Let f(x) = 3x - 6 and g(x) = x - 2. Find f(g(5)) - ie. (f o g)(5) and its domain

1 answer:

4 0

Do this by finding g(5) first. Replacing x with 5 in g(x) gives you that g(5) = 3. Now replace that 3 in the x in f(x) to get that f(3) = 3. As far as the domain goes,, they are both lines and the domain for lines is all real numbers.

A flea is sitting on the very tip of the minute hand on a grandfather clock. The minute hand measures 6 inches long. How far doe

12345 [234]

In one day there are 24 hours, and each hour there are 60 minutes, so the minute hand makes 24*60=1440 full circles in one day. For each circle, the tip of the minute hand travels the entire circumference, which is 2*pi*r = 2*pi*(6 inches) = 12*pi inches. Multiplying by 1440 circles per day gives a distance of:
17280*pi inches, or 54,287 inches.

Half of a number plus 12 is 46

asambeis [7]

Let the number = x
x/2 + 12 = 46
x/2 = 46 - 12
x/2 = 34
x = 34 * 2
x = 68

So, your final answer is 68
