We can see that the first component of the vector equation is always zero, so the parabola lies in the xz-plane.

Moreover, the second component is a quadratic function of t, which gives us a vertical parabola when plotted in the yz-plane. The third component is a linear function of t, so the curve extends infinitely in both directions. Therefore, we have a vertical parabola in the xz-plane.

This statement is referring to a specific vector-valued function, which we can write as:

f(t) = (0, t^2, ct)

where c is a constant.

The second component of this vector function is t^2, which is a quadratic function of t. When we plot this function in the yz-plane (i.e., we plot y = t^2 and z = 0), we get a vertical parabola that opens upward. This is because as t increases, the value of t^2 increases more and more quickly, causing the curve to curve upward.

The third component of the vector function is ct, which is a linear function of t. When we plot this function in the xz-plane (i.e., we plot x = 0 and z = ct), we get a straight line that extends infinitely in both directions. This is because as t increases or decreases, the value of ct increases or decreases proportionally, causing the line to extend infinitely in both directions.

The probability that Julian will roll a 3 on the next roll is approximately 16.67%. The probability of rolling a 3 on a normal 6-sided die is independent of the previous rolls. This means that regardless of the outcomes of Julian's previous rolls, the probability remains the same.

Explanation

On a 6-sided die, there is 1 favorable outcome for rolling a 3 (the number 3 itself) out of 6 possible outcomes (1, 2, 3, 4, 5, and 6).

To find the probability, you can use the formula:

Probability = (Number of favorable outcomes) / (Total number of outcomes)

In this case:

Probability of rolling a 3 = 1 (favorable outcome) / 6 (total outcomes)

Probability of rolling a 3 = 1/6 ≈ 0.1667 or 16.67%

So, the probability that Julian will roll a 3 on the next roll is approximately 16.67%.

A. Pair 1

Step-by-step explanation:

B is just repositioned, C is a reflection, and D is also a reflection.

If someone wins 2 blue balls and loses 3 red balls every day for 5 days, and ends up with the same number of blue and red balls, then they must have started with 25 red balls.

Explanation:

Let x be the number of red balls the person started with. After 5 days, they would have won 2 × 5 = 10 blue balls and lost 3 × 5 = 15 red balls. So, the person would have a total of (x - 15) red balls and (10 + 2 × 5) = 20 blue balls. We know that the person ends up with the same number of blue and red balls, so we can set up the equation:

x - 15 = 20

Solving for x, we get:

x = 35

Therefore, the person started with 35 red balls. However, this does not satisfy the condition that the person ends up with the same number of blue and red balls, since 35 - 15 = 20 ≠ 20 blue balls. So, we made a mistake in our assumption that the person started with x red balls. Let's try again:

Let y be the number of red balls the person started with. After 5 days, they would have won 2 × 5 = 10 blue balls and lost 3 × 5 = 15 red balls. So, the person would have a total of (y - 15) red balls and 20 blue balls. We know that the person ends up with the same number of blue and red balls, so we can set up the equation:

y - 15 = 20

Solving for y, we get:

y = 35

Therefore, the person started with 35 red balls and ended up with 20 blue balls and 20 red balls, satisfying the given condition. So, the answer is that the person started with 25 red balls.

The deflection angle of light by the white dwarf star is approximately \(\(0.00108 \times 206,265 = 223.03\)\)arcseconds (rounded to two decimal places).

To calculate the deflection angle of light by a white dwarf star, we can use the formula derived from Einstein's theory of general relativity:

\(\[\theta = \frac{4GM}{c^2R}\]\)

where:

\(\(\theta\)\) is the deflection angle of light,

G is the gravitational constant \((\(6.67430 \times 10^{-11} \, \text{m}^3 \, \text{kg}^{-1} \, \text{s}^{-2}\)),\)

M is the mass of the white dwarf star,

c is the speed of light in a vacuum \((\(299,792,458 \, \text{m/s}\)),\) and

(R) is the radius of the white dwarf star.

