What is the determinant of an elementary row replacement matrix?
Ludmilka [50]

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

Please help.
kirill115 [55]

we have

y=-16t^{2} +120

we know that

When the apple hit the ground the value of y is equal to zero

so

Find the x-intercept of the function

equate the function to zero

-16t^{2} +120=0

Group terms that contain the same variable, and move the constant to the opposite side of the equation

-16t^{2} =-120

t^{2} =-120/-16

t^{2} =7.5

t=(+/-)\sqrt{7.5}

t=(+/-)2.74

therefore

<u>the answer is</u>

2.74\ sec

using a graphing tool

see the attached figure to better understand the problem
