Complete the area model representing the polynomial x2 − 11x + 28. What is the factored form of the polynomial? Use the model to
qwelly [4]

Answer:

\boxed{\sf  \ \ \ (x-4)(x-7) \ \ \ }

Step-by-step explanation:

Hello,

from the expression we can say that the sum of the two zeroes is 11 and the product is 28

4 + 7 = 11

4 * 7 = 28

so we can write

x^2-11x+28=(x-4)(x-7)

hope this helps

Alicia records the total number of points scored in two games by 10 players on her basketball team. 28, 13, 4, 8, 15, 10, 22, 7,
madam [21]

Answer:

Choices are missing here.

However, we can find the plot that represents the data.

To draw a scatterplot, we just need to draw points, where the indepedent variable is going to be 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, that is the position of each player.

So, all points we need to draw the plot are:

(1, 28)

(2, 13)

(3, 4)

(4, 8)

(5, 15)

(6, 10)

(7, 22)

(8, 7)

(9, 11)

(10, 15)

The image attached shows the plot that represents this data set.

In the figure, angle ZYX is measured in degrees. The area of the shaded sector can be determined using the formula StartFraction
tensa zangetsu [6.8K]

<u>The given options are:</u>

(A)the central angle measure of the sector divided by the total angle measure of a circle multiplied by the area of the circle will yield the area of the sector.

(B)the central angle measure of the sector divided by the total angle measure of a circle multiplied by the circumference of the circle will yield the area of the sector.

(C)the central angle measure of the sector multiplied by the area of the circle will yield the area of the sector.

(D)the central angle measure of the sector multiplied by the circumference of the circle will yield the area of the sector.

Answer:

(A)the central angle measure of the sector divided by the total angle measure of a circle multiplied by the area of the circle will yield the area of the sector.

Step-by-step explanation:

The area of the shaded sector can be determined using the formula:

\frac{m\angle ZYX}{360^\circ} \cdot \pi r^2

m\angle XYZ=$Central angle of XYZ\\\pi r^2$=Area of a Circle

360^\circ =$Total Angle

Therefore, the formula is:

\dfrac{m\angle ZYX}{360^\circ} \cdot \pi r^2\\\text{Area of XYZ}=\dfrac{\text{Cental Angle of XYZ}}{\text{Total Angle}} X \text{Area of the Circle}

Therefore, the formula is best explained by Option A.
