Consider the function represented by the equation 6q = 3s - 9. Write the equation in function notation, where q is the independe
Tom [10]

Answer:  The correct option is (B) f(q) = 2q + 3.

Step-by-step explanation:  The given equation representing a function is

6q=3s-9~~~~~~~~~~~~(i)

We are to write the equation in function notation with 'q' as independent variable.

From equation (i), we have

6q=3s-9\\\\\Rightarrow 3s=6q+9\\\\\Rightarrow s=2q+3.

So, 's' can be represented as a function of 'q'. Hence, we can write

s=f(q).

Therefore, we have

f(q)=2q+3.

Thus, (B) is the correct option.

T had 53,790 miles onit. They had the car for 8.25 years. On average, how many miles did they drive per year?
liq [111]

Answer: ‭6,520‬ miles per year

Step-by-step explanation:

They had driven the car for 53,790 miles in 8.25 years.

The average number of number of miles driven per year is:

= 53,790 / 8.25 years

= ‭6,520‬ miles per year

<em>They drove an average of ‭6,520‬ miles per year.</em>

Determine whether the set of vectors is a basis for ℛ3. Given the set of vectors , decide which of the following statements is t
schepotkina [342]

Answer:

(A) Set A is linearly independent and spans R^3. Set is a basis for R^3.

Step-by-Step Explanation

<u>Definition (Linear Independence)</u>

A set of vectors is said to be linearly independent if at least one of the vectors can be written as a linear combination of the others. The identity matrix is linearly independent.

<u>Definition (Span of a Set of Vectors)</u>

The Span of a set of vectors is the set of all linear combinations of the vectors.

<u>Definition (A Basis of a Subspace).</u>

A subset B of a vector space V is called a basis if: (1)B is linearly independent, and; (2) B is a spanning set of V.

Given the set of vectors  A= \left(\begin{array}{[c][c][c][c]}1 & 0 & 0 & 0\\ 0 & 1 & 0 & 1\\ 0 & 0 & 1 & 1\end{array} \right) , we are to decide which of the given statements is true:

In Matrix A= \left(\begin{array}{[c][c][c][c]}(1) & 0 & 0 & 0\\ 0 & (1) & 0 & 1\\ 0 & 0 & (1) & 1\end{array} \right) , the circled numbers are the pivots. There are 3 pivots in this case. By the theorem that The Row Rank=Column Rank of a Matrix, the column rank of A is 3. Thus there are 3 linearly independent columns of A and one linearly dependent column. R^3 has a dimension of 3, thus any 3 linearly independent vectors will span it. We conclude thus that the columns of A spans R^3.

Therefore Set A is linearly independent and spans R^3. Thus it is basis for R^3.
