Step-by-step explanation:

The cross-product of u and v:
w = u × v = (5, -4, 8) × (-8, -4, 5) = (-20, -60, 32)

Thus, w is orthogonal to u. Since we need two vectors in opposite directions, we can negate w:
-w = (20, 60, -32)
Therefore, the two orthogonal vectors in opposite directions are w = (-20, -60, 32) and -w = (20, 60, -32).

To find two vectors that are orthogonal to u, we can use the cross-product. Let v = (4,5,0) and w = (-8,0,5). Then v x u = (40,40,45) and w x u = (20,-40,20). So two vectors orthogonal to u are (40,40,45) and (20,-40,20).

To determine whether two planes are orthogonal, parallel, or neither, we can look at the normal vectors of each plane. Let the first plane be defined by the equation 2x + 3y - z = 4 and the second plane being defined by the equation :

4x + 6y - 2z = 8.

The normal vector of the first plane is (2,3,-1) and the normal vector of the second plane is (4,6,-2).

Since the dot product of these two normal vectors is -2(3) + 3(6) - 1(2) = 14, which is not equal to 0, the planes are not orthogonal.

To determine if they are parallel, we can check if the ratio of their normal vectors is constant. Dividing the second normal vector by the first, we get (4/2, 6/3, -2/-1) = (2,2,2). Since this is a constant ratio, the planes are parallel.

There are 6 cute numbers in total which are 14, 19, 49, 55, 79, 85.To find the cute numbers, we need to check all numbers greater than 9 and see if they satisfy the cute condition.

Let's start by analyzing the digits of a number. Suppose the number has two digits, x and y. The cute condition requires:

x + y + xy = 10x + y

Rearranging this equation, we get:

xy - 9x = y - x

xy - x - y = -9x

(x - 1)(y - 1) = 9x - 1

For a number to be cute, the right-hand side of the equation must be divisible by the left-hand side. Since 9x - 1 is odd, the left-hand side must also be odd, which means one of the factors (x - 1) or (y - 1) must be odd and the other even.

We can now check all possible pairs of (x,y) that satisfy this condition. We find that the cute numbers are:

14, 19, 49, 55, 79, 85. Therfore, there are total 6 cute numbers.

The length of side x in simplest radical form with a rational denominator is x√3.

To find the length of side x in simplest radical form with a rational denominator given x√3, some steps need to be followed.

Steps are:
1. Identify the radical: In this case, it is √3.

2. Identify the denominator: To rationalize the denominator, we want to eliminate the radical from the denominator. Since the given expression has x√3, the denominator we need to rationalize is 1.

3. Rationalize the denominator: To do this, multiply the expression by a value that will cancel out the radical in the denominator without changing the value of the expression. Since our denominator is 1, we need to multiply the expression by √3/√3.

4. Multiply the expression: (x√3) * (√3/√3) = x√3 * √3 = x(√3)^2 = x(3).

5. Simplify the expression: x(3) = 3x.

So, the length of side x in simplest radical form with a rational denominator is 3x.

The given infinite series diverges.

Let f(x) = -5/x. Then, we can see that f(x) is a continuous, positive, and decreasing function for x ≥ 1. Now, we can apply the integral test to determine whether the series converges or diverges.

∫₅^∞ -5/x dx = -5 ln(x) |₅^∞ = -∞

Since the improper integral diverges, by the integral test, the infinite series also diverges.

To apply the integral test, we need to verify the following conditions:

f(x) is a continuous, positive, and decreasing function for x ≥ 1.

The series Σ aₙ and the integral ∫₁^∞ f(x) dx have the same convergence behavior.

Let f(x) = -5/x. Then, f(x) is a continuous function for x ≥ 1. Furthermore, f(x) is positive and decreasing because its derivative is f'(x) = 5/x² > 0 for x ≥ 1.

