If the slope is 26.5° what is the rise per meter

Rise / run = tangent of the angle.

Tan(26.5) = 0.49858... , so the rise per meter is about 1/2 meter.

A pizza place offers 3 different cheeses and 8 different toppings. In how many ways can a pizza be made
with 1 cheese and 3 toppings?

Answers

The cheese can be any one out of 3 = 3 choices.  For each of those . . .
The first topping can be any one of 8.  For each of those . . .
The second topping can be any one of the remaining 7 . For each of those . . .
The third topping can be any one of the remaining 6 .

Total number of ways to assemble a pizza = (3 x 8 x 7 x 6) =  1,008 ways.

BUT . . .

You could choose the SAME 3 toppings in (3 x 2) = 6 different ways, and
nobody could tell the difference once they were selected.  All 6 different
ways would result in the same pizza.

So, out of the 1,008 total different ways there are of choosing ingredients,
there are only ( 1,008 / 6 ) = 168 different and distinct pizzas.
1\ cheese\ is\ choose\ from\ 3:\ \ \ {3 \choose 1} =3\nand\ 3\ toppings\ are\ choose\ from\ 8:\ \ \ {8 \choose 3} = (8!)/(3!\cdot(8-3)!)= (5!\cdot6\cdot7\cdot8)/(2\cdot3\cdot5!)=56 \n\na\ pizza\ can\ be\ made\ on\ \ 3 \cdot 56=168\ \ ways

2^a X 2^b X 2^c

2^a+b X 2^a-b

Answers

i) 2 ^(a)*2 ^(b)* 2^(c)          
We know that x^(a) * x^(b) = x^(a+b)
Therefore, 
2 ^(a)*2 ^(b)* 2^(c)2 ^(a+b+c)
ii) 2 ^(a+b) * 2 ^(a-b)= 2^((a+b+a-b))
= 2^(2a)

Which of the following occurs during the ecological succession of an ecosystem?A. An ecosystem reaches a final, unchanging stage.

B. Animals move out of the ecosystem until succession is complete.

C. Living organisms modify their environment a little at a time.

D. Parts of communities split off to form new communities.

Answers

The answer is c. Living organisms modify their environment a little at a time.




The purpose of succession is for an ecosystem to reach balance state right after it is formed or after it is disturbed by man or some disasters. It will increase biodiversity and help to prevent the desertification. Living organisms modify environment a little at a time. By modifying it, they make the environment more suitable for the new species to enter the community.



I think the correct answer from the choices listed above is option C. During an ecological succession of an ecosystem, what happens is that living organisms modify their environment a little at a time in order for them to survive. Hope this answers the question.
