The center of an ice rink is located at (0, 0) on a coordinate system measured in feet. Sandi skates along a path that can be modeled by the equation y = 0. 08x2 - 1. 6x 13. David starts at (20, 13) and skates along a path that can be modeled by a quadratic function with a vertex at (10, 5). Which system of equations models the paths of the two skaters? y = 0. 08x2-1. 6x 13 and y = 0. 08(x-10)2 5 y = 0. 08x2-1. 6x 13 and y = 1. 6(x-10)2 5 y = 0. 08x2-1. 6x 13 and y = 0. 8(x-10)2 5 y = 0. 08x2-1. 6x 13 and y = 5(x-10)2 5.

I think that the answer is y = 0. 08x2-1. 6x 13 and y = 5(x-10)2 5, but i am not sure.

Step-by-step explanation:

inequality:

620-37.4p ≥ 450

the minimum amount of packages needed to be removed from the elevator is 5.

step-by-step explanation:

option 2 is correct.

step-by-step explanation:

we are given two inequality equation

x+y> 5 and -3x+2y< -2

first we draw the graph of both function using t-table method

equation: x+y> 5

for x=0, y=5

for x=-5, y=0

table:

x   :   0     5

y   :   5     0

test point (0,0) , 0> 5

false

equation: -3x+2y< -2

for x=0, y=-1

for x=2, y=4

table:

x   :   0     2

y   : -1       4

test point (0,0) , 0< -2

true

now we draw the graph. see the attachment for graph.

common region would be solution set.

option 2 is correct.
