Given:
The length of field is n yards.
The length of a field in feet is a function f(n).
To find:
The function rule for this situation.
Solution:
We know that,
1 yard = 3 feet
Using this conversion, we get
n yard = 3n feet
The length of field is n yards. So, the length of the field is 3n feets.
The length of a field in feet is a function f(n). So,
Therefore, the required function rule for this situation is .
For each sub-problem shown below, I'm using the distance formula to compute the distance between the two points
------------------------------------------------------
For the points (-10,2) and (-2,2), the distance is...
d = sqrt((x2-x1)^2+(y2-y1)^2)
d = sqrt((-2-(-10))^2+(2-2)^2)
d = sqrt((-2+10)^2+(2-2)^2)
d = sqrt((8)^2+(0)^2)
d = sqrt(64+0)
d = sqrt(64)
d = 8
------------------------------------------------------
For the points (-3,-1) and (5,1), the distance is...
d = sqrt((x2-x1)^2+(y2-y1)^2)
d = sqrt((5-(-3))^2+(1-(-1))^2)
d = sqrt((5+3)^2+(1+1)^2)
d = sqrt((8)^2+(2)^2)
