arcsin(1/2) means "the angle whose sine is 1/2".

That's 30° .

y = cos(30°) = (1/2)√3 = about 0.866 .

Matching quantities with units
Mrrafil [7]

Answer:

1. Volume = length x width x height => cubic centimetres.

2. Perimeter = 2(length) + 2(width) => metres.

3. Speed = Distance /time => metres per second.

4. Area = length x width => square metres.

Step-by-step explanation:

1. Volume = length x width x height

If the length, width and height are measured in centimetre (cm) , then, the unit of the volume will be:

Volume = cm x cm xcm = cm3 i.e cubic centimetres.

2. Perimeter = 2(length) + 2(width)

If the length and width are measured in meter (m), then, the unit of the perimeter will also be in metre (m).

3. Speed = Distance /time

If the unit of distance is measured in metre (m) and the time is measured in second (s), then , the unit of the speed will be:

Speed = Distance /time = m/s i.e metres per second.

4. Area = length x width

If the length and width are measured in metres (m), then, the unit of the area will be:

Area = m x m = m2 i.e square metres

Solve the radical equation. Be sure to check all solutions to eliminate extraneous solutions.
tatyana61 [14]

Answer: \large\boxed{\text{No Solution}}

Step-by-step explanation:

<u>Given equation</u>

\sqrt{t+1}+9=7

<u>Subtract 9 on both sides</u>

\sqrt{t+1}+9-9=7-9

\sqrt{t+1}=-2

<u>Conclusion</u>

\text{Since radical values are always positive, it is false that }\sqrt{t+1}\text{ will equal to -2}

\text{Therefore, it is }{\large\boxed{\text{No Solution}}}\text{ in the context of real numbers}

Hope this helps!! :)
