The significance of 160,000 in the function is the initial population at the time of the estimation.
The correct option is (C)
<h3>What is data?</h3>
A collection of facts, such as numbers, words, measurements, observations or even just descriptions of things.
Given:
As per the table attached below:
F(x) signify the total population when the time was x hour.
So, 160,000 in the function signifies that the population at starting i.e., initial point.

<span>1. 5564÷91
I know that 9 * 6 = 56
5564 rounds to 5600
91 rounds to 9
Since 56/9 = 6, then 5600/90 is the same as 560/9 = 60
The estimate is 60
2. </span><span>5391÷25
5391 sounds to 5400
25 is 1/4 of 100.
That means when you divide by 25, you can divide by 100 and multiply by 4.
5400/100 = 54
54 * 4 = 216
Estimate: 216
3. </span><span>explain how to estimate 498÷12
48/12 = 4
498 is little more than 480, so 498/12 is little more than 40
4. </span><span>which is the closest estimate for 2130÷ 33
A.7 B.17 C.70 D.700
2130/33
Round off the numerator and denominator to
2100/30
Reduce the fraction
210/3
Since I know that 21/3 = 7, then 210/3 = 70
Estimate: 70

![D. \ 408in^2](https://tex.z-dn.net/?f=D.%20%5C%20408in%5E2)
<h2>
Step-by-step explanation:</h2>
This is a square pyramid because it's a solid having a square base. The point up the pyramid is called the apex and is directly above the middle of the square base. The surface area of a solid is the total area of its outer surface. If we unfold this pyramid, we'll get one square and four identical triangles. So the surface are can be calculated as follows:
![s=s_{square}+4s_{triangle}](https://tex.z-dn.net/?f=s%3Ds_%7Bsquare%7D%2B4s_%7Btriangle%7D)
FOR THE SQUARE:
FOR THE TRIANGLE:
![s_{triangle}=\frac{bh}{2} \\ \\ b=12in \\ h=11in \\ \\ s_{triangle}=\frac{12\times 11}{2}=66in^2](https://tex.z-dn.net/?f=s_%7Btriangle%7D%3D%5Cfrac%7Bbh%7D%7B2%7D%20%5C%5C%20%5C%5C%20b%3D12in%20%5C%5C%20h%3D11in%20%5C%5C%20%5C%5C%20s_%7Btriangle%7D%3D%5Cfrac%7B12%5Ctimes%2011%7D%7B2%7D%3D66in%5E2)
Finally:
![s=s_{square}+4s_{triangle} \\ \\ s=144+4(66) \\ \\ s=144+264 \\ \\ \boxed{s=408in^2}](https://tex.z-dn.net/?f=s%3Ds_%7Bsquare%7D%2B4s_%7Btriangle%7D%20%5C%5C%20%5C%5C%20s%3D144%2B4%2866%29%20%5C%5C%20%5C%5C%20s%3D144%2B264%20%5C%5C%20%5C%5C%20%5Cboxed%7Bs%3D408in%5E2%7D)
