The input number is supposed to be substituted for x in the (3x + 5)
so the first one would be (3(0) + 5) = 5
Answer:
The domain of a composite function f(g(x)) f ( g ( x ) ) is the set of those inputs x in the domain of g for which g(x) is in the domain of f .
$100x should be greater than or equal to $2500. X being the number of computers sold. If you divide 100 by 2500 you will know how many computers he need to sell.
$100x >(or equal to) $2500
Here we're interested in the circumference: C = pi*d. In this case C = 3.14*(28 inches) = 88 inches.
Now divide this 88 inches into 200 feet to get the # of revolutions ncessary to travel 200 feet.
200 feet 12 in
------------ * --------- = 2400 inches
1 1 ft
2400 inches
----------------------- = 27.2 revolutions (answer)
[ 88 inches/ rev ]
