"Of all the environmental impacts of the study projections, deforestation probably poses the most serious problems for the world, particularly for the developing world."
Global 2000
"It has been predicted that within the next 25-30 years, most of the humid tropical forest as we know it, will be transformed into unproductive land, and the deterioration of the savannah into desert will continue at ever-increasing speed."
As you read this sentence, 50 to 100 acres of primary tropical forests will be eliminated, disrupted, degraded or impoverished. Yearly, an area of tropical forest the size of Great Britain is "converted" from an area equal to the size of Europe.
If present trends continue, by the year 2000, all tropical forests, with the exception of two areas - the western Brazilian Amazon and Central Africa - will have been destroyed. Since 1950, according to the U.N. Food and Agriculture Organization (FAO), half of the world's forests have disappeared. Latin America has lost 37 percent of its tropical forests; Central America, 66 percent; Southeast Asia, 38 percent; Central Africa, 52 percent. Nearly 20 million acres are destroyed annually.
As areas of tropical forests are destroyed or degraded, tribal groups are forced to change their resource base. In some cases they move into areas occupied by other groups, straining the area's resources. In other cases they are forced to relocate outside of forests, permanently altering their way of life by converting to agriculture or to cash employment. Rarely are the rights of these groups to the lands they occupy recognized. Further, their intimate knowledge of the area's resources and how to manage them are nearly always ignored.
Millions of indigenous people live in tropical moist forests which cover some 3.6 million square miles in 70 countries. More than 80 percent of these forests are found in Bolivia, Brazil, Colombia, Gabon, Indonesia, Malaysia, Peru, Venezuela, and Zaire, while 30 additional countries contain sufficient tracts to have significant ecological and biotic values. If these areas are to be managed effectively into the next century, the indigenous peoples that inhabit them should be consulted.

add those up to get 3y² - 10 y + 3
multiply all terms of the result by 2
Answer:
6y^2 - 20y + 6.
Step-by-step explanation:
2(3y − 1)(y − 3)
= 2 [ 3y(y - 3) - 1(y - 3)]
= 2 (3y^2 - 9y - y + 3)
= 2(3y^2 - 10y + 3)
= 6y^2 - 20y + 6.
Which of the following equations represents Exponential Decay?
y=−3x+5
y=3(0.8)x
y=−3x−5
y=0.8(3)x
Answer:
y=3(0.8)x
Step-by-step explanation:
An exponential function is a function of the form;
[tex]y=ab^{x}[/tex]
The explanatory variable x is the exponent, a is the initial value and b the base of the exponential function.
The function is said to be an exponential decay function if the base is between 0 and 1;
0<b<1
Therefore, y=3(0.8)^x is the required function. The values of y become smaller as x increases.

An anthropologist finds that a prehistoric bone contains less than 8.1% of the amount of Carbon-14 the bones would have contained when the person was alive. How long ago did the person die? (The constant for Carbon-14 is 0.00012.)
19,000 years
20,944 years
21,048 years
23,028 years
Answer:
20,944 years
Step-by-step explanation:
The formula you use for this type of decay problem is the one that uses the decay constant as opposed to the half life in years. We are given the k value of .00012. If we don't know how much carbon was in the bones when the person was alive, it would be safer to say that when he was alive he had 100% of his carbon. What's left then is 8.1%. Because the 8.1% is left over from 100% after t years, we don't need to worry about converting that percent into a decimal. We can use the 8.1. Here's the formula:
[tex]N(t)=N_{0} e^{-kt}[/tex]
where N(t) is the amount left over after the decay occurs, [tex]N_{0}[/tex] is the initial amount, -k is the constant of decay (it's negative cuz decay is a taking away from as opposed to a giving to) and t is the time in years. Filling in accordingly,
[tex]8.1=100e^{-.00012t}[/tex]
Begin by dividing the 100 on both sides to get
[tex].081=e^{-.00012t}[/tex]
Now take the natural log of both sides. Since the base of a natual log is e, natural logs and e "undo" each other, much like taking the square root of a squared number.
ln(.081)= -.00012t
Take the natual log of .081 on your calculator to get
-2.513306124 = -.00012t
Now divide both sides by -.00012 to get t = 20,944 years

