Answer:
Amanda's popcorn container holds more popcorn
Step-by-step explanation:
<em><u>First we'll have to find the volume.</u></em>
The Volume helps us determine which is bigger.
<em><u>Step 1</u></em>
We'll find Amanda's popcorn container
10cm*10cm*13.5cm=1350cm
<em><u>Step 2</u></em>
We'll find Mary's popcorn container
8cm*8cm*20cm=320cm
<em><u>Step 3</u></em>
Since Amanda's popcorn container has 1350cm (volume) and Mary's popcorn container has 320cm (volume) we'll have this. 1350cm>320cm. We can determine the Amanda's popcorn container has holds more,
<em><u>Final Answer</u></em>
Amanda's popcorn container holds more popcorn
Let's consider an arbitrary 2x2 matrix as an example,
The columns of
are linearly independent if and only if the column vectors
are linearly independent.
This is the case if the only way we can make a linear combination of
reduce to the zero vector is to multiply the vectors by 0; that is,
only by letting
.
A more concrete example: suppose
Here,
and
. Notice that we can get the zero vector by taking
and
:
so the columns of
are not linearly independent, or linearly dependent.
I'm doing the same thing right now and I'm lost.
Add 4x over to 14x, 3=5x2- 18x then add 18x to the other side 3+ 18x= 5x2then divided each side by 5,( 3+18x/5=x2) then square root each side the answer to x would be the square root of 3+18x/5
5+(x-5)=x
Simplify the left side by combining like terms:
5 + x - 5 = x
5-5 = 0
x = x
X = All real numbers.
