§ HELP PLS 10 POINTS PLEASE ANSWER BOTH QUESTIONS

okay let me try to do this

Step-by-step explanation:

so the first on is the graph on the top right, because the others wouldn't work. They wouldn't work because one is curved, one is 4 different lines, and one is not a straight line. so the top right is the function.

for the second question, the answer is either the top or second top (i think) because the second up from bottom makes no sense (why would you choose something that fails the vertical line test?) and the bottom doesn't make much sense either.

i hope this helped! sorry i couldn't give you a complete answer to the second question. TwT

the expression (1.26)2t reveals the approximate rate of increases in the number of plants semiannually.

hope this : )

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.
