the coordinates of the vertices of quadrilateral rstu are r(−4, 1), s(4, −1), t(3, −6), and u(−5, −4). which statement correctly describes whether quadrilateral rstu is a rectangle?

which statement correctly describes whether quadrilateral rstu is a rectangle?

quadrilateral rstu is not a rectangle because it has no right angles.

quadrilateral rstu is a rectangle because it has four right angles.

quadrilateral rstu is not a rectangle because it has only two right angles.

here you go!

sorry if it is late, but this if for others with the same question so give the person above brainlist:

Step-by-step explanation:

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)
