Given:
The exponential function is:
To find:
The percentage rate of increase or decrease.
Solution:
The general exponential function is:
...(i)
Where, a is the initial value, |r| is the growth rate in decimals if r>0 and |r| is the decay rate in decimal if r<0.
The exponential function is:
It can be written as:
...(ii)
On comparing (i) and (ii), we get
Since r is negative, therefore the given function is a decreasing or decay function.
Now,
So, the rate of decrease is 0.06. Multiply this number by 100 to get the percentage.
Therefore, the rate of decrease is 6%.
Step-by-step explanation:
2tan 30° / 1 + tan² 30° =
2(⅓√3) /1 + (⅓√3)² =
⅔√3 / 1+ ⅓ =
⅔√3 / 4/3 =
2/4 √3 =
½√3 = sin 60° (proven)
Answer:
Average rate of change in amount of the element over 10 minutes is 0.15 per minute.
Step-by-step explanation:
Given question is incomplete; find the attachment of this question attached with the answer.
In this experiment change in amount of the element has been plotted on y-axis and duration (time) on x-axis.
Change in amount of the element during 0 to 10 minutes = 1.5 units
Now the duration of this change in amount = 10 minutes
Therefore, rate of change in amount of the element =
= 0.15 units per minute
Answer:
x = ×-3/4
Step-by-step explanation:
because you hace the variable x and you do not know the number of fruit snacks he ate and you need to have the same variables to properly find the answer.
Answer:
36
Step-by-step explanation:
1/2-1/3=?
3/6-2/6=1/6
so lets try 36 since 6x6=36
1/2 of 36 is 18
1/3 of 36 is 12
18-12=6
