Problem
Solution
For this case we know that the vertex is given by (3,6) and the genera equation for a parabola is given by:
y= a(x-h)^2 +k
Where h = 3, k=6 and replacing we have:
y= a(x-3)^2 +6
And we can find the value of a with the point given x= 4, y=4
4= a(4-3)^2 +6
4= a +6
a= 4-6=-2
And the correct equation would be:
d. y= -2(x-3)^2 +6
For this case we have to:
d: Let the variable representing the number of miles traveled per day
Then, the cost will be given by the following equation:
If we have the cost , then the number of miles traveled is:
Thus, the number of miles traveled is 60.
Answer:
For a , the number of miles traveled is 60
Starting with ...
1) Multiply by the inverse of the coefficient multiplying the sum with M, then subtract m.
2) Multiply by g/T²
