The equations of the functions are y = -4(x + 1)^2 + 2, y = 2(x - 2)^2 + 1 and y = -(x - 1)^2 - 2

A quadratic function is represented as:

y = a(x - h)^2 + k

Question #6

The vertex of the graph is

(h, k) = (-1, 2)

So, we have:

y = a(x + 1)^2 + 2

The graph pass through the f(0) = -2

So, we have:

-2 = a(0 + 1)^2 + 2

Evaluate the like terms

a = -4

Substitute a = -4 in y = a(x + 1)^2 + 2

y = -4(x + 1)^2 + 2

Question #7

The vertex of the graph is

(h, k) = (2, 1)

So, we have:

y = a(x - 2)^2 + 1

The graph pass through (1, 3)

So, we have:

3 = a(1 - 2)^2 + 1

Evaluate the like terms

a = 2

Substitute a = 2 in y = a(x - 2)^2 + 1

y = 2(x - 2)^2 + 1

Question #8

The vertex of the graph is

(h, k) = (1, -2)

So, we have:

y = a(x - 1)^2 - 2

The graph pass through (0, -3)

So, we have:

-3 = a(0 - 1)^2 - 2

Evaluate the like terms

a = -1

Substitute a = -1 in y = a(x - 1)^2 - 2

y = -(x - 1)^2 - 2

Hence, the equations of the functions are y = -4(x + 1)^2 + 2, y = 2(x - 2)^2 + 1 and y = -(x - 1)^2 - 2

Answer:

\(-2y^6 + 16x^3 + -\frac{1}{2}x\)

Answer:

\(\frac{4x^2}{y^6}\)

Step-by-step explanation:

using the rules of exponents

\(a^{m}\) × \(a^{n}\) = \(a^{m+n}\)

\(\frac{1}{a^{-m} }\) ⇔ \(a^{m}\)

\(a^{0}\) = 1

\(\frac{2x^{2}.8x^{-2} }{4x^{-2}.y^{6} }\)

= \(\frac{16x^{2-2} }{4x^{-2}.y^{6} }\)

= \(\frac{16x^{0} }{4x^{-2}.y^{6} }\)

= \(\frac{16}{4x^{-2}.y^{6} }\)

= \(\frac{4x^2}{y^{6} }\) ( in positive exponent form )

A good sampling method for this scenario would be a probability-based method called Simple Random Sampling.

In Simple Random Sampling, each individual from the population of individuals who have high cholesterol has an equal chance of being selected for the sample. This ensures that the sample is representative of the population and that each individual in the population has a known non-zero probability of being selected.

This method can be supported by the fact that it is easy to implement, and it does not require any prior knowledge of the population characteristics. It also ensures that the sample is unbiased and has a good chance of being representative of the population.

Additionally, Simple Random Sampling is also a cost-effective sampling method as it is less expensive and time-consuming than other sampling methods such as stratified random sampling or cluster sampling.

Answer:

-2

Step-by-step explanation:

The coordinate of a point that divides a line AB in a ratio a:b from A(\(x_1,y_1\)) to B(\(x_2,y_2\)) is given by the formula:

\((x,y)=(\frac{bx_1+ax_2}{a+b} ,\frac{by_1+ay_2}{a+b} )=(\frac{a}{a+b}(x_2-x_1)+x_1 ,\frac{a}{a+b}(y_2-y_1)+y_1 )\)

Given that a line JK, with  Point J is at ( -6, - 2) and point K is at point (8, - 9) into a ratio of 2:5. The x coordinate is given as:

\(x=\frac{2}{2+5} (8-(-6))+(-6)=\frac{2}{7}(14) -6=4-6=-2\)

Line segments can be divided into equal or unequal ratios

The x coordinate of the segment is -2

The coordinates of points J and K are given as:

\(J = (-6,-2)\)

\(K = (8,-9)\)

The ratio is given as:

\(m : n =2 : 5\)

The x-coordinate is then calculated using:

\(x = (\frac{m}{m + n }) (x_2 - x_1) + x_1\)

So, we have:

\(x = (\frac{2}{2 + 5 }) (8 - -6) -6\)

\(x = (\frac{2}{7}) (14) -6\)

Expand

\(x = (2) (2) -6\)

Open bracket

\(x = 4 -6\)

Subtract 6 from 4

\(x = -2\)

Hence, the x coordinate of the segment is -2

Answer:

20 weeks

Step-by-step explanation:

Salma's savings can be represented by the equation S = 35 + 8t, where t is the number of weeks after the beginning of the year.

