Answer:
87.5
Step-by-step explanation:
Add all of them up and you get D. Can you plz put brainliest answer I'm trying to rank up
Given:
Initial population = 100 algae
Growth rate = 30% per day.
Time = 5 days
To find:
The future amount of population.
Solution:
The exponential growth model is

where, a is the initial value, r is the rate of interest in percent and t is time period.
Substituting the given values, we get


Now, solve this.



Therefore, the future value is 371.293 algae.
Answer:
The answer to your question is the letter D. (x - 11)² + (y - 6)² = 72
Step-by-step explanation:
Data
Equation = ?
Center = (11, 6)
Point = (17, 12)
Process
1.- Calculate the length of the radius using the distance between two points formula.
d = 
x1 = 11 y1 = 6
x2 = 17 y2 = 12
-Substitution
d = 
d = 
d = 
d = 
radius = 
2.- Write the equation of the formula
(x - 11)² + (y - 6)² = (
)²
Result
(x - 11)² + (y - 6)² = 72
