variation and find t when w = 5.
A. T=5/12w; 5/12
B.t=5/3w;1/3
C.t=5/48w;5/192
D.t=5/12w;1/3
Answer:
Option B. t=5/3w ;1/3
Step-by-step explanation:
We are told that varies Inversely with thus generally speaking ∝ since they are inverted, otherwise if they were proportionally varied then ∝. This means that there is a constant value ( ) for which is inversely proportional to and can be mathematically expressed as:
Eqn. (1)
Now since we are given the values of and , we can plug them in Eqn. (1) and find our constant of proportionality as follow:
Now that we have our constant we can find the new value for the second value of as follow:
Therefore based on the options give, we can see that Option B. is correct since
and for , then
Answer:
Step-by-step explanation:
Andrew has a cell phone plan that provides 300 free minutes each month for a flat rate of $19. For any minutes over 300, Andrew is charged $0.39 per minute.
Let x be the number of minutes Andrew uses per month and f(x) be the charges based on Andrew's cell phone plan.
If then
If then first 300 minutes are free and each minute of next (x-300) minutes costs $0.39, therefore
Hence,
Answer:
19, x≤ 300
19+.39(x-300), x>300
