The final cost of the tablet is c(t) = 1.08p = 1.08(0.85t) = 0.918t
Required function is c(t) = 0.918t
Answer:
It is a little bit trivial:
As we know:
Energy sink: is anything that uses energy.
Energy source: is anything that produces energy.
How the caol deposits can be energy sinks? well, you want to extract the coal from those deposits, and to do it, you need to "use energy" (the type of energy can depend on the extraction method, for example, if you use a pickaxe to extract the coal, you are using mechanical energy)
These coals are potential energy sources because coal is an energy source, potential means that, given some circumstances, something can transform into other things.
So potential energy source in this situation means that those coal deposits can be potential energy when we extract the coal and use it as an energy source.
Answer:
she would pay 97.2 in tax
would pay with tax included 24397.2
she can buy the car with cash
Step-by-step explanation:
24300
24300 times 0.4 then do
9720 divided by 100
97.2
she would pay 97.2 in tax
24300 + 97.2 is 24397.2
would pay with tax included 24397.2
she can buy the car with cash
Say your function is
f(x) = 2x + 3
If f(x) is 2 & you want to find x, replace f(x) with 2:
2=2x+3
And solve for x:
-1=2x
x=-1/2
Hope this helps!
