All points on this line are equidistant from the two arms of the parabola, and the line passes through the vertex of the parabola.
What is quadratic equation?
A quadratic equation is a second-degree polynomial equation in a single variable, where the variable is typically denoted by x.
According to question:
A quadratic equation's vertex form is provided by:
y = a(x - h)² + k
where an is a constant that governs the parabola's shape and (h, k) is the parabola's vertex.
In this case, the vertex form of the quadratic equation with a = 3, h = -4, and k = 1 is:
y = 3(x + 4)² + 1
To find the equation of the axis of symmetry, we need to determine the x-coordinate of the vertex, which is given by -h. In this case, -h = -(-4) = 4.
The line that represents the axis of symmetry has the following equation, then:
x = 4
This is because all points on this line are equidistant from the two arms of the parabola, and the line passes through the vertex of the parabola.

Find the range, variance, and standard deviation for the sample data. What do the results tell us about the
population of all celebrities? Based on the nature of the amounts, what can be inferred about their precision?
What do the results tell us about the population of all the celebrities?
To find the range, variance, and standard deviation for this sample data, we can use the following formulas:
Range = maximum value - minimum value
Variance = sum of (each value minus the mean) squared, divided by the sample size
Standard deviation = the square root of the variance
Using these formulas, we can calculate the following:
[tex]Range = 5500 - 950 = 4550[/tex]
[tex]Mean = (5500 + 3700 + 3200 + 1200 + 1000 + 950) / 6 = 2466.67[/tex]
[tex]Variance = [(5500 - 2466.67)^2 + (3700 - 2466.67)^2 + (3200 - 2466.67)^2 + (1200 - 2466.67)^2 + (1000 - 2466.67)^2 + (950 - 2466.67)^2] / 5 = 3031191.11[/tex]
[tex]Standard deviation = sqrt(3031191.11) = 1742.41[/tex]
The range of this data set is quite large, ranging from $950 million to $5.5 billion. The variance and standard deviation are also quite large, indicating that there is a wide range of net worths among celebrities. These results suggest that the population of all celebrities likely has a large variation in net worth, with some celebrities being extremely wealthy and others having much lower net worths.
Given the nature of these amounts, it is likely that they are precise to the nearest million dollars. It is possible that the true net worths of these celebrities are slightly higher or lower than the reported values, but the reported values are likely accurate to within a few million dollars.

A Ferris wheel is 21 meters in diameter and completes 1 full revolution in 12 minutes.
A Ferris wheel is 21 meters in diameter and boarded from a platform that is 1 meter above the ground.
The six o'clock position on the Ferris wheel is level with the loading platform. The wheel completes 1
full revolution in 12 minutes. The function h (t) gives a person's height in meters above the ground t
minutes after the wheel begins to turn.
Part A: I need to find the amplitude, midline, and period of h(t).
Part B: Assume the person had just boarded the Ferris wheel from the platform and that the Ferris wheel starts spinning at time t=0. Find a formula for the height function h(t).
Part C: If the Ferris wheel continues to turn, how high off the ground is a person after 33 minutes?
The person is approximately 10.68 meters above the ground after 33 minutes.
Part A:
The amplitude of h(t) is half the vertical distance between the highest and lowest points on the Ferris wheel. The highest point occurs when the person is at the top of the wheel, which is 21/2 = 10.5 meters above the midline. The lowest point occurs when the person is at the bottom of the wheel, which is 1 meter above the midline. Therefore, the amplitude is [tex]10.5 - 1 = 9.5[/tex] meters.
The midline of h(t) is the average of the highest and lowest points, which is [tex](10.5 + 1)/2 = 5.75[/tex] meters.
The period of h(t) is the time it takes for one complete revolution of the Ferris wheel, which is 12 minutes.
Part B:
The height function h(t) can be modeled by a sinusoidal function of the form:
h(t) = A sin(B(t - C)) + D
where A is the amplitude, B is the frequency (in radians per minute), C is the phase shift (in minutes), and D is the midline.
Using the values from Part A, we have:
A = 9.5
D = 5.75
The frequency can be found by dividing 2π by the period:
[tex]B = 2\pi /12 = \pi /6[/tex]
The phase shift is the time it takes for the Ferris wheel to complete one-quarter of a revolution from the starting position (at t=0), which is 3 minutes. Therefore, C = 3.
Putting it all together, the formula for the height function is:
[tex]h(t) = 9.5 sin(\pi /6 (t - 3)) + 5.75[/tex]
Part C:
To find the height of a person after 33 minutes, we simply substitute t = 33 into the height function:
h(33) = 9.5 sin(π/6 (33 - 3)) + 5.75
≈ 10.68 meters
Therefore, the person is approximately 10.68 meters above the ground after 33 minutes.

