Answer:
-v
Step-by-step explanation:
The opposite vector is the vector that has the same magnitude of the original vector but points in opposite direction.So the vector -v has the same magnitude as the vector v but points to the opposite direction. Vector -v will start from the point 6 and will end at the point 3.That is opposite of the vector v which starts from point 3 and ends at point 6.
Hence the answer is -v.
Answer:
22
Step-by-step explanation:
If there are n children, the number of candies in the first distribution is ...
3n +1
If the same number of candies is distributed to the same n children, then the second distribution tells us ...
2n +8 = 3n +1
7 = n . . . . . . . . . subtract 2n+1. This is the number of children.
The number of candies is ...
3(7) +1 = 22
There were 22 candies in total.
The pH of the substance is 3.
<u>Explanation:</u>
Given:
Concentration of hydrogen ion, [H⁺] = 10⁻³M
pH = ?
The pH of a solution is a measure of the molar concentration of hydrogen ions in the solution and as such is a measure of the acidity or basicity of the solution.
pH = -log [H⁺]
pH = -log [10⁻³]
pH = 3 log [10]
pH = 3
The pH of the substance is 3 and since the pH is less than 7, the substance is acidic in nature.
Answer:
SSS Theorem
Step-by-step explanation:
All the corresponding sides of these two triangles are of equal length, proving their congruency. Although it can be assumed that they also share the same angles, no angle information is directly given to prove the fact.
