Answer:
The correct option is;
C) 6554
Step-by-step explanation:
The given data are;
Day, Amount of change in Bacteria
1, 2
2, -8
3, 32
4, -128
Given that the data follows a geometric sequence, we have;
The first term of the series = 2, the common ratio = -4, the sum of a geometric progression is given by the following formula;
![S_n = \dfrac{a \times \left (r^n - 1\right )}{r - 1}](https://tex.z-dn.net/?f=S_n%20%3D%20%5Cdfrac%7Ba%20%5Ctimes%20%5Cleft%20%28r%5En%20-%201%5Cright%20%29%7D%7Br%20-%201%7D)
Which gives;
![S_7 = \dfrac{2 \times \left ((-4)^7 - 1\right )}{(-4) - 1} = \dfrac{2 \times \left (-16384- 1\right )}{-4 - 1} = \dfrac{2 \times \left (-16385\right )}{-5} = 6554](https://tex.z-dn.net/?f=S_7%20%3D%20%5Cdfrac%7B2%20%5Ctimes%20%5Cleft%20%28%28-4%29%5E7%20-%201%5Cright%20%29%7D%7B%28-4%29%20-%201%7D%20%3D%20%20%5Cdfrac%7B2%20%5Ctimes%20%5Cleft%20%28-16384-%201%5Cright%20%29%7D%7B-4%20-%201%7D%20%20%3D%20%5Cdfrac%7B2%20%5Ctimes%20%5Cleft%20%28-16385%5Cright%20%29%7D%7B-5%7D%20%3D%206554)
Therefore, the correct option is C) 6554.
From question given
Radius r = 5.5 ml
Volume = ?
We know that
Volume = The formula is 4/3 × π × radius3.
= 4/3 × 3.14× 5.5^3
= 696.557 ml^3 answer
Good morning/afternoon!
It might affect the demand of drys because if you need a fast way of drying cloths without hanging them on a clothesline you need a dryer so the more and more people buy washing machines the more and more people need a dryer
