The height of the given pentagonal such that its base area is 42 units² will be 7.9 units.

Volume is the scalar quantity of any object that specified occupied space in 3D.

For example, the space in our room is referred to as volume.

The volume of the cuboid = length × height × width.

Suppose that height of the pentagonal is h.

Volume = base area x height h

331.8 = 42 x h

h = 7.9 units.

Hence "The height of the specified pentagonal will be 7.9 units such that its base area is 42 units²".

The 25° angle the light ray makes with the normal, B which is the angle of incidence, according to the laws of reflection, indicates that the angle of reflection, which is the angle the reflected ray makes with the normal, C, is 25°

The laws of reflection states that (1) The angle of incidence and the angle of reflection have the same value (2) The incident ray, the reflected ray and the normal are coplanar (3) The refracted ray is on the opposite side of the normal with regards to the incident ray.

The law of reflection states that the angle the in of reflection and the angle of incidence are equal; [tex]\theta_i = \theta_r[/tex]

The angle the incident ray makes with the normal of the plain mirror and the angle the reflected ray makes with the normal are the same.

The angle the incident ray in the diagram of the question makes with the normal line segment, B = 25°

The angle the reflected ray makes with the normal line segment = C

Therefore, according the to the laws of reflection, we get;

Answer:

The possible values of the angle \alpha that satisfy the given equation are the angles in the range [0, 60] degrees or the angles in the range [300, 360] degrees. This is because we showed that the value of cos(\alpha) must be less than or equal to 1/\sqrt{3} in order for the equation to hold.

Step-by-step explanation:

It looks like you have entered some LaTeX code in your question, but it is not properly formatted. Here is the correct way to enter the equation:

cos(\alpha) + \frac{1}{\sqrt{3}} \cdot sin(\alpha) = 1

To solve this equation, we can use the identity cos^2(\alpha) + sin^2(\alpha) = 1. We can rewrite the left-hand side of the equation as follows:

cos^2(\alpha) + \frac{1}{3} \cdot sin^2(\alpha) = 1

Then, we can solve for sin^2(\alpha):

sin^2(\alpha) = 3 \cdot (1 - cos^2(\alpha))

Since sin^2(\alpha) is nonnegative, we know that cos^2(\alpha) must be less than or equal to 1/3. This means that cos(\alpha) must be less than or equal to 1/\sqrt{3}. Therefore, the possible values of \alpha that satisfy the given equation are the angles in the range [0, 60] degrees or the angles in the range [300, 360] degrees.

Note that this solution assumes that the angle \alpha is measured in degrees. If the angle is measured in radians, then the range of possible values for \alpha will be different.

Answer:

  Ms finch has the higher ratio

Step-by-step explanation:

Given ratios 2 : 6 and 3 : 5, you want to know which is greater.

There are several ways to compare ratios. You can express them over a common denominator, compare them to a common value, convert them to decimal, subtract one from the other.

  2 : 6 vs 3 : 5 = 10 : 30 vs 18 : 30

3 : 5 is greater than 2 : 6, so Ms finch has the higher ratio.

  2 : 6 vs 3 : 5

We can compare each of these to 1/2.

  2 : 6 < 3 : 6 = 1/2

  3 : 5 > 2.5 : 5 = 1/2

3 : 5 is greater than 2 : 6, so Ms finch has the higher ratio.

  2 : 6 ≈ 0.333

  3 : 5 = 0.600

3 : 5 is greater than 2 : 6, so Ms finch has the higher ratio.

  2/6 -3/5 = (10 -18)/(30) = -8/30 so the second ratio is higher

3 : 5 is greater than 2 : 6, so Ms finch has the higher ratio.

A seismograph station in a particular city might not record any data about some earthquakes because the ground motion it produced might not be strong enough to be detected by the station.

Seismograph stations measure ground motion, and the farther an earthquake is from a station, the weaker the ground motion it produces. If an earthquake is too far away, the ground motion it produces may be too weak to be detected by the seismograph station.

