Answer:
Point form : (- 2/3, 10/9)
Equation form : x=- 2/3, y=10/9
Step-by-step explanation: Solve for the first variable in one of the equations, then substitute the result into the other equation.
I hope this helps you out. :)
So hmmm check the graph below
now.. to find the vertex of any quadratic
so... how long did it take? well, it took
what was the highest point? well, it was
when did he hit the water? well, at y = 0
that is
solve for "t"
Answer:
-2
Step-by-step explanation:
Since they are parallel, they have the same slope. This will be true for any set of lines.
ANSWER:
We have to find new side-lengths of PQR triangle.
Original sides are.
After multiplying by 2.5 we get
These are the new sides of the P'Q'R' triangle.
Beautiful ! What a great exercise ! I won't even check to verify
that 1:10⁻¹⁹ is an appropriate scale to map the Milky Way onto a
football field. I'll just accept it and go from there.
(4.4 light years) x (10⁻¹⁹) = (2.5848 x 10¹³ miles) x (10⁻¹⁹)
= 2.5848 x 10⁻⁶ mile
= 0.164 inch .
(1,391,400 kilometers) x (10⁻¹⁹) = 1.3914 x 10⁻¹⁰ meter
Research Conclusions:
If the Milky Way shrinks to fit on a football field, then
-- Alpha Centauri is 0.164 inch from us.
-- The sun's diameter is about 1.39 times that of a Hydrogen atom.
Playing with this same fun concept a little more:
-- The Earth is sailing around in its orbit, once a year,
about 0.000015 millimeter from the sun.
-- It takes light almost 27 years to travel 1 inch !
wow !
