Evaluate sin^-1 1/2 . Round your answer to the nearest hundredth.
adoni [48]

Answer:

<h2>30.00</h2>

Step-by-step explanation:

Given the expression sin^{-1} 1/2, the following steps must be taken to evaluate the expression.

Let\  y = sin^{-1}1/2

y = sin^{-1} 0.5

From the calculator, the value of y wil give;

y = 30\\\\y = 30.00 (to\ the \ nearest \ hundredth)

Hence sin^{-1}  0.5 = 30.00.

For problems 1 - 4, write a two-column proof.
UNO [17]

The questions given in the pdf are these pictures, then we can get the solutions.

<u>1) Solution</u>

It is given that,

→ <5 = <6

Then the co interior angles,

→ <5+ <4 = 180°

Now substituting value of <5,

→ <6+ <4 = 180°

This shows property of co interior angle.

Therefore, L II m.

<u>2) Solution</u>

Take it as,

→ <1= 90°

In above eq. L is perpendicular to t.

→ <2 = 90°

In above eq. m is perpendicular to t.

Then it will be,

→ <1 = <2

It shows property of corresponding angle.

Therefore, L II m.

<u>3) Solution</u>

It is given that,

→ <1 = <2 and <1 = <3

Now substitute,

The value of <1 in second one,

→ <2 = <3

This shows property of alternate angle.

Therefore, ST II UV.

<u>4) Solution</u>

It is given that,

→ <RSP = <PQR --- (1)

→ <QRS + <PQR = 180° --- (2)

Now from the equation (1) and (2),

→ <RSP + <QRS = 180°

It shows property of co interior angle.

Therefore, PS II QR.

<h3>Answer:  11/12</h3>

============================================================

Explanation:

3/4 = 9/12 after multiplying top and bottom by 3

1/3 = 4/12 after multiplying top and bottom by 4

When combining the fractions 3/4 and 1/3, we get,

3/4 + 1/3 = 9/12 + 4/12 = (9+4)/12 = 13/12

Let's convert that result into a mixed number

13/12 = (12+1)/12

13/12 = 12/12 + 1/12

13/12 = 1 + 1/12

13/12 = 1 & 1/12

Adam and Brian have collectively eaten 1 full pizza plus an additional 1/12 of the second pizza. This leaves 11/12 of the second pizza for Christine to eat. Notice how the fractions part 1/12 and 11/12 add to 12/12 = 1.

Check out the diagram below.
