Jason ran 7/8 of a mile in 12 minutes. How many miles can Jason run in 1 hour

Answer:

D. <B = 141°

Step-by-step explanation:

The sum of interior angles of a polygon is

(n-2)*180, where n is the number of sides!

Sum of angles for our polygon that has 7 sides must be:

(7-2) *180 = 5*180 = 900

Sum of angles that are in the picture are:

120+129+130+142+90+148+ <B = 759 + <B

<B = 900 -759 = 141°

Check our work:

120°+129°+130°+142°+90°+148°+ 141° = 900°✅

The correct option is B) FDE and GDH, as their corresponding angles have the same intercepted arc and, therefore, are congruent.

To determine which angles are congruent in circle D, we need to analyze the given information about the measures of minor arcs. Since minor arcs are measured in degrees, we can use the following properties:

1. When two arcs are congruent, their corresponding central angles are also congruent.

2. The measure of a central angle is equal to the measure of its intercepted arc.

Given these properties, let's examine the answer choices:

A) EDH and FDG: We cannot determine their congruency based solely on the measures of the minor arcs.

B) FDE and GDH: These angles have the same intercepted arc, so they are congruent.

C) GDH and EDH: The intercepted arcs for these angles are different, so they are not congruent.

D) GDF and HDG: These angles have the same intercepted arc, so they are congruent.

Therefore, the correct option is B) FDE and GDH, as their corresponding angles have the same intercepted arc and, therefore, are congruent.

We can use Coulomb's law to calculate the magnitude of the electric field at a distance r away from a point charge Q:

E = k * Q / r^2

where k is Coulomb's constant, Q is the charge of the point charge, and r is the distance from the point charge.

In this problem, we have a point charge Q of -10 nC located at (1.2 cm, 0 cm), and we want to find the x-component of the electric field at a distance r = 5.3 cm away at position (-4.1 cm, 0 cm).

To find the x-component of the electric field, we need to use the cosine of the angle between the electric field vector and the x-axis, which is cos(180°) = -1.

So, the x-component of the electric field at position (-4.1 cm, 0 cm) is:

E_x = - E * cos(180°) = - (k * Q / r^2) * (-1)

where k = 9 x 10^9 N*m^2/C^2 is Coulomb's constant.

Substituting the given values, we get:

E_x = - (9 x 10^9 N*m^2/C^2) * (-10 x 10^-9 C) / (0.053 m)^2

E_x ≈ -30,566.04 N/C

Rounding this to two significant figures and including the appropriate units, we get:

The x-component of the electric field is about -3.1 x 10^4 N/C (to the left).

The total revenue from adult ticket sales (10a) must be greater than or equal to $1200.

Let's represent the number of student tickets sold as 's' and the number of adult tickets sold as 'a'.

The revenue from student ticket sales can be calculated as 7.50s, and the revenue from adult ticket sales can be calculated as 10a.

To satisfy the constraint that the drama club must make no less than $1200, we can write the following inequality:

7.50s + 10a ≥ 1200

This inequality states that the total revenue from student ticket sales (7.50s) plus the total revenue from adult ticket sales (10a) must be greater than or equal to $1200.

This inequality ensures that the ticket sales generate enough revenue to cover the show's costs. The drama club needs to sell enough tickets, both student and adult, to meet or exceed the minimum revenue requirement of $1200.

Answer:

  ∠E = ∠A = 34°; ∠AFB = ∠DFE = 107°-34° = 73°

Step-by-step explanation:

Here's where I'd go next.

73° (∠EDA) is exterior to ΔDAC, so is the sum of remote interior angles A and C. That is, ...

  ∠C + ∠A = 73°

  ∠C = 73° -∠A = 73° -39° = 34°

Triangle CBE is given as isosceles, so its base angles C and E are congruent, both 34°.

Exterior angle CDF is the sum of remote interior angles DEF and DFE, so we have ...

  107° = 34° +∠DFE

  ∠DFE = 107° -34° = 73°

The angle we just found (∠DFE) is a vertical angle with ∠AFB, so has the same measure.

  ∠AFB = 73° . . . . vertical angle with ∠DFE

_____

In summary, it looks like we have added some steps to the derivation:

  4. ∠A = 34° . . . . exterior angle theorem (∠A +39° = 73°)

  5. ∠E = ∠A = 34° . . . . definition of isosceles triangle

  6. ∠DFE = 73° . . . . exterior angle theorem (∠E +34° = 107°)

  7. ∠AFB = 73° . . . . vertical angles

Any sort of math problem solving has you work from what you know to what you need to know by making use of previously learned relationships between the bits of information you have. Here, you really only need to know (a) angles of a linear pair total 180°; (b) angles in a triangle total 180°; (c) angles opposite congruent sides in a triangle are congruent.

The correct option is b) Label.

In a chart, each data point, bar, slice, and so on has a unique label. This label is used to identify and differentiate the different elements within the chart. It provides a clear and concise description of what each element represents.

For example, in a bar chart that shows the sales of different products, each bar would have a label indicating the specific product it represents. This allows the viewer to easily understand which product corresponds to each bar.

The label is crucial in making the chart understandable and meaningful. Without it, the chart would be confusing and difficult to interpret. It helps to provide context and clarity to the data being presented.

While color, size, and position can also be used to distinguish between elements in a chart, they do not provide the same level of specificity as a label. Color, for instance, may be used to represent different categories, but it does not provide specific information about each individual element.

In summary, the unique label assigned to each data point, bar, slice, or other element in a chart is what helps identify and differentiate them. It provides a clear description of what each element represents, making the chart more understandable and meaningful.

