In steinhatchee in july, high tide is at noon. the water level is 5 feet at high tide and 1 foot at low tide. assuming the next high tide is exactly 12 hours later and the height of the water can be modeled by a cosine curve, find an equation for steinhatchee's water level in july as a function of time (t). f(t) = 6 cos pi over 2 t + 2 f(t) = 2 cos pi over 2 t + 3 f(t) = 2 cos pi over 6 t + 3 f(t) = 6 cos pi over 6 t + 2

Part a what is the area of triangle i? show your calculation. part b triangles i and ii are congruent (of the same size and shape). what is the total area of triangles i and ii? show your calculation. part c what is the area of rectangle i? show your calculation. part d what is the area of rectangle ii? show your calculation. part e rectangles i and iii have the same size and shape. what is the total area of rectangles i and iii? show your calculation. part f what is the total area of all the rectangles? show your calculation. part g what areas do you need to know to find the surface area of the prism? part h what is the surface area of the prism? show your calculation. part i read this statement: “if you multiply the area of one rectangle in the figure by 3, you’ll get the total area of the rectangles.” is this statement true or false? why? part j read this statement: “if you multiply the area of one triangle in the figure by 2, you’ll get the total area of the triangles.” is this statement true or false? why?
