Answer:
D. x = log8 24
Step-by-step explanation:
we have this function
8^x = 24
Now we have to understand how the logarithm works.
we use the logarithm to know how much we have to raise a number to reach a result that we already know.
these two equations represent the same
a ^ b = c
log a c = b
8^x = 24
8 = a
x = b
c = 24
log a c = b
log 8 24 = x
option d.
Answer:
F(x)=(x-3)(x+8)(x-11)=0
(x-3)=0, (x+8)=0, (x-11)=0
X=3
X=-8
X=11
Answer:
Option B
Step-by-step explanation:
Given that the required reserve ratio is 20 percent.
Since banks are conservative they choose not to loan all their excess reserves
i.e. only 20% of deposits is kept as reserve and 80% lent.
This 80% will again be deposited in a bank and 80% of 80 i.e.64% would be lent. Thus this will form a geometric progression infinitely as
deposits
with common ratio 0.8<1
Hence infinite sum = 
So deposit multiplier is B) equal to 5
