By using trigonometric relations, we can see that the hypotenuse of the right triangle measures 30.8 units.

Here we will need to use trigonometric relations. We want to find the value of x, which is the hypotenuse of the right triangle.

We know the measure of one angle, and the adjacent cathetus to said angle, the measures are:

angle = 65°

Cathetus = 13 units.

Now we can sue the trigonometric relation:

cos(a) = (adjacent cathetus)/(hypotenuse)

Replacing what we know, we can rewrite that as:

cos(65°) = 13/x

Now we just need to solve the equation for x, we will get:

x = 13/cos(65°) = 30.8 units.

We conclude that the hypotenuse of the right triangle measures 30.8 units.

∠ D2 = 16°

Step-by-step explanation:

complementary angles sum to 90° , then

∠ D1 + ∠ D2 = 90°

74° + ∠ D2 = 90° ( subtract 74° from both sides )

∠ D2 = 16°

If two angles are complementary they add up to a total of 90 degrees.

So we know that

D1+D2=90, because the problem tells us they're complementary

Now, we know as well that D1 = 74, so we can plug it into the little equation and solve in terms of D2.

[tex]D1+D2=90[/tex]

[tex]74+D2=90[/tex]

The solution using indices for the given equation is (x = 5/3).

For the given expression in question;

8 × 8⁴ˣ⁻³ = 512 × 8ˣ

By the property of indices, if the base is equal; then the powers are added with sign.

8⁴ˣ⁻³⁺¹ = 512 × 8ˣ

As, we know that 512 is the cube of 8.

8⁴ˣ⁻² = 8³ × 8ˣ

Apply the power law on right side;

8⁴ˣ⁻² = 8³⁺ˣ

As, the base on both side is equal, then the exponents are also equal.

Thus,

4x - 2 = 3 + x

Bring variables and constants on different sides.

4x - x = 3 + 2

In mathematical expression the given expression is written as;

⇒ S + 12 = x² + 2x + 4

Where, S is area of square with side x.

What is Area of square?

A square is a two dimension figure in which all the sides are equal. Since all the sides are equal, the area would be two times the side of a square.

Let a side of square is x feet.

Then, Area of a square (S) = x²

When, The side of the square is increased by 2 feet. Then area is increase by 12 sq. ft.

Then, Side of a square = (x + 2)

Hence, Area of a square = (x + 2)²

Answer:

The values of x are -6 + √5 and -6 - √5.

Step-by-step explanation:

It is given that we need to find all of the points of the form (x,-1) which are 3 units from the point (-6, 1).

Now, let us suppose that these points are in 2D coordinate system such as;

=> (x1, y1) = (-6, -1)

and let us suppose that the other point is;

=> (x2, y2) = (x, 1)

Further, the distance between both these points them is 3 units and we can write this as;

=> d = √(x1 - x2)² + (y1 - y2)²

=> 3 = √(-6 - x)² + (-1 - 1)²

After squaring both the sides;

=> 9 = 36 + x² + 12x + 4

=> 9 = x² + 12x + 40

On rearranging the equation;

=> x² + 12x + 31 = 0

Now, this is a quadratic equation of the form ax² + bx + c = 0 in which;

=> x = -b ± √(b² - 4ac) / 2a

After putting values in this for obtaining the value of x on comparing we get;

=> x = -12 ± √(12² - 4×31) / 2

=> x = -12 ± √(144 - 124) / 2

=> x = -12 ± √20 / 2

=> x = -12 ± 2√5 / 2

=> x = 2(-6 ± √5) / 2

=> x = -6 ± √5

Therefore, the values of x are -6 + √5 and -6 - √5.

Hence, Option B is the correct answer.

What is translation?

A translation in math moves a shape left or right and/or up or down. The translated shapes look exactly the same size as the original shape, and hence the shapes are congruent to each other.

Given that,

The translation is 1 units left and 5 units up.

The coordinates of the given figure are R(-3, -3), S(-3, -1), T(2, 0) and

U(1, -5).

Now, If the translation is 1 units left and 5 units up, then the coordinates become (x - 1, y + 5).

Hence, Coordinates for the image of the graph are;

R' = (-4 - 1, 2 + 5) = (-5, 7)

S' = (-3 - 1, -1 + 5) = (-4, 4)

T' = (2 - 1, 0 + 5) = (1, 5)

U' = (1 - 1, -5 + 5) = (0, 0)

Hence, The coordinates are R'(-4, 2), S'(-4, 4), T'(1, 5) and U' (0, 0).

Therefore, The figure with the coordinates R'(-4, 2), S'(-4, 4), T'(1, 5) and

Step-by-step explanation:

The  absolute difference is 492 people per square mile and Relative difference: 435.4%.

Thus, option (B) is correct.

To find the absolute difference between the two population densities, subtract the population density of country A from the population density of country B:

Absolute difference = Population density of country B - Population density of country A

                                 = 605 people per square mile - 113 people per square mile

                                 = 492 people per square mile

Now, the relative difference as a percentage, we use the formula:

Relative difference = (|Absolute difference| / Population density of country A) * 100

                                = (|492| / 113) * 100

                               = (492 / 113) * 100

                               = 4.35398230088 * 100

                               = 435.4%
