The number of young adult hikers in a country has steadily increased since 2010 The equation y = 0 223 +285 can be used to estimate the number of young adults participating in hiking in the country, in mmillions, x years after 2010 a) Estimate the number of young adult hikers in the country in 2018
by in what year wit 48 million young adults participate in hiking in the country?
a) The number of young adult hikers in the country in 2018 is approximately 461 milion
(Round to two decimal places as needed)
b) There will be 48 million young adults participating in hiking in the year
(Round to the nearest year as needed)

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.
