The height h, in feet, of an object t seconds after it is dropped from a height of s feet can be modeled by the function h(t)=−16t2+s . From a branch of an oak tree 64 feet above the ground, a squirrel dropped an acorn. The acorn fell straight to the ground without hitting any branches on the way down. According to the model, approximately how long did it take the acorn to hit the ground? A: 1 second
B: 2 seconds
C: 4 seconds
D:8 seconds

answer: (1,3) and (-2,0) i think.

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

answer

false

explanation

these practices describe the manner the land use outcome is attained. land management methods implemented by corporations are a mandatory because they are a driver for better land use results economically, socially and environmentally. corporations are required to understand the connection between land use , and land management practices to support sustainable land use policies
