We are trying to represent the change in position of a bird flying down 7 ft to the ground.
Often, for the y axis- up is positive and down is negative.
Change in position is displacement- how far it was from the starting point
( different from distance which is how far is traveled
ex. doubling back would have distance they traveled some distance while the displacement is 0 because they are back to where they started).
The bird is going down 7 ft from where it originally was, which can be represented by
Bird's displacement = -7 ft
Answer:
-7/25, 6/40, 11/20, 6
Step-by-step explanation:
-3x^2+12x-15=0
-3x^2+12x =15
-3x^2+12x+36=15
Answer:
300 would be
Step-by-step explanation:
Since it’s a 20:600 ratio you can just convert it and that would be a 1:30 ratio
