Answer:
v = 0.416 m/s
Step-by-step explanation:
Give that,
Distance covered by a train, d = 50 m
Time taken, t = 120 s
We need to find the speed of a train. The formula for speed of an object is equal to the total distance covered divided by total time taken. It can be given by :
So, the speed of a train is 0.416 m/s.
Add the x's and divide by 2 and then add the Y's and divide by 2
X: (-8 + -7)/2 = -15/2
Y: (-7+-8) /2 = -15/2
midpoint = (-15/2, -15/2)
Answer is C
Answer:
she swam 1500 meters in 1/4 of the time and he swam 750 in half of his time. Hope this helps
The equation is already in slope - intercept form y=mx+b, where m = slope, so m=4
The slope is 4
Answer:
I think it is D
Step-by-step explanation:
Its saying that f of x is four times x. So if x was one it could be four. But if x was greater than one it would be higher than one. Therefore, I think that the answer should be all real numbers greater than or equal to four.
Hope this helped!!! Let me know if I was correct. Haven't done this in years.
