The value of the expression [tex]\frac{2+\sqrt{5} }{\sqrt{5} }[/tex] after rationalizing the denominator is [tex]\frac{2\sqrt{5}+5 }{5}[/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{2+\sqrt{5} }{\sqrt{5} }[/tex]

Now, let [tex]y=\frac{2+\sqrt{5} }{\sqrt{5} }[/tex]

To rationalize the denominator we multiply and divide the expression by √5.

[tex]y=\frac{2+\sqrt{5} }{\sqrt{5} } \times \frac{\sqrt{5} }{\sqrt{5} }[/tex]

[tex]y=\frac{2\sqrt{5}+(\sqrt{5} )^{2} }{(\sqrt{5} )^{2}}[/tex]

[tex]y=\frac{2\sqrt{5}+5 }{5}[/tex]

The value of the expression when rationalized [tex]\frac{2+\sqrt{5} }{\sqrt{5} }[/tex] is [tex]\frac{2\sqrt{5}+5 }{5}[/tex].

The number of adult tickets sold for $50 is 990 and the number of children tickets sold for $10 is  450

How do we represent adult tickets and children's tickets?

The adult tickets can be represented by x whereas the children's tickets are represented by y, hence, the sum of x and y gives 1440 tickets

x+y=1440.......... equation 1

50x+10y=54000........ equation 2

solve for x in equation 1

x=1440-y

substitute for x in equation 2

50(1440-y)+10y=54000

72000-50y+10y=54000

72000-54000=50y-10y

18000=40y

y=18000/40

y=450

x+y=1440

x+450=1440

x=1440-450

Answer:

Below in bold.

Step-by-step explanation:

f(x)=1.8x^2-6.2x+2.5

As the coefficient of x^2 is positive this has a minimum value.

Find the derivative:

f'(x) = 3.6x - 6.2

This = 0 for a minimum value of f(x):

3.6x - 6.2 = 0

x = 6.2/3.6 = 1.722

This is the value of x when f(x) is a minimum.

So, the minimum value of f(x)

= 1.8(1.722)^2 - 6.2*1.722 + 2.5

= -2.838......

= -2.84 to nearest hundredth.

The area and perimeter of the triangle are:

B. 12x; 5x + 14

The area of the triangle in the image is calculated using the formula, area = 1/2(b)(h), where:

Substitute

Area of the triangle = 1/2(8)(3x)

Area of the triangle = 4(3x)

Area of the triangle = 12x units²

The perimeter of the triangle in the image is calculated by adding the length of all three sides of the triangle, which is:

Perimeter = (x + 9) + 8 + (4x - 3)

Perimeter = x + 9 + 8 + 4x - 3

Applying the rules of addition and scalar multiplication of vectors, –4w = (–8, 20) and –4u + w = (6, –7)

In the 2D coordinate system, vectors can be split into x-component and y-component.

we can write, for example, a vector r = (2,–6), which means:

x-component = 2

y-component = –6

In the given problem:

u = (-1,3), v = ( 2,4) , and w = (2,-5)

Then,

–4w =  –4(2, –5)

       = (–4 . 2, –4. (–5)) = (–8, 20)

–4u + w =  –4(-1,3) + (2, –5)

So, we have

r = 16/2

Evaluate the quotient

r = 8

The circumference of the circle is then calculated as

C = 2πr

Where π is given as

π = 3.14

So, we have

C = 2 * 3.14 * 8

Expanded form of logarithm  log√x²-4 / (x+3)² is 1/2log(x²-4)-2log (x+3).

By considering the given logarithm function

log√x²-4 / (x+3)²

log√x²-4 -log (x+3)²

1/2log(x²-4)-2log (x+3)

The logarithm is exponentiation's opposite function in mathematics. This means that the exponent to which a fixed number, base b, must be raised in order to produce a given number x, is represented by the logarithm of that number.

Based on the logarithm base, the logarithmic functions are broadly divided into two types. There are common and natural logarithms. Common logarithms are based on the number 10, while natural logarithms are based on the base "e." The power to which a number must be raised in order to obtain another number is known as a logarithm (see Section 3 of this Math Review for more about exponents).

Answer: (^ represents the exponent)

a) 10^x-1

b) 10^4x

c) c^6

Step-by-step explanation:

a) When you divide powers, you subtract their exponents. Since c = 10^x and it is being divided by 10^1, it would be the equivalent of 10^x-1

b) c= 10^x. c^4 would be equal to (10^x)^4 or [tex](10^{x})^{4}[/tex]. When powers are placed this way, you multiply their exponents. For instance [tex](3^{2})^{4}[/tex] would be [tex]3^{8}[/tex].

C) This is the same concept as part b, but reversed. 10^6x is equal to (10^x)^6, which is equal to c^6.

The functions that model the two discounts will be given as R (x) = 5 x and M (y) = 0.15 y.

We are given that:

Rebate a customer receives if he buys a regular priced CD at $ 13 each = $ 5.

If a customer registers for the store member, he get a discount = 15 %.

Now, let the regular priced CD purchased be x and the application for store member be y.

So, the functions will become:

For rebate:

R (x) = 5 x

For discount:

M (y) = 15 % of x

M (y) = 0.15 x

Therefore, we get that, the functions that model the two discounts will be given as R (x) = 5 x and M (y) = 0.15 y.

No , investing $ 2000 in an account that pays 5% annual interest compounded continuously is not same as investing $ 1000 at 4 % and $ 1000 at 6% .
