Hi there your answer would be d
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.
What is 48.75 as a fraction?
To write 48.75 as a fraction you have to write 48.75 as numerator and put 1 as the denominator. Now you multiply numerator and denominator by 10 as long as you get in numerator the whole number.
48.75 = 48.75/1 = 487.5/10 = 4875/100
And finally we have:
48.75 as a fraction equals 4875/100
By definition, the linear velocity is given by:

Where,
w: angular speed
r: radius
We have that the radius of the wheel is

Where,
d: diameter of the wheel
substituting values:

Then, we have the following conversions:
1 revolution = 2π radians
1 minute = 60 seconds
Therefore, the angular velocity in radians per second is:

Substituting values we have:
Answer:
your linear velocity is:
a. 0.62 feet per second
Answer: x = 6.5
Step-by-step explanation:
