The statement which is true about the function is that the function is negative for all real values of x where x < –3 or x > –1.

A function assigns the value of each element of one set to the other specific element of another set.

The graph of the function is,

\(f(x) = -(x +3)(x - 1)\)

It is positive, its value is above x-axis. For the function above, the solutions are,

\(x+3=0\\x=-3\\x-1=0\\x=1\)

The value of x is lies between,

\(-3 < x < 1\)

Thus, the statement which is true about the function is that the function is negative for all real values of x where x < –3 or x > –1.

As per the regression equation, the value of intercept coefficient is 1.5707

Regression is a statistical technique used to determine the relationship between an independent variable and a dependent variable.

In this case, the regression statistics provided in table 6 show the results of estimating the model

=> Δln (Sales t) = b0 + b1Δln (Sales t −1) + εt,

where Δln (Sales t) is the change in the natural log of sales for Cisco Systems quarterly observations from 3Q:1991 to 4Q:2000.

The R-squared value of 0.0661 indicates that only about 6.61% of the variation in the change in the log of sales can be explained by the change in the log of sales from the previous quarter.

The standard error of 0.4698 indicates the average deviation between the actual and predicted change in the log of sales.

If the results show that the specification is correct, then the long-run change in the log of sales toward which the series will tend to converge can be determined by the intercept coefficient, which in this case is 1.5707.

Answer:

Distance between -23 & 17 = 40

Step-by-step explanation:

The statement "It took Meredith 43 minutes to run 6 laps." should be written as a rate as follows: Rate = 6/43.

In Science, distance can be defined as the amount of ground that is travelled by a physical object or body over a particular period of time and speed, irrespective of its direction, starting point or ending point.

Mathematically, the distance traveled by a physical object or body can be calculated by using this mathematical expression:

Distance = speed (rate) × time

In this context, we can rewrite the mathematical expression in terms of distance and time as follows;

Speed (rate) = distance/time

Speed (rate) = 6/43.

The value of the profitability index of the project is 2.381.

We know that the growth rate is 4% and the cash flow is $3.7 million, so we can calculate the present value of all future cash flows as follows;

PV of all subsequent cash flows = 3.7 million * (1 + 0.04) / (0.11 - 0.04) = $68.1333 million

Total PV = PV of first-year cash flow + PV of all subsequent cash flows = $3.3154 million + $68.1333 million = $71.4487 million

Finally, we can calculate the profitability index as;

Profitability index = PV of future cash flows / Initial investment = $71.4487 million / $30 million = 2.381

Step-by-step explanation:

This is the expression written in standard form, where the terms are ordered in descending order of the variables' exponents: 2x^3y - 7y^2x - 3x^2 + 12y

To write the expression 2x^3y - 3x^2 - 7y^2x + 12y in standard form, we rearrange the terms in descending order of the variables' exponents.

The standard form of a polynomial is written as follows:

ax^n + bx^m + ... + cx^2 + dx + e

where a, b, c, d, and e are coefficients, and n, m, and so on represent the exponents of the variables.

Applying this to the given expression:

2x^3y - 3x^2 - 7y^2x + 12y

Rearranging the terms, we get:

2x^3y - 7y^2x - 3x^2 + 12y

Answer:

Step-by-step explanation:

Sin A = \(\frac{opposite side}{hypotenuse}=\frac{5}{13}\\\\\)

Cos A = \(\frac{Adjacent side}{hypotenuse}=\frac{12}{13}\)

Tan A = \(\frac{opposite side}{adjacent side}=\frac{5}{12}\)

A = tan⁻¹ (5/12) = 22.61°

Answer:

Step-by-step explanation:

a) Sin A = opposite/hypothenuse

Sin A = 5/13 ≈ 0.3846..

b) Cos A = adjacent/hypothenus

Cos A = 12/13 ≈ 0.9230..

c) Tan A = opposite/adjacent

Tan A = 5/12 ≈ 0.4166..

d) we will use the inverse Sine function

< A = sin^-1(5/13)

< A = sin^-1(0.3846) ≈ 22.62°

Step-by-step explanation:

So, a sample size of around 155 visitors is most likely to yield a sample median of 1,005 visitors, assuming the distribution of visitors is roughly normal.

The formula for calculating the standard error of the median is:

SE = 1.253 * (IQR / √n)

Where SE is the standard error of the median, IQR is the interquartile range (the difference between the 75th percentile and the 25th percentile), and n is the sample size.

Assuming that the distribution of visitors to the zoo each day is roughly normal, we can use the standard error of the median to estimate the range of values within which the sample median is likely to fall. Specifically, we can say that the sample median is likely to fall within:

sample median +/- (z-score * SE)

Where z-score is the number of standard deviations from the mean that corresponds to a particular level of confidence. For example, if we want to be 95% confident that the sample median falls within our estimated range, we would use a z-score of 1.96.

So, to answer your question, we need to find the sample size for which a sample median of 1,005 visitors is likely to fall within the estimated range of values. We can set up an equation like this:

1,005 +/- (1.96 * SE) = 893

Solving for n, we get:

n = (1.253 * IQR / (1.96 * (1,005 - 893)))^2

Using the interquartile range of the distribution (which we don't have, so let's assume it's 500) and plugging in the numbers, we get:

n = 155.14

So a sample size of around 155 visitors is most likely to yield a sample median of 1,005 visitors, assuming the distribution of visitors is roughly normal.

To find the derivative of the function f(x) = x²(x - 9)², we can use the product rule and the chain rule. The derivative of f(x) is f'(x) = 2x(x - 9)² + x²(2(x - 9))(1) = 2x(x - 9)² + 2x²(x - 9).

To find the derivative of a function, we can apply various differentiation rules. In this case, we use the product rule and the chain rule.

Using the product rule, we differentiate each term separately and then sum them up. The first term, x²,

differentiates

to 2x. The second term, (x - 9)², differentiates to 2(x - 9) times the derivative of (x - 9), which is 1.

Applying the chain rule, we multiply the derivative of the outer function, x², by the derivative of the inner function, (x - 9). The derivative of x² is 2x, and the

derivative

of (x - 9) is 1.

Combining these results, we obtain the derivative of f(x) as f'(x) = 2x(x - 9)² + 2x²(x - 9).

To find the average divide total caught by total hours:

Leonard = 40 / 8 = 5 fish per hour

Charlotte = 32/8 = 4 fish per hour

Leonard caught more fish per hour.

Answer:

Step-by-step explanation:

For Leonard: 40/8 = 5 fishes/hr

For Charlotte: 32/8 = 4 fishes/hr

From this, we can identify that Leonard caught more fishes per hour or faster.

A temperature change of 20°C corresponds to a Fahrenheit temperature change of 36°F. The Fahrenheit scale has a different conversion formula than the Celsius scale, resulting in a larger change in degrees for the same temperature difference.

To convert from Celsius to Fahrenheit, we use the formula: F = (C * 9/5) + 32, where F represents the temperature in Fahrenheit and C represents the temperature in Celsius.

In this case, the temperature change is given as 20°C. To find the corresponding Fahrenheit temperature change, we apply the conversion formula: F = (20 * 9/5) + 32 = 36 + 32 = 68°F.

Therefore, a temperature change of 20°C corresponds to a Fahrenheit temperature change of 68°F. Among the given answer choices, the closest option is 36°F.
