The formula A=23.1 e^{0.0152t} models the population of a US state, A, in millions, t years after 2000.
a. What was the population of the state in 2000 ?
b. When will the population of the state reach 28.3 million?
a. In 2000 , the population of the state was ? million.
We want to study the population formula of a given US state according to exponential equation.
a) 23.1 millions.
b) in 2013 - 2014
What is exponential equation?
The exponential function may be a function denoted by f(x)=\exp or e^. Unless otherwise fixed, the term usually refers to the positive-valued operate of a true variable
Main body:
The population state is:
A = 23.1*e^(0.0153*t)
In millions.
Where t represents the number of years after 2000.
a) For the population at the year 2000, we need to evaluate the function at t = 0 (2000 is 0 years after 2000).
A(0) = 23.1*e^(0.0153*0) = 23.1
The population at year 2000 was 23.1 millions.
b) Now we want to solve:
A(t) = 28.3 = 23.1*e^(0.0153*t)
28.3/23.1 = e^(0.0153*t)
1.23 = e^(0.0153*t)
Now we can apply the natural logarithm to both sides:
ln(1.23) = ln( e^(0.0153*t) )
ln(1.23) = 0.0153*t
ln(1.23)/0.0153 = t = 13.5
Hence, 13.5 years after 2000 the population will be 28.3 million.

True or False :for a fixed value of the standard deviation and a fixed sample size, a confidence interval on the population mean will become wider as the level of confidence increases; for example, from 96% to 99%.
When the level of confidence interval increases from 96% to 99% then the population mean will also become wider for a given fixed value of standard deviation and its fixed sample size, so the given statement is true.
As given in the question,
Let us consider 'σ' be the fixed standard deviation
And 'n' be the fixed sample size
Population mean = [tex]\bar{x}[/tex] ± z ( σ /√n )
Range of confidence interval increases from 96% to 99%
For a fixed standard deviation and sample size range of population mean become wider .
For fixed [tex]\bar{x}[/tex] , standard deviation 'σ' , and sample size 'n' the value of population mean get varied as per the change in confidence interval z-score.

Find how long it takes $2500 to double if it is invested at 6% interest compounded semiannually. Use the formula A=P(1+r/n) to solve the compound interest problem.
It will take approximately years.
(Do not round until the final answer. Then round to the nearest tenth as needed.)
In 11.71 years the amount will double to the principal amount
What is Compound interest:The interest charged on a loan or deposit is known as compound interest. It is the idea that we use the most frequently on a daily basis. Compound interest is calculated for an amount based on both the principal amount and Compounded interest. This is the major distinction between compound and simple interest is this.
The formula used for
Amount, A = P(1+r/n)^ntwhere P = Principal amount
r = Rate of interest in decimal
n = Number of compounds per year
t = Time period
Here from the given data,
Principal amount, p = $ 2500
Rate of interest, r = 6% = 6/100 = 0.06
Number of compounds, n = 2 [ ∵ 12/6 = 2 ]
Here we need to find the time period
Let's assume that after 'n' years the amount will be doubled i.e $ 5000
From the given problem,
Amount, A = 2500(1+0.06/2)²ⁿ
= 2500(1+0.06/2)²ⁿ
= 2500(1 + 0.03)²ⁿ
= 2500 (1.03)²ⁿ
As we assumed after 'n' years the amount is $ 5000
=> 2500 (1.03)²ⁿ = 5000
=> (1.03)²ⁿ = 2
Apply to log on both sides
=> log (1.3)²ⁿ = log 2
=> 2t log (1.3) = log 2
=> 2t = log 2/ log(1.03)
=> 2t = 0.301029996/(0.0128372247)
[ use calculator for log (1.03) and log 2]
=> 2t = 23.4497722
=> t = 11.7248861
=> t = 11.71 ≅ 11 years
Therefore,
In 11.71 years the amount will double to the principal amount

"Use the formula A=P(1+r/n)ⁿt to solve the compound interest problem
Find how long it takes for $ 900 to double if it is invested at 6 % interest compounded monthly.
The money will double in value in approximately years."
After 11.61 years the given principal amount of $ 900 will be double.
What is Compound interest?
Compound interest is interest charged on a loan and is determined by both the principal amount and the rate of interest compounding per year.
The formula for the Amount when compound interest is calculated is given by
Amount, A = P(1+r/n)^nt
P = Principal amount
r = Rate of interest
n = Number of compounds
t = Time period in years
Given:
Principal amount = $ 900
Rate of interest = 6% = 6/100 = 0.06
Number of compounds = 12 [ ∵ compounded monthly]
We need to find the time period
Assume that after 't' years the amount will be doubled
From the given data and formula,
Amount, A = 900(1+0.06/12)^12t
= 900(1+0.06/12)^12t
= 900(1 + 0.005)^12t
= 900 (1.005)^12t
As we assumed after 't' years the amount is double
=> 900 (1.005)^12t = 2 × 900
=> (1.005)^12t = 2
Applying log on both sides
=> log (1.005)^12t = log 2
=> 12t log(1.005) = log 2
=> 12t = log 2/log(1.005)
=> 12t = 0.30108/ 0.00216
=> 12t = 139.888
=> t = 11.61
Hence, after 11.61 years the given principal amount of $900 will be double.

Write the equation of the line that passes through the points (8, 5) and (-8, 1). Put your answer in fully simplified point-slope form, unless it is a vertical or horizontal line.
Answer:
(y - 5) = 1/4 (x - 8)
Step-by-step explanation:
Point-slope form is written in the form:
(y - y) = m (x - x)
Where the two y's and two x's are from the points, and m is the slope. To write the equation, you'd plug your points into the equation and solve for m, the slope.
(1 - 5) = m (-8 - 8)
-4 = m (-16)
m = 4/16 = 1/4
Plug m into the point-slope form equation as well as one of your points, and you have an equation.
