Answer:
Step-by-step explanation:
this is an arithmetic series
and to find out the 9th term
1 second ....................... k feet
2 second...........................2.5 feet
3 sec.....................................4 feet
4 sec....................................5.5 feet
difference 1.5
5 sec................................7 feet
6 sec................................8.5
7 sec.................................10 ft
8
9second .............................................13 ft
First, we get ax^2+bx+c. Next, we know that the line of symmetry is -b/2a. Since we know that there is a maximum value, the parabola is facing downwards, so a is negative. For random numbers, we can say that a = -0.5 and b=-10 (b needs to be negative for -b/2a to equal -10), getting -0.5x^2-10x+c. Plugging -10 in for x (since -10 is the middle it is the max), we get -50+100=50. Since the maximum needs to be 5, not 50, we subtract 45 from the answer to get it and therefore make c = -45, getting -0.5x^2-10x-45
Based on sss because of congruent
The first one and the third one are correct. because for the when you plug 1 on the first piece wise function you get 3.
f(3) =1. and f(1)=3 so f(1)>f(3)
