cars lose value the farther they are driven. a random sample of 11 cars for sale was taken. all 11 cars were the same make and model. a line was fit to the data to model the relationship between how far each car had been driven and its selling price. which of these linear equations best describes the given model? choose one (option a) y=1/2x+40 (option b) y=-x+40 (option c) -1/4x+40. based on this equation, estimate the price of a car that had been driven 56 thousand kilometers.

answer:

answer:

the answer is 1,648

sa= 2 (lw +lh + wh)

sa = 2 (384 + 120 + 320)

sa = 2 (824)

sa = 1,648 sq. cmanswer:

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)

the most boring ever written

step-by-step explanation:

i am writing something. yes, i plan to make it the most boring thing ever written. i go to the store. a car is parked. many cars are parked or moving. some are blue. some are tan. they have windows. in the store, there are items for sale. these include such things as soap, detergent, magazines, and lettuce. you can enhance your life with these products. soap can be used for bathing, be it in a bathtub or in a shower. apply the soap to your body and rinse. detergent is used to wash clothes. place your dirty clothes into a washing machine and add some detergent as directed on the box. select the appropriate settings on your washing machine and you should be ready to begin. magazines are stapled reading material made with glossy paper, and they cover a wide variety of topics, ranging from news and politics to business and stock market information. some magazines are concerned with more recreational topics, like sports card collecting or different kinds of hairstyles. lettuce is a vegetable.
