All you do for #4 and # 5 is plug the x values FROM THE TABLE into the equation, and see if you get the y values listed in the table. You don't, so you can see that the equations DO NOT REPRESENT THE DATA IN THE TABLE. For #6 you can see from the graph that one point on the line is (1,-2) which does represent the table of values. Looking further, as each x value decreases by 1, the y value decreases by 3, so (0,-5) makes sense too, again supporting the idea that the graph DOES represent the table of values
Answer:
Step-by-step explanation:
We have to determine which trigonometric ratio to use, depending on what is displayed for us, and we will be using the <em>cotangent</em><em> </em>[or <em>tangent</em>] ratio, however, aside we are solving for an <em>angle</em><em> </em><em>measure</em>, we must use the inverse:

Answer:
216 mi/h
Step-by-step explanation:
The time for the trip with the wind is ...
(1080 mi)/(225 +45 mi/h) = 4 h
The time for the trip against the wind is ...
(1080 mi)/(225 -45 mi/h) = 6 h
The average speed for the entire round trip is ...
(2160 mi)/(4 +6 h) = 216 mi/h
Answer:
Here the answer LOL
Step-by-step explanation:
1908 Siberian Asteroid is known to be 130 feet/ 18 meters in
diameter while on the other hand Chelyabinsk Asteroid is known to be 59 feet/40
meters in diameter. To find how many times Siberian Asteroid is bigger than
Chelyabinsk Asteroid we just have to divide Siberian by Chelyabinsk here we
get:
10/59=2.2 = 1908 Siberian Asteroid is 2.2 times bigger than
Chelyabinsk Asteroid.
