The function f(t) = 7 cos(pi over 4t) + 12 represents the tide in light sea. it has a maximum of 19 feet when time (t) is 0 and a minimum of 5 feet. the sea repeats this cycle every 8 hours. after two hours, how high is the tide?

The function f(t) = 7 cos(pi over 4t) + 12 represents the tide in Light Sea. It has a maximum of 19 feet when time (t) is 0 and a minimum of 5 feet. The sea repeats this cycle every 8 hours

To find the height of the tide after 2 hours, we plug in 2 for t  and find out f(2)

We know that cos (pi/2) is 0

So f(2)= 12

After two hours, the height of the tide is 12 feet

60

step-by-step explanation:

every triangle measures a total of 120 degrees. you have to find angle c. we know that isosceles triangles angles are equal. 60 degrees plus 60 degrees gives you 120.
