The depth of water near a boat dock is collected by a buoy. The data shows that the water level reached 11 feet during high tide

at 2:00am and a level of 8 feet during low tide at 9:00am. The depth can be modeled by a sinusoidal function. How deep will the water be at noon? Round your answer to the nearest hundredth. HINT: The equation that models this is y=1.5sin (25.72(x+1.5))+9.5

Answer:

  9.17 ft

Step-by-step explanation:

Put x=12 in the equation and evaluate. (The sine argument is in degrees.)

  y = 1.5·sin(25.72(12 +1.5)) +9.5 = 1.5·sin(347.22) +9.5

  y = -0.33 +9.5 = 9.17

The water will be 9.17 feet deep at noon.

Similfy 1/2 (30x + 4y - 14 ) +1/4 (16x - 28y + 4)
Hoochie [10]

Answer:

19x - 5y - 6

Hope this helped

Step-by-step explanation:

You start by simplifying each expression, you will be distributing the number outside the parentheses  on each number inside the parentheses

1/2(30x+4y-14)

1/4(16x -28 +4)

leaving you with

15x + 2y - 7 + 4x - 7y + 1

combine the x's y's and the singular numbers

19x - 5y - 6

Given the graph below write the equation of the line.
Scrat [10]

Answer:

y = 2x+8

Step-by-Step Explanation:

The equation should be in the form of y=mx+b

So you already know it's not A. Also you already know it's not D because the line goes at an angle, if "m"(slope) was 0 then the line would be straight horizontal or straight vertical. So that leaves B and C. And finally you know it's not B because the line is going in the positive direction not negative, so the slope has to be positive, also "b" in the equation is the y-intercept, and that's where the line intersects with the y-axis, and you can see that the line intersects at 8 on the graph. Therefore, the answer is C, y=2x+8

Hope this helps!! :)

ms. jeffers is splitting $775 among her three sons. of the oldest gets twice as much as the youngest and the middle son gets $35
Angelina_Jolie [31]

The oldest son will get $370, the middle will get $220 and the youngest will get $185.

Step-by-step explanation:

Given,

Total amount to be split = $775

Let,

Oldest son's share = x

Middle son's share = y

Youngest son's share = z

According to given statement;

x+y+z=775     Eqn 1

the oldest gets twice as much as the youngest

x = 2z             Eqn 2

the middle son gets $35 more than the youngest

y = z+35         Eqn 3

Putting value of x and y from Eqn 2 and 3 in Eqn 1

2z+(z+35)+z=775\\2z+z+35+z=775\\4z=775-35\\4z=740\\

Dividing both sides by 4

\frac{4z}{4}=\frac{740}{4}\\z=185

Putting z=185 in Eqn 2

x=2(185)\\x=370

Putting z=185 in Eqn 3

y=185+35\\y=220

The oldest son will get $370, the middle will get $220 and the youngest will get $185.
