The given formula is f(x) = 20(1.2)^x
The formula is the starting amount multiplied by 1 + the percentage raised to the number of weeks.
A) the percent increase is 20% ( 1.2 in the formula is 1 +20% as a decimal)
B) the original amount is $20
C) for 2 weeks, replace x with 2 and solve:
20(1.2)^2
20(1.44) = $28.80
After 2 weeks the coupon is $28.80
D) To solve for the number of weeks (x) set the equation equal to $100:
100 = 20(1.2)^x
Divide both sides by 20:
5 = 1.2^x
Take the natural logarithm of both sides:
ln(5) = ln(1.2^x)
Use the logarithm rule to remove the exponent:
ln(5) = x ln(1.2)
Divide both sides by ln(1.2)
x = ln(5) / ln(1.2)
Divide:
X = 8.83
At 8.83 weeks the coupon would be $100, so after 9 weeks the coupon would be greater than $100
The answer is 9 weeks.

Answer:
Her score after the first two holes is 5 over par
Step-by-step explanation:
Calculating golf scores we have;
Maya's score on the first hole is one under par
Maya's score on the second hole is six over par
Therefore we have Maya's score after the first two holes is given as follows;
She took one less than her allotted shot for the first score and 6 more than her allotted shot for the second hole
Her gross score is 1 under par + 6 over par = 5 over par
Therefore, her score after the first two holes is 5 over par
You shouldn’t need radius but the area is 46
you make the thing hanging of a square and the other big shape a triangle then 2x3 is 6 and 8x10 decided by 2 is 40 and 40+6 is 46
Answer:
$43.55
Step-by-step explanation:
From the information given:
The fee paid by the patient = $80
The approved amount by Medicare = 54.44
The physician's actual fee which is the medicare payment check:
= 54.44 × 0.80
= $43.55
