Any value in the interval (-∞,-2√5] ∪[2√5,∞) will cause the quadratic equation x2+bx+5 = 0 to have two real number solutions.

Given quadratic equation is:

\(x^{2} +bx+5=0\)

Any equation of the form \(ax^{2} +bx+c=0\) is called a quadratic equation where a≠0.

To have two real number solutions the discriminant of a quadratic equation should be greater than or equal to zero.

\(D\geq 0\)

\(b^{2} -4(1)(5)\geq 0\)

\(b^{2}-20 \geq 0\)

\(b^{2} -(2\sqrt{5}) ^{2}\geq 0\)

\((b+2\sqrt{5} )(b-2\sqrt{5} )\geq 0\)

b∈\((-\infty,-2\sqrt{5}]\)∪\([2\sqrt{5},\infty)\)

Step-by-step explanation:

Area of rectangle = length * width

                             = 6 *5

                             = 30 sq.ft

Area of triangle1 = \(\frac{1}{2}*base*height\)

                           \(= \dfrac{1}{2}*5 * 3\\\\= \dfrac{15}{2}\\\\= 7.5 \ ft^{2}\)

The power delivered by the student's biceps is 51.45 watts (W).

To calculate the power delivered by the student's biceps while doing a pull-up, we use the formula:

Power = Work/Time

Since the physics student lifts her 42 kg body to a distance of 0.25 m, the work done is given by:

Work = Force x Distance

The force exerted by the student is equal to her weight, which is given by:

F = mg

where m = 42 kg (mass of the student) and

g = 9.8 m/s² (acceleration due to gravity)

Therefore,

F = 42 kg x 9.8 m/s²

= 411.6 N (weight of the student)

Hence, the work done by the student is:

Work = Force x Distance

= 411.6 N x 0.25 m

= 102.9 J (joules)

The time taken by the student to complete the pull-up is given as 2 seconds.

Therefore:Time = 2 s

Now we can substitute the values into the formula for power:

Power = Work/Time

= 102.9 J/2 s

= 51.45 W

Step-by-step explanation:

The diagonal of a cube connects two opposite corners.

You can use the diagonal of a cube in a right triangle in which it is the hypotenuse. The legs of the triangle are a diagonal of a face and an edge.

Let the length of the edge be s.

a^2 + b^2 = c^2

\( s^2 + 10^2 = (\sqrt{150})^2 \)

\( s^2 + 100 = 150 \)

\( s^2 = 50 \)

\( s = \sqrt{50} \)

\( s = 5\sqrt{2} \)

s = 7.1

Answer: 7.1 cm

The equation that represents the f(x), in which the amount by which difference between the terms changes are the same, indicating that f(x) is a quadratic function is the option A

A. f(x) = -2·x² - 8·x + 42

A quadratic function is a function that can be expressed using the vertex form of a quadratic equation as follows;

f(x) = a·(x - h)² + k, where, a ≠ 0, and (h, k) is the coordinates of the vertex of the graph of the quadratic function, which is a parabola.

The first difference of the data in the table are;

50 - 48 = 2

48 - 50 = -2

42 - 48 = -6

32 - 42 = -10

The second difference are;

-2 - 2 = -4

-6 - (-2) = -4

-10 - (-6) = -4

The constant second difference indicates that the function is a quadratic function

The symmetry about the point (-2, 50), indicates that the vertex point on the graph is the point (-2, 50)

The vertex form of the quadratic function is therefore;

f(x) = a·(x - (-2))² + 50 = a·(x + 2)² + 50

The point x = 0, indicates that we get; f(0) = a·(0 - (-2))² + 50 = 42

a·(0 - (-2))² = 42 - 50 = -8

a = -8/(0 - (-2))² = -2

The quadratic function is therefore; f(x) = (-2)·(x + 2)² + 50 = -2·(x² + 4·x + 4) - 50

f(x) = -2·(x² + 4·x + 4) - 50 = -2·x² - 8·x - 8 + 50 = -2·x² - 8·x + 42

f(x) = -2·x² - 8·x + 42

Answer:

I believe the slope is 2/3.

Answer:

B    -1/4

Step-by-step explanation:

To find the common ratio, divide any term by the previous term.

1/16 ÷ -1/4 = 1/16 * -4 = -4/16 = -1/4

=====================================================

Explanation:

Pick any term of the sequence that isn't the first term. Divide whatever you picked by the previous term. That will compute the common ratio. This applies to geometric sequences only.

So let's say we pick on term 3 and divide it over term 2. That will get us...

\(r = \left(\text{3rd term}\right) \div \left(\text{2nd term}\right)\\\\r = -\frac{1}{64} \div \frac{1}{16}\\\\r = -\frac{1}{64} \times \frac{16}{1}\\\\r = \frac{-1*16}{64*1}\\\\r = -\frac{16}{64}\\\\r = -\frac{16}{16*4}\\\\r = -\frac{1}{4}\\\\\)

Where r is the common ratio.

As another example, let's say we picked on term 4 and divided it over the third term

\(r = \left(\text{4th term}\right) \div \left(\text{3rd term}\right)\\\\r = \frac{1}{256} \div -\frac{1}{64}\\\\r = \frac{1}{256} \times -\frac{64}{1}\\\\r = \frac{1*(-64)}{256*1}\\\\r = -\frac{64}{256}\\\\r = -\frac{64}{64*4}\\\\r = -\frac{1}{4}\\\\\)

We get the same result. I'll let you try dividing the second term over the first term. You should get r = -1/4 after simplifying.

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

Because the common ratio is r = -1/4, this means that we multiply each term by the common ratio to generate the next term.

For instance,

term 3 = (term 2)*(common ratio)

term 3 = (1/16)*(-1/4)

term 3 = -1/64

The equation of the absolute value function graph is: y = |x - 3| + 5.