How do you do this problem?
Answer:
[tex]\boxed{x = 8}[/tex]
Step-by-step explanation:
1. Jump discontinuity
In the graph, you can see that the left-hand limit of g(x) as x⟶ 8 is 3 and the right-hand limit is -3.
When the left- and right-hand limits at x = 8 exist but are different, we say that g(x) has a jump discontinuity at [tex]\boxed{\textbf{x = 8}}[/tex].
2. Other discontinuities
At x = 10, the left-hand limit is ∞ and the right-hand limit is -∞. Both one-sided limits are infinite, so this is an infinite discontinuity.
At x= 1, both one-sided limits are equal, but g(1) does not exist,
At x= 4, the limits are equal, and g(4) = 3.
In each case, the holes can be removed by redefining g(x), so the holes are removable discontinuities.
The function f(x) is the total amount spent at a store, when purchasing x items that are $5 each and the items are not taxable.
What is the practical domain for the function f(x)?
A. all positive integers that are multiples of 5
B. all whole numbers
C. all positive integers
D. all real numbers
Answer:
B
Step-by-step explanation:
The domain is all possible values of x. Here, x is the number of $5 nontaxable items. So x must be an integer, and it can't be negative. It is possible for x to be 0. So x is all whole numbers.
The practical domain for the function f(x) which represents the total amount spent at a store is all whole numbers. Option B is correct.
What is domain of function?Domain of a function is the set of all the possible input values which are valid for that function.
The function f(x) represents the total amount spent at a store. The purchasing number of x items which are $5 each and the items which are not taxable is represented by x.
Thus, this function can be given as,
f(x)=5x
Now the domain of a function is the set of all the possible input values which are valid for that function. Thus, for this case the domain is,
-∞<x<∞
(-∞,∞)
For the practical domain, the numbers should be whole number to avoid negative amount value and integer amount.
Hence, the practical domain for the function f(x) which represents the total amount spent at a store is all whole numbers. Option B is correct.

The equation (x + 6)^2 + (y + 4)^2 = 36 models the position and range of the source of a radio signal. Describe the position of the source and the range of the signals
Answer:
position: (-6, -4)
range: 6
Step-by-step explanation:
The equation is that of a circle centered at (-6, -4) with a radius of √36 = 6. We presume that the "position" is that of the circle's center, and the "range" is the radius of the circle.
___
The standard form equation of a circle with center (h, k) and radius r is ...
(x -h)^2 +(y -k)^2 = r^2
Matching parts of the equation, we find ...
h = -6, k = -4, r = √36 = 6.
The source of the radio signal is at the point (-6, -4), and the range of the signals is within a circular area with a radius of 6 units.
The equation given, (x + 6)² + (y + 4)² = 36, is a mathematical representation of a circle in a Cartesian plane. This equation indicates that the source of the radio signal is at the center of the circle, which is the point (-6, -4).
The number 36 on the right side of the equation is the square of the radius of the circle, which implies that the radius of the circle is 6 units. Hence, the range of the signals emitted from the source is limited to a circular area with a radius of 6 units around the point (-6, -4).

Jivesh also has a more powerful Model B rocket. For this rocket, he uses the equation h=-490t^2+1260t. When is the height of the Model B rocket 810 centimeters? ( it also includes number 19, but I need 20)
Answer:
1.29 s
Step-by-step explanation:
h = -490t² + 1260t
810 = -490t² + 1260t
490t² - 1260t + 810 = 0
49t² - 126t + 81 = 0
(7t - 9)² = 0
7t - 9 = 0
t = 9/7
t ≈ 1.29
To find the time when the rocket is at a height of 810 cm, set the equation -490t^2 + 1260t equal to 810 and solve for t using the quadratic formula. The quadratic formula will give two solutions: choose the positive solution as we cannot have negative time.
Explanation:We are given the equation h=-490t^2+1260t to represent the height of the rocket. We're also told that the height h is 810 cm and we are asked to solve for time t when this is the case.
To find the time when the rocket's height is 810 cm, we can first set the equation equal to 810: -490t^2 + 1260t = 810.
We can then simplify that to -490t^2 + 1260t - 810 = 0 and solve for t using the quadratic formula t = [-b ± sqrt(b² - 4ac)] / 2a, where a = -490, b = 1260 and c = -810.
This will give us the two points in time at which the rocket is at a height of 810 cm. Remember, the negative solution is likely extraneous as we cannot have negative time, so you should consider only the positive solution.

I have a vase that is shaped like a rectangular prism. The height is 10 inches. The length of the base is 6 inches. The width of the base is 5 inches. What is 2/3 of the volume of the vase? If necessary, round to the nearest whole number.
Answer:
[tex]200in^3[/tex]
Step-by-step explanation:
To solve this, we are using the formula for the volume of a rectangular prism:
[tex]V=whl[/tex]
where
[tex]w[/tex] is the width of the base
[tex]l[/tex] is the length of the base
[tex]h[/tex] is the height of the prism
We know from our problem that the height is 10 inches. The length of the base is 6 inches. The width of the base is 5 inches.
Replacing values
[tex]V=(5in)(10in)(6in)[/tex]
[tex]V=300in^3[/tex]
Now, to find 2/3 of that volume, we just need to multiply it by 2/3
[tex]\frac{2}{3} V=\frac{2}{3} 300in^3[/tex]
[tex]\frac{2}{3} V=200in^3[/tex]
We can conclude that 2/3 of the volume of the vase is 200 cubic inches.

