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
<em><u>x>23 is the correct answer.</u></em> First you had to subtract by 3 from both sides of equation. And it gave us, . Then simplify, and it gave us,
. Next, multiply by 2 from both sides of equation, and it gave us,
. Then simplify, and it gave us,
. You can also subtract by 3 from both sides of equation, and it gave us,
. Then simplify, and it gave us,
. Multiply by -1 from both sides of equation, and it gave us,
. Finally simplify, and it gave us the answer is<u><em> x>23 is the right answer. </em></u>Hope this helps! And thank you for posting your question at here on brainly, and have a great day. -Charlie
