Answer:

$f(n)=-0.10n^2+8n+200$

Step-by-step explanation:

Let n represent number of new members and f(n) represent membership money.

We have been given that there are currently 20 members in the school's Ski Club. So when n new members join, the total number of members would be $20+n$ .

Since for each new member recruited the dues for all members will be reduced by 10 cents, so new dues would be $10-0.10n$ .

The membership money would be number of total members times dues as:

$f(n)=(20+n)(10-0.10n)$

Since we need our equation in standard form, so we will use FOIL to expand our equation as:

$f(n)=20(10)-20(0.10n)+n(10)-n(0.10n)$

$f(n)=200-2n+10n-0.10n^2$

$f(n)=200+8n-0.10n^2$

$f(n)=-0.10n^2+8n+200$

Therefore, our required equation would be $f(n)=-0.10n^2+8n+200$ .

Please help me out and explain it to me

a_sh-v [17]

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.

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