y₂ = m(x₂ - x₁) + y₁ is an equivalent equation solved for y₂, using the concept of linear equation.
What is a linear equation?A linear equation has the following standard form: ax + by + c = 0.
Here, variables x and y and constants a, b, and c are used.
Also, a ≠ 0, and b ≠ 0.
For linear equations, the slope-intercept formula is: y=mx+b
Where m stands for the line's slope and b represents the y-intercept.
The three types of linear equations are point-slope, slope-intercept, and standard form.
When an algebraic equation is graphed, it always produces a straight line since each term has an exponent of 1 or 0. This is known as linear equations.
given that,
The slope m, of a linear equation can be found using the formula:
m = (y₂-y₁)/(x₂-x₁)
m(x₂ - x₁) = y₂ - y₁
m(x₂ - x₁) + y₁ = y₂
y₂ = m(x₂ - x₁) + y₁
hence, y₂ = m(x₂ - x₁) + y₁ is an equivalent equation solved for y₂.

Answers
True. Hexadecimal numbers are written using the base 16 number system, where digits range from 0 to 9 and A to F. They are commonly used in computer systems for concise representation and easy conversion to binary.
In the hexadecimal number system, there are 16 symbols used to represent values, namely 0-9 and A-F. Each digit in a hexadecimal number represents a multiple of a power of 16.
The symbols 0-9 represent the values 0-9, respectively. The symbols A-F represent the values 10-15, respectively, where A represents 10, B represents 11, C represents 12, D represents 13, E represents 14, and F represents 15.
For example, the hexadecimal number "3F" represents the value (3 * 16^1) + (15 * 16^0) = 48 + 15 = 63 in decimal.
Similarly, the hexadecimal number "AB8" represents the value (10 * 16^2) + (11 * 16^1) + (8 * 16^0) = 2560 + 176 + 8 = 2744 in decimal.
Hexadecimal numbers are commonly used in computer systems, as they provide a convenient way to represent large binary numbers concisely. Each hexadecimal digit corresponds to a four-bit binary number, allowing for easy conversion between binary and hexadecimal representations.

Answers
Based on the given information, the question is asking about the apparent relationship between two variables: study hours and test score. The correct answer is c.
Test score tends to increase as the number of study hours increases. This suggests a positive correlation between the two variables, meaning that as one variable (study hours) increases, the other variable (test score) also tends to increase.
The apparent relationship between the two variables under consideration, which are study hours and test score, can be described as follows:
Your answer: c. Test score tends to increase as the number of study hours increases.
This is because, generally, the more time a person spends studying, the better their understanding of the material, which often leads to a higher test score.

Write the standard form for a parabola that has the following x intercepts: (-4, 0) and (7, 0).
Answers
Answer:
y = x² - 3x - 28
Step-by-step explanation:
given a parabola with x- intercepts x = a and x = b , then
(x - a) and (x - b) are the corresponding factors and the equation is the product of its factors
y = (x - a)(x - b)
here the x- intercepts are x = - 4 and x = 7 , then the factors are
(x - (- 4)) and (x - 7) , that is (x + 4) and (x - 7) , then
y = (x + 4)(x - 7) ← expand using FOIL , then
y = x² - 3x - 28 ← in standard form
In a simple random sample of size 64, there were 38 Individuals in the category of interest. Compute the sample proportion p. Round the answer to at least three decimal places The sample proportion is
Answers
the sample proportion is approximately 0.594.To compute the sample proportion, we need to divide the number of individuals in the category of interest by the total sample size.
In this case, population there were 38 individuals in the category of interest, and the sample size was 64. Therefore, the sample proportion is:
p = 38/64
p = 0.59375
Rounding to three decimal places, we get:
p ≈ 0.594
So, the sample proportion is approximately 0.594.
The sample proportion is an estimate of the population proportion, which tells us the proportion of individuals in the entire population that belong to the category of interest. The larger the sample size, the more accurate the estimate is likely to be. We can use the sample proportion to construct a confidence interval for the population proportion or to test hypotheses about the population proportion.

Solve the initial value problem. \[ t^{2} y^{\prime \prime}-t y^{\prime}+2 y=0, \quad y(1)=1, y^{\prime}(1)=2 \]
Answers
The particular solution that satisfies the initial conditions is:
\(y(t) = (1/2 + 1/4i) * t^(1+i) + (1/2 - 1/4i) * t^(1-i)\)
To solve the initial value problem, we can use the method of undetermined coefficients.
Let's assume a solution of the form \(y(t) = t^n,\) where n is a constant to be determined.
First, we find the derivatives of y(t):
\(y'(t) = nt^(n-1)\\y''(t) = n(n-1)t^(n-2)\)
Substituting these derivatives into the given differential equation, we have:
\(t^2 * y''(t) - t * y'(t) + 2y(t) = 0\)
Replacing y(t) and its derivatives with the corresponding expressions:
\(t^2 * [n(n-1)t^(n-2)] - t * [nt^(n-1)] + 2t^n = 0\)
Simplifying the equation:
\(n(n-1)t^n - n(t^n) + 2t^n = 0\)
Combining like terms:
\(n(n-1)t^n - nt^n + 2t^n = 0\)
Now, we can factor out t^n:
\(t^n [n(n-1) - n + 2] = 0\)
For this equation to hold for all t, the expression inside the brackets must be equal to zero:
n(n-1) - n + 2 = 0
Expanding and rearranging the equation:
\(n^2 - n - n + 2 = 0\)
\(n^2 - 2n + 2 = 0\)
Using the quadratic formula, we find the roots of this equation:
n = (2 ± sqrt(\((-2)^2\) - 4*1*2)) / (2*1)
n = (2 ± sqrt(4 - 8)) / 2
n = (2 ± sqrt(-4)) / 2
Since the discriminant is negative, there are no real roots for n. However, we can have complex roots. Let's express n in terms of the imaginary unit, i:
n = (2 ± 2i) / 2
n = 1 ± i
So, the general solution for y(t) is given by:
\(y(t) = c1 * t^(1+i) + c2 * t^(1-i)\)
To find the particular solution that satisfies the initial conditions, we substitute y(1) = 1 and y'(1) = 2 into the general solution.
\(y(1) = c1 * 1^(1+i) + c2 * 1^(1-i)\)
1 = c1 + c2
Differentiating y(t) with respect to t:
\(y'(t) = (1+i) * c1 * t^i + (1-i) * c2 * t^(-i)\)
Substituting t = 1 and y'(1) = 2:
2 = (1+i) * c1 + (1-i) * c2
We now have a system of equations:
c1 + c2 = 1
(1+i) * c1 + (1-i) * c2 = 2
Solving this system of equations will give us the values of c1 and c2, which will determine the particular solution.
By solving the system of equations, we find:
c1 = 1/2 + 1/4i
c2 = 1/2 - 1/4i
Therefore, the particular solution that satisfies the initial conditions is:
\(y(t) = (1/2 + 1/4i) * t^(1+i) + (1/2 - 1/4i) * t^(1-i)\)
