Answer:
Step-by-step explanation:
plot an open circle on the 4 and a closed circle on the 10. Then draw a line that goes from 4 to 10.
Answer:
The distance between the two points is 13 units.
Step-by-step explanation:
take the test
Speed = Distance / Time
Distance = Speed*Time
For this problem, we should bear in mind that current speed has an impact on the boat speed...
for upstream, the boat goes against the current, and so its speed is
U = V - C
where V is the speed of the boat
C is the current speed
for downstream, it will be:
D = V + C
Convert the problem into mathematical equations:
4D + 3U = 116
3D + 4U = 108
4(V+C) + 3(V-C) = 116
4V + 4C + 3V -3C =116
7V + C = 116
3(V+C) + 4(V-C) = 108
3V + 3C + 4V - 4C = 108
7V - C = 108
Solving the equations:
7V + C = 116
7V - C = 108
14V = 224
V = 16km/hr —-> speed of boat
to get C:
7(16) + C = 116
C = 4km/hr
Answer:
Your answer would be 12

Hopefully this helped, if not HMU and I will try my best to get you a better answer! :)
A polynomial function with all even exponents is so-called even function.
Even functions are symmetric across the y-axis.
Answer: Only one that is symmetric across the x-axis is the function C ).
