The equation of the line parallel to y = -3x + 2 that includes the point (4,3) is y = -3x + 9

An equation is an expression that shows the relationship between two numbers and variables using mathematical operations like addition, subtraction, multiplication, exponents

The standard form of a linear function is:

y = mx + b

where m is the rate of change (slope) and b is the y intercept

Two parallel lines have the same slope

Given the line y = -3x + 2. The line parallel to y = -3x + 2 would have a slope of -3.

The line parallel to y = -3x + 2 that includes the point (4,3), is:

y - y₁ = m(x - x₁)

substituting:

y - 3 = -3(x - 4)

y = -3x + 9

The equation of the line is y = -3x + 9

The final value of the function f(t) is 2. The final value property of the Laplace transform states that the limit of f(t) as t → ∞ is equal to the value of F(s) at s = 0. In this case, F(s) = 2/s(s - 1)(s + 2), and s = 0 corresponds to t = ∞. Therefore, the final value of f(t) is 2.

The final value property of the Laplace transform can be used to find the steady-state response of a system. The steady-state response is the response of the system when the input is a constant signal. In this case, the input is a constant signal of 2, so the steady-state response is also 2.

The final value property is not applicable if the Laplace transform has a pole at s = 0. In this case, the Laplace transform would be unbounded as t → ∞, and the final value would not exist.

In the case of F(s), there is no pole at s = 0, so the final value property is applicable. Therefore, the final value of f(t) is 2.

Answer:

Value of \(p-q=1\)

Step-by-step explanation:

We need to find \(p-q\)

\(p-q=14-13\\\\=1\)

\(\huge\boxed{\sf{Hello\:there!}}\)

We are asked to evaluate p-q.

Now, if we aren't given the value of every variable, evaluating this expression is impossible. However, we do have the value of p (14) and the value of q (13)

We plug these numbers instead of the variables:

p-q

p=14

q=13

14-13

Hence, the value of the expression is 1.

The probability that their first child will be a phenotypically normal girl is 3/8 or 37.5%.

Lou Gehrig's disease, also known as amyotrophic lateral sclerosis (ALS), is typically considered as an autosomal recessive disease. This means that both copies of the gene responsible for the disease need to be inherited, one from each parent, in order for an individual to be affected by the disease.

Given that the woman and her husband are both carriers of the disease, they each have one copy of the mutated gene and one normal gene. The probability of passing on the mutated gene to their child is 1/2 for each parent since they are carriers.

To determine the probability of their first child being a phenotypically normal girl, we need to consider the inheritance pattern. Let's break it down:

Gender: The probability of having a girl is 1/2, as gender is determined by the combination of the father's sperm (containing either an X or a Y chromosome) and the mother's egg (containing an X chromosome).

Phenotypically normal: For the child to be phenotypically normal, they should inherit at least one normal gene from either parent. The probability of inheriting a normal gene from the mother is 1/2, and the same probability applies for inheriting a normal gene from the father.

Independence: The probability of having a girl and inheriting a normal gene are independent events, so we can multiply their individual probabilities to calculate the combined probability.

Therefore, the probability of having a phenotypically normal girl is:

Probability of being a girl × Probability of inheriting a normal gene

= (1/2) × (1/2)

= 1/4

However, we also need to consider the possibility of having a boy. The probability of having a phenotypically normal boy is also 1/4.

Adding the probabilities of having a phenotypically normal girl and a phenotypically normal boy, we get:

1/4 + 1/4 = 2/4 = 1/2        

Since the question specifically asks for the probability of having a phenotypically normal girl, we divide the probability of a phenotypically normal girl by the total probability of having a child:

(1/4) / (1/2) = 1/4 * 2/1 = 1/2 = 2/4 = 1/2

Therefore, the probability that their first child will be a phenotypically normal girl is 1/2 or 50%.

There are 20 players are not in 5th grades.

What is mean by Percentage?

A number or ratio that can be expressed as a fraction of 100 or a relative value indicating hundredth part of any quantity is called percentage.

To Calculate the percent of a number , divide the number by whole number and multiply by 100.

Given that;

Total players in the class = 80

And, 75% of the players in the basketball program are 5th graders.

Now.

Number of players in the basketball program are 5th graders = 75% of 80

= 75/100 x 80

= 60

Thus, Number of players are not in 5th graders = 80 - 60

                                                                          = 20

Answer:

d = 13

Step-by-step explanation:

First, the distance formula is needed:

\(d = \sqrt{(x_{2} - x_{1} )^{2} +(y_{2} - y_{1 })^{2} }\)

Next we assign the points

(2,-4) is point 1, (7,8) is point 2

\(d = \sqrt{(7 - 2 )^{2} +(8 - (-4))^{2} } \\d = \sqrt{5^{2} +12^{2} } \\d = \sqrt{25 + 144}\\ d = \sqrt{169} \\d = 13\)

Given two points (2,-4) and (7,8)

To find - The distance between given points.

