Answer:

Step-by-step explanation:

The measure of the two greatest angles is 105° and 45°

Let the angles be 2x, 3x and 7x ...... (i)

According to the 'Angle Sum Property' of triangle,

2x + 3x + 7x = 180°

12x = 180°

x = 15°

Now, put value of x in (i)

2x = 2 × 15 = 30°

3x = 3 × 15 = 45°

7x = 7 × 15 = 105°

so, the two greatest angles are 105° and 45°

The transformation given to the parent function f(x)=sin(x) given the graph of the equation g(x)=sin(3x)-4 will be C. The graph is horizontally compressed by a factor of 1/3 and shifts up 4 units.

The parent function f(x) = sin(x) has been transformed by replacing x with 3x in the argument of the sine function.

This results in a horizontal compression of the graph by a factor of 1/3. In addition, the graph of g(x) = sin(3x) is shifted upward 4 units, as indicated by the subtraction of 4 from the value of the sine function.

The correct option is C.

Equations 4 and 5 are not equivalent to any of the other equations.

The definition of an equation in algebra is a mathematical statement that demonstrates the equality of two mathematical expressions. For instance, the equation 3x + 5 = 14 consists of the two equations 3x + 5 and 14, which are separated by the 'equal' sign.

The equations that are equivalent are:

2 + x = 5

Negative 5 + x = negative 2

x + 1 = 4

Subtracting 2 from both sides, we get x = 3. Therefore, the equation is equivalent to x = 3.

Adding 5 to both sides, we get x = 3. Therefore, the equation is equivalent to x = 3.

Subtracting 1 from both sides, we get x = 3. Therefore, the equation is equivalent to x = 3.

Answer: I do not have the capability to create a graph. However, I can tell you how to graph the parabola h(x) = -x^2 + 3.

A parabola is defined by its equation in the form y = ax^2 + bx + c, where a, b, and c are constants. In this case, a = -1, b = 0, and c = 3.

The vertex of the parabola is the highest or lowest point on the graph and is given by the coordinates (-b/2a, c - b^2/4a). For this parabola, the vertex is (0, 3), since b = 0 and a = -1.

To find another point on the parabola, you can plug in any x-value and use the equation of the parabola to find the corresponding y-value. For example, if you plug in x = -2, you get:

h(-2) = -(-2)^2 + 3

h(-2) = 4 + 3

h(-2) = 7

So the point (-2, 7) is also on the parabola.

With the vertex and one other point on the parabola, you can now graph the parabola.

Answer: The momentum of the truck before the collision is given by the formula:

p_i = m_i * v_i, where m_i is the mass of the object and v_i is its velocity.

The momentum of the truck before the collision is:

p_i (truck) = 3000 kg * 10 m/s = 30000 kg m/s

The momentum of the car before the collision is:

p_i (car) = 1000 kg * 0 m/s = 0 kg m/s

The total initial momentum of the system is the sum of the initial momenta of the truck and car:

p_i (total) = p_i (truck) + p_i (car) = 30000 kg m/s + 0 kg m/s = 30000 kg m/s

After the collision, the final momentum of the system is the sum of the final momenta of the truck and car:

p_f (total) = p_f (truck) + p_f (car)

Let's call the velocity of the truck after the collision v_f (truck). The final momentum of the truck is:

p_f (truck) = 3000 kg * v_f (truck)

The final momentum of the car is:

p_f (car) = 1000 kg * 15 m/s = 15000 kg m/s

Using the conservation of momentum, we can write an equation:

p_f (total) = p_i (total)

30000 kg m/s = p_f (truck) + p_f (car)

30000 kg m/s = 3000 kg * v_f (truck) + 15000 kg m/s

30000 kg m/s = 3000 kg * v_f (truck) + 15000 kg m/s

v_f (truck) = (30000 kg m/s - 15000 kg m/s) / 3000 kg = 7.5 m/s

So, the velocity of the truck immediately after the collision is 7.5 m/s.

Step-by-step explanation:

The expression (m + 8) - (5m + 11) simplifies to -4m - 3.

From the question, we have the following parameters that can be used in our computation:

Subtract 5m + 11 and m + 8

To subtract (5m + 11) from (m + 8), we need to distribute the negative sign to each term inside the first set of parentheses:

(m + 8) - (5m + 11)

Open the brackets

= m + 8 - 5m - 11

Evaluate the like terms

= -4m - 3

Hence, (m + 8) - (5m + 11) simplifies to -4m - 3.

