Answer:

$\large\boxed{12\sqrt5}$

Step-by-step explanation:

$\text{Use}\ \sqrt{ab}=\sqrt{a}\cdot\sqrt{b}\\-----------------\\\\-4\sqrt{15}\cdot\left(-\sqrt3\right)=4\sqrt{(15)(3)}=4\sqrt{5\cdot3\cdot3}=4\sqrt5\cdot\sqrt9\\\\=4\sqrt5\cdot3=12\sqrt5$

The parabola x = y² - 9 opens: a.)up b.)down c.) right d.)left

Zolol [24]

Answer:

Right side towards positive x axis

Step-by-step explanation:

Let us see the basic rule to find the orientation of parabolas.

1. If power if x is 2 and y is 1 , the parabola opens up or down.

2. If the power of y is 2 and that of x is 1 , the parabola opens right or left.

3. If the coefficient of $x^{2}$ in case 1 is negative it opens downward

4. If the coefficient of $y^{2}$ in case 2 is negative , it opens left towards negative x axis.

Hence our equation is

$x=y^2-9$

here is satisfies the case 2. hence it opens right or left . Also the coefficient of

$y^{2}$ is positive so it opens up to the right side , that is towards positive x axis.

GenaCL600 [577]

Let x be the time required to do the job when they work together.
1/x = 1/9 + 1/10 = 19/90
x = 90/19 = 4.7 hours
