Using the vertex, it is found that the maximum height of the punt is of 27.7 feet.

The height of the punt, <u>after x seconds</u>, is given by:

f(x) = -0.0152x^2 + 1.25x + 2

It is a quadratic equation with coefficients a = -0.0152, b = 1.25, c = 2.

The maximum value is the value of the function at the vertex, hence:

f_V = -\frac{\Delta}{4a} = -\frac{b^2 - 4ac}{4a}

Applying the coefficients:

f_V = -\frac{b^2 - 4ac}{4a} = -\frac{(1.25)^2 - 4(-0.0152)(2)}{4(-0.0152)} = 27.7

The maximum height of the punt is of 27.7 feet.

2x + 9 = 5x

5x = 2x + 9

Subtract sides 2x

- 2x + 5x = - 2x  + 2x + 9

3x = 9

Divide sides by 3

\frac{3x}{3}  =  \frac{9}{3}  \\

x = 3

CHECK :

2x + 9 = 5x

2(3) + 9 = 5(3)

6 + 9 = 15

15 = 15

So the value is correct.

What is the domain and range of <br> f(x)=2x^2+6x+2
lbvjy [14]

As is the case for any polynomial, the domain of this one is (-infinity,  +infinity).

To find the range, we need to determine the minimum value that f(x) can have.  The coefficients here are a=2, b=6 and c = 2,

The x-coordinate of the vertex is  x = -b/(2a), which here is x = -6/4 = -3/2.

Evaluate the function at x = 3/2 to find the y-coordinate of the vertex, which is also the smallest value the function can take on.  That happens to be y = -5/2, so the range is [-5/2, infinity).

Find the area of a triangle with the given description. (Round your answer to one decimal place.)
Allushta [10]

9514 1404 393

Answer:

  67.0 square units

Step-by-step explanation:

The formula for the area is ...

  Area = 1/2ab·sin(C)

  Area = (1/2)(14)(28)sin(20°) ≈ 67.036 . . . . square units

The area of the triangle is about 67.0 square units.
