Checking the graph:- when x = 1 y = 0 so it cant be y = x^4
y = log4 x
is the same as
x = 4^y
Checking the graph, when x = 4, y = 1
Plugging these into the above 4 = 4^1 = 4
So the correct choice is first one
Theirs your answer 661.091628959
50 km/h = 4 hours
60 km/h = x hours
50x = 60×4
50x = 240
x = 4.8 hours
Answer:
the two lengths= 194 each side
teh two widths= 49 on each side
194+194+49+49= 486
Step-by-step explanation:
486= 2l+2w
l=4w-2
486-2w=2l -divide that by 2
243-w=l
243-w=4w-2
245=5w -divide that by 5
49=w
l=4(49)-2
l=194
w=49
