Answer:
3
Step-by-step explanation:
f(x) = 2x^2 + 1
f(-1) means that wherever you see an x on the right hand side, you substitute -1.
f(-1) = 2(-1)^2 + 1 = 2 + 1 = 3
The ration is 10/7
Divide 55 and 35 by 5 to reduce the fraction of 55/35 and you get 10/7
It would be f(t)= 25^t+1
If you plugged in '2' as 't',
25^2+1= 15, 625 which uses the second day of the bacteria.
Answer: 68
Step-by-step explanation:
