If a bank has total deposits of $7,200 and reserves of $1,600: instructions: round to the nearest whole number. (a) what is its
Serjik [45]
A.) The current reserve ratio is given by the fraction of the bank's total deposits held in reserves.
Given that the bank's total deposits is $7,200 and the reserves is $1,600, the current reserve ratio is given by:

\frac{1,600}{7,200} \times100\%=22\%.


b.) The loan portfolio is given by (total deposit - reserves) / total deposits

Thus, the loan portfolio of the given bank is given by:

\frac{7,200-1,600}{7,200} \times100\%= \frac{5,600}{7,200} \times100\% \\  \\ =78\%

Let f(x) be a quartic polynomial with integer coefficients and four integer roots. Suppose the constant term of f(x) is 6.(a) Is
frez [133]

Answer:

  (a) yes

  (b) no; see below

Step-by-step explanation:

(a) Integer roots of the quartic will be integer divisors of 6. One of the divisors of 6 is 3, so 3 is a possible root.

(b) In order for 3 to be a double root, it would have to be a double factor of 6. The only integer factors of 6 are 1, 2, 3, 6. (3² = 9 is not one.)

___

The quartic can be written as ...

  k(x -a)(x -b)(x -c)(x -d) . . . . . where a, b, c, d, k are integers

The constant term will be kabcd, of which each of the roots is a factor. If the constant is 6 and one root is d=3, then we must have

  kabcd = 3kabc = 6

  kabc = 6/3 = 2

Among these four integer factors, there must be an even number of minus signs, and one that has the value ±2. Another root whose value is 3 will not satisfy the requirements.
