Answer:
A
Step-by-step explanation:
The n th term ( explicit formula) for a geometric sequence is
f(n) = a
where a is the first term and r the common ratio
Here a = 2 and r = - 8 ÷ 2 = - 4, thus
f(n) = 2
Answer:
c)A cylinder with a volume of π(w³ +2w² )in³
where w represents the width of the cylinder.
Step-by-step explanation:
A cylinder with a volume of π(w³ +2w² )in³
where w represents the width of the cylinder.
The volume of a cylinder is given by V=Bh or V=πr²h
where B is the area of the base and h is the height of the cylinder.
V=πr²h-------equation1
V= π(w³ +2w² )--------- equation2
Comparing equation 1 and equation 2
πr²h=π(w³ +2w² )
r²h=(w³ +2w² )
r²h= w²(w +2 )
Taking w² common leaves w+2 which gives the height or length of the cylinder.
Therefore radius = width and height = length which gives the volume of the cylinder.
Hey! y is 100, x is 80.
hope this helped <3
I got 125.845 ft. I hope this is right!
Let's call the height of the tower 
and the distance from the 65 degree angle to the base of the tower 
.
We get two equations:
