos(30º) dy = -sin(x)*dx dy = -sin(30º)*(pi/180) = (1/2)*(pi/180) y + dy = cos(x) - sin(x)dx y + dy = sqrt(3)/2 - (1/2)*(pi/180) = 0.8573

the cost of running an appliance varies jointly as the number of watts used, the hours of operation, and the cost per kilo-watt
zhuklara [117]
Suppose:
C=cost
c=cost per kilo-watt hour
w=number of watts
h=number of hours
thus
C=kwhc
where:
k=constant of proportionality:
k=C/(whc)
but
C=15 when w=6000, h=10/60=1/6 hours, c=7.5 cents per kw/h
thus
k=15/(6000*1/6*7.5)
k=0.002
thus:
C=0.002(whc)
hence:
when 
h=70*2=140=140/6=70/3 hours the cost will be:
C=0.002(6000*70/3*7.5)
C=2100 cents
C=$21
