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]

[tex]y=\frac{3-6\sqrt{2}+3\sqrt{2}-(3\sqrt{2})(2\sqrt{2}) }{-7}[/tex]

[tex]y=\frac{3-3\sqrt{2}-12 }{-7}[/tex]

[tex]y=\frac{-3\sqrt{2}-9 }{-7}[/tex]

[tex]y=\frac{3\sqrt{2} +9}{7}[/tex]

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

1) the mathematical model for given situation is f(t) = 2t + t, where t is the time in minutes

2) the amount of water in the pool after 50 minutes = 105 gallons

3) and the amount of time required to fill the pool =  12 hours 46 minutes

In this question,

a small pool hold 1500 gallons of water.

When there's is 5 gallons of water in the pool, the person decided

that not to stand outside and watch the pool fill.

This means, from the time he had decided, the amount of water in the pool = 5 gallons.

the water was filling the pool at a rate of 2.

Let t be the time in minutes.

So, the amount of water in the pool after 't' minutes would be,

f(t) = 2t + 5

We get an mathematical model for given situation,

f(t) = 2t + 5, where t is the time in minutes

We need to find the amount of water in the pool after 50 minutes

For t = 50 minutes

f(50) = 2(50) + 5

f(50) = 100 + 5

f(50) = 105 gallons

Also, we need to find the amount of time required to fill the pool.

1500 = 2t + 5

1495 = 2t

t = 747.5 minutes

t = 12 hours 46 minutes

Therefore, 1) the mathematical model for given situation is f(t) = 2t + t, where t is the time in minutes

2) the amount of water in the pool after 50 minutes = 105 gallons

Answer:

The solution to this equation is (9t)^(12) / (4a)^(6).

Step-by-step explanation:

It is given that [(4a³t²)/(9at^6)]^-3 which is to be simplified and solved to get the final answer.

Now,

let us have a look at the equation and observe the powers given;

=> [(4a³t²)/(9at^6)]^-3

So, let us convert the powers using the rules;

=> [(4a²)/(9t^4)]^-3

Further, we will apply the rule known as product of powers and we get an equation that is;

=> (4a)^(-6) / (9t)^(-12)

Now, after reciprocating both the powers as per the rules we get;

=> (9t)^(12) / (4a)^(6)

Therefore, the solution to this equation is (9t)^(12) / (4a)^(6).

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).

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°

The solution for equation ln (3 x+5)²=4 is 0.796.

ln (3 x+5)²=4

3x = 7.389-5

x = 0.796

A formula would be 3x - 5 = 16, for instance. When this equation is solved, we discover that the value of the variable x is 7.

The g function can be obtained from the graph using two points, the first (0,6) and the second (2,0).

Remember, a line has the following equation:

y=mx=b, where 'm' is the slope and 'b' the interception with 'y' axis

b=6, since x=0 and y=6.

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.