y = x^2 + 2x - 2
y = x + 10
Answer:
x1 = -4,
y1 = 6,
x2 = 3,
y2 = 13
Step-by-step explanation:
{y = x^2 + 2x - 2,
{y = x + 10;
Since both equations are equal to y, they are equal to one another aswell:
[tex] {x}^{2} + 2x - 2 = x + 10[/tex]
Collect like-terms:
[tex] {x}^{2} + x - 12 = 0[/tex]
a = 1, b = 1, c = -12
Let's solve this quadratic equation:
[tex]d = {b}^{2} - 4ac = {1}^{2} - 4 \times 1 \times ( - 12) = 1 + 48 = 49 > 0[/tex]
[tex]x1 = \frac{ - b - \sqrt{d} }{2a} = \frac{ - 1 - 7}{2 \times 1} = \frac{ - 8}{2} = - 4[/tex]
[tex]x2 = \frac{ - b + \sqrt{d} }{2a} = \frac{ - 1 + 7}{2 \times 1} = \frac{6}{2} = 3[/tex]
{x1 = -4,
{y1 = -4 + 10 = 6;
{x2 = 3,
{y2 = 3 + 10 = 13
Answer:
(- 4, 6 ) , (3, 13 )
Step-by-step explanation:
y = x² + 2x - 2 → (1)
y = x + 10 → (2)
substitute y = x² + 2x - 2 into (2)
x² + 2x - 2 = x + 10 ← subtract x + 10 from both sides
x² + x - 12 = 0 ← in standard form
(x + 4)(x - 3) = 0 ← in factored form
equate each factor to zero and solve for x
x + 4 = 0 ⇒ x = - 4
x - 3 = 0 ⇒ x = 3
substitute these values into (2) for corresponding values of y
x = - 4 : y = - 4 + 10 = 6 ⇒ (- 4, 6 )
x = 3 : y = 3 + 10 = 13 ⇒ (3, 13 )

Is (-5, -5) a solution to this system of equations? y = -2x - 15 y = 2x + 5 yes or no
No, (-5, -5) is not a solution to this system of equations.
To determine whether (-5, -5) is a solution to the system of equations y = -2x - 15 and y = 2x + 5, we can substitute the values of x and y into each equation and see if both equations are true.
Substituting x=-5 and y=-5 into the first equation, we get:
y = -2x - 15
-5 = -2(-5) - 15
-5 = 5 - 15
-5 = -10
This is not true, so (-5, -5) is not a solution to the first equation.
Substituting x=-5 and y=-5 into the second equation, we get:
y = 2x + 5
-5 = 2(-5) + 5
-5 = -5
This is true, so (-5, -5) is a solution to the second equation.
Since (-5, -5) does not satisfy both equations simultaneously, it is not a solution to the system of equations y = -2x - 15 and y = 2x + 5.

What is a circle ?
A circle is a two-dimensional geometric shape that consists of all the points in a plane that are at a fixed distance from a given point, called the center.
In the given diagram, we have a circle O with chords AB, CD, AD, and BC. The chords AD and BC intersect at point E.
Based on the diagram, we can see that the opposite angles in the quadrilateral AEDC are supplementary (i.e., they add up to 180 degrees). Therefore, we have:
[tex]\angle A + \angle C = 180^\circ[/tex]
Similarly, the opposite angles in the quadrilateral BEFC are supplementary. Thus,
[tex]\angle B + \angle C = 180^\circ[/tex]
We can rewrite the second equation as:
[tex]\angle C = 180^\circ - \angle B[/tex]
Substituting this value of \angle C into the first equation, we get:
[tex]\angle A + 180^\circ - \angle B = 180^\circ[/tex]

