Answer:
40.4%
Step-by-step explanation:
Given data
Initial depth= 5feet
Final depth= 5-3.2+6.6= 8.4feet
Hence the percent change
% change= FInal-initial/final*100
% change= 8.4-5/8.4*100
% change= 3.4/8.4*100
% change= 0.404*100
% change=40.4%
Hence the percent change is 40.4%
It would be H. hope this helps
Answer:
x^3=6
Step-by-step explanation:
x(x+2)+6(x+2)=60
x^2+2x +6x +12=60
Total = Principal * ((1 + rate/n)^(n*years)
Total = 3,000 * (1.04)^20
Total =
3,000 *<span>

<span>
6,573.37</span></span></span>
So, he will have to add (7,000 - <span>6,573.37) =
$ 426.63
answer is b

<h3>Part 1:</h3>
So firstly, remember that the <em>a variable is the initial value.</em> Since we start off with 6.08 billion, <u>6.08 billion is the a variable.</u>
Next, since this is a <em>growth by 1.26%</em>, add 1 and 0.0126 (1.26% in decimal form) together to get 1.0126. <u>1.0126 is the b variable.</u>
Putting it together, <u>the function is
</u>
<h3>Part 2:</h3>
Since 2020 is 20 years from 2000, plug in 20 into the t variable of the prior function to solve:

In context, <u>in 2020 the population will be 7.81 billion.</u>
