The scatterplot shows the number of beach visitors and the average daily temperature. Based on the scatterplot, what is the best

Lady_Fox [76]

Answer:

Option B (350) is the correct answer.

Explanation:

Given:

The temperature is "88°F" i.e., x.

Let number of visitors be "y".

Let the two points will be:

84,225 = (x₁, y₁)

92, 450 = (x₂, y₂)

As we know,

⇒ $y-y_{1}=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}(x-x_{1})$

On substituting the values, we get

⇒ $y-225=\frac{450-225}{92-84}(88-84)$

⇒ $y=337.5$

So that alternative B is the appropriate choice.

You are going sledding with your friends, sliding down a snowy hill. Friction can't be ignored. Riding solo on your sled, you ha

Musya8 [376]

If you let a friend ride with you, increasing the mass does increase the net force on the system, but it also increases the inertia. a=Fnetm. Since both the net force and mass are increased they still cancel, leaving the acceleration the same.

<h3>Further explanation </h3>

Inertia is the tendancy of a moving object to keep moving in a straight line or of any object to resist a change in motion.

According to the picture below, we choose x-direction parallel to the inclined surface. Our positive direction is to the right. Hence, we will calculate the acceleration when riding solo first:

$\Sigma F_x = mg sin \theta - F_k = m a_x\\mg sin \theta - F_k = m a_x\\a_x = \frac{mg sin \theta - F_k }{m} ... (1)\\$
