Answer:
Exponential Decay
Step-by-step explanation:
Because 7/8 is less than 1, it is exponential decay
We need to round the number to the nearest hundred throusands.
this means that we will check the number after the poaition of the hundred thousands, if it is 5 or more,then we will add one otherwise we will ignore it and add zeros.
based on this, the number in the position next to the hundred thousands is 8 which mean that we will add one to the hundred thousands positions while all others will become zero.
Therefore,
789,091 to the nearest hundred thousands is 800,000
40+25+25+70=160 Hope this helps! :)
