This is an example of

C. simultaneous causality.

Step-by-step explanation:

Simultaneous causality eliminates the conclusion that is often taken for granted to the effect that one variable is a response variable while the other is an explanatory variable because the two variables, the price and the number of shares, influence each other at the same time.  When more shares are traded than demanded in the stock market in any day, the price tends to go down, and vice versa.

Answer:

1 - 3√(5/35) = 1 - 3√(1/7) = 1 - 3*(1/sqrt(7)) ≈ 0.0755
0.0755 * 100 = 7.55%

Step-by-step explanation:

To find the percentage of 1 - 3√(5/35), we need to first evaluate the expression.

1 - 3√(5/35) = 1 - 3√(1/7) = 1 - 3*(1/sqrt(7)) ≈ 0.0755

To convert this decimal to a percentage, we simply multiply by 100:

0.0755 * 100 = 7.55%

Kamryn would save $159.99 in interest by raising her credit score from 665 to 680 when borrowing $13,250.00 with a simple interest rate loan.

To determine the amount of interest Kamryn will save by raising her credit score from 665 to 680, we need to compare the interest rates associated with each credit score range.

According to the given information, a credit score of 665 falls within the range of 580-669, where the corresponding simple interest rate is 10.358%.

Let's calculate the interest Kamryn would pay on a loan of $13,250.00 at an interest rate of 10.358%.

Interest = Principal * Rate

= $13,250.00 * 0.10358

≈ $1,370.56

Therefore, if Kamryn were to borrow $13,250.00 with a credit score of 665, she would pay approximately $1,370.56 in interest.

Now, let's consider the scenario where Kamryn raises her credit score to 680. A credit score of 680 falls within the range of 670-739, where the corresponding simple interest rate is 9.132%.

Calculating the interest with a credit score of 680:

Interest = Principal * Rate

= $13,250.00 * 0.09132

≈ $1,210.57

Thus, if Kamryn were able to raise her credit score from 665 to 680, she would save approximately $1,370.56 - $1,210.57 = $159.99 in interest.

Therefore, Kamryn would save approximately $159.99 in interest by raising her credit score from 665 to 680 when borrowing $13,250.00 with a simple interest rate loan.

A. The graph of the absolute value function is V-shaped, with the features given as follows:

B. The transformation is that the function was shifted right two units, hence the features are given as follows:

The absolute value function, with vertex (h,k), is defined as follows:

y = |x - h| + k.

The features of the function are given as follows:

For the first item, the function is |x + 3|, hence we just have to identify the features.

For the second function, the definition if h(x) = |x - 2|, with vertex at (2,0), meaning that the function was shifted two units right from the parent absolute value function y = |x|. The shift just changes the turning point of the graph, not altering domain and range.

Answer:

a) The area of the rectangle is given by the product of its length and width. Thus:

Area = (4x - 3) * 2

Area = 8x - 6

b) The perimeter of a rectangle is the sum of the lengths of all four sides. The perimeter of this rectangle can be expressed as:

Perimeter = 2 * (length) + 2 * (width)

Perimeter = 2 * (4x - 3) + 2 * 2

Perimeter = 8x - 6 + 4

Perimeter = 8x

cos(2θ) + sin²(θ) = 0

Half-angle identity:

cos(2θ) = -1

Solve for θ :

The equation ((22)3) = 25 is false.

Two or more expressions with an Equal sign is called as Equation.

The given equation is  ((22)3) = 25.

We have to check whether the left hand side is equal to right hand side.

If the LHS and RHS are equal then the equation is true.

If not then it is false.

The probability of roll outcome:

1st 2 = 1/6

2nd prime = 1/2, and

3rd more than 4 = 1/3.

Probability is the fraction of the required outcome event divided by the number of possible outcomes of events.

In a fair die, considering the outcomes from the question:

probability of the 1st roll to be 2 = 1/6

probability of 2nd roll to be prime = 3/6

probability of 2nd roll to be prime = 1/2

probability of 3rd roll to be more than 4 = 2/6

probability of 3rd roll to be more than 4 = 1/3

A = lw

To solve the given equation for w, we will divide both sides of the equation by l

That is,

A/l = lw/l

So that

A/l = w

and

w = A/l

Answer:48

Step-by-step explanation:

The polar equations converted into Cartesian equations are listed below:

Case 28: x² + (y - 3 / 2)² = (3 / 2)² (Circle)

Case 29: (x - 2)² + y² = 2² (Circle)

Case 30: x + 7 · y - 4 = 0 (Line)

Case 31: x + 3 · y = 6 (Line)

Case 32: x - 2 = 0 (Line)

Case 33: y - 3 = 0 (Line)

Case 34: (x - 1 / 2)² + y² = (3 / 2)² (Circle)

Case 35: x · y = 4 (Hyperbola)

Case 36: x² + y² = 4² (Circle)

Case 37: x² + y² = 2² (Circle)

Case 38: 4 · x - 3 · y - 1 = 0 (Line)

Case 39: x - 5 · y - 3 = 0 (Line)

In this question we find 12 cases of polar equations that must be converted into Cartesian equations. This can be done by following operations:

r = f(θ) → y = f(x)

x = r · cos θ, y = r · sin θ

r = √(x² + y²)

Now we proceed to find the Cartesian equations:

Case 28

r = 3 · sin θ

r = 3 · (y / r)

r² = 3 · y

x² + y² = 3 · y

x² = 3 · y - y²

x² + y² - 3 · y = 0

x² + (y² - 3 · y + 9 / 4) = 9 / 4

x² + (y - 3 / 2)² = (3 / 2)²

Case 29

r = 4 · cos θ

r = 4 · (x / r)

r² = 4 · x

(x² - 4 · x) + y² = 0

(x² - 4 · x + 4) + y² = 4

(x - 2)² + y² = 2²

Case 30

r = 4 / (sin θ + 7 · cos θ)

r · sin θ + 7 · r · cos θ = 4

x + 7 · y - 4 = 0

Case 31

r = 6 / (cos θ + 3 · sin θ)

r · cos θ + 3 · r · sin θ = 6

x + 3 · y = 6

Case 32

r = 2 · sec θ

r = 2 / cos θ

r = 2 · r / x

x = 2

x - 2 = 0

Case 33

r = 3 · csc θ

r = 3 / sin θ

r = 3 · r / y

y = 3

y - 3 = 0

Case 34

r = √(r · cos θ + 2)

r² = r · cos θ + 2

x² + y² = x + 2

x² + y² - x - 2 = 0

(x² - x + 1 / 4) + y² = 9 / 4

(x - 1 / 2)² + y² = (3 / 2)²

Case 35

r² = 4 · sec θ · csc θ

r² = 4 · r² / (x · y)

x · y = 4

Case 36

r = 4

√(x² + y²) = 4

x² + y² = 4²

Case 37

r² = 4

x² + y² = 2²

Case 38

r = 1 / (4 · cos θ - 3 · sin θ)

4 · r · cos θ - 3 · r · sin θ = 1

4 · x - 3 · y - 1 = 0

Case 39

r = 3 / (cos θ - 5 · sin θ)

r · cos θ - 5 · r · sin θ = 3

x - 5 · y - 3 = 0

Answer:

The original number is -22

Step-by-step explanation:

We'll label our mystery number x.

2x + 36 = 4x/11
Multiply both sides by 11
4x = 22x + 396
Isolate x to one side (for this I subtract 4x from both sides, but you can also subtract 22x if you'd like)
0 = 18x + 396
Isolate x pt 2
18x = -396
Divide both sides by 18 to find your answer!
x = -22

Plug in to confirm

-44 + 36 = -88/11S
