SOLUTION:
Step 1:
In this question, we have the following:
Step 2:
Part A:
The function that models the population of Star, ID in years since 2000 is:
[tex]f(x)\text{ = 1800 }(1\text{ + }\frac{9.9}{100})^t[/tex]Part B :
Use your function to predict the population of Star, ID in 2050
[tex]\begin{gathered} \text{Given } \\ f(x)\text{ = 1800 ( 1 + }\frac{9.9}{100}^{})^t \end{gathered}[/tex]The year 2050 means that t= 50, we have that:
[tex]\begin{gathered} f(x)=\text{ 1800 ( 1 + }\frac{9.9}{100})^{50} \\ f(x)=1800X(1+0.099)^{50} \\ f(x)\text{ =}1800(1.099)^{50} \\ f(x)=201,909.6734 \\ f(x)\approx\text{ 201, 910 ( to the nearest whole number)} \end{gathered}[/tex]Part C:
The function:
[tex]g(x)\text{ = 11000 ( 1}.056)^x[/tex]models the population of Eagle, ID in years (x) since 2000.
Which city is growing faster? How do you know?
Answer:
From this equation, we can see that the growth rate is 5.6% annually.
Comparing this, with the initial function:
[tex]f(x)=1800(1.099)^{50}[/tex]We can see that the annual growth rate of f(x) is 9.9 %
CONCLUSION:
The population of Star ID, with the function, g (x) has a faster growth rate.
which of the following expressions does not represent 7 + 7 + 7 + 7 + 7
7 + 7 + 7 + 7 + 7 means 7 is added 5 times
It could be written as

The width of a rectangle is 5 feet, and the diagonal length of the rectangle is 12 feet. Which measurement is closest to the length of this rectangle in feet?
The measurement is closest to the length of the rectangle is √119 ft.
What is the measure of the length of the given rectangle?Pythagorean theorem states that the "square on the hypotenuse of a right-angled triangle is equal in area to the sum of the squares on the other two sides.
It is expressed as;
c = √( a² + b² )
Where c is the diagonal that divides the rectangle into two equal triangle, a and b are the other legs of the triangle.
Given the data in the question;
With ( First leg ) a = 5ftDiagonal c = 12ftSecond leg b = ?Plug the values into the formula and solve for b.
12ft = √( (5ft)² + b² )
Take the square of both sides
( 12ft )² = (5ft)² + b²
144ft² = 25ft² + b²
b² = 144ft² - 25ft²
b² = 119ft²
b = √( 119ft² )
b = √119 ft
Therefore, the measure of the length is √119 ft.

What is distance?
Distance is a measurement of how far apart two things or points are, either numerically or occasionally qualitatively. Distance can refer to a physical length in physics or to an estimate based on other factors in common usage.
As given, Allison drove home at 58 mph, but her brother Austin, who left at the same time, could drive at only 46 mph. Allison arrived, Austin still had 24 miles to go.
Let t be the time they drove.
Then you have this "distance" equation
58t = 46t + 24
saying that both parts of the equation represent the same distance. Then
58t - 46t = 24
12t = 24
t = 2 hours.

The marked price of an article is Rs.2080. After allowing d% discount and levying(d-2)% VAT,the cost of the article becomes Rs 1997.84. find the discount amount and VAT amount
The discount rate is 15% and the VAT rate is 13%
What is the value of the discount?The following can be deduced:
MP = 2080
Discount = d%
VAT = (d-2)%
Cost = 1997.84
Apply discount:
2080 - d% = 2080*(1 - 0.01d)
Add VAT:
2080*(1 - 0.01d) + (d - 2)%
2080*(1 - 0.01d) * (1 + (d -2)/100)
2080*(1 - 0.01d) * (0.98 + 0.01d)
= 1997.84
(1 - 0.01d)(0.98 + 0.01d) = 1997.84/2080
0.98 + 0.01d - 0.0098d - 0.0001d²
= 0.9605
- 0.0001d² + 0.0002d + 0.98- 0.9605 = 0
0.0001d²- 0.0002d - 0.0195 = 0
d² - 2d + 195 = 0
Solving the quadratic equation we get:
d = 15
Therefore discount is 15%
VAT rate = d - 2 = 15% - 2% = 13%

