An investor has an account with stock from two different companies. Last year, her stock in Company A was worth $4500 and her stock in Company B was worth $3900. The stock in Company A has increased 5% since last year and the stock in Company B has increased 11%. What was the total percentage increase in the investor's stock account? Round your answer to the nearest tenth (if necessary).

The CLOSEST to the curve of best fit for the data shown is:

(c). y = -8x^2 - 0.5x + 9

The line of best fit is defined as a straight line that is drawn to pass through a set of plotted data points that produces the best and most approximate relationship between such given data points.

From the given graph, we see that:

at x = 1, y = 0

Thus:

a) -10x² - 0.5x + 8

Plugging x = 1:

-10(1)² - 0.5(1) + 8

= -10 - 0.5 + 8 = -2.5

b) y = -2x² + 0.2x + 23

At x = 1:

y = -2(1)² + 0.2(1) + 23

y = 21.2

c) y = -8x² - 0.5x + 9

At x = 1:

y = -8(1)² - 0.5(1) + 9

y = -8 - 0.5 + 9

y = 0.5

d)  y = -5x² - 18x + 66

At x = 1:

y = -5(1)² - 18(1) + 66

The answer of the given question based on the interest rate the answer is  the premium paid for each subsequent year would be ¢840

A premium rate is price per unit of insurance coverage for specific risk that an insurer charges its policyholders. It is typically expressed as  percentage of  total insured value of  policy.

To calculate the premium paid for subsequent years, we need to know what the premium rate is for those years. The premium rate may change from year to year depending on various factors such as the age of the car, the driver's record, etc.

Assuming the premium rate remains constant at 8% of the insured value for all subsequent years, we can calculate the premium paid for each year as follows:

First year: 8% of ¢10,500 = ¢840

Second year: 8% of ¢10,500 = ¢840

Third year: 8% of ¢10,500 = ¢840

And so on...

So the premium paid for each subsequent year would be ¢840 if the premium rate remains constant at 8% of the insured value.

Mathematicians examine numbers and complex variations, equations and associated structures, forms and their locations, and prospective positions for these things. The term "functioning" signifies the connection between a collection of inputs, each of which has a corresponding output. A function is a connection of inputs and results in which each input leads to a single, identifiable outcome. Each function is assigned a domain, a codomain, or a scope.

The scale factor of the dilation of the vertices of the cone when dilated is 4.5

The area of a circle is proportional to the square of its radius. Since the base of the cone is a circle

The ratio of the areas of the base of the dilated cone to the original cone is equal to the square of the scale factor.

Let the scale factor be k. Then, we have:

(area of dilated cone's base) / (area of original cone's base) = k²

(729π) / (36π) = k²

k² = 20.25

ii. The points of intesection of the common chords of the curve x² + y² = 4 and x² - 4y + 1 = 0 are

The common chords of circles are the chords that pass through the points of intersection of the curves.

i. Given the curve x² + y² = 4 and y² = 3x. We desire to find their points of intesection of the common chords. We proceeds as follows.

Since  x² + y² = 4 and y² = 3x. Substituting the second equation into the first, we have

x² + y² = 4 and y² = 3x.

x² + 3x = 4

Re-arranging, we have

x² + 3x - 4 = 0

Factorizing the quadratic equation, we have

x² - x + 4x - 4 = 0

x(x - 1) + 4(x - 1) = 0

(x + 4)(x - 1) = 0

⇒ x + 4 = 0 and x - 1 = 0

⇒ x = - 4 and x = 1

Now, y² = 3x.

⇒ y = ±√3x

So.substituting x = -4 into the equation, we have

y = ±√3x

y = ±√(3 × -4)

= ±√(-12)

Since the square root is negative, this answer is invalid.

Substituting x = 1 into y, we have

y = ±√3x

y = ±√3(1)

y = ±√3

So, the points of intersection are (1, √3) and (1,-√3)

ii. Given the curve x² + y² = 4 and x² - 4y + 1 = 0. We desire to find their points of intesection of the common chords. We proceeds as follows.

Since  x² + y² = 4 and x² - 4y + 1 = 0. From the second equation, we have

x² = 4y - 1

Substituting this equation into the first, we have

x² + y² = 4 and x² = 4y - 1

y² + 4y - 1 = 4

Re-arranging, we have

y² + 4y - 1 - 4 = 0

y² + 4y - 5 = 0

Factorizing the quadratic equation, we have

y² - y + 5x - 5 = 0

y(y - 1) + 5(y - 1) = 0

(y + 5)(y - 1) = 0

⇒ y + 5 = 0 and y - 1 = 0

⇒ y = - 5 and y = 1

Now, x² = 4y - 1

⇒ x = ±√(4y - 1)

So, substituting y = -5 into the equation, we have

x = ±√(4y - 1)

x = ±√[(4 × -5) - 1)]

= ±√(- 20 - 1)

= ±√-21

Since the square root is negative, this answer is invalid.

