There are three groups. One group for girls. One group for half the boys which is equal to one group of girls and another identical sized group of boys because there are twice as many boys as girls.
48=total
3=number of groups
48/3=16
16 is equal to the number of girls because it is equal to half the number of boys
16*2=32
32+16=48
Number of boys plus number number of girls: 32+16=48

Step-by-step explanation:
They are adding 3 sticks each time so n=3
I hope this helps
Speed=s'
acceleration=s''
take derititive to find speed
a.
I willl assume you know the power rule so
s'=6t²-18t+12
solve when s'=36
36=6t²-18t+12
6=t²-3t+2
0=t²-3t-4
0=(t-4)(t+1)
set to zero
t-4=0
t=4
t+1=0
t=-1, false no negative times allowed
at t=4 or 4 seconds
b. at t=4
take deritive again
s''=12t-18
at t=4
s''=12(4)-18
s''=48-18
s''=30
acceleartion is 30mpsps
a. at t=4
b. 30 meters per second per second
The correct answer is y= x^2-16
