Tiffany kicks a soccer ball off the ground and in the air, with an initial velocity of 28 feet per second. Using the formula H(t
Sedaia [141]

Answer:

The maximum height of soccer ball  is 12.25 ft.

Step-by-step explanation:

It is given that Tiffany kicks a soccer ball off the ground and in the air, with an initial velocity of 28 feet per second. It means v = 28 ft.

Given formula is

H(t)=-16t^2+vt+s

The initial height of ball is 0.

H(0)=-16(0)^2+v(0)+s

0=s

The height of ball defined by the function

H(t)=-16t^2+(28)t+0

H(t)=-16t^2+28t

It is a downward parabola and the vertex of a downward parabola is the point of maxima.

The vertex of a parabola f(x)=ax^2+bx+c is

(\frac{-b}{2a},f(\frac{-b}{2a}))

\frac{-b}{2a}=\frac{-28}{2(-16)}=0.875

H(0.875)=-16(0.875)^2+28(0.875)=12.25

Therefore the maximum height of soccer ball  is 12.25 ft.

What is meant by green mathematics?
ad-work [718]

The green mathematics tells about the impulse response of an in homogeneous linear differential operator.

According to the statement

we have to explain the green mathematics.

In mathematics, Actually there is a Green Function which was founded by a mathematician George Green.

In this function, a Green's function is the impulse response of an in homogeneous linear differential operator defined on a domain with specified initial conditions or boundary conditions.

The example of green function is the Green's function G is the solution of the equation LG = δ, where δ is Dirac's delta function; the solution of the initial-value problem Ly = f is the convolution (G ⁎ f), where G is the Green's function.

Actually in this function, it gives the relationship between the line integral of two dimensional vector over a closed path by a integral.

In this there is a green theorem, which  relates a line integral around a simply closed plane curve C and a double integral over the region enclosed by C.

So, The green mathematics tells about the impulse response of an in homogeneous linear differential operator.
