Write two division equations for 16 times 7/8 = 14

1 answer:

6 0

Two division equations for 16 times 7/8=14 are:
14/(7/8)=16
14/16= 7/8
The reason that these equations work is because the inverse operation of multiplication is division. Any factors of the the multiplication equation can divide the product by the factor and the answer would be the other factor. Example:
AB=C
C/B= A
C/A=B
The product always has to be the first Number of the equation while either factor follows.

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's...factorise: 25x²-y²?

Bogdan [553]

Factorising an equation is putting it into bracket form.
This has square numbers and so needs double brackets

(5x - y) (5x+y)
If you then check this by multiplying the brackets out again you will get:
5x^2 - 5xy + 5xy - y^2

The positive and negative 5xy's cancel each other out and you are left with its original form. Your answer is
(<span>5x - y) (5x+y)</span>

Simplify.

Ray Of Light [21]

$Use\ \sqrt{ab}=\sqrt{a}\cdot\sqrt{b}\\\\\sqrt{75}=\sqrt{25\cdot3}=\sqrt{25}\cdot\sqrt3=5\sqrt3\to\boxed{B)}$
