(b)
(c)
Step-by-step explanation:
Formula of compound interest:
Compound continuously
A= Amount after t years
P= Principal
r= rate of interest
a)
P=10,000, r=5.5%= 0.055 and t= 5 years, n=2 [ compounded semiannually]
(b)
P=10,000, r=5.5%= 0.055 and t= 5 years, n=12 [ compounded monthly]
(C)
P=10,000, r=5.5%= 0.055 and t= 5 years
The number of blue balls that are needed to balance four green, two yellow and two white balls is 16 blue balls.
<h3>Numbers of blue balls needed</h3>
Green(g)
Blue (b)
Yellow (y)
White (w)
First step is to formula an equation
3g=6b
g=2b
2y=5b
y=5/2b
4w=6b
w=3/2b
Second step is to substitute
4g+2y+2w
=4(2b)+2(5/2b)+2(3/2b)
=8b+5b+3b
=16b
Therefore 16 blue balls are needed.
