(A)
we are given
(-1.15) x 3.2
Since, sign of 1.15 is negative
and sign of 3.2 is positive
so, we put negative sign in front
now, we can multiply them
and we get
.............Answer
(B)
Suppose, we are given product of two numbers 'a' and 'b'
so, we use this property
case-1: When both positive , then we put positive in front
case-2: When both negative , then we put positive in front
case-3: When first is negative and second is positive , then we put negative in front
case-4: When first is positive and second is negative , then we put negative in front
Answer:
Linearly Dependent for not all scalars are null.
Step-by-step explanation:
Hi there!
1)When we have vectors like we call them linearly dependent if we have scalars
as scalar coefficients of those vectors, and not all are null and their sum is equal to zero.
When all scalar coefficients are equal to zero, we can call them linearly independent
2) Now let's examine the Matrix given:
So each column of this Matrix is a vector. So we can write them as:
Or
Now let's rewrite it as a system of equations:
2.1) Since we want to try whether they are linearly independent, or dependent we'll rewrite as a Linear system so that we can find their scalar coefficients, whether all or not all are null.
Using the Gaussian Elimination Method, augmenting the matrix, then proceeding the calculations, we can see that not all scalars are equal to zero. Then it is Linearly Dependent.
