The statement that is true is:

Statements 1 and 3

Let's examine each statement individually:

If n is a multiple of 8, then n is a multiple of 4. This statement is true because every number that is divisible by 8 is also divisible by 4. Since 8 is a multiple of 4, any multiple of 8 will have factors of both 8 and 4. If n is a multiple of 18, then n is a multiple of 2.

This statement is also true. Any number that is divisible by 18 is also divisible by 2 because 18 contains a factor of 2. Every multiple of 18 will have at least one factor of 2.

Statement 2 is not true. If n is a multiple of 18, then n is a multiple of 9.

This statement is false because there are numbers that are multiples of 18 but not multiples of 9. For example, 18 itself is a multiple of 18 but not a multiple of 9, as 18 divided by 9 is equal to 2.

To get the slope of the line tangent to the particle's path at the point where t=3, we need to find the derivative of y with respect to x and the value of k is 1.

A tangent is a line that touches the curve or a circle at a point. The point at which the tangent line and the curve meets is called the point of tangency. Steps here:
Step:1 y = kt^2
x = ln(t+1)
Step:2 Using the chain rule, we can find dy/dx as follows: dy/dt = 2kt
dx/dt = 1/(t+1)
dy/dx = (dy/dt)/(dx/dt) = 2kt/(1/(t+1)) = 2k(t+1)
Step:3. Now we can use the fact that the slope of the tangent line at t=3 is 8:
dy/dx = 2k(3+1) = 8

answer:

y=2x+6

solution:

Alright, since the line is PARALLEL, the slope will remain the same. let call the # we will add to that b (like the 5 in y=2x+5).

so the formula will be y=2x+b

to find be, we will plug in one of the ordered pairs

6=2(0)+b

6=0+b

b=6

So, our equation is y=2x+6

to check:

(-3,0)

0=2(-3)+6

0=-6+6

0=0

Answer:

y = 2x + 6

Step-by-step explanation:

The equation for this is y=mx+b, m being for slope and b being the y-intercept.

The first and easiest way to figure out this first is by finding the slope. Now because you have the information that it needs to be parallel, it's very fast and simple. Parallel means that it has the same slope and the lines will never cross each other. So, since the slope for this is 2, the new line you will be making will also have a slope of 2.

EXTRA NOTE- if it were perpendicular, you'd want to do the opposite reciprocal. Instead of being 2, it'd be -1/2, but luckily we're just dealing with parallel.

Now we need to find what the y-intercept is. Since math basically has a formula for everything, you will be using y-y(1)= m(x-x(1)). Now that looks slightly confusing, but basically you will just plug your y value into the y(1) and x coordinate into x(1) to simplify into slope intercept form (don't forget your slope!). It's always easier to use positive numbers for this, so I'll be using the coordinates (0, 6) and plug it in.

REMEMBER- coordinates are (x, y). Don't get it mixed up!

1. Write out your equation: y - 6 = 2 ( x - 0 )

2. Distribute: y - 6 = 2x - 0

3. Add 6 to the other side to get into your slope intercept form:  y = 2x + 6

And that's how you get your line. Hope this helped and made at least some sense. :)

The largest possible volume of the box, given the constraint of 1700 square centimeters of material, is approximately 18709.5437 cubic centimeters. This volume is achieved by making the base of the box with a side length of approximately 23.2379 centimeters.

To determine the largest possible volume of the box with a square base and an open top, we need to maximize the volume.

Let's assume that the length of each side of the square base is 's' centimeters, and the height of the box is 'h' centimeters.

The volume of a box with a square base is given by V = s² * h.

We have that the total surface area of the material available is 1700 square centimeters. The surface area of the box consists of the base and four sides, so we have:

Surface area = s²+ 4sh

Since the top is open, we don't need any material for it.

Now, we can rewrite the surface area equation as:

s² + 4sh = 1700

To maximize the volume, we can solve this equation for 'h' in terms of 's' and substitute it into the volume equation:

h = (1700 - s²) / (4s)

V = s² * [(1700 - s²) / (4s)

Simplifying further:

V = (1/4)(1700s - s³)

To determine the largest possible volume, we need to maximize this function. We can take the derivative of V with respect to s, set it to zero, and solve for 's'.

dV/ds = 1700/4 - (3/4)s²

Setting dV/ds = 0, we have:

1700/4 - (3/4)s² = 0

Simplifying further:

1700 = 3s²

s² = 1700/3

s ≈ 23.2379 cm

Substituting this value of 's' into the volume equation, we get:

V ≈ (1/4)(1700 * 23.2379 - (23.2379)^3)

V ≈ 18709.5437 cubic centimeters

Therefore, the largest possible volume of the box is approximately 18709.5437 cubic centimeters.

Slope of the line is 2/3

Step-by-step explanation:

Given the slope-intercept equation

2x - 3y = 5

The standard form of the slope-intercept equation is

y = mx + b

where m = slope of the line

b = intercept of the y-axis

Rearrange the above equation

2x - 3y = 5

-3y = 5 - 2x

-3y = -2x + 5

Divide through by -3

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

y = 2x/3 - 5/3

Hence, the slope of the line is 2/3

350+x/5=90

350+x=90 * 5

350+x=450

x=450-350

x=100

The score on the last test in order to have a test average of 90 is 100.

Given that, Rob's first four test scores are 80, 85, 100 and 85.

We need to find the score on the last test in order to have a test average of 90.

By definition, an average is the arithmetic mean of the sum of all the values divided by the total number of values in a given set. An average is calculated for those sets of values which are more or less the same. The term average describes the numeric value that represents a large amount of data. An average can be derived by calculating the ratio of the sum of all the values to the number of units or values.

Let the score on the last test be x.

Now, average=(80+85+100+85+x)/5 =90

⇒350+x=450

⇒x=100

Therefore, the score on the last test in order to have a test average of 90 is 100.

Recovered memory in CSA refers to the new development of abusive memories. Repressed memory is when the patient believes the CSA occurred, even though they have no specific memory of the event.

Recovered memory:

The term "recovered memory" implies that at some point the memory must become inaccessible to conscious awareness (as opposed to "continuous memory"). Although the term is not ideal, it is clear that people often fail to report important events, such as known hospitalizations (Loftus, 1993). In 1995, the debate over reclaiming memory was near its most violent climax. Hundreds of people have recovered memories of child sexual abuse (CSA), and sometimes in therapy it is thought that repressed or dissociative memories need to be recovered for a person to 'heal'.

Repressed Memory:

Repressed memory is a purported psychiatric phenomenon involving the inability to recall autobiographical information, usually traumatic or stressful. The concept has its origins in psychoanalytic theory, where repression is understood as a defense mechanism that keeps painful experiences and unacceptable impulses out of awareness. Repressed memory is a controversial concept, especially in a legal context, where it is used to unjustly and inaccurately accuse individuals, causing significant harm. Meanwhile, a working group from the American Psychological Association has stated that while "most people who were sexually abused in childhood remember some or all of what happened to them, it is possible to remember long-forgotten abuses.
