answer:

f (2) = 6

step-by-step explanation:

first plug in 2 as x
f(2) basically means x = 2

f (2) = 3(2)^0 - 2(2)^-1 + 4

solve the exponents and use PEMDAS

f (2) = 3(2)^0 - 2(2)^-1 + 4

f (2) = 3 - 1 + 4

2 to the 0th power is 1
3 times 1 is 3 so we get 3
2 to the power of -1 is 1/2 (it gets flipped)
-2 times 1/2 is -1 so we get 1
there is nothing to do with +4 so we bring it down
now, simply solve it using PEMDAS

f (2) = 3 - 1 + 4

f (2) = 2 + 4

f (2) = 6

I am pretty positive that it would, the circumference of the tube comes out to roughly 6.28 inches, so thee 8 inch wrapping paper should cover it nicely. Now the sheet of paper is only 2 inches longer than the tube, so the paper will only extend one inch above the tubes edge on either end. the tube has a diameter of 2 inches, so the 1 inch extension all around the tube should fold in and match up quite nicely.

Answer:

The many members should the club expect to have 5 years from now is 167.

Step-by-step explanation:

The number of members in the club at present is, 45.

It is provided that each year the club's enrollment increases by 30%.

Compute the increasing rate as follows:

$Rate=1+0.3=1.3$

Then the number of members in the club after <em>n</em> years is given by the equation:

$Number\ of\ members\ after\ n\ years=45\times (1.3)^{n}$

Compute the number of members in the club after 5 years as follows: $Number\ of\ members\ after\ 5\ years=45\times (1.3)^{5}\\=45\times (1.3)^{5}\\=45\times 3.71293\\=167.08185\\\approx167$
