Parallelogram jklm is shown on the coordinate plane below:

if parallelogram jklm is rotated 270° clockwise around the origin, what are the coordinates of the endpoints of the side congruent to side kl in the image parallelogram?

choices are:

a- k'(−4, −6); l'(3, −3)
b- k'(−6, −4); l'(−3, −3)
c- k'(6, 4); l'(3, 3)
d- k'(−4, 6); l'(−3, −3)

step-by-step explanation: a reaction is first order. if the initial reactant concentration is 0.0200 m, and 25.0 days later the concentration is 6.25 x 10-4 m, then its half-life is:

12.5 feet

step-by-step explanation:

the answer is 11.2 (i know i’m late)

yes, gavin is right.

step-by-step explanation:

gavin is correct. 

this problem is about converting 9% per year to how many percent per quarter. the rate is still the same. it only differed in the time period. so, through dimensional analysis,

9% per year  × (1 year / 4 quarters) = 2.25% per quarter

if he was asked to convert 9% per year to how many percent per quarter  compounded quarterly, then you will not simply divide by four. this is because compounding is not linear.

hope this , have a good day. c;