Answer:

Step-by-step explanation:

The factor of 2 in the Virial theorem accounts for the balance between average kinetic energy and average potential energy in a system. Without this factor, the theorem would inaccurately represent the energy equilibrium.

The Virial theorem is a fundamental principle in physics that relates the average kinetic energy (KE) of a system to its average potential energy (PE). The theorem states that in a stable system, the average kinetic energy is equal to minus one-half times the average potential energy, or KE = -1/2 PE. The factor of 2 in the theorem is crucial for this relationship to hold.

To understand the significance of this factor, let's consider a hypothetical scenario where there is no factor of 2 in the Virial theorem, meaning KE = PE. In this case, the theorem would suggest an equal balance between kinetic and potential energies. However, this assumption contradicts our understanding of typical astrophysical systems.

Astrophysical systems, such as galaxies, stars, or even gas clouds, often possess a significant amount of gravitational potential energy. If there were no factor of 2, the theorem would imply that the kinetic energy of these systems is equal to the gravitational potential energy. This would imply that the system is on the verge of collapse or expansion, which is not usually the case for stable systems.

The factor of 2 in the Virial theorem accounts for the fact that the average kinetic energy of particles in a system is typically twice as large (in magnitude) as the average potential energy. This factor arises due to the virialization process, where particles oscillate between kinetic and potential energy as they interact with each other. The factor of 2 allows for a more accurate representation of the balance between these energies in a stable system.

In conclusion, the factor of 2 in the Virial theorem is essential to accurately describe the relationship between the average kinetic and potential energies in astrophysical systems. Without this factor, the theorem would fail to capture the typical energy balance observed in stable systems.

The Virial theorem is a powerful tool used in various fields of astrophysics, including the study of galaxies, star clusters, and even the dynamics of gas in the interstellar medium. Understanding its derivation and applications can provide deeper insights into the behavior and evolution of these astronomical systems.

Additionally, exploring the concept of virialization and how it relates to the factor of 2 in the Virial theorem can shed light on the dynamical processes occurring within these astrophysical environments.

f"(x) = 12x² + 12x + 16

f"(5) = 12(5)² + 12(5) + 16

The derivative of a polynomial function f(x) can be found by differentiating each term of the polynomial separately. In this case, the given function is f(x) = x^4 + 2x^3 + 8x^2 + 4x. To find the derivative f'(x), we differentiate each term with respect to x. The derivative of x^n, where n is a constant, is nx^(n-1). Applying this rule, we get:

f'(x) = 4x^3 + 3(2x^2) + 2(8x) + 4 = 4x^3 + 6x^2 + 16x + 4

To find the value of f'(5), we substitute x = 5 into the derivative function:

f'(5) = 4(5)^3 + 6(5)^2 + 16(5) + 4 = 500

The second derivative, f''(x), is the derivative of the first derivative f'(x). To find f''(x), we differentiate f'(x) with respect to x:

f"(x) = 12x^2 + 6(2x) + 16 = 12x^2 + 12x + 16

To find the value of f''(5), we substitute x = 5 into the second derivative function:

f"(5) = 12(5)^2 + 12(5) + 16 = 376

In summary:

f'(x) = 4x^3 + 6x^2 + 16x + 4

Answer:

1a) \(m = \frac{60}{ \sqrt{31 - 2n} } \)

b) 8.47 (3 s.f.)

Step-by-step explanation:

If y is inversely proportional to x, then \(y = \frac{k}{x} \), where k is a constant.

Since m is inversely proportional to \( \sqrt{31 - 2n} \),

\(m = \frac{k}{ \sqrt{31 - 2n} } \), where k is a constant.

When n=3,

\(m = \frac{k}{ \sqrt{31 - 2(3)} } \\ m = \frac{k}{ \sqrt{31 - 6} } \\ m = \frac{k}{ \sqrt{25} } \\ m = \frac{k}{5} \)

when n=11,

\(m = \frac{k}{ \sqrt{31 - 2(11)} } \\ m = \frac{k}{ \sqrt{31 - 22} } \\ m = \frac{k}{ \sqrt{9} } \\ m = \frac{k}{3} \)

Since the sum of the values of m when n=3 and n=11 is 32,

\( \frac{k}{3} + \frac{k}{5} = 32 \\ \frac{5k}{15} + \frac{3k}{15} = 32 \\ \frac{8k}{15} = 32 \\ 8k = 32(15) \\ 8k = 480 \\ k = 60\)

a) \(m = \frac{60}{ \sqrt{31 - 2n} } \)

b) When m=16,

\(16 = \frac{60}{ \sqrt{31 - 2n} } \\ 16( \sqrt{31 - 2n} ) = 60 \\ \sqrt{31 - 2n } = 60 \div 16 \\ \sqrt{31 - 2n} = 3.75 \\ 31 - 2n = 3.75^{2} \\ 31 - 14.0625 = 2n \\ 2n = 16.9375 \\ n = 8.47 \: (3 \: s.f.)\)

To find the amount of flour poured into the tank in the first 2.5 seconds, we need to calculate the definite integral of the given rate function F(t) over the interval [0, 2.5].

The rate at which flour is poured into the tank is given by F(t) = 36/1, in pounds per second. Integrating this function will give us the total amount of flour poured into the tank over the given time interval.

The integral of F(t) with respect to t can be calculated as follows:

∫ F(t) dt = ∫ (36/1) dt

Integrating the constant term 36 gives:

= 36t

To find the definite integral over the interval [0, 2.5], we substitute the upper and lower limits of integration:

= 36(2.5) - 36(0)

= 90 - 0
