Answer:
Area= 19.63 units squared Circumference= 15.71 units
Step-by-step explanation:
Area= π r ^2
Circumference= 2π r
Answer:
The resultant velocity will be 12m/s
Step-by-step explanation:
If the river flows downstream at 2m/s and also the boat is heading downstream at 10m/s. You can add the two velocities to get the resultant velocity:
Resultant Velocity = 10 m/s + 2 m/s = 12 m/s.
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:
Answer:
2
Step-by-step explanation:
Copy 1 is a scaled copy of the original triangle. The scale factor is 2, because each side in Copy 1 is twice as long as the corresponding side in the original triangle. , , Copy 2 is a scaled copy of the original triangle.
