Answer:
The red drone will be at the same height as the blue drone at 33.33 seconds, therefore higher at 34 seconds.
Step-by-step explanation:
Red drone = 100 + 8*seconds
Blue drone = 180 + 5*seconds
100 + 8*seconds = 180 + 5*seconds
3*seconds = 100
seconds = 33.33
Answer: 
Step-by-step explanation:
Get rid of parentheses: 
Add all the numbers together, and all the variables: 
Move all terms containing x to the left, all other terms to the right:
The sum of the sum notation ∞Σn=1 2(1/5)^n-1 is S= 5/2
<h3>How to determine the sum of the notation?</h3>
The sum notation is given as:
∞Σn=1 2(1/5)^n-1
The above notation is a geometric sequence with the following parameters
- Initial value, a = 2
- Common ratio, r = 1/5
The sum is then calculated as
S = a/(1 - r)
The equation becomes
S = 2/(1 - 1/5)
Evaluate the difference
S = 2/(4/5)
Express the equation as products
S = 2 * 5/4
Solve the expression
S= 5/2
Hence, the sum of the sum notation ∞Σn=1 2(1/5)^n-1 is S= 5/2
