Answer:

              \bold{2+\frac{5i}3-2i=2-\frac{1}3i}

or if you mean (2 + 5i)/(3 - 2i) at complex numbers

              \bold{\dfrac{2+5i}{3-2i}=\dfrac{-4+19i}{13}=-\frac{4}{13}+1\frac{6}{13}\,i}.

Step-by-step explanation:

\bold{2+\frac{5i}3-2i=2+\frac{5i}3-\frac{6i}3=2-\frac{1}3i}

But I think you mean:  (2 + 5i)/(3 - 2i) and complex numbers.

Then:

\dfrac{2+5i}{3-2i}=\dfrac{(2+5i)(3+2i)}{(3-2i)(3+2i)}=\dfrac{6+4i+15i+10i^2}{9+6i-6i-4i^2}=\dfrac{6+19i-10}{9+4}=\dfrac{-4+19i}{13}

The average cost when producing x items is found by dividing the cost function, C(x), by the number of items, x. When is the ave
kakasveta [241]

Answer:

<em>The average cost is less than 100 when the number of items x is greater than 2</em>

Step-by-step explanation:

The cost equation is C(x) = 10x + 180

The average cost Cp = \frac{C(x)}{x}

We want to know when the cost Cp is less than 100.

So

Cp

Cp = \frac{C(x)}{x}

10 + \frac{180}{x}

For x> 0

\frac{180}{90}

x> 2

The average cost is less than 100 when x>2

Tennis racket marked up 50% to $36.76
Kaylis [27]
I asssume we want to find the original price
so marked up 50% means if original price=100, then marked up price=50+100=150%

so
36.76=150%
hack, since 150=3 times 50 and 2 times 50=100, divide 36.76 by 3 then mutiply by 2

36.76=150%
divide both sides by 3
12.25333333333=50%
multiply both sides by 2
24.5=100%
original price=$24.50
