we are given the function adn we can see that when t is increased, P(t) is decreasing because of the negative sign. This means the value of the population which is the original of 64 billion will have to decrease.The answer that makes sense here is D. D. In 1990, there were 5.33 billion people.
It’s x=0 isn’t it that answer
-6.5(n-5)=18.2
Use Distributive Property:
-6.5n + 32.5 = 18.2
Subtract 32.5 from both sides:
-6.5n = -14.3
Divide both sides by -6.5
n = -14.3 / -6.5
n = 2.2
If you notice the terms, they're
7, -21, 63, -189 and so forth.
7*-3 = -21 and -21 * -3 is 63 and so forth, meaning the "common ratio" is -3.
now, for a common ratio say "r", which is a fraction, namely less than ±1 and more than 0, or |r| < 1 , you do have a convergent sequence.
however this one notice, |-3| is 3, and that's greater than 1 clearly, therefore is divergent, meaning the summation has no finite value.
The answer is 2/5 simplified to the max.
To show my work here.
<span>1. 2×<span><span>1/3</span><span></span></span>×<span><span>1/2</span><span></span></span>×<span><span>6/5
2. 2 x 1 x 1 x 6 over 3 x 2 x 5
3. simplify 12 over 3 x 2 x 5
4. simplify again 12/30
5. and once again simplify LOL 2/5 is the last answer.</span><span></span></span></span>
