Answer:
Step-by-step explanation:
The formula to calculate the exponential growth function is equal to
where
f(x) is the population
P is the population in the year 2000
r is the rate in decimal
x is number of years since 2000
e is the mathematical constant number
we have
substitute in the formula above
Answer:
Since we know that each of the three triplets are the same age we can put next to n, 3.
And given that another child is 14 years old we can put that next to the "+" sign.
In total, it would equal 32, so put the 32 after the equal sign.
It should look like this:
3n + 14 = 32
But now they want us to solve for the triplet's ages, so we just solve for n;
3n + 14 = 32
-14 -14
3n = 18
/3 /3
n = 6, the triplet's ages are 6 years old each.
Answer:
10
Step-by-step explanation:
C = 0.75 + L
For L = 3 ; Cost, C = 3.75
3.75 = 0.75 + 3L
3.75 - 0.75 = 3L
3 = 3L
L = 3/3
L = $1
C = 0.75 + 1L
If amount spent is $10.75; C = 10.75
10.75 = 0.75 + L
10.75 - 0.75 = L
10 = L
Number of letters = 10
From the table, we can observe that the formula for the total cost of item is

From the data in the table, cost of item 6.00 has the input incorrect because the sum of the cost of its item and tax on the item is,

but the total cost was incorrectly inputed as 7.56.
Hence, the correct option is Option A.