I need help with my mathWrite the slope-intercept form of the equation of each line
Answer:
y = -1
Explanation:
The slope-intercept form of the equation of a line has the form:
y = mx + b
Where m is the slope and b is the y-intercept.
The slope can be calculated as:
[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]Where (x1, y1) and (x2, y2) are the coordinates of two points in the line.
So, replacing (x1, y1) by (1, -1) and (x2, y2) by (2, -1), we get:
[tex]m=\frac{-1-(-1)}{2-1}=\frac{-1+1}{1}=\frac{0}{1}=0[/tex]On the other hand, the y-intercept is the point where the line crosses the y-axis. So, the y-intercept is -1.
Finally, the equation of the line in the slope-intercept form is:
y = 0x - 1
y = -1
So, the answer is y = -1

The truck can haul 1102 pounds.
According to the question,
We have the following information:
A Ford F-150 truck is considered a half-ton truck because that is how much it can haul.
(More to know: ton, pounds and kilograms are the most commonly used units for measuring weight.)
Now, we already have the knowledge that 1 ton is equal to 1000 kilograms.
So, half ton will make 500 kg.
Now, in order to convert this into pounds, we will multiply 500 kg by 2.205 because we know that 1 kg makes 2.205 pounds.
1 kg = 2.205 pounds
500 kg = (500*2.205) pounds
500 kg = 1102.5 pounds

Use arithmetic operations to isolate y in the second equation:
[tex]\implies -12x+3y+12x=3+12x[/tex]

As parallel lines never intersect, there are no solutions to this system and the system is said to be inconsistent.
if 5% of all vehicles travel less than 39.13 m/h and 10% travel more than 73.25 m/h, what are the mean and standard deviation of vehicle speed? (round your answers to three decimal places.) mean standard deviation
The mean is 58.319 m/h and the standard deviation is 11.665 m/h of the vehicle speed if 5% of all vehicles travel less than 39.13 m/h and 10% travel more than 73.25 m/h.
The mean and standard deviation of the vehicle speed can be calculated by using the formula for z-score.
The z-score of measure X can be given as;
Z = X - μ / σ
In this case, 39.13 m/h is the 5th percentile; therefore when X = 39.13, Z has a p-value of 0.05, hence Z = -1.645
Z = X - μ / σ
-1.645 = (39.13 - μ) / σ
39.13 - μ = -1.645σ
μ = 39.13 + 1.645σ
Additionally, 73.25 m/h is the 90th percentile (100 - 10 = 90), therefore when X = 73.25, Z has a p-value of 0.9, hence Z = 1.28
1.28 = (73.25 - μ) / σ
73.25 - μ = 1.28σ
μ = 73.25 - 1.28σ
We can find the standard deviation by equalling both equations as follows;
39.13 + 1.645σ = 73.25 - 1.28σ
1.645σ + 1.28σ = 73.25 - 39.13
2.925σ = 34.12
σ = 34.12/2.925 = 11.665 m/h
Now the mean can be calculated as follows;
μ = 73.25 - 1.28σ
μ = 73.25 - 1.28(11.665)
μ = 58.319 m/h

According to the theorem, the corresponding angles, formed by a transversal on a pair of parallel sides, are always equal.
Also, the sum of angles on a straight line is 180 degree.
The angles 5 and 7 constitute a pair of corresponding angles, formed by the transversal 'r' on the pair of parallel sides 'p' and 'q'. So they must be equal,
[tex]\begin{gathered} \angle5=\angle7 \\ \angle5=131^{\circ} \end{gathered}[/tex]The angles 4 and 5 constitute a straight line, so they must add up to be 180 degrees,
[tex]\begin{gathered} \angle4+\angle5=180^{\circ} \\ \angle4+131^{\circ}=180^{\circ} \\ \angle4=180^{\circ}-131^{\circ} \\ \angle4=49^{\circ} \end{gathered}[/tex]Thus, the angle 4 measures 49 degrees.
