1) A peregrine falcon dives vertically according to the equation y = 15 m/s + (2.4 m/s^2) t^2 A. Calculate the displacement traveled after t = 1.1 seconds

B. Find the average velocity from t = 0.0 s to t = 1.1 seconds

C. Find the instantaneous velocity at t = 0.80 s

D. Find the expression for the velocity at any time, t

.

Step-by-step explanation:

It is given that and .

For ,

Divide both sides by 2.

     ...(i)

For ,

Divide both sides by 6.

     ...(ii)

From (i) and (ii), we get

Therefore, the required answer is .

answer:

what is your question that you ask

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.
