For this case we have the following functions:
By definition we have to:
So:
By definition, the domain of a function is given by the values for which the function is defined.
The domain of m(x) is given by all reals except 1.
The domain of n(x) is given by all reals.
While the domain of is given by:
All reals, except the 1. With , the denominator is 0 and the function is no longer defined.
Answer:
Domain of is given by all reals except 1.
Brand B............................
Company a = 22 + 0.07m
company b = 8 + 0.12m
We are looking for the time when the prices are equal. i.e. the price of company a = the price of company b
company a = company b
22 + 0.07m = 8 + 0.12m
22 - 8 = 0.12m - 0.07m
14 = 0.05m
m = 14/0.05
m = 280
Therefore, the two companies will cost the same if you talk for 280 minutes
Answer:
Explanation:
Compute the magnitude:
∣∣→a∣∣=√(−10)2+62+(−7)2
∣∣→a∣∣=√100+36+49
∣∣→a∣∣=√185
To obtain the unit vector of →a=(−10,6,−7), we divide each component by √185 but we should rationalize 1√185 to √185185:
ˆa=(−10√185185,6√185185,−7√185185)
