B. It cant be A because a negative leading coefficient would mean it was turned facing down. It can't be C because the bottom of the loop is a turning point. It cant be C because it doesn't cross the x-axis.

Answer:

B. The function has an even degree.

Step-by-step explanation:

A. The function has a negative leading coefficient.

When a function has negative leading coefficient, then it opens downward.

But in this case the graph is opened upwards.

B. The function has an even degree.

As the graph is symmetric about y axis, so the value of f(x) at both x and -x will be same. (for any x and -x, the value of y is same.)

And in even functions f(x)=f(-x), so this graph has even degree function.

C. The function has zero turning points.

Turning point is where f(x) changes it sign. In this case f(x) changes from -ve to +ve at x=2, so it has one turning point.

D. The function has one x-intercept.

x-intercept is where the graph intersects x-axis. In this case the graph doesn't even touch the x axis, so it doesn't have any x-intercept.

Identify the slope y-intercept of the function y= -2x + 3.

Anna11 [10]

Answer:

First option.

Step-by-step explanation:

Use the formula y = mx + b.

Where m is the slope, and b is the y-intercept.

y = -2x + 3

The slope is -2. The y-intercept is (0, 3).

Determina la masa molar y el volumen que ocupa la siguiente sustancia CO2, si su masa es de 28 gr. *

balandron [24]

Answer:

Para el CO₂ sabemos que:

densidad = 0,001976 g/cm³

Sabemos que:

densidad = masa/volumen

Entonces, si tenemos una masa de 28 g, podemos escribir:

volumen = masa/densidad

volumen = (28g)/(0,001976 g/cm³) = 14,170 cm^3

Para obtener la masa molar (es decir, la masa de un mol de esta sustancia) simplemente sumamos la masa de un mol de cada componente.

Carbono: tiene una masa molar de 12 g/mol

Oxígeno: tiene una masa molar de 16 g/mol (y tenemos dos oxígenos)

entonces la masa molar va a ser:

masa molar = 12g/mol + 2*16g/mol = 44 g/mol

Es decir, un mol de CO₂, pesa 44 gramos.

Which of the following demonstrates how the 20 is calculated using the combination pattern

UNO [17]

The combination expression that demonstrates how the 20 is calculated using the combination pattern is 6C3

<h3>Permutation and Combination</h3>

While combination has to do with selection, permutation has to do with arrangement.

According to the combination rule

nCr = n!/(n-r)!r!

The expression that gives the result of 20 is expressed below;

6C3 = 6!/(6-3)!3!

6C3 = 6!/3!3!

6C3 = 6!/6*6
6C3 = 720/36
6C3 =20

Hence the combination expression that demonstrates how the 20 is calculated using the combination pattern is 6C3
