Acellphone weighs about 2.8x10^n pounds. which value of n is most reasonable?
a.) -3
b.) -2
c.) 0
d.) 1

Approximate weight of cell phone is between 100 gm to 200 gm.

1 Pound = 0.45359237 Kilograms

           = 0.4545 kg

2.8 pound = 2.8 × 0.4545

               = 1.2727 Kg

It is given that weight of cell phone is pounds, means Kilograms.

Which is equal to, grams.

Because, 1 Kilogram = 1,000 gram

If, n=0

Weight of cell phone = 1272.7 grams=1.2727 Kg

when, n=1

Weight of cell phone = 12727 grams=12.727 Kg

n= -2,

Weight of cell phone = 12.727 grams

n=- 3

Weight of cell phone = 1.2727 grams

None, of the weights are appropriate weight of cell phone.Neither of four options provided here is true.

a function could be identified in 3 ways either on a chart,graph, or ordered pairs. first a function is that each point has its own. the rule is that there can be many x's to one y but there can not be 2 x's at different y's. so on a graph when you put a straight line through the y's there should be one dot only to be a function.

step-by-step explanation:

you can first factor out the n to get n(1+5). we know that 1+5 is 6, so we just have 6n.
