Answer:
Step-by-step explanation:
Assumed the starting point is the sea level 0.
<u>After 2.8 min the diver is at position:</u>
- 20 1/2 * 2.8 =
- 20.5 * 2.8 =
- 57.4 feet below sea level
<u>The position change after next 2 minutes:</u>
<u>The position of the diver after 4.8 min:</u>
- 57.4 - 50 = 7.4 feet below sea level
The slope m of a line passing through points P(a, b) and Q(c, d) is found using the formula:
![m= \frac{b-d}{a-c}](https://tex.z-dn.net/?f=m%3D%20%5Cfrac%7Bb-d%7D%7Ba-c%7D%20)
.
Thus, the slope in A is
![m= \frac{12-2}{-4-(-10)}=\frac{10}{6}=\frac{5}{3}](https://tex.z-dn.net/?f=m%3D%20%5Cfrac%7B12-2%7D%7B-4-%28-10%29%7D%3D%5Cfrac%7B10%7D%7B6%7D%3D%5Cfrac%7B5%7D%7B3%7D)
.
The slope in B is
![m= \frac{-4-10}{6-18}=\frac{-14}{-12}=\frac{7}{6}](https://tex.z-dn.net/?f=m%3D%20%5Cfrac%7B-4-10%7D%7B6-18%7D%3D%5Cfrac%7B-14%7D%7B-12%7D%3D%5Cfrac%7B7%7D%7B6%7D)
.
Now, to compare 7/6 to 5/3, we can write the second fraction as 10/6.
So, the slope in A is larger than the slope in B.
Answer: A
Answer: A) 23.5%
Explanation: 340-260= 80
80/340=0.2352x100=23.5
