Answer:

The solution is (2,2)

Answer:

2,2

Step-by-step explanation:

To show that w = u × v and v = w × u, we need to demonstrate that the cross product of vectors u and v yields the same result as the cross product of vectors w and u.

Given that u = v × w, let's calculate the cross product of w and u:

w × u = (u × v) × u

Since the cross product is not associative, we need to use the vector triple product identity:

w × u = u × (v × u) - (u · u) v

Since u is orthogonal to v, the dot product (u · v) is zero. Therefore, we can simplify the equation:

w × u = u × (v × u)

Next, let's calculate the cross product of v and u:

v × u = (u × v) × v

Using the vector triple product identity:

v × u = v × (u × v) + (v · v) u

Again, since u is orthogonal to v, the dot product (v · v) is zero:

v × u = v × (u × v)

Thus, we have shown that w = u × v and v = w × u, indicating that the cross products are equivalent in both directions.

In summary, when u, v, and w are orthogonal unit vectors, the cross product of u and v yields the same result as the cross product of w and u, as well as the cross product of v and w.

Step-by-step explanation:

The range of scores that Steve needs to get an average of 70 to 79 is 66 to 87 Points.

To find the range of scores that Steve needs to have to stay in the 70 to 79 range we first need to define the variables that we need to find.

Let x = Score that Steve needs

Since the exam is worth 3 exams, we will then use 3x to denote the weight of the final exam.

Now we need to add all the other exams and divide it by the number of exams.

\(\frac{3x + 70+77+71+71}{7} = 70\)

3x + 292 = 7 *70

3x = 490 -292

3x = 198

\(\frac{3x}{3} =\frac{198}{3}\)

x = 66

Now let's look for the score that Steve needs to get to a 79 average.

\(\frac{3x + 70+77+71+71}{7} = 79\)

3x + 292 = 7 * 79

3x + 292 = 553

3x = 553 - 292

3x = 261

x = 87

So the range of scores is 66 to 87 Points.

-x+6 ≤ 5

We can simplify the answer by subtracting six on both sides and then dividing by -1 on both sides.

Solving for the matrix X in the equation AX = B involves using matrix algebra and the concept of matrix inverse, and the solution depends on whether A is invertible or not.

To solve for the matrix X in the equation AX = B, we can use matrix algebra and the concept of matrix inverse.

If A is an invertible matrix, we can multiply both sides of the equation AX = B by A^(-1) (the inverse of A) to get:

X = A^(-1)B

This formula gives us the unique solution to the equation AX = B.

However, if A is not invertible, the equation AX = B may not have a unique solution, or it may not have a solution at all. In this case, we may need to use other techniques such as Gaussian elimination to solve the equation.

matrix multiplication is not commutative, so in general, we cannot assume that XA = B has the same solution as AX = B. In fact, if A is not invertible, then the equation XA = B may not have a solution at all.

The drama club is holding auditions for five different parts in a one act play. If 9 people audition, how many ways can the roles be assigned?

a. 362,880

b. 15,120

c. 126

d. 120

Answer:

b. 15,120

Step-by-step explanation:

In other to solve the question above, we would use the formula for permutation.

This is because when assigning 5 DIFFERENT roles to 9 people, the order of assigning the roles is important. The formula for permutation, is used when order is involved.

Permutation (n, r) = nPr = n!/(n - r)!

In the above question,

n = 9 people

r = 5 different parts

9P5 = 9!/(9 - 5)!

= 9!/4! = 9×8×7×6×5×4×3×2×1/ 4×3×2×1

= 362880/ 24

= 15,120

Therefore, the number of ways that the roles can be assigned is 15,120 ways

If 6 boys and 4 girls get off the bus at the next bus stop, the ratio of girls to total students will be 14/27.

There are 22 boys and 32 girls on a school bus, 6 boys and 4 girls get off the bus at the next bus stop.

Total boys = 22

Total girls = 32

Total Student = Total boys + Total girls

Total Student = 22 + 32

Total Student = 54

The girls gets off = 4

Now remaining girls in bus = Total girls - The girls gets off

Now remaining girls in bus = 32 - 4

Now remaining girls in bus = 28

The ratio of girls to total students = Now remaining girls in bus/Total Students

The ratio of girls to total students = 28/54

The ratio of girls to total students = 14/27

The lifting force if the speed is 220 miles per hour is F' = 708.53 N.

The force of light, or simply light, is the sum of all forces on an object that cause the object to move perpendicular to the direction of flow.

The most common type of lift is the wing lift. But there are many other common uses, such as propellers on airplanes and ships, rotors on helicopters, fan blades, sails on sailboats, and wind turbines.

We have,

The lifting force, F, exerted on an airplane wing varies jointly as the area, A, of the wing's surface and the square of the plane's velocity, v. It, means that,

\(F=kAv^{2}\)

Where

k is constant

If, A = 190 Ft², v = 220 mph, F = 950 pounds

Now, find k first from the above data. So,

    \(k=\frac{F}{Av^{2} }\)

⇒ \(k=\frac{950}{190* (220)^2}\)

⇒ k = 0.0001033

It is required to find the lifting force on the wing if the plane slows down to 190 miles per hour.

Let F' is a new force. So,

    F' = 0.0001033 × 190 × (190)²

⇒ F' = 708.53 pounds.

So, the lifting force is 708.53 pounds if the plane slows down to 190 miles per hour.

The function m(t) determines Tim's vertical distance above the horizontal diameter of the Ferris wheel, measured in radii, in terms of the number of seconds elapsed, t, Tim started to rotate from the 3 o'clock position.

The Ferris wheel can be visualized as a circle, with the horizontal diameter representing the ground level. As Tim rotates on the Ferris wheel, his vertical distance above the ground level changes.

To determine Tim's vertical distance in terms of time, we can use a sine function to model the motion. The sine function oscillates between -1 and 1, with a period of 2π radians. If we consider the starting point at the 3 o'clock position as 0 radians, the equation for the function m(t) can be written as m(t) = sin(t).

In this equation, t represents the number of seconds elapsed since Tim started rotating from the 3 o'clock position. As t increases, Tim's vertical distance above the horizontal diameter will vary sinusoidally. The values of m(t) will range between -1 and 1, with 0 representing the horizontal diameter.

By using the sine function, we can determine Tim's vertical position at any given time t, measured in radii.
