Step-by-step explanation:

Answer:

see below

Step-by-step explanation:

We are here given that weight of an object having mass of 5kg is 450N .

As we know that,

Weight = mass * acceleration due to gravity (g)

So that ,

450N = g * 5kg

g = 450/5 m/s²

g = 90m/s²

Again in second case,

147N = g' * 50kg

g' = 147/50 m/s²

g' = 29.4 m/s²

since here g ≠ g'

Therefore,

mass and weight are not promotional in this case. This may be due to the fact that the acceleration due to gravitational force of each celestial object is different and weights may have been measured on different planets.

And the constant of proportionality is g ( acceleration due to the gravitational force) .

And we are done!

Answer:

2x - 6

Step-by-step explanation:

In this question, you have to simplify the expression.

Solve:

(3х - 5) - (5х + 1)

Distribute the negative sign the variables inside the parenthesis.

3x - 5 - 5x - 1

Combine like terms.

3x - 5 - 5x - 1

-2x - 5 - 1

-2x - 6

Your final answer would be -2x - 6

The solutions to the equation are x= -9 and x = 6

From the information given, we have that;

|x2 + 9x| = 6x + 54

To solve the quadratic equation, collect the like terms, we have;

x² + 9x - 6x = 54

subtract the terms

x² + 3x = 54

Put in standard form

x² + 3x - 54 = 0

Find the pair factors of -54 that add up to give 3 and substitute the values

x² + 9x - 6x - 54 = 0

group in pairs

(x² + 9x) - (6x - 54) = 0

factorize the expressions

x(x + 9) - 6(x + 9) = 0

Then, we have;

x- 6 = 0

x = 6

x + 9 = 0

The primary code we use to signal identity, according to Remland, is nonverbal communication.

Nonverbal communication refers to the transmission of messages without the use of words. It involves various forms of communication such as facial expressions, body language, gestures, posture, eye contact, and tone of voice. Remland, a researcher in the field of communication, emphasizes the significance of nonverbal cues in signaling identity.

Nonverbal cues play a crucial role in expressing our cultural, social, and personal identities. They can convey information about our emotions, attitudes, status, and affiliations. For example, the way we dress, our choice of accessories, and our body language can communicate aspects of our identity such as our gender, social group, or profession.

Nonverbal communication is particularly powerful because it often operates at an unconscious level and can convey messages that are difficult to express through words alone. These nonverbal signals can shape impressions, establish connections, and influence how others perceive and respond to us.

According to Remland, nonverbal communication is the primary code we use to signal identity. Understanding and interpreting nonverbal cues are essential for effective communication and for navigating social interactions, as they provide valuable insights into the identities and intentions of individuals.

The 95% confidence interval estimate of the mean for a random sample of size 25 is (45.07, 54.93) and for a random sample of size 16 is (43.61, 56.39).

To find the 95% confidence interval estimate of the mean for a population with an unknown mean and unknown standard deviation, we can use the formula:

CI = x ± t*(s/√n)

Where:
CI is the confidence interval
x is the sample mean
t is the t-score for the desired level of confidence
s is the sample standard deviation
n is the sample size

For a 95% confidence level and a sample size of 25, the t-score is 2.064. For a sample size of 16, the t-score is 2.131.

a) For a random sample of size 25 with a mean of 50 and a standard deviation of 12, the 95% confidence interval estimate of the mean is:

CI = 50 ± 2.064*(12/√25)
CI = 50 ± 2.064*(12/5)
CI = 50 ± 4.93
CI = (45.07, 54.93)

b) For a random sample of size 16 with a mean of 50 and a standard deviation of 12, the 95% confidence interval estimate of the mean is:

CI = 50 ± 2.131*(12/√16)
CI = 50 ± 2.131*(12/4)
CI = 50 ± 6.39
CI = (43.61, 56.39)

Therefore, the 95% confidence interval estimate of the mean for a random sample of size 25 is (45.07, 54.93) and for a random sample of size 16 is (43.61, 56.39).

Using the formulas, we have found the trigonometric ratios sin(θ) = -1/√2 and cos(θ) = 1/√2. sin(θ) = -1/√2 and cos(θ) = 1/√2 for θ = -3π/4.

Given θ=−3π/4​.

We need to find the value of sin(θ) and cos(θ).

We know that θ=−3π/4​.

Sin(θ) = sin(−3π/4)

We know that sin(−θ) = −sin(θ)

cos(−θ) = cos(θ)

So, sin(θ) = sin(−3π/4)

= −sin(3π/4)

By using the formula of sin(-θ), we get

sin(θ) = -sin(3π/4)

= -sin(π/4)

So, sin(θ) = -sin(π/4) = -1/√2

Cos(θ) = cos(−3π/4)

We know that cos(−θ) = cos(θ)

So, cos(θ) = cos(−3π/4)

By using the formula of cos(-θ), we get

cos(θ) = cos(-3π/4)

= cos(π/4)

cos(θ) = cos(π/4)

= 1/√2

Here, we are given θ = -3π/4.

Using the formulas, we have found that sin(θ) = -1/√2 and cos(θ) = 1/√2.

In conclusion, sin(θ) = -1/√2 and cos(θ) = 1/√2 for θ = -3π/4.

Answer:

7. D

8. 5,-8,34

Step-by-step explanation:

A. Parallel to the y-axis and passes through the point (3,5)

For it to be parallel to the y-axis, what this means is that it has an x-intercept and no y intercept.

So what this means is that x = 3 is our line so E is correct

B. Perpendicular to the y-axis means it is parallel to the x-axis

It means is has no x intercept and thus its x value at any point in time is zero

So the equation is y = -5

or simply y + 5 = 0 which means D is correct

C. It is parallel to the line 5x -8y + 12 = 0

Thus: 8y = 5x + 12

dividing both sides by 8

y = 5x/8 + 12/8

y = 5x/8 + 3/2

y = 5x/8 + 1.5

Comparing this with the general equation of a straight line ;

y = mx + c

where m is that slope, this means that 5/8 is the slope of the line

Mathematically if two lines are parallel, they have equal slopes.

So we can say the slope of the other line too is 5/8

Now to find the equation of the other line, we can use the point-slope method

y-y1 = m(x-x1)

where (x1,y1) in this case is (-2,3)

So we have;

y-3 = m(x-(-2))

y-3 = 5/8 (x + 2)

8(y-3) = 5(x + 2)

8y -24 = 5x + 10

5x + 10 + 24 -8y = 0

5x -8y + 34 = 0

So A, B, C = 5, -8, 34
