Consider the given geometric sequence.

16, 32, 64, 128,

50
given that the sequence is represented by the function f, complete the statements.

the common ratio is

f(1) =

f(5) =

The common ratio is  2.

Step-by-step explanation:

The given geometric sequence. is

16, 32, 64, 128, ...

Also, The common ratio (r)=

Hence, the common ratio (r)= 2

Given that the sequence is represented by the function f.

Then

Then, the first term of G.P. =

For n=5,

Hence, f(5)=256

for me what is finding a good play list and going out because i can not lay down and relax so i usually go to a coffee shop. i also use the gum trick and this actually works. another advice is highlighting subjects it really does me remember certain things

step-by-step explanation:

answer:

total cost for tiles and paints is $924.  

step-by-step explanation:

we have been given that a community hall is in the shape of a cuboid. the hall is 40m long 15m high and 3m wide.

the paint will be required for 4 walls and ceiling.

let us find area of walls and ceiling.

therefore, the area of walls and ceiling is 1410 square meters.

given: cost for 10 litre of paint is $10 and 10 litre paint covers 25 square meter. therefore,

therefore, the total painting cost is $564.

tiles will be required for floor. let us find the area of floor.

given: 1m squared floor tiles costs $3. so,

therefore, the total tiles cost is $360.

now let us find combined total cost of tiles and paint.

therefore, the combined total cost of tiles and paint is $924.