If all the triangles are equilateral, what is the surface area of the pyramid, in square inches?
The surface area of the triangular pyramid is approximately 256.224 square inches.
How do we calculate the surface area?The surface area of a triangular pyramid can be calculated by summing the areas of its four triangular faces.
Given that one of the triangular faces has a length of 12 inches and a height of 10.39 inches, we can calculate its area using the formula for the area of an equilateral triangle:
Area = (1/2) * base * height
For the given triangular face:
Base = 12 inches
Height = 10.39 inches
Plugging in these values, we get:
Area of one triangular face:
= (1/2) * 12 * 10.39
= 64.056 square inches
Since there are four triangular faces in a triangular pyramid, the total surface area of the pyramid is:

Which graph represents a reflection of f(x) = 1/3(9)^x across the x-axis?
Answer:
The reflection of $f(x)=1/3(9)^x$ across the x-axis is equivalent to multiplying the entire function by -1 because reflecting across the x-axis changes the sign of y-coordinates. Therefore, the graph of $g(x)=-1/3(9)^x$ represents the reflection of $f(x)$ across the x-axis.

The degree of one polynomial is m. The degree of a second polynomial is n. the two polynomials are multiplied together. what is the degree of the resulting polynomial? Explain.
Therefore, the degree of the resulting polynomial is m + n when two polynomials of degree m and n are multiplied together.
What is polynomial?A polynomial is a mathematical expression consisting of variables and coefficients, which involves only the operations of addition, subtraction, multiplication, and non-negative integer exponents. Polynomials can have one or more variables and can be of different degrees, which is the highest power of the variable in the polynomial.
Here,
When two polynomials are multiplied, the degree of the resulting polynomial is the sum of the degrees of the original polynomials. In other words, if the degree of the first polynomial is m and the degree of the second polynomial is n, then the degree of their product is m + n.
This can be understood by looking at the product of two terms in each polynomial. Each term in the first polynomial will multiply each term in the second polynomial, so the degree of the resulting term will be the sum of the degrees of the two terms. Since each term in each polynomial has a degree equal to the degree of the polynomial itself, the degree of the resulting term will be the sum of the degrees of the two polynomials, which is m + n.

The Bureau of Labor Statistics generally uses 90% confidence levels in its reports. One
report gives a 90% confidence interval for the mean hourly earnings of American workers in
2000 as $15.49 to $16.11. If the null hypothesis states that the mean hourly earnings of all
workers in 2000 was $16.15, would this hypothesis be rejected in a two-tailed test if a = .10?
What about a null hypothesis stating that the mean was $15.50? Explain your reasoning.
For a two-tailed test with a 90% confidence interval and a significance level of 0.10, the null hypothesis of $16.15 would be rejected, but the null hypothesis of $15.50 would not be rejected.
How to check if null hypothesis will be rejected?Identify the given information, including confidence level, confidence interval, null hypothesis, and significance level (alpha).Check if the null hypothesis values fall within the confidence interval.If the null hypothesis values fall within the confidence interval, we do not have enough evidence to reject the null hypotheses at the given significance level.If the null hypothesis values fall outside the confidence interval, we have enough evidence to reject the null hypotheses at the given significance level.Consider the significance level (alpha) to determine the level of significance for rejecting the null hypotheses.Conclude whether the null hypotheses should be rejected or not at the given significance level.Given:
Confidence level: 90%
Confidence interval for American employees' mean hourly wages in 2000: $15.49 to $16.11
Null hypothesis 1: Mean hourly earnings of all workers in 2000 was $16.15
Null hypothesis 2: Mean hourly earnings of all workers in 2000 was $15.50
Significance level (alpha): 0.10
For a two-tailed test with a 90% confidence interval and a significance level (alpha) of 0.10:
Null hypothesis 1:
In this case, since the null hypothesis value of $16.15 falls outside the confidence interval of $15.49 to $16.11, we would have enough evidence to reject the null hypothesis at the given significance level of 0.10. This means that we can reject the null hypothesis and conclude that the mean hourly earnings of all workers in 2000 is significantly different from $16.15.
Null Hypothesis 2:
In this case, since the null hypothesis value of $15.50 falls within the confidence interval of $15.49 to $16.11, we do not have enough evidence to reject the null hypothesis at the given significance level of 0.10. This means that we would not reject the null hypothesis and cannot conclude that the mean hourly earnings of all workers in 2000 is significantly different from $15.50.
Thus, the null hypothesis stating that the mean hourly earnings of all workers in 2000 is $16.15 would be rejected, while the null hypothesis stating that the mean hourly earnings of all workers in 2000 is $15.50 would not be rejected, based on a two-tailed test with a 90% confidence interval and a significance level of 0.10.
