<span>Which kind of function best models the set of data points (–1, 22), (0, 6), (1, –10), (2, –26), and (3, –42)?
LINEAR. I arrived at that conclusion after solving for the slope.
m = y1 - y2 / x1 - x2
m = 22 - 6 / -1 - 0 = 16/-1 = -16
m = 6 - (-10) / 0 - 1 = 16/-1 = -16
m = -10 - (-26) / 1 -2 = 16/-1 = -16

Answer: 1.3 seconds
Step-by-step explanation:
Given: Distance of the moon to the Earth = 384,400 km = 384400 x 1000 meters = 384400000 meters. [1 km = 1000 m]
Speed of light =
m/s = 299800000 m/s
Formula: ![\text{Time}=\dfrac{\text{Distance}}{\text{Speed}}](https://tex.z-dn.net/?f=%5Ctext%7BTime%7D%3D%5Cdfrac%7B%5Ctext%7BDistance%7D%7D%7B%5Ctext%7BSpeed%7D%7D)
Let <em>t</em> be the time taken by the light to travel from the moon to the Earth.
![t=\dfrac{384400000}{299800000}\approx1.3\text{ seconds}](https://tex.z-dn.net/?f=t%3D%5Cdfrac%7B384400000%7D%7B299800000%7D%5Capprox1.3%5Ctext%7B%20seconds%7D)
Hence, it will take approximately 1.3 seconds for the light to travel from the moon to the Earth.

Answer:
2,784 lbs
Step-by-step explanation:
2900/100=29 (that is 1% of the 2900)
29*4=116 (that is 4% of 2900; how much weight they lost)
2900-116=2784 (current weight)
