Consider a permutation of the first n positive integers. for example, if n = 10, then a possible permutation is p = [5,2,1,8,4,7,10,9,3,6]. consider a street that is 10 blocks long, where there is a building of height p[i] on the ith block. for example, there is a building of height 5 on the first block, a building of height 2 on the second block, a building of height 1 on the third block, and so on. if you are standing at the very left end of the street, you will be able to see some of these 10 buildings, but unfortunately many of them will be blocked by a taller building.

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

c: y > - 1/6x + 1

step-by-step explanation:

dashed line - meaning this < or > also not equal

solid line - meaning this < or > also equal

your answer is c because y > means up & it's shaded up, but y < means down

hope this ! : )

answer:

c) the x-coordinate of the center of the circle increases by 3

60: 45 =12: 9 =4: 3 so the answer is 4: 3
