$108.88 taken off >> $221.07 total
Answer:
Step-by-step explanation:
This graph is digits going by eigths.
For 2 1/2, mark a dot right between the 2 and 3, on the fourth tick mark.
For -3/8, go left of 0 3 tick marks. (Right between 0 and -1).
For -1 3/4, go right of -2 by 2 tick marks. (Right between -2 and -1)
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:
x = 11.7
Step-by-step explanation:
3(x + 3) = 4(4 + 7) => intersecting secant theorem
3(x + 3) = 4(11)
3x + 9 = 44
3x + 9 - 9 = 44 - 9
3x = 35
x = 11.7
