What is meant by exponential growth?A process called exponential growth sees a rise in quantity over time. It happens when a quantity changes at an instantaneous rate that is proportionate to the quantity itself with respect to time.
Data patterns that exhibit exponential growth exhibit quicker rate of expansion over time. Compounding produces exponential returns in the financial world. Savings accounts with a compound interest rate have the potential to expand exponentially.
The population growth will be modeled using exponential growth:
f(x) = a(b[tex])^t[/tex]
where:
a be the initial value
b be the growth rate
Substitute the values in the above equation, we get
f(x) = 1.3(1.04[tex])^t[/tex]
The population after 10 years will be:
f(x) = 1.3(1.04[tex])^{10[/tex]
simplifying the equation, we get
f(x) = 1.9243
Therefore, the population in 10 years will be 1.9243 million.

I have 460 less than dotun.altogether we have 1280.how much do we each have
The main unknown at this point is "the number of adult tickets." The "number of children's tickets" is another factor that is unknowable. In order to assign two variables, do as follows:
Let a = # of adult tickets
and c = # of children's tickets.
What is meant by variables?Any traits, figures, or amounts that may be gauged or counted are considered variables. Another name for a variable is a data item. Variables include things like age, sex, business income and expenses, birthplace, capital expenditures, class grades, eye color, and vehicle type.
Setting up the equations using the unknowns that follow the word problem is the next step. Here are the details:
There are 460 tickets total because there are an adult ticket and a child ticket.
a + c = 460.
Now that we know we want to find the number of adult tickets, we can translate the basic equation a + c = 460 into terms of a:
a + c = 460
-a = -a (For example, use -a to delete a from the left side of the equation on either side.)
c = 460 - a
We can now enter the equation c into the other equation, 8.75a + 3.50c = 3143, since we have the equation c expressed in terms of a.
Now, we need to find the value of c in the first equation so that we can plug it into the second equation:
292 + c = 460
-292 = -292
c = 168
(8.75 × 292) + (3.50 × 168) = 3143
2555 + 588 = 3143
3143 = 3143
Therefore, We each have 3143
The complete question is:
For a show adult tickets are $8.75 and children's tickets are $3.50. 460 tickets were sold for a total of 3143 how many adults tickets were sold?
Adult ticket = 8.75
child ticket = 3.50
460 tickets we're sold totaling 3143
how many adults tickets were sold

What does it mean if the question asks "translate triangle ABC with the vector of <-5, 2>
To translate a triangle with vector (-5/2), you need to subtract 5/2 from the x-coordinate and add 2 to the y-coordinate of each vertex of the triangle. This will move the triangle 5 units to the right and 2 units up.
What is triangle?A triangle is a polygon since it has three sides and three vertices. It is one of the basic geometric shapes. The name given to a triangle containing the vertices A, B, and C is Triangle ABC. A unique plane and triangle in Euclidean geometry are discovered when the three points are not collinear. Three sides and three corners define a triangle as a polygon. The triangle's corners are defined as the locations where the three sides converge. 180 degrees is the result of multiplying three triangle angles.
To translate a triangle with a vector, you can use the vector to adjust the coordinates of the triangle's vertices.
For example, if the triangle has vertices at (x1, y1), (x2, y2), and (x3, y3), you can translate it by the vector (-5/2) by subtracting 5/2 to the x-coordinates of the vertices. The new coordinates of the translated triangle would be (x1-5/2, y1), (x2-5/2, y2), and (x3-5/2, y3).
This will move the triangle 5/2 units to the left along the x-axis.
It is important to note that the translation vector you provided only has one component, which is -5/2. Since the vector only has x component, the translation will only occur along the x-axis and the y-coordinate of the vertices will not change.

