The depth of water at a dock can be modeled as y=4 sin( pi 6 x)+9. At low tide , the water is 5 feet deep. What is the depth of water at high tide its maximum point )?

your right the answer is A

have a good day (= <3 <3

Step-by-step explanation:

its 4 because 2 times 2 is 4, if you double the number two you get four

set each factor equal to 0

4x-3 = 0

2x-1 = 0

solve for x.

4x-3=0

4x=3

x= 3/4

solve for x. 

2x-1= 0

2x= 1

x= 1/2

eventually after a few more steps, your answer should be 1/2 is less than or equal to x and 3/4 is greater than or equal to x
