Answer:

b=3, or 0

Step-by-step explanation:

\mathrm{Using\:the\:Zero\:Factor\:Principle:\quad \:If}\:ab=0\:\mathrm{then}\:a=0\:\mathrm{or}\:b=0

b=0\quad \mathrm{or}\quad \:9b-27=0

9b-27=0, \mathrm{Add\:}27\mathrm{\:to\:both\:sides}.

9b-27+27=0+27

9b=27

\mathrm{Divide\:both\:sides\:by\:}9

\frac{9b}{9}=\frac{27}{9}

b=3

Find all the powers of 4 in the range 4 through 1000
marissa [1.9K]
Powers of 4 are like 4^1, 4^2, 4^3 and so on
remember that 4^x means 4 times itself x times for example
4^3=4 times iteslef 3 times=4 times 4 times 4

so the multipules of the powers of 4 are just 4 times of the previous
so we will list

4^1=4
4^2=16
4^3=64
4^4=256
4^5=1024

1024 is already more than 1000 so the list stops and is
1,16,64,256

A bouncing ball reaches a height of 54 inches at its first peak, 36 inches at its second peak, and 24 inches at its third peak.
marin [14]
36/54=2/3
36/24=2/3

so each time it bounches 2/3 or what it bounced before

seems to be a geometric sequence
an=a1r^(n-1)
a1=first term
r=common ratio
a1=54
common ratio is 2/3
an=54(2/3)^(n-1)
