How do you construct a perpendicular bisector of Class 9?

Answer: the total spent on the meal is $88.25875.

Step-by-step explanation:

The total spent on the meal can be calculated by adding the cost of the meal, the tax, and the tip.

First, we need to calculate the cost of the tax: 72.5 x 0.0675 = 4.88375

Then we need to calculate the cost of the tip: 72.5 x 0.15 = 10.875

Finally, we add the cost of the meal (72.5), the tax (4.88375) and the tip (10.875) to find the total cost of the meal: 72.5 + 4.88375 + 10.875 = 88.25875

Therefore, the total spent on the meal is $88.25875.

Answer:

  (c)  3x√(6x) -x⁴√(30x) +24x²√2 -8x⁵√10

Step-by-step explanation:

You want to simplify the product ...

  [tex](\sqrt{6x^2}+4\sqrt{8x^3})(\sqrt{9x}-x\sqrt{5x^5})[/tex]

As with a lot of problems of this type, the correct answer choice can be selected by examining a term or two.

Multiplying the last two terms of the binomials, we get ...

  [tex]4\sqrt{8x^3}\cdot (-x\sqrt{5x^5})=-4x\sqrt{40x^8}=-4x\sqrt{10(2x^4)^2}=\boxed{-8x^5\sqrt{10}}[/tex]

This term is only found in choice C.

Additional comment

The expression is simplified by making use of the radical relations ...

  (√a)(√b) = √(ab)

  √(a²b) = a√b

The given expression can be rewritten with squares taken out of the radicals as ...

  (x√6 +8x√(2x))·(3√x -x³√(5x))

Then, using FOIL or the distributive property, we have ...

  = 3x√(6x) +24x²√2 -x⁴√(30x) -8x⁵√10 . . . . . matches C

The required two-column proof that the triangles are congruent is explained below.

A triangle is a three sided plane shape whose the sum of internal angles is 180^o. Thus two or more triangles are said to be congruent when their corresponding sides and measure of internal angles are equal.

When two triangles are congruent, it can be proven in all respect that they are thus equal (considering their corresponding length of sides and measure of internal angles).

Answer:

10 and 16

Step-by-step explanation:

let on number be x then the other number is x + 6

sum the 2 numbers and equate to 26

x + x + 6 = 26

2x + 6 = 26 ( subtract 6 from both sides )

2x = 20 ( divide both sides by 2 )

x = 10

x + 6 = 10 + 6 = 16

No, Eric will not have enough banana bread to serve all 20 guests if he bakes only 3 loaves.

Eric is making banana bread to serve 20 guests, and he wants each guest to have 1/6 of a loaf. This means that each loaf will be divided into 6 equal portions, and each guest will receive one of these portions.

Eric plans to bake 3 loaves of banana bread. As 1 loaf can serve 6 guests with 3 loaves he can serve a total of

3×6 = 18 < 20

So only 18 guests can be served with 3 loaves of bread.

The product of two complex numbers, with a result of 821, is given as follows:

(26 + 12.04i)(26 - 12.04i) = 821.

Complex numbers are numbers that are composed by a real part and by an imaginary part, and have the notation given as follows:

z = a + bi.

In which:

The most important complex numbers relation is given as follows:

i² = -1.

Meaning that the easiest way to obtain the desired product is multiplying complex-conjugate numbers, as follows:

(a + bi)(a - bi).

Applying the subtraction of perfect squares, we have that:

(a + bi)(a - bi) = a² - (bi)²

(a + bi)(a - bi) = a² - b²i²

(a + bi)(a - bi) = a² + b² (as i² = -1).

Then, attributing a = 26, the value of b is obtained as follows:

a² + b² = 821

26² + b² = 821

[tex]b = \sqrt{821 - 26^2}[/tex]

b = 12.04.

When an image is enlarged using a scale factor between 1 and 1, the image does not change in size.

A scale factor of 1 means that the image is not being enlarged or reduced in size; it is remaining the same size. Therefore, the image will appear the same as it did before the enlargement.

A scale factor of less than 1 means that the image is being reduced in size, and a scale factor greater than 1 means that the image is being enlarged in size. But when it comes to scale factor between 1 and 1, the image will not change in size, it will appear the same as it was before.

It's important to note that when you're enlarging an image using a scale factor that's less than 1, the image becomes smaller but when you're using a scale factor greater than 1 the image becomes larger.

By solving the given inequality in question, i.e -8+2x>4 , the solution obtained is x>6, which means the inequality satisfies for all the values of x that are greater than 6.

An inequality is a statement that compares two values and asserts that one value is greater than, less than, or not equal to the other value. Inequalities are used to describe a range of values that a variable can take on. The most common symbols used to express inequalities are ">", "<", "≥" and "≤", which represent "greater than", "less than", "greater than or equal to" and "less than or equal to" respectively.

An example for inequality can be , the inequality x > 2 , which states that x is greater than 2, which means that any value of x that is greater than 2 satisfies the inequality.

Inequality can be solved either graphically or algebraically. The solution of an inequality is the set of all values that make the inequality true.

To solve the inequality -8 + 2x > 4, you can follow these steps:

So the solution of the inequality is x > 6.

This means that x is greater than 6. So any value of x that is greater than 6 satisfies the inequality.

A substitution reaction is a reaction in which one group of molecules gets replaced by another group of molecules in an aqueous medium.

The substitution reactions are classified into three groups,

In the nucleophilic reactions the atom is said to be rich in electron , whereas, in the electrophilic reaction, the atom is known to be  an electron-deficient species.

The primary difference between substitution and elimination reactions is that substitution reactions replace one group with another, whereas elimination reactions merely remove the group. The main distinction between the groups is the number of stages involved in the reaction.

The antithesis of an exponential function is a logarithmic function. A logarithmic function and an exponential function both use the same base.

Writing y = log2 x or f(x) = log2 x represents the logarithmic function for the equation x = 2y. Even today, the base is still 2. Y equals log base b of x, or more simply, "y equals log to the base b of x," is how y = logb x is typically read. Similarly to exponential functions, b > 0 and b 1.

Consequently, the table's data is represented by the logarithmic function f(x) = log3(x).

Table provided:

                    x           f(x)

                    25          2

                   125          3

                   625         4

[tex]$25=5^2$$125=5^3$$625=5^4$$\Rightarrow f(x)=5^{f(x)}$[/tex]

In mathematics, a differential equation is an equation involving one or more functions and their derivatives. The derivative of a function defines the rate of change of the function at some point.

According to the given Question:

Differential equation:

In mathematics, a differential equation is an equation that relates one or more unknown functions and their derivatives.  In applications, a function generally represents a physical quantity, a derivative its rate of change, and a differential equation defines the relationship between the two. Such relationships are common. Therefore, differential equations play an important role in many fields such as engineering, physics, economics and biology.

The study of differential equations consists primarily of studying their solutions (the set of functions that satisfy each equation) and the properties of those solutions. Only the simplest differential equations can be solved with explicit formulas. However, many properties of solutions to particular differential equations can be determined without exact computation. In many cases, when a closed formula for the solution is not available, the solution can be approximated numerically using a computer. Although the theory of dynamical systems focuses on qualitative analysis of systems described by differential equations, many numerical methods have been developed to determine solutions with some degree of accuracy.

A first-order linear differential equation is an equation that can be written in the form y0 + p(x)y = q(x). where p and q are continuous functions on the interval I. The second-order linear differential equation has a similar form.
