Answer:

  A)  6.86×10⁴

Step-by-step explanation:

You want to write 68600 in scientific notation.

The number 68600 can be written in expanded form with exponents as ...

  68600 = 6×10⁴ +8×10³ +6×10² +0×10¹ +0×10⁰

The left-most term of this sum tells you the exponent in scientific notation:

  68600 = 6.86×10⁴

Answer:

[tex]r > 2[/tex]

Step-by-step explanation:

1) Rearrange the terms

-6 > 10 - 8r

2) Calculate

8r > 10 + 6

3) Divide both sides

8r > 16

4) Simplify (Cross out the common factor)

[tex]r >[/tex] [tex]\frac{16}{8}[/tex]  

5) r > 2

Transformation of Reflect image over the y axis for this equation (x ,y)->(x +6,y -3)  is  (3, -1)

Reflecting point (-6,1) on y = x

gives (1, -6)

Translating, (1, -6) by 2,5 is

(1 + 2, - 6 + 5) = (3, - 1)

Therefore, reflect image over the y axis translate by rule (x ,y)->(x +6,y -3) is (3, - 1)

transformation :A function, f,  itself is called the transformation, i.e., f: X → X. After the transformation the pre-image X becomes the image X. This transformation can be any part or the mixture of operations such as translation, reflection, rotation and dilation. The translation is working a function in a particular direction, rotation is rotate the function to a point, reflection is the mirror image of the function, and dilation is the ascend of a function.

Translation, rotation, reflection, and dilation are the four most prevalent types of transformations. From the transformation, we have a rotation about any point, reflection over any line, and translation along any angle. The picture is congruent to its pre-image in these stiff transformations.. They are also called as isometric transformations. Dilation is performed at about any point of angle and it is non-isometric.

Rules for Transformations

Consider a function f(x). On a coordinate grid, we use the x-axis and y-axis to check the movement. Here are the rules for transformations of function that could be applied to the all graphs of functions. Transformations can be shown algebraically and graphically. Transformations are commonly found in algebraic functions. We can use the formula of transformations in graphical functions to obtain the graph just by transforming the fundamental or the parent function, and thereby move the graph around, rather than tabulating the coordinate values. We can visualize and learn algebraic equations with the aid of transformations.

Formula of Transformations

Let us consider the graph f(x) = [tex]x^{2}[/tex]

Suppose we have need to graph f(x) = [tex]x^{2}[/tex] -3, we shift the vertex 3 units down.

Suppose we have need to graph f(x) = 3 [tex]x^{2}[/tex]+ 2, we shift the vertex two units above and extend vertically by 3  factor

Suppose we have need to graph f(x) = 2(x-1)^2, we shift the vertex one unit to the right and extend vertically by 2  factor

Thus, we know the formula of transformations as

f(x) =a(bx-h) n + k

where k is the vertical shift,

h is the horizontal shift,

a is the vertical stretch and

b is the horizontal stretch

The expression which reflects the difference between the student's guess and the actual number of marbles is m-1206.

Given that there are 1206 marbles in the jar and student makes a guess of m marbles.

We are required to find the expression that represents the difference between the student's guess and the actual number of marbles.

Expression is the combination of numbers, symbols, fraction, coefficients and are found to be without the equal to sign.

Total number of marbles in the jar=1206

Number of marbles that student guesses=m

The expression that shows the difference between the student's guess and the actual number of marbles is m-1206.

Hence the expression which reflects the difference between the student's guess and the actual number of marbles is m-1206.

The circumference of the circle with radius 7 and value of pie 3, using the formula C= 2pie r is 42 unit.

Circumference of this circle using 3 for TT and 7 as radius.

The circumference of a circle is the distance around the outside of the circle. It is like the perimeter of other shapes like squares. You can think of it as the line that defines the shape. For shapes made of straight edges this line is called the perimeter but for circles this defining line is called the circumference. There are two other important distances on a circle, the radius (r) and the diameter (d). The radius, the diameter, and the circumference are the three defining aspects of every circle. Given the radius or diameter and pi you can calculate the circumference.

Circumference of circle = π x Diameter of circle.

You can also work out the circumference of a circle if you know its radius. Remember that the diameter is double the length of the radius. We already know that C = πd. If r is the radius of the circle, then d = 2r. So, C = 2πr.

