If f(x) = x2 and g(x) = x + 6, find g(f(0)).
Pachacha [2.7K]
Hi friend,

f(x) = x²
g(x) = x+6

f(0) = 0² =0

g ( f(0) ) = f(0) +6

The current of a river is 3 miles per hour. A boat travels to a point 176 miles upstream and 176 miles back in 19 hours. What is
serious [3.7K]

Answer:

If I am understanding your question, the total upstream is 8 miles and another 8 miles downstream.

Let s = the speed of the boat in still water

d = rt

8 = 5(s + 3)  downstream

8 = 5s + 15  equation 1

8 = 5(s - 3)   upstream

8 = 5s - 15    Add equation 1

8 = 5s + 15 

16 = 10s    Divide both sides by 10.

s = 16/10 = 8/5 = 1.6 mph