Additionally, if the earthquake occurred in a direction that was not directly aligned with the seismograph station, the ground motion it produced might not be strong enough to be detected by the station.

Step-by-step explanation:

Let's call the initial distance from the jet to the airport $x$. We are told that $x = 5$ miles.

Let's call the initial ground distance from the projection of the jet onto the ground to the airport $y$. We are told that $y = 4$ miles.

Let's call the rate at which the distance from the jet to the airport is increasing $v_x$. We are told that $v_x = 180$ miles/hour.

Let's call the rate at which the ground distance from the projection of the jet to the ground to the airport is increasing $v_y$. We are told that $v_y = 150$ miles/hour.

We want to find the vertical speed of the jet at this moment in time. Let's call this quantity $v_z$.

Since the jet is flying in the eastward direction, we can use the Pythagorean theorem to relate the three sides of the right triangle formed by the jet, the projection of the jet onto the ground, and the airport. Specifically, we have

$$x^2 = y^2 + z^2$$

where $z$ is the vertical distance from the jet to the ground (i.e., the height of the jet above the ground).

Since the distance from the jet to the airport and the ground distance from the projection of the jet to the airport are both increasing, we can take the derivative of both sides of the equation above to find the rate of change of $z$ with respect to time. This gives us

$$2x \frac{dx}{dt} = 2y \frac{dy}{dt} + 2z \frac{dz}{dt}$$

where $t$ is time.

We are given the values of $x$, $y$, $v_x$, and $v_y$, so we can plug these values into the equation above to solve for $v_z$. This gives us

$$2 \cdot 5 \cdot 180 = 2 \cdot 4 \cdot 150 + 2z \frac{dz}{dt}$$

Solving for $\frac{dz}{dt}$, we get

$$\frac{dz}{dt} = \frac{2 \cdot 5 \cdot 180 - 2 \cdot 4 \cdot 150}{2z}$$

We are told that $z = x - y$, so we can plug this into the equation above to find $\frac{dz}{dt}$. This gives us

$$\frac{dz}{dt} = \frac{2 \cdot 5 \cdot 180 - 2 \cdot 4 \cdot 150}{2(x-y)}$$

Substituting the values of the known quantities, we get

$$\frac{dz}{dt} = \frac{2 \cdot 5 \cdot 180 - 2 \cdot 4 \cdot 150}{2(5-4)} = \frac{180}{2} = 90$$

Therefore, the vertical speed of the jet at this moment in time is $v_z = 90$ miles/hour.

The vertical speed of the jet is approximately 300 miles/hour.

Velocity is the pace and direction of an item's movement, whereas speed is the time rate at which an object is traveling along a route.

Let's call the distance from the jet to the airport "d" and the height of the jet "h". Then we have two related rates:

d is increasing at a rate of 180 miles/hour.

The horizontal distance is increasing at a rate of 150 miles/hour.

Using the Pythagorean theorem, we can relate these two distances:

d² = h² + 4²

Taking the derivative of both sides with respect to time, we get:

2d(dd/dt) = 2h(dh/dt)

Simplifying, we get:

dd/dt = (h/d)(dh/dt)

We're looking for the vertical speed of the jet, which is dh/dt. We can solve for this by plugging in the given values:

d = 5 miles

dd/dt = 180 miles/hour

h² + 4² = 5² (from the Pythagorean theorem)

dh/dt = ?

Solving for h, we get:

h² = 5² - 4² = 9

h = 3 miles

Now we can plug in all the values and solve for dh/dt:

dh/dt = (dd/dt)(d/h) = (180 miles/hour)(5 miles/3 miles) ≈ 300 miles/hour

The required value of c is 16 which is the correct answer that would be an option (C).

In triangle LMN, m∠L = (4c + 47). If the exterior angle to L measures 69°,

The measure of an exterior angle of a triangle is equal to the sum of the measures of the two interior angles that are not adjacent to it.

In the case of triangle LMN, we can use the given information to write the following equation:

⇒ 180 - 69 =  (4c + 47)

⇒ 111 = 4c + 47

⇒ 4c = 111- 47