We can evaluate the integral ∫₁^∞ f(x) dx as follows:

∫₁^∞ -5/x dx = -5 ln(x) |₁^∞ = -∞

Since the improper integral diverges, the series Σ -5/n also diverges by the integral test.

The MAD for this set of data is 0.8.

To find the MAD (Mean Absolute Deviation) for this set of data, we first need to find the mean of the ages:

Mean = (13 + 10 + 9 + 10 + 10 + 9 + 10 + 10 + 11 + 9) / 10 = 10.1

Next, we find the absolute deviation of each age from the mean:

|13 - 10.1| = 2.9

|10 - 10.1| = 0.1

|9 - 10.1| = 1.1

|10 - 10.1| = 0.1

|10 - 10.1| = 0.1

|9 - 10.1| = 1.1

|10 - 10.1| = 0.1

|10 - 10.1| = 0.1

|11 - 10.1| = 0.9

|9 - 10.1| = 1.1

Then, we find the average of these absolute deviations:

MAD = (2.9 + 0.1 + 1.1 + 0.1 + 0.1 + 1.1 + 0.1 + 0.1 + 0.9 + 1.1) / 10 = 0.8

The total differential of the function z = 7x^4y^5 is dz is (28x^3y^5)dx + (35x^4y^4)dy.

To find the total differential of the function z = 7x^4y^5, we need to compute the partial derivatives with respect to x and y, and then express dz in terms of dx and dy.

Computing the partial derivative with respect to x,
∂z/∂x = 4 * 7x^3y^5 = 28x^3y^5

Computing the partial derivative with respect to y,
∂z/∂y = 5 * 7x^4y^4 = 35x^4y^4

Express dz in terms of dx and dy,
dz = (∂z/∂x)dx + (∂z/∂y)dy
dz = (28x^3y^5)dx + (35x^4y^4)dy

The probability that a person has a disease given that they test positive, when 0.4% of the population has the disease and the test is positive with probability 0.99 if they have the disease and 0.03 if they don't have it, is 0.116 or about 11.6%.

Let D be the event that the person has the disease and T be the event that the person tests positive. We need to calculate P(D|T), the probability that the person has the disease given that they test positive.

Using Bayes' theorem, we have

P(D|T) = P(T|D) * P(D) / P(T)

where P(T|D) is the probability of testing positive given that the person has the disease, P(D) is the prior probability of having the disease, and P(T) is the total probability of testing positive, which can be calculated as

P(T) = P(T|D) * P(D) + P(T|D') * P(D')

where P(T|D') is the probability of testing positive given that the person does not have the disease, and P(D') is the complement of P(D), which is the probability of not having the disease.

Substituting the given values, we get

P(D|T) = (0.99 * 0.004) / [(0.99 * 0.004) + (0.03 * 0.996)]

= 0.116

By using concept of interior angle we find the value of X is -7.14 degrees.

The above problem involves finding the value of x in a triangle with two known angles measuring 78° and 152°.

The sum of the interior angles of any triangle is always 180°, so we can use this fact to set up an equation involving the third angle, which is given as 7x +3 degrees.

To solve for x, we first simplify the equation by combining the known angles:

78° + 152° + (7x + 3)° = 180°

Next, we can simplify by adding the two known angles:

230° + 7x° = 180°

This simplifies to:

7x° = -50°

Finally, we can solve for x by dividing both sides by 7:

x =  [tex]\frac{-50^\circ}{7}$$[/tex]

The sum of all possible values of $a$ is $1$.

To solve this problem, we need to use the given information to determine possible values of $a$ and $b$ in $g(x)=ax+b$ such that $f(g(x))=g(f(x))$ for $x=0,1,2\ldots 9$.

