Actually, you have to find four missed terms of geometrical sequence. Denote
and r - ratio, then
.
Since
, you have that
, then
.
Now substitude r=2 in each of unknown 4 terms:
.
Answer: four geometric means between 25 and 800 are 50, 100, 200, 400.
Since you have two numbers that have a (x) at the ends of them, you add those first then add seven which will end up being 9x+7
Answer:
Step-by-step explanation:
Calculus....finally something FUN to answer!
This is integration, but here you have the area under the curve, you just don't have the upper bound. Setting that problem up looks like this:
and using the First Fundamental Theorem of Calculus, that will integrate to look like this:
from 1 to b and applying the FTC:
Multiplying everything by 2 to get rid of the denominators gives you:
![56=7b^2-7\\\\56=7(b^2-1)\\8=b^2-1\\9=b^2\\b=3](https://tex.z-dn.net/?f=56%3D7b%5E2-7%5C%5C%5C%5C56%3D7%28b%5E2-1%29%5C%5C8%3Db%5E2-1%5C%5C9%3Db%5E2%5C%5Cb%3D3)
