What is equivalent to the expression below?

To which set of numbers does the name belong ? . square root 51 . A. rational numbers . B. Irrational numbers . C integers . D n

deff fn [24]

The set of numbers $\sqrt{51}$ belongs to is termed as B. irrational numbers.

There are two main types of numbers, real and imaginary. Real numbers are also subdivided into rational and irrational numbers. Irrational numbers are numbers that cannot be written in a fractional form which is the opposite of rational numbers. These can either be non-terminating or repeating. An example of a non-terminating irrational number is the value of pi (3.1415...) and an example of a repeating irrational number is 15.55555...

I don't know what to do. This is about odd and even functions.

Alexxandr [17]

Answer:

C.

Step-by-step explanation:

We are given $f,g$ are odd which means:

$f(-x)=-f(x)$

$g(-x)=-g(x)$

We can tell if a function, $h$ , is even if $h(-x)=h(x)$ .

We can tell if a function, $h$ , is odd if $h(-x)=-h(x)$ .

So let's test your I,II,III.

We will be replacing x with -x to find out.

I.

$p(x)=f(g(x))$

$p(-x)=f(g(-x))$

$p(-x)=f(-g(x))$

$p(-x)=-f(g(x))$

$p(-x)=-p(x)$

So $p$ is odd.

II

$r(x)=f(x)+g(x)$

$r(-x)=f(-x)+g(-x)$

$r(-x)=-f(x)+-g(x)$

$r(-x)=-(f(x)+g(x))$

$r(-x)=-(r(x))$

$r(-x)=-r(x)$

So $r$ is odd.

III

$s(x)=f(x)\cdot g(x)$

$s(-x)=f(-x) \cdot g(-x)$

$s(-x)=-f(x) \cdot -g(x)$

$s(-x)=f(x) \cdot g(x)$

$s(-x)=s(x)$

So $s$ is even.

So I and II are odd and III is even.

C. is the answer.

HELP ME WITH THIS 60 POINTS,5-STAR RATING, AN THANKS AND MARKED AS BRANLIEST.

Greeley [361]

Answer:

1. C.

2. B.

3. Add 6.1 to both sides

Step-by-step explanation:

1. Your equation here is "w + 2 < -1"

You must get w by itself, so to do that, subtract 2 from both sides.

w + 2 < -1

w < -3

Notice that the symbol is "w is less than -3" not "w is less than or equal to -3," so our plot must have a closed circle (or no open circle).

The larger the number behind the negative sign, the smaller it is.

ex: -3 is smaller than -1

So, the answer is C.

2. Here, you have the inequality -15 > q - 5

To find out which number set best fits the inequality, substitute the numbers in for the q value.

[I'll skip to answer B.]

B.'s number set is {-11, -12, -14}

So, plug in each value for q

For -11:

-15 > (-11) - 5

-15 > -16

This works.

(As I mentioned earlier, the larger the number in front of the negative, the smaller it is.)

For -12:

-15 > (-12) - 5

-15 > -17

This works as well

For -14:

-15 > (-14) - 5

-15 > -19

This works too

Thus, the answer is B.

3. And finally, you have the equation p - 6.1 = 10

To solve for p, make sure its alone on one side of the equation.

To do this, add 6.1 to both sides.

This is the first (and pretty much only) step to solve this equation

I hope this helps!!! :)

A boat attempts to sail due east at 15km/h, but is taken off course by a current of 5 km/h flowing in the southwest direction. F

Iteru [2.4K]

Answer:

10 km / hr

Step-by-step explanation:

Speed of boat = 15 km /hr

Speed of stream = 5km /hr .

Since both are acting opposite to each other . The the resultant speed with which it travels = 15 - 5 = 10 km/hr

4b − 8 = 12. with steps

balandron [24]

4b-8=12
+8 +8

4b=20

Divide both sides by 4
