A scientist collected a 1-liter sample of sea water and then examined
it to see how many viruses, bacteria, phytoplankton, and protozoa it
contained. The scientist found that there were 1 x 10 ° phytoplankton
and 2 x 10 viruses in the sample.

How many times greater was the number of viruses than the number
of phytoplankton that were found in the sea water sample? Estimate
by rounding to the nearest whole number.

d

step-by-step explanation:

by observation, we can see that the the graph is simply the graph of y = |x| that has been shifted 4 units downwards and 3 units to the left.

we can recognize in choice d :

y = | x + 3 |   - 4 (rewriting in general form)

y = | x - (- 3) |   - 4

the "-4 " term means   that the graph has been shifted by 4 units in the negative y direction

the "-3 " term means   that the graph has been shifted by 3 units in the negative x direction

this matches our observation of the graph described above.

answer: sine

step-by-step explanation:

answer:

at time x=0 we have 1000, at time x=1 we have 2000, at time x=2 we have 4000.  

so that's an initial value of 1000 and a ratio of 2,

y = 1000 (2^x)

hope this !
