Answer:
P(t) = 200·0.95^t
Step-by-step explanation:
Each year, the population drops to 95% of its previous value. That is, the population is multiplied by 0.95 each year. Repeated multiplication is signified by an exponent. Here, that exponent is the number of years from today (t).
The population function can be written as ...
P(t) = 200·0.95^t
(121.54) x (91-6) =121.54 x 85 =10,330.9
or if these are exponents
(1.18 x 1000) x (9.1 x 0.000001)
(1,180) x (0.0000091)
0.010738
You would convert the percent into a decimal, which would be 0.00039296, then multiply it by 9, which is 0.00354564. To find the total, you would do 9 plus that, which is 9.00354564.
Answer:
All of these are the same. I would say D as theya re the same.
Answer:
Step-by-step explanation:
y-0.8x=0.5
y*10-0.8x*10=0.5*10
10y-8x=5
10y-8x+8x=5+8x
10y/10=5/10+8x/10
y=5+8x/10
5*5+8x/10-2.5
8x+5/2-2.5=4x
y=5+8x/10, x=x
