(x,y) = (0,0) x=0 y=0 I would use the elimination method. hope this helped
Answer:
70 m/s
Step-by-step explanation:
<u>"The speed of a tidal wave in meters/second is given by the square root of the product of the acceleration due to gravity on Earth (9.8 meters/second2) and the depth of the ocean in meters":</u>
The sentence above can be interpreted into the equation shown below (letting speed of tidal wave be "s", acceleration due to gravity be "g", and depth be "d"):

<em><u>Given d = 500 and g = 9.8, we find speed (s):</u></em>

Hence, the speed is 70 meters per second.
To convert 45000 inches into miles first you have to find out how much is miles to inches then divide you should 0.4500
