Answer:

The  value comes out to be  

x=\frac{1}{2}+\frac{\sqrt{17}}{2}

Step-by-step explanation:

The quadratic equation is an equation containing a single variable of degree 2. Its general form is ax^{2} +bx + c=0.

The discriminant is the part of the quadratic formula underneath the square root symbol: b²- 4ac. The discriminant tells us whether there are two solutions, one solution, or no solutions.

The equation we are given is :x+4=x^{2} \\x^{2} -x-4=0\\

We know the formula as :

x=[-b±\sqrt{b^{2}-4ac}] ×\frac{1}{2a}

x=[-(-1)±\sqrt{(-1)^{2} -4(1)(-4)}]×\frac{1}{2(1)}

x=\frac{1}{2} ±\frac{\sqrt{17} }{2} }

Since x≥0

Other negative option is neglected

x=\frac{1}{2}+\frac{\sqrt{17}}{2}

In a list of numbers, the pattern increases by 0.001 as you move to the right. If the third number in the list is 0.064, what is
avanturin [10]

The <em>correct answer</em> is:


The first number is 0.062.


Explanation:


Let x represent the first number in the list.


We add 0.001 to each number to find the next number; this gives us:

x + 0.001 + 0.001 = 0.064


Combining like terms, we have:

x + 0.002 = 0.064


Subtract 0.002 from each side:

x + 0.002 - 0.002 = 0.064 - 0.002

x = 0.062
