1. The pollution level in the center of a city at 6 am is 30 parts per million and it
Nady [450]

Answer:

a) y(t) = 30 + 25t

b) The pollution level at 4 o'clock in the afternoon​ is of 280 parts per million.

Step-by-step explanation:

The pollution level in the center of a city at 6 am is 30 parts per million and it grows in linear fashion by 25 parts per million every hour.

This means that the pollution in t hours after 6 am is given by:

y(t) = 30 + 25t, which is the answer to question a.

b. The pollution level at 4 o'clock in the afternoon​

4 in the afternoon is 10 hours after 6 am, so this is y(10).

y(10) = 30 + 25*10 = 30 + 250 = 280

The pollution level at 4 o'clock in the afternoon​ is of 280 parts per million.

Someone please help me with this
goldfiish [28.3K]

Answer:

<em>50° is the correct answer</em>

Step-by-step explanation:

<u>Right Triangles</u>

The right triangles are identified because they have an internal angle of 90°. The basic trigonometric ratios can be used to find angles and side lengths as needed.

We have a right triangle with the following characteristics:

The hypotenuse is 13 units long

The indicated angle is opposite to the leg of 10 units long.

When we know the length of the opposite side, we use the sine ratio. Let's call θ to the required angle:

\displaystyle \sin\theta=\frac{\text{opposite side}}{\text{hypotenuse}}

\displaystyle \sin\theta=\frac{10}{13}

Using a calculator set in mode <em>degrees</em>, the angle is:

\theta=\sin^{-1}\frac{10}{13}

\theta\approx 50.3^\circ

First choice: 52° is not correct because is not a good approximation to 50.3°

Second choice:38° is not correct because is not a good approximation to 50.3°

Third choice: 50° is a good approximation to 50.3°. Correct Answer

Fourth choice: 40° is not correct because is not a good approximation to 50.3°
