The parent function is
That Parabola's equation is
Step-by-step explanation:
I can't really explain much, but the top equation is a formula for <em>all </em>equations for a parabola. h and k are the x and y-values of the vertex. a is, well, a.
How did I find the equation of the parabola? Simple. Since the vertex is on the origin, h and k are 0. Also, because it intercepts (2,4) and (1,1), a=1.
Answer:
Step-by-step explanation:
Hi!
The options regarding the inequalities are not listed, though we can still proceed to write the inequality.
From the problem statement you cannot spend more than $50
and you are charged admission fee of $6 flat
a ride cost $2.50 per ride
the number of rides is given as r
yet in all you must not go beyond your limit
Therefore the inequalities can be presented as
8 - (-10) = 18
18 / 3 = 6
hope this helps

Mean is best measure of average.
Given:
Class rank is at least = 90th percentile
Rank 30 out of 128 student
Find:
1. Invited for membership or not
2. Best measure of average
Computation:
Rank in total = [(100 - Percentile)(Total students)]/100
30 = [(100 - Percentile)(128)]/100
3000 = [(100 - Percentile)(128)]
23.4375 = 100 - Percentile
Percentile = 100 - 23.4375
Percentile = 76.5625
Since Percentile smaller than 90, So, you will not invited to membership
Mean is best measure of average.
