-5.50
Step-by-step explanation:
it’s -5.5. You just subtract -0.25 on the side where it’s negative and add 0.25 for the side that’s positive.
Answer:
24.1 billion
Step-by-step explanation:
One way to write the logistic function is ...
P(t) = AB/(A +(B-A)e^(-kt))
where A is initial value (P(0)), and B is the carrying capacity (P(∞)). We are told to use relative population growth in the 1990s as the value for k.
In billions, we have ...
A = 5.3
B = 100
k = 0.02/5.3 ≈ 0.003774 . . . . . relative growth rate at 20 M per year
t = 2450 -1990 = 460

Answer:
Step-by-step explanation:
Answer: <em>D) </em><u><em>He cannot construct a triangle</em></u>
Step-by-step explanation:
For a triangle to be possible <u>the largest side must be less than the sum of other two sides .</u>
In the given question largest side is 23 while other two sides are 8 and 14
Therefore for triangle to be possible 23 should be less than (8+14) but 23 > (8+14) .
Thus he can not construct a triangle using the given sides.
Hence correct option is <u><em>D)He cannot construct a triangle.</em></u>
Answer:
given
n=9
a=1
d=3-1=2
Step-by-step explanation:
now , by formula,
sn = n/2(2a+(n-1)d)
= 9/2(2×1+(9-1)×2)
=9/2×18
=81
