For the given relation, the domain is  [0,70] and the range is   [0,500].

What is meant by relation?

In mathematics, a relation describes the connection between two distinct sets of data. If more than two non-empty sets are taken into consideration, the relationship between them will be determined if there is a connection between their items. The relationship between two or more sets of values is called a relation.

Assume that there are two sets of ordered pairs, x and y. If set x and set y are related, then the values of set x are referred to as the domain while the values of set y are referred to as the range.

W can also determine domain and range from graphs.

Also, note that the given graph is continuous so the domain and range values all all values in an interval.

The domain represents all the input values which are on the x-axis.

From the given graph, we can see that the domain values are in the interval  [0,70].

The range represents all output values which are on the y-axis.

From the graph, the range values are in the interval [0,500].

Therefore for the given relation, the domain is  [0,70] and the range is   [0,500].

Answer:

y=-2/5x

Step-by-step explanation:

The slope-intercept form of a linear function is y = mx +b, where m is the slope and b is the y-intercept.

Currently, 2x + 5y = 0 is in standard form and we can convert it to slope intercept form by simply isolating y (put the equation in terms of y):

[tex](2x+5y=0)-2x\\(5y=-2x)/5\\y=-2/5x[/tex]

The equation of a line perpendicular to line y = 1/5x-2 in slope-intercept form that contains point (-3, 1) is y = -5x - 14.

Mathematically, the point-slope form of a straight line can be calculated by using this mathematical expression:

y - y₁ = m(x - x₁)

Where:

From the information provided, an equation of the first line WX is given by;

y = x/5 - 2

Therefore, slope (m) = 1/5

In Mathematics, a condition that must be met for two lines to be perpendicular is given by:

m₁ × m₂ = -1

1/5 × m₂ = -1

m₂ = -5.

At point (-3, 1), an equation of the line can be calculated by using the point-slope form as follows:

y - y₁ = m(x - x₁)

y - 1 = -5(x - (-3))

y - 1 = -5(x + 3)

y = -5x - 15 + 1

y = -5x - 14

Answer: Let's call the number of pages printed "x". After printing x pages, the total cost for the Hewlett-Packard printer will be:

$200 + $0.03 * x

And the total cost for the Brother printer will be:

$240 + $0.01 * x

We want to find the number of pages "x" such that the cost of the two printers is the same, i.e., when:

$200 + $0.03 * x = $240 + $0.01 * x

We can isolate x by subtracting $240 from both sides and subtracting $0.01 * x from both sides:

$200 - $240 + $0.03 * x - $0.01 * x = 0

$-40 + $0.02 * x = 0

$0.02 * x = 40

x = 2000

So, the number of pages that need to be printed for the cost of the two printers to be the same is 2000 pages.

The height of the right cone will be 9.86 units.

The area a cone takes up in a three-dimensional plane is known as its volume. A cone's base is circular, so it is made of a radius and a diameter.

Given that the volume of the cone is 2325 cubic units and the radius of the cone is 15 units.

The height of the cone will be calculated as:-

Volume = 2325

(1/3)πr²h = 2325

( 1/3 ) x π x 15)² x h = 2325

h = ( 2325 x 3 ) / ( 15 x 15 x π )

h = 9.86 units

Step-by-step explanation:

For me in class there were 6 parts to this problem and this problem is the same in my class so I will add all the answers

So for how many grams of 25% syrup it will be 120-x because the some amount + x = 120 grams of 15% syrup

so 120-x = the some amount of syrup.

This will be the answer for the problem you were asking for

If you have 6 parts keep scrolling since I will supply some more answers

Next part: How much pure sugar is in the 25% syrup?

For the amount of pure sugar there is in the 25% syrup

that will equal 0.25(120-x) = 30-0.25x

Next: How much sugar is in 120 grams of 15% sugar syrup?

10% of 120 is 12

5% = 12/2 = 6

12+6 = 18

Now the earlier stuff from the problem will come in handy

use the previous answers to write an equation

0.25(120-x)+0.10x=18

= 30-0.25x+0.10x=18

30 -0.15x=18

Now the final part to solve the equation and find the 10% solution and the 25% solution

-0.15x=18-30 = -12

-0.15x=-12

x= -12/-0.15

x=80

The balance account is prepared in accordance with the provided statement, and both the liabilities and assets total 2800000.

A balance sheet provides you with a quick overview of ones company's financial standing at any particular moment. A balance sheet, along with a revenue statement as well as a cash-flow statement, can aid business leaders in assessing the financial health of their organisation.

Computation of Current assets and Current Liabilities

Current Ratio  (CR) = Current Assets (CA)/ Current Liabilities (CL)  = 2.5

So, CA= 2.5 CL

Current Assets (C.A) - Current Liabilities (C.L) now equals Rs. 60000 as working capital.

Therefore, CA - CL = 60000 0

     2.5 CL-CL = 600000

     1.5 CL = 600000

        CL = 600000/1.5

     C.L = Rs.40000 0

C.A. now equals 2.5 x 400000, or Rs. 1000,000.

Computation of stock

Liquid ratio   = Liquid  assets/Current  liabilities

Or, 1.5 = (Current Assets - Stock )/400000

Or, 1.5  = (10,00, 000 - Stock)/4,00,000

1.5 *400000 = 1000000-Stock

600000 = 1000000- Stock

Therefore, stock = 100000-600000 = 400000

Computation of Proprietary fund; Fixed assets; Capital and Sundry payables (creditors)

Proprietors Fund divided by Permanent Assets equals Proprietors Fund.

Permanent assets therefore equal 0.75 proprietary fund, and

Net working capital  =  0.25 Proprietary fund

Therefore Proprietary fund = 600000/0.25

Proprietary fund = 24,00,0000 and  Fixed assets = 0.75 proprietary fund

= 0.75 of  24,00,000

Therefore, Fixed Assets = 18,00,000

Equity Capital = Proprietary fund - Reserves & Surplus

Therefore, Equity Capital = 2400000-400000

Equity Capital = 20,00,000

Variable payables (creditors) = (Current liabilities - Bank overdraft)

= (400000 - 100000) = 300000

Sundry payables = 300000

Net Current Assets =  (Current Assets - Stock) = 1000000-400000 = 600000

                                            Balance Sheet

Liabilities                      Amt in INR                         Assets              Amt in INR

What is plane?

In two dimensions, a plane can continue on forever. The lack of breadth. A plane is an example of coordinate geometry. A point's location in a plane is determined by its coordinates.

A plane is a two-dimensional, flat surface that never ends in mathematics. A plane is a two-dimensional equivalent of a three-dimensional equivalent that contains three spatial dimensions, a line, and a point. Planes can resemble subspaces in some higher-dimensional situations, as if the room's walls had been substantially stretched. These walls have their own existence, exactly as in the context of Euclidean geometry.

A flat surface in three dimensions can be represented using the plane equation. There are several approaches for determining the equation for a given function.. The equation for the plane can be expressed in either cartesian form or vector form.

Hence, the general form of the equation is A(x−x1)+B(y−y1)+C(z−z1)=0

Now,

y is a linear combination of a1 and a2 if it is in the plane, For the plane spanned by a1 and a2,

y = a a1 + b a2, a and b are constants here

[4,1,h] = [a - 2b,4a -3b,-2a+ 7b] Vectors are equal if their components are equal by the rules of vector addition and multiplication.

4 = a - 2b

1 = 4a - 3b

h = -2a + 7b

solve for a and b from the two equations for h:
