For this case we have a function of the form:

Where,
A: it is the initial amount
b: is the growth rate
x: it's time
Substituting values we have:

For 20 days we have:
Answer:
the amount will be 2447839 pounds in 20 days
Answer:
A. 4.4652 square meters
B. $125.03
Step-by-step explanation:
A countertop is 16 feet long and 3 feet wide.
A. Calculation for What is the area of the countertop in square meters
First step is to calculate to convert 16 feet long length to meters and 3 feet wide length to meters
Since 1 meter=3.28 Feet
Hence,
Meters=16 feet long /3.28 Feet
Meters=4.88 meters
Meters=3 feet wide/3.28 Feet
Meters=0.915 Meters
Now let calculate the area of the countertop in square meters
Area of the countertop=4.88 meters*0.915 Meters
Area of the countertop=4.4652 square meters
B. Calculation for How much will it cost to cover the countertop with new tile
Total cost=$28*4.4652 square meters
Total cost=$125.03
Therefore How much will it cost to cover the countertop with new tile is $125.03
For the first point, remember this simple rule: every exponential function
always returns
when evaluated at
. In fact,
for every possible base
.
So, we can see that the graph of the exponential passes through the point
where
appears to be between 1 and 2. So, the only feasible option would be
, because it passes throught the point
because
.
The other functions are wrong because:
would pass through
, which would be between 0 and 1 on the y axis
would pass through
, which would be between 2 and 3 on the y axis
would pass through
, which would be between 0 and 1 on the y axis
As for the second question, you simply have to plug in the values: the function

means that you have to choose an input, x, and use it as exponent for 7. So, if you choose x=2, it means that you have to give exponent 2 to 7, i.e. you replace the x with the specific value, 2.
So, the expression becomes

Answer:
x=1, y=2
