The diameter of the Earth is 11.3 times less than the diameter of the Jupiter

Fractions are written as a ratio of two integers. Given the following parameters;

Diameter of Jupiter = 1.43•10^5km

Diameter of Earth = 1.27 * 10^4km

Find the ratio

Ratio = Jupiter/Earth

Ratio = 1.43•10^5/1.27*10^4

Ratio = 1.13 * 10^1

Ratio = 11.3

Jupiter = 11.3 of Earth

This shows that the diameter of Jupiter if 11.3 times greater than Earth.

Since the scaling factor of the dilation (0.5) is fewer than 1, it shrinks (make smaller) the triangle around the origin (zero). Intuitively, the dilation is getting the points of the triangle closer to zero (in a way that preserves the shape of the triangle).

Formally, to know the coordinates of a point of the triangle after the dilation, we just need to multiply the original coordinates of the point by the scaling factor (this works for the dilation is around zero).

The original coordinates of D are

Answer:

80,200

Step-by-step explanation:

There is a formula for the sum of a series of numbers from a_1 to a_n.

S = (a_n * a_n+1)/2

This formula means: multiply the last number of the series by what would be the next number, and divide by 2.

The last number you have is 400. The next number would be 401.

Multiply 400 by 401 and divide by 2. That is the sum of the 400 numbers.

S = (401 * 402)/2

S = 160400/2

S = 80200

Answer: The sum is 80,200

Here's a way to understand the formula.

You are adding 400 numbers, from 1 to 400.

Write the first 200 numbers on a line:

1   2   3   4   5   6   7   8   9   10   11   12   13   14   15   ...   198   199   200

Now write the next 200 numbers, from 201 to 400 under these numbers, but start from 400 and go down 1 each number to the right.

You end up with these two lines:

1        2       3        4       5       6        7        8      9        ...     198   199   200

400  399   398   397   396   395   394   393  392    ...    203  202   201

Now add every two numbers in the same column.

1        2       3        4       5       6        7        8      9        ...     198   199   200

400  399   398   397   396   395   394   393  392    ...    203  202   201

------------------------------------------------------------------------------------------------------

401   401   401    401    401    401    401    401   401     ...    401   401   401

Now you have 200 times the number 401.

200 * 401 = 80,200

Answer: 695.30

Step-by-step explanation: We know that 634.8 is what the monthly mortgage is, then we use the value of $726 and divide it by 12 which represents the 12 months in a year. So 726 ÷ 12 = 60.5 therefore monthly he will additionally need to pay that amount. I don't think the annual real estate taxes are going to be used for this problem. So after this, we do the following equation. 634.8 + 60.5 = 695.3. We round this value to the nearest cent and we get 695.30. When the digit to the right is less than 5 we round toward 0... 695.3 was rounded down toward zero to 695.30

The slope is defined as rise/run - in other words, for every step you take horizontally, how many steps you should take vertically to get to a point on the same line.

Answer:

Step-by-step explanation:

Equation of line is given as y = mx + c, where m is the slope and c is the y-intercept.

Since line has slope of 2, equation is y = 2x + c.

Substitute (-8, 1) into the equation to find c

1 = 2(-8) + c

c = 17

Hence, equation of line is y = 2x + 17.

The correct answer is [D]

Hence, the equation of line is y = 2x + 17.

Finding the ratio of "vertical change" to "horizontal change" between any two unique locations on a line yields the slope. Occasionally, the ratio is written as a quotient (also known as a "rise over run"), which produces the same number for every two unique points on the same line. Negative "rise" refers to a diminishing line. The line could be functional, established by a road surveyor, or depicted in a graphic that represents a road or a roof as a description or a design.

The absolute value of the slope is used to determine how steep, incline, or grade a line is. The steeper the line, the larger the absolute magnitude of the slope. A line's direction might be either horizontal, ascending, decreasing, or vertical.

Y = mx + c, where m is the slope and c is the y-intercept, is the equation for a line.

Since the line has slope of 2, equation is y = 2x + c.

Substitute (-8, 1) into equation to find c

1 = 2(-8) + c

c = 17

Hence, the equation of line is y = 2x + 17.

Whereas working with laws of exponents, when splitting the exponential equations with the same base, the exponents ought to be subtracted.

Basically, the Quotient of Powers rules is used to decrease the number of terms when parts like terms with exponents. In order to get the solution, just remove the exponents while dividing the terms with the same base, it is applicable to exponents with the same bases. when powers are multiplied,  for two whole numbers of the same bases the exponents are added, whereas when powers are divided for two whole numbers of the same bases,  exponents are subtracted. The zero exponent rule basically states that when any number is raised to the power of zero it results in 1.

The width of the border will be 8 inches.

In the given question, it is stated that a rectangular board has dimensions of 18*14 around which a person has to put a border of shells. If there are enough shells for the border of an area of 320 square inches, we need to find out the Width of the border.

Firstly, we know the Area of Rectangle is l*b => Length*Breadth

So, now we calculate the area of the board with dimensions l = 18 and b = 14

=> A₁ = l*b

=> A₁ = 18*14

=> A₁ = 252 square inches

We get the Area of the Board as 252 Square inches.

Now, there are shells enough to cover a border area of 320 square inches.

So, the Board and Border area will be A₁ + A, where A₁ and A are the areas of the Board and border respectively.

So, Total Area = 252 + 320

Total = 572 Square inches.

Now, let 'w' be the width of the border. Then the dimensions for the board will be

l = (18 + w)

b = (14 + w)

Using the formula for the Area of the rectangle, we get

=> Total = l * b

=> Total = (18 + w)*(14 + w)

=> 572 = w² + 32m + 252

=> w² + 32m - 320 = 0

=> w² + 40w -8w -320

=> w(w + 40) -8(w + 40)

=> (w+40) (w-8)

We get factors as w = -40 and 8

Since Width can not be negative quantity, width w will be 8 inches.

Hence, the width will be 8 inches for the border.

Writing the given trigonometry expression: cos(2 tan inverse (x)) as algebraic expression gives

Data given in the question are as follows:

cos(2 tan inverse (x))

Using trigonometry (double angle formula)

cos 2x = 1 - 2sin² x

when x = tan inverse (x)

cos(2 tan inverse (x))  = 1 - 2sin² tan inverse (x)        (1)

cos² x + sin² x = 1

cos² x = 1 - sin² x

cos x = √(1 - sin x)

tan x = sin x / cos x

[tex]tan x = \frac{sinx }{\sqrt{1-sin^{2}x } }[/tex]

squaring all parts of the trigonometry expression and clearing the fraction

[tex]tan^{2}x = \frac{sin^{2} x }{1-sin^{2}x }[/tex]

[tex](tan^{2}x) (1-sin^2x) = sin^2x[/tex]

[tex]tan^{2}x-tan^{2}xsin^2x = sin^2x[/tex]

[tex]tan^{2}x = sin^2x+tan^{2}xsin^2x[/tex]

[tex]tan^{2}x = sin^2x(1+tan^{2}x)[/tex]

[tex]sin^2x = \frac{tan^{2}x}{(1+tan^{2}x)}[/tex]

since tan (tan inverse) (x) = x

[tex]1 - 2sin^2 tan^{-1} (x) = 1 - 2x^2 / (1 + x^2)[/tex]

[tex]=\frac{ 1 + x^2 -2x^2}{1+x^2}[/tex]
