Answer:
a = 1/64
Step-by-step explanation:
3 + 4 a ^ 1/6 = 5
1. move constant to the right side and change its sign
4 a ^ 1/6 = 5 - 3
2. using <em>a</em><em> </em><em>^</em><em> </em><em>m/</em><em>n</em><em> </em><em>=</em><em> </em><em>n√a^m</em><em> </em><em> </em>transform the expression
4 6√a = 5 - 3
3. Subtract the numbers
4 6√a = 2
4. Divide both sides of the equation by 4
6√a = 1/2
5. Raise both sides of the equation to the power of 6.
a = 1/64
Answer:
18) A: only if you have an additional point not on the line.
19) D: No, because all the points may be on the same line.
Step-by-step explanation:
There are basically 4 ways we can determine a plane and they are;
- When we have three non - collinear points: What this means is that if we have three points that are not on one line, then it means that only one particular plane can pass through those points.
- When we have a line and a point that's not on the line
- When we have two lines that intersect each other.
- When we have two lines that are parallel to each other.
From the four conditions above, we can now answer the question;
18) You can only have a plane if there is an additional point not on the line.
Option A
19) Having just three points may not always be sufficient to have a plane because it's possible that the three points may be on the same line which is not a condition for a plane. Thus, option D is correct.
