When we build integers from natural numbers, we're looking for additive inverse of natural numbers?

What's an additive inverse? Well, for example, the additive inverse of 2 is a numbers $x$ such that

$2+x = 0$

We call this number -2. So, the real meaning behind the negative sign is "if you add me and my positive counterpart, the result is zero".

So, -5 is the additive inverse of 5, -16 is the additive inverse of 16, and so on, because

$5-5=0,\quad 16-16=0,\ldots$

Note that this is a symmetrical relation: if -5 is the inverse of 5, it is also true that 5 is the inverse of -5.

So, when you write something like

$5-(-4)$

it means that you want to add 5 and the inverse of the inverse of 4. But given what we just said, the inverse of the inverse of a number is the number itself, which is why subtracting a negative number is the same as adding it.

PLS HELP. AND SHOW WORK !!! NO BOTS PLS IM TIRED

julsineya [31]

Answer:

3) B and C

Step-by-step explanation:

h has to be -4 because two negatives cancel to make a positive, and the equation is $(x+4)^2+(y-3)^2$

k would be positive

h is the x value and k is the y value of the center point, so the coordinate of the center would be (-4, 3)

C is correct because $r^2=50$ in the equation, so r would be $\sqrt{50} =\sqrt{25} *\sqrt{2}=5\sqrt{2}$

if r was 25, $r^2$ would be 625 not 50

Find tanθ if sinθ=−25√5 is in the third quadrant.

irinina [24]

Using a trigonometric identity, it is found that the tangent of the angle is of:

$\tan{\theta} = \frac{2}{11}$

<h3>How to find the sine of an angle given the cosine, or vice versa?</h3>

The sine and the cosine of the angle are related according to the following identity:

$\sin^2{\theta} + \cos^2{\theta} = 1$

For this problem, the sine is given by:

$\sin{\theta} = -\frac{2}{5\sqrt{5}}$

Hence the cosine is found as follows:

$\left(-\frac{2}{5\sqrt{5}}\right)^2 + \cos^2{\theta} = 1$

$\frac{4}{125} + \cos^2{\theta} = 1$

$\cos^2{\theta} = \frac{121}{125}$

$\cos{\theta} = \pm \sqrt{\frac{121}{125}}$

On the third quadrant the cosine is negative, hence:

$\cos{\theta} = -\frac{11}{5\sqrt{5}}$

<h3>What is the tangent of an angle?</h3>

The tangent of an angle is given by the sine divided by the cosine, hence:

$\tan{\theta} = \frac{-\frac{2}{5\sqrt{5}}}{-\frac{11}{5\sqrt{5}}} = \frac{2}{11}$

The distance dd is 11 mm. What is the perimeter of the figure? Round to the nearest tenth.

Kisachek [45]

Answer:

P = 157.1 mm

Step-by-step explanation:

The perimeter of the figure = Circumference of circle + perimeter of square

We have, d = 11

⇒ Radius = 11 mm

Side of square = 22 cm

So,

$P=2\pi \times 11+4\times 22\\\\P=157.11\ mm\\\\or\\\\P=157.1\ mm$

So, the perimeter of the figure is equal to 157.1 mm.

I thought of a number, I added 1 3 4 to it, then I multiplied the result by 2 2 11 and I got 8. What was my number?

Natalija [7]

Question:

I thought of a number, I added 1 3/4 to it, then I multiplied the result by 2 2/11 and I got 8. What was my number?

Answer:

The number is $1\frac{11}{12}$

Step-by-step explanation:

Let the number be x.

Analyzing the steps, 1 at a time

Add $1\frac{3}{4}$ to x

This implies:

$x + 1\frac{3}{4}$

Multiply by $2\frac{2}{11}$ to result in 8

This implies:

$(x + 1\frac{3}{4}) * 2\frac{2}{11} = 8$

Now, we solve for x

Convert mixed numbers to improper fractions

$(x + \frac{7}{4}) * \frac{24}{11} = 8$

$(\frac{4x + 7}{4}) * \frac{24}{11} = 8$

Multiply through by 11

$11 * (\frac{4x + 7}{4}) * \frac{24}{11} = 8 * 11$

$(\frac{4x + 7}{4}) * 24 = 88$

Divide through by 24

$(\frac{4x + 7}{4}) * 24/24 = 88/24$

$\frac{4x + 7}{4} = \frac{88}{24}$

Multiply through by 4

$4 * \frac{4x + 7}{4} = \frac{88}{24} * 4$

$4x + 7 = \frac{88 * 4}{24}$

$4x + 7 = \frac{88}{6}$

$4x + 7 = \frac{44}{3}$

Make 4x the subject

$4x = \frac{44}{3} -7$

$4x = \frac{44-21}{3}$

$4x = \frac{23}{3}$

Solve for x

$x = \frac{23}{3 * 4}$

$x = \frac{23}{12}$

$x = 1\frac{11}{12}$

<em>Hence, the number is </em> $1\frac{11}{12}$ <em></em>
