Answer:
65 square units
Step-by-step explanation:
Assuming point O refers to the origin, the segment OA has slope ...
m = Δy/Δx = 5/1 = 5
Then the slope of the perpendicular line AP will be the negative reciprocal of this, -1/5.
The x-intercept of the line through (1, 5) with slope -1/5 can be found by setting y=0 in the point-slope equation for that line:
y -k = m(x -h) . . . . . . line with slope m through point (h, k)
0 -5 = (-1/5)(x -1)
25 = x -1 . . . . . . . multiply by -5
x = 26 . . . . . . . add 1
This means ΔOAP has a base length (OP) of 26 units and an altitude of 5 units. Its area is given by the formula ...
A = 1/2bh
A = 1/2(26)(5) = 65 . . . . square units
Triangle OAP has an area of 65 square units.

Solve the inequality. Graph the solution, if possible.
24. |m|greater than or equal to 10
We can use inequality, 24. |m| greater than or equal to 10 then the possible to value is = |14|.
What is Inequality :A statement of an order relationship—greater than, greater than or equal to, less than, or less than or equal to—between two numbers or algebraic expressions.
Based on the given conditions, formulate,
24. |m| greater than or equal to 10
So, we can write,
24 + m ≥ 10
m ≥ 10 - 24
We can sum or difference,
m ≥ -14
Then,
|m| ≥ |-14|
Hence,
|m| ≥ |14|

A cell site is a site where electronic communications equipment is placed in a cellular network for the use of mobile phones:
y = 336.01/1 + 29.39e^-0.256
Use the model to find the numbers of cell sites in the years 1998, 2008, and 2015.
The approximate numbers of cell sites for the years 1998, 2008, and 2015 based on the given model.
To find the number of cell sites in the years 1998, 2008, and 2015 using the given model equation:
y = 336.01/(1 + 29.39e^(-0.256))
We substitute the respective years into the equation and calculate the value of y.
For the year 1998:
Substituting t = 1998 into the equation:
y = 336.01/(1 + 29.39e^(-0.256*1998))
For the year 2008:
Substituting t = 2008 into the equation:
y = 336.01/(1 + 29.39e^(-0.256*2008))
For the year 2015:
Substituting t = 2015 into the equation:
y = 336.01/(1 + 29.39e^(-0.256*2015))
To find the actual numerical values, we need to evaluate these expressions using a calculator or a computer program that can handle exponentiation and arithmetic calculations.
Please note that it is important to follow the correct order of operations when evaluating the exponent term, particularly the negative sign and the multiplication. The exponent term should be calculated first, and then the result should be multiplied by -0.256.
By substituting the respective years into the equation and evaluating the expression, you will obtain the approximate numbers of cell sites for the years 1998, 2008, and 2015 based on the given model.

Let the random variable X be normally distributed with the mean ? and standard deviation ?. Which of the following statements is correct?
A. All of the given statements are correct. B. If the random variable X is normally distributed with parameters ? and ?, then a large ? implies that a value of X far from ? may well be observed, whereas such a value is quite unlikely when ? is small. C. The statement that the random variable X is normally distributed with parameters ? and ? is often abbreviated X ~ N(?, ?). D. If the random variable X is normally distributed with parameters ? and ?, then E(X) = ? and Var(X) = ?^2. E. The graph of any normal probability density function is symmetric about the mean and bell-shaped, so the center of the bell (point of symmetry) is both the mean of the distribution and the median.
Given the random variable X that is normally distributed with the mean μ and standard deviation σ.
The correct statement among the following options is D.
If the random variable X is normally distributed with parameters μ and σ, then E(X) = μ
and Var(X) = σ².
The normal distribution is the most widely recognized continuous probability distribution, and it is used to represent a variety of real-world phenomena.
A typical distribution, also known as a Gaussian distribution, is characterized by two parameters:
its mean (μ) and its standard deviation (σ).
The mean (μ) of any normal probability distribution represents the middle of the bell curve, and its standard deviation (σ) reflects the degree of data deviation from the mean (μ).
So, any normal probability density function is symmetric about the mean and bell-shaped, and the middle of the bell is both the mean of the distribution and the median.
Therefore, if the random variable X is normally distributed with parameters μ and σ, then E(X) = μ
and Var(X) = σ².

The greatest common factor (GCF) of the terms in the polynomial \(8x^4 - 4x^3 -18x^2\) is \(2x^2.\)
To find the greatest common factor (GCF) of the terms in the polynomial \(8x^4 - 4x^3 - 18x^2\), we need to identify the largest expression that divides evenly into each term.
Let's break down each term individually:
\(8x^4\) can be factored as 2 × 2 × 2 × x × x × x × x
\(-4x^3\) can be factored as -1 × 2 × 2 × x × x × x
\(-18x^2\) can be factored as -1 × 2 × 3 × 3 × x × x
Now, let's look for the common factors among these terms:
The common factors for all the terms are 2 and \(x^2\).
Therefore, the greatest common factor (GCF) of the terms in the polynomial \(8x^4 - 4x^3 -18x^2\) is \(2x^2.\)

For the following exercises, write a formula for the function g that results when the graph of a given toolkit function is transformed as described.
63. The graph of f(x)=∣x∣ is reflected over the y-axis and horizontally compressed by a factor of 1/4.
The formula for the function g that results when the graph of a given toolkit function is transformed as described is g(x) = 4|x| for the given transformation of reflection over the y-axis and horizontal compression by a factor of 1/4.
We know that the toolkit function is f(x)=|x|. We are reflecting the given function over the y-axis, which means all the points will change the sign of their x-coordinates. This is the transformation of the form f(-x).So, the function after reflection over the y-axis is f(-x) = |-x| = |x|. Now, we are horizontally compressing the function by a factor of 1/4. The transformation of the form f[bx] compresses the graph horizontally by a factor of 1/b. So, the compressed function is g(x) = f(4x) = |4x| = 4|x|. Therefore, the formula for the function g that results when the graph of a given toolkit function is transformed as described is g(x) = 4|x| for the given transformation of reflection over the y-axis and horizontally compressing by a factor of 1/4.

Answer:
y= 3x -5
Step-by-step explanation:
The equation of a line can be written in the slope- intercept form, y= mx +c (where m is the slope and c is the y- intercept).
Given that the slope is 3, m= 3. Substitute m= 3 into the equation.
y= 3x +c
To find the value of c, substitute a pair of coordinates into the equation.
When x= 1, y= -2,
-2= 3(1) +c
-2= 3 +c
c= -2 -3
c= -5
Thus the equation if the line is y= 3x -5.
What is the volume of the composite figure?
Answer:
1428 in³
Step-by-step explanation:
To find the volume of this figure, we will need to use two formulas. The volume of a Rectangular Prism \((A=l*w*h)\) and volume of a triangular prism.
\((A=\frac{1}{2} (b*h )\)
If we look at the Rectangular Prism, we can find that l = 17, w = 8, and h = 5. Multiply these to find the volume:
17 × 8 × 5 = 680 in³.
Solving for the triangular prism gives us:
A = 1/2 (11 × 8 × 17)
A = 748.
Add these two volumes to find the volume of the composite figure:
748 + 680 = 1428 in³

When solving proportions, we set the cross products equal, and then we solve for the unknown variable.
When solving proportions, we set the cross products equal to each other and then proceed to solve for the unknown variable. A proportion is an equation that states that two ratios or fractions are equal. To solve a proportion, we first identify the two ratios involved and set their cross-products equal.
For example, consider the proportion: a/b = c/d
To solve for the unknown variable, we set the cross products (a * d) and (b * c) equal:
a * d = b * c
This equation allows us to find the value of the unknown variable by manipulating the equation through multiplication or division to isolate the variable on one side of the equation.
By setting the cross products equal, we essentially establish an equality between the two ratios, indicating that the fractions on either side of the proportion are equivalent. Solving for the unknown variable allows us to determine its value based on the relationship between the given ratios.

The length of the hypotenuse of a 45 90 45 triangle whose leg measures 9 in is 12.73 in.
The Pythagorean theorem states that in a right triangle, the square of the length of the hypotenuse (c) is equal to the sum of the square of the length of the other two sides (a and b).
In this case, a = b = 9 in, so:
c2 = 92 + 92
c2 = 81 + 81
c2 = 162
c = √162
c = 12.73 in
