Answer:

Option D: y = (∛x + 3) + 3

Step-by-step explanation:

To solve this, let's plug in some values into each of the options given.

From the graph, we can see that when x = 0, y ≈ 4.45.

Thus,let's plug in 0 for x into each of the options;

A) y = (√x - 3) + 3

Put 0 for x into the equation.

y = (√0 - 3) + 3

y = (√-3) + 3

Thus will give us a complex root. Thus, it is not the correct answer.

B) y = (√x + 3) + 3

Put 0 for x into the equation.

y = (√0 + 3) + 3

y = (√3) + 3

y = 1.732 + 3

y = 4.732

Thus,this function is not the correct answer.

C) y = (∛x - 3) + 3

Put 0 for x into the equation

y = (∛0 - 3) + 3

y = (∛-3) + 3

y = -1 + 3

y = 2

y is not equal to 4.45 and thus the function is not correct

D) y = (∛x + 3) + 3

Put 0 for x into the equation

y = (∛0 + 3) + 3

y = (∛3) + 3

y = 1.44 + 3

y = 4.44

This is approximately equal to the approximate value of 4.45 on the graph. Thus, it's the correct function.

Answer: I got 18

Step-by-step explanation:

Substitute all the variables

18 = 2*3^2

X = 4 * 9^2

X = 4 * 81

X = 324

324/18 = 18

so the is answer is 18.

So the maximum number of edges in an undirected graph with 100 vertices is 4950.

In an undirected graph, each edge connects two vertices, and as such, it is counted twice, once for each vertex it connects. Therefore, the total number of edges in the graph is the sum of the degrees of all vertices, divided by 2.

In a complete graph with n vertices, every vertex is connected to every other vertex, except itself, and so the degree of each vertex is n-1 (it is connected to n-1 other vertices). Therefore, the total number of edges in the graph is:

n * (n-1) / 2

Substituting n = 100, we get:

100 * 99 / 2 = 4950

16. The value of y in 2y + 7x = 4 is -15.5.

18. The value of y in 6x = 7 - 4y is 4.75.

Expression simply refers to the mathematical statements which have at least two terms which are related by an operator and contain either numbers, variables, or both.

16. In this case, 2y + 7x = 4

when x = 5, y will be:

2y + 7x = 4

2y + 7(5) = 4

2y + 35 = 4

Collect like terms

2y = 4 - 35.

2y = -31

y = -31/2

y = -15.5

18. 6x = 7 - 4y.

To determine if two functions are inverses, we have to compose the functions into each other and get a value of x.

f(g(x)) = \(3(\sqrt{\frac{x - 12}{3} })^{2} - 12\)

The square root and the square cancel each other out.

f(g(x)) = \(3(\frac{x - 12}{3}) - 12\)

The 3's cancel each other out.

f(g(x)) = x - 12 - 12 = x - 24

since f(g(x)) = x - 24, these two functions are not inverses of each other.

x=√(141)

that is the answer

Answer:

x = \(\sqrt{141}\)

Step-by-step explanation:

Using Pythagoras' identity in the right triangle.

The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is

x² + 22² = 25²

x² + 484 = 625 ( subtract 484 from both sides )

x² = 141 ( take square root of both sides )

x = \(\sqrt{141}\)

The value of the variable x for the function f(x) = x² + 4x for which

f(f(x) ) = f(x) is equal to x = -1 or x = -3.

The function f(x) = x² + 4x

Substitute the value in the required function we get,

Right hand side

= f ( f(x))

= f ( x² + 4x )

= ( x² + 4x )² + 4 ( x² + 4x )

= x⁴ + 8x³ + 16x² + 4x² + 16x

= x⁴ + 8x³ + 20x² + 16x

Left hand side

f(x)

= x² + 4x

Equate left hand side is equal to right hand side we get,

x⁴ + 8x³ + 20x² + 16x = x² + 4x

⇒x⁴ + 4x³ + 4x³ + 16x² + 4x² + 16x =  x² + 4x

⇒x² ( x² +4x ) + 4x ( x² + 4x )+ 4 ( x² + 4x ) = x² + 4x

⇒( x² + 4x ) ( x² + 4x + 4 ) = x² + 4x

⇒ x² + 4x + 4 = 1

⇒ ( x + 2 )²  - 1² =0

⇒ ( x + 2 -1 ) ( x+ 2 + 1) = 0

⇒ ( x+ 1 ) ( x+ 3 ) = 0

⇒ x = -1  or x = -3

Therefore, the value of x = -1 or x = -3 for the condition f(f(x)) = f(x).

The values of x that satisfy the equation p(−x ≤ t22 ≤ x) = 0.98 are all values between -2.518 and 2.518, inclusive.

The expression p(- x ≤ t22 ≤ x) represents the probability of a t-distribution with 22 degrees of freedom lying between - x and x.

We want to find the values of x such that this probability is 0.98.

We can use a table of t-distribution probabilities or a calculator to find the value of t for which the probability of a t-distribution with 22 degrees of freedom lying between −t and t is 0.98.

This value is , 2.518.

Therefore, we need to solve the inequalities:

-2.518 ≤ -x ≤ 2.518

Solving for x, we get:

-2.518 ≤ -x x ≤ 2.518

Step-by-step explanation:

p=3, r=4

12.1*3= 36.3

11.5*4= 46

36.3+46= 82.3

Answer:

82.3

Step-by-step explanation:

Hi there!

We are given the expression 12.1p+11.5r, and we want to evaluate it if p=3 and r=4

We need to simply substitute the given values into 12.1p and 11.5r respectively, then add the numbers together

If p is equal to 3, then that means that 12.1p is equal to 12.1*3, which would be 36.3

If r is equal to 4, then that means 11.5r is equal to 11.5*4, which would be 46

Now add 36.3 and 46 together

36.3+46=82.3
