Step-by-step explanation:

the angle will always stay the same, it won't change

but if the dialation is 1/2, then that means that the sides will decrease in size compared to the original length,

(just divide by 2) on each side length to get the answer

33.18208

Step-by-step explanation:

This can be solved via Law of Sines, but I´m gonna use sines for the sake of efficiency. :P

So, you have your 3 values and unknown length x.

First set up your proportions: [tex]\frac{sin(65)}{x}=\frac{sin(35)}{21}[/tex]

Cross multiply. [tex]x=\frac{21sin(65)}{sin(35)}[/tex]

Simplify. [tex]x=33.18208[/tex]

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:

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: 90%

Step-by-step explanation:

When 180 is multiplied by 0.90, representing 90%, you get 162 :) So the item was discounted by 10% and is now 90% of it's initial amount

Answer: The original price was discounted by 10%

Step-by-step explanation:

180-162 =  0.1  

1-0.1= 0.9

0.9 * 100= 90%

100% -10%= 90%

90% * 180= 162

5.888x10^12

Step-by-step explanation:

First you got to make the number a decimal, but it can't be above 10 or below 1. So, we end up with 5.888000000000. Then, to get rid of all the zeros, we use the x10^12. The exponent is basically how many times the decimal has to move back to the right to get the original number.

Answer:

Step-by-step explanation:

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:

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

Step-by-step explanation:

A(-1,1), B(-1, -2), C(1, -2)

A geometric figure on a coordinate plane with points. The figure is translated left two units and then reflected over the X axis. The ordered pairs of A, B, C are A (3, 1), B (3,-2), C (1, -2).

"A geometric figure is intuitively defined as a set of points and lines in space."

"The coordinate plane is a two-dimension surface formed by two number lines. One number line is horizontal and is called the x-axis. The other number line is vertical number line and is called the y-axis. The two axes meet at a point called the origin. We can use the coordinate plane to graph points, lines, and more."

We have

A geometric figure on a coordinate plane with points

A = (1, -1)

B = (-1, -2)

C = (1, -2)

The figure is translated left two units and then reflected over the X axis

A drawn figure is attached to the answer

From the figure, we have

Figure is translated left two units

A = (-3 ,1)

B = (-3, -2)

C = (-1, -2)

Then the figure is reflected over x-axis

A = (3, 1)

B = (3,-2)

C = (1, -2)

Hence, The figure is translated left two units and then reflected over the X axis. The ordered pairs of A, B, C are A (3, 1), B (3,-2), C (1, -2).
