Using the given exponential function, it is found that it will take 1.5 years for the amount of savings to double from the initial amount deposited of $1250.
<h3>Exponential function:</h3>
The <em>exponential function</em> that models the savings in the bank account is given by:

- In which t is the time in years that the money has been in the account.
The time to double from the initial amount deposited of $1250 is t for which S(t) = 2(1250) = 2500, hence:








It will take 1.5 years for the amount of savings to double from the initial amount deposited of $1250.

Answer:
here's the steps
Step-by-step explanation:
first of the numbers inside the [ ] is always positive.Now since the 3 is outside the [ ] you use it like a tool and don't change it, so nothing happen to it.since ^3 is missing a base (variable, cannot remember exact name) but is not missing ^3, which make them alike enough to multiply because 3 is outside of () nut the ^3 will stay the same (don't know why but that's how math works)
Answer:
2000
Step-by-step explanation:
A(m) = 100 + 0.20m
B(m) = 80 + 0.3m
---------------------------
For company A to have a better deal, the truck must be driven more than __ miles per day.
Solve::
100 + 0.2m < 80 + 0.3m
-------
20 < 0.1m
m > 2000/1 = 2000 miles
---------------
2500 mi
Answer:
(x, y ) → (x + 5, y - 3 )
Step-by-step explanation:
5 units right means add 5 to the x- coordinate
3 units down means subtract 3 from the y- coordinate
the translation rule is
(x, y ) → (x + 5, y - 3 )
Answer:
(4, 1)
Step-by-step explanation:
x^2 + y^2 - 2y - 8x - 19 = 0
We rearrange the terms and complete the square twice.
x^2 - 8x + y^2 - 2y = 19
x^2 - 8x + 16 + y^2 - 2y + 1 = 19 + 16 + 1
(x - 4)^2 + (y - 1)^2 = 6^2
The center is (4, 1)
