In the diagram, the lines ℓ and m appear to be parallel. How do you know for sure? Use the diagram to complete Questions a – c. a. Given that the sum of the measures of the angles in a triangle is 180º,
solve for x.
b. Find the measure of each angle of △ABC.
c. Explain why ℓ ∥ m.

Why don't you see your reflection in water with waves or repples

If a rock is thrown upward on the planet mars with a velocity of 12 m/s, its height (in meters) after t seconds is given by h = 12t − 1.86t2. (a) find the velocity of the rock after two seconds. m/s (b) find the velocity of the rock when t = a. 12−3.72a m/s (c) when will the rock hit the surface? (round your answer to one decimal place.) t = s (d) with what velocity will the rock hit the surface? m/s

(1 point) match the differential equations and their vector valued function solutions. you may wish to multiply at least one solution out fully, to make sure that you know how to do it. you can get the other answers quickly by process of elimination and just multiply out one row element.
