Achess competition has eliminations each round. the table below shows the number of players in each of the first 5 rounds of the tournament:

round (x) 1 2 3 4 5
players f(x) 256 128 64 32 16

compute the average rate of change of f(x) from x = 1 to x = 5 and identify the meaning of that rate.
−60; on average, there was a loss of 60 each round
−240; on average, there was a loss of 240 each round
4; there were 4 rounds between rounds 1 and 5
240; there were 240 fewer players between rounds 1 and 5

the answer is 99.

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.