The longest border of the Mann's park is 228.6 meter.

The Triangle Inequality It is a basic principle of geometry that the lengths of any two sides of a triangle must add up to more than the length of the third side. In other words, the longest side of any triangle must be shorter than the total length of the other two sides.

In this case, the shortest side of Mann Park measures 5 inches, and the two longer sides measure 7 inches and 9 inches.

So, the sum of the lengths of the two longer sides is:

' 7 inches + 9 inches = 16 inches.

Since 5 inches is less than 16 inches, we know that the 5-inch side is the shortest side, and the 9-inch side is the longest side.

One inch is approximately equal to 0.0254 meters, so we have:

= 9 inches x 0.0254 meters/inch

= 0.2286 meters

Since the shortest side is 1000 meters long, the longest side is:

= 1000 meters x 0.2286 meters/inch

= 228.6 meters long.

Therefore, the longest border of Mann Park is approximately 228.6 meters long.

Answer:

32/13

Step-by-step explanation:

To evaluate the expression Z₂ * Z3 / Z₁, we first need to find the complex numbers Z₂ * Z3 and Z₁.

Z₂ * Z3 = -2 + 3i * 4 + 2i = (-8 + 14i) + (-6 + 6i) = -8 + 8i

Z₁ = 3 - 2i

So, Z₂ * Z3 / Z₁ = (-8 + 8i) / (3 - 2i)

We can simplify this expression by multiplying the numerator and denominator by the complex conjugate of the denominator, which is (3 + 2i).

Z₂ * Z3 / Z₁ = (-8 + 8i) / (3 - 2i) * (3 + 2i) / (3 + 2i) = (-8 + 8i) * (3 + 2i) / (3 - 2i) * (3 + 2i)

Z₂ * Z3 / Z₁ = ((-8 * 3 + 8 * 2i) + (8 * 3 + 8 * 2i)) / (3^2 + (-2i)^2) = (16 + 16i) / 13

Therefore, Z₂ * Z3 / Z₁ = (16 + 16i) / 13.

The average rate of change of the function over the interval (-1, 2) is 3.

Average rate of change of a function is defined as the rate at which the value of the function is changing with respect to the change in the input values.

Difference quotient of a function over an interval is also the same concept as the average rate of change of a function.

Average rate of change of a function f(x) over an interval (a, b) is [tex]\frac{f(b) - f(a)}{b-a}[/tex].

Given interval is (-1, 2).

From the graph, f(-1) = -4 and f(2) = 5

Average rate = [tex]\frac{f(2) - f(-1)}{2--1}[/tex] = (5 - -4) / (3) = 9/3 = 3

Answer: The amount of alcohol the woman consumed can be calculated as follows:

Two glasses of wine * 22 grams of alcohol per glass = 44 grams of alcohol

To convert this amount to milliliters, we need to know the concentration of the alcohol, which is typically around 12% for wine. So, 44 grams of alcohol is equivalent to 44 grams / 0.12 g/mL = 367 mL.

Next, we can calculate the woman's blood alcohol content (BAC) using the following formula:

BAC = (Alcohol consumed in mL) / (Blood volume in mL) * 100%

The blood volume for a 103-pound woman with approximately 6 liters of blood can be estimated as follows:

6 liters * 1000 mL/liter = 6000 mL

So, the BAC can be calculated as follows:

BAC = (367 mL) / (6000 mL) * 100% = 0.0612 * 100% = 6.12%

Therefore, the woman's blood alcohol content would be 6.12% if all the alcohol were immediately absorbed into her bloodstream.

Slope line formula is used for determining the slope of a line. Based on the given points, the slope of line is 2/3.

To find the slope of the line passing through the given points, we can use the slope formula, which states that the slope of a line passing through two points (x1, y1) and (x2, y2) is given by the expression:

slope = (y2 - y1) / (x2 - x1)

Using this formula, we can calculate the slope of the line passing through the three given points as follows:

slope = (2 - (-2)) / (3 - (-3)) = 4/6 = 2/3

Therefore, the slope of the line passing through the given points is 2/3.

Alternatively, we can observe that the three points are collinear and lie on the same straight line. We can use this fact to find the slope of the line by computing the rise over run between any two of the points. For example, using the points (0,0) and (-3,-2), we have a rise of 2 and a run of 3, so the slope is 2/3. This confirms that the slope of the line passing through the given points is 2/3.
