Given the new regression model, which of the following statements is true? As the number of retail stands increases by one, the

daily revenue increases by $2,298.36 on average. As the number of retail stands increases by one, the daily revenue increases by $2,298.36 on average, provided that the number of female visitors and food stands remains constant. As the number of female visitors increases by ten, the daily revenue increases by $29.34 on average. As the number of female visitors increases by ten, the daily revenue increases by $29.34 on average, provided that the number of retail stands and food stands remains constant.

Answer:

As the number of retail stands increase by one, the daily revenue increases by $2,298.36 on average, provided that the number of female visitors and food stands remains constant.

Step-by-step explanation:

This is gross relationship of regression model, multiple regression model describes net relationship. The net effect on number of retail stands on daily revenue. The average increase in daily revenue as the number of retail stands increases by one while other variables remains constant.

vodomira [7]

Answer: x^2=32y


Step-by-step explanation:

Given:  A mirror with a parabolic cross section is used to collect sunlight on a pipe located at the focus of the mirror.

The pipe is located 8 inches from the vertex of the mirror.

Assume the vertex is at the origin.

If the parabola opens upwards

then the coordinates of focus= (0,8)

We know that equation of parabola with focus (0,a) and open upards is of the form (vertex=(0,0)) is

x^2=4ay

Substitute the value of a=8 in equation, we get

x^2=4\times8y

\Rightarrow\ x^2=32y

Therefore, equation of the parabola that models the cross section of the mirror is x^2=32y

Which represents a quadratic function? f(x) = −8x3 − 16x2 − 4x f (x) = three-quarters x 2 + 2x − 5 f(x) = StartFraction 4 Over x
tatyana61 [14]

Answer:

2.\ f(x) = \frac{3}{4}x^2 + 2x - 5

Step-by-step explanation:

Given

f(x) = -8x^3 - 16x^2 - 4x\\f(x) = \frac{3}{4}x^2 + 2x - 5\\f(x) = \frac{4}{x^2} - \frac{2}{x} + 1\\f(x) = 0x^2 - 9x + 7

Required

Which of the above is a quadratic function

A quadratic function has the following form;

ax^2 +bx + c = 0 \ where \ a\neq 0

So, to get a quadratic function from the list of given options, we simply perform a comparative test of each function with the form of a quadratic function

1.\ f(x) = -8x^3 - 16x^2 - 4x

This is not a quadratic function because it follows the form f(x) = ax^3 + bx^2 + c and this is different from ax^2 +bx + c = 0 \ where \ a\neq 0

2.\ f(x) = \frac{3}{4}x^2 + 2x - 5

This function has an exact match with ax^2 +bx + c = 0 \ where \ a\neq 0

By comparison; a = \frac{3}{4}\ b = 2\ and\ c = -5

3.\ f(x) = \frac{4}{x^2} - \frac{2}{x} + 1

This is not a quadratic function because it follows the form f(x) = \frac{a}{x^2} + \frac{b}{x} + c and this is different from ax^2 +bx + c = 0 \ where \ a\neq 0

4.\ f(x) = 0x^2 - 9x + 7

This is not a quadratic function because it follows the form f(x) = ax^2 +bx + c = 0\ but\ a = 0

Unlike the quadratic function where a\neq 0

So, from the list of given options, only 2.\ f(x) = \frac{3}{4}x^2 + 2x - 5 satisfies the given condition

Gennadij [26K]

Question

Which expression is equivalent to \frac{4mn}{m^{-2}n^6}. Assuming m \neq 0; n\neq 0

Answer:

\frac{4m^3}{n^5}

Step-by-step explanation:

Given

\frac{4mn}{m^{-2}n^6}

Required:

Simplify

To simplify this, we start by splitting each individual function

\frac{4mn}{m^{-2}n^6} = \frac{4m}{m^{-2}} * \frac{n}{n^6}

From laws of indices

\frac{a^x}{a^y} = a^{x-y}

SO, the above expression can also be expressed the same way

\frac{4m}{m^{-2}} * \frac{n}{n^6} = 4m^{1-(-2)} * n^{1-6}

\frac{4m}{m^{-2}} * \frac{n}{n^6} = 4m^{1+2)} * n^{1-6}

\frac{4m}{m^{-2}} * \frac{n}{n^6} = 4m^{3} * n^{-5}

From laws of indices,

a^{-x} = \frac{1}{a^x}

So,

\frac{4m}{m^{-2}} * \frac{n}{n^6} = 4m^{3} * \frac{1}{n^5}

\frac{4m}{m^{-2}} * \frac{n}{n^6} = \frac{4m^3}{n^5}

Hence, \frac{4mn}{m^{-2}n^6} is equivalent to \frac{4m^3}{n^5}
