A table with four legs will sometimes wobble if one leg is shorter than the other three, but a table with three legs will not wo

bble. Select the postulate that substantiates this fact.
Postulate 1: A line contains at least two points.
Postulate 1a: A plane contains at least three points not all on one line.
Postulate 1b: Space contains at least four points not all on one plane.
Postulate 2: Through any two different points, exactly one line exists.
Postulate 3: Through any three points that are not one line, exactly one plane exists.
Postulate 4: If two points lie in a plane, the line containing them lies in that plane.
Postulate 5: If two planes intersect, then their intersection is a line.

Answer:

Postulate 3: Through any three points that are not one line, exactly one plane exists.

Step-by-step explanation:

Table with three legs will support the table equally since there exists a plane between the three legs of the table and the table will not wobble. It is analogy to the fact that three points not in one same line will exhibit one plane.

Thus the table will not shake and wobble because the plane which exists between the three legs will balance the table properly.

Thus, postulate 3 is the correct option for the proof.

The nth term of the sequence is given by the formula a subscript nanequals=​_______, where a 1a1 is the​ _______ and d is the​ _
salantis [7]
The formula is a subscript n = 6^n
Where a1 is the first term and d is the common difference of the sequence
Thus, the first term is 6, second term 36, then 216.....
thus the sequence is, 6, 36, 216, .....................
Therefore, this is a geometric sequence with a common difference of 6

A train from Portland, Oregon, to Los Angeles, California, travels at an average speed of 60 miles per hour and covers a distanc
seropon [69]

Answer:

The train need to leave Portland at 03:27 am

Step-by-step explanation:

step 1

Find out how long it takes the train to travel from Portland, Oregon, to Los Angeles, California

Remember that

The speed is equal to divide the distance by the time

so

The time is equal to divide the distance by the speed

Let

s ---> the speed in miles per hour

d ---> the distance in miles

t ---> the time in hours

t=\frac{d}{s}

we have

d=963\ mi

s=60\ mi/h

substitute

t=\frac{963}{60}=16.05\ hours

step 2

Adds 30 minutes (time it takes to get from the train station to her aunt's house)

Remember that

30\ minutes=0.50\ hours

16.05+0.50=16.55\ hours

Convert to minutes

16.55\ h=16.55(60)\ min=993\ min

step 3

Remember that

8 p.m=20:00\ hrs

Convert to minutes

20(60)=1,200\ min

Subtract 993 minutes from 1,200 minutes

1,200-993=207\ min

Convert to hours+minutes

207\ min=207/60=3.45\ hours

0.45\ h=0.45(60)=27\ min

so

3\ h+27\ min

00:00 + 03:27=03:27\ am

therefore

The train need to leave Portland at 03:27 am
