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
Answer:
(f ￮ g)(x) = 
Step-by-step explanation:
Substitute x = g(x) into f(x) , that is
(f ￮ g)(x)
= f(g(x))
= f(x + 1)
=
Answer:
As this triangle is being transformed by rotation, the angles will stay same as well as the sides and other details, if you are doing this on a coordinate plane, then the points of the triangle would be changed and nothing else
If my answer helped, please mark me as the brainliest!!
Thank You!
Answer:
Multiply both numbers, sorry i can't see the numbers properly or i'd have answer the question myself.
Step-by-step explanation:
