The sphere at the top of a water tower holds enough water to pressurize the water supply for the city. The radius of the sphere measures 19 yards. Throughout the day, the water tower lost 7,234.56 cubic yards of water. If the water tower was completely full at the beginning of the day, about how much water is left in the water tower at the end of the day? (Use 3.14 for .)
Volume of a Sphere: 4/3πr^3
A.28,716 cubic yards
B.7,235 cubic yards
C.2,726 cubic yards
D.21,481 cubic yards

y = - 6

step-by-step explanation:

given the point (- 2, y) lies on the graph then it is a solution of it's equation.

substitute x = - 2 into the equation for value of y

y = 3(- 2) = 3 × - 2 = - 6

the point on the graph is (- 2, 6)

astronomers is your final answer! : )

the system of inequity is

step-by-step explanation:

from the given graph it is noticed that we have two related lines. one is solid and another is dashed.

if a line passing through two points, then the equation of line is

the solid line passing through the points (0,4) and (4,0).

the related equation of solid line is .

similarly, find the related equation of dashed line. the dashed liune passing through the points (0,0) and (3,1).

the related equation of dashed line is

from the given graph it is noticed that the point (0,1) lies on the shaded region, therefore the point (0,1) must be satisfied by the related equations.

check the related equations by the point (0,1).

this statement is true if the sign of inequality is < instead of equality. since it is an solid line therefore the sign of inequality will be . the required inequality is

similarly, check the second related equation.

it is a dashed line, so this statement is true if the sign of inequality is > . the required inequality is
