A recursive definition for the set S can be given as follows:

What is recursion?

Recursion is a programming technique where a function calls itself to solve a problem.

Base case: (1, n) is in S for all positive integers n, since 1 is a factor of all positive integers.

Recursive case: If (a, b) is in S, then (a', b) is in S for all positive integers a' that are factors of a, and (a, b') is in S for all positive integers b' that are multiples of b.

In other words, the set S contains all pairs (a,b) where a is a positive integer that divides b, and b can be obtained by multiplying any such a with another positive integer. The base case includes all pairs where a=1 and b is any positive integer.

The recursive case states that if (a,b) is in S, then all pairs where a' is a factor of a and b is a positive integer such that b=a'b are also in S, as well as all pairs where b' is a multiple of b and a is a positive integer that divides b'.

A specific X-value for the solution ,-4 is not equal to -3/2.

The x-value of the solution to the system of equations, we need to solve the given equation and the line represented by the data in the table. Let's begin by examining the first equation, 2x + 4y = 0.

We can rewrite this equation in terms of y:

4y = -2x

y = (-2/4)x

y = (-1/2)x

Now, let's use the data from the table to create a system of equations:

For the first data point (-1, 8):

y = (-1/2)x

8 = (-1/2)(-1)

8 = 1/2

Since 8 is not equal to 1/2, the first data point does not satisfy the equation.

For the second data point (3, -4):

y = (-1/2)x

-4 = (-1/2)(3)

-4 = -3/2

Again, -4 is not equal to -3/2, so the second data point does not satisfy the equation.

We can continue this process for the remaining data points, but from the information given, it seems that none of the data points satisfy the equation. Therefore, there is no solution to the system of equations.

Step-by-step explanation:

Divide the top and bottom by 2

Answer :

Reduce the fraction

using simultaneous equation:

2x + 3y = 190

3x + y = 180  * 3

Then:

2x + 3y = 190

9x + 3y = 540

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

-7x = -350

x = 50

Insert this in equation 1 to find value of y:

2x + 3y = 190

2(50) + 3y = 190

3y = 190 - 100

3y = 90

y = 30

expanding the following:

\(\rightarrow \sf (5)^3+6(5)^2+12(5)+8\)

\(\rightarrow \sf 125+150+60+8\)

\(\rightarrow \sf 343\)

Answer:

Step-by-step explanation for (a):

First use system of equations. Isolate a variable and substitute.

2x + 3y = 190

3x + y = 180

Isolate

subtract 3x from both sides of the second equation

y = 180 - 3x

since 180 - 3x = y, you can substitute this into the first equation for y

Substitute

2x + 3y = 190

2x + 3(180 - 3x) = 190

Distribute the 3

2x + (540 - 9x) = 190

Solve for x

subtract 540 from both sides

2x - 9x = -350

simplify

-7x = -350

divide each side by -7

x = 50

But you still need to solve for y, so substitute the x back into the first equation.(But really you could use either equation)

2(50) + 3y = 190

subtract 100 (2 * 50) from both sides

3y = 90

y = 30

Check your work by resubstituting.

3(50) + 30 = 180.

(b) This one is weird.

(Remember, it is NOT (x^3 + 8), you don't "distribute" the exponent)

It then simplifies to x^3 + 6x^2 + 12x + 8, and x = 5 is NOT an answer here. Maybe there is something more that you might not have screenshotted?

*edit its not asking to prove x is a solution(which i thought lolllll) its asking to plug x = 5 into the equation*

The value of the variables in the right triangle are as follows;

A right triangle is a triangle that has one of its angles as 90 degrees.

The side of a right triangle can be found by using trigonometric ratios.

Therefore, let's find the variable length of the right triangle as follows;

sin 30 = opposite / hypotenuse

sin 30 = v / 3√2

1 / 2 = v / 3√2

cross multiply

3√2 = 2v

divide both sides by 2

v = 3√2 / 2

Let's find the variable w.

cos 30 = adjacent  / hypotenuse

cos 30 = w  / 3√2

√3 / 2 = w  / 3√2

cross multiply

√3 × 3√2 = 2w

3√6 = 2w

divide both sides by 2

w = 3√6 / 2

Answer:

Total surface area = 468 in.²

Step-by-step explanation:

Total surface area of triangular prism = 2BA + PH

Base area (BA) = ½*bh

b = 9 in.

h = 12 in.

