find - 4 - 2 1/2 expression on the number line by drawing an arrow
The resulting arrow should end at -6 1/2. This is because -4 - 2 1/2 is equal to -6 1/2.
In mathematics, an expression is a combination of numbers, variables, and operators that can be evaluated to produce a value. Expressions can be simple or complex and are used to represent mathematical relationships and operations.
How to determine the expression?To find -4 - 2 1/2 expression on the number line by drawing an arrow, we need to start at -4 and then move left by 2 1/2 units.
To do this, we can draw an arrow starting at -4 and then mark off 2 1/2 units to the left. One way to represent 2 1/2 units is to divide the space between -4 and -5 into two equal parts, and then mark off one of those parts.
The resulting arrow should end at -6 1/2. This is because -4 - 2 1/2 is equal to -6 1/2.
Here's an example of what the arrow would look like:

Θ(x) = tan⁻¹(5x / (4(x - 13))), and Θ is maximized when the distance the cow must stand from the billboard x₀ = 26.
How to determine angle and distance?To find Θ, use similar triangles. Let the distance from the cow to the top of the billboard be h. Then, using similar triangles:
h / x = 5 / (x - 13)
Solving for h:
h = 5x / (x - 13)
The vertical angle subtended by the billboard at the cow's eye is equal to the angle whose tangent is given by:
tan(Θ) = h / 4
Substituting for h:
tan(Θ) = 5x / (4(x - 13))
To maximize Θ, find the value of x that maximizes tan(Θ). Taking the derivative of tan(Θ) with respect to x and setting it equal to zero:
d/dx (tan(Θ)) = 5(52 - 26x) / (4(x - 13))² = 0
Solving for x:
x₀ = 26
Substituting x₀ into the expression for Θ:
Θ(x₀) = tan⁻¹(5(26) / 4(13)) = tan⁻¹(5/2)
Therefore, Θ(x) = tan⁻¹(5x / (4(x - 13))), and Θ is maximized when x₀ = 26.

After 8 years, Fabian earned $1430 in simple interest from a CD into which he
initially deposited $5500. What was the annual interest rate of the CD?
A. 0.48%
B. 4.8%
C. 0.325%
D. 3.25%
Answer:
D. 3.25%
Step-by-step explanation:
The formula for simple interest is:
I = Prt
where I is the interest earned, P is the principal, r is the annual interest rate, and t is the time in years.
We are given that:
I = $1430
P = $5500
t = 8 years
Substituting the values:
$1430 = $5500 * r * 8
Simplifying, we get:
r = $1430 / ($5500 * 8)
r = 0.0325 or 3.25%
Therefore, the annual interest rate of the CD is 3.25%.
Answer: D. 3.25%

In the xy-plane, what is the y-intercept of the graph of the equation y=6(x-1/2)(x+3)?
Answer:
The y-intercept of the graph of the equation is -9. This means that the graph crosses the y-axis at the point (0, -9).
Step-by-step explanation:
To solve this question, we need to plug in x = 0 into the given equation and simplify. We get:
y = 6(0 - 1/2)(0 + 3) y = 6(-1/2)(3) y = -9
Therefore, the y-intercept of the graph of the equation is -9. This means that the graph crosses the y-axis at the point (0, -9).
If the dealership you are buying the car from is offering 6.3% interest on a 5 year loan, what will your monthly payment be? How am I able to solve this when the selling price is $56,937.
Answer:
Step-by-step explanation:
To calculate the monthly payment on a loan, you can use the formula for the monthly payment on an annuity: P = (r * PV) / (1 - (1 + r)^(-n)), where P is the monthly payment, r is the monthly interest rate, PV is the present value of the loan (i.e., the amount borrowed), and n is the total number of monthly payments.
In this case, the amount borrowed is $56,937 and the interest rate is 6.3% per year. To convert this to a monthly interest rate, we divide by 12: r = 0.063 / 12 = 0.00525. The loan term is 5 years, so the total number of monthly payments is n = 5 * 12 = 60.
Substituting these values into our formula for the monthly payment, we get: P = (0.00525 * 56937) / (1 - (1 + 0.00525)^(-60)) ≈ $1102.53. So, the monthly payment on this loan would be approximately $1102.53.

13pi/6 terminal point
The terminal point of 13π/6 is (-√3/2, 1/2) by using unit circle.
What are the quadrants of a graph?The quadrants of a graph are the four sections that divide the coordinate plane. The quadrants are numbered in a counterclockwise direction starting from the positive x-axis.
1. Quadrant I is located in the upper-right section and contains points with positive x and y-coordinates.
2. Quadrant II is located in the upper-left section and contains points with negative x-coordinates and positive y-coordinates.
3. Quadrant III is located in the lower-left section and contains points with negative x and y-coordinates.
4. Quadrant IV is located in the lower-right section and contains points with positive x-coordinates and negative y-coordinates.
The quadrants are useful for determining the signs of coordinates, angles, and for plotting points on a graph.
To find the terminal point of 13π/6, we can start by recognizing that this angle is greater than 2π, which is one complete revolution around the unit circle.
To bring the angle back within one revolution, we can subtract 2π, which gives us 13π/6 - 2π/1 = 13π/6 - 12π/6 = 1π/6.
The angle 1π/6 is in the standard position between the positive x-axis and the first quadrant. The reference angle is π/6, which is the angle between the terminal side and the x-axis.
Since the angle is in the 2nd quadrant, the x-coordinate will be negative and the y-coordinate will be positive. Using the unit circle, we can find the values of sine and cosine at π/6 and then negate the value of cosine since the angle is in the second quadrant.
cos(π/6) = √3/2
sin(π/6) = 1/2
Therefore, the terminal point of 13π/6 is (-√3/2, 1/2).

The reduced form of the matrix is [tex]\begin{bmatrix}1 &-\frac{4}{7} &\frac{4}{7} \\0& 11& 79\end{bmatrix}[/tex]
A matrix is a rectangular array of numbers arranged in rows and columns. In linear algebra, matrices can be used to represent linear transformations and solve systems of linear equations.
In the given matrix, we need to perform a row operation to get a 1 in row 1, column 1. Row operations are operations performed on the rows of a matrix to transform it into another matrix that is equivalent in terms of solutions to a system of linear equations.
The three types of row operations are:
Swapping two rows.
Multiplying a row by a non-zero constant.
Adding a multiple of one row to another row.
To perform this row operation, we first multiply row 1 by 12 to get a multiple of 12 in the first column of row 1:
[tex]\begin{bmatrix}84 &-48 &96 \\-12& 7& -13\end{bmatrix}[/tex]
Next, we add row 1 to row 2 multiplied by 2 to get a 0 in column 1 of row 2:
[tex]\begin{bmatrix}84 &-48 &96 \\0& 11& 79\end{bmatrix}[/tex]
Finally, we can divide row 1 by 84 to get a 1 in row 1, column 1:
[tex]\begin{bmatrix}1 &-\frac{4}{7} &\frac{4}{7} \\0& 11& 79\end{bmatrix}[/tex]
Now we have a 1 in row 1, column 1, and the matrix is in row echelon form.

what is radius ?The radii of a circle in geometry is the separation between any two points on the circle's circumference. It is frequently used to describe how far apart two points are. One of a circle's most crucial characteristics is its radius, which is taken into account when calculating a circle's circumference, area, and diameter. The distance around a circle that passes through its centre, or its diameter, is equal to half of its radius. Other shapes like spheres, cylindrical, and cones can also be described using the radius. The radius here means the distance from the shape's centre to any point on its perimeter.
given
The following formula must be used to determine a sector's area:
A = (θ/360)[tex]\pi r^2[/tex]

5. The population, P, of a city has grown according to the mathematical model P = 50 000(1.15), where t
is the number of years since 2005.
Using a graphing tool or by hand answer the questions below.
a) What was the population of the town in 2005?
I
b) In what year will the population exceed 100 000?
Answer: Therefore, the population will exceed 100,000 in the year 2005 + 10.73 ≈ 2016.
Step-by-step explanation: a) The population of the town in 2005 is given by the formula, where t = 0 since 2005 is the starting year:
P = 50,000(1.15)^0 = 50,000
Therefore, the population of the town in 2005 was 50,000.
b) We need to find the value of t when the population P exceeds 100,000:
100,000 = 50,000(1.15)^t
Divide both sides by 50,000:
2 = 1.15^t
Take the natural logarithm of both sides:
ln 2 = ln (1.15^t)
Apply the power rule of logarithms:
ln 2 = t ln 1.15
Divide both sides by ln 1.15:
t = ln 2 / ln 1.15
Using a calculator, we get:
t ≈ 10.73
