earth's equator has a diamter of 7926.4 miles. which equation can be used to find the circumference of earth at the equator?

Answers

Answer 1

Answer:

To find the circumference you need to use C= 2πr but since you started with the diameter you need to divide it by 2 and you will get 3963.2. After you get the radius use the formula C= 2πr and you will get 24901.52

The equation would be written as 2 x π x 3963.2 = 24901.52

Step-by-step explanation:

Given g(x) then g(x) + c is a vertical translation of g(x)

• If c > 0 then a shift up of c units

• If c < 0 then a shift down of c units

Thus g(x) is the graph of f(x) translated 5 units up

Set up a proportion.

The total side of the “top” line is 8 + 10 = 18. The total side of the “bottom” line is 45. This makes the ratio 18/45.

Now we are trying to find the “larger” bottom segment, let it be x. Because the lines are parallel, the ratio of the “larger” top and bottom segments is equal to the ratio of the whole top and bottom lines.

So 18/45 = 10/x

Reduce 2/5 = 10/x

Cross multiply 2x = 50

Solve x = 25

Can u plz mark me branliest plz.

Answer:

p = 50

Step-by-step explanation:

[tex]\frac{1}{2} *p+75=100\\[/tex]

Combine like terms into a single fraction:

[tex]\frac{1}{2} p+75=100[/tex]

[tex]\frac{1p}{2} +75=100[/tex]

Multiply by 1:

[tex]\frac{1p}{2}+75=100[/tex]

[tex]\frac{p}{2} +75=100[/tex]

Subtract 75 from both sides of the equation:

[tex]\frac{p}{2} +75=100[/tex]

[tex]\frac{p}{2} +75-75=100-75[/tex]

Simplify:

Subtract the numbers:

[tex]\frac{p}{2} +75-75=100-75[/tex]

[tex]\frac{p}{2} =100-75[/tex]

Subtract the numbers:

[tex]\frac{p}{2} =100-75[/tex]

[tex]\frac{p}{2} =25[/tex]

Multiply all terms by the same value to eliminate fraction denominators:

[tex]\frac{p}{2} =25[/tex]

[tex]2*\frac{p}{2} =2*25[/tex]

Simplify:

[tex]2*\frac{p}{2} =2*25[/tex]

[tex]p=2*25[/tex]

Multiply the numbers:

[tex]p=2*25[/tex]

[tex]p=50[/tex]

Solution:

[tex]p=50[/tex]

Perimeter (P)

= 1600 cm

For 13

Area

= L * B

= 500 * 300

= 150000 cm²

Step-by-step explanation:

Since Promethean board is rectangle in shape,

So Given,

Dimensions of that board = 500 cm by 300 cm

Hence, Perimeter of the board = 2(l+b)

= 2(500cm + 300cm) = 2 × 800cm

= 1600cm (Ans)(i)

Therefore, area of that board = l × b

Step-by-step explanation:

A quadratic expression is an expression involving a squared term

It can be written as y = a[tex]x^{2}[/tex] + bx + c, where a ≠ 0

// note that here b and c can be equal to 0

1) 6[tex]x^{4}[/tex] - 5[tex]x^{3}[/tex]  + 3[tex]x^{2}[/tex]  - 7x - 8 is simply incorrect because you can't write in the previously mentioned form. It is a quartic function, since the unknown variable x in forth degree. It can be written as y = a[tex]x^{4}[/tex] +b[tex]x^{3}[/tex] +c[tex]x^{2}[/tex] + dx + e, where a before [tex]x^{4}[/tex] ≠ 0

2) 5[tex]x^{3}[/tex]  + 3[tex]x^{2}[/tex]  - 7x - 8 is simply incorrect because you can't write in the previously mentioned form. It is a cubic function, since the unknown variable x in third degree.

3) 2[tex]x^{2}[/tex] + 3x - 1 is correct

4) 3x - 1 is incorrect because there is no squared term. You could also say that here a = 0 and write it as y = 0 * [tex]x^{2}[/tex]  + 3x - 1. It is also called a linear function because if you'd draw a graph, it would be a line

Answer:

Area = 113.01 m²

Step-by-step explanation:

From the picture attached,

Area of the quadrilateral ABCD = Area of triangle ABC+ Area of triangle ACD

Construction to be done → Draw a perpendicular from a point A to the opposite side CD

Area of Δ ABC = [tex]\frac{1}{2}(AB)(BC)[/tex]

                         = [tex]\frac{1}{2}(12)(10)[/tex]

                         = 60 m²

Area of triangle ACD = [tex]\frac{1}{2}(AE)(CD)[/tex]

From ΔAEC,

sin(29°) = [tex]\frac{AE}{AC}[/tex]

AC = [tex]\sqrt{(12)^2+(10)^2}[/tex] [By Pythagoras theorem]

AC = [tex]\sqrt{244}[/tex]

AC = 15.62 m

Therefore, AE = 15.62sin(29)

                        = 7.57 m

Area of ΔACD = [tex]\frac{1}{2}(7.57)(14)[/tex]

                        = 53.01 m²                                

Area of ABCD = 60 + 53.01

                        = 113.01 m²            

7(x-2)=28 Can somebody help me and show the steps?

Answers

Since the 7 is in front of the parentheses you must multiply it by everything inside the parentheses. 7 times X is 7X and 7 times -2 is -14. Then you need to make the X be by itself on one side, to do that you have to add 14 to -14 to make it disappear, and also add 14 to the other side, to 28. Then you divide both sides by 7 to make X be by itself.

7(x-2)=28
7X-14=28
7x=42
X=6

The product of

integers?

Answers

Answer:

a= 12

b=-2

Step-by-step explanation:

12 x -2 = -24

12 - (-2) = 14

12 + (-2) = 10

The two integers are 12 and -2.

What are simultaneous equation?

In mathematics, a set of simultaneous equations, also known as a system of equations or an equation system, is a finite set of equations for which common solutions are sought.

Let x and y be the two integers.

So it is given that,

Product of two integers =  – 24

⇒ xy = - 24   ....(i)

The difference between the two integers =  14

⇒ x - y = 14  ...(ii)

The sum of the two integers = 10

⇒ x + y = 10     ....(iii)

Now adding equation (ii) and (iii) we get,

2x = 24

⇒ x = 12

Putting the value of x in equation (i) we get,

12y = - 24

⇒ y = - 2

So the required integers are 12 and - 2.

Which equation could represent a vertical asymptote of the graph of the function?

O y = 0
Ox= -1
O y=-1

Answer:

X=-1

Step-by-step explanation:

The correct equation could represent a vertical asymptote of the graph of the function is,

⇒ x = -1

What is mean by Function?

A relation between a set of inputs having one output each is called a function. and an expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable (the dependent variable).

Now, According to the given table, we see that for x = -1, the function is not defined, that means that the rational function has a restriction there, and such restriction is shown as an asymptote in the graph of the function.

So, basically, we could say that the given rational function has one asymptote and it's at x = -1, which is a vertical asymptote, because all forms like x = k, are vertical lines, that is, they are parallel to the vertical axis.

Therefore, The correct equation could represent a vertical asymptote of the graph of the function is,

⇒ x = -1
