Answer:

Step-by-step explanation:

The decibel level of the sound of a monster truck is

Further explanation:

Decibel is defined as a unit which is used to measure the relative loudness or intensity of the sound.

In the question it is given that the intensity of the sound of a monster truck is watts per square inch.

The formula which is used to calculate the decibel level of a sound is as follows:

Here, represents the intensity of the sound of a monster truck and represents the threshold intensity of hearing at .

The value of the threshold intensity of hearing at is watts per square meter.

This implies that the valiue of is watts per square meter.

The intensity of the sound of a monster is given in unit of per square inch.

The relation between per square inch and per square meter is as follows:

So, the intensity of a monster truck is converted into per square meter as follows:

This implies that the value of is watts per square meter.

Now, substitute the value of and in the equation .

The approximated value of the above equation is as follows:

From the above calculation it is concluded that the decibel level of the sound of a monster truck is .

How many whole cans can the company make out of each sheet of metal?
klio [65]

Answer:

18

Step-by-step explanation:

Total Surface Area of the Metal Sheet =1000\:in^2

Given a cylinder with diameter 3 Inch and height 4\frac{1}{4} in

To determine how many whole cans can be made, the first step is to find the total surface area of each of the cylindrical can.

Total Surface Area of a cylinder =2\pi r^2+2\pi rh

  • Radius =3÷2=1.5 Inch
  • Height of the can =4\frac{1}{4} in

<u>Total Surface Area of each can </u>

2\pi r^2+2\pi rh=2\pi r(r+h)\\=2*1.5*\pi(1.5+4.25)\\=3\pi *5.75\\=17.25\pi \:in^2

<u>Number of Cans that can be Made </u>

To determine this, we divide the total surface area of the metal sheet by the total surface area of each can.

Number of Cans=Total surface area of the metal sheet÷Total surface area of each can.

=1000 \div 17.25\pi\\=18.45

Therefore, the company can make 18 whole cans from each sheet of metal.

Scientists are monitoring the populations of two insect species in a remote location in Alabama. They estimate that the current
bulgar [2K]

Answer:

2.5e-0.04x = 1.2 + 0.2x

Step-by-step explanation:

Given that:

Insect A:

Initial population, Po = 2.5 million

Rate of decline = 4%

Insect B:

Initial Population (Po) = 1.2 million

Yearly increase = 200,000 = (200,000/1,000,000) = 0.2

For insect A:

P(t) = Po(1 - r)^t = Po*e^-rt

Po*e^-rt = 2.5e^-0.04t ----(1)

For Insect B:

P(t) = Po + (yearly increase) * t

P(t) = 1.2 + 0.2t - - - - - (2)

Equating (1) and (2)

2.5e^-0.04t = 1.2 + 0.2t

Hola, estoy empezando a ver trigonometria queria ver si me pueden ayudar con este problema: Un extraterrestre diminuto pero horr
Kryger [21]

Answer:

El agente debe disparar a un ángulo aproximado de 87.7° con respecto a la horizontal.

Step-by-step explanation:

Sea E la localización del extraterrestre, O, el del hombre de negro, y B, el de la base del edificio. A partir de la información disponible, construimos el diagrama geométrico que indica la presencia de un triángulo rectángulo, el cual puede consultarse en la imagen adjunta.

Podemos determinar el ángulo de disparo mediante la siguiente relación trigonométrica inversa:

A = \tan^{-1} \frac{443\,m}{18\,m}

A \approx 87.7^{\circ}

El agente debe disparar a un ángulo aproximado de 87.7° con respecto a la horizontal.
