Answer:
177
Step-by-step explanation:
This scenario can be modeled as an <u>exponential function</u>.
General form of an exponential function: 
where:
- a is the initial value (y-intercept)
- b is the base (growth/decay factor) in decimal form
- x is the independent variable
- y is the dependent variable
If b > 1 then it is an increasing function
If 0 < b < 1 then it is a decreasing function
If the number of trees <u>increase</u> by <u>10% each year</u>, then the number of trees each year will be 110% of the number of trees the previous year. Therefore, the <u>growth factor is 110%</u>.
Given:
- a = 100 trees
- b = 110% = 1.10 (in decimal form)
- x = time (in years)
- y = number of trees in the orchard
Substituting the given values into the function:

(where x is time in years and y is the number of trees in the orchard)
To find how many trees are in the orchard in the 6th year, input x = 6 into the found equation:

Therefore, Martin had 177 trees in his orchard in the sixth year.
Sorry got it wrong I didn't know if you had to subtract:>
Answer:
12.57 yards
Step-by-step explanation:
The circumference of a circle is denoted by:
, where d is the diameter.
Here, we are given the diameter, so d = 4.
Now, plug this into the equation:

≈ 12.57
The circumference is about 12.57 yards.
Hope this helps!
Answer:
Lavania observed 39 fruit flies after 6 days of observation
Step-by-step explanation:
Let x be the number of fruit flies on the first day of Lavania's study.
After 6 days she had nine more than five times as many fruit flies as when she began the study.
Five times as many fruit flies as when she began the study = 5x
Nine more than five times as many fruit flies as when she began the study=5x+9
The expression to find the population of fruit flies Lavania observed after 6 days is 5x+9
If she observes 20 fruit flies on the first day of the study, then x=6, then
