A homogeneous system in parametric vector form:

(x1,x2,x3) = (s,s,-0.25s)

Parametric vector Form:

Any equation expressed as a parameter is a parametric equation. The general equation y = mx + b (where m and b are parameters) of a straight line in the form of a slope intersection is an example of a parametric equation. Example: one of the variables to t(x = t). Then we can rewrite this equation as y = t²+5.

So the set of parametric equations is x = t and y=t²+5.

According to the Question:

We are to solve them in parametric form.

X₁ + 2X₂ + 12X₃ = 0     ----------------------- (1)

2X₁ + X₂ + 12X₃ = 0     ----------------------- (2)

-X₁ + X₂ = 0                  ----------------------- (3)

From equation 3 we get

x₁ = x₂

Substitute in 1 and 2 to get

3x₁ + 12x₃ = 0 and

3x₁ + 12x₃ = 0

Thus, we find these two equations are dependent.  So we can have infinite solutions in parametric form only.

No unique solution is possible

Let x₁ = x₂ = s

Since 3x₁ +12x₃ = 0

x₁ = -4x₃

Or x₃ = -0.25s

So solution in parametric form is

(x1,x2,x3) = (s,s,-0.25s) for all real values.

The dolphin traveled a total vertical distance of 17 feet during its jump. Note that the negative sign for the second and third parts of the jump indicates that the dolphin was descending during those parts.

Distance is the total amount of space traveled by an object or a person, regardless of the direction taken. It is a scalar quantity and is usually measured in units such as meters (m), kilometers (km), feet (ft), or miles (mi). Distance is different from displacement, which is the shortest distance between the starting and ending points in a particular direction.

The total vertical distance the dolphin traveled is the sum of the distances it traveled during each part of the jump:

Distance traveled during the first part of the jump (underwater to the surface): 27 feet - (-35 feet) = 62 feet

Distance traveled during the second part of the jump (out of the water to the surface): 0 feet - 27 feet = -27 feet

Distance traveled during the third part of the jump (surface to underwater): -18 feet - 0 feet = -18 feet

Total vertical distance traveled: 62 feet + (-27 feet) + (-18 feet) = 17 feet

Therefore, the dolphin traveled a total vertical distance of 17 feet during its jump. Note that the negative sign for the second and third parts of the jump indicates that the dolphin was descending during those parts.

Completing the square is a mathematical technique used to manipulate quadratic equations into a standard form that makes them easier to solve

The general form of a quadratic equation is:

ax^2 + bx + c = 0

To complete the square, you need to add and subtract (b/2a)^2 to the left side of the equation. This is because (b/2a)^2 is equal to (b/2a) times itself, which means it is a perfect square.

Here is the formula for completing the square:

ax^2 + bx + c = 0

ax^2 + bx = -c

a(x^2 + (b/a)x) = -c

a(x^2 + (b/a)x + (b/2a)^2 - (b/2a)^2) = -c

a(x + b/2a)^2 = -c + (b/2a)^2

The equation is now in the standard form:

a(x + b/2a)^2 = (4ac - b^2)/4a

By taking the square root of both sides, you can solve for x:

x = (-b +/- sqrt(b^2 - 4ac))/2a

This is the quadratic formula, which gives you the values of x that make the equation equal to zero.

The hypotheses are as follows:

Null Hypothesis (H0): The mean difference in exam scores is equal to 0. μdiff = 0

Alternative Hypothesis (Ha): The mean difference in exam scores is greater than 0. μdiff > 0

To calculate the t-statistic, we use the formula:

t = (x - μ) / (s / √n)

Where:

x is the sample mean difference (given as -1.75)

μ is the hypothesized population mean difference under the null hypothesis (0 in this case)

s is the sample standard deviation (given as 7.12)

n is the sample size (given as 35)

Substitute the given values:

t = (-1.75 - 0) / (7.12 / √35)

t ≈ -0.33071

The degrees of freedom (df) for the t-distribution.

The degrees of freedom for this test is equal to the sample size minus 1:

df = 35 - 1 = 34

The P-value is associated with the calculated t-statistic.

Since we are testing for a one-sided alternative (μdiff > 0), we need to find the area under the t-distribution curve to the right of the t-statistic.