Henry's savings can be represented by the equation H = 95 + 5t

To determine the number of weeks after the beginning of the year until Salma and Henry have the same amount of money saved, we need to set the two equations equal to each other and solve for t:

35 + 8t = 95 + 5t

3t = 60

t = 20

So it would take Salma and Henry 20 weeks after the beginning of the year to have the same amount of money saved.

The three options that are true about the equation of the circle are:

B) The center of the circle lies on the x-axis

A) The radius of the circle is 3 units.

E) The radius of this circle is the same as the radius of the circle whose equation is x² + y² = 9.

The standard equation of a circle is expressed as:

x² + y² + 2gx + 2fy + c = 0

Where:

Center is (-g, -f)

radius = √g²+f²-C

Given a circle whose equation is x² + y² - 2x - 8 = 0

Get the Centre of the circle:

2gx = -2x

2g = -2

g = -1

Similarly, 2fy = 0

f = 0

Centre = (-(-1), 0) = (1, 0)

This shows that the center of the circle lies on the x-axis

r = radius = √g² + f² - C

radius = √1² + 0² - (-8)

radius =√9 = 3 units

The radius of the circle is 3 units.

For the circle x² + y² = 9, the radius is expressed as:

r² = 9

r = 3 units

Hence the radius of this circle is the same as the radius of the circle whose equation is x² + y² = 9.

In mathematics, the volume element is defined as an infinitesimal unit of volume in a larger space.

For spherical polar coordinates, the volume element can be found as follows:

\(\[\large d V =r^{2}\sin\theta dr d\theta d\phi\]\) Here,\(\[\large r= \sqrt{x^{2} +y^{2} +z^{2}}\]\) is the distance of the point from the origin, \(\[\large \theta = \cos^{-1}\frac{z}{r}\]\) is the angle made by the point with the positive z-axis, and \(\[\large \phi = \tan^{-1}\frac{y}{x}\]\) is the angle made by the point with the positive x-axis.

To find the volume element for spherical polar coordinates, we use the following formula:\

\(\large d V =r^{2}\sin\theta dr d\theta d\phi\]\) where r is the distance of the point from the origin, θ is the angle made by the point with the positive z-axis, and ϕ is the angle made by the point with the positive x-axis.

For the given spherical polar coordinates,

\(\[\large x= r\sin\theta \cos\phi,\qquad y= r\sin\theta \sin\phi,\qquad z= r\cos\theta\]\)

To find the value of r, we use the distance formula:\(\[\large r= \sqrt{x^{2} +y^{2} +z^{2}}\]Substituting the values of x, y, and z, we get\[\large r= \sqrt{(r\sin\theta \cos\phi)^{2} +(r\sin\theta \sin\phi)^{2} +(r\cos\theta)^{2}}\]\[\large r= \sqrt{r^{2}(\sin^{2}\theta\cos^{2}\phi +\sin^{2}\theta\sin^{2}\phi +\cos^{2}\theta)}\]\[\large r= \sqrt{r^{2}(\sin^{2}\theta(\cos^{2}\phi +\sin^{2}\phi) +\cos^{2}\theta)}\]\[\large r= \sqrt{r^{2}(\sin^{2}\theta +\cos^{2}\theta)}\]\[\large r= r\]\)

Therefore, the value of r is r.

Substituting the value of r in the volume element formula,

\(\[\large d V =r^{2}\sin\theta dr d\theta d\phi\]\[\large d V =r^{2}\sin\theta dr d\theta d\phi\]\[\large d V =r^{2}\sin\theta (d(r)\ d(\theta)\ d(\phi))\]\)

Now, we have to calculate the values of d(r), d(θ), and d(ϕ).