We know the formula that is used to find the distance is given as

\(d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}\)

We let P = (2,-4)

and Q = (7,8)

\(x_1=2, y_1=-4\\x_2=7,y_2=8\)

on substituting we get

\(d=\sqrt{(7-2)^2+(8+4)^2}\\ d=\sqrt{(5)^2+(12)^2} \\d=\sqrt{25+144} \\d=\sqrt{169}\\ d=13\)

Hence we get the distance between (2,-4) and (7,8) is 13.

Final answer - The distance is 13.

Step-by-step explanation:

Answer:

a) x = 1.5 and x = -0.3

b) x = -8 and x = 5

Step-by-step explanation:

a)

The given equation follows the general structure: ax² + bx + c = 0.

Therefore, if a = 5, b = -6, and c = -2, you can substitute the values into the quadratic formula and solve for "x".

b)

Another way of solving polynomials is through factorization. After rearranging the equation to fit the general structure of a quadratic (as seen above), you can factor by asking yourself the question, which 2 numbers multiply to "c" (-40) and add to "b" (3)? The answers will make up your factors.

\(\huge\textsf{Hey there!}\)

\(\huge\textbf{Equation \#1. }\)

\(\mathsf{5x^2 - 6x - 2 = 0}\)

\(\huge\textbf{Use the quadratic formula to solve:}\)

\(\mathsf{x = \dfrac{-(-6)\pm \sqrt{(-6)^2 - 4(5)(-2)}}{2(5)}}\)

\(\huge\textbf{Simplify it: }\)

\(\mathsf{x = \dfrac{6 \pm \sqrt{76}}{10}}\)

\(\huge\textbf{Simplify that as well:}\)

\(\mathsf{x = \dfrac{3}{5} + \dfrac{1}{5}\sqrt{19}\ or\ x = \dfrac{3}{5} + (-\dfrac{1}{5})\sqrt{19}}\)

\(\huge\textbf{Therefore, your answer should be:}\)

\(\huge\boxed{\mathsf{x \approx 1.5 \ or\ x\approx -0.3{}\ }}\huge\checkmark\)

\(\huge\textbf{Equation \#2.}\)

\(\mathsf{x^2 + 3x = 40}\)

\(\huge\textbf{Subtract 40 to both sides:}\)

\(\mathsf{x^2 + 3x - 40 = 40 - 40}\)

\(\huge\textbf{Simplify it:}\)

\(\mathsf{x^2+ 3x - 40 = 0}\)

\(\huge\textbf{Factor the left side of the equation:}\)

\(\mathsf{(x - 5)\times (x + 8) = 0}\)

\(\mathsf{(x - 5)(x + 8) = 0}\)

yOU HAVE TO ADD ALL AND DIVIDE

The simplest ratio of squares to total shapes is 1 : 3

The ratio is defined as a relationship between two quantities, it is expressed as one divided by the other.

A square is defined as a polygon that has four sides and is a closed, two-dimensional (2D) object. A square has equal and parallel sides on all four sides.

The area of a square is equal to the squared of sides or the multiplication of two sides.

Given that there are 3 squares and 6 triangles.

To determine the simplest ratio of squares to total shapes

The number of squares = 3

The number of triangles = 6

The number of total shapes = 3 + 6 = 9

So, the simplest ratio of squares to total shapes = 3/9

The simplest ratio of squares to total shapes = 1/3

Hence, the simplest ratio of squares to total shapes is 1 : 3

These disadvantages can impact the validity and reliability of the data collected using this type of data collection method. To mitigate these issues, researchers should design the survey carefully, ensure a representative sample, and provide clear instructions to respondents.

There are several disadvantages of using the mentioned type of data collection, which could affect the quality and reliability of the data gathered.

1. Respondents may exaggerate or distort facts: It is possible that some respondents may not provide accurate information, either due to the desire to present themselves in a better light or misremembering details. This can lead to biased or inaccurate data.

2. Respondents might consider the survey to be junk mail: If the survey is distributed via mail or email, some recipients may disregard it as unwanted communication. This can result in a lower response rate and a less representative sample of the population.

3. Respondents do not have enough time to consider their answers: If the survey has a tight deadline or contains complex questions, respondents may feel rushed and not have adequate time to reflect on their responses. This can lead to hasty or incomplete answers that do not accurately capture their opinions or experiences.

4. Respondents may not represent an accurate population sample: If the survey's sample is not representative of the target population, the results may be biased and not generalizable to the broader population. It is crucial to ensure that the sample selection process is unbiased and reaches a diverse range of participants.
