This is not a true statement
Answer:
y = 3(2^x)
Step-by-step explanation:
Put the given point values in the equation and solve for 'a' and 'b'.
3 = a(b^0) = a . . . . . for x=0, y=3
The y-intercept has given us the value of 'a'.
__
The other point will tell us 'b'.
48 = a(b^4) = 3(b^4) . . . . . for x=4, y=48
16 = b^4 . . . . . . . . . . . . . . . divide by 3
2^4 = b^4 ⇒ b = 2
The exponential function is ...
y = 3(2^x)
_____
<em>Additional comment</em>
We can use roots to find b:
16^(1/4) = (b^4)^(1/4) = b
2 = b . . . . your calculator can do this, or √(√16) = 16^(1/4) = 2.

Answer:
8
Step-by-step explanation:
3x = 24
Divide both sides by 3
3x/3 = 24/3
x = 8
Katelyn's balloon payment will be $127, 619.33.
We have PV (present value) of $368, 375 to be paid in 240 months (20 years, indicated by 20/6) with a mortgage at 4.65% (Annual Interest rate) to be converted into monthly interest rate (4.65/12= 0.3875%).
Using the formula:
P(Balloon) = (PV)(1+r)^n - P[((1+r)^n-1)/r)]
Balloon payment is the amount that has a term that is shorter than its amortization.