Here, π = 3, r = 7,

So C = 2*7*3 = 42 units.

The amount of the total rent is 120 dollars.

Four students plan to rent a minivan for the weekend and equally share the rental cost.

By adding one more people, they can each save $6.

Therefore, the 4 students equally share the rent.

Hence,

average for 4 student = total amount shared / number of student

average for 4 student = x / 4

When you add one more person,

average for 5 student = x / 5

Therefore, the difference, will give you the total amount of the rent.

x / 4 - x / 5 = 6

5x - 4x/ 20 = 6

x / 20 = 6

cross multiply

x = 20 × 6

x = 120

Therefore, the amount of the total rent is 120 dollars.

The equivalent expression of the given expression is 5n/4 -3/8

What is Algebraic expression ?

Algebraic expressions are the idea of expressing numbers using letters or alphabets without specifying their actual values. The basics of algebra taught us how to express an unknown value using letters such as x, y, z, etc. These letters are called here as variables. An algebraic expression can be a combination of both variables and constants. Any value that is placed before and multiplied by a variable is a coefficient.

Here, the given expression is :

(-2 ¹/₂n + ¹/₄) + (3 ³/₄n - 5/8)

simplifying the above expression by taking like considering like terms :

= -2 ¹/₂n + 3 ³/₄n +  ¹/₄- 5/8

= (15/4)n - (5/2)n + (2-5)/8

= (15-10)n/4 -3/8

= 5n/4 -3/8

Step-by-step explanation:

1) Earth is 403,400,000 miles farther from Saturn than it is from Jupiter.

2) The total distance from Saturn to Jupiter and from Jupiter to Mars is 745,400,000 miles.

3) Saturn is 390,000,000 miles closer to Jupiter than is is to Earth.

4) Total distance from Mercury to Earth is 56,700,000 miles.

5) Venus is 22,300,000 miles closer to Earth than Mars.

6) Earth is 745,000,000 miles farther from Mars than Saturn.

Given,

1) Distance from Earth to Saturn = 793,000,000 miles

  Distance from Earth to Jupiter = 390,400,000 miles

793,000,000 - 390,400,000 = 403,400,000

That is, Earth is 403,400,000 miles farther from Saturn than it is from Jupiter.

2) Distance from Saturn to Jupiter = 403,400,000 miles

   Distance from Jupiter to Mars = 342,000,000 miles

403,400,000 + 342,000,000 = 745,400,000

Therefore, the total distance from Saturn to Jupiter and from Jupiter to Mars is 745,400,000 miles.

3) Distance from Saturn to Jupiter = 403,400,000 miles

   Distance from Saturn to Earth = 793,800,000 miles

793,800,000 - 403,400,000 = 390,400,000

So, Saturn is 390,000,000 miles closer to Jupiter than is is to Earth.

4) Distance from Mercury to Venus = 30,700,000 miles

   Distance from Venus to Earth = 26,000,000 miles

30,700,000 + 26,000,000 = 56,700,000

That is, the total distance from Mercury to Earth is 56,700,000 miles.

5) Distance from Earth to Venus = 26,000,000 miles

   Distance from Earth to Mars = 48,300,000 miles

48,300,000 - 26,000,000 = 22,300,000

That is, Venus is 22,300,000 miles closer to Earth than Mars.

6) Distance from Earth to Saturn = 793,800,000 miles

   Distance from Earth to Mars = 48,300,000 miles

793,800,000 - 48,300,000 = 745,500,000

That is, Earth is 745,000,000 miles farther from Mars than Saturn.

Mediante la ley del seno, la longitud del faro es aproximadamente igual a 8.295 metros.

En esta pregunta nos encontramos con una sistema geométrico con dos ángulos y un lado conocidos, la configuración permite determinar la altura del faro mediante la ley del seno, cuya expresión sería la siguiente:

AC / sin B = AB / sin C = BC / sin A      

Donde BC es la longitud del faro, medida en metros, y AC es la distancia horizontal hasta la base del faro, medida en metros. Si sabemos que AC = 9.9 m, B = 53° and A = 42°, entonces la longitud del faro es:

(9.9 m) / sin 53° = BC / sin 42°

BC = 9.9 m × (sin 42° / sin 53°)

BC ≈ 8.295 m
