Answer:
The base (b) has to be positive and different of 1. The logarithm is the inverse of exponential, so:
logb(a) = x ⇒ a = bˣ
So, for b = 0 ⇒ 0ˣ = a
And there is impossible, "a" only could be 0.
For b = 1 ⇒ 1ˣ = a
And the same thing would happen, the logarithming would be to be 1, and the function will be extremally restricted.
For b<0, then the expression a = bˣ will be also restricted, and will not represent all values of a.
So, 0<b<1 and b >1.
Answer:
Each of the 7 friends could be present or not present (2 cases) at the party giving total of 27 scenarios.
Since at least one must be present we exclude the case that none of them is present. So the answer would be:
27−1=127.
Step-by-step explanation:
i actually dont know but can you report me and dont ask
1 hour = 60 minutes
27/60 = 0.45 miles per minute
Answer:

Step-by-step explanation:
we know that
The equation of the line in slope intercept form is equal to

where
m is the slope
b is the y-intercept
so
1) Find the slope of the given line 
The slope is 
2) Find the y-intercept of the given line 
The y-intercept is 
therefore
The equation of the line with


is equal to

The dimensions of the matrix are 3 by 3 i.e. 3 x 3, and the indicated element a₂₃ is -7
<h3>The dimension of the matrix?</h3>
From the figure in the question, we have the following highlights:
- The matrix has 3 rows
- The matrix has 3 columns
The dimensions of a matrix are represented by: Row by column
Hence, the dimensions of the matrix are 3 by 3
<h3>The indicated element</h3>
This is given as:
a₂₃
This means that the element is located at the second row and the third column.
The element at this position is -7
Hence, the indicated element is -7
