L=a+(n-1)d <br><br> solve for n
earnstyle [38]

Answer:

(L-a)/d + 1 = n

Step-by-step explanation:

Let's isolate (n-1), and after that isolate n:

1) subtract a from both sides:  L - a = (n-1)d

2) Divide both sides by d:  (L-a)/d = n-1

3) Add 1 to both sides, to isolate n:            (L-a)/d + 1 = n

The function f(x) = 25(4)^x represents the growth of a bird population every year in a national park. Kyle wants to manipulate t
Natasha_Volkova [10]

f(x)=25(4)^{\frac{x}{2}} will be the function to calculate population every half year.

Further explanation:

The given formula is:

f(x) = 25(4)^x

In the given formula, x represents the amount of time in years. So, in order to convert the given function for yearly calculation of population, to find the population every half year the time will be converted into half. This means that instead of x, x/2 will be used.

So the new function will be:

f(x) = 25(4)^{\frac{x}{2}}

Consider the following sets.
Andrews [41]
A = {x ≥ 3}, B = {x ≤ 1}

So A∪B = {x ≥ 3 or x ≤ 1}

So for x ⊆(1,3), A∪B = ∅

Apparently, (1,3) covers the first option, a will be the answer

In 2010 the town of Applewood had an estimated population of 22,000 people, and its annual growth rate was estimated to be 1.8%.
sladkih [1.3K]

Answer:

The answer in the procedure

Step-by-step explanation:

Let

P------> the population of Applewood

n-----> the number of years since 2010

we have

P(n)=22,000(1.018^{n})

using a graphing tool

see the attached figure

Verify each conclusion

a) The population of Applewood, P(n), equals 0 when n = 0

The conclusion is No

For n=0

The population is equal to P(0)=22,000 people

b) The behavior of the left end of the graph flattens out indicating that as n approaches negative infinity the population of Applewood approaches 0

The conclusion is Yes

see the graph

c) The behavior of the right end of the graph is upward indicating that as n approaches infinity the population of Applewood approaches infinity

The conclusion is Yes

see the graph
