The answer is D=M/V I hope I helped :)
Answer:
3ft by 6ft
Step-by-step explanation:
Area = l*w
P = 2(l+w)
We know that the area is the same as the perimeter
2 (l+w) = 18
Divide each side by 2
l+w =9
Our choices our 1,9
2,8
3,6
4,5
we know that they have to multiply to 18
1*9 =9
2,8 = 16
3,6=18
4,5=20
They only choice is 3 by 6
The volume of a cube can be found by cubing the side length. So, since 7 cubed is 343, the answer would either be c or d. Then, since the unit for volume is units cubed, the answer is D.
Answer:
C. T is not one-to-one because the standard matrix A has a free variable.
Step-by-step explanation:
Given
Required
Determine if it is linear or onto
Represent the above as a matrix.
From the above matrix, we observe that the matrix does not have a pivot in every column.
This means that the column are not linearly independent, & it has a free variable and as such T is not one-on-one
