Step-by-step explanation:
The diameter is the longest possible line through the sphere and passes through the center.
Answer:
133.04ft²
Step-by-step explanation:
Area of a circle is:

We are given the diameter. The radius of the given circle is 6. Note that the diameter is twice the radius.
Using 3.14 for pi:

The area is appropriately 133.04ft².
Hope this helps.
hey mate here is you answer..! ;)
Answer:
x = 3/2
Step-by-step explanation:
38x = 10x + 42
=>38x - 10x = 42
=>28x = 42
=>x = 3/2
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.



9 bc you can add all the numbers together then divide that by the total amount of numbers there were
