the formula for the speed of a tsunami in deep water is v=gh−−√ , where g is acceleration due to gravity, 9.8 m/s2 , and h is the depth of the ocean in meters. use this formula to estimate the speed at which the tsunami that started with an earthquake in sumatra struck sri lanka about 1550 km away. the bay of bengal is 4 km (4000 m) deep.

well if you have a decimal you have to line them up and make sure the you have everything   straight and then add or subtract some thing with   division and   multiplying so just like them up

step-by-step explanation:

any linear relation with finite slope (that is, something other than x=constant) will be a function with a domain and range of "all real numbers."

further, any odd-degree polynomial will likewise be a function with domain and range of "all real numbers." a linear equation is a polynomial of degree 1, hence of odd degree.
