Answer:
115 bacteria
Step-by-step explanation:
The function that gives the number of bacteria in a science experiment is:
f(x) = 30(1.4)^x
Where x is the number of days
After 4 days (x = 4), the number of bacteria will be:
f(4) = 30 * (1.4)^4
f(4) = 39 * 3.8416
f(4) = 115.248 = 115 (To the nearest whole number)
The number of bacteria after 4 days is 115.
Answer:

Step-by-step explanation:
Pythagorean theorem

Earth to Neptune is the greatest distance. The number at the top is a power. So 22 to the power 4 is 22 x 22 x 22 x 22 = 234 256. 22 to the power 7 is 22 x 22 x 22 x 22 x 22 x 22 x 22 = 2 494 360 000. It is 22 to the power 3 larger which is 10 648 times greater.
