Given matrices S and T below, which statement is true?
harina [27]
The matrices are
S =(4 11                           T= ( -8 11
      -3  -8)                                 3  4 )
Inverse of a matrix is a matrix derived from another matrix such that if you pre- multiply it with the original matrix you get a unit matrix.
if we multiply S and T
 ST will be 
        ( 4 11    ×      (-8 11   = ( 1 0
          -3 -8)           -3 -4)         0 1)
and also TS
          ( -8 11      ×     (4 11  = ( 1 0
             -3 -4)            -3 -8)       0 1)
therefore, matrices S and T are inverses of each other because ST = TS= I

NEED HELP ASAP 20POINTS The energy (and cost) needed to operate an air conditioner is proportional to the volume of a space that
insens350 [35]

Answer:

The daily cost of cooling the large warehouse with the same model of air conditioner is \$1,953

Step-by-step explanation:

we know that

If two figures are similar, then the ratio of its volumes is equal to the scale factor elevated to the cube

In this problem

The scale factor is equal to 2.5

so

The scale factor elevated to the cube is 2.5^{3} =15.625

To estimate the daily cost of cooling the large warehouse with the same model of air conditioner, multiply $125.00 by the scale factor elevated to the cube

so

\$125(15.625)=\$1,953

<u>B. The interquartile range (IQR) for town A, 20, is greater than the</u>

<u>IQR for town B, 10.</u>

Step-by-step explanation:

IQR = Q₃ - Q₁

For the town A:

Q₃ = 40  and Q₁ = 20

IQR of town A = 40 - 20 = 20

For the town B:

Q₃ = 30   and Q₁ = 20

IQR of town A = 30 - 20 = 10

Check the given options:

The most statement is appropriate comparison of the spreads is B

it took heather 2/3 of an hour to read 20 pages in her library book. how long did it take her to read one page
NNADVOKAT [17]
2/3 hour .      1 hour = 60 minutes.

2/3 hour = (2/3) * 60

               = 40 minutes.

20 pages took  (2/3) hour = 40 minutes.

20 pages took her 40 minutes to read.

1 page = 40/20 = 2 minutes.

1 page took her 2 minutes to read.