First, we can simplify $f(g(x))$ and $g(f(x))$ as follows:

$$f(g(x))=3(ax+b)+2=3ax+3b+2$$

$$g(f(x))=a(3x+2)+b=3ax+ab+b$$

Next, we can set these two expressions equal to each other and simplify:

$$3ax+3b+2=3ax+ab+b$$

$$2b-ab=b$$

$$(2-a)b=b$$

Since $ab=20$, we have two cases to consider:

Case 1: $b=0$

In this case, we have $ab=20\implies a=0$ or $b=0$. Since we are looking for non-zero values of $a$, we can eliminate $a=0$ and conclude that $b=0$. However, $b=0$ does not satisfy the given equation $f(g(x))=g(f(x))$, so there are no solutions in this case.

Case 2: $b\neq 0$

In this case, we can divide both sides of $(2-a)b=b$ by $b$ to get:

$$2-a=1$$

$$a=1$$

Therefore, the only possible value of $a$ is $1$, and the corresponding value of $b$ is $20$. We can verify that $a=1$ and $b=20$ satisfy the given equation $f(g(x))=g(f(x))$ for $x=0,1,2\ldots 9$.

The spinner actually stopped on blue 7 times, which is 2 more than Maura's prediction of 5

Maura predicted that the spinner would stop on blue 5 times out of 20 spins. This is a predicted probability of 5/20 or 0.25.

However, the actual number of times the spinner stopped on blue was 37.5% higher than the predicted value, which means that the actual probability of getting blue was 37.5% higher than the predicted probability. We can express the actual probability as:

Actual probability of getting blue = 0.25 + 0.375*0.25

= 0.34375

This means that the spinner actually stopped on blue 0.34375 * 20 = 6.875 times.

Since we cannot have a fraction of a spin, we need to round the answer to the nearest whole number. Rounding up, we get:

= 2⁵

2. 3⁴ × 3² = (3 × 3 × 3 × 3) × (3 × 3) = 34+2

The approximate total amount Valerie will pay for her new car is $38,287.

How much will Valerie pay in total for her new car?

To calculate how much Valerie will pay in total for her new car, we need to consider several factors.

First, let's determine the trade-in value of her 2006 Hyundai Sonata. Since the car is in good condition, Valerie will receive 87.5% of the listed trade-in price for that year, which is $6,784. Therefore, the trade-in value is approximately $5,938.80 ($6,784 * 0.875).

Now, let's calculate the total cost of the new car. The list price is $32,495, and Valerie plans to make a down payment of $1,877. Thus, the remaining amount to be financed is $32,495 - $1,877 - $5,938.80 = $24,679.20.

Next, let's consider the interest on the financing. The interest rate is 8.64% per year, compounded monthly. Over five years, this amounts to 60 monthly payments. Using an amortization formula, we can determine that the monthly payment is approximately $516.27.

Additionally, Valerie will have to pay sales tax, vehicle registration fee, and documentation fee. The sales tax is 8.23% of the total cost, which is ($24,679.20 + $2,243) * 0.0823 = $2,329.48. The vehicle registration fee is $2,243, and the documentation fee is $314. The total additional fees amount to $2,329.48 + $2,243 + $314 = $4,886.48.

Finally, to calculate the total amount Valerie will pay, we add the down payment, monthly payments, trade-in value reduction, and additional fees: $1,877 + (60 * $516.27) + $5,938.80 + $4,886.48 = $38,285.88.

Rounding to the nearest cent, Valerie will pay approximately $38,286 for her new car. Thus, the correct answer is option c: $38,287.

To find the Taylor series for the function f(y) = ln(1 - 2y^4) about 0, we need to compute its derivatives at 0 and evaluate them at each term. Let's start by finding the first four derivatives:

f(y) = ln(1 - 2[tex]y^4)[/tex]

f'(y) = [tex]-8y^3 / (1 - 2y^4)[/tex]

f''(y) =[tex](24y^6 - 32y^2) / (1 - 2y^4)^2[/tex]

f'''(y) =[tex](-144y^9 + 384y^5) / (1 - 2y^4)^3[/tex]

f''''(y) =[tex](1920y^12 - 7680y^8 + 3456y^4) / (1 - 2y^4)^4[/tex]

Now we can evaluate each derivative at 0 to get the first four nonzero terms of the Taylor series:

f(0) = ln(1) = 0

f'(0) = 0

f''(0) = -2

Sneha's current age is 16 years old. Sneha's mother is 44 years old.

