Step-by-step explanatibecause its congruent to a suplementary angle

The vector v+w has a magnitude of 2√2 and its direction is along the positive x-axis.

What is meant by vector?

A vector is a quantity that has both magnitude and direction. It is represented as an arrow with its length representing the magnitude and its direction representing the direction of the quantity.

What is meant by the x-axis?

The x-axis is the horizontal line on a coordinate plane that is used as a reference for plotting and describing the positions of points in two-dimensional space. It is often referred to as the "horizontal axis" or the "abscissa".

According to the given information

Here the vector v has a magnitude of 2 and a direction of 45° so the components of vector v are:

v_x = 2 cos 45° = √2

v_y = 2 sin 45° = √2

Vector w has a magnitude of 2 and a direction of 45° South of East. This means that the angle between vector w and the positive x-axis is 45°, and the angle between vector w and the negative y-axis is 45°. Therefore, the components of vector w are:

w_x = 2 cos 45° = √2

w_y = -2 sin 45° = -√2

Now we can add the components of vectors v and w to find the components of the vector v+w:

(v+w)_x = v_x + w_x = √2 + √2 = 2√2

(v+w)_y = v_y + w_y = √2 - √2 = 0

In this case, we are to determine the probability of selecting two even numbers. This can be solved as follows:There are six even numbers: {2, 4, 6, 8, 10, 12}.We can use the concept of conditional probability since the first event affects the probability of the second event. This can be expressed as follows:

In this case, P(A) represents the probability of selecting an even number, and P(B|A) represents the probability of selecting an even number given that the first card selected was even. P(A) = 6/12 = 1/2 (there are six even numbers and twelve cards in total)P(B|A) = 5/11 (there are five even numbers left in the box after the first even number is selected, and eleven cards are left in total).

The probability of selecting two even numbers can be found by multiplying these probabilities: P(A) x P(B|A) = (1/2) x (5/11) = 5/22Therefore, the probability of selecting two even numbers is 5/22.Answer: 5/22

Anya her distance back to camp and the bearing angle from her starting point is 4.78 km North 26.3° West.

Define direction ?

Direction gives the information about the way towards which an object moves or tends.

The angle formed by the 2 km and 3 km is the supplement of the 35 ° angle west of north;

  180°- 35° = 145°

We know that the length of two sides and one angle.

The opposite side know angle is the direct distance between the starting and ending points.

Using the law of cosines.

\(a^{2} = b^{2} + c^{2} - 2bc (cosA)\)

\(a^{2} = 2^{2} + 3^{2} - 2(2)(3)(cos 145)\)

\(a^{2} = 4 + 9 - 12 (-0.8192)\)

\(a^{2} = 22.83\)

a = 4.78 km

To determine the bearing from the starting point , we must determine the angle between the first leg and the direct path.

Using the law of sines

\(\frac{4.78}{sin(145)} = \frac{3}{sin C}\) sin(145°)

4.78 sin C = 3 sin 145°

sin C = \(\frac{3 sin (145^ 0)}{4.78}\)

sin C = 0.4438

C = 26.3°

Therefore, the distance and bearing of the end point from the starting point is 4.78 km North 26.3 ° West.

Question: find the x- or t intercepts of the polynomial function:

c(t)=2(t-4)(t+1)(t-6)​.

Solution:

the t-intercept (zeros of the function) of the given polynomial function occurs when c (t) = 0, that is when:

this can only happen when any of the factors of the polynomial are zero:

t-4 = 0, that is when t = 4

t + 1 = 0 , that is when t = -1

and

t-6 = 0, that is when t = 6.

then, we can conclude that the t-intercept (zeros of the function) of the given polynomial are

t = 4, t = -1 and t = 6.

The solutions to the equation \($x^2 = 6 - x$\) are \($x = -3$\) and \(x = 2$.\)

What is square of a number?

The square of a number is the result of multiplying the number by itself. In mathematical notation, the square of a number "\(x\)" is written as "\(x^2\)".

Let's call the number we are looking for "x".

According to the problem statement, we have:

\($$x^2 = 6 - x$$\)

We can rearrange this equation to get:

\($$x^2 + x - 6 = 0$$\)

Now, we can factor the left-hand side of this equation:

\($$(x + 3)(x - 2) = 0$$\)

So, either \($x + 3 = 0$\) or \(x - 2 = 0$.\) Solving for x in each case gives us:

\($$x = -3 \text{ or } x = 2$$\)

Therefore, the solutions to the equation \($x^2 = 6 - x$\) are \($x = -3$\) and \(x = 2$.\)

1. Kennedy should go to Mapel Avenue park for (coordinate 1) because the distance is 2 units away from her house

2. Kennedy should go to Mapel Avenue park for (coordinate 2) because it is 2.25 unites away.

To calculate distance for the parks, we use the formula

Distance = √((x2 - x1)² + (y2 - y1)²)

For example, if we input the coordinate for coordinate 2, it would be

1: √(2 - 2)² + √(1.5 - (-3/4))² = 2.25

2: √(-1/2 - 2)² + √(-3/4 - (-3/4))² = 2.5

Step-by-step explanation:

The formula for determining distance is expressed as

Distance = speed × time

From the information given,

Speed of boat = 10 miles per hour

It means that the distance that the boat covered after t hours is 10 × t = 10t miles

Since the boat is 100 miles away from the marina and it is sailing directly towards it, then the equation for the distance of the boat from the marina after t hours is

Distance = 100 - 10t

6x 2 = 12 is your answer your welcome

Answer: Explain why     2 + 3(x � 2) = 5x � 10  (*)  is not true identity.

It is because the left part is

   2 + 3x - 6 = 3x - 4,

while the right side is 5x - 10.

The left side expression differs from that of the right side.

Therefore, (*) is not an identity.

We even can go further and write a hypothetical equation

3x - 4 = 5x - 10

which implies

2x = 6  and    then   x = 3.

So, the two original expressions are equal only at x = 3,  but they are not equal identically as functions.

Answer:

\(\huge\boxed{y=2x-2}\)

Step-by-step explanation:

The slope-intercept form of an equation of a line:

\(y=mx+b\)

m - slope

b - y-intercept → (0, b)

The formula of a slope:

\(m=\dfrac{y_2-y_1}{x_2-x_1}\)

(x₁; y₁); (x₂; y₂) - points on a line

From the table we have

\((1,\ 0)\to x_1=1;\ y_1=0\\\\(2,\ 2)\to\ x_2=2;\ y_2=2\)

Substitute:

\(m=\dfrac{2-0}{2-1}=\dfrac{2}{1}=2\)

Put the value of a slope and coordinates of the point (1, 0) to the equation of a line:

\(0=2(1)+b\)

\(0=2+b\)          subtract 2 from both sides

\(-2=b\to b=-2\)