The interquartile range (IQR) of the data in the dot plot is 3.5 players.

To find the interquartile range (IQR) of the data in the dot plot, we need to determine the values of the first quartile (Q1) and the third quartile (Q3).

The quartiles divide a dataset into four equal parts, where Q1 represents the 25th percentile and Q3 represents the 75th percentile.

Given the data points from the dot plot:

0, 1; 1, 2; 3, 3; 4, 1; 5, 1; 7, 1

First, arrange the data in ascending order:

0, 1, 1, 1, 3, 4, 5, 7

Next, find the median (Q2), which is the middle value of the data:

Median (Q2) = (3 + 4) / 2 = 3.5

Since there are 8 data points, we can calculate the position of Q1 and Q3 as follows:

Q1 position = (1/4) * (8 + 1) = 2.25

Q3 position = (3/4) * (8 + 1) = 6.75

Q1 is between the 2nd and 3rd data points: Q1 ≈ (1 + 1) / 2 = 1

Q3 is between the 6th and 7th data points: Q3 ≈ (4 + 5) / 2 = 4.5

Finally, calculate the IQR:

IQR = Q3 - Q1 = 4.5 - 1 = 3.5

Step-by-step explanation:

The solution set of the system of linear inequalities is the shaded region.

What is the system of linear inequalities?

A system of linear inequalities is a set of two or more linear inequalities that involve the same variables. Linear inequalities are mathematical statements that compare two expressions using the inequality symbols (<, >, ≤, or ≥) and indicate that one expression is less than or greater than another.

A system of linear inequalities can be represented graphically as a collection of shaded regions on a coordinate plane. The solution set of the system is the intersection of all shaded regions that satisfy all the inequalities in the system.

To find the solution set of the system of linear inequalities:

y < 3 + (1/2)x

y > 6 - (2/3)x

We can start by graphing each inequality on the same coordinate system. To do this, we can start by finding the x and y-intercepts of each inequality.

For the first inequality, y < 3 + (1/2)x, we can set x = 0 to find the y-intercept:

y < 3

So the y-intercept is at (0, 3).

Next, we can set y = 0 to find the x-intercept:

0 < 3 + (1/2)x

-3 < (1/2)x

-6 < x

So the x-intercept is at (-6, 0).

We can plot these points and draw a dashed line connecting them, since the inequality is strict (y < 3 + (1/2)x):

Attachment 1

For the second inequality, y > 6 - (2/3)x, we can set x = 0 to find the y-intercept:

y > 6

So the y-intercept is at (0, 6).

Next, we can set y = 0 to find the x-intercept:

0 > 6 - (2/3)x

6 > (2/3)x

9 > x

So the x-intercept is at (9, 0).

We can plot these points and draw a dashed line connecting them, since the inequality is strict (y > 6 - (2/3)x):

Attachment 2

Now, we need to determine which region of the graph satisfies both inequalities. We can do this by testing a point in each region. For example, we can test the point (0,0):

y < 3 + (1/2)x is true, since 0 < 3 + (1/2)(0)

y > 6 - (2/3)x is false, since 0 > 6 - (2/3)(0)

Therefore, the region below the first line but above the second line satisfies both inequalities. We can shade this region:

Attachment 3

So the solution set of the system of linear inequalities is the shaded region.

Answer: the amount of polonium remaining in the sample 1104 days later is approximately 0.12 g, and the answer is C

Step-by-step explanation:

To determine how many half-lives of polonium-210 occur in 1104 days, we can divide 1104 by the half-life of 138 days:

1104 / 138 ≈ 8

Therefore, there are approximately 8 half-lives of polonium-210 in 1104 days.

To determine how much polonium is in the sample 1104 days later, we can use the fact that the amount of polonium remaining after n half-lives is given by:

Amount remaining = initial amount × (1/2)^n

where n is the number of half-lives that have occurred.

In this case, we know the initial amount is 30 g and the number of half-lives is 8. So we can calculate the amount of polonium remaining as:

Amount remaining = 30 g × (1/2)^8 ≈ 0.117 g ≈ 0.12 g (rounded to two decimal places)

Therefore, the amount of polonium remaining in the sample 1104 days later is approximately 0.12 g, and the answer is C.
