Answer:
speed of light is 3 x 
meters per second.
Step-by-step explanation:
Given : The speed of light is 3 x 
kilometers per second.
To find : What is that in standard form.
Solution : We have given 3 x kilometers per second.
First we convert it in to meter per sec.
We can write
3 x = 300000 kilometer per second .
We know that 1 km = 1000 meter.
Then 300000000 meter per second
Now, 3 x meter per second.
Therefore, speed of light is 3 x meters per second.
Answer:
11π/4 (radians) or 495° (degrees)
Step-by-step explanation:
Convert 165° to radians:
165 * π/180 = 165π/180 = <em>11π/12</em>
s = r/Ф
arc length = 3(11π/12) = 33π/12 = 11π/4
Convert back to degrees if asked to:
11π/4 * 180/π = 495° (Note that this is 165° * 3, see the pattern?)
( - 5 x² + 8 x ) + ( 2 x² - 3 x + 7)
= - 5 x² + 8 x + 2 x² - 3 x + 7
= - 3 x² + 5 x + 7

Answer:
Step-by-step explanation:
Hi there!
The two angles given are opposite angles, meaning that they are angles opposite of each other at an intersection.
Opposite angles are always equal:
Combine like terms:
Divide both sides by 6 to isolate <em>x</em>:
I hope this helps!
