Suppose that f(x) = h^−1(x) and that both j and h are defined for all values of x. Let h(11) = 2 and f(12) = −7. We need to evaluate the following. h(2) + j(−7)For finding the value of h(2), we can use f(x) = h^−1(x) where x = h(2)f(h(2)) = 2h(2) = f^−1(2)We need to find h(2). Therefore, we need to find f^−1(2). We know f(12) = −7f(h(2)) = 2⟹ h(2) = −7Substitute h(2) = −7 in h(11) = 2h(11) = h(2 + 9) = h(2) + 9 = 2 + 9 = 11Therefore, h(2) = −7 and h(11) = 2.h(2) + j(−7) = −7 + j(−7) = −7(1 + j)Therefore, h(2) + j(−7) = −7(1 + j).

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

Mr. Moore has a rectangular prism shaped planter box to grow herbs inside his house. The dimensions of the planter box are 4. 5 feet long, 2 feet wide, and 1. 5 feet tall. How any cubic feet of soil does Mr. Moore need in order to fill the planter box

Answers

Mr. Moore needs 13.5 cubic feet of soil to fill the planter box.

To calculate the volume of the rectangular prism planter box, we need to multiply the length, width, and height of the box.

Volume = length x width x height

V = 4.5 ft x 2 ft x 1.5 ft

V = 13.5 cubic feet

Therefore, Mr. Moore needs 13.5 cubic feet of soil to fill the planter box.

It is important to note that the volume of the box represents the amount of space inside the box and does not take into account any obstructions or irregularities that may be present inside the box.

Thus, the actual amount of soil required may be slightly different from the calculated value. Additionally, it is always a good idea to add some extra soil to account for settling and to ensure that the planter box is completely filled.

Answers

As per the given triangle, the length of AB rounded to 3 significant figures is 10.7 units.

We are given a triangle ABC with a right angle at A, i.e., CAB = 90°. Let AC be the side opposite to the right angle, and let AB be the hypotenuse. We are also given that ABC = 57° and AC = 9.2.

Using the trigonometric function, we can relate the angles and sides of a right-angled triangle. In particular, we can use the sine function to relate the angle opposite to a side and the hypotenuse. Thus, we have:

sin(ABC) = AC/AB

Substituting the given values, we get:

sin(57°) = 9.2/AB

Now, we can solve for AB by multiplying both sides by AB and dividing by sin(57°):

AB = 9.2/sin(57°)

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.

How is a function solved?

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.

As a result, we must identify the range of x values for which either f(x) or f(-x) = 1/4.

Answers

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

What is Premium rate?

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.

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

(√3, 1) and (-√3, 1)

What are common chords of a circle?

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

If a pair of opposite angles of a parallelogram are (3x+10)⁰and (4x_10)⁰,find the internal angles​

Answers

Answer: In a parallelogram, opposite angles are equal, so we can set up the following equation:

3x + 10 = 180 - (4x + 10)

Simplifying and solving for x, we get:

3x + 10 = 170 - 4x

7x = 160

x = 20

Now we can substitute x = 20 into the expressions for the angles to find their values:

3x + 10 = 70 degrees

4x + 10 = 90 degrees

Since opposite angles in a parallelogram are equal, the other two angles must also be equal to these values. Therefore, the internal angles of the parallelogram are:

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

What are all the possible zeros of the function

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:

x = (3 ± i√103) / 2

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 ...

  AV/AP = AZ/AW

  (4+x)/x = (3+6)/6

  4/x +1 = 3/6 +1 . . . . . do the division

  4/x = 3/6 . . . . . . . . subtract 1

  x/4 = 6/3 . . . . . . invert both sides . . . compare to above

the two line segments below each have the same length l. if you were to calculate the integral the contour integer of the dot product of vector b with respect to vector s for each path, which one would yield b times l?

Answers

In response to the given question, we can state that To compute the function contour integral and establish the value of b times l for each path, the precise path of the line segments must be specified.

what is function?

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 letter f is widely used this to denote functions (x). The symbol for admission is an x. The four primary types of usable functions are on operations, one-to-one capabilities, so multiple functionality, in capabilities, and then on functions.

It is impossible to predict which path would provide a contour integral of b times l for the dot product of vector b with respect to vector s without knowing the precise trajectories of the line segments.

The contour integral of a vector field F's dot product with respect to a curve C is given by:

∫C F · ds

To compute the contour integral and establish the value of b times l for each path, the precise path of the line segments must be specified.

Which is CLOSEST to the curve of best fit for the data shown?

(a). y = -10x^2 - 0.5x + 8
(b). y = -2x^2 + 0.2x +23
(c). y = -8x^2 - 0.5x + 9
(d). y = -5x^2 - 18x + 66

Answers

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

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

How to interpret the line of best fit?

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

y = 43

As a result, 140140140 tamales would be left as Claudio began with 300300300 and distributed samples to 160160160 passersby.

what is expression ?

An expression in mathematics is made up of different numbers, variables, and mathematical operations like addition, subtraction, multiplication, division, and exponentiation. Expressions can be simple or complicated and can express a wide range of mathematical connections and concepts. Expressions can be evaluated to get a numerical result or to be simplified using mathematical principles and rules. For instance, the equation "2 + 3" can be evaluated to get the value "5", whereas the expression "2x + 3y - 4z" can be made easier by fusing comparable terms to produce a more straightforward expression, such as "2x - z + 3y."

given

The quantity of tamales left if Claudio began with 300300300 and distributed samples to 160160160 passersby would be:
