Let f(x)=x2−4. What is the average rate of change of f(x) from −5 to −2 ?

A. -1/7

B. 1/7

C. -7

D. 7

Answers

Answer:

Step-by-step explanation:

To find the average rate of change of the function f(x) from -5 to -2, we need to calculate:

(f(-2) - f(-5))/(-2 - (-5))

First, let's find f(-2) and f(-5):

f(-2) = (-2)^2 - 4 = 0

f(-5) = (-5)^2 - 4 = 21

Substituting these values in the above formula, we get:

(0 - 21)/(-2 + 5) = -21/3 = -7

Therefore, the average rate of change of f(x) from -5 to -2 is -7.

So the answer is (C) -7.

What is the area of a triangle with a base of 5x - 4 and a height of 2x +6?

Answers

The area of the triangle is 5x² + 11x -12 whose base is 5x - 4 and height is 2x + 6.

What is triangle?

A triangle is a two-dimensional geometric shape that is formed by three straight lines that connect three non-collinear points. The vertices are typically denoted by letters, such as A, B, and C. The three angles formed by the sides are also part of the triangle.

According to question:

The formula for calculating a triangle's area is:

Area = 1/2 x Base x Height

Plugging in the given values, we get:

Area = 1/2 x (5x - 4) x (2x + 6)

Simplifying, we get:

Area = 1/2 x (10x² + 22x - 24)

Distributing the 1/2, we get:

Area = 5x² + 11x - 12

Therefore, the area of the triangle is 5x² + 11x - 12.

The three lines are called the sides of the triangle, and the points where the sides meet are called the vertices of the triangle.

What is trigonometry?

Trigonometry is a branch of mathematics that deals with the relationships between the sides and angles of triangles. It is used to study the properties and behavior of triangles, and is also widely used in fields such as engineering, physics, surveying, and navigation. The three main trigonometric functions are sine, cosine, and tangent, which are abbreviated as sin, cos, and tan, respectively. These functions relate the ratios of the sides of a right triangle to the angles of the triangle.  Trigonometry also involves other concepts such as the Pythagorean theorem, which relates the sides of a right triangle, and the unit circle, which is a circle of radius 1 used to define trigonometric functions of angles beyond 90 degrees. Trigonometry is widely used in a variety of applications, such as calculating the heights of buildings and mountains, designing bridges and other structures, and predicting the motion of objects in physics and engineering.

Here,

In a right triangle, the tangent of an acute angle is the ratio of the length of the side opposite the angle to the length of the side adjacent to the angle.

Using this formula, we can find the tangent of angle G:

tan(G) = opposite / adjacent

tan(G) = 6 / 10

tan(G) = 0.6

To find the measure of angle G, we need to take the inverse tangent (or arctangent) of 0.6:

G = tan⁻¹(0.6)

G ≈ 31.0 degrees

Answers

Answer:

  138°

Step-by-step explanation:

You want the measure of the angle at two tangents when they intercept an arc of 42°.

Supplementary angles

The short answer is that the exterior angle x is the supplement of the measure of the arc:

  x = 180° -42°

  x = 138°

Exterior angle

An exterior angle where secants meet is half the difference of the arcs of the circle they intercept. Here, the secants have been located so the corresponding chord length between the near and far circle intercept points have degenerated to zero. That is, they are tangents.

The angle relation still holds:

  x = (long arc - short arc)/2 = ((360° -42°) -42°)/2 = (360° -2·42°)/2

  x = 180° -42° = 138°

Quadrilateral

The tangents, together with their associated radii form a quadrilateral. The angles at the tangents are 90°, and the total of all angles is 360°. This gives us the relation ...

  x + 90° +42° +90° = 360°

  x +42° = 180° . . . . . . . . . . . . . subtract 180°

  x = 180° -42° = 138°

(We solved this with an extra step, so you could see the same "supplementary angles" relationship between x and 42°.)

Para calcular la diferencia en los saldos de la cuenta de jubilación, necesitamos calcular los saldos en ambos casos y luego restarlos.

Para el primer caso, donde la persona comienza a hacer contribuciones anuales a los 40 años, tenemos:

Número de años hasta la jubilación: 60 - 40 = 20 años

Contribución anual: $6,000

Tasa de interés anual: 5%

Usando la fórmula para el valor futuro de una serie de pagos (anualidades) ordinarias, tenemos:

VF = Pmt x [(1 + r)^n - 1] / r

Donde VF es el valor futuro (saldo de la cuenta), Pmt es la contribución anual, r es la tasa de interés anual y n es el número de períodos (en este caso, el número de años hasta la jubilación).

