The positive solution to the equation [tex]-x^{2} +2x+1=0[/tex] is [tex]x=1+\sqrt{2}[/tex].

Given quadratic equation is:

[tex]-x^{2} +2x+1=0[/tex]

The general form of a quadratic equation is [tex]ax^{2} +bx+c=0[/tex] and [tex]a\neq 0[/tex].

On comparing with general form of quadratic equation

a = -1

b = 2

c = 1

So, from the Shreedharacharya formula,

[tex]x = \frac{-b+-\sqrt{b^{2} -4ac} }{2a}[/tex]

[tex]x = \frac{-2+-\sqrt{2^{2} -4(-1)(1)} }{2*(-1)}[/tex]

[tex]x = 1-\sqrt{2} \\x=1+\sqrt{2}[/tex]

as [tex]x = 1-\sqrt{2}[/tex] is negative

So, the positive solution is [tex]x=1+\sqrt{2}[/tex]

Therefore, the positive solution to the equation [tex]-x^{2} +2x+1=0[/tex] is [tex]x=1+\sqrt{2}[/tex].

Answer:

The percent is 4.9471%

Step-by-step explanation:

Here, we want to find the percentage of observations that lie above z = 1.65

Firstly we find the probability of x < z = 1.65

Hence P ( x > 1.65)

This is obtainable from the standard normal distribution table

The value of P(x > 1.65) = 0.049471

This represents a percentage of 4.9471%

Answer:

4.95/4.9471 is correct

Thank you ☺️☺️

from the first equality we have

3x - 6y = 2

3x = 2 + 6y

x = 2/3 + 2y

we replace x by this value in the second equality

4 * (2/3 + 2y) + 3y = -1

8/3 + 2y + 3y = - 1

5y = - 3/3 - 8/3

5y = - 11/3

y = -11/15

and we can get x now :

and x = 2/3 + 2*(-11/15)

x = 2/3 - 22/15

x = 10/15 - 22/15

x = - 12/15

check

3 * (-12/15) - 6 * (-11/15) = -36/15 + 66/15 = 2

Answer: 66.5 inches

Step-by-step explanation:

Answer:

[tex]4y = 16-2x\\y = \frac{16}{4} - \frac{2x}{4}\\ y = \frac{-1x}{2}+4\\y = 0.5x+4[/tex]

Given parameters:

  Equation of the straight line;

                    2x + 4y = 16

The slope intercept form of the equation is y = mx + c

Where m is the slope of the line

            y and x are the coordinates

             c is the intercept

So, the problem is to write the given equation in form of y = mx + c;

         2x + 4y = 16

                 4y = 16 - 2x

  Divide through by 2;

                 [tex]\frac{4y}{2}[/tex]   = [tex]\frac{16}{2}[/tex] - [tex]\frac{2x}{2}[/tex]

                  2y = 8 - x

                    2y = -x + 8

 Then divide by 2 all through;

                    [tex]\frac{2y}{2}[/tex] = [tex]\frac{-x}{2} + \frac{8}{2}[/tex]

                   y = [tex]\frac{-x}{2} + 4[/tex]

The equation of the line is y = [tex]\frac{-x}{2} + 4[/tex]

Answer:

Add a radical term to both sides and square both sides twice.

Step-by-step explanation:

Given the radical equation

√(b+6) - √b = 5

We are to evaluate the expression for the value of b

Step 1: Add the radical term √b to both sides

√(b+6) - √b +√b = 5+√b

√(b+6) = 5+√b.

Step 2: Square both sides of the equation

(√(b+6))² = (5+√b.)²

b+6 = 25+10√b+ (√b)²

b+6 = 25+10√b + b

Step 3: collect like terms

b+6-b-25 = 10√b

-19 = 10√b

Step 4: square both sides of the resulting equation

(-19)² = (10√b)²

361 = 100b

b = 361/100

b = 3.61

Based on the calculation above, the correct option is C.

Add a radical term to both sides and square both sides twice.

The expression which is equal to the given complex fraction will be

(2-(1/y)/3+(1/y)=(2y-1)/(3y+1)

The complex fraction will be defined as the expression containing the fractions in their numerator and denominator or at least one of them like either numerator or denominator containing fraction in it.

now we have to find the solution to the given expression:

[tex]=\dfrac{2-\frac{1}{y} }{3+\frac{1}{y} }[/tex]

[tex]=\dfrac{\dfrac{2y-1}{y} }{\dfrac{3y+1}{y} }[/tex]

Hey there!

Problem A.
((-10)^3 * 6)^3

= ((-10)(-10)(-10) * 6)^3

= (100(-10) * 6)^3

= (-1,000 * 6)^3

= (-6,000)^3

= (-6,000)(-6,000)(-6,000)

= 36,000,000(-6,000)

= 216,000,000,000

Thus, your answer is: 216,000,000,000

Problem B.
(3^2/5)^3

= (3 * 3 / 5)^3

= (9/5)^3

= 9/5(9/5)(9/5)

= 9 * 9 * 9 / 5 * 5 * 5

= 81 * 9 / 25 * 5

= 729 / 125

≈ =5 104 / 125

≈ 5.832

Thus, your answer is:

5.832 , 5 104/125, or 729 / 125

EITHER OF THOSE SHOULD BE CORRECT BECAUSE THEY ARE EQUIVALENT TO EACH EACH OTHER!

The given asymptote, intercepts and holes of the given function depends

on the numerator and denominator of the function from which we have;

The given function is presented as follows;

[tex]f(x) = \mathbf{ \dfrac{3 \cdot (x - 3) \cdot (x + 2) \cdot (x - 4)}{8 \cdot (x + 9) \cdot (x - 3)}}[/tex]

Given that there is a common factor of (x - 3) in the numerator and the denominator,  we have;

[tex]f(x) = \mathbf{\dfrac{3 \cdot (x + 2) \cdot (x - 4)}{8 \cdot (x + 9)}}[/tex]

The asymptote is obtained by equating the denominator to zero as follows;

8·(x + 9) = 0

x = -9

The intercepts is given by the points the x or y-value are zero, which gives;

[tex]At \ an \ intercept, \ f(x) = \dfrac{3 \cdot (x - 3) \cdot (x + 2) \cdot (x - 4)}{8 \cdot (x + 9) \cdot (x - 3)}= 0[/tex]

3·(x - 3)·(x + 2)·(x - 4) = 0

Therefore;

[tex]At \ the \ \mathbf{y-intercept}, \ f(0) = \dfrac{3 \cdot (0- 3) \cdot (0 + 2) \cdot (0 - 4)}{8 \cdot (0 + 9) \cdot (0 - 3)}= -\dfrac{1}{3}[/tex]

The hole is given by the point where the function is zero.

Placing (x - 3) = 0 in the denominator
