Answer:

Parallel lines ALWAYS have the same slope

Step-by-step explanation:

The equations have unequal slopes, meaning they aren't parallel.

In mathematics, a sequence is an ordered list of elements, often denoted by brackets or parentheses.

The term "a sequence of length n" refers to a sequence that contains a specific number of elements, where the number of elements is denoted by "n."

When the domain of a function is the set of natural numbers (N), it is called an infinite sequence. An infinite sequence can be thought of as an ordered list that continues indefinitely.

I don't have access to the graphs or visual content. However, I can provide you with some general information about the Gateway Arch and help you with some of the questions.

The Gateway Arch is a 630-foot (192 m) monument in St. Louis, Missouri. It is the tallest arch in the world and the tallest man-made monument in the Western Hemisphere. Here are the answers to your questions:

1. The vertex is the highest point on the arch, which is the center or peak of the arch. In the context of the problem, the vertex represents the maximum height or elevation of the arch, which is at the center point.

2. Without knowing the specific question related to "solutions," I cannot answer this question. Please provide more information.

3. To find the quadratic equation in vertex form, we need to use the vertex and another point on the arch. Let's say the vertex is at (0, 630) and another point on the arch is (315, 315). Then we can use the vertex form of the quadratic equation, which is:

y = a(x - h)^2 + k

where (h, k) is the vertex. Plugging in the values, we get:

630 = a(0 - 0)^2 + 630

315 = a(315 - 0)^2 + 630

Solving these two equations simultaneously, we get a = -0.001 and the equation in vertex form is:

y = -0.001x^2 + 630

4. To find the quadratic equation in factored form, we need to use the vertex and another point on the arch. Using the same points as before, we can find the equation in factored form as:

y = a(x - h)(x - p) + k

where (h, k) is the vertex and p is the x-coordinate of the other point. Plugging in the values, we get:

y = a(x - 0)(x - 630) + 630

y = a(x - 315)^2 + 315

Solving these two equations simultaneously, we get a = -0.001 and the equation in factored form is:

y = -0.001(x - 315)^2 + 315

5. Both equations have the same vertex and the same value of a, which means they have the same shape and open downwards. The difference is in the form of the equation, where one is in vertex form and the other is in factored form.

6. The domain of the quadratic equation is all real numbers, as the arch can be any height from 0 to 630 feet.

7. Without knowing the specific location and angle from which the arch is being viewed, I cannot answer this question. Please provide more information.

Step-by-step explanation:

Given parameters:

  Cost of attending the 2-year technical college = $3200;

 His parents intend to give him half the cost;

      Half the cost  = \(\frac{1}{2}\) x $3200 = $1600

The remaining cost  = $3200 - $1600 = $1600

The volume of the figure, by splitting it into two cuboids comes to be 3300 ft³.

The volume of a cuboid is the product of its three dimensions i.e. length, breadth, and height.

Let us split the given figure into two cuboids

So, the volume of the figure will be the sum of the volume of both the cuboids.

So, the volume of the cuboid with dimensions 20 ft x 25 ft x 5ft

= 20 x 25 x 5

=2500 ft³.

The volume of the cuboid with dimensions  4 ft x 25ft x 8ft

=4 x 25x 8

=800 ft³.

So, the volume of the figure = 2500 + 800 =3300 ft³.

Answer:

Step-by-step explanation:For what values of does the equation (2 + 1) have two 2

+ 2 = 10 − 6

real and equal roots?

A quadratic equation that has 2 roots that are equal means that the discriminant  of the equation is 0. The value of k that makes the equation have 2 real and equal roots is \(k = \frac{5}{6}\)

Given that:

\((2k + 1)x^2 + 2x = 10x - 6\)

Rewrite as:

\((2k + 1)x^2 + 2x - 10x + 6 = 0\)

\((2k + 1)x^2 - 8x + 6 = 0\)

A quadratic equation is represented as:

\(ax^2 + bx + c = 0\)

By comparison:

\(a=2k+1\\ b =-8\\\ c =6\)

If an equation has 2 real and equal roots, then:

\(b^2 = 4ac\)

So, we have:

\((-8)^2 = 4 \times (2k + 1) \times 6\)

\(64 = 4 \times (2k + 1) \times 6\)

Divide by 4

\(16 = (2k + 1) \times 6\)

Divide by 6

\(\frac{16}{6} = (2k + 1)\)

\(\frac{8}{3} = 2k + 1\)

Subtract 2 from both sides

\(2k = \frac{8}{3} -1\)

Take LCM

\(2k = \frac{8-3}{3}\)

\(2k = \frac{5}{3}\)

Divide by 2

\(k = \frac{5}{6}\)

Hence, the value of k that makes the equation have 2 real and equal roots is \(k = \frac{5}{6}\)

La edad actual de José es de 30 años.

Para resolver este problema, primero debemos establecer ecuaciones basadas en la información proporcionada. Llamemos "x" a la edad actual de José y "y" a la edad actual de Ana. Según la primera condición, la edad de Ana es la mitad de la edad de José, por lo que podemos escribir la ecuación: y = (1/2)x.

La segunda condición nos dice que dentro de 10 años, sus edades serán dos tercios de sus edades actuales. Esto se puede expresar como: (x + 10) * (2/3) = y + 10.

Reemplazando el valor de y en la segunda ecuación con la primera ecuación, obtenemos: (x + 10) * (2/3) = (1/2)x + 10.

Resolviendo esta ecuación, podemos simplificarla y llegar a: 2(x + 10) = 3[(1/2)x + 10].

Al resolver la ecuación resultante, encontramos que x = 30.

Answer:

the 1&2 , and the 2 and 3 numbers have to match

Using the conditions for continuity, we find that the function D.) is continuous.

A function f(x) is said to be continuous at a point x = a, in its domain if the following three conditions are satisfied:

Since for -4 <= x < -2, -2 <= x < 4 and 4 <= x <= 8, the function f(x) is defined by straight lines , the function will be continuous for all x ≠ -2 and 4. Now for x = -2, 4, let us check all the three conditions:

A.

f(-2) = 0.5 * (-2)² = 2

left hand limit = -2 + 6 = 4

right hand limit = 0.5 * (-2)² = 2

Since, left hand limit is not equal to right hand limit, the function is not continuous at x = -2. No need to check further.

B.

f(-2) = 0.5 * (-2)² = 2

left hand limit = -2 -2 = -4

right hand limit = 0.5 * (-2)² = 2

Since, left hand limit is not equal to right hand limit, the function is not continuous at x = -2. No need to check further.

C.

f(-2) = 0.5 * (-2)² = 2

left hand limit = -2 + 4 = 2

right hand limit = 0.5 * (-2)² = 2

Since, left hand limit is not equal to right hand limit is equal to f(-2), the function is continuous at x = -2.

f(4) = 25 - 3*4 = 13

left hand limit = 0.5 * (4)² = 8

right hand limit = 25 - 3*4 = 13

Since, left hand limit is not equal to right hand limit, the function is not continuous at x = 4.

D.

f(-2) = 0.5 * (-2)² = 2

left hand limit = -2 + 4 = 2

right hand limit = 0.5 * (-2)² = 2

Since, left hand limit is not equal to right hand limit is equal to f(-2), the function is continuous at x = -2.

f(4) = 20 - 3*4 = 8

left hand limit = 0.5 * (4)² = 8

right hand limit = 20 - 3*4 = 8

Since, left hand limit is not equal to right hand limit is equal to f(-2), the function is continuous at x = 4.

Thus, the function is continuous.

An inverse function or an anti function is defined as a function, which can reverse into another function.

The graph of a function changes concavity at inflection points (or points of inflection.

The point (0,-3) is lying on the graph y = g(x), now when we have to find a point lying on y = g-1(x) , the coordinates of this point will reverse as it is the point of inflection. So the coordinates of the point lying of y = g-1(x) will be (-3,0).

GH =?

Step-by-Step Explanation -

We can see from the figure

GH = 5x - 10

GI = 3x

Also, we can see from the diagram

GI = GH

So,

3x = 5x - 10

5x - 3x = 10

2x = 10

x = 10/2

x = 5

Now, putting x = 5 in GH

common denominator = 80        

3/80 and 24/30

Step-by-step explanation:

Same thing as last one, you multiply the denominators of each fraction together. 8x10=80 then multiply the fraction with the opposite denominator, 3x10=30 so 3/80 and 3x8=24 so 24/30.

Answer:

common denominator: 40

3/8 = 15/40

3/10 = 12/40

Step-by-step explanation:

8 x 5 = 40 and 10 × 4 = 40. This means 40 is the common denominator.

To get from 8 to 40 you multiply by 5 and so you multiply 3 by 5. This means the numerator is 15.

To get from 10 to 40 you multiply by 4 and so you multiply 3 by 4. This means the numerator is 12.
