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.

Find the center and radius of circle and graph it <br><br> <img src="https://tex.z-dn.net/?f=%28x-4%29%5E%7B2%7D%20%2B%28%20y%20
sergeinik [125]

Answer:

centre = (4,-2)

radius = 3

Step-by-step explanation:

The centre-radius form of the circle equation is in the format

(x – h)² + (y – k)² = r²,

with the centre being at the point (h, k) and the radius being "r"

Given in the question an expression which can be write as

<h3> (x – 4)² + (y – (-2))² = 3²</h3>

So, by translating we can say that

centre = (4,-2)

and

radius = 3

trasher [3.6K]

Answer with explanation:

A regular polygon is simple closed geometrical shape, only made up of line segments.

And Regular Tessellation, is geometrical shape, made up of regular polygons having, 3 ,or 4 or 6 sides.

It is combination of, only single kind of polygon,either, polygon having 3 sides, or ,4 sides or 6 sides.

→Regular polygon having 3 sides is Called Equilateral Triangle.

→Regular polygon having 4 sides is Called Square.

→Regular polygon having 6 sides is Called Regular Hexagon.

⇒Regular polygon having , 8 sides will not form a regular tessellation.

Option D
