HELP!!! A lake currently has a depth of 30 meters. As sediment builds up in the lake, its depth decreases by 2% per year. This situation represents [exponential growth or exponential decay]
The rate of growth or decay, r, is equal to [.98 or .02 or 1.02]

So the depth of the lake each year is [1.02 or .98 or .02]
times the depth in the previous year.

It will take between [11 and 12 or 9 and 10 or 3 and 4 or 5 and 6]
years for the depth of the lake to reach 26.7 meters.

answer:   b

step-by-step explanation:

x2 = 16

x can not be a negative number because 16 is positive

the only answer would be positive 8  

step-by-step explanation:

consider an orange peel: if you want to try and lay it flat, you have to stretch it, we know exactly how things are being stretched or squashed at any given point. we have many different map projections because each has different patterns of some projections can even preserve certain features of the earth without
