Answer:

The correct answer is inject cash into it.

Explanation:

Every day, central banks lend money to private banks through auctions. The extraordinary thing about these new liquidity injections starring the European Central Bank or the US Federal Reserve is not so much the operation itself, as the situation in which they occur.

In this case, problems arise when, due to distrust, banks do not lend money to each other, operations that are common when the system is working properly.

With extraordinary placements, the central entities replace that lack of funds that private banks have not been able to obtain from their partners and, at the same time, at a cheaper price - at a lower interest rate.

tatiyna

Answer:

28.85

Explanation

Keanu has decided to save a fixed amount of 70,000 for a given period. We would need to calculate the number of years to achieve 7,796,223 using the FVIFA formula (Future value interest for an annuity)

Fixed payment× FVIFA=Future value

<em>FVIFA</em> = \frac{(1+r)^{n} - 1}{r}

where r is the periodic rate (9%)

and n is the number of periods

therefore; 70000×\frac{(1+0.09)^{n} - 1}{0.09}=7796223

{(1+0.09)^{n} }=(7796223×0.09)/70000

n=27.85

However, since Keanu will not invest until the end of the first year, he will spend 28.85 years to achieve his goal
