Someone please help, it was due yesterday UwU
irakobra [83]

Answer:

Step-by-step explanation:

Part A - Where did Phillip make a mistake? Justify your answer using complete sentences.

Use order of operation (PEMDAS)

He should multiply 8 x 4 first

Part B - Solve the expression correctly in the space below.

(5 x 9) - 8 x 4

= 45 - 32

= 13

Part C - Use the same rules of order of operations to solve the expression (8-4) +9 x 3. Explain your steps as you solve it.

(8-4) + 9 x 3

Step 1:   4 + 9 x 3  (Subtract in the parenthesis first)

Step 2:   4 + 27   (Multiply 9 x 3)

Step 3:   31         (Add)

First, recall that

\sin(-\theta)=-\sin\theta

So if \sin(-\theta)=\dfrac15, then \sin\theta=-\dfrac15.

Second,

\tan\theta=\dfrac{\sin\theta}{\cos\theta}

We know that \tan\theta>0 and \sin\theta, which means we should also have \cos\theta.

Third,

\sin^2\theta+\cos^2\theta=1\implies\cos\theta=\pm\sqrt{1-\sin^2\theta}

but as we've already shown, we need to have \cos\theta, so we pick the negative root.

Finally,

\tan\theta=\dfrac{\sin\theta}{\cos\theta}\iff\dfrac6{\sqrt{12}}=\dfrac{-\frac15}{\cos\theta}\implies\cos\theta=-\dfrac1{5\sqrt3}

Unfortunately, none of the given answers match, so perhaps I've misunderstood one of the given conditions... In any case, this answer should tell you everything you need to know to find the right solution from the given options.
