Answer:

The (i,j) cofactor Cij of A is defined to be

Cij=(−1)ijdet(Mij),

where Mij is the (i,j) minor matrix obtained from A removing the i-th row and j-th column.

Then consider the n×n matrix C=(Cij), and define the n×n matrix Adj(A)=CT.

The matrix Adj(A) is called the adjoint matrix of A.

When A is invertible, then its inverse can be obtained by the formula

Find the area of a regular hexagon with the side length of 10 centimeters. Round to the nearest tenth

Romashka [77]

Polygon area = n * side length^2 / 4 * tan(180/n)
where "n" = number of sides
hexagon area = 6 * 10^2 / 4 * tan(180/6)
hexagon area = 600 / 4 * tan(30)
hexagon area = 600 / 4 * 0.57735
hexagon area = 259.8077422707 square centimeters
hexagon area = 259.8 square centimeters

1000.0 cm3 of a metallic cylinder has a mass of 556 gram. Calculate the density of the cylinder.

natima [27]

Answer:

$\text{Density}=\frac{0.556\text{ Grams}}{\text{ cm}^3}$

Step-by-step explanation:

We are asked to find the density of a cylinder whose volume is 1000.0 cubic cm and mass is 556 grams.

$\text{Density}=\frac{\text{Mass}}{\text{Volume}}$

Substitute the given values:

$\text{Density}=\frac{556\text{ Grams}}{1000.0\text{ cm}^3}$

$\text{Density}=\frac{0.556\text{ Grams}}{\text{ cm}^3}$

Therefore, the density of the metallic cylinder is 0.556 grams per cubic centimeter.

Describe two methods that can be used to find the area of the composite figure.

Zepler [3.9K]

Answer: A composite figure is made up of several simple geometric figures such as triangles, rectangles, squares, circles, and semicircles. To find the area of a composite figure, separate the figure into simpler shapes whose area can be found. Then add the areas together.

Write an equivalent expression by distributing the "-−" sign outside the parentheses:

Katena32 [7]

Answer:

8.9r + (5s + 10)

actually the parenthesis aren't necessary...

8.9r + 5s + 10

Step-by-step explanation:

You can change a subtraction to addition if you change the second term to the opposite sign. This problem is like advanced mode of "Add the Opposite"

8.9r - (-5s - 10)

= 8.9r + (+5s + 10)

= 8.9r + (5s + 10)

= 8.9r + 5s + 10
