Answer:
$2400
$12,400
Step-by-step explanation:
Simple interest equation:
PV(1+it)
we have
10000(1+.06*4)
10000(1.24)
12400
Subtract the PV to get the interest earned
12400-10000= 2400
We just found that the total would be 12,400 and so part B is already solved
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.
