A.
882 m

B.
441 m

C.
10.89 m

D.
0.092 m

Answers

Answer 1

Answer: The answer is C (10.89 m)

x * 9 = 98 m²
x = 98 ÷ 9
x = 10.888888 or 10.89 m

more than in mathematics means addition

So if there are 5 doors, and there are two more windows than doors, then there is 5 + 2 = 7 windows.

So, there is a total of 7 windows.

Cot^2x csc^2x + 2 csc^2x –cot^2 = 2

Answers

Answer:

x = π/2 + πk

Step-by-step explanation:

cot² x csc² x + 2 csc² x − cot² x = 2

Multiply both sides by sin² x:

cot² x + 2 − cos² x = 2 sin² x

Add cos² x to both sides:

cot² x + 2 = 2 sin² x + cos² x

Pythagorean identity:

cot² x + 2 = sin² x + 1

Subtract 1 from both sides:

cot² x + 1 = sin² x

Pythagorean identity:

csc² x = sin² x

Multiply both sides by sin² x:

1 = sin⁴ x

Take the fourth root:

sin x = ±1

Solve for x:

x = π/2 + 2πk, 3π/2 + 2πk

Which simplifies to:

x = π/2 + πk

As shown on the diagram, a regular pyramid has a square base whose side measures 6 inches. If the altitude of the pyramid measures 12 inches, it’s volume, in cubic inches is

Answers

The volume of the given pyramid with a squarebase whose side measures 6 inches and the altitude of the pyramid measures 12 inches is 144 cubic inches. The value is obtained by applying the formula for the volume of the pyramid as $(1)/(3) B_(A)h$ .

The volume of the pyramid:

The volume of the pyramid is given by the formula:

$V=(1)/(3) B_(A)h$

Where,

$B_A$ is the area of the base of the pyramid and

h is the height or altitude of the pyramid

Calculating the Volume:

As shown in the diagram,

The pyramid has a squarebase whose side measures 6 inches and the altitude of the pyramid is 12 inches

Thus,

Area of the square base,

$B_A =a^(2)$

⇒ $B_A=6^2$

⇒ $B_A=36$ sq. inches

Height of the pyramid h = 12 inches

On substituting the values in the formula,

$V=(1)/(3)B_Ah$

⇒ $(1)/(3)$ × 36 × 12

⇒ 4 × 36

⇒ 144 cubic inches

Therefore, the volume of the given pyramid is 144 cubic inches.

Answer:

144 in³

Step-by-step explanation:

The volume of a pyramid of base area A and height h is

V = (1/3)(A)(h).

Here,

V = (1/3)(6 in)²(12 in) = 144 in³
