Given that

To find

So, according to the question

We have

A square root can only be calculated in values equal to or greater than zero, so keep that in mind.

So, if we want the domain to be x > 5, then we must have:

[tex]\sqrt{x-5}[/tex].

Now that we also want the range to be equal to or less than 3, we need a constant term with a value of 3 and a negative coefficient before the square root, which gives us:

y = - [tex]\sqrt{x-5}[/tex] +3

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.

Step-by-step explanation:

The completely factorised form of the expression given in the task content as given is; (3x +6) (x+b).

In order words, when the above given polynomial expression is being factorized, it gives (3x +6) (x+b) as its complete factorized form.

It follows from the task content that the expression which is required to be factorized completely is given below as;

3x² + 3bx + 6a + 6b

So therefore, the mathematics expression can be factored completely as follows step by step:

(3x² + 3bx) + (6x + 6b)

3x(x + b) + 6(x+b)

Ultimately, the completely factorized form of the mathematical expression as indicated in the given expression above is therefore represented as thus;

The perimeter of a trapezoid is All the sides combined. We already know two of the sides. You can simplify the square roots to be 2[tex]\sqrt{2}[/tex]+6+x. We know that two sides (or the ones we don't know) are equal, and we see an altitude. This shows that we can make a right triangle be a^2+b^2=c^2. Once we substitute everything, we find [tex]2\sqrt{2}[/tex]^2(or 8)+x^2+c^2. This means that we now need to find x.

The exponential function that models exponential growth is y = 5(3)ˣ.

The example of an exponential function that models exponential decay is y = 2(0.8)ˣ

Exponential growth is the process by which quantity increases over time. It happens whenever the instantaneous rate of change of a volume with respect to time has been proportional to the volume itself.

Consider exponential function; y = a(b)ˣ.

For the exponential growth a > 0 and b > 0.

Suppose a = 5 and b = 3.

Then, the function will become after substituting the both values.

y = 5(3)ˣ which is the exponential growth of the exponential function.

According to the law, exponential decay would be the decrease in a quantity (1) where is the exponential function and the initial value, for a parameter as well as constant (known as the decay constant).

Now, as per the question.

For the exponential decay a > 0 only.

Consider exponential function; y = a(b)ˣ.

Let, a = 2 and b = 0.8.

Then,

y = 2(0.8)ˣ

Therefore, the exponential function in the form of exponential decay is y = 2(0.8)ˣ.

Answer:

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.

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]
