Answer:

315 yd

Step-by-step explanation:

CYLINDER VOLUME: A (area) = π x r (radius) ^2

A = π (5)^2

A= 25 π

THEN

You need 5 (the radius) twice so 5^2 which equals 25

2 x π x r^2 (BUT WITH 25) → 2 x 25 π ^2

2 x π x r^2 (BUT WITH ORIGINAL RADIUS 5) → 2 x π(5)

Now multiply 25 x height →25 x 10.6 = 265

2 x 25 π ^2 + 265

2 x 25 = 50 + 265 = 315 π ^2

Answer:

Step-by-step explanation:

The set up given will form a right angled triangle with the length of the ladder as the hypotenuse and distance between the the floor and the top of the ladder as the adjacent side to one of the acute angle 45 degrees.

Using one of the trigonometry identity to calculate How high off the ground  the top of the ladder. According CAH;

cos 45° = Adjacent/Hypotenuse

cos45° = y/13

y = 13cos45°

y = 9.19ft

The ladder is 9.19ft off the ground

Answer:

Out of your 4 options, it's -4.6

Step-by-step explanation:

 The value of [-4.6] is -4. so option D is correct.

We need to find the value of the ceiling function: [-4.6]

As we already know that the ceiling function always occupy the higher value in integers.

i.e. the ceiling function act as follows:

it takes value 0 when   -1< x≤0

1 when  0 < x ≤ 1

2 when  1 < x ≤2.....and so on.

As we know that:

-4.6 lie between -5 and -4.

Hence, we get the value of [-4.6] is -4. so option D is correct.

Answer:

The dimensions of the two different rectangular regions are;

1st Arrangement:

W = 4 yards and L = 5 yards or W = 5 yards and L = 4 yards

2nd Arrangement:

W = 2 yards and L = 10 yards or W = 10 yards and L = 2 yards

The perimeter of the two different rectangular regions are;

1st Arrangement:

P₁ = 18 yards

2nd Arrangement:

P₂ = 24 yards

Step-by-step explanation:

Bella is putting down patches of sod to start a new lawn.

She has 20 square yards of sod.

We are asked to provide the dimensions of two different rectangular regions that she can cover with the sod.

Recall that a rectangle has an area given by

Area = W*L

Where W is the width of the rectangle and and L is the length of the rectangle.

Since Bella has 20 square yards of sod,

20 = W*L

There are more than two such possible rectangular arrangements.

Out of them, two different possible arrangements are;

1st Arrangement:

20 = (4)*(5) = (5)*(4)

Width is 4 yards and length is 5 yards or width is 5 yards and length is 4 yards

2nd Arrangement:

20 = (2)*(10) = (10)*(2)

Width is 2 yards and length is 10 yards or width is 10 yards and length is 2 yards

Therefore, the dimensions of two  different rectangular regions are;

1st Arrangement:

W = 4 yards and L = 5 yards or W = 5 yards and L = 4 yards

2nd Arrangement:

W = 2 yards and L = 10 yards or W = 10 yards and L = 2 yards

What is the perimeter of each region?

The perimeter of a rectangular shape is given by

P = 2(W + L)

Where W is the width of the rectangle and and L is the length of the rectangle.

The perimeter of the 1st arrangement is

P₁ = 2(4 + 5)

P₁ = 2(9)

P₁ = 18 yards

The perimeter of the 2nd arrangement is

P₂ = 2(2 + 10)

P₂ = 2(12)

P₂ = 24 yards

So the perimeter of the 1st arrangement is 18 yards and the perimeter of the 2nd arrangement is 24 yards.

Note:

Another possible arrangement is,

20 = (1)*(20) = (20)*(1)

Width is 1 yard and length is 20 yards or width is 20 yards and length is 1 yard.

Answer:

A = 48 inches ^2

Step-by-step explanation:

The area of a rectangle is found by

A = lw

A = 8* 6

A = 48 inches ^2

We can find the area of the rectangle using the formula below.

Area = length × width

Since the length is 8 inches and the width is 6 inches, we can plug this information into the formula to get (8 in.)(6 in.)

which simplifies to 48 in.².

So the area of the rectangle is 48 in.².

Answer:

f(g(x)) = 2(x^2 + 2x)^2

f(g(x)) = 2x^4 + 8x^3 + 8x^2

Step-by-step explanation:

Given;

f(x) = 2x^2

g(x) = x^2 + 2x

To derive the expression for f(g(x)), we will substitute x in f(x) with g(x).

f(g(x)) = 2(g(x))^2

f(g(x)) = 2(x^2 + 2x)^2

Expanding the equation;

f(g(x)) = 2(x^2 + 2x)(x^2 + 2x)

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

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

f(g(x)) = 2x^4 + 8x^3 + 8x^2
