![\huge\boxed{\sf a^2+b^2+c^2 = 19}](https://tex.z-dn.net/?f=%5Chuge%5Cboxed%7B%5Csf%20a%5E2%2Bb%5E2%2Bc%5E2%20%3D%2019%7D)
Step-by-step explanation:
![\sf (a+b+c)^2 = a^2+b^2+c^2 +2(ab+bc+ca)\\\\Put \ a+b+c = 7 \ and \ ab+bc+ca = 15\\\\7^2 = a^2+b^2+c^2 + 2(15)\\\\ 49 = a^2+b^2+c^2 + 30\\\\49 - 30 = a^2+b^2 +c^2\\\\a^2+b^2+c^2 = 19\\\\\rule[225]{225}{2}](https://tex.z-dn.net/?f=%5Csf%20%28a%2Bb%2Bc%29%5E2%20%3D%20a%5E2%2Bb%5E2%2Bc%5E2%20%2B2%28ab%2Bbc%2Bca%29%5C%5C%5C%5CPut%20%5C%20a%2Bb%2Bc%20%3D%207%20%5C%20and%20%5C%20ab%2Bbc%2Bca%20%3D%2015%5C%5C%5C%5C7%5E2%20%3D%20a%5E2%2Bb%5E2%2Bc%5E2%20%2B%202%2815%29%5C%5C%5C%5C%2049%20%3D%20a%5E2%2Bb%5E2%2Bc%5E2%20%2B%2030%5C%5C%5C%5C49%20-%2030%20%3D%20a%5E2%2Bb%5E2%20%2Bc%5E2%5C%5C%5C%5Ca%5E2%2Bb%5E2%2Bc%5E2%20%3D%2019%5C%5C%5C%5C%5Crule%5B225%5D%7B225%7D%7B2%7D)

Answer: 15, because it is 16-1
Answer:
Sequence : ![a_n=8(\frac{1}{2})^{n-1}](https://tex.z-dn.net/?f=a_n%3D8%28%5Cfrac%7B1%7D%7B2%7D%29%5E%7Bn-1%7D)
Rate of change : -3
Step-by-step explanation:
It is given that the sequence represents by the points (1,8), (2,4), (4,1) and (5,0.5).
We know that the
represent the point (n,k). So, we have
It is clear that the above sequence is a geometric sequence because it has common ratio
.
First term :
Common ratio :
The nth term of a G.P. is
Therefore, the required sequence is
.
We need to find the average rate of change from n = 1 to n = 3.
Therefore, the average rate of change from n = 1 to n = 3 is -3.
