Given that a = 2, b = 3, and c = 4.

To evaluate ab+c, we will plug given values as shown below

ab+c

=2*3+4

=6+4

=10

Hence final answer is 10.

Sara has a stack of 8 plates, each plate is 0.5 inches tall and she is trying to wrap them as a gift.
AlekseyPX

Answer:

The plates will not fit into the box.

Step-by-step explanation:

Each plate is 0.5 inches tall; therefore, the stack of 8 plates will have a height of 0.5in*8 = 4inches.

Also, the diameter of the largest plate is 10 inches or has a radius of 5 inches, which matches the radius of the cylindrical box; therefore, we know that the stack of plates can fit into the base area of the cylindrical box.

What we want to figure out now is the height of the cylindrical box <em>to see if it is greater than or equal to 4 inches</em>—<em>the height of the stack of plates. </em>

The volume of a cylinder is \pi R^2h, and since for our cylindrical box the volume is 150 cubic inches; therefore,

\pi R^2h = 150in^3

putting in R = 5in and solving for height h we get

h = \dfrac{150in^3}{\pi (5)^2}

h = 1.91\: inches,

which is not greater than 4 inches, which means the plates will not fit into the box since the height of the stack is greater than the height of the box.

Ayuda por favor nesecito este ejercicio
Dimas [21]

La función h(x) es uno a uno en su dominio, por lo tanto es invertible. Y la inversa es:

g(x) = [(x + 3)*4 - 5]/(x + 3 - 1)

<h3>¿Es la función h(x) invertible?</h3>

La función esta definida como:

h(x) = -3 + | (5 - x)/(4 - x) |

El dominio es (4, 5] y el rango es [-3, ∞).

Claramente la función es uno a uno en ese intervalo, como podemos ver en el grafico abajo.

Ahora sabemos que la función es invertible en su dominio, entonces debemos encontrar otra funcion g(x) tal que:

h(g(x)) = x

Entonces debemos tener:

-3 + | (5 - g(x))/(4 - g(x)) | = x

| (5 - g(x))/(4 - g(x)) | = x + 3

Podemos remover el valor absoluto:

(5 - g(x))/(4 - g(x)) = x + 3

5 - g(x) = (x + 3)*(4 - g(x))

5 - g(x) + g(x)*(x + 3) = (x + 3)*4

g(x)*(x + 3 - 1) = (x + 3)*4 - 5

g(x) = [(x + 3)*4 - 5]/(x + 3 - 1)

Esa es la función inversa de h(x).
