The compound inequality can be expressed as "x > -4 or x ≤ 4."

The correct graph of the solution is:

OC. Solution: x > -4 and x ≤ 4

Let's solve the compound inequality step by step:

x + 7 > 3

Subtract 7 from both sides to isolate x:

x > 3 - 7

x > -4

and, we have,

x - 5 ≤ -1

Add 5 to both sides to isolate x:

x ≤ -1 + 5

x ≤ 4

Now, we have two inequalities for x:

x > -4

x ≤ 4

The compound inequality can be expressed as "x > -4 or x ≤ 4."

The correct graph of the solution is:

OC. Solution: x > -4 and x ≤ 4

The graph will include all values greater than -4 (open circle) and all values less than or equal to 4 (closed circle) on the number line.

The correct representation is:

OC. Solution: x > -4 and x ≤ 4

Graph:

-5 -4 -3 -2 -1 0 1 2 3 4 5

+---|---|---|---|---|---|---|---|---|---+

-4 0 4

The open circle at -4 indicates that x is greater than -4, and the closed circle at 4 indicates that x is less than or equal to 4.

The shaded area between -4 and 4 represents the solution to the compound inequality.

Step-by-step explanation:

The equation of the line tangent to the graph of f defined by g(x) = 4x^3 - 5x + 3 at the point where x = -1 is y = 7x + 11

Given the function of the graph defined as gx) = 4x^3 - 5x + 3.

If x = -1

f(-1) = 4(-1)^3 - 5(-1) + 3.

f(-1) = 4(-1) + 5 + 3

f(-1) = -4 + 8

f(-1) = 4

Hence the coordinate point on the line will be (-1, 4)

Get the slope of the line at x = 1

\(m=\frac{dy}{dx} = 12x^2-5\\m=12(-1)^2-5\\m=12-5\\m=7\)

Get the required equation. The equation of the line in point-slope form is expressed as \(y-y_0=m(x-x_0)\)

\(y-4=7(x+1)\\y-4=7x+7\\y=7x+7+4\\y=7x+11\\\)

Answer:

MSR=100

STQ=80

Step-by-step explanation:

Answer:

see explanation

Step-by-step explanation:

∠ PTS = ∠ NST are vertical angles and are congruent , then

19x + 5 = 17x + 15 ( subtract 17x from both sides )

2x + 5 = 15 ( subtract 5 from both sides )

2x = 10 ( divide both sides by 2 )

x = 5

Then

∠ NST = 17x + 15 = 17(5) + 15 = 85 + 15 = 100° , so

∠ MSR = ∠ NST = 100° ( vertical angles )

--------------------------------------------------------

∠ STQ and ∠ NST are same- side interior angles and sum to 180° , then

∠ STQ + 100° = 180° ( subtract 100° from both sides )

The correct answer is: No, neither method shows that factors are necessary or sufficient.

The methods of agreement and difference are both used in causal inference to analyze the relationship between factors and outcomes. However, neither method alone can determine whether factors are necessary or sufficient conditions.

The method of agreement examines cases where the outcome occurs and compares the presence or absence of different factors. If a factor is consistently present in all cases where the outcome occurs, it suggests that the factor may be related to the outcome. However, this method does not provide information about whether the factor is necessary or sufficient.

On the other hand, the method of difference compares cases where the outcome occurs and cases where it does not, identifying factors that are present in the former but absent in the latter. This method helps identify factors that are associated with the outcome, but it also does not establish whether the factors are necessary or sufficient conditions.

To determine whether a factor is necessary or sufficient, additional evidence and reasoning are required. Additional experiments, data analysis, or theoretical considerations are needed to establish the causal relationship and determine the nature of the factor's influence on the outcome. Hence, "No, neither method shows that factors are necessary or sufficient" is the correct option.

Answer:

Step-by-step explanation:

Using combination, there are 63 different ways to walk up a flight of stairs with eleven steps by taking either one or two stairs at a time.

To determine the number of different ways to walk up a flight of stairs with eleven steps, we can continue the pattern and build our way up from smaller flights of stairs.

For one stair, there is only one way to walk up: (1).

For two stairs, there are two ways to walk up: (1, 1) or (2).

For three stairs, there are three ways to walk up: (1, 1, 1), (1, 2), or (2, 1).

Now let's analyze the patterns we can observe:

When we reach four stairs, we can either take a single step from the previous three stairs (3 ways) or take a double step from the previous two stairs (1 way). This gives us a total of 4 ways.

When we reach five stairs, we can either take a single step from the previous four stairs (4 ways) or take a double step from the previous three stairs (2 ways). This gives us a total of 6 ways.

When we reach six stairs, we can either take a single step from the previous five stairs (6 ways) or take a double step from the previous four stairs (3 ways). This gives us a total of 9 ways.

