Alexeev081 [22]

Answer:

140 individuals were surveyed

42 people are planning on going to the mountains

Step-by-step explanation:

The question is missing the information regarding the percentage of people who said that they were going to each of the possible destinations. After a quick google search I've found that, in the original question, 32% of individuals were going to the beach, 15% to the desert, 23% to major cities, and 30% to the mountains.

If 21 people said they were going to the desert, and that corresponds to 15% of the total number of people surveyed, the number of people surveyed is:

$21=n*0.15\\n=140\ individuals$

140 individuals were surveyed

Since 30% responded "the mountains", the number of people planning on going to the mountains is:

$m = 140*0.30\\m=42\ people$

42 people are planning on going to the mountains

The product of two even numbers is always divisible by 4 true or false

never [62]

Answer: TRUE

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

an even number is divisible by 2.

Consider even number j which equals 2a and even number k which equals 2b. Then the product of these two numbers (j and k) = 2a*2b = 4ab.

4ab is divisible by 4.

BONUS:

The product of three even numbers is divisible by 2³

The product of four even numbers is divisible by 2⁴

The product of five even numbers is divisible by 2⁵

do you see the pattern?

Using complete sentences, explain the key features of the graph of the tangent function.

Temka [501]

Answer:

We are given the tangent function $f(x)=\tan x$ .

Firstly we know that, $\tan x=\frac{\sin x}{\cos x}$ , where $\sin x$ is the sine function and $\cos x$ is the cosine function.

Now, tangent function will be zero when its numerator is zero.

i.e. $\tan x=0$ when $\sin x=0$ .

i.e. $\tan x=0$ when $x=n \pi$ , where n is the set of integers.

So, tangent function crosses x-axis at $n \pi$ , n is the set of integers.

Further, tangent function will be undefined when its denominator is zero.

i.e. $\tan x=0$ when $\cos x=0$ .

i.e. $\tan x=0$ when $x=(2n-1) \frac{\pi}{2}$ , where n is the set of integers.

Moreover, a zero in the denominator gives vertical asymptotes.

So, tangent function will have vertical asymptotes at $(2n-1) \frac{\pi}{2}$ , n is the set of integers.

Therefore, these key features gives us the graph of a tangent function as shown below.