2BA = 2(½*9*12) = 108 in.²

Perimeter of base (P) = 9 + 12 + 15 = 36 in.

Height of prism (H) = 10 in.

Plug in the values

Total Surface area of triangular prism = 108 + 36*10 = 468 in.²

The function s(x) = -2, 3, 8, 13 could be the inverse of function f(x).

The correct option is C.

To determine the inverse of the given function f(x), we need to find a function that, when applied to the output of f(x), returns the input value.

Let's analyze the given function f(x):

x -1 0 1 2

f(x) -2 3 8 13

To find the inverse function, we need to swap the input and output values.

So, the input values of f(x) become the output values of the inverse function, and vice versa.

Let's examine the options:

A. x -2 3 8 13

q(x) -1 0 1 2

B. x -2 -3 -8 -13

r(x) 1 0 -1 -2

C. x 1 0 -1 -2

s(x) -2 3 8 13

D. x -1 0 1 2

p(x) 2 -3 -8 -13

By comparing the input and output values of the inverse functions with the original function f(x), we can see that option C (x and s(x)) matches the inverse function.

In Algebra, an inequality is a mathematical statement that uses the inequality symbol to illustrate the relationship between two expressions. An inequality symbol has non-equal expressions on both sides. It indicates that the phrase on the left should be bigger or smaller than the expression on the right, or vice versa. Literal inequalities are relationships between two algebraic expressions that are expressed using the inequality symbols.

The give inequality is:

Regroup the variables such that n is on the same side of the equation:

6n - n < 4 + 30

5n < 34

Answer: 43) y = -x² - 2x + 3

              44) y = (1/2)x² + 2x + 3

Step-by-step explanation:

43) Since the x-intercepts and another point are given, use the Intercept form:

          y = a(x - p)(x - q) where

Given: p = -3,    q = 1     (x, y) = (-1, 4)

y = a(x - p)(x - q)

y = a(x + 3)(x - 1)

4 = a(-1 + 3)(-1 - 1)

4 = a(2)(-2)

4 = -4a

-1 = a

Equation: y = -1(x + 3)(x - 1)

Expand:   y = -(x² - x + 3x - 3)

                   = -(x² + 2x - 3)

                   = -x² - 2x + 3

***********************************************************************************

Since the vertex and another point are given, use the Vertex form:

              y = a(x - h)² + k   where

Given: (h, k) = (-2, 1)  and   (x, y) = (0, 3)

y = a(x - h)² + k

y = a(x + 2)² + 1

3 = a(0 + 2)² + 1

3 = 4a + 1

2 = 4a

1/2 = a

Equation: y = (1/2)(x + 2)² + 1

Expand:   y = (1/2)(x² + 4x + 4) + 1

                  = (1/2)x² + 2x + 2 + 1

Note that in the prompt above, the value of x is given as: 16°

To answer the issue, we will first name all of the points supplied to us on the isosceles triangle, then identify O, and last discover the value of x. See the attached image.

As a result, an isosceles triangle has two equal sides and two equal angles. The term is derived from the Greek words iso (same) and skelos (skull) (leg). An equilateral triangle has all of its sides equal, whereas a scalene triangle has none of its sides equal.

In ΔAOB

OA =  OB = R, the radius of the circle O,

therefore, the ΔAOB is an isosceles triangle, with OA, OB as the congruent sides and AB as the base of the triangle.

Thus, ∠OAB = ∠OBA = 53°

Sum of all the angles of a triangle = 180°

∠O + ∠AOB + ∠OBA = 180°

We know ∠AOB = ∠OBA, therefore,

∠O + 2(∠AOB) = 180°

∠O + 2(53°) = 180°
∠O = 180 - 106

∠O = 74°

In ΔOBC,

BC is the tangent to the circle O, therefore,

∠OBC = 90°

Sum of all the angles of a triangle = 180°

∠O + ∠OBC + ∠OCB = 180°

74° + 90° + ∠OCB = 180°

∠OCB = 180° - 74° - 90°

∠OCB = 16°

Hence, the value of x is 16°.

The population of organisms is described by the following exponential equation:

P(t) = 18,000*(0.9966)^t

The general exponential equation is:

P(t) = A*(b)^t

Where A is the initial value, b depends on the percentage that changes, and t is the variable.

In this case, the population decreases by 3.4%, then we have:

B = 1 - 3.4%/100% = 0.9966

And the initial value is 18,000 organisms, replacing that in the general equation we get:
