In a right triangle there are 2 legs and a hypotenuse. The way you can tell if it's a right triangle is by finding the slope of both the legs. If their slopes are opposite reciprocals of each other, then they are perpendicular. By definition, perpendicular lines meet to create a right angle.
It would be 6912 minutes. Hope this helps
S = d/t
st = d
t = d/s
The time going is t1.
The time returning is t2.
The total time is 4 hours, so we have t1 + t2 = 4
The speed of the current is c.
The speed going is 9 + c.
The speed returning is 9 - c.
t1 = 16/(9 + c)
t2 = 16/(9 - c)
t1 + t2 = 16/(9 + c) + 16/(9 - c)
4 = 16/(9 - c) + 16/(9 + c)
1 = 4/(9 - c) + 4/(9 + c)
(9 + c)(9 - c) = 4(9 - c) + 4(9 + c)
81 - c^2 = 36 - 4c + 36 + 4c
81 - c^2 = 72
c^2 = 9
c^2 - 9 = 0
(c + 3)(c - 3) = 0
c + 3 = 0 or c - 3 = 0
c = -3 or c = 3
We discard the negative answer, and we get c = 3.
The speed of the current is 3 mph.
Answer:
0000000000000000
Step-by-step explanation:
The factors are: x-5 and x+3
Step-by-step explanation:
Given
Simplifying
Let us define the zero product property first
The zero product property states that
if ab=0 then either a=0 or b=0
So,
Hence,
the factors are: x-5 and x+3
