Answer:
415 books, I dont understand the second question, sorry
Step-by-step explanation:
1 small box=20 books
1 big box=45 books
5 small boxes×20 books= 100 books
7 large boxes×45 books= 315 books
315 books+100 books=415 books
Answer:
3w - 9/2 is the equivalent expression
This is a perfect example of exponential decay. In this case the growth factor should be represented by a fraction, and it is! This forest, starting out with apparently ( 800? ) pine trees, has a disease spreading, which kills 1 / 4th of each of the pine trees yearly. Therefore, the pine trees remaining should be 3 / 4.
Respectively 3 / 4 should be the growth factor, starting with 800 pine trees - the start value. This can be represented as such,
- where a = start value, b = growth factor, t = time ( <em>variable quantity</em> )
____
Thus, the function
can model this problem. The forest after t years should have P( t ) number of pine trees remaining.
Let us consider the distance between kensington and greenwich be x
since the given figure is a right angled triangle,we use pythagoras theorem to find the answer
so by pythagoras theorem
x^2= 20^2+40^2
x^2=400+1600
x^2=2000
x=root of 2000=20root 5mi
answer is option (b)
