Becuase 80 is the same as 8 but has an extra 0 at the end (which makes it 80) and same for 20 to 2. 8 + 2 = 10 (now add a zero at the end). The answer should be 100.
Answer:
The correct option is (B)
.
Step-by-step explanation:
The exponential decay function is as follows:

Here,
<em>y = </em>final value
<em>a</em> = initial value
<em>r</em> = decay rate
<em>t</em> = time taken
It is provided that:
<em>a = </em>150 mg
<em>r</em> = 9% = 0.09
Then the next hour the amount of caffeine in the body will be:

Then after two hours the amount of caffeine in the body will be:

Similarly after 10 hours the amount of caffeine in the body will be:

Then the inequality representing the range of the exponential function that models this situation is:

Thus, the correct option is (B).
Answer:
y-2=2(x+3)
Step-by-step explanation:
m=(y2-y1)/(x2-x1)
m=(12-2)/(2-(-3))
m=10/(2+3)
m=10/5
m=2
y-y1=m(x-x1)
y-2=2(x-(-3))
y-2=2(x+3)

Given:
Graph of function 1.
The equation of function 2 is
.
To find:
The function which has a greater rate of change.
Step-by-step explanation:
From the given graph it is clear that, the function 1 passes through two points (0,0) and (1,2). So, slope of function is




So, rate of change of function 1 is 2.
On comparing the equation
with
, where m is slope and b is y-intercept, we get

So, rate of change of function 2 is
.
Since,
, therefore, function 1 has a greater rate of change.