Answer:
y ≈ - 3.8
Step-by-step explanation:
Given the 2 equations
5x + 2y = 21 → (1)
- 2x + 6y = - 34 → (2)
To eliminate the terms in x , multiply (1) by 2 and (2) by 5
10x + 4y = 42 → (3)
- 10x + 30y = - 170 → (4)
Add (3) and (4) term by term
(10x - 10x) + (4y + 30y) = (42 - 170)
34y = - 128 ( divide both sides by 34 )
y ≈ - 3.8 ( to the nearest tenth )
A car will be traveling a total distance of 520 miles. The first part of the trip takes 2 hours, and the car’s average rate is 65 miles per hour. If the entire trip takes 8 hours, what is the car’s average rate, in miles per hour, during the second part of the trip?
49
57
50
65
Final answer:
The car's average rate during the second part of the trip is 65 miles per hour, which is calculated by dividing the remaining distance of 390 miles by the remaining travel time of 6 hours.
Explanation:
We need to find the average rate of the car during the second part of the trip. We know the total distance of the trip is 520 miles and the total time for the trip is 8 hours. Since the first part of the trip was at 65 miles per hour for 2 hours, the car would have covered 130 miles (65 miles/hour * 2 hours).
We subtract the distance covered in the first part of the trip from the total distance to find the distance covered during the second part of the trip: 520 miles - 130 miles = 390 miles. The remaining time for the second part of the trip is 8 hours - 2 hours = 6 hours.
To find the average speed during the second part of the trip, we divide the remaining distance by the remaining time:
Average rate = Distance / Time = 390 miles / 6 hours = 65 miles per hour.

Juan drew a right triangle with leg lengths of 6 centimeters and 8 centimeters. He wants to draw another right triangle that is similar to the first one. Which could be the lengths of the legs?
The lengths of the legs of a similar triangle to the one Juan drew, which has leg lengths 6cm and 8cm, could be 12 cm and 16 cm because the sides of similar triangles are proportional.
Explanation:Juan's right triangle has leg lengths of 6 centimeters and 8 centimeters. To find a similar right triangle, we need ratios of corresponding sides to be equivalent or proportional. As these are right triangles, we can use the Pythagorean theorem which states that a² + b² = c². If the original triangle has sides 6 cm and 8 cm, then triangle with proportional sides could have sides that are multiple of these dimensions, such as 12 cm (which is 6cm x 2) and 16 cm (which is 8cm x 2). So, one example of a similar triangle could have leg lengths of 12 cm and 16 cm.

Two search teams spot a stranded climber on a mountain. The first search team is 0.5 miles from the second search team. If the angle of elevation from the first search team to the stranded climber is 15° and the angle of elevation from the second search team is 22° to the stranded climber, what is the altitude of the climber if both search teams are standing at an altitude of 1 mile high?
Answer:
The altitude of the climber is 1.40 miles
Step-by-step explanation:
see the attached figure to better understand the problem
we know that
In the right triangle BCD
tan(22°)=h/(x-0.5)
h=tan(22°)*(x-0.5) ----> equation A
In the right triangle ACD
tan(15°)=h/x
h=tan(15°)*(x) ----> equation B
Equate equation A and equation B and solve for x
tan(22°)*(x-0.5)=tan(15°)*(x)
tan(22°)*x-tan(22°)*0.5=tan(15°)*x
x[tan(22°)-tan(15°)]=tan(22°)*0.5
x=tan(22°)*0.5/[tan(22°)-tan(15°)]
x=1.48 miles
Find the value oh h
h=tan(15°)*(1.48)=0.40 miles

This isn't an explanation of the math but more of a visualization for those that just needed the 2D representation. The real answer would be 1.081 miles (:
A spinner has five equal sections that are numbered 1 through 5.
In which distributions does the variable X have a binomial distribution?
Select EACH correct answer.
When the spinner is spun three times, X is the sum of the numbers the spinner lands on.
When the spinner is spun multiple times, X is the number of spins until it lands on 5.
When the spinner is spun four times, X is the number of times the spinner does not land on an odd number.
When the spinner is spun five times, X is the number of times the spinner lands on 1.
Answer:
Step-by-step explanation:
X has a binomial distribution when the probability of X is the same for each spin.
When the spinner is spun four times, X is the number of times the spinner does not land on an odd number.
When the spinner is spun five times, X is the number of times the spinner lands on 1.
Answer with explanation:
Total number of sections in the spinner = 1 to 5=5 in all
For, a Distribution to be a Binomial Distribution,
Number of trials should be fixed.
All trials should be Independent of one another.
Only two outcomes are Possible one is called Success and Other is failure.
Probability of each Outcome should remain constant irrespective of number of trials.
Probability of getting either of 1,2,3,4,or 5 when the spinner is spun once
[tex]=\frac{1}{5}[/tex]
Option C
When the spinner is spun four times, X is the number of times the spinner does not land on an odd number.
Probability of Failure ={1,3,5}=Getting odd number on spinner
[tex]=\frac{3}{5}[/tex]
Probability of Success={2,4}=Getting even number on spinner
[tex]=\frac{2}{5}[/tex]
Number of trials is fixed and each trial is independent of another.
Option D
Total Number of Trials= 5
Probability of Success = When the Spinner is spun and it Lands on 1
Probability of Failure = When the Spinner is spun and it does not Land on 1
When the Spinner is spun five times ,Probability of each Outcome,that is either of 1,2,3,4,or 5 is constant which is [tex]\frac{1}{5}[/tex]
⇒⇒When the spinner is spun five times, X is the number of times the spinner lands on 1.
