If you divide all of them together starting inside of the parentheses you will get the wrong answer bc I’m just typing random thing
The top row of matrix A (1, 2, 1) is multiplied with the first column of matrix B (1,0,-1) and the result is 1x1 + 2x0 + 1x -1 = 0 this is row 1 column 1 of the resultant matrix
The top row of matrix A (1,2,1) is multiplied with the second column of matrix B (-1, -1, 1) and the result is 1 x-1 + 2 x -1 + 1 x 1 = -2 , this is row 1 column 2 of the resultant matrix
Repeat with the second row of matrix A (-1,-1.-2) x (1,0,-1) = 1 this is row 2 column 1 of the resultant matrix, multiply the second row of A (-1,-1,-2) x (-1,-1,1) = 0, this is row 2 column 2 of the resultant
Repeat with the third row of matrix A( -1,1,-2) x (1,0, -1) = 1, this is row 3 column 1 of the resultant
the third row of A (-1,1,-2) x( -1,-1,1) = -2, this is row 3 column 2 of the resultant matrix
Matrix AB ( 0,-2/1,0/1,-2)
E. They will be equally dark because when all of those fractions are simplified they equal 1/3
Answer:
r = 12 millimeters
Step-by-step explanation:
Surface area of a ball = 4πr²
Surface area of a ball = 576 pi square millimeters
Surface area of a ball = 4πr²
576π = 4πr²
r² = 576π / 4π
r² = 144
Find the square root of both sides
√r² = √144
r = 12
r = 12 millimeters
Answer:
<em>10000 times as much</em>
Step-by-step explanation:
If we were to determine how many times larger it is, we can simply divide the two expressions;
5 × 10^6 / 5 × 10^2,
10^6 / 10^2,
10^6 - 2,
10^4; <em>Answer : 10^4 times as much; in other words 10000 times as much</em>
