one room length 12.8 and breadth equals to 850 CM inside that room there is a bad length is 300 cm and breadth is 400 cm find th
9966 [12]

Answer:

Area = 968000cm^2

Step-by-step explanation:

To be able to answer this question properly. I'll assume the length of the room is in meters.

So for the room, we have:

Length = 12.8m

Breadth = 850cm

For the bed, we have:

Length = 300cm

Breadth = 400cm

First, we calculate the surface area of the room.

A_1 = 12.8m * 850cm

Convert all units to cm

A_1= 12.8*100cm * 850cm

A_1= 1 088 000 cm^2

Next, we calculate the area of the bed

A_2 = 300cm * 400cm

A_2 = 120000cm^2

The area of the space left  is the difference between A1 and A2

Area = A_1 - A_2

Area = 1088000cm^2 - 120000cm^2

Area = 968000cm^2

What is the correct answer to this multiple choice question? Please help!!!
dybincka [34]

Answer:

By translating the function cos(x) 90 degrees to the right.

Step-by-step explanation:

The sine function is just the cosine function translated 90 degrees to the right. You can see the visualization below. They overlap.

If you're wondering why the diagram shows a shift in

\pi / 2

That's just the equivalent to 90 degrees in radians.
