The depth of the water at the end of a pier changes periodically along with the movement of tides. On a particular day, low tide

s occur at 12:00 am and 12:30 pm, with a depth of 2. 5 m, while high tides occur at 6:15 am and 6:45 pm, with a depth of 5. 5 m. Let t = 0 be 12:00 am. Which periodic function, sine or cosine, would be a simpler model for the situation? Explain.

Answer:

A cosine function would be a simpler model for the situation.

The minimum depth (low tide) occurs at

t = 0. A reflection of the cosine curve also has a minimum at t = 0.

A sine model would require a phase shift, while a cosine model does not.

What is the quadratic regression equation?
aniked [119]

Answer:

y=-0.078x^2+8.407x+-92.892

Step-by-step explanation:

but your x and y in desmo than go under the table do y1=ax^2 then under the 2 put a 1 than +bx1+c than you round your a b and c to the nearest thousandth than after that add a b and c then after you get your answer than but x^2 behind a than x behind b then nothing behind c hope this works for you

For what values of x is the following expression a real​ number?<br> <img src="https://tex.z-dn.net/?f=%5Csqrt%7Bx%7D%20-4" id="
IrinaVladis [17]

The square root is defined only for non-negative numbers. In other words, you can compute \sqrt{x} if and only if x \geq 0

If x \geq 0, the square root is a real number, and so is \sqrt{x}-4

(x+3)²(65)=x(6)<br>Solve using quadric formula​
Angelina_Jolie [31]

Step 1: Simplify both sides of the equation.

  • 65x²+390x+585=6x

Step 2: Subtract 6x from both sides.

  • 65x²+390x+585−6x=6x−6x
  • 65x²+384x+585=0

For this equation: a=65, b=384, c=585

  • 65x²+384x+585=0

Step 3: Use quadratic formula with a=65, b=384, c=585

  • x=−b±√b2−4ac/2a
  • x=−(384)±√(384)2−4(65)(585)/
  • 2(65)
  • x=−384±√−4644/130

Therefore, There are no real solutions.
