Answer:
B. 12
Step-by-step explanation:
SO 2/3 of 18 is basically saying multiply them together
Every time you see the word “of” Basically means multiply.
23*18=12
Answer:
The answer is 165 in.
Step-by-step explanation:
The first shape (On the right) has a length of 3in. If you look at the top. and the height is 9in. Now you can find the width by looking at the other shape on the left and its width is 3in. Good thing the width on that shape matches the width on the right shape. so now you multiply 3, 3, and 9 and you get 81.
Now you look at the shape on the left. We already know the width which is 3in. and the height is 4in. to find the length don't look at the 10in. the 10 is the 1st and 2nd shape put together. look at the top of the shape on the left and there is a 7. That 7 is your length. now you multiply 7, 3, and 4 and you should get 84. Now you add 84 and 81 and you are left with the answer of 165in squared.
Answer: -1/2
Step-by-step explanation:
The average rate of change is 
. Since a=-1 and b=1. We can plug them into the equation and solve.
![\frac{[1^2-1-1][(-1)^2-(-1)-1)]}{1-(-1)} =\frac{(-1)(1)}{2} =-\frac{1}{2}](https://tex.z-dn.net/?f=%5Cfrac%7B%5B1%5E2-1-1%5D%5B%28-1%29%5E2-%28-1%29-1%29%5D%7D%7B1-%28-1%29%7D%20%3D%5Cfrac%7B%28-1%29%281%29%7D%7B2%7D%20%3D-%5Cfrac%7B1%7D%7B2%7D)
Answer:
symmetric matrix is the square matrix and it is equal to its transpose
Step-by-step explanation:
solution
a symmetric matrix is the square matrix and it is equal to its transpose
As A is symmetric matrix then
A = 
here only square matrices will be symmetric
and matrix A is symmetric its mean its matrices have equal dimension
and every square diagonal matrix is also symmetric when all off diagonals element is zero
symmetric matrix for all indices i and j
A = aij = aji
