Step-by-step explanation:
Rossi has 5 different movies to choose from, 8 restaurants to choose from, and 2 sporting events to choose from.
For each movie, he has 8 different restaurants to choose from, and for each of those restaurants, he has 2 sporting events to choose from.
Since he plans to go to each event in a specific order (movie -> restaurants-> sporting event), there are different dates possible.
we want to find the range of
Notice that Whatever value v can possibly produce, that is the Range of v, becomes the range of u.
Then whatever u produces for these values, is the range of u(v(x))
So, first find range of v: clearly the domain of v is R-{0}, as v(0) makes no sense.
We check what values c can v produce:
this means that any c (for now) can be produced... it is enough to let x=1/c
this also means that c cannot be equal to 0 as 1/c makes no sense if c=0.
Thus the range of v is R-{0},
Now we check the range of u(v(x)) for v(x)∈R-{0},
assume we want to produce a value c, so:
since the left side is always positive or 0, for x=0, the right hand side expression must also be positive or zero, which means c-3 must be negative or 0,
thus c-3≤0; c≤3. Here recall that x in u(x) cannot be 0, so c<3.
Answer: The range of u(v(x)) is (-infinity, 3)
Answer:
Step-by-step explanation:
1.)12.
To make it a fraction form answer, you multiply the whole number by the denominator and make the result the new numerator. The old numerator becomes the new denominator.
Thus, the answer to 4 divided by 1/3 in fraction form is:
To make the answer to 4 divided by 1/3 in decimal form, you simply divide the numerator by the denominator from the fraction answer above:
12
The answer is rounded to the nearest two decimal points if necessary.
is an improper fraction and should be written as 12.
2.) 9
