Step-by-step explanation:

The functions that are symmetric about the y-axis are;

1) The function in the first option; f(θ) = cos(θ)

2) The function in the third option; f(x) = x²

Definition;

A function is symmetric about the y-axis is also known to be an even function such that the same value of the function is arrived at when x is replaced with -x

Analysis of the graphs;

First Function Graph; The graph represents the graph of cos (θ)

∴ The function is f(θ) = cos(θ)

The value of the function when x = π, f(π) = -1

Similarly, the value of the when x = -π, f(-π) = -1

f(π) = f(-π)

∴ f(x) = f(-x)

Therefore; the first function is an even function

Second Function Graph; The function of the graph is x = y²

∴ y = √(x)

The value of the function when x = 4, y = f(4) = 2

However, the when x = -4, f(-4) does not exist

f(4) ≠ f(-4)

∴ f(x) ≠ f(-x)

Therefore; the second function is not an even function (the function, x =

y², is however symmetric about the x-axis)

Third Function Graph; The function the graph represents is y = x²

The value of the function when x = 2, f(2) = 4

Similarly, the value of the when x = -2, f(-2) = 4

f(2) = f(-2)

∴ f(x) = f(-x)

Therefore; the third function is an even function

From the above, the functions which are symmetric about the y-axis, (even functions) are;

From the rectangle, the value of x is 4.9 or -2.4

A rectangle is a four sided polygon whose opposite sides are equal and parallel, The area can be defined as the amount of space covered by a flat surface of a particular shape. It is measured in terms of the "number of" square units (square centimeters, square inches, square feet, etc.)

The parameters given for the solution are

Area = 24m

Length = x+2

width = 2x-9

Area = l*w

This implies that (x+2)(2x-9)=24

Collecting like terms we have

2x2-5x-24=0

Solving the equation we have

(5±√25+192)/4

⇒(5±√217)/4

⇒(5+14.7)/4 or( 5-14.7)/4

x=4.9 or x = 2.4

Therefore the value of x in the figure is 4.9 and -2.4 respectively

The coordinates of the vertices after the reflection over the line y = -x is K'(-5, -4), L'(-7, -7), M'(-9, -4) and N'(-7, 1).

Reflection is a type of geometric transformation where the figure is flipped. In other words, a figure when undergoes reflection becomes it's mirror image.

Given a quadrilateral KLMN.

The coordinates of the vertices are,

K(4, 5), L(7, 7), M(4, 9) and N(-1, 7)

The point (x, y) after the reflection over the line y = -x is the point (-y, -x).

The given rule t–3, 5(x, y) states that the triangle is translated 3 units to the left, and 5 units up on the coordinate plane. This can be rewritten as (x, y) → (x – 3, y + 5). This means that for each point (x, y), the new point after the translation will be (x – 3, y + 5). In other words, the x-coordinate of the new point will be three units less than the original x-coordinate, and the y-coordinate of the new point will be five units more than the original y-coordinate. This translation of the triangle can also be visualized as moving the triangle three units to the left and five units up on the coordinate plane.

Answer:

0.13 to 0.30 mp

Step-by-step explanation:

one angstrom, symbolized as å, is 10-10 m, so

1 cm^3 = 10^24 angstrom^3

The angstrom, sometimes known as a ångström, is a metric length unit equal to 10^(-10)m, or one ten billionth of a metre, one hundred millionth of a centimeter, 0.1 nanometer, or one hundred picometres. The Swedish alphabet letter serves as its symbol. The Swedish physicist Anders Jonas Angström is commemorated by the unit's name.

The length of an object is measured in centimeters, which are metric units of measurement. The abbreviation is cm.

100 centimeters make up a meter.

One centimeter is equal to ten millimeters.

so one angstrom is 10^-10 m, or 10^-8 cm, so there are 10^8 angstroms in 1 cm.

1 cm^3 = 1 cm 1 cm * 1 cm

For a function, f(x) = 1 + 3x , the computed value of lim h→0 [f(5 + h) − f(5)]/h is equals to the three.

In Mathematics, the limit of a function is a value of the function as the input of the function tries approaches some number. Function limits are used to define continuity, integrals, and derivatives. Mathematically, let f(x) be a function and L be limit of function, f(x) at x a exist if and only if lim f(x) = lim f(x) = L

x→a⁻ x→a⁺

We have, f(x) = 1+3x and will compute lim h→0 [f(5 + h) − f(5)]/h . Firstly, determine the value of function at x = 5 , x = 5+h.

So, f(5) = 1+ 3×5 = 16 and f(5+ h) = 1+3(5+h)

= 16+ 3h

Now, lim [ f(5 + h) − f(5)]/ h

h→0

= lim [(16 + 3h) − (16) ]/ h

h→0

= lim [ 16 + 3h - 16 ]/ h

h→0

= lim [ 3h/ h ] = lim [ 3h¹h⁻¹ ]

h→0 h→0

= lim [ 3h¹⁻¹ ] = lim [ 3h⁰ ]

The product requested is equal to -108.8. The result found is a rational number.

The numbers can be classified as rational or irrational.  A number is classified as a rational number when this number is represented by a ratio between two integers numbers ([tex]\frac{b}{c}[/tex]), where c ≠0.  Besides, this ratio can be simplified in decimal form.

On the other hand, an irrational number represents a number that cannot be written in the form of a fraction, only in decimal form. In this case, the decimal never repeats.

The rules for the multiplication of numbers are:

The result presents a positive sign (+) because the signs are the same.

The result presents a negative sign (-) because the signs are different.

The question asks the product between [tex]\sqrt{1024}[/tex] and -3.4.

A. The result of the iterated integral by converting to polar coordinates is 0.

To evaluate this iterated integral, we will convert it to polar coordinates. First, we need to make the substitution x = rcos(θ) and y = rsin(θ). Then, we will need to find the limits of integration for r and θ. The region of integration is the area between the circles with radii a and 2 and between the x-axis and y-axis.

In polar coordinates, the integral becomes ∫∫r dr dθ from r = a to r = 2, and θ = 0 to θ = π/2.

We can now solve the integral by multiplying the integral of r by the integral of θ.

∫2^2 r dr dθ = ∫π/2^0 (-1/2)r^3 dθ = -1/2 * [(r^2)/2] from r = 2 to r = a = -1/2*(2^2 - a^2) = -1/2*(4-a^2) = -2+a^2/2

So the result of the integral is -2+a^2/2 = -2+4/2 = -2+2 = 0

Note that this is not a common way to solve iterated integrals, but rather a way to check the correctness of the solution. The common way is to find the limits of integration by solving the inequality and graphing the area of integration.
