The zeroes are
0, -5, 3 + i (and its conjugate)

The factors are
x (x + 5) (x - (3 + i)) (x - (3 - i))
Expanding...
(x² + 5x)((x - 3) - i) ((x - 3) + i)
(x² + 5x)((x - 3)² - i²)
(x² + 5x)(x² - 6x + 9 - (-1))
(x² + 5x)(x² - 6x + 10)
x⁴ - 6x³ + 10x² + 5x³ - 30x² + 50x
x⁴ - x³ - 20x² + 50x

Answer:

$f=\frac{9c}{5}+32$

Step-by-step explanation:

$c=\frac{5\left(f-32\right)}{9}$

Switch sides:

$\frac{5\left(f-32\right)}{9}=c$

Multiply both sides by 9:

$\frac{9\times5\left(f-32\right)}{9}=9c$

$5\left(f-32\right)=9c$

Divide both sides by 5:

$\frac{5\left(f-32\right)}{5}=\frac{9c}{5}$

$f-32=\frac{9c}{5}$

Add 32 to both sides:

$f-32+32=\frac{9c}{5}+32$

$f=\frac{9c}{5}+32$

A paintball court charges an initial entrance fee plus a fixed price per ball.

m_a_m_a [10]

Answer : The cost of 10 balls will be, 13.5 dollars

Step-by-step explanation :

As we are given the following expression:

$P=0.80\times n+5.50$

where,

P = total price (in dollars)

n = number of balls used

Given:

n = number of balls used = 10

Now we have to determine the cost of 10 balls.

$P=0.80\times n+5.50$

$P=0.80\times (10)+5.50$

$P=8+5.50$

$P=13.5\$$

Thus, the cost of 10 balls will be, 13.5 dollars