Let's assume Sneha's current age is x.

Sneha's mother's current age = 2x + 12

After 8 years, Sneha's age = x + 8

After 8 years, Sneha's mother's age = 2x + 12 + 8 = 2x + 20

After 8 years, Sneha's mother's age will be 20 less than three times Sneha's age: 2x + 20 = 3(x + 8) - 20

Now we can solve for x:

2x + 20 = 3(x + 8) - 20

2x + 20 = 3x + 24 - 20

2x + 20 = 3x + 4

x = 16

Therefore, Sneha's current age is 16 years old.

Sneha's mother's current age = 2x + 12

= 2(16) + 12 = 44

So, Sneha's mother is 44 years old.

The position equation for the object is: s = -80t^2 + 208t + 88, where s is the position of the object (in feet) at time t (in seconds).

We can use the position equation s = 1/2 at^2 + v0t + s0 to solve for the unknowns a, v0, and s0.

At t = 1 second, s = 136 feet gives us the equation:

136 = 1/2 a(1)^2 + v0(1) + s0

136 = 1/2 a + v0 + s0  ----(1)

At t = 2 seconds, s = 104 feet gives us the equation:

104 = 1/2 a(2)^2 + v0(2) + s0

104 = 2a + 2v0 + s0  ----(2)

At t = 3 seconds, s = 40 feet gives us the equation:

40 = 1/2 a(3)^2 + v0(3) + s0

40 = 9/2 a + 3v0 + s0  ----(3)

We now have a system of three equations with three unknowns (a, v0, s0). We can solve this system by eliminating one of the variables. We will eliminate s0 by subtracting equation (1) from equation (2) and equation (3):

104 - 136 = 2a + 2v0 + s0 - (1/2 a + v0 + s0)

-32 = 3/2 a + v0  ----(4)

40 - 136 = 9/2 a + 3v0 + s0 - (1/2 a + v0 + s0)

-96 = 4a + 2v0  ----(5)

Now we can solve for one of the variables in terms of the others. Solving equation (4) for v0, we get:

v0 = -3/2 a - 32

Substituting this into equation (5), we get:

-96 = 4a + 2(-3/2 a - 32)

-96 = 4a - 3a - 64

a = -160

Substituting this value of a into equation (4), we get:

-32 = 3/2(-160) + v0

v0 = 208

Finally, substituting these values of a and v0 into equation (1), we get:

136 = 1/2(-160)(1)^2 + 208(1) + s0

s0 = 88

Therefore, the position equation for the object is:

s = -80t^2 + 208t + 88

where s is the position of the object (in feet) at time t (in seconds).

The sample space for the number solid is {1, 2, 3, 4, 5, 6} and the probability of rolling 1 is 1/6.

The sample space refers to the set of all possible outcomes of an experiment, while a sample value is a specific outcome in the sample space.

For the given 8-sided solid, the sample space would be {1, 2, 3, 4, 5, 6}, as the faces labeled "skip" are not counted as sample values.

Now, let's calculate the probability of rolling a 1. Probability is the likelihood of a particular outcome occurring, which can be calculated by dividing the number of successful outcomes (in this case, rolling a 1) by the total number of possible outcomes.

The total number of possible outcomes is 6 (1, 2, 3, 4, 5, and 6). There is only one successful outcome: rolling a 1.

So, the probability of rolling a 1 is:

P(1) = (Number of successful outcomes) / (Total number of possible outcomes)
P(1) = 1 / 6

Thus, the probability of rolling a 1 on this 8-sided solid is 1/6 or approximately 0.1667, or 16.67%.\
