VikaD [51]

Answer:

0.76 rounded don't mind my explanation

Step-by-step explanation:

in Geometry if you want a farewell you need to know the parallel lines they never touch they're always the same distance apart it's as if they don't like each other much and there's only one thing that comes between the line that passes right through each of them called the transversal line it has several angle properties just like these: vertically opposite angles are equal corresponding angles are equal alternate interior angles are equal co-interior angles equal 180* vertically opposite angles are equal corresponding angles are equal alternate interior angles are equal co-interior angles equal 180*

How do you make an exponential equation with these two points: (1,2) and (0.5,4)
Over [174]

The required  equation is y=8×(( \frac{1}{2} )^{x}

Step-by-step explanation:

Given,

The two points are (1,2) and (0.5,4)

To find the exponential equation of these given points.

Formula

The general form of exponential equation is y = ab^{x} where, A and B are any real number.

\frac{x^{m} }{x^{n} } = x^{m-n}

Now, the points satisfy the equation.

So,

2 = ab^{1} ------- (1) and

4 =  ab^{0.5} ------ (2)

Now (1) ÷ (2) we get,

\frac{ab }{ab^{0.5} } = \frac{2}{4}

or, b^{0.5} = \frac{1}{2}

or, b = \frac{1}{4} [ by squaring we get]

Now, from (1) we get,

2 = a×\frac{1}{4}

or, a = 8

Hence,

The equation is y=8×(( \frac{1}{2} )^{x}
