You cannot evaluate for (g o f)(0). You will get an undefined answer.
(g o f)(x) tells you to plug in the f(x) function for the x-variable in the g(x) equation; so it would be like saying g(f(x)). This would result in (g o f)(x) = (1/x) - 4. Now plug in 0, (g o f)(0) = 1/0 - 4. One cannot divide by zero in order to simplify the equation and get an answer... unless an undefined answer counts, which I'm pretty sure it doesn't.
400 I think I am not sure tho hope this helps
Answer:
Talking 65 minutes, $ 6.50 must be paid.
Step-by-step explanation:
Since your cell phone plan is by the minute, and each minute of use cost $ 0.10, to create a relation that represents the amount spent, A, per minute, m, of call time, and then use the relation to find the amount spent if you talk 65 minutes, the following calculations must be performed:
0.10 x M = A
0.10 x 65 = A
6.50 = A
Answer:
13,780.8 feet
Step-by-step explanation:
1 mile = 1.609km
1 mile = 5,280ft
Convert 4.2km to miles
1.609km = 1 mile
4.2km = 4.2/1.609 miles
= 2.610 miles
Convert 2.610 miles to feet
1 mile = 5,280ft
2.610 miles = 2.610 × 5,280
= 13,780.8 feet
