Rewrite each equation into standard form. 7. y = (x + 3) (x - 4)

8. y = (x - 2)²

9. y = -3x(x + 5)

10. y = 2 (x - 1) (x - 2)

11. y = -2(x + 3)²

Even if you don't answer all of them, thank you very much!

Given the graph below state whether or not the relation is a function, and give the domain and range.

3x = 729 solve for x plz . it's urgent. will mark

Nthe opening scene of the movie raiders of the lost ark, indiana jones replaces a golden statue with a bag of sand. the platform on which the statue is placed is designed to detect the mass of the statue. if the bag of sand has a different mass than the statue, then a mechanism triggers and destruction ensues. the density of gold is about 20\text{ g/cm}^320 g/cm 3 20, space, g, slash, c, m, start superscript, 3, end superscript. the density of sand can be estimated at 2.5\text{ g/cm}^32.5 g/cm 3 2, point, 5, space, g, slash, c, m, start superscript, 3, end superscript. the gold statue can be modeled as a cylinder with height 25\text{ cm}25 cm25, space, c, m and radius 8\text{ cm}8 cm8, space, c, m. in terms of \piπpi, what is the mass of sand indiana jones needs to avoid triggering the mechanism?
