The equation of the ellipse with a center at (3, 1), a focus at (7, 1), and a vertex at (-2, 1) is given by \(\(\frac{{(x - 3)^2}}{{36}} + \frac{{(y - 1)^2}}{{25}} = 1\).\). In this equation, A = 6, B = 5, C = 3, and D = 1.

To find the equation of the ellipse, we need to determine the values of A, B, C, and D in the general form equation \(\[\frac{{(x - C)^2}}{{A^2}} + \frac{{(y - D)^2}}{{B^2}} = 1\]\)for an ellipse. The center of the ellipse is (C, D), so C = 3 and D = 1.

The distance between the center and each focus is given by the value of A, so we can calculate A as the distance between (3, 1) and (7, 1), which is 4. Therefore, A = 4.

The distance between the center and each vertex is given by the value of B, so we can calculate B as the distance between (3, 1) and (-2, 1), which is 5. Hence, B = 5. Plugging these values into the general form equation, we get \(\(\frac{{(x - 3)^2}}{{36}} + \frac{{(y - 1)^2}}{{25}} = 1\)\) as the equation of the ellipse.

Is this selection (A) the best one? a high positive number. The result of multiplying a negative number by a positive number is always negative.

The result of multiplying two numbers, whether they are positive or negative, is always positive. 3 plus 4 equals 12. The result is minus 12 since there is only one optimistic and one negative number.

Why does adding two negative numbers together results in a positive number?

Repeated subtraction equals multiplication by a negative. Negative numbers were reduced in negative value after they have been multiplied together. Students may easily relate both ideas thanks towards this comparison among both multiplication and addition.

The minimum of y = f(x) occurs at (x,y) = (3,1). Hence y= f(x) >=1 for all other x in its domain of definition.

What is Quadratic equation ?

Quadratic equation can be defined as equation in which it is in the form of ax^2 + bx + c = 0

where c is a constant.

y = f(x) + 3 merely increases the value y by 3 for any x, or just raises its graph up 3. The x-value for its minimum remains at x=3 and y = f(3) + 3 = 1 + 3 = 4.  Hence, new minimum = (3,4)

y = f(x-2) just shifts or translates the graph of f to the right by 2.  So what occurred at x=3 (the minimum y) now occurs at x=5  without changing y = 1.  Hence, new minimum = (5,1).

y = f(1.5x) compresses the x-scale without changing y.  So what happened at x=3 before now happens at x'=2 on the new scale.

Therefore, the minimum point now becomes  (2,1).

In this case we must apply the properties of supplementary angles and opposite angles.

1 .

opposite angles

∠ 1 = 120 °

supplementary angles

∠ 1 + ∠ 2 = 180

The distance between the two towns is 165 kilometers

The initial speed = 100 kilometer per hour

Time taken = t hours

We know,

Speed = Distance / Time

Distance = Speed × t

Distance = 100 × t

New speed = 110 kilometer per hours

He saves 9 minutes

9 minutes = 9/60 hours

The time taken = t - 9/60

The distance = 110 × (t - 9/60)

= 110t - 33/2

Then the equation will be

100t = 110t - 33/2

110t - 100t = 33/2

10t = 33/2

t = 33/2 ÷ 10

t = 33/2 × 1/10

t = 1.65 hours

Then the distance = 100 × t

= 100 × 1.65

= 165 kilometers

Hence, the distance between the two towns is 165 kilometers

The Cartesian equation of the line that contains the points A and B, where A is the intersection point of the given plane with the x-axis and B is the intersection point with the z-axis, is x = 1 and z = 3.

To find the Cartesian equation of the line, we need to determine the values of x and z while allowing y to vary freely. Since point A lies on the x-axis, its y-coordinate is 0, so we have x = 1 and y = 0 for point A. Similarly, since point B lies on the z-axis, its y-coordinate is also 0, so we have z = 3 and y = 0 for point B.

Thus, the equation x = 1 represents the line that contains point A, and the equation z = 3 represents the line that contains point B. Since y can vary freely, we do not include it in the equations. Therefore, the Cartesian equation of the line that contains points A and B is x = 1 and z = 3.

In the conjugate gradient method, if v(k) = 0 for some iteration k, then it can be concluded that Ax(k) = b.

The conjugate gradient method is an iterative algorithm used to solve systems of linear equations. At each iteration, it generates a sequence of approximations x(k) that converges to the true solution x*. The algorithm relies on the concept of conjugate directions and minimizes the residual vector v(k) = b - Ax(k), where A is the coefficient matrix and b is the right-hand side vector.

If v(k) = 0, it means that the current approximation x(k) satisfies the equation b - Ax(k) = 0, which implies Ax(k) = b. This proves that x(k) is indeed a solution to the linear system.

The conjugate gradient method aims to find the solution x* in a finite number of iterations. If v(k) becomes zero at some iteration, it indicates that the current approximation has reached the solution. However, it's important to note that in practice, due to numerical errors, v(k) may not be exactly zero, but a very small value close to zero is typically considered as convergence criteria.

Great! So let’s solve for Joe’s Plumbing charges first. To find his price for 3 hours, solve J(3)=45(3)=$135.

Now let’s find Mark’s Plumbing charges. To find his price for 3 hours, plug 3 into M(t)=40t+25. So, M(3)=40(3)+25=$145.

Therefore, Joe’s Plumbing is cheaper than Matt’s plumbing by 10 dollars for a 3 hour job.

Since minutes are 1/60 of a degree, we can simplify this to cos (79 + 15/60) = cos (78.25). We can use a calculator to find the exact value, which is 0.268954236.

cos 79 15' = cos (79 + 15/60)

= cos (78 + 45/60)

= cos (78 + 0.75)

= cos (78.75)

= cos (78 + 45/60 + 0.25)

= cos (78.25)

= 0.268954236

The cosine of 79 degrees and 15 minutes is 0.268954236. To calculate this, we convert the minutes to 1/60 of a degree and add it to the angle of 79 degrees. Then, we plug 78.25 into the cosine equation and get the result.

To find the base of the parallelogram-shaped patio, we need to use the formula for the area of a parallelogram: A = bh, where A is the area, b is the base, and h is the height. We know that the area of the patio is 580 ft2, so we can set up the equation:

580 = b * h

However, we don't know the height of the parallelogram, so we need to find it first. We can use the formula for the area of a trapezoid (which is a type of parallelogram) to find the height:

A = (b1 + b2) * h / 2

Since we know that the patio is in the shape of a parallelogram, we know that the opposite sides are parallel and equal in length, so we can divide the patio into two triangles and use the Pythagorean theorem to find the height:

h = sqrt(16^2 - (b/2)^2)

where b is the base of the parallelogram (which we're trying to find). Plugging this into the equation for the area of a trapezoid, we get:

580 = (b + b) * sqrt(16^2 - (b/2)^2) / 2

Simplifying this equation (by squaring both sides and rearranging), we get a quartic equation:

16b^4 - 580b^2 + 2304 = 0

This can be factored as:

(b - 24)(b + 24)(b - sqrt(165) / 2)(b + sqrt(165) / 2) = 0

The only positive solution (since the base of the patio can't be negative) is:

b ≈ 24.023

Rounding this to the nearest foot, we get:

b ≈ 24 ft

Therefore, the base of the parallelogram-shaped patio is approximately 24 feet.
