At the beginning of an experiment, a scientist has 292 grams of radioactive goo. After 135 minutes, her sample has decayed to 36.5 grams.
What is the half-life of the goo in minutes?
Find a formula for G(t), the amount of goo remaining at time t. G(t)
How many grams of goo will remain after 17 minutes?

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.

i think the answer is d im not sure

3100