Entonces, para este caso, el saldo de la cuenta sería:

VF = $6,000 x [(1 + 0.05)^20 - 1] / 0.05 = $198,395.72

Para el segundo caso, donde la persona comienza a hacer contribuciones anuales a los 30 años, tenemos:

Número de años hasta la jubilación: 60 - 30 = 30 años

Contribución anual: $6,000

Tasa de interés anual: 5%

Usando la misma fórmula que antes, el saldo de la cuenta sería:

VF = $6,000 x [(1 + 0.05)^30 - 1] / 0.05 = $398,633.09

Entonces, la diferencia en los saldos de la cuenta sería:

$398,633.09 - $198,395.72 = $200,237.37

The y-axis is labeled Frequency and starts at 0 with tick marks every two units up to 10. There is a shaded bar above 1 to 3 that stops at 3, above 2 to 3 that stops at 4, above 5 to 6 that stops at 8, above 6 to 7 that stops at 2, above 8 to 9 that stops at 4 and above 10 to 11 that stops at 8.

Which statement best describes the spread and distribution of the data?

The data is almost symmetric, with a maximum range of 11. This might be because the book fair offers fair prices, so most costumers bought books.

What is a histogram?

A histogram is a type of graph used in statistics to represent the distribution of a set of continuous data. It consists of a set of adjacent bars, where the area of each bar represents the frequency or relative frequency of observations within a specific interval or "bin" of the data.

The x-axis of a histogram shows the range of values for the variable being measured, divided into intervals or bins. The y-axis shows the frequency or relative frequency of observations within each interval or bin. Histograms are commonly used to show the shape, center, and spread of a distribution of data, as well as any potential outliers or gaps in the data.

In the given question, the histogram shows a skewed distribution, where the majority of book sales occurred in the lower intervals (1-3, 2-3, and 5-6) and the frequency decreases as the number of books sold increases. The maximum range of the data is 14 (from the interval 10-11 to the interval 2-3), which suggests a wide spread of book sales across different intervals.

"The data is skewed, with a maximum range of 14. This could be due to the fact that many customers wanted to stock up before the winter." comes the closest to describing the spread and distribution of the data shown in the histogram.

Answers

At the end of the 13-week mosquito season, we would expect to find around 558 mosquitoes in the trap.

It would be unreasonable to continue counting individual mosquitoes after about 13 weeks, since that is usually the end of the mosquito season. This is because, after the 13th week, the number of mosquitoes captured in the trap is likely to decrease significantly, making it pointless to count them individually. At the end of the 13-week mosquito season, the expected number of mosquitoes in the trap can be estimated using a simple exponential decay function.

Assuming the initial number of mosquitoes in the trap is N0 and the rate of decay is k, the number of mosquitoes after t weeks (Nt) can be calculated using the following equation: [tex]Nt = N0 * e-kt.[/tex]

For example, if the initial number of mosquitoes in the trap is 1000 and the rate of decay is 0.2, then the number of mosquitoes after 13 weeks can be estimated as follows:[tex]N13 = 1000 * e-0.2*13 = 558[/tex]

there are 30 aaa batteries in a box and 9 are defective. two batteries are selected without replacement. what is the probability of selecting a defective battery followed by another defective battery

Answers

Therefore, the probability of selecting a defective battery followed by another defective battery is about 12/145 or 8.28%.

What is the probability?

The probability of selecting a defective battery on the first draw is 9/30, or 3/10, since there are 3 defective batteries out of 30 total.

Since one battery has already been drawn, there are now 29 batteries left in the box, and 8 defective batteries remaining. The probability of selecting another defective battery on the second draw, without replacement, is 8/29.

To find the probability of both events happening (selecting a defective battery followed by another defective battery), we multiply the probabilities of each event:

P(defective battery and then another defective battery) = P(defective battery on first draw) × P(defective battery on second draw)

P(defective battery and then another defective battery) = (3/10) × (8/29)

P(defective battery and then another defective battery) = 24/290 = 0.0828 or 8.28%

Describe the shape, center, and spread of the distribution of M-W.2. Find the probability that a randomly selected young man is at least 2 inches taller than a randomly selected young woman.

Answers

We have that, The probability that a randomly selected young man is at least 2 inches taller than a randomly selected young woman is 0.709

How do we find the probability?

1. The shape, center, and spread of the M-W distribution are:Shape: NormalCenter: 4.8 inches (69.3 - 64.5)Spread: The standard deviation of the difference between two normally distributed variables is given by the formula:

[tex]\sigma (M-W) = \sqrt{(\sigma_1^2 + \sigma_2^2)} = \sqrt{(2.8^2 + 2.5^2)} \approx 3.64[/tex]

Let us define [tex]Z = (M - W - 2)/3.64[/tex]. So the probability that a randomly selected young man is at least 2 inches taller than a randomly selected young woman is:

[tex]P(M > W + 2) = P((M - W - 2)/\sigma(M-W) > (- 2)/\sigma (M-W)) = P(Z > -0.55) = 1 - P(Z \leq  - 0.55)[/tex]

Using a standard normal table or a calculator, we find that [tex]P(Z \leq  -0.55) \approx 0.291[/tex]. Therefore, the probability that a randomly selected young man is at least 2 inches taller than a randomly selected young woman is: [tex]P(M > W + 2) \approx  1 - 0.291 = 0.709[/tex].

