3) Expresa mediante una fórmula la función que a un número entero x le hace corresponder el doble del número siguiente a x. Haz

jonny [76]

Answer: The function is: f(x) = 2*(x +1)

Step-by-step explanation:

This can be translated to:

"write an equation of a function where a whole number x corresponds to the next number to x"

the next whole number to x is x+1., and we want the double of that.

Then we have that our function is:

f(x) = 2*(x +1)

Now we can do a little table of it:

f(0) = 2*(0 + 1) = 2

f(1) = 2*(1 + 1) = 4

f(2) = 2*(2+ 1) = 6

What are the roots of x in -10x2 + 12x − 9 = 0?

hoa [83]

Answer:

$x_1=\frac{3(2+i\sqrt{6})}{10}$

$x_2=\frac{3(2-i\sqrt{6})}{10}$

Step-by-step explanation:

Use the Quadratic formula:

$x=\frac{-b\±\sqrt{b^2-4ac}}{2a}$

You can identify that, in this case:

$a=-10\\b=12\\c=-9$

Now you need to substitute these values into the formula:

$x=\frac{-12\±\sqrt{12^2-4(-10)(-9)}}{2(-10)}$

$x=\frac{-12\±\sqrt{-216}}{-20}$

Remember that:

$i=\sqrt{-1}$

Therefore,rewriting and simplifying, you get:

$x=\frac{-12\±6i\sqrt{6}}{-20}$

$x=\frac{-6(2\±i\sqrt{6})}{-2(10)}$

$x=\frac{3(2\±i\sqrt{6})}{10}$

Then, you get the following roots:

$x_1=\frac{3(2+i\sqrt{6})}{10}$

$x_2=\frac{3(2-i\sqrt{6})}{10}$
