The physical diameter of the sun will be 1309000km and the percentage of difference between the diameters will be 5.8%.

From the information, the sun has an angular diameter of about 0.5° and an average distance from the Earth of about 150 million km. The angular diameter in radians will be:

= 0.5π / 180

= 0.008727 radians

Distance from the sun = 150 × 10^6

The physical diameter of the sun will be:

= 150 × 10^6 × 0.008727

= 1309000km

The difference between the diameters will be:

= 1390000 - 1309000

= 8.1 × 10^4.

The percentage of difference will be:

= (8.1 * 10^4) / 1390000 × 100

= 5.8%

According to the solving the lengths of right angle triangle using Pythagorean theorem x = 6, y = 3

A fundamental relationship in Euclidean geometry between a right triangle's three sides is known as the Pythagorean theorem or Pythagoras' theorem. According to this rule, the area of the square with the hypotenuse side is equal to the sum of the areas of the squares with the other two sides.

The following is one way to perform the calculation. It may not be the best way.

c = b/cos(α)

= 6

a = √c2 - b2

= √62 - 5.192

= √9.0639

Answer:

Step-by-step explanation:

Answer: 12, 16, 20, and 320.

Step-by-step explanation:

The value of x can be solved as follows, take note of the numbers you will need to drag to complete the equations:

4x + 12x = 320 (segment addition postulate)

16x = 320 (combining like terms)

x = 20 (dividing both sides by 16)

We would end up with the value of x, which equals 20.

Numbers that we end up using are: 12, 16, 20, and 320.

Therefore , the solution of the given problem of surface area comes out to be area of the shaded area equals 50.

The surface area of an object is an estimate of the entire amount of space it takes up. A three-dimensional shape surface area refers to the entire area surrounding it. The overall area of a muti shape is its surface area. The surface area of a cuboid can be calculated by adding the faces of each of its six rectangular sides. The following equation could be used to name the box's dimensions: Surface (SA) equals 2lh, 2lw, and 2hw. The surface area of a three-dimensional shape represents the overall area.

Here,

Square has an area of 100 a 2 = 100 a=10

QC=(1/2) AC=10/2=5,

BR=(1/2), and BD=10/2=5.

what are expressions?

Expressions in math are mathematical statements that have a minimum of two terms containing numbers or variables, or both, nected by an operator in between. The mathematical operators can be of addition, subtraction, multiplication, or division. For example, x + y is an expression, where x and y are terms having an addition operator in between which math, there are two types of expressions, numerical  expressions - that contain only numbers; and algebraic expressions- that contain both numbers and variables.

e.g. A number is 6 more than half the other number, and the other number is x. This statement is written as x/2 + 6 in a mathematical expression. Mathematical expressions are used to solve complicated puzzles.

The correct equation of exponential function is  [tex]f(x) = 6 * (\frac{1}{3} )^x[/tex]

What is an exponential function?

An exponential function is one that has the formula f (x) = [tex]a^{x}[/tex], where x is a variable and a constant that serves as the function's base and must be greater than 0.

Given,

         starting value = 6

          constant ratio = 1/3

The general form of an exponential function

                [tex]f(x) = ab^{x}[/tex]

      where a = starting value i.e when x = 0

                  b = rate of change in exponential equation

  So substituting our given values in the above equation, the exponential function is

           [tex]f(x) = 6 * (\frac{1}{3} )^x[/tex]

Now the value 6 can be divided by 3 only if the value of x = 1

          [tex]f(1) =\frac{6}{3} = 2[/tex]

If x = 5, then equation becomes,

          [tex]f(5) = 6 * (\frac{1}{3} )^5 = \frac{2}{81}[/tex]

So we cannot simply divide 6 by 3 without considering the value of x.

Therefore the correct equation of exponential function is

           [tex]f(x) = 6 * (\frac{1}{3} )^x[/tex]

Answer: The graph that represents a function is the parabola that opens to the left.

This can be determined by the following characteristics of the graph:

It is a parabola because it opens to the left and has a vertex on the y-axis.

It crosses the y-axis at (0, 3) and (0, negative 3), which means that it is symmetric about the y-axis, and also it crosses the x-axis at (9, 0) which means that it is a function.

A circle is not a function because, for any value of x, there are two different values of y that can be plotted on the graph (i.e. the point (5,0) and (-5,0) produce two different y values)

A straight line with a positive slope is not a function because, for any value of x, there is only one value of y that can be plotted on the graph.

So the parabola is the graph that represents a function.

What is an isosceles triangle?

An isosceles triangle in geometry is a triangle with two equal-length sides. It can be stated as having precisely two equal-length sides or at least two equal-length sides, with the latter definition containing the equilateral triangle as an exception.

Here, we have

Given:  An isosceles triangle has congruent sides of 20 cm. The base is 12 cm.

An isosceles triangle has two congruent sides. The height of an isosceles triangle is also the median and the perpendicular bisector of the triangle dividing the base in half and forming two congruent right triangles.

we use the Pythagorean theorem to solve for the triangle's height.

a² + b² = c²

5² + h² = 20²

h² = 400 - 25

h² = 375

h  = 19.36cm

x² - 4x + 4 + y² - 6x + 9 = 16

x² + y² - 4x - 6x + 4 + 9 = 16

x² + y² - 4x - 6x + 13 = 16

Step-by-step explanation:

As you can see in the graph, the distance between tim and jan is creating 2 right triangles

You can solve this using pythagoras theorem,

Triangle (1) :

[tex] x^{2} = {5}^{2} + {12}^{2} \\ {x} = \sqrt{{5}^{2} + {12}^{2} } \\ = \sqrt{169 } \\ = 13[/tex]

X (1) = 13 miles

Triangle (2):

[tex] {x}^{2} = {15}^{2} + {8}^{2} \\ x = \sqrt{ {8}^{2} + {15}^{2} } \\ = \sqrt{289} \\ = 17 [/tex]

X(2) = 17 miles

Now, the distance = x(1) + x(2)

= 13 + 17

=30 miles

Therefore, Tim and Jan are 30 miles apart

The way to determine x, which is the price per pound of the grapes is B. Subtract 5.28 from 7.32 and then divide the difference by 2.4.

To find the price per pound of the grapes, you first needed to find the price of the grapes alone, without the cost of the watermelons.

This price of the grapes can be found by the formula :

= Total cost of fruit - Cost of watermelon

= 7. 32 - 5. 28

= $ 2. 04

Then, you can find the cost of each pound of grapes by the formula :

= Cost of grapes / Pounds of grapes purchased

= 2. 04 / 2 . 40

= $ 0. 85
