The area, a, of an ellipse can be determined using the formula a = πxy, where x and y are half the lengths of the largest and smallest diameters of the ellipse.

Answers

Answer 1

Answer:

An equivalent equation solved for y is y = a/πx.

What is an equation?

Two algebraic expressions having same value and symbol '=' in between are called as an equation.

Given:

The area, a, of an ellipse can be determined using the formula a = πxy, where x and y are half the lengths of the largest and smallest diameters of the ellipse.

To find an equivalent equation:

Simplifying,

a = πxy

y = a/πx

Therefore, the equation is y = a/πx

The complete question:

The area, a, of an ellipse can be determined using the formula a = πxy, where x and y are half the lengths of the largest and smallest diameters of the ellipse. Which is an equivalent equation solved for y?

Answer 2

Answer:

Answer:

We have the formula for determing the area of an ellipse : a = Pi * x * y, and we have to find the equivalent equation solved for y. In this formula x is half the length of the largest and y is half the length of the smallest diameter of the ellipse. Pi is approx. 3.14. Starting with: a = Pi * x * y ( we will divide both sides of the equation by: Pi * x ) => a /(Pi*x) = y. Answer: y = a / (Pi*x).

to find the volume of this one we need to break it down
now i see half of a cylinder and rectangle:)
but first lets find the volume of the rectangle...
In order to find the Volume of a rectangle we need to use this formula...
Length x width x height
in this case...
length = 10in
width = 6 in
height = 8in
lets solve:)
10 x 6 x 8 = 480
or we write it like this
480in³

now time to find the volume of the half cylinder:)
But first lets remember the volume for a cylinder
Volume = $\pi r^(2) h$
So lets find our measurements
$\pi$ = 3.14
r² = 5² or 25
h = 6
so lets plug in our values just like our formula said:)
3.14 x 25 x 6
now lets easily solve
3.14 x 25 x 6 = 471
now since we found an entire cylinder and we only want half of a cylinder lets divide our answer in half
471 ÷ 2 = 235.5
so we write it like this 235.5units³
But we have to add both of our multiples together so lets do that
Volume of rectangle = 480in³
volume of half sphere = 235.5units³
480 + 235.5 = 715.5
answer = 715.5units³

What is the value of 7x-2x+3,when x=2

Answers

Well if x = 2, then you do 7 times 2, which is 14, then 2 times 2 which is 4, then 14 minus 4 is 10, and 10 plus 3 is 13.

BIDMAS

2x = 4
4 + 3 = 7
7x = 14
14 - 7 = 7

If the public debt of a country in 2009 was $10,432,000,000,000 and thebudget for 2010 was in deficit by $201,645,000,000, what was the public debt

What is arithmetic?

Arithmetic is a branch of mathematics that deals with the study of numbers, their properties, and their operations. It involves the basic operations of addition, subtraction, multiplication, and division, as well as more advanced operations such as exponents, roots, logarithms, and trigonometric functions.

To find the public debt in 2010, we need to add the 2010 budget deficit to the 2009 public debt.

Public debt in 2010 = 2009 public debt + 2010 budget deficit

Public debt in 2010 = $10,432,000,000,000 + $201,645,000,000

Public debt in 2010 = $10,633,645,000,000

Therefore, the public debt in 2010 was $10,633,645,000,000.
