Actually, this has little to do with mathematics and geometry but has to do more with logical reasoning. You have two clauses to get a conclusion from. The reasoning is as follows:
Clause 1: <span>Three noncollinear points determine a plane
Clause 2: </span><span>Points S, O, N are noncollinear
</span>Conclusion: Therefore, points S, O and N form a plane.
The distance of A from the origin.
√(5²+3²+(-2)²)= √(25+9+4)
=√38
=6.2
The distance of B from the origin
√(2²+(-4)²+8²=√(4+16+64)
=√84
= 9.2
Answer:
3.2
Step-by-step explanation:
4 is in the hundredths place. It is less than 5 so you leave the tenths place alone, so you get 3.2.
I can't really see those. Sorry I can't help you
Answer:
The length of the road that runs straight from Pittsburgh to Jeanette is 29.8 miles
Step-by-step explanation:
We are given
Bethel Park is 28 miles directly west of Jeanette
10.3 miles directly south of Pittsburgh
We can draw diagram
we can see that this is triangle
so, we can use Pythagoras theorem
and we get
now, we can solve for x
So,
The length of the road that runs straight from Pittsburgh to Jeanette is 29.8 miles