The shape, center, and spread of the M-W distribution are:

Answer: $3.64

Step-by-step explanation:

At the store, you buy four toys for $1.5, which means you pay $1.5 * 4, or $6.

Then, you calculate the sales tax, which is 6%, which means you multiply $6 by (100% + 6%), or $6*(1.06) which is $6.36.

Finally, if you hand the cashier $10, and you spent $6.36, your change is $10 - $6.36, which is $3.64.

Answer:

To find the area of the given figure, we can divide it into two separate shapes, a rectangle and a triangle, and then add their areas together.

First, we can find the area of the rectangle by multiplying its length and width. From the diagram, we can see that the length of the rectangle is 12 cm and the width is 5 cm.

Area of rectangle = length x width

Area of rectangle = 12 cm x 5 cm

Area of rectangle = 60 cm^2

Next, we can find the area of the triangle by using the formula for the area of a triangle, which is:

Area of triangle = 1/2 x base x height

From the diagram, we can see that the base of the triangle is 5 cm and the height is 8 cm.

Area of triangle = 1/2 x base x height

Area of triangle = 1/2 x 5 cm x 8 cm

Area of triangle = 20 cm^2

Finally, we can find the total area of the figure by adding the area of the rectangle and the area of the triangle:

Total area = area of rectangle + area of triangle

Total area = 60 cm^2 + 20 cm^2

Total area = 80 cm^2

Therefore, the area of the given figure is 80 square centimeters.

Step-by-step explanation:

a researcher compares the effectiveness of two different instructional methods for teaching anatomy. a sample of 116 students using method 1 produces a testing average of 50.3. a sample of 151 students using method 2 produces a testing average of 68.6. assume that the population standard deviation for method 1 is 15.62, while the population standard deviation for method 2 is 17.21. determine the 99% confidence interval for the true difference between testing averages for students using method 1 and students using method 2. step 3 of 3 : construct the 99% confidence interval. round your answers to one decimal place.

Answers

The 99% confidence interval for the true difference between testing averages for students using method 1 and students using method 2 is [15.8, 20.8].

The 99% confidence interval for the true difference between testing averages for students using method 1 and students using method 2 can be calculated using a two-sample t-test.

First, calculate the sample difference in means. Subtract the mean for method 1 (50.3) from the mean for method 2 (68.6) to get 18.3.

Next, calculate the pooled standard deviation, which is the weighted average of the standard deviations for each sample:

Pooled standard deviation = [tex]√(((n1-1)×s12 + (n2-1)×s22)/ (n1+n2-2))[/tex]

n1=116, s12=15.62, n2=151, s22=17.21

Pooled standard deviation = [tex]√(((116-1)×15.62 + (151-1)×17.21)/ (116+151-2))[/tex]
Pooled standard deviation = [tex]√(1422.3788/265)[/tex]

Pooled standard deviation = 4.89

Finally, calculate the 99% confidence interval for the true difference between testing averages for students using method 1 and students using method 2:

99% Confidence Interval = Sample Difference in Means ± (Critical Value) × (Pooled Standard Deviation/√(n1+n2))

99% Confidence Interval =[tex]18.3 ± (2.58) × (4.89/√(116+151))[/tex]

99% Confidence Interval = 18.3 ± 2.50

a 12 cm tall and radius of 10 cm cylinder is filled with 10 cm of water. find a) the rotational speed at which the water just touches the bottom of the cylinder and b) the resulting pressure at points a and b.

Answers

a 12 cm tall and radius of 10 cm cylinder is filled with 10 cm of water.

a) Rotational speed at which the water just touches the bottom of the cylinder:

                  We will use the formula for centripetal force for a liquid with the volume of a cylinder to obtain the rotational speed at which the water just touches the bottom of the cylinder.

         The formula for centripetal force for a liquid with the volume of a cylinder is as follows:

                   F = (ρr²πh)ω²WhereF:

   Centripetal forceρ: Densityr: Radiush : Heightω: Rotational speed Substituting the given values,

       

we get: F = (1000 kg/m³ × (0.1m)² × π × 0.12m)ω²F

                = 377 Nω

                = √(F/m)ω

                = √(377 N/ 10 kg)ω

                = √37.7ω = 6.14 rad/sb)

      Pressure at points A and B:

                                We will use the formula for hydrostatic pressure for a liquid to calculate the pressure at points A and B. The formula for hydrostatic pressure for a liquid is as follows:

                         P = ρgh

  Where,

           P: Pressureρ: Densityg: Acceleration due to gravity: DepthSubstituting the given values for point A,

we get P = 1000 kg/m³ × 9.8 m/s² × 0.1 mP

                = 980 Pa

        Substituting the given values for point B,

we get P = 1000 kg/m³ × 9.8 m/s² × 0.22 mP

                = 2156 Pa

      The resulting pressure at point A is 980 Pa and the resulting pressure at point B is 2156 Pa.
