Mathematics

Answer:

The answer is 0

Step-by-step explanation:

Let's break this down. . .

x-intercepts are x-intercepts that have 0 as their y.

For example: (9,0) , (5,0),  (3,0) are x-intercept, while (0,9), (0,5), (0,3) are not  x-intercepts.

Graph f(x) = 3x^2 + 4x + 4

There is no x-intercept.

Answer:

They are none x- intercepts on the parabola. To find the x-intercept, substitute in 0 for y and solve for x.

Samuel, Martín y Santiago salen a montar bicicleta de Cali hacia Palmira. La distancia entre Cali y Palmira es de 29.3 KM. En la
myrzilka [38]

Answer:

a) Martín recorrió más distancia, b) A Samuel, Martín y Santiago les falta 7.05, 7.55 y 7.883 kilómetros, respectivamente, c) La distancia recorrida promedio es 21.889 kilómetros, d) Martín recorrió 0.333 kilómetros más que Santiago.

Step-by-step explanation:

a) En primer lugar, convertimos la distancia recorrida por cada persona a su forma decimal:

Samuel

\frac{178}{8}\,km = 22.25\,km

Martin

21\,km + \frac{3}{4}\,km = 21.75\,km

Santiago

21\,km + \frac{5}{12}\,km = 21.417\,km

Como puede apreciarse, Martín recorrió más distancia.

b) La distancia faltante es igual a la sustracción de la distancia recorrida por la persona a la distancia total:

Samuel

x = 29.3\,km -22.25\,km

x = 7.05\,km

Martin

x = 29.3\,km - 21.75\,km

x = 7.55\,cm

Santiago

x = 29.3\,km - 21.417\,km

x = 7.883\,km

A Samuel, Martín y Santiago les falta 7.05, 7.55 y 7.883 kilómetros, respectivamente.

c) La distancia recorrida promedio se obtiene sumando las distancias recorridas de las tres personas y dividiendo el resultado por la cantidad de personas:

\bar{x} = \frac{22.5\,km + 21.75\,km + 21.417\,km}{3}

\bar x = 21.889\,km

La distancia recorrida promedio es 21.889 kilómetros.

d) Esta diferencia se encuentra a restar la distancia recorrida por Santiago a la distancia recorrida por Martín:

x = 21.75\,km - 21.417\,km

x = 0.333\,km

Martín recorrió 0.333 kilómetros más que Santiago.

Emily, Frances, and Bill each carried a 10-pound bag of soil into the backyard. After putting the soil in the first flower bed,
Art [367]

Step-by-step explanation:

emily: 10(5/8) = 6 1/4 or 6.25 pounds left

10- 6.25 = 3.75 used

Frances : 10(2/5) = 4 pounds left

10-4 = 6 pounds used

Bills : 10(2/5) = 4 pounds left

10-4 = 6 pounds used

add them together

15.75 or 15 3/4 pounds of soil in the first flower bed

sergeinik [125]

3.2

Step-by-step explanation:

The Image attached below.

The given fraction is \frac{16}{5}\.

Step 1: Write the numerator inside.and denominator outside.

Step 2: If we multiply a number 5 by 3 we get 15. Write 3 in the quotient place.

Step 3: Now subtract 15 from 16, we get 1

Step 4: Place a decimal point after 3 and give one zero after 1, we get 10.

Step 5: Now multiply 5 by 2, we get 10.

Step 6: Subtract 10 from 10, the remainder is 0.

Step 7: The decimal is 3.2.
