The equation y = 109.62(1.023) models the population of a country from 1920 through 1990. In the equation, y is the population in millions and x represents the number of years after 1920
a. Estimate the population of the country in 1970
b. Assuming this equation continues to be valid in the future, use the equation to predict the population of the country in 2050
a.
million people (Round to the nearest tenth.)
b. million people (Round to the nearest tenth.)

explanation:

infrared radiation has wavelength in the range between 700 nm and 1 mm. lets' convert these values into scientific notation, keeping in mind that:

let's start from the lower value, we have:

(we moved the dot two places to the left, so we increased the exponent by 2 units, from -9 to -7)

the higher value is:

so, the range of wavelength of infrared radiation is:

answer: (-6,3)

step-by-step explanation:

hello, sorry being so rude after all that fighting i found it kind of funny, so as me saying sorry here is an answer!

since the table showed her that   2km = 2000m.

to determine, how many km in 2000m, she would divide by 1000.

= 2000 / 1000 = 2 km.

similarly, for 8000m = 8000 / 1000 = 8 km

cheers to savings
