Help please explain ​
MatroZZZ [7]

Given:

\sin^{-1}\left(\dfrac{5}{8}\right)=A

To find:

The correct equivalent equation.

Solution:

We have,

\sin^{-1}\left(\dfrac{5}{8}\right)=A

Taking sin on both sides, we get

\sin \sin^{-1}\left(\dfrac{5}{8}\right)=\sin A

\dfrac{5}{8}=\sin A                      [\because \sin (\sin^{-1}\theta )=\theta]

Interchanging the sides, we get

\sin A=\dfrac{5}{8}

Therefore, the correct option is 4.

Is this ordered pair a solution to the inequality?<br> (1, 3)<br> 5x+y&lt;-3<br> A.)No<br> B.)Yes
max2010maxim [7]
(1,3) means that x = 1 and y = 3. Let's make substitutions to see what happens with the inequality

5*x + y < -3
5*1 + y < -3 ... replace x with 1
5*1 + 3 < -3 ... replace y with 3
5 + 3 < -3
8 < -3

This is false. The number 8 is NOT smaller than -3. 

So (1,3) is NOT a solution

Answer: Choice A) No
