If there is a 5% drop every month, then the class becomes 1-5%=1-0.05=0.95 times the previous size.
The formula for

months would be

so for 12 months it would be
Answer:
C
Step-by-step explanation:
The volume (V) of a cone is calculated as
V =
area of base × height
=
× πr² × height
Here diameter = 22, thus r = 11 and h = 22
V =
× π × 11² × 22
=
× π × 121 × 22
= 
≈ 2787.64 → C
Answer:

Step-by-step explanation:
The equation of a line in slope-intercept form is.
----->(eq 1)
∴ m is slope

subtract x from both sides.


divide - 2 on both sides


----->(eq 2)
By comparing (eq 1) and (eq 2)


Answer:
$20,086.35
Step-by-step explanation:
To calculate the maturity value by compound interest, we will use the formula

where,
A = Maturity amount
P = Principal amount = $10,000
r = rate of interest = 4.65% = 0.0465
n = number of compounding periods = 365
t = time in years = 15 years
Now substituting the values,

= 

= 10,000(2.008635)
= 20086.353758 ≈ $20,086.35
The final value of your investment would be $20,086.35.
