Which values are solutions to the inequality below x2<100

1 answer:

5 0

$x^2 \ \textless \ 100\iff\sqrt{x^2} \ \textless \ \sqrt{100}\\\\|x| \ \textless \ 10\iff \boxed{x \ \textless \ 10\ \wedge\ x \ \textgreater \ -10}\\\\x\in(-10;\ 10)$

Which angles are a linear pair

8090 [49]

Two angles are said to be linear if they are adjacent angles formed by two intersecting lines. The measure of a straight angle is 180 degrees, so a linear pair of angles must add up to 180 degrees.

$\mathbf A=\begin{bmatrix}a_{1,1}&a_{1,2}\\a_{2,1}&a_{2,2}\end{bmatrix}$

$a_{i,j}=2i-j\implies\mathbf A=\begin{bmatrix}2\cdot1-1&2\cdot1-2\\2\cdot2-1&2\cdot2-2\end{bmatrix}=\begin{bmatrix}1&0\\3&2\end{bmatrix}$

Por la misma razón,

$\mathbf B=\begin{bmatrix}1-1&2-1\\1-2&2-2\end{bmatrix}=\begin{bmatrix}0&1\\-1&0\end{bmatrix}$

Entonces,

$4\mathbf A=\begin{bmatrix}4\cdot1&4\cdot0\\4\cdot3&4\cdot2\end{bmatrix}=\begin{bmatrix}4&0\\12&8\end{bmatrix}$

$\mathbf A-\mathbf B=\begin{bmatrix}1&0\\3&2\end{bmatrix}-\begin{bmatrix}0&1\\-1&0\end{bmatrix}=\begin{bmatrix}1-0&0-1\\3-(-1)&2-0\end{bmatrix}=\begin{bmatrix}1&-1\\4&2\end{bmatrix}$

$\mathbf B^\top=(b_{j,i})_{2\times2}=\begin{bmatrix}b_{1,1}&b_{2,1}\\b_{1,2}&b_{2,2}\end{bmatrix}=\begin{bmatrix}0&-1\\1&0\end{bmatrix}$

Yo no reconozco la notación "Ae"... Puedes explicarla?

$a_{1,1}\cdot b_{1,1}=1\cdot0=0$

$a_{2,2}\cdot b_{1,2}=2\cdot1=2$

A game is played with a fair spinner. 1,3,4,7 The spinner is spun twice and the two numbers are added to make a score. complete

SSSSS [86.1K]

We’ll use probability to answer this question.

Probability: Number of even numbers / All numbers added together.

Odd numbers: 1,3,7
Even numbers: 4

All numbers added together (amount of numbers not the numbers itself!) = 4

Amount of even numbers = 1

Probability of getting an even number is 1/4

Answer: Yes she is correct, the probability of getting an even number is 1/4.
