1 stack of nickels is S=45gm; given that there are 9 nickels on each stack you can
divide the mass of the stack(
45)
by the
number of nickels in a stack(
9) to
find the
mass of 1 single
nickel
<u>5gm = 1 nickel</u>
Answer:
when the 9x moved to the other side he didnt change the sign
Step-by-step explanation:
-8x +32 = 9x-9
-9x - 8x + 32 = 9
Answer:
I hope this helps
Ex: vertical translation |x+5|-2 the graph will shift down 2 units. Or the same as (x+5)+2 in this case the graph will shift up 2 units.
Horizontal translation |x+5|-2 the graph will shift to the left 5 units. Or same as (x-5)-2 in this case the graph will shift over to the right 5 units.
Step-by-step explanation:
Vertical translation is when a graph is being shifted up or down.
Horizontal translation is when a graph is being shifted over left or right.
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.
Answer:
1st : neither linear nor nonlinear
2nd: nonlinear
3rd: linear
