<span>basically you write an exponential function for y=ab^x for a graph that includes (1,15) and (0,6)
then using (0,6) you get: 6 = ab^0
and using (1,15) you get 15 = ab^1
Equations:
a = 6
ab = 15
So, b = 15/6 = 5/2
Equation:
y = 6(5/2)^x</span>

As only the length of the room changed. It means the length of the room is increased by 175%, because of which the area is increased by 175%.
Therefore, the expression become


also


so, the area of Megan's room is increased by 0.75 square meters.
After he withdraws $50.00 in cash the bank reconciliation shows that Ryan would have: $1 501.98 in bank balance.
<h3>What is the solution to the above?</h3>
Add all the deposits
- 28 x 10 = 280
- 9 x 5 = 45
- 20 x 0.25 = 5
- 85 x 0.10 = 8.5
- 32 x 0.01 = 0.32
Total = $338.82
Add the checks
654.24 + 100.00 + 458.92
= $1,213.16
Total amount deposited is: Cash + Check
1,213.16 + 338.82
Total Deposit = $1,551.98
Less withdrawal of $50
$1,551.98 - $50
Balance left = 1 501.98
