The depth of water at a dock can be modeled as y 4 sin (pi/6 x) + 7. At low
tide, the water is 3 feet deep. What is the depth of water at high tide (its
maximum point)?
O A. 10 feet
O B. 11 feet
O C. 7 feet
O D. 14 feet

Respuesta :

Answer:

11

Step-by-step explanation:

The depth of water at high tide at a maximum point is 11 feet.

option (A) is correct.

What is trigonometry?

Trigonometry is a branch of mathematics that deals with the relationship between sides and angles of a right-angle triangle.

We have a trigonometric function:

y= 4 sin(π/6x)+7

As, the range value of a sin function varies [-1, 1].

At minimum value = -1

So, depth of the water y = -4 + 7 = 3 feet

At maximum value, = +1

y = 4 + 7

y = 11 feet

Hence, the depth of water at high tide at a maximum point is 11 feet
