Answer:
The question is incomplete, the complete question is "Changing Bases to Evaluate Logarithms in Exercise, use the change-of-base formula and a calculator to evaluate the logarithm. See Example 9. .
Step-by-step explanation:
From the general properties or laws of logarithm, we have the
where both log are now express in the natural logarithm base.
i.e
hence we can express our .
the value of ln7 is 1.9459 and ln4 is 1.3863
Hence .

An exponential parent function is the option C. f(x)= , from the given options.
What do you mean by exponential parent function?
The formula for their parent function is y = , where b is any non zero constant. Below is a graph of the parent function, y =
, which demonstrates that it will never equal 0. And at y = 1 when x = 0, y crosses the y-axis.
According to options in the given question,
We have the option below in the given question:
A. f(x) = 2^x – 3 
B. f(x) = 2^x + 2 
C. f(x) = 2^x 
D. f(x) = 2^x + 1/3
We know from the above definition that the option C. is the right answer to the given question.
Therefore, the exponential parent function is f(x)= .

Answer:
4
Step-by-step explanation:
Given the following column vectors
(1, -2, 0), (-1, 3, 1), (2, 1, 5) and (-1, 1, 1)
Before we can get the dimension of the vector, the following steps must be followed;
Step 1:
We need to transform the vectors given into a matrix form and then reduce the resulting matrix.
Step 2:
Then we generated the basis of the matrix (new set of column vectors from the reduced matrix).
Step3:
The total number of column vectors generated will be equivalent to the dimension of the vectors.
The dimension spanned by the set of vectors is 4
