Answer:
9x^2-9x-3
Step-by-step explanation:
3x*3x=9x^2
3x*-4=-12x
1*3x=3x
1*-4=-3
9x^2-12x+3x-3
9x^2-9x-3
Answer:
240 degrees
Step-by-step explanation:
Looking at the graph we can see that the first peak is at -30 degrees and the second peak is at 210 degrees.
210 - (-30) = 210 + 30 = 240
It is approximately -.4048
H=10^(-pH)
log H = -pH
pH=-logH => so it is affirmed that it is -.40
