It's always a wise choice to create a graph for a question of this nature. Below are the three graphs:
y = x^4 - x^2 Color: Red This represents the original graph
y = x^4 - x^2 - 4 Color Blue This graph has -4 added to it.
y = x^4 - x^2 + 4 Color Green This graph includes 4 added to the original graph.

Which one is accurate? The red and blue graphs do not work. The desired graph should elevate from the original graph. The original graph (red, with nothing added) is incorrect as it intersects the x-axis. The appropriate graph does not intersect there.

The same goes for the blue graph. It also intersects the x-axis. This means only the green option remains.

Response: C

A. F(x) = x^4 - x^2 + 4

B. F(x) = 4 - X^4 - X^4 - X^2

C. F(x) = x^4 - x^2

D. F(x) = x^4 - x^2 - 4

The solution is A

PIT_PIT [9090]

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 achieve simplification, we begin by dividing each function individually

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

According to the properties of indices

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

Thus, the aforementioned expression can be restated similarly

\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 the indices laws

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}

Therefore, \frac{4mn}{m^{-2}n^6} can be regarded as \frac{4m^3}{n^5}

You are ordering shirts for the math club at your school. Short-sleeved shirts cost $10 each. Long-sleeved shirts cost $12 each.
Zina [9144]

Answer:

a. i) Please refer to the attached graph representing the equation $10·x + $12·y = $300

ii) The intercepts indicate the maximum number of short-sleeve (at the x-intercept) and long-sleeve shirts (at the y-intercept) that can be ordered.

Step-by-step explanation:

The details provided are as follows:

Cost of each short-sleeve shirt = $10

Cost of each long-sleeve shirt = $12

Total budget available = $300

The equation for total spending is given by $10·x + $12·y = $300

Where;

x = Number of short-sleeved shirts

y = Number of long-sleeved shirts

Rearranging the equation into slope-intercept form, we have:

$10·x + $12·y = $300

$12·y = $300 - $10·x

y = $300/$12 - $10·x/$12

y = 25 - 5/6·x

Attached is the graph produced using Microsoft Excel

The coordinates that can be used for graph plotting are as follows:

x, y

(0, 25)

(5, 20.83)

(10, 16.67)

(15, 12.5)

(20, 8.33)

(25, 4.17)

(30, 0)

The x-intercept denotes the quantity of short-sleeve shirts purchasable with a $300 budget, while the y-intercept signifies the quantity of long-sleeve shirts achievable under the same budget.

Which of the following data sets indicates a strong negative correlation?
Leona [9244]

Response:

The correct option is: C.

C. {(-2, 4), (-1, 2), (0, 0), (1, -2)}

Detailed explanation:

A strong negative correlation is present--

In this context, a negative correlation signifies that as one variable increases, the other decreases, and vice versa.

This indicates an inverse relationship between the two variables.

Furthermore, this relationship is considered strong if the data points cluster above the line of best fit.

Thus, the data set illustrating a robust negative correlation is:

C. {(-2, 4), (-1, 2), (0, 0), (1, -2)}

In this scenario, the x-values increase consistently by 1 (i.e., -2, -1, 0, 1), while the corresponding values decrease steadily by 2 (i.e., 4, 2, 0, -2).

As a result, a linear correlation emerges with all points positioned above the line, and the line of best fit exhibits a negative slope.

Thus, the data shows a strong negative correlation.
