<h2>Hello!</h2>

The answer is:

C. Cosine is negative in Quadrant III

Let's discard each given option in order to find the correct:

A. Tangent is negative in Quadrant I: It's false, all functions are positive in Quadrant I (0° to 90°).

B. Sine is negative in Quadrant II: It's false, sine is negative in positive in Quadrant II. Sine function is always positive coming from 90° to 180°.

C. Cosine is negative in Quadrant III. It's true, cosine and sine functions are negative in Quadrant III (180° to 270°), meaning that only tangent and cotangent functions will be positive in Quadrant III.

D. Sine is positive in Quadrant IV: It's false, sine is negative in Quadrant IV. Only cosine and secant functions are positive in Quadrant IV (270° to 360°)

Have a nice day!

Find the number whose 8% is 48?

Black_prince [1.1K]

Answer:

Step-by-step explanation :

Let x be the number.

x × 8/100 =48

x =48 × 100/8

Now cut 48 by 8 and we get 6.

x = 6 ×100

x =600

So 600 is the required number.

*Need Help??!!

RoseWind [281]

The probability of getting a <em>country CD</em> out of all the CDs is the number of <em>country CDs</em> divided by the <em>total number of CDs</em> in Dante's Collection.

The <em>total number of CDs</em> in Dante's collection is $6+12+8+4+10=40$ .

The total number of <em>country CDs</em> is 12.

So our required probability is $\frac{12}{40}= \frac{3}{10}$ .

In percentage this is 3 divided by 10, and then multiply by 100. We get 30%. Answer choice D is correct.

Explain the difference between exponential growth and exponential decay

alexdok [17]

Exponential growth is the function
$y = a^{x} , a\ \textgreater \ 1$
Exponential decay is the function
$y = a^{x} , 0\ \textless \ a\ \textless \ 1$
So, the basic difference is that in growth the base is more than 1, and in decay the base is more than 0 but less than 1.
