Mach is 750 mph and is known as the <br><br><br> The Right Stuff

Wewaii [24]

The correct answer is the first one because we could see reaction 2 has more energy than reaction 3 if you look at the graph and it can't be the second one cause c has more energy than a so the correct one is the first answer

In 1985 a biologist counted 750 pine trees in a 250 hectare forest. Using similar counting techniques, the biologist counted 1,2

Alisiya [41]

Answer:

Suppose that we have a given function f(x)

The average rate of change of the function between two values x₁ and x₂ is given by:

$r = \frac{f(x_2) - f(x_1)}{x_2 - x_1}$

a) We want to find the average (rate) of change on the size of population from 1985 to 1995.

We have that:

f(1985) = 750

f(1995) = 1500

Then we have:

$r = \frac{1500 - 750}{1995 - 1985} = 750/10 = 75$

This means that the population of trees increases, in average, at a rate of 75 trees per year.

b) What is the density of trees each year that they were counted?

This will be equal to the quotient between the number of trees and the area.

1985: number of trees = 750 pines

area = 250 ha

Then the density is:

D(1985) = (750 pines)/(250 ha) = 3 pines/ha

So 1985, there were 3 pines per hectare.

1990: number of trees = 1250 pines

area = 250 ha

Then the density is:

D(1990) = (1250 pines)/(250 ha) = 5 pines/ha

1995: number of trees = 1500 pines

area = 250 ha

The density is:

D(1995) = (1500 pines)/(250 ha) = 6 pines/ha

3) now we want to get the average change between 1985 and 1995 in the density, this will be:

$r = \frac{D(1995) - D(1885)}{1995 - 1985} = \frac{6 pines/ha - 3pines/ha}{10} = 0.3 pines/ha$

So, on average, each year the number of pines per hectare increases by 0.3

Why is it not useful to view science as a set of facts ?

SVETLANKA909090 [29]

If science is to be defined at, science is a systematized body of knowledge. Science is where the organized set of facts were obtained and is used as a tool, model or paradigm to gather such evidential data. Science is not a fact but an existential body in which comprises the study of the anatomy and physiology of a certain object by the means of observation, hypothesis, experimentation, interpretation and conclusion of the gathered facts. Or what others would describe the scientific process.
