Answer:
This does represent an exponential function , because his savings increase by a constant rate
Step-by-step explanation:
Let
x -----> the number of weeks
y ----> the amount saved
In this problem we have a exponential function of the form
where
a is the initial value
b is the base
r is the rate of change
where
---- because he doubles the amount each week
---->
substitute
therefore
This does represent an exponential function , because his savings increase by a constant rate
The quotient is 212.96.
Solution:
Given expression is .
Divide the given expression to find the quotient.
Decimal rule when numerator is divided by 10, 100, 1000, 10000 etc..
- If you have one zero in the divisor (10), then the decimal point will move 1 place to the left of the last digit.
- If you have two zeros in the divisor (100), then the decimal point will move 2 place to the left of the last digit.
- If you have three zeros in the divisor (1000), then the decimal point will move 3 place to the left of the last digit.
Here, we have 3 zeros in the denominator.
So, the decimal point is move 3 digit to the left of the last digit.
So, option C is the right answer.
Hence the quotient is 212.96.