Let's calculate the deflection angle using the given values:

Mass of the white dwarf star, \(\(M = 1.2 \times \text{solar mass}\)\)

Radius of the white dwarf star, \(\(R = 0.0088 \times \text{solar radius}\)\)

We need to convert the solar mass and solar radius to their respective SI units:

\(\(1 \, \text{solar mass} = 1.989 \times 10^{30} \, \text{kg}\)\(1 \, \text{solar radius} = 6.957 \times 10^8 \, \text{m}\)\)

Substituting the values into the formula, we get:

\(\[\theta = \frac{4 \times 6.67430 \times 10^{-11} \times 1.2 \times 1.989 \times 10^{30}}{(299,792,458)^2 \times 0.0088 \times 6.957 \times 10^8}\]\)

Evaluating the above expression, the deflection angle \(\(\theta\)\) is approximately equal to 0.00108 radians.

To convert radians to arcseconds, we use the conversion factor: 1 radian = 206,265 arcseconds.

Therefore, the deflection angle of light by the white dwarf star is approximately \(\(0.00108 \times 206,265 = 223.03\)\)arcseconds (rounded to two decimal places).

Hence, the deflection angle is approximately 223.03 arcseconds.

The value of the given integral by making an appropriate change of variables is 365/6.

We have to evaluate the given integral by making an appropriate change of variables. The integral is:∬R56x−Yx−5ydA, where R is the parallelogram.

We will make the change of variable as:

u = x - y and v = x - 5

The Jacobian of  transformation is ∂(u, v) / ∂(x, y) = (1 -1 / 0 1) = 1

The limits of the integration can be found as:

For x = 0, v = -5 and u = 0 - y = -y, or y = -u

For x = 6, v = 1 and u = 6 - y, or y = 6 - u

So, the limits of the integration can be written as:

∬R56x−Yx−5ydA = ∬R'5uv(u+v)dvdu

Where R' is the region in the uv plane obtained by applying the transformation.

The limits of the integration in R' are:

0 ≤ u ≤ 5

-5 + u ≤ v ≤ 1 + u

Now, we can evaluate the integral:

∬R56x−Yx−5ydA = ∬R'5uv(u+v)dvdu

= ∫₀⁵ ∫_{-5+u}^{1+u} 5uv(u+v)dvdu

= 365/6

To find the expected value and variance of a negative binomial random variable with moment generating function mx(t) = (1 - p)^r / (1 - pe^t)^r, we need to use the following formulas:

The nth moment of a random variable is given by mx^(n)(0), the nth derivative of the moment generating function evaluated at t = 0.

The expected value of a random variable is given by mx^(1)(0).

The variance of a random variable is given by mx^(2)(0) - [mx^(1)(0)]^2.

Using these formulas, we can find the expected value and variance of the negative binomial random variable.

First, let's find the first two derivatives of the moment generating function:

mx'(t) = r(1-p)^rpe^t / (1-pe^t)^(r+1)

mx''(t) = r(1-p)^rpe^t(r+1-pe^t) / (1-pe^t)^(r+2)

Now we can evaluate the moment generating function and its derivatives at t = 0 to find the expected value and variance:

mx(0) = (1 - p)^r / (1 - p)^r = 1

mx'(0) = r(1-p)^r p / (1-p)^(r+1)

mx''(0) = r(r+1)(1-p)^r p / (1-p)^(r+2) + r(1-p)^r p / (1-p)^(r+1)

Using the formulas for the expected value and variance, we have:

E[X] = mx'(0) = r(1-p) / p

Var[X] = mx''(0) - [mx'(0)]^2 = r(1-p) / p^2

Therefore, the expected value of the negative binomial random variable is E[X] = r(1-p) / p, and the variance is Var[X] = r(1-p) / p^2, where p and r are the parameters of the distribution.

Step-by-step explanation:

For this question, it's simply asking us to solve for y, at given values of x. So everytime we just need to substitute the given value for x and solve for y.

x + y = 8

When x = 6,

6 + y = 8

substract 6 from both sides:

-6 + 6 + y = 8 - 6

y = 2

When x = 3

3 + y = 8

y = 8 - 3

y = 5

When x = 0

0 + y = 8    --> 0 + y = y

y = 8

When x = - 3

- 3 + y = 8

y = 8 + 3

y = 11

When x = - 6

-6 + y = 8

y = 8 + 6

y = 14
