Answer:

It has a solution.

Step-by-step explanation:

Step 1: Rearrange 1st equation into slope-intercept form

2x + y = 15

y = 15 - 2x

Step 2: Rearrange 2nd equation into slope-intercept form

x = 15 - 2y

2y + x = 15

2y = 15 - x

y = 15/2 - x/2

Step 3: Rewrite systems of equations

y = 15 - 2x

y = 15/2 - x/2

Since the two lines are not parallel, they will have a solution.

Let x= number of watches sold

Ethan= x(14) + (20)(1.50)

Roy = x(13.50) + (20)(1.80)

Since they collected the same amount of money:

14x + (20)(1.50) = 13.50x + (20)(1.80)

Combine like terms:

14x - 13.50x = (20)(1.80) - (20)(1.50)

0.50x = 36 - 30

0.50x = 6

The set of shapes that are a correct decomposition of a regular hexagon are A. Six equilateral triangles

The regular hexagon may be partitioned into a collection of six congruent equilateral triangles through the act of drawing lines that interconnect its vertices with its center.

The rationale behind this phenomenon can be elucidated by the fact that the collective sum of the interior angles of a regular hexagon amounts to 720 degrees. This value is precisely twice the angle measurement of an equilateral triangle. Consequently, it can be deduced that the angle measurement of each of the six equilateral triangles which form the hexagon is 120 degrees.

Step-by-step explanation:

The height CD of the cone is found using the Pythagorean theorem.

  BC² + CD² = BD²

  8² + CD² = 17²

  CD = √(289 -64) = 15

The volume of the cylinder is ...

  V = πr²h

The volume of the cone is ...

  V = 1/3πr²h

So, the portion of the cylinder not occupied by the cone is ...

  V = (πr²h) -(1/3πr²h) = (2/3)πr²h

  V = 2/3(π)(8 m)²(15 m) = 640π m² . . . . . matches choice D

The radius of the semicircle protractor is approximately 4.693 cm.

So, the maximum volume of the cone is approximately 1047.19 cubic inches.

The volume of a cone is given by the formula V = (1/3) * pi * r^2 * h, where r is the radius of the base and h is the height of the cone. In this case, the height of the cone is the radius of the circle, which is 10 inches, and the radius of the base is half the length of the circumference of the sector, which is (theta/360) * 2 * pi * 10 inches.

We want to find the value of theta that maximizes the volume of the cone. We can do this by taking the derivative of the volume formula with respect to theta, setting it equal to 0, and solving for theta.

V = (1/3) * pi * r^2 * h

= (1/3) * pi * ((theta/360) * 2 * pi * 10)^2 * 10

= (1/3) * pi * (theta/36)^2 * 100

dV/dtheta = (2/3) * pi * (theta/36) * (100/36)

= (2/3) * pi * theta/36

Setting dV/dtheta = 0 and solving for theta, we get theta = 0.

Since the magnitude of theta must be positive, the maximum volume occurs when theta = 0, which means that the entire circle is used to form the cone. The maximum volume of the cone is then

V = (1/3) * pi * r^2 * h

= (1/3) * pi * (10)^2 * 10

= (1/3) * pi * 100 * 10

= (1/3) * pi * 1000

= approximately 1047.19 cubic inches

Answer:

sorryyyyyy dont knowwwwwwww

since vectors v1 and v2 are parallel, the system xv1 + yv2 = v3 will have infinitely many solutions regardless of the specific values of v1, v2, and v3.

Geometrically, this is due to the fact that v1 and v2 span the same direction in space, so any combination of x and y will still lie on the same line or in the same direction.

Since vectors v1 and v2 are parallel, they lie on the same line or are scalar multiples of each other. Let's analyze the possible cases geometrically:

1. **Vectors v1 and v2 are collinear (lie on the same line):**

  In this case, any combination of x and y that satisfy the equation \(xv1 + yv2 = v3\) will lie on the same line as v1 and v2. This means there are infinitely many solutions for x and y.

