Lara is trying to solve a puzzle where she has to figure out two numbers, x and y. Five times x is greater than or equal to 3 mo

re than y. Also, 1 more than 4 times y is greater than twice x. Which graph represents the possible solutions? Graph the inequalities 5 x plus y greater than or equal to 3 and 2 x plus 4 y less than 1 Graph the inequalities 5 x minus y greater than or equal to 3 and 2 x minus 4 y less than 1 Graph the inequalities x plus 5 y greater than or equal to 3 and 4 x plus 2 y less than 1 Graph the inequalities x minus 5 y greater than or equal to 3 and 4 x minus 2 y less than 1

Qualify for free shipping. Earthen red clay costs $0.75
per pound, and porcelain white clay costs $1.10
per pound.

To summarize the situation, the artist writes the inequality:

0.75r+1.1w≥100
, where r
is the number of pounds of earthen red clay, and w
is the number of pounds of porcelain white clay.

Which graph's shaded region shows the possible combinations of earthen red clay and porcelain white clay the artist can buy to qualify for free shipping?

The notation Ak meas the matrix A Multiplied with itself k times (a) For the 2×2 identity matrix I, show that I2 =I (b)For the n
djverab [1.8K]

Answer:

Entries of I^k are are also identity elements.

Step-by-step explanation:

a) For the 2×2 identity matrix I, show that I² =I

I^{2}=\left[\begin{array}{cc}1&0\\0&1\end{array}\right] \times \left[\begin{array}{cc}1&0\\0&1\end{array}\right] \\\\=\left[\begin{array}{cc}1\times 1+0\times 0&1\times 0+0\times 1\\0\times 1+1\times 0&0\times 0+1\times1\end{array}\right] \\\\=\left[\begin{array}{cc}1&0\\0&1\end{array}\right]

Hence proved  I² =I

b) For the n×n identity matrix I, show that I² =I

n×n identity matrix is as shown in figure

Elements of identity matrix are

\delta I_{ij}=1\quad if\quad i=j\\\delta I_{ij}=0\quad if\quad i\ne j\\

As square of 1 is equal to 1 so for n×n identity matrix I, I² =I

(c) what do you think the enteries of Ik are?

As mentioned above

\delta I_{ij}=1\quad if\quad i=j\\\delta I_{ij}=0\quad if\quad i\ne j\\

Any power of 1 is equal to 1 so kth power of 1 is also 1. According to this Ik=I