150% ×_____ = $6.75 find the unknown
Answer:
The answer is $4.50.
Step-by-step explanation:
To solve this problem, divide the result ($6.75) by the percentage (150%). This gives you the original number which was multiplied by the percentage. So,
$6.75 / 150% = $4.50.
Answer:
$4.50
Step-by-step explanation:
150% × □ = $6.75
First, we can rewrite 150% as the fraction 3/2.
[tex]\dfrac{3}{2} \times \square = \$ 6.75[/tex]
Then, we can also rewrite 6.75 as the fraction 27/4.
[tex]\dfrac{3}{2} \times \square = \$ \, \dfrac{27}{4}[/tex]
Next, we can isolate the unknown by multiplying both sides by 2/3 (the reciprocal of 3/2).
[tex]\left(\dfrac{2}{3} \right)\left(\dfrac{3}{2} \times \square \right) = \left(\$ \, \dfrac{27}{4}\right)\left(\dfrac{2}{3} \right)[/tex]
After that, simplify by multiplying out the numerators and denominators on the right side of the equation.
[tex]\square = \$ \, \dfrac{27 \times 2}{4 \times 3}[/tex]
[tex]\square = \$ \, \dfrac{54}{12}[/tex]
Finally, simplify the expression on the right side to a decimal form.
[tex]\square = \$ \, \dfrac{54 \div 2}{12 \div 2}[/tex]
[tex]\square = \$ \, \dfrac{27 \div 3}{6 \div 3}[/tex]
[tex]\square = \$ \, \dfrac{9}{2}[/tex]

Determine if the sequence below is arithmetic or geometric and determine the common difference / ratio in the simplest form 12,7,2,...
Answer: common difference = -5
Step-by-step explanation:
This is an arithmetic progression. The common difference will be gotten by subtracting the 1st term from the 2nd term. This will be:
1st term = 12
2nd term = 7
3rd term = 2
Common difference = 7 - 12 or 2 - 7 = -5
It isn't an geometric progression as the ratio isn't thesame
= 2nd term / 1st term
= 7/12
= 3rd term / 2nd term
= 2/7
Therefore, it's an arithmetic progression with difference of -5

Answer:
C.
Step-by-step explanation:
To find the equation of the line that goes through the points (5, 3) and (-1, 2), we can use the point-slope form of a linear equation. The point-slope form is given by:
y - y1 = m(x - x1)
where (x1, y1) is a point on the line, and m is the slope of the line.
To find the slope of the line, we can use the following formula:
m = (y2 - y1)/(x2 - x1)
Plugging in the coordinates of the two points, we get:
m = (2 - 3)/(-1 - 5) = -1/6
Substituting this value of m and the coordinates of one of the points into the point-slope form, we get:
y - 3 = -1/6(x - 5)
This simplifies to:
6x + y - 13 = 0
Therefore, the equation of the line is:
6x + y - 13 = 0

How do you identify the solutions in solving linear inequalities in two variables *?
To identify the solutions in solving linear inequalities in two variables, you can first graph the equation on a coordinate plane. Then, you can use the boundary line to identify which regions of the plane satisfy the inequality.
Any points in the shaded regions will be solutions to the inequality. Additionally, you can use the boundary line to identify the points that are not solutions by finding the points that lie on the boundary line.
Example:
x + 2y ≥ 4
The graph of this inequality is a line with a slope of -2/1 and a y-intercept of 4/2. The line will be shaded on the side of the line containing the greater values, which in this case is the side containing the origin.

Answer:
There is no answer.
Step-by-step explanation:
-2(11 - 12x) = -4(1-6x)
First you need to simplify the equation, using distributive property.
Distribute -2 to the numbers within the parentheses.
-2*11 = -22
-2*-12x =24x
= 24x - 22
Then distribute -4 among 1 and -6.
-4*1 =-4
-4*-6x = +24x
= 24x - 4
And because
24x - 22 does NOT equal 24x - 4
There is no answer because they are not equivalent, making the equation itself false/untrue.

Raina is going to rent a truck for one day. There are two companies she can choose from, and they have the following prices. Company A charges and allows unlimited mileage. Company B has an initial fee of and charges an additional for every mile driven. For what mileages will Company A charge less than Company B
For mileages of 40 or less, Company A will charge less than Company B. For mileages above 40, Company B will charge less than Company A.
To compare the prices of the two companies, we need to determine the total cost for each company at different mileage.
For Company A, the total cost is the initial fee of $50. This is a fixed price, regardless of the mileage driven.
For Company B, the total cost is the initial fee of $30 plus the additional cost per mile driven. To calculate this, we can use the formula:
Total cost = initial fee + (mileage * additional cost per mile)
For Company B, this would be:
Total cost = $30 + (mileage * $0.50)
To find out when Company A charges less than Company B, we need to compare the total costs of the two companies at different mileage. We can set up the following inequality:
$50 <= $30 + (mileage * $0.50)
To solve for mileage, we need to isolate it on one side of the inequality. To do this, we can subtract $30 from both sides:
$20 <= (mileage * $0.50)
Then, we can divide both sides by $0.50:
40 <= mileage
So for mileages of 40 or less, Company A will charge less than Company B. For mileages above 40, Company B will charge less than Company A.
