It stretches the graph parallel to the y axis by a factor a. This has the effect of making the parabola more narrow.
Answer:
If you study for the test then you will get a good mark
Opposite exterior angles are congruent.
DGH = AEG
DGH = 110
First, it would be helpful to find out how many teachers there are at the school.
2470 students x (1 teacher/26 students)=95 teachers
To find the number of teachers needed, just use the ideal ratio:
2470 students x (1 teacher/19 students)=130 teachers
So to reduce this ratio to 19:1, the school needs 130 teachers. To know how many new teachers the school needs, just subtract the ideal from the current amount.
130-95=35 new teachers needed
