The perfect square equation is f(x) = (x + 7/2)^2 - 9/4

The equation of the function is given as

f(x) = x^2 + 7x + 10

Rewrite the equation as

x^2 + 7x + 10 = 0

Subtract 10 from both sides of the equation

So, we have

x^2 + 7x = -10

-----------------------------------------------------------------------

Take the coefficient of x

k = 7

Divide by 2

k/2 = 7/2

Square both sides

(k/2) = 49/4

-----------------------------------------------------------------------

Add 49/4 to both sides of the equation

So, we have

x^2 + 7x + 49/4 = -10 + 49/4

Express as a perfect square

So, we have

(x + 7/2)^2 = -10 + 49/4

Evaluate the sum

So, we have

(x + 7/2)^2 = 9/4

This gives

(x + 7/2)^2 - 9/4 = 0

So, we have

f(x) = (x + 7/2)^2 - 9/4

Hence, the perfect square equation is f(x) = (x + 7/2)^2 - 9/4

The missing 2nd term of the given arithmetic sequence 25, _, 53,...(a₂ = 39).

The difference between the two different numerical orders is a fixed number in Arithmetic Progression (AP). Another name for it is Arithmetic Sequence.

We'd come along through a few specific words in AP that were labeled as:

The AP can also be understood in terms of common differences, as shown below.

Now, for the given AP;   25, _, 53....

Let the initial term be 'a₁' = 25

Let the second term be 'a₂' = ?

Let the third term be 'a₃' = 53.

The AP must have the same common difference. So,

d =  a₂ - a₁ or d = a₃ - a₂

Equating the common difference to find the 2nd missing term.

a₃ - a₂ = a₂ - a₁

Substitute the given values;

53 - a₂ = a₂ - 25

Bring the variable part on one side.

2a₂ = 53 + 25

a₂ = 78/2

a₂ = 39

Therefore, the 2nd missing value of an AP is found to be 39.

Answer:

x² + [tex]\frac{1}{x^2}[/tex] = 5

Step-by-step explanation:

using the identity

(a - b)² = a² + b² - 2ab , then given

(x - [tex]\frac{1}{x}[/tex] ) = [tex]\sqrt{3}[/tex] ( square both sides )

(x - [tex]\frac{1}{x}[/tex] )² = ([tex]\sqrt{3}[/tex] )² , that is using the above identity

x² + [tex]\frac{1}{x^2}[/tex] - 2(x × [tex]\frac{1}{x}[/tex] ) = 3

x² + [tex]\frac{1}{x^2}[/tex] - 2(1) = 3

x² + [tex]\frac{1}{x^2}[/tex] - 2 = 3 ( add 2 to both sides )

x² + [tex]\frac{1}{x^2}[/tex] = 5

[tex]\displaystyle\\Answer:\ x^2+\frac{1}{x^2}=5[/tex]

What is the constant of proportion?

A constant of proportion is illustrated as the ratio which relates two given quantities with each other in the relationship of proportion. Constant of proportion is also called constant variation, rate of change, and constant ratio.

Solving for the value of y

let k be the constant of proportion

When a quantity varies directly with others, then we have a relation, y = kx      —-- 1

Now, find k for given x = 3 / 4 and y = 5 / 3, we need to put these values in equation 1, i.e.

5 / 3 = k(3 / 4)

k = (5 × 4) / 9

k = 20 / 9

Further calculate x for given y = ½ and constant of proportion = 20/9i.e.

½ = (20 / 9)x

x = 9 / 40

Hence, the required value of x is 9 / 40.

Answer:

7.50c+12a<or=200 (you would have a inequality since that is the maximum number you could pay and no other information is given)

the graph is above and the inequality in slop intercept format is y= -5/8x+ 16 2/3

Solutions for c: 0 <or= c <or= 26* *(since that is the maximum whole number you can have for $200)

Solutions for a: 0 <or= a <or= 16* *(since that is the maximum whole number you can have for $200)

Note: In order for find other solutions your cordatnate has to be a whole number (that is positive or zero) within the red area shaded. However there are many examples given for answer purposes.

Step-by-step explanation:

$7.50 is the price of each children tickets and $12 is the price of each adult tickets and when combined equal to $200 so you can multiply the variables to get 7.5c+12a <or= 200.

To graph the inequality there's two ways;

Way 1: Change from standerd form to slope intercept form

Way 2: Isolate your variables to get your x and y intercept

The interval of x-values over which the function is decreasing is ( - 1,1).

In mathematics, a polynomial is an expression that solely uses the operations of multiplication, addition, subtraction, and non-negative integer exponentiation of variables. It is made up of coefficients and indeterminates.

By differentiating the given function, it is possible to find the range of x-values across which the provided function is decreasing: (-1,1).

Given function is , f(x) = x³ – 3x – 2.

The following steps can be used in order to determine the interval in which the given function is decreasing:-

Step 1 - Write the given function.

f(x) = x³ – 3x – 2.

Step 2 - Now, differentiate the above function with respect to 'x'.

F'(x) = 3x² - 3

Step 3 - Now, equate the above expression to zero.

x² = 1

x = 1 or -1

The solution of the given equation 5-4t = 12 is at t = -7/4.

According to the given question.

We have a linear equation in one variable.

5 - 4t = 12

As we know that, linear equation in one variable is an equation which is expressed in the form of ax+b = 0, where a and b are two integers, and x is a variable and has only one solution.

Thereofre, th esolution for the given equation 5 - 4t = 12 is given by

5 - 4t = 12

⇒ -4t = 12 - 5      (subtracting 5 from both the sides)
