The domain of f(x) is equal to the range of inverse function g(x).

What are inverse functions?

A function from a set X to a set Y in mathematics assigns each element of X the exact same number of elements from Y. A function's inverse function reverses the action of a function or f. If and only if the function is bijective, the inverse of f is true.

Given two functions f(x) and g(x).

It is also said that g(x) is the inverse of f(x).

One of the properties of inverse functions is that only one-to-one functions are inverse. If g is equal to f's inverse, then f is equal to g's inverse.

Both f and g are one-to-one functions if they are the inverses of one another.

f and g are inverses of each other if (fog)(x) = x, x ∈ the domain of g.

The range of g equals the domain of f, and the domain of f equals the range of g.

Therefore the domain of f(x) is equal to the range of inverse function g(x).

Answer:

C = 235

Step-by-step explanation:

given the graph passes through (10, 1 ) then the coordinates of the point make the equation true.

substitute x = 10, y = 1 into the equation and solve for C

10² + 1² + 12(10) + 14(1) - C = 0

100 + 1 + 120 + 14 - C = 0

235 - C = 0 ( subtract 235 from both sides )

- C = - 235 ( multiply both sides by - 1 )

C = 235

Let the points for an arrow into target A = x

Let the points for an arrow into target B = y

Vertex A: (90°, 3) and Vertex B: (90°, -1) of the sine function.

The vertex A of the curve y = sin x + 2 is obtained by shifting the vertex of y = sin x upward by 2 units. Since the vertex of y = sin x is (90°, 1), the vertex of y = sin x + 2 will be:

A = (90°, 1 + 2) = (90°, 3)

Therefore, the coordinates of the vertex A of the curve y = sin x + 2 are (90°, 3).

b) The curve y = -sin x is obtained by reflecting the curve y = sin x about the x-axis. Since the vertex of y = sin x is (90°, 1), the vertex of y = -sin x will be:

A = (90°, -1)

Therefore, the coordinates of the vertex A of the curve y = -sin x are

(90°, -1).

The ant can travel 196 inches in 1 minute and 1372 inches in 7 minutes.

To discover the unknown values in a mathematical equation, we cross multiply the numbers in the equation. The method of cross multiplication is frequently employed to identify the missing variable in an equation. We multiply both the numerator and denominator of the provided expression or fractions.

Given that the ant can travel at a constant speed of 980 inches every 5 minutes.

Thus,

5 minutes = 980 inches

1 minute = x inches

Using cross multiplication method or Butterfly method of multiplication we have:

x = 980/5

x = 196 inches.

In 7 minutes the ant can travel:

(7)(196) = 1372 inches.

The zeros of the polynomial function f(x) are:

x = -1, -3/2, -2 + i/2, -2 - i/2

To find the complex zeros of the given polynomial function f(x), we can use the fact that every polynomial with complex coefficients has at least one complex zero.

First, we can use the Rational Zeros Theorem to find any rational zeros. The possible rational zeros are of the form p/q, where p is a factor of the constant term 45 and q is a factor of the leading coefficient 2. Therefore, the possible rational zeros are ±1, ±3/2, ±5, ±9/2, ±15, and ±45/2. We can test each of these values using synthetic division or long division to see if they are actually zeros of the polynomial.

Using long division, we find that x=−1 and x=−3/2 are zeros of the polynomial. Therefore, we can factor out (x+1) and (x+3/2) from the polynomial to get:

f(x) = (x+1)(x+3/2)(2x^3+8x^2+14x+30)

Next, we can use the quadratic formula to find the zeros of the cubic factor 2x^3+8x^2+14x+30. The quadratic formula gives:

x = (-b ± sqrt(b^2 - 4ac)) / 2a

where a = 2, b = 8, and c = 15. Plugging in these values, we get:

x = (-8 ± sqrt(8^2 - 4(2)(15))) / 4

= (-8 ± 2i) / 4

= -2 ± i/2

The number of text messages all of the teenagers in the United States send each month is 17600 million.

In mathematics, an integer is a grouping comprising both positive and negative numbers. Integers are similar to whole numbers in that they do not include the fractional portion. Integers are thus numbers that can be positive, negative, or zero but not fractions. All mathematical operations, including addition, subtraction, multiplication, and division, can be carried out on integers.

Given that,

Number of teenagers = 22 million

Text sent on average = 800

Total messages sent = (22)(800) = 17600 million

The value of CD is 9.92 cm

Find: CD

Triangle ABC is an isosceles triangle with base AB, because AC = BC. In isosceles triangle angles adjacent to the base are congruent. So,

m<A = <mB = 72°

The sum of the measures of all interior angles is 180°, thus

m<C =  180° -72° - 72° = 36°

The area of the triangle ABC is

AABC= 1/2AC.BC.sin<C

If we expand,

AC = 10.43cm

Consider right triangle ACD. In this triangle,

Step-by-step explanation:

The profit the PTO makes from selling raffle tickets can be calculated by subtracting the cost of the tickets from the total revenue generated from ticket sales.

Let's first calculate the total revenue:

Number of tickets sold = 200

Price per ticket = $4

Total revenue = 200 * $4 = $800

Next, let's calculate the cost of the tickets:

Number of tickets sold = 200

Price per ticket = $4

Total cost = 200 * $4 = $800

Finally, we can calculate the profit by subtracting the cost of the tickets from the total revenue:

Profit = Total revenue - Total cost

Profit = $800 - $800 = $0

So, the PTO makes no profit from selling the raffle tickets. This is because the cost of the tickets and the prize are equal, and there are no other expenses. In this scenario, the prize money of $76 is given away to the winner, so the PTO does not get to keep the money for classroom supplies.

Area and Perimeter of Similar Polygons:

Polygons are said to be similar when their corresponding angles are equal and their corresponding sides are in the same proportion. The perimeters and areas of identical polygons have a unique relationship, just as their corresponding sides do.

Perimeters: The scale factor and the perimeters ratios of perimeters are similar. In reality, the scale factor is identical to any ratio between any two similar forms (diagonals, medians, midsegments, altitudes, etc.).

Areas: If the scale factor of the sides of two similar polygons is [tex]\frac{m}{n}[/tex]

, then the ratio of the areas is [tex](\frac{m}{n} )^{2}[/tex].

(Area of Similar Polygons Theorem). Because area is a two-dimensional quantity, you square the ratio.

It is given that ,

the ratio of perimeters of two similar quadrilateral is 2:4.

now,

to find the ratio of area , we can take two quadrilaterals, say square.

Square ABCD of side 2 units and Square PQRS of side 4 units.

now ratio of areas,

[tex]=\frac{area of square ABCD}{area of square PQRS} \\\\=\frac{2*2}{4*4} \\\\=\frac{4}{16}[/tex]

If the given ratio of perimeters can be further solved as 1:2, then we can see that the ratio of areas can also be further solved as 1:4.
