Answer:
-5/3 = m
Step-by-step explanation:
Don't you mean (4, -1) and (1, 4)? If so, if we start with (1, 4) and move to (4, -1), then x (the "run") increases by 3 and y (the "rise") decreases by 5. Then the slope is m = rise / run = -5/3 = m
Answer:
The answer would be A
Step-by-step explanation:
Answer:
Distance around the track = 194.3 metres.
Step-by-step explanation:
Given: The two straight sides are of the track are 50 metres each
Diameter of each bend = 30 metres
Thus;
radius of the bends =
=
= 15 metres
So that,
length of the semicircular bend = x 2r
= r = x 15
= 47.143
length of each semicircular bend is 47.14 metres.
Distance around the track = addition of the length of each straight sides + addition of the length of the bends
= 50 + 50 + 47.14 + 47.14
= 194.28
Therefore,
Distance around the track = 194.3 metres.
To solve this problem you must apply the proccedure shown below:
1. By definition, the rate of change of a linear function is the slope of the line and it is constant. Based on this, you must find the slope of the given function.
2. You have the equation of the line has the following form:
Where is the slope and is the y-intercept.
3. Then, you have that the slope of the function is:
Therefore, the answer is:
