Please help me out and explain it to me​

Mathematics
1 answer:
a_sh-v [17]3 years ago
8 0

Answer: C

Step-by-step explanation:

You can solve this by first multiplying both sides of the fraction by the conjugate of the denominator.

In this case, the conjugate is (8 - 2i).

So:

\frac{3-5i}{8+2i} *\frac{8-2i}{8-2i}

Simplify:

\frac{24-46i+10i^2}{64 - 4i^2}

Simplify again, knowing that i^2 = -1

\frac{14 -46i}{68}

Then, divide both numbers in the numerator by 68 to get your answer.

\frac{7}{34} -\frac{23i}{34}

A sum of money is deposited in a bank which offers a simple interest rate of 0.325% per annum. At
nikitadnepr [17]

Answer:

The sum of money deposited is approximately $22,021.74

Step-by-step explanation:

The given interest and amounts of the deposit are outlined as follows;

The simple interest per annum, R = 0.325%

The number of years the money is deposited, T = 4 years

The total amount received (Interest + Initial deposit), A = $50,650

We have;

I = P × R × T

Where;

P = The principal (initial amount deposited)

R = The (annual) interest rate = 0.325%

T = The time = 4 years

Therefore;

The total amount received, A = P + I

P + I = P + P × R × T = P × (1 + R × T)

∴ A = P + I = P × (1 + R × T)

P = A/(1 + R × T)

Plugging in the values, gives;

P = 50,650/(1 + 0.325 × 4) = 506,500/23 ≈ 22,021.74

The sum of money deposited, P = $22,021.74