To find d(r), we differentiate r with respect to r:

\(\[\large \frac{d(r)}{dr} = 1\]\)

Therefore, d(r) = dr.To find d(θ), we differentiate θ with respect to z:

\(\[\large \theta = \cos^{-1}\frac{z}{r}\]\[\large \frac{d(\theta)}{dz} = \frac{1}{\sqrt{r^{2} -z^{2}}}\]\)

Therefore, d(θ) = dz/√(r² - z²).

To find d(ϕ), we differentiate ϕ with respect to x:

\(\[\large \phi = \tan^{-1}\frac{y}{x}\]\[\large \frac{d(\phi)}{dx} = -\frac{y}{x^{2} +y^{2}}\]\)

Therefore, d(ϕ) = -y/(x² + y²)dx.

Substituting the values of d(r), d(θ), and d(ϕ) in the volume element formula,

\(\[\large d V =r^{2}\sin\theta dr d\theta d\phi\]\[\large d V =r^{2}\sin\theta\ (dr)\left(\frac{dz}{\sqrt{r^{2} -z^{2}}}\right)\left(-\frac{y}{x^{2} +y^{2}}dx\right)\]\)

Multiplying all the terms,

\(\[\large d V =-r^{2}\sin\theta\frac{y}{(x^{2} +y^{2})^{1/2}}\frac{dz\ dx\ dr}{(r^{2} -z^{2})^{1/2}}\]\)

Finally, simplifying the equation,

\(\[\large d V =r^{2}\sin\theta\frac{y}{(x^{2} +y^{2} +z^{2})^{3/2}}\ dz\ dx\ dr\]\)

The volume element for spherical polar coordinates is given by\(\[d V =r^{2}\sin\theta dr d\theta d\phi\]\) The value of r is r.Substituting the value of r in the volume element formula, we get\(\[d V =r^{2}\sin\theta\frac{y}{(x^{2} +y^{2} +z^{2})^{3/2}}\ dz\ dx\ dr\]\)

Which of the following is an accurate definition for the power of a statistical test is C. The power of a statistical test refers to the probability of rejecting a false null hypothesis. This means that the test is able to correctly identify when there is a significant difference between two groups or conditions.

statistical tests are used to determine whether the results of an experiment are likely due to chance or whether there is a real effect. The null hypothesis states that there is no significant difference, while the alternative hypothesis states that there is. The power of a statistical test refers to the ability of the test to correctly reject the null hypothesis when it is false, and thus support the alternative hypothesis.

Answer:

When we multiply or divide by a negative to solve an inequality, it's the same as multiplying or dividing by a negative to solve a regular equation! Just remember to multiply or divide both sides by the same quantity, then simplify! Remember, when multiplying or dividing by a negative YOU MUST FLIP THE INEQUALITY SIGN.

Step-by-step explanation:

You are welcome.

And I hope this helps.      :)

Answer:

Step-by-step explanation:

If you begin with an inequality and wish to solve for one of the variables, you must isolate that variable on the right side of a new inequality.  Now supposing that that variable is negative in the given inequality, and that you must change that sign to positive.  Generally you can either multiply every term in the given inequality by -1 or divide every term by -1.  In both cases you must change the direction of the inequality sign.

Example:  Given -3x > 2 + 5y, solve for x.  To do this, multiply all three terms in the inequality by (-1/3), which yields x on the left and -2/3 - (5/3)y on the right.  We must reverse the direction of the inequality sign, so the final answer is  x < -2/3 - (5/3)y.

In statistical hypothesis testing, the P-value is a significant factor. It is the probability of obtaining a test statistic at least as extreme as the one calculated from the data, assuming the null hypothesis to be true. If the null hypothesis is false, the P-value is the probability of a type I error. It is the probability of rejecting the null hypothesis when it is true.

To interpret the P-value correctly, a P-value of 0.054 means that if the null hypothesis is correct, there is a 5.4% probability that the sample will produce a test statistic as extreme as, or more extreme than the one that was observed. If the calculated P-value is higher than the significance level, which is usually 0.05 or 0.01, we cannot reject the null hypothesis.

In the given situation, the sample provides insufficient evidence to reject the owner's claim that the mean weight of Gala apples this year is heavier than usual because the calculated P-value is higher than the significance level. Hence, the correct option is that the P-value suggests that there is not sufficient evidence to reject the null hypothesis.
