Let us consider the initial position of train A, 
. This implies that 
.
Moreover, we have
This implies that the two equations are
The two trains meet if and only if their positions are the same, at the same time:
So, the two trains meet after 2 hours.
Answer:
The first graph will give the actual solution for f(x) = g(x).
Step-by-step explanation:
The first function is 
and 
.
Now, f(0) = 1 and g(0) = 1
So, the point (0,1) is a solution for f(x) = g(x).
Again, 
and 
.
Hence, the point (2,4) is also a solution of f(x) = g(x).
Therefore, the first graph will give the actual solution for f(x) = g(x). (Answer)
Answer: The answer is given below
Step-by-step explanation:
From the question, we are informed that in a study of weight loss programs, four subjects lost an average of 47 pounds and it is found that there is about 36% chance of getting such results with a diet that has no effect.
• Does the weight program have statistical significance?
When a result is statistically significant, it means that given the null hypothesis, the occurrence of such result is unlikely to happen.
In this scenario, No, the program isn't statistically significant. This is due to the fact that the occurence of the result may be by luck or chance.
• Does the weight loss program have practical significance?
Yes, the weight loss program have practical significance. This is due to the fact that the amount of weight that has been lost is actually big enough and hence can be said to be practically significant.
Answer:
y=(1/4)x+17/4
Step-by-step explanation:
find slope (m)
m= (2-5)/(-9-3)
m=-3/-12
m=1/4
plug into point-slope form
(im using point (3,5))
y-5=1/4(x-3)
y-5=1/4x-3/4
y=1/4x+17/4
hope this helped