Substituting y = 1 into x, we have

x = ±√(4y - 1)

x = ±√(4(1) - 1)

x = ±√(4 - 1)

x = ±√3

So, the points of intersection are (√3, 1) and (-√3, 1)

In mathematics, numerals are expressed by the ratio of quotient to ratio. Every one of these fractions of integers are simple fractions. The fraction contains a fraction, but the fraction's remainder is a challenging fraction. because the values, 4.91, and numerators of real fractions can vary.

Here,

We can begin by isolating the variable with one side of the solution in order to solve for y. The reciprocal of fraction on the left side of the equation can be used to add both sides of the equation to achieve this:

=> 2/5 = (y - 4)/3

=> 3 * 2/5 = y - 4 [add 3 to both ends]

=> 6/5 = y - 4 [simplify]

=> y = 6/5 + 4 [Adjust both ends by 4]

=> y = 6/5 + 20/5 Using the denominator 5 as the corresponding fraction, write 4.

=> y = 26/5

a. The possible zeros of the polynomial function are ±1, ±2, ±5, ±10, ±25, ±50

b. x = -1 is a zero of f(x)

c. The remaining zeros of the polynomial function is -1, (3 + i√103) / 2, (3 - i√103) / 2

To find all possible zeros of the polynomial function f(x), we can use the Rational Root Theorem, which states that if a polynomial function with integer coefficients has a rational zero of the form p/q, where p and q are integers and q ≠ 0, then p must be a factor of the constant term and q must be a factor of the leading coefficient.

The constant term of f(x) is 50, which has the factors ±1, ±2, ±5, ±10, ±25, ±50. The leading coefficient of f(x) is 1, which has the factors ±1. So the possible rational zeros of f(x) are:

±1, ±2, ±5, ±10, ±25, ±50

b. We can use synthetic division to test each of the possible rational zeros and find an actual zero. Let's start by testing x = 1:

  | 1  -2  -25  50

1  |    1   -1  -26  24

  |______________

  1  -1  -26  24

The remainder is 24, which means that x = 1 is not a zero of f(x).

Let's try x = -1:

  | 1  -2  -25  50

-1 | 1 -3 28 -78

|______________

1 -3 28 -78

The remainder is -78, which means that x = -1 is a zero of f(x).

c. We can use the quotient from part (b), which is x^2 - 3x + 28, to find the remaining zeros of the polynomial function f(x). To do this, we can use the quadratic formula:

x = (-b ± √(b^2 - 4ac)) / 2a

where a = 1, b = -3, and c = 28. Plugging in these values, we get:

x = (3 ± √(-103)) / 2

Since the discriminant is negative, there are no real solutions. However, there are two complex solutions:

When a segment is drawn in a triangle parallel to the base, it divides the sides proportionally. Every segment on the left has the same ratio to the corresponding segment on the right:

  x/6 = 4/3

This equation is solved in the usual way. Multiply by the inverse of the coefficient of x:

  6(x/6) = 6(4/3)

  x = 8

Every proportion can be written several ways. Another way to write this one is ...

  x = 4(2) = 8 . . . . . multiply by 4

If you need to, you can prove the triangles are similar by considering corresponding angles. ∠A≅∠A, ∠APW≅∠AVZ, so the triangles are similar by the AA postulate. (Corresponding angles where a transversal crosses parallel lines are congruent.)

Perhaps not so obvious is the relationship between segments of the long side and segments of the short side. The similarity relation tells us ...

In conclusion, we need to identify the set of values of x for which either f(x)=-1/4 or f(-x)=-1/4 in order to solve to the equation f(|x|)=-1/4.

The expression f(|x|)=-1/4 indicates that the absolute value of x's function f is equal to 1/4. Any x values that satisfy this equation are what we are trying to find. We can rewrite the equation as f(x)=-1/4 when x is positive and f(-x)=-1/4 when x is negative because the absolute value of x is always positive.

We must search for values of x such that f(x)=-1/4 or f(-x)=-1/4 in order to identify the answers. Without knowing more about the function, f may be anything, hence we cannot know the precise solutions.

Therefore, we can state that x or -x is a solution to the equation if there is a value of x such that f(x)=-1/4 or f(-x)=-1/4.
