Use the equation y=3(1/2)^x to determine the value of y if x = -2

sergey [27]

Given :-

A Equation , $\sf y = 3(1/2)^x$

To find :-

The value of y at x = -2.

Solution :-

The given equation is ,

$\red{\longrightarrow}\sf y = 3(1/2)^x$

Now on substituting x = -2 , we have,

$\red{\longrightarrow} y = 3(1/2)^{-2}$

Using the property of exponents as ,

$\red{\longrightarrow} \sf a^{-m}= 1/a^m$

We have ,

$\red{\longrightarrow}\sf y = 3(2)^2$

$\red{\longrightarrow}\sf y = 3(4)$

$\red{\longrightarrow}\bf y = 12$

Hence the required answer is 12.

Answer:

$x= \frac{3-3\sqrt{7}i }{4}$ and $x= \frac{3+3\sqrt{7}i }{4}$

Step-by-step explanation:

We have to solve the given equation - 2x² + 3x - 9 = 0

To solve the equation given above we have to factorize the left-hand side of the equation.

But it can not be factorized. So, use the Sridhar Achaya formula.

Therefore, $x= \frac{-3 + \sqrt{3^{2}-4 \times (-2) \times (-9) } }{2\times (-2)}$ and $x= \frac{-3 -\sqrt{3^{2}-4 \times (-2) \times (-9) } }{2\times (-2)}$

So, $x= \frac{3-3\sqrt{7}i }{4}$ and $x= \frac{3+3\sqrt{7}i }{4}$ {Where $i=\sqrt{-1}$ }

Therefore, the solutions are imaginary numbers. (Answer)

Note: The Sridhar Acharya Formula gives if ax² + bx + c = 0, then the roots of the equation are $x = \frac{-b + \sqrt{b^{2}-4ac } }{2a}$ and $x = \frac{-b - \sqrt{b^{2}-4ac } }{2a}$ .
