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]
What is the general form of a quadratic equation?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].

If necessary, round your answer to the nearest tenth.
25%
6.3%
95.5%
4.5%
Answer:
25%
Step-by-step explanation:
so you will add 4,3,5=12
3/12=0.25 then = 25%
The probability that both Michelle and Garth will drive a red bumper car is calculated as; 4.5%
What is the Probability?We are told that;
Number of red cars = 3 red cars
Number of green cars = 4 green cars.
Number of blue cars = 5 blue cars.
Total Number of Cars = 3 + 4 + 5
Total number of Cars = 12 cars
Probability that Michellewill drive a red bumper car is;
P(A) = 3/12
Probability that Garth will drive a red bumper car is;
P(B) = 2/11
Probability that both Michelle and Garth will drive a red bumper car is;

Using the following function, explain how the following features (asymptotes,
intercepts, holes) can be identified/constructed in the graph.
3(2-3)(x+2)(x-4)/8(6+9) (2-3)
The given asymptote, intercepts and holes of the given function depends
on the numerator and denominator of the function from which we have;
The vertical asymptote is the line x = -9The x-intercept occurs at the points, x = -2, and x = 4, the y-intercept is located at the point at which y = [tex]-\dfrac{1}{3}[/tex]The hole is at the point (3, 0)How can the properties of the function be found?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 asymptote is the line x = -9The 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;
x = -2, x = 4 at the x-intercepts[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.

Put the following equation of a line into slope-intercept form, simplifying all
fractions
2x + 4y = 16
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]
Which statement describes a process to solve square root b plus six minus square root b =5 Add a radical term to both sides and square both sides only once. Add a constant term to both sides and square both sides only once. Add a radical term to both sides and square both sides twice. Add a constant term to both sides and square both sides twice.
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.
Answer:
C

In a standard Normal distribution, what percentage of observations lie above z = 1.65?
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:
