Answer:

(11 - 5)n - 50

Step-by-step explanation:

Cost of 1 hat = $5
Selling price = $11
Advertising = $50

Let the number of hats be n. Then money made is

<u>Profit for each hat:</u>

(11-5)

<u>Profit for n hats </u>

(11 - 5)n

<u>Deduct cost of advertisement - 50</u>

(11 - 5)n - 50

Option C is correct

Find the value of cos θ if the angle θ is in the third quadrant and sinθ= -0.8

Rudiy27

Correct option is D) -0.6.

<u>Step-by-step explanation:</u>

We have $sin\alpha = -0.8$ . Also, we know that $cos\alpha = \sqrt{1- (sin\alpha } )^{2}$ . Let's find out value of $cos\alpha$ using above formula:

$cos\alpha = \sqrt{1- (sin\alpha } )^{2}$

⇒ $cos\alpha = \sqrt{1- (sin\alpha } )^{2}$

⇒ $cos\alpha = \sqrt{1- (-0.8 } )^{2}$

⇒ $cos\alpha = \sqrt{1- (0.64 } )^{}$

⇒ $cos\alpha = \sqrt{0.36}$

⇒ $cos\alpha = 0.6$

But we know that cos $\alpha$ is negative in third quadrant , Therefore $cos\alpha = -0.6$ .

Hence, correct option is D) -0.6.
