Answer:
y=3/4(4)^x
Step-by-step explanation:
hello :
the graph passes through the point (1,3) : when x=1 and y=3 : 3= ab^1
the graph passes through the point (2,12) : when x=2 and y=12 : 12= ab^2
so the system : ab=3 ...(*)
ab² =12..(**)
ab² = b(ab) = 12 but : ab=3 so : (**) equivalent to b(3)=12 .... b=12/3=4
now : ab= 3 and b=4 so : 4a=3 ... a=3/4
y=3/4(4)^x
3.12 × 104. 3.12E4 = 3.12 × 10 × 10 × 10 × 10 = 31,200 ...
H = 52.2 diameter = 20 cm
<span>radius = 10 cm
Cylinder volume = π <span>• r² • height
</span></span><span>Cylinder volume = PI * 100*52.2
</span>
Cylinder volume =

16,399
answer is C

Ok, if you want to find out the range of the hours they play, here it is:
Since the number of hours for Bonnie are 4, 5, 4, 3, 3, 5, the range should be 3, 4, 5, which makes the range 3.
Since the number of hours for Adele are 5, 5, 9, 8, 8, 7, the range should be 5, 7, 8, 9, which makes the range 4.
Which means Adele's range is bigger than Bonnie's!
Hope this helped! c:
