Do these pairs of values (x and y) represent two quantities that are
proportional?


A. Yes, because all of the pairs represent the same ratio.

B. No, because none of the pairs is a simplified ratio.

C. No, because each yvalue is less than the corresponding -value.

Trinomio Cuadrado Perfecto

El producto notable llamado cuadrado de un binomio se expresa como:

[tex](a-b)^2=a^2-2ab+b^2[/tex]

Si se tiene un trinomio, es posible convertirlo en un cuadrado perfecto si cumple con las condiciones impuestas en la fórmula:

* El primer término es un cuadrado perfecto

* El último término es un cuadrado perfecto

* El segundo término es el doble del proudcto de los dos términos del binomio.

Tenemos la expresión:

[tex]\displaystyle \frac{100}{81}m^8p^{12}q^{16}z^2-\frac{20}{63}m^5p^7q^8z^5+ \frac{1}{49}m^2p^2z^8[/tex]

Calculamos el valor de a como la raiz cuadrada del primer término del trinomio:

[tex]\displaystyle a=\sqrt{\frac{100}{81}m^8p^{12}q^{16}z^2}[/tex]

[tex]\displaystyle a=\frac{10}{9}m^4p^{6}q^{8}z[/tex]

Calculamos el valor de a como la raiz cuadrada del primer término del trinomio:

[tex]\displaystyle b=\sqrt{\frac{1}{49}m^2p^2z^8[/tex]

[tex]\displaystyle b=\frac{1}{7}mpz^4[/tex]

Nos cercioramos de que el término central es 2ab:

[tex]\displaystyle 2ab=2\frac{10}{9}m^4p^{6}q^{8}z\frac{1}{7}mpz^4[/tex]

Operando:

[tex]\displaystyle 2ab=\frac{20}{63}m^5p^7q^8z^5[/tex]

Una vez verificado, ahora podemos decir que:

[tex]\displaystyle \frac{100}{81}m^8p^{12}q^{16}z^2-\frac{20}{63}m^5p^7q^8z^5+ \frac{1}{49}m^2p^2z^8=\left(\frac{10}{9}m^4p^{6}q^{8}z-\frac{1}{7}mpz^4\right)^2[/tex]

65,000

Step-by-step explanation:

There are 65000 possibilities of 4 character-password

A password is a security code that is used for verifying identities

The password has 4 characters.

The password must begin and end with a letter.

So the selections are:

First = 26

Last = 25

The other selections are:

Second = 10 digits

Third = 10 digits

So, the number of password is:

Password = 26 * 10 * 10 * 25

Evaluate

Password = 65000

Hence, there are 65000 possibilities of 4 character-password

Polygon Exterior Angle Sum Theorem. If a polygon is convex, then the sum of the measures of the exterior angles, one at each vertex, is 360° .

The graph that represents the function is graph (a)

The function is given as:

r(x) = |x -2|-1

The above function is an absolute value function that is shifted to the right by 2 units, and shifted down by 1 units from its parent function f(x) = |x|

Hence, the graph that represents the function is graph (a)

A. Solid

B. Pyramid

c. Prism

Step-by-step explanation:

Hope it helps you in your learning process.

The terms that correctly describe the object are prism, pyramid, and solid.

Options A, B, and C are the correct answer.

A prism is a three-dimensional object.

There are triangular prism and rectangular prism.

We have,

A prism is a solid geometric shape that has two identical parallel bases, which are typically polygons, and the sides of the shape are parallelograms.

A pyramid is a solid geometric shape that has a polygonal base and triangular faces that meet at a common point called the apex.

A solid is a three-dimensional object that occupies space and has a definite shape and volume.

A polyhedron is a three-dimensional solid that has flat faces, straight edges, and vertices (corners) where the edges meet.

A polygon is a two-dimensional shape that has straight sides and angles and is typically closed (meaning that its sides connect to form a closed shape).

A triangle is a three-sided polygon, meaning it has three straight sides and three angles.

Thus,

The terms that correctly describe the object are prism, pyramid, and solid.

Answer:

Step-by-step ex

its 0.2

Answer:

20.62 feet

Step-by-step explanation:

The ladder propped against a building forms a right angle triangle

Height of the ladder (hypotenuse) = 21 feet

Base of the ladder from the building (adjacent) = 4 feet

Height of the building (opposite) = x feet

Hypotenuse ² = opposite ² + adjacent ²

21² = x² + 4²

21² - 4² = x²

441 - 16 = x²

425 = x²

x = √425

= 20.62 feet

Answer:

0.375 seconds

Step-by-step explanation:

In simple terms, to find the time it took to reach the ground, we need to find t from the equation.

If we differentiate h with respect to t we will get the velocity with which the fireworks is moving at.

[tex]h(t) = - 16t^2 + 4t.\\dh/dt =-32t +4[/tex]

We can now equate this to its velocity and solve for t

10 = -32t +4

t = 0.1875 ( time cannot be negative in value, so we ignore the negative sign)

Therefore, the time it took the fireworks to reach the ground is = 2 x 0.1875= 0.375 seconds.

(We need to account for the fact that the fireworks went up and came down)
