Step-by-step explanation:
-9x^3(x^2 - 4x - 21) =
-9x(x - 7)(x + 3) <===
The density of the gold sample is 19.3g/cm³
Let the mass of the gold sample be represented by m
m = 579 g
Let the volume of the gold sample be represented by V
V = 30 cm³
Let the density of the gold sample be represented by ρ
The formula for the density is:
![Density = \frac{Mass}{Volume}](https://tex.z-dn.net/?f=Density%20%3D%20%5Cfrac%7BMass%7D%7BVolume%7D)
![\rho = \frac{m}{V} \\\rho = \frac{579}{30} \\\rho = 19.3 g/cm^3](https://tex.z-dn.net/?f=%5Crho%20%3D%20%5Cfrac%7Bm%7D%7BV%7D%20%5C%5C%5Crho%20%3D%20%5Cfrac%7B579%7D%7B30%7D%20%5C%5C%5Crho%20%3D%2019.3%20g%2Fcm%5E3)
The density of the gold sample is 19.3g/cm³

If this is a proportion, then the answer is 16.
3:12, 4:16
3*16=12*4
The answer is Letter B - $4,280.00.
Total the amount they could incur because of health issues in a year then deduct it from 12,500.
= 685 x 12 months
= 8,220; they incur $8,220 for their health related issues in a year
= 12,500 - 8,220
= 4,280; amount they need to pay before the insurance company assumes responsibility.
The domain equals all of the x values which are represented on the left in a mapping diagram.
Order the values in order from L to G and put them within braces.
Final answer: x= {3, 6, 8}
