Flying fish use their pectoral fins like airplane wings to glide through the air. Suppose a flying fish reaches a maximum height

of 5 ft after flying a horizontal distance of 33 ft. Write a quadratic function y=a(x-h)^2+k that models the flight path assuming the fish leaves the water at (0,0). Describe how the changing value of a,h, or k affects the flight path

The flight is in the shape of a parabola with a vertex 5 feet above the water and  1/2 * 33 = 16.5 feet horizontally from the point of leaving the water

y = a(x - h)^2 + k

where  (h,k)  is the vertex of the  parabola and here it is (5 , 16.5), so we have the function:-

y = a(x - 16.5)^2 + 5

when x = 0 y = 0  so

0 = a(-16.5)^2 + 5

which gives a = -0.018365

So our function for the flight path is

y = -0.018365(x - 16.5)^2 + 5     Answer

Answer:

Equation: y= -0.00459*(x-33)^{2} + 5

Step-by-step explanation:

Using the value as height in axis y, and horizontal distance in axis x

y=a*(x-h)^{2}+k\\  h=33\\k=5\\y=a*(x-33)^{2}+5

X=0, Y=0

y=a*(x-33)^{2}+5\\ 0=a*(0-33)^{2}+5\\a=-\frac{5}{33^{2} } =-0.00459

In the figure can see the motion of the fish while flying like airplane

Answer:

C) 56

Step-by-step explanation:

These angles are supplementary (they add up to 180):

3x + 31 + 2x - 6 = 180

5x + 25 = 180

5x = 180 - 25

5x = 155

x = 31

<FEG:

2x - 6

2(31) - 6

62 - 6

7n-(4n-3) combining like terms with negative coefficient and distribution
sladkih [1.3K]

\huge\text{Hey there!}

\huge\textbf{Equation/Question:}

\mathbf{7n - (4n - 3)}

\huge\textbf{Convert equation/question to:}

\mathbf{= 7n - 1(4n - 3)}

\huge\textbf{Solving the equation/question:}

\mathbf{= 7n - 1(4n) - 1(-3)}

\mathbf{= 7n - 4n + 3}

\huge\textbf{Combine the like terms:}

\mathbf{= (7n - 4n) + 3}

\mathbf{= 7n - 4n + 3}

\mathbf{= 3n + 3}

\huge\textbf{Therefore, your answer should be:}

\huge\boxed{\frak{3n + 3}}\huge\checkmark

\huge\text{Good luck on your assignment \& enjoy your day!}
