Answer:

24.59 m/s

Step-by-step explanation:

Average speed(m/s) = distance travelled(m) / time taken(s)

Distance = 220 miles

220 miles = 354,056 meters

Time taken = 4 hours

4 hours = 14,400 seconds

Average speed = distance travelled / time taken

= 354,056 / 14,400

= 24.59 meter/seconds

= 24.59 m/s

Answer:

I)

\(2a + 2b = -10\text{ or } 2a + 2b = 10\)

II)

\(2a - 2b = -2 \text{ or } 2a-2b= 2\)

Step-by-step explanation:

We are given that:

\(\displaytstyle a^2 + b^2 = 13 \text{ and } ab= 6\)

I)

Recall the perfect square trinomial pattern:

\(\displaystyle (a+b)^2 = a^2 + 2ab + b^2\)

Rewrite:

\(\displaystyle (a+b)^2 = (a^2 + b^2) + (2ab)\)

Substitute:

\(\displaystyle (a+b)^2 = (13) + (12)\)

Evaluate:

\(\displaystyle (a + b)^2 = 25\)

Take the square root of both sides:

\(\displaystyle a + b = \pm\sqrt{25} = \pm5\)

Hence:

\(\displaystyle 2a + 2b = \pm 10\)

Therefore:

\(\displaystyle 2a + 2b = -10 \text{ or } 2a + 2b = 10\)

II)

Likewise:

\(\displaystyle (a-b)^2 = a^2 - 2ab + b^2\)

Substitute:

\(\displaystyle (a-b)^2 = (13) -(12)\)

Solve:

\(\displaystyle \begin{aligned} (a-b)^2 &= 1 \\ a-b &= \pm \sqrt{1} \\ a-b &= \pm 1\\ 2a - 2b &= \pm 2\end{aligned}\)

In conclusion:

\(2a - 2b = -2 \text{ or } 2a-2b= 2\)

Answer:

Sometimes true.

Step-by-step explanation:

Let's grab the easiest cubic \(y=x^3\)

It is easy to spot that it's always growing over its domain.

For the statement to be true the cubic need to be in the form

\(y= \frac 13 ax^3 +\frac12bx^2+cx + d\) and \(a>0\) and \(b^2-4ac >0\)

Proof is trivial and it's left as an exercise to the reader. No, I'm joking. A cubic function has a quadratic derivative. You know that the sign of the first derivative determine the increase/decrease of the function, depending on sign. In order to be split the way you want it has to have two separate root and a positive leading coefficient.

Step-by-step explanation:

There are two cubes, one with 14 cm and one with 2 cm. 14:2 is equal to 7:1.

\(\sf\longmapsto y=-3x\)

Compare to slope intercept form

\(\sf\longmapsto y=mx+b\)

Initial value

\(\sf\longmapsto y=-3x+0\)

The initial value of the equation is y = -3x + 0.

An equation of the line is defined as a linear equation having a degree of one. The equation of the line contains two variables x and y. And the third parameter is the slope of the line which represents the elevation of the line.

The general form of the equation of the line:-

y = mx + c

m = slope

c = y-intercept

Slope = ( y₂ - y₁ ) / ( x₂ - x₁ )

Given equation is y = -3x

Compare the two equations and get the value of the initial equation.

y = mx + c

y = -3x

Here the value of c is 0.

This measure of central tendency can be considered the most precise in option c. mean

The mean is a measure of central tendency that calculates the average of a set of values. It is often considered the most precise measure because it takes into account all the values in the dataset and provides a balanced representation.

The mean is calculated by summing all the values and dividing by the total number of values. Unlike the mode, which only identifies the most frequently occurring value, and the median, which represents the middle value, the mean incorporates all the values and provides a comprehensive summary of the dataset.

However, it is important to note that the mean can be sensitive to extreme values or outliers in the data.

Step-by-step explanation:

A unit circle is a circle on the coordinate plane with a radius of 1 unit. The unit circle center usually lies on the origin.

The equation of a circle is given as:

(x - h)² + (y - k)² = r²

Where (h, k) is the center of the circle and r is the radius of the circle.

As seen in the diagram attached, the center of the circle is at the origin (0, 0) and the circle is a unit circle with a radius of 1. Hence:

(x - h)² + (y - k)² = r²

(x - 0)² + (y - 0)² = 1²

x² + y² = 1

Given the point P(x, 1/2) lies on the circle. To find x, substitute y = 1/2:

x² + (1/2)² = 1

x² + 1/4 = 1

x² = 1 - 1/4 = 3/4

x² = 3/4

x = √(3/4)

\(x=\pm\frac{\sqrt{3} }{2} \\\\Hence\ P=(\frac{\sqrt{3} }{2},\frac{1}{2} )\ or\ P=(-\frac{\sqrt{3} }{2},\frac{1}{2} )\)

Given that if = 63, 11-47, and the angle between and is 180°, we need to find [proj.

The dot product of two vectors a and b is given as:

`a.b = |a||b| cos(θ)`

where θ is the angle between the vectors.

