√-45 = √45(-1) = √45 * √-1 = 5√9 * √-1 = 15i
Remember, i = √-1
Answer:
Limit
does not exist.
Step-by-step explanation:
To calculate left hand limit, we use a value slightly lesser than that of 0.
To calculate right hand limit, we use a value slightly greater than that of 0.
Let h be a very small value.
Left hand limit will be calculate at 0-h
Right hand limit will be calculate at 0+h
First of all, let us have a look at the value of f(0-h) and f(0+h)




Now, left hand limit:
= 

Using equation (1):
= -1
Now, Right hand limit:
= 

Using equation (2):
= 1
Since Left Hand Limit
Right Hand Limit
So, the answer is:
Limit
does not exist.
Answer:
<h2>The answer is 5 units</h2>
Step-by-step explanation:
The distance between two points can be found by using the formula

where
(x1 , y1) and (x2 , y2) are the points
From the question
The points are (9,-7) and (5, -4)
The distance between them is

We have the final answer as
<h3>5 units</h3>

Her salary 4 years ago would have been $30,000.
If 45,000 is 15,000 less than double her previous salary, we must first add 15,000 to 45,000 to find what double her salary was.
45,000+15,000=60,000.
Since this is twice her salary, we divide this by 2.
60,000/2= 30,000.
So, her salary 4 years ago would have been $30,000.
I hope this helps!
Answer:
-5
Step-by-step explanation:
First, put the equation into the form y = mx +b (where m is the slope and b is the y-intercept)
This would look like:

This means the slope is -5.
Parallel lines always have the same slope, so the slope of the parallel line is also -5
