Does a proportional relationship exist? Find the constant rate of change & interpret its meaning. A. Yes, Every 1 day, sales increase by $1000
B. Yes, Every 3 days, sales increase by $1000
C. No, Every 2 days, sales increase by $500
D No. Every 3 day, sales increase by $30

B. Yes, Every 3 days, sales increase by $1000

Step-by-step explanation:

A proportional relationship exists because the line cuts across the point of origin, (0, 0).

Constant rate of change is that there is an equal sales increase of $1,000 on every 3 days. Thus, on day 3, sales was $1,000. On day 6, sales was $2,000.

This shows proportional increase of $1,000 of sales, every 3 days.

so then what are you asking?

step-by-step explanation:

the largest number of the four options is 1.8 x 10-2

you have it in scientific notation.

1.80 x 10-6   = 0.00000180

1.80 x 10-4   = 0.000180 (bigger, or "less small", than the former one)

so

1.8 x 10-2       = 0.0180. as you see. the "less small", or the biggest one of them all.

as you have negative exponent, it means you are dividing 1.8 by 100 (i.e. moving the dot towards left, two times).

if you had positive exponent for the scientific notation, power of tenths, you would be multiplying times 100 (moving the dot towards right) as below:

1.8 x (10)2 = 180

so. if you have negative exponent in scientific notation, move the dot toward left. if it is positive, toward right as many times the exponent tells you.
