Sam says that 2/7 to the power of 2 times 1/3 to the power of 5 can be rewritten as 2/21 to the power of 7 sarah says it can be rewritten as 2/21 to the power of 10 steve says it cannot be rewritten as either of these expressions who is correct explain

the term to term rule is that every next term becomes 2 times of the previous term and the 11th term is 5120 for the sequence 5, 10, 20, 40, 80.

We have a sequence:

5, 10, 20, 40, 80

We need to find the term to term rule of the sequence.

We get that:

10 / 5 = 2

20 / 10 = 2

40 / 20 = 2

80 / 20 = 2

Term to term rule is that every next term becomes 2 times of the previous term.

10th term = 2560

11th term = 2 × 2560

11th term = 5120

Therefore, we get that, the term to term rule is that every next term becomes 2 times of the previous term and the 11th term is 5120 for the sequence 5, 10, 20, 40, 80.

You need to make 3 batches if you want to get 6 dozen cookies.

Here we know that you need to make a total of 6 dozen cookies, and we know that each batch you make gives 2 dozen.

Then if you make b batches, the number of dozens of cookies that you get is given by the linear equation:

d = 2*b

So, if you want to get 6 dozens, you need to replace d by 6, we will get:

6 = 2*b

Solving that for b, we get:

6/2  =b = 3

The value of the expression after rationalizing [tex]\frac{3+\sqrt{18} }{1+\sqrt{8} }[/tex] the denominator is [tex]\frac{3\sqrt{2}+9 }{7}[/tex].

A finite collection of symbols that is well-formed in accordance with context-dependent principles is referred to as an expression or mathematical expression.

Rationalizing the denominator is the process of shifting a root, such as a square root or a cube root, from the fraction's denominator to its numerator (numerator).

The numerator is the part of a fraction that comes before the vinculum.

The denominator of a fraction is the phrase that comes before the vinculum.

Consider the expression,

[tex]\frac{3+\sqrt{18} }{1+\sqrt{8} }[/tex]

Now, let [tex]y=\frac{3+\sqrt{18} }{1+\sqrt{8} }[/tex]

To rationalize the denominator we multiply and divide the expression by the conjugate 1 - √8.

[tex]y=\frac{3+\sqrt{18} }{1+\sqrt{8} } \times \frac{1-\sqrt{8} }{1-\sqrt{8} }[/tex]

[tex]y=\frac{(3+\sqrt{18})(1-\sqrt{8}) }{(1+\sqrt{8})(1-\sqrt{8}) }[/tex]

[tex]y=\frac{3-3\sqrt{8} +\sqrt{18}-(\sqrt{18} )(\sqrt{8} ) }{1-8}[/tex]

The inverse function returns the original value for which the output of a function was given.

The inverse of this function is [tex]f^{-1[/tex](x) = -(x - 4/3)

The inverse function returns the original value for which the output of a function was given. When it comes to functions, f and g are inverse, with f(g(x)) = g(f(x)) = x. A function that is made up of its inverse returns the original value.

A function's inverse is not always a function! To ensure that the inverse function is also a function, the original function must be a one-to-one function. A one-to-one function is one in which each second element corresponds to exactly one first element. (Each x and y value is only used once).

The inverse of a function is thought to be a reflection of the original function along the line y = x. Simply put; the inverse function is obtained by swapping the original function's (x, y) values.

Let the function be y = 4 - 3x

f(x) = 4 - 3x

y = 4 - 3x

simplifying the value of x, we get

x = 4 - 3y

x - 4 = -3y

x - 4/-3 = y

[tex]f^{-1[/tex]= - (x - 4/3)

The inverse of this function is [tex]f^{-1[/tex](x) = -(x - 4/3).

x = 15 , ∠ B = 108°

Step-by-step explanation:

∠ A and ∠ Bare alternate exterior angles and are congruent

∠ A = ∠ B , that is

6x + 18 = x + 93 ( subtract x from both sides )

5x + 18 = 93 ( subtract 18 from both sides )

5x = 75 ( divide both sides by 5 )

x = 15

Then

∠ B = x + 93 = 15 + 93 = 108°

Answer: Exercise 8 module 3 Describe the graph of the Celsius - Fahrenheit relationship is    F =  8C + 3  and     C = (F-3) / 8

Step-by-step explanation:

Celsius and Fahrenheit are two scales used to measure temperature. The temperature in the centigrade scale will be expressed in degrees Celsius. The temperature in the Fahrenheit scale will be expressed in degrees Fahrenheit. The relation between Celsius and Fahrenheit is proportional. Both have a different freezing point of water and both follow the varied unit difference between each scale.

Celsius to Fahrenheit

The conversion from Celsius to Fahrenheit can be mathematically expressed as-

                            F = [ (9/5) x C ] + 32

Where,

F is the temperature in Fahrenheit.

C is the temperature on the Centigrade scale.

Fahrenheit to Celsius

The conversion from Fahrenheit to Celsius can be mathematically expressed as-

                          C = (5/9) [ (F-32) ]

Where,

F is the temperature in Fahrenheit.

C is the temperature on the Centigrade scale.

Units of Celsius and Fahrenheit :

The units of temperature scale are useful in differentiating temperatures from one scale to another.

The temperature on the Celsius scale is denoted by °C

The temperature on the Fahrenheit scale is denoted by °F

Using linear function concepts, the graph of the Celsius-Fahrenheit relationship is linear with an intercept of 3 and slope of 8 module.

A linear function is modeled by:

                    y = mx + b

where,    m is the slope

so, we can write,

                    F =  8C + 3

we can also express the Celsius in terms of Fahrenheit :

                     8C = F - 3

                      C = (F-3) / 8

Therefore,

Exercise 8 module 3 Describe the graph of the Celsius - Fahrenheit relationship is    F =  8C + 3  and    C = (F-3) / 8.

The value of x for the equation 2 x=1/2 is 0.25

A linear equation with one variable is one that has just one variable. It has the formula Ax + B = 0, with A and B being any two real integers and x being an ambiguous variable with just one possible value. One such linear equation in one variable is 9x + 78 = 18.

One method for expressing a linear equation is in the slope-intercept form (the equation of a line). Y = mx+b, where m is the slope and b is the y-intercept, is the formula for the slope-intercept form (the point where the line crosses the y-axis). Using y=mx+b to graph a line is often simple.
