Write the standard equation for the circle with center (–2, 5) that passes through (1, 9).

a. (x – 2)2 + (y + 5)2 = 5
b. (x + 2)2 + (y – 5)2 = 5
c. (x – 2)2 + (y + 5)2 = 25
d. (x + 2)2 + (y – 5)2 = 25

Given f(x)= 9x+1 and g(x)=x^3, choose the expression (f*g)(x)

This graph shows which inequality? a ≤ –3 a > –3 a ≥ –3 a < –3

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?
