I think you forgot to give the options along with the question. I am answering this question based on my research and knowledge. The condition that must have existed during the second four-month period can be described as depression. I hope that this is the answer that has actually come to your great help.
Answer:
16.25;
g(f(x)) ;
76 ;
f(g(x))
Explanation:
For 15 off
f(x) = x - 15
For 35% off
g(x) = (1 - 0.35)x = 0.65x
g(x) = 0.65x
A.)
For the $15 off coupon :
f(x) = x - 15
f(x) 40 - 15 = 25
For the 35% coupon :
g(x) = (1-0.35)x
g(x) = 0.65(25)
g(x) = 16.25
B.)
Applying $15 off first, then 35%
Here, g is a function of f(x)
g(f(x))
Here g(x) takes in the result of f(x) ;
For the $140 off coupon :
f(x) = x - 15
f(140) = 140 - 15 = 125
For the 35% coupon :
g(125) = (1-0.35)x
g(124) = 0.65(125) = $81.25
C.)
x = 140
g(x) = 0.65x
g(140) = 0.65(140)
g(140) = 91
f(x) = x - 15
f(91) = 91 - 15
f(91) = 76
D.)
Here, F is a function of g(x)
f(g(x))
f(x) = (0.65*140) - 15
Answer:
The interest rate for this bond is 8% per annum.
Explanation:
Given that,
a bond that costs $1,000 and pays an $80 interest each year.
To find the rate of interest, we use the following formula is
I=Prt
Here P = principal= $1,000
I=interest= $80
t=time= 1 year
∴80 = 1000×r×1
⇒r = 0.080
⇒r= 8%
The yield for this bond is 8% per annum.
