The path of a breaching ocra whale can be modeled by the function k(1) = 12 - 2t - 8, where is the time elapsed in seconds under water, and k( 1 ) is the height in ft below the
water
Determine HOW LONG is the oçra (killer) whale underwater to the nearest second.
MUST BE SOLVED ALGEBRAICALLY!

Which is a true statement comparing the graphs of x^2/6^2-y^2/8^2 = 1 and x^2/8^2-y^2/6^2 the foci of both graphs are the same points. the lengths of both transverse axes are the same. the directrices of = 1 are horizontal while the directrices of = 1 are vertical. the vertices of = 1 are on the y-axis while the vertices of = 1 are on the x-axis.

Which of these triangle pairs can be mapped to each other using two reflections?
