What wheres is this a troll lol
Answer:14.8
Step-by-step:
Use the equation a^2+b^2=c^2
Plug in 13 for a and 7 for b
13^2+7^2=c^2
Multiply the number by themselves
13•13+7•7=c^2
169+49=c^2
218=c^2
Square root both side
14.76=c
Round the nearest tenth
14.8
Answer:
Step-by-step explanation:
Recall that an elementary matrix of a matrix operation is obtained by applying the matrix operation to the identity matrix. In this case, by replacement, it means changing the whole row of a matrix and replacing it with a the same row multiplied by a number k.
In this case, the solution is
What is the determinant of an elementary row replacement matrix?
An elementary n xn row replacement matrix is the same as the n x n identity matrix with Exactly one of the 1's replaced with some number k.This means this is the triangular matrix and so its determinent is product of its diagonal entries. Thus, the determinant of an elementary row replacement matrix is a number. Especifically, the number k we used to replace the one
1. Exactly one,atleast one
2. 1's or 0's
3. Identity matrix,invertible matrix, triangular matrix or zero matrix.
4. Product or sum
5. A number
Answer:
1)2x^2 2)8x^3 3)4x-8
Step-by-step explanation:
1- you plug in x in g but nothing changes so then h and gyou just add 2- you plug in x in g again but once again, it remains the same so you just multiphy g and h and you get 8x^2 3- you plug in -2 into g to get 8 and then subtract it form h
The answer is C. 16.5 m^2.
