Answer:
-4< (with line underneath) x <(with line underneath) 4
Step-by-step explanation:
Answer:
Step-by-step explanation:
Parallel slope = -8
Perpendicular slope = 1/8
Range is the highest value minus the lowest value
Given the equation:
You know that a lab technician finds that a sample of fluid has this pH:
Then, in order to find the hydrogen ion concentration of the fluid, you need to follow these steps:
1. Substitute the pH given in the exercise into the equation:
Multiply both sides by -1:
2. Solve for:
Remember that, by definition:
In this case, you can identify that:
Hence, substituting values and simplifying, you get:
Therefore, the answer is:
Its pretty simple.
72 divided by 8= 9
A. 9
Then you just Multiple 9•4=36
B. 36