Let's calculate the dot product of the given vectors.

a = 63 and b = 11-47,

`a.b = (63) (11)+(-47)

= 656

`Now we can use the formula for the projection of a vector onto another vector:

`proj_b a = (a.b/|b|²) b`

The magnitude of b is `|b| = √(11²+(-47)²)

= √2210`

Therefore, `proj_b a = (a.b/|b|²) b`

= `(656/2210) (11-47)`

= `(-2961/221)`

Thus, the answer is option b. 2961.

Step-by-step explanation:

The second Taylor polynomial of a function is a polynomial approximation to that function which is accurate near a particular point x0.

Construct the second Taylor's polynomial P2(x) for f(x)= sin(2x) about x0 = 0

We are to find the second Taylor polynomial for the function f(x) = sin (2x) about the point x0 = 0.

The second derivative of sin(2x) is -4 sin(2x),

so the second Taylor polynomial is given by:

P2(x) = f(x0) + f '(x0)(x - x0) + (1/2!)f ''(x0)(x - x0)²

P2(x) = sin(0) + cos(0)(x - 0) - 2sin(0)(x - 0)²

P2(x) = x - 2x²

Use P2(π/3) to approximate f(π/6)

We haveP2(x) = x - 2x²

Putting x = π/3, we get

P2(π/3) = (π/3) - 2(π/3)²

P2(π/3) = (π/3) - 2(π²/9)

P2(π/3) = (π/3) - (2π²/9)

To approximate f(π/6), we substitute π/6 for x in the original function. We get:

f(π/6) = sin(2(π/6))

= sin(π/3)

Now we use P2(π/3) to approximate sin(π/3):

sin(π/3) ≈ P2(π/3)

= (π/3) - (2π²/9)

≈ (1.05) - (2/3)(3.14)²

≈ 0.6724

We found that the second Taylor polynomial for the function f(x) = sin (2x) about the point x0 = 0 is:

P2(x) = f(x0) + f '(x0)(x - x0) + (1/2!)f ''(x0)(x - x0)²

P2(x) = sin(0) + cos(0)(x - 0) - 2sin(0)(x - 0)²

P2(x) = x - 2x²

We used P2(π/3) to approximate f(π/6) and found that sin(π/3) ≈ P2(π/3) = (π/3) - (2π²/9) ≈ 0.6724

The second Taylor polynomial of a function is a polynomial approximation to that function which is accurate near a particular point x0. The Taylor polynomial can be used to approximate function values near x0.

The equation that could represent each of the graphed polynomial function include the following:

First graph: y = x(x + 2)(x - 3)

Second graph: y = x⁴ - 5x² + 4

In Mathematics and Geometry, a polynomial graph simply refers to a type of graph that touches the x-axis at zeros, roots, solutions, x-intercepts, and factors with even multiplicities.

Generally speaking, the zero of a polynomial function simply refers to a point where it crosses or cuts the x-axis of a graph.

By critically observing the graph of the polynomial function shown in the image attached above, we can logically deduce that the first graph has a zero of multiplicity 1 at x = 2 and zero of multiplicity 1 at x = -3.

Similarly, we can logically deduce that the second graph has a zero of multiplicity 2 at x = 2 and zero of multiplicity 2 at x = -2.

To create a system of constraints that defines a parallelogram, we need to establish conditions that satisfy the properties of a parallelogram: opposite sides are parallel and equal in length, and opposite angles are congruent.

Here's an example of a system of constraints that represents a parallelogram:

Let's consider a parallelogram with vertices (x, y):

1. Constraint 1: Opposite sides are parallel.

  This can be represented by the equation: y = ax + b, where a is the slope and b is the y-intercept.

2. Constraint 2: Opposite sides are equal in length.

  This can be represented by the equation: \((x - x_1)^2 + (y - y_1)^2 = (x - x_2)^2 + (y - y_2)^2\) are the coordinates of two opposite vertices.

3. Constraint 3: Opposite angles are congruent.

  This can be represented by the equation: \(m_1 = m_2\), where \(m_1\) and \(m_2\) are the slopes of two adjacent sides.

By combining these three constraints, we can define a system of equations that represents a parallelogram. The specific values of a, b, (\(x_1, y_1\)), and (\(x_2, y_2\)) will determine the properties and shape of the parallelogram.

The length of the longest possible ladder that can negotiate the turn in the hallway is approximately 16.86 feet.

To find the length of the longest ladder, we can use the Pythagorean theorem, which states that in a right-angled triangle, the square of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the other two sides. In this case, the hallway forms a right-angled triangle, with one side measuring 14 feet and the other side measuring 8 feet.

Using the Pythagorean theorem, we can calculate the length of the hypotenuse (the ladder) as follows:

\(c^2 = a^2 + b^2\)

where c is the hypotenuse (length of the ladder), and a and b are the lengths of the other two sides.

Plugging in the values:

\(c^2 = 14^2 + 8^2\)

\(c^2 = 196 + 64\)

\(c^2 = 260\)

c ≈ √260

c ≈ 16.86 feet

Therefore, the length of the longest possible ladder that can negotiate the turn in the hallway is approximately 16.86 feet.
