The annual births that Maine should expect is about 18,164

Given,

The average annual birth in Lowa = 37,785

The average annual death in Lowa = 30,530

The average annual death in Maine = 14,676

Maine is proportional to Lowa in annual births to deaths.

We have to find the annual births that Maine should expect;

Here,

Maine is proportional to Lowa in annual births to deaths.

That is,

Annual birth in Lowa :  Annual death in Lowa = Annual birth in Maine : Annual death in Maine

37,785 : 30, 530 = x : 14,676

x = (37,785 x 14,676) / 30,530

x = 18, 164

That is,

The annual births that Maine should expect is about 18,164

What is the slope of line?

Given two line-side coordinates, use the slope formula to determine the slope of the line. The slope is defined as the ratio of the change in the y values to the change in the x values using the formula m=(y2-y1)/(x2-x1). x1 and y1 are represented by the first point's coordinates. The second points are located at x2, y2, and their locations. Whichever point you choose to classify as the first and which as the second doesn't matter.

For the first point, we would have 9=3k;

So we have k=9/3.

For the second point, we would have 13=4k;

this would mean that k=13/4.

And for 3rd point, we would have 23 =7k;

Checking using proportions shows us that 11/7 does not equal 13/4:

cross multiply.

Since this is untrue, k is not a constant and y does not change in direct proportion to x.

Hence the equation of the for the different points are determined.

The number of months that it would take for the price of the gallon to get to 1.90 dollars is 20 months.

We have the following details with which we are to solve this problem.

The price of gas is given as $1.79

The rate of increase is given as 0.3% = 0.003

We are to find the value for when it would be $1.90

The formula that would be used to solve this is given as

[tex]F = P * (1 + r)^n[/tex]

Where f = final value

p = present value

r = rate

n = number of months

From the question

f = 1.90

p = 1.79

r = 0.03

we have to put these values in the formula that we have here

[tex]1.9 = 1.79 * (1 + 0.03)^n[/tex]

[tex]1.9 = 1.79 * (1.003)^n[/tex]

Divide through by 1.79

[tex]\frac{1.9}{1.79} = (1.003)^n[/tex]

take the ln of both sides

[tex]ln\frac{1.9}{1.79} = nln(1.003)[/tex]

We have to simplify the equation above from this stage

0.05968 = n0.002995

The linear equation is 10C+13A=859 and number of children ticket is 17.

What is linear equation ?

 A linear equation is also known as a one degree equation. The linear equation's highest power is 1. Linear equations are equations with variables on both sides that are multiplied by a constant.

Let us take Number of children's ticket as C and number of adult's ticket as A.

Here cost price of one adult ticket = $13

Cost price of one children ticket =$10

A total of $859 was collected in ticket sales for the 7:15PM show.

Total cost price = cost price of children ticket + cost price of adult ticket

=> Total cost price = 10*C+13*A

=> 859=10C+13A

Hence the linear equation is 10A+13A=859.

Here If number of adult ticket = 53. Then

=> 13*53+10C=859

=>689+10=859

=>10C= 859-689=170

=> C=170/10 = 17.

Hence the number of children ticket is 17.

According to the given question, the required solution would be as:

The period used = 4 years,

Rate Used = 6%

We know that,

PV factor = 1/(1+r)ⁿ

Here r = 6% = 6/100 = 0.06, and n = 4

PV factor = 1/(1+0.06)⁴

PV factor = 1/(1.06)⁴

PV factor = 0.792

PV of the amount desired at end of the period = FV/(1+r)ⁿ

Here FV = $8,900.00

PV of the amount desired at end of the period = 8,900.00/(1+0.06)⁴

PV of the amount desired at end of the period = 8,900.00/(1.06)⁴

PV of the amount desired at end of the period = $7049.63

The angle θ = 170° and  θ = 350°  have the same Sine and Cosine as 10° respectively

Since the Sine and Cosine of angle 10° are positive

In order to find an angle θ with 0° < θ < 360° that has the same Sine and

Cosine as 10°, we have to check the quadrants in Trigonometry where Sine and Cosine are positive

1st quadrant (0° - 90°) => Sine is positive (10° is here)

2nd quadrant (91° - 180°) => Sine is positive

3rd quadrant (181° - 270°) => None is postive

4th quadrant (271° - 360°) => Cosine is positive

We will consider the 2nd and 4th quadrants:

2nd quadrant: Sine 10° = Sine (180 - 10)° = Sine 170°

4th quadrant: Cosine 10° = Cosine (360 - 10)° = Cosine 350°

Therefore, θ = 170 degrees and  θ = 350 degrees have the same Sine and Cosine as 10° respectively