The equation, y = a|x – h| + k, represents the equation of an absolute value function in the vertex form, where:

We are given the following from the graph:

Vertex (h, k) = (3, 5)

Plug in the values of h and k into the equation, y = a|x – h| + k:

y = a|x - 3| + 5

A point on the graph is (5, 7). Find the value of a by substituting (x, y) = (5, 7) into y = a|x - 3| + 5:

7 = a|5 - 3| + 5

7 = a|2| + 5

7 = 2a + 5

7 - 5 = 2a

2 = 2a

2/2 = 2a/2

1 = a

a = 1

(C) Regression analysis is the statistical method commonly used to estimate the level and trend in a time series by modeling the relationship between the data and independent variables.

Regression analysis is the statistical method used to estimate the level and trend in a time series. Time series data represents observations taken at different points in time and is commonly used to analyze trends and patterns over time.

Regression analysis allows us to model the relationship between a dependent variable (in this case, the time series data) and one or more independent variables (such as time or other relevant factors). By using regression analysis, we can identify the underlying trend in the time series and estimate its level.

The regression model captures the relationship between the dependent variable (the time series) and the independent variable(s) by fitting a line or curve that best represents the data. This line or curve helps to identify the overall trend and level of the time series.

While moving average, simulation method, covariance analysis, and correlation analysis are useful techniques in analyzing time series data, they are not specifically designed to estimate the level and trend in a time series. Therefore, (C) regression analysis is the most appropriate method for estimating the level and trend in a time series.

The probability of having non-standard food from the food warmer, which is below 74°C, can be determined by calculating the z-score and finding the corresponding area under the normal distribution curve.

To calculate the UCL, the given goal value (16) is multiplied by the Z-score (2), resulting in an Upper Control Limit of 32.

The Mean Absolute Deviation (MAD) cannot be calculated based on the given data. MAD is a measure of dispersion that calculates the average absolute difference between each data point and the mean. However, only one data point (11.3018) is provided, which is not sufficient to compute MAD.

To determine the probability of having non-standard food from the food warmer (temperature below 74°C), we can calculate the z-score by subtracting the mean temperature (78°C) from the critical temperature (74°C) and dividing it by the standard deviation (2°C). This yields a z-score of -2.

Then, we can find the corresponding area under the normal distribution curve using the z-score table or a statistical calculator. The area represents the probability and subtracting it from 1 gives the proportion of food that can be a health hazard.

The remainder is 4.

Step-by-step explanation:

Note: This question is not correctly stated. It is therefore correctly restated before answering the question as follows:

When 17 is divided by k; where k is a positive integer less than 17, the remainder is 3. What is the remainder when the sum of the possible values of k is divided by 17?

The explanation of the answer is now given as follows:

Since k < 17, it implies that the possible values of k must be from between 1 and 16 inclusive.

Between 1 and 16, only 7 or 14 will give a remainder of 3 when either of them is used to divide 17. Therefore, 7 and 14 are the possible values of k.

Therefore, we have:

Sum of the possible values of k = 7 + 14 = 21

Also, we have:

Sum of the possible values of k divided by 17 = 21 / 17 = 1 with a remainder of 4.

Therefore, the remainder is 4 when the sum of the possible values of k is divided by 17.

Answer:

A square pyramid is composed of an eight-sided square base, four triangular sides, five vertices, and five vertices. This pyramid has a square base with a peak at the top. The fact that a square pyramid is a polyhedron was noted.

Step-by-step explanation:

The three-dimensional geometric shape of a square pyramid has a square base and four triangular sides that are joined at the vertex. Five facets make up its polyhedron shape (pentahedron). Four triangles joined at the vertex and a square base make up a square pyramid. Three sides, a square base, and a central vertex characterize the triangle side faces. The tallest point of the pyramid is known as its "apex." The base is represented by the bottom square. Faces are the three triangular vertices of the triangle. When viewed from the bottom up, a pentahedron is a five-sided, three-dimensional shape that resembles a square pyramid.

Let:

x = Pounds of walnuts in the mix.

Each pound of walnuts costs $0.80. thus x pounds of walnuts cost 0.8x dollars.

Each pound of cashews costs $1.25 and the mix will contain 8 pounds of cashews, so the cost is 8*$1.25 = $10

The total cost of the mix is, therefore: 0.8x + 10 dollars.

We are also given the pound of mix costs $1.00 and we have a total of 8 + x pounds, so the total cost of the mix is 1*(8 + x) dollars.

Equating both costs:

0.8x + 10 = 1*(8 + x)

Operating:

0.8x + 10 = 8 + x

Subtracting x and 10:

0.8x - x = 8 - 10

Simplifying:

-0.2x = -2

Answer: y = 5x + 26

Step-by-step explanation:

To find the equation of a line that is perpendicular to the given line y = -1/5x + 1 and passes through the point (-5, 1), we need to determine the slope of the perpendicular line. The given line has a slope of -1/5. Perpendicular lines have slopes that are negative reciprocals of each other. So, the slope of the perpendicular line will be the negative reciprocal of -1/5, which is 5/1 or simply 5. Now, we have the slope (m = 5) and a point (-5, 1) that the perpendicular line passes through.

We can use the point-slope form of a linear equation to find the equation of the line:

y - y1 = m(x - x1)

Substituting the values, we get:

y - 1 = 5(x - (-5))

Simplifying further:

y - 1 = 5(x + 5)

Expanding the brackets:

y - 1 = 5x + 25

Rearranging the equation to the slope-intercept form (y = mx + b):

y = 5x + 26

Therefore, the equation of the perpendicular line that passes through the point (-5, 1) is y = 5x + 26.
