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
Answer:
5/21
Step-by-step explanation:
5/3 divide by 7
5/3 / 7/1
5/3 x 1/7
5/21
i think its this
Answer:
x= 1, x= 4, and x= -3
Step-by-step explanation:
Use the possible combinations of factors of the constant term of the polynomial to find a first root. Try 1, -1, 2, -2, 3, -3, etc.
Notice in particular that x = 1 is a root (makes f(1) = 0):

So we know that x=1 is a root, and therefore, the binomial (x-1) must divide the original polynomial exactly.
As we perform the division, we find that the remainder of it is zero (perfect division) and the quotient is: 
This is now a quadratic expression for which we can find its factor form:

From the factors we just found, we conclude that x intercepts (zeroes) of the original polynomial are those x-values for which each of the factors: (x-1), (x-4) and (x+3) give zero. That is, the values x= 1, x= 4, and x= -3. (these are the roots of the polynomial.
Mark these values on the number line as requested.
Answer:

Step-by-step explanation:
we have

where
Q -----> is the daily output
A -----> is the number of people
For Q=621
Find the value of A
substitute and solve for A

Subtract 600 both sides


squared both sides


Subtract 41 both sides

Rewrite
