Answer:
405
Step-by-step explanation:
r sequence= 5,15,45,135
d sequence:=10,30,90,270
r ratio is the Radio
d ratio is de Diameter
2*r=d
5*2=10, 15*2=30, 45*2=90, 135*2=270
to complete the sequence:
r+d= next r and continue
5+10=15
15+30=45
45+90=135
135+270=405

Answer:
f(x) = 2+5
g(x) = 2(-(x−3))+5
Step-by-step explanation:
If you remember, an absolute value can have two different answer, a positive and negative answer because the absolute value symbol makes all values in it positive. Example: |-2|=2 and |2|=2
So if y = 2|x−3|+5
then the two possibilities are
y = 2(x−3)+5 and
y = 2(-)+5
Set one of them equal to f(x) and the other one to g(x)
f(x) = 2(x−3)+5
g(x) = 2(-(x−3))+5
You can also write it as a piecewise function.

Answer:
the sides the formula for that is 2(pi)radius(height). the formula for the total surface area is 2(pi)radius(height) + 2(pi)radius squared.