2. **Vectors v1 and v2 are scalar multiples of each other:**

  If v1 and v2 are scalar multiples of each other, then they represent the same direction in space. In this case, any combination of x and y that satisfy the equation will give a vector that lies on this line (spanned by v1 and v2), which is also the direction of v3. Hence, again there are infinitely many solutions.

3. **Vectors v1 and v2 are not collinear but have different directions:**

  This scenario is not possible because you stated that v1 and v2 are parallel. If they have different directions, they would not be parallel.

(a) To compute the experimental probability of rolling a 1 or 6 from Latoya's results, we need to determine the number of times a 1 or 6 was rolled and divide it by the total number of rolls Latoya made.

Let's assume that Latoya rolled the dice 100 times and obtained 20 1's and 10 6's. The total number of successful outcomes (rolling a 1 or 6) is 20 + 10 = 30.

Therefore, the experimental probability of rolling a 1 or 6 is 30/100 = 0.3 or 30%.

(b) Assuming the cube is fair, the theoretical probability of rolling a 1 or 6 can be determined by considering the favorable outcomes (rolling a 1 or 6) divided by the total possible outcomes (rolling any number from 1 to 6).

Since there are two favorable outcomes (1 and 6) out of six possible outcomes (1, 2, 3, 4, 5, 6), the theoretical probability is 2/6 = 1/3 or approximately 0.3333.

(c) The correct statement is B. As the number of rolls increases, we expect the experimental and theoretical probabilities to become closer, though they might not be equal. This is due to the law of large numbers, which states that as more trials are conducted, the experimental probability tends to converge towards the theoretical probability. However, it is not necessary for them to be exactly equal. Random variations can cause some discrepancy, but with a larger number of rolls, the experimental probability should approach the theoretical probability more closely.

What is known as a triangle?

The three vertices of a triangle make it a three-sided polygon. The angles of the triangle are formed by the connection of the three sides end to end at a single point.

                            The triangle's three angles add up to a total of 180 degrees.

  The lengths are given as a = 725 feet, b = 650 feet, and c = 575 feet.

Since, we know the fact that angle opposite to largest side is greatest. Hence, the largest angle would be opposite to side a.

Now, use the law of cosine

          cosA = b² + c² - a²/2bc

On substituting the values, we get

      cosA = (650)² + ( 575 )² - ( 725)²/2*650*575

The graph of f(x) = x(x+5)(x+3) / (x+3)(x+5) bears resemblance to the line y=x since both plots share similar linear characteristics.

Both the numerator and denominator of f(x) = x(x+5)(x+3) / (x+3)(x+5) cancel out the factors (x+3) and (x+5), giving us a simplified expression for the function, f(x) = x.

A line with a slope of 1 passes through the origin in an upward direction. When we examine the graph of y=x, which is a straight line passing through the origin with a slope of 1, it becomes apparent that adding 1 to x also adds 1 to y.

Since the simplified expression is merely f(x) = x, we can deduce that the graph of this function follows a linear path passing through the origin with a slope of 1.

The g graph exhibits a four-fold vertical stretch.

The graph of f (x)=\(x^{2}\) is translated up to two units, then reflected in the X-axis.

The rule for g.

Identify the vertex​

The g graph exhibits a four-fold vertical stretch.

=> g = 4f(x) (x)

an X-axis reflection

=> g = - 4f(x) (x)

(X-axis reflection of (X, Y) is (x , - y)

a conversion two units higher

=> g = -4f(x) + 2

f(x) = x²

=> g = - 4x² + 2

Vertex is at  ( 2, 0)

What is a vertical stretch?

When a base graph is multiplied by a particular factor larger than 1, vertical stretch happens. As a consequence, the graph is stretched outward while keeping the input values (or x). We anticipate that the y values in a function's graph will be further away from the x-axis when it is vertically extended.

How to vertically stretch a function?

When given a function’s graph, we can vertically stretch it by pulling the curve outwards based on the given scale factor. Here are some things to remember when we vertically stretch functions:

Ensure that the values for x remain the same, so the base of the curve will not change.

This means that when applying vertical stretches on a base graph, its x-intercepts will remain the same.
