If both diagonals of a quadrilateral bisect each other when is the quadrilateral a parallelogram?

1 answer:

6 0

It is more than just a quadrilateral. In fact it is going to be hard to pick.

These facts suit a square, a rectangle, a rhombus, and a parallelogram. And the above statement is true, but maybe a little harder to prove than the converse of the statement, which is the usual one you find.

The converse is "If you have a parallelagram, the diagonals bisect each other."

You might think a trapezoid deserves some mention. The diagonals of a trapezoid do not bisect each other.

How the transformations of the functions f(x)=15tanx and g(x)=tanx+15 differ?

Irina-Kira [14]

The transformation of f(x)=15tanx would be achieved by dilating y=tanx graph 15 times. This transformation will cause y'=15 y. This will increase the value of dilation become 15 times of the original

The transformation of g(x)=15tanx would be achieved by shifting y=tanx graph 15 right. This transformation will cause x'=x+15. This will change the value from tan x into tan(x+15)

If abx - 5 = 0, what is x in terms of a and b?

Harlamova29_29 [7]

Here we want to have x on one side of equation so,
we put number 5 on right side of equation:
abx=5
then we divide both sides by ab to obtain x on left side:
Result:
x= $\frac{5}{ab}$