Continuing this pattern, for seven stairs, we have 4 + 6 = 10 ways.

For eight stairs, we have 6 + 9 = 15 ways.

For nine stairs, we have 9 + 15 = 24 ways.

For ten stairs, we have 15 + 24 = 39 ways.

Finally, for eleven stairs, we have 24 + 39 = 63 ways.

Methods used to summarize or organize characteristics of data are referred to as descriptive methods.

Descriptive methods are used to describe the basic features of a set of data, such as its central tendency (mean, median, mode) and dispersion (range, variance, standard deviation). These methods provide a summary of the data, often through the use of graphical representations such as histograms, bar charts, and scatter plots.

The goal of descriptive methods is to understand the underlying structure of the data, identify patterns, and present the data in a clear and meaningful way.

Descriptive methods do not make inferences about a population based on a sample or draw conclusions about causality.

The possible roots of √9 are +3 and -3.

What is root of a number?

In mathematics, a number's root is the number that, when multiplied by itself, yields the original number. For instance, since 7 x 7=49, the square root of 49 is 7. In this instance, 7 is referred to as the square root of 49 since it must be multiplied twice to produce the number. 3 because

3 x 3 x 3 = 27 is the cube root of 27.

We have to find the possible roots of √9.

The number 9 is not a prime number and is an odd number.

The multiple of nine can be expressed as follows:

1 x 9 = 9

3 × 3 = 9

9 × 1 = 9

You are aware that the number 9 is a multiple of three or that the result of multiplying three times itself is nine. Consequently, the square root of 9 can be expressed as;

\(\sqrt{9} = \sqrt{3*3} = \sqrt{3^2}\)

The square root of a number is cancelled by the square. As a result, when we square the above expression's square root, we obtain.

√9 = ±3

In essence, taking a number's square root yields two root values, one with a +ve symbol and the other with a -ve symbol.

Therefore, we can say that the roots of 9 are +3 and -3, or that the value of the square root of 9 can be expressed as +3 and -3.

Answer:

A: 236 sqaure ft.

B: 4 cans

Step-by-step explanation:

Sure, I can help you with that.

Part A:

The total surface area of a rectangular prism is calculated using the following formula:

Total surface area = 2(lw + wh + lh)

where:

In this case, we have:

Plugging these values into the formula, we get:

Total surface area = 2(8*6+6*5+8*5) = 236 square feet

Therefore, the total surface area of the doghouse is 236 square feet.

Part B:

Since the bottom of the doghouse will not be painted, we only need to paint the top, front, back, and two sides.

The total surface area of these sides is 236-6*8 = 188 square feet.

Therefore,

we need 188 ÷ 50 = 3.76 cans of paint to paint the doghouse.

Since we cannot buy 0.76 of a can of paint, we need to buy 4 cans of paint.

Answer:

A)  236 ft²

B)  4 cans of paint

Step-by-step explanation:

The given diagram (attached) shows the doghouse modelled as a rectangular prism with the following dimensions:

The formula for the total surface area of a rectangular prism is:

\(S.A.=2(wl+hl+hw)\)

where w is the width, l is the length, and h is the height.

To find the total surface area of the doghouse, substitute the given values of w, l and h into the formula:

\(\begin{aligned}\textsf{Total\;surface\;area}&=2(6 \cdot 8+5 \cdot 8+5 \cdot 6)\\&=2(48+40+30)\\&=2(118)\\&=236\; \sf ft^2\end{aligned}\)

Therefore, the total surface area of the doghouse is 236 ft².

\(\hrulefill\)

As the bottom of the doghouse will not be painted, to find the total surface area to be painted, subtract the area of the base from the total surface area:

\(\begin{aligned}\textsf{Area\;to\;be\;painted}&=\sf Total\;surface\;area-Area\;of\;base\\&=236-(8 \cdot 6)\\&=236-48\\&=188\; \sf ft^2\end{aligned}\)

Therefore, the total surface area to be painted is 188 ft².

If one can of paint will cover 50 ft², to calculate how many cans of paint are needed to paint the doghouse, divide the total surface area to be painted by 50 ft², and round up to the nearest whole number:

\(\begin{aligned}\textsf{Cans\;of\;paint\;needed}&=\sf \dfrac{188\;ft^2}{50\;ft^2}\\\\ &= \sf 3.76\\\\&=\sf 4\;(nearest\;whole\;number)\end{aligned}\)

Therefore, 4 cans of paint are needed to paint the doghouse.

Note: Rounding 3.76 to the nearest whole number means rounding up to 4. However, even if the number of paint cans needed was nearer to 3, e.g. 3.2, we would still need to round up to 4 cans, else we would not have enough paint.
