Quadrilateral pqrs has vertices p(-2,4) q(0,5) r(1,4) and s(-2,3). determine if quadrilateral pqrs is a rectangle

No, quadrilateral PQRS is not a rectangle. The opposite sides are not parallel

Step-by-step explanation:

we know that

A rectangle is a quadrilateral that has opposite sides parallel and congruent and its internal angles are right angles

we have

vertices P(-2,4) Q(0,5) R(1,4) and S(-2,3)

using a graphing tool

Plot the vertices to better understand the problem

Observing the figure , the opposite sides are not parallel

therefore

Is not a rectangle

step-by-step explanation:

the original amount doesn't ''re just looking for the time it takes for 1/2 of the substance to we have

(1/2) =)     take the ln   of both sides

ln (1/2)   = )   and we can write

ln(1/2) = ) lne     and lne   = 1     so we have

ln(1/2) = -.1092t     divide both sides by -.1092

t = ln(1/2)/-.1092 = about 6.347 days = about 6.3 days (rounded)

answer: all of the odd numbers were opened

the first person was the one that was opening all of the lockers. since one is odd, this causes all of the odd number lockers to be opened in the end.
