Answer:

a*a^{-1}=a*\frac{1}{a}= \frac{a}{a}=1 \\\\a\in R

Step-by-step explanation:

We are talking about the multiplicative inverse of any number. The multiplicative inverse of a number is another number that multiplied by the first, results in the neutral element of the product, that is, the unit. If we have a real number a, then its multiplicative inverse is denoted by a^{-1}, and it is true that:

a*a^{-1}=a*\frac{1}{a}= \frac{a}{a}=1 \\\\a\in R

It's important to note that the multiplicative inverse exists in rational numbers, in real numbers, and in complex numbers.

Kevin recorded the effects of violent video games on antisocial behavior.
den301095 [7]

Answer:

B.

Explanation:

Because the study is relying on the effects of violent video games and how it affects anti-social behavior.

If this was a math problem it'd be:

---> y= effect and signs of anti social behavior.

---> x= violent video games.

--->5= Hours spent playing. (Lets use 5 as a random number to write this as an equation then.)

Equation form:

Most likely would look something like this

(5x=y)

Hope this helped. I know it's late but it came up on my "Selected for you" section so I decided I'd answer it.

Find the product of (x^2+2x-3)(4x^2-5x+6)
Evgesh-ka [11]

Answer:

x^{4} + 3x³ - 16x² + 27x - 18

Step-by-step explanation:

Each term in the second factor is multiplied by each term in the first factor, that is

x²(4x² - 5x + 6) + 2x(4x² - 5x + 6) - 3(4x² - 5x + 6)

Distribute all 3 parenthesis

= 4x^{4} - 5x³ + 6x² + 8x³ - 10x² + 12x - 12x² + 15x - 18

Collecting like terms

= 4x^{4} + 3x³ - 16x² + 27x - 18

What number would complete the pattern? 107 98 90 83 77_68 65
Leviafan [203]
Going from 107 to 98 is (minus 9)
going from 98 to 90 is (minus 8)
going from 90 to 83 is (minus 7)
going from 83 to 77 is (minus 6)

following this pattern, the number after 77
is 77 minus 5 = 72

therefore your answer is 72

In the triangle ABC if angle A is 20 degrees, angle B is 35 degrees and the side between (side C) them is 100, what is the appro
docker41 [41]

Answer:length of side a is 42

Step-by-step explanation:

The given triangle ABC is shown in the attached photo. The length of side BC is a. The length of side AC is b and the length of side AB is c = 100

The sum of the angles in a triangle is 180 degrees. Therefore.

Angle A + angle B + angle C = 180. Therefore,

20 + 35 + angle C = 180

55 + angle C = 180

Angle C = 180 - 55 = 125 degrees. To determine the length if a, we would apply the sine rule which is expressed as

a/SinA = b/SinB = c/SinC

Therefore,

a/Sin20 = 100/Sin125

aSin125 = 100sin20

a × 0.8192 = 0.342 × 100

0.8192a = 34.2

a = 34.2/0.8192

a = 41.75

Approximately 42
