Why can't the denominator of a fraction be negative?

Option (a) represents the correct answer i.e. The value of g(f(9)) is -4.

What is a function?

A relation known as a function connects members of one set in a specific way to those of another set.

Given, f(x)=√x-5 and g(x) = -x²

here, g(f(x)) = g(√x-5 )

                  = - (√x-5)²

 So,  g(f(9)) = - (√9 - 5)²

                   = - (3-5)²

                   = -4

Hence, Option (a) is correct.

Under Trigonometric ratios, the values of sin, cos, and tan are defined by the ratio of sides of a right-angled triangle.

 One of the three fundamental functions in trigonometry, along with cosine and tan functions, is the sine function.

The ratio of the opposite side of a right triangle to its hypotenuse is known as the sine x or sine theta.

To determine a right triangle's unknown angle or sides, utilize the sine function. The sine function for any right triangle with an angle, let's say ABC, will be:

Opposite/hypotenuse = Sin

According to the trigonometric table, the value of Sin 45=[tex]\sqrt[/tex]2/2 which can be simplified as [tex]\sqrt{2} /2[/tex]×[tex]\sqrt{2} /\sqrt{2} =2/\sqrt[]{2}[/tex][tex]=1/\sqrt{2}[/tex]

Answer:

Step-by-step explanation:

The central angle is twice the inscribed angle. So the angle that is behind the one equal to 2x is equal to x. We know that the opposite angles in a circle add up to 180. Therefore, we can solve for x:

[tex]x + x + 42 = 180$^{\circ}$\\\\2x = 180$^{\circ}$ - 42$^{\circ}$\\\\2x = 138$^{\circ}$\\\\x = 69$^{\circ}$[/tex]

Equivalence is a relationship that exists between two statements such that if the two statements are both true or both false, then the affirmation of one and the negation of the other contradicts itself.

Equivalent generally refers to two numbers, terms, or expressions that have the same value. There are many ways to express equivalent quantities. It can be represented by bars or equal signs. "Equivalence" relies on a specific relationship called an equivalence relationship. Any two elements are said to be equivalent if there is an equivalence relation between them. Also, in mathematics, equality is different from equivalent. The same means the same in all respects, and equivalent means similar but not identical. For example, 2 is said to be equal to 2, but it is equivalent to 1 + 1.

(a) The net force equation on q1 is 10.6N towards q2. (b) The acceleration of q1 would be 6.8x10^7m/s^2.

a) The Coulomb's law equation for the force between two charges q1 and q2 is given by:

F = k(q1q2)/r2

Where k is the Coulomb's constant and r is the distance between the two charges.

Using this equation, the force on q1 due to q2 can be calculated as:

F12 = (8.99x109 N m2/C2)(8.00x10-6C)(-5.00x10-6C)/(1.00m)2

F12 = -44.8x10-6 N

Similarly, the force on q1 due to q3 can be calculated as:

F13 = (8.99x109 N m2/C2)(8.00x10-6C)(5.00x10-6C)/(2.00m)2

F13 = 55.2x10-6 N

The net force on q1 can be calculated as the vector sum of F12 and F13:

F1 = F12 + F13

F1 = 10.6N towards q2

b) The acceleration of q1 can be calculated using Newton's second law of motion:

F = ma

a = F/m

Where m is the mass of q1.

Therefore, the acceleration of q1 can be calculated as:

Answer: List 2

Mark the midpoint between 1/6 and 1/2 (see diagram below)

======================================================

Explanation:

There are 3 meats (ham, turkey, bologna) and 2 vegetables (carrots, celery).

This gives 3*2 = 6 different combos of meat plus a vegetable. This is where we can only pick one of each type.

The 6 different combos are shown in  list 2  

List 1 is not correct because you can choose one vegetable only, and not have both.

----------

Look through list 2 and circle the options that say "ham, carrots" and "turkey, carrots". There are 2 items that are circled. This is out of 6 total.

We arrive at the probability 2/6 = 1/3

The fraction 2/6, aka 1/3, is located at the halfway point between 1/6 and 1/2. This is because 1/6+1/2 = 1/6+3/6 = 4/6, which divides in half to get 2/6.

See the diagram below.

The container holds more than 3 cups of sugar, since it holds 3 times the amount used in the recipe.

To calculate the amount of sugar in the container, we need to first determine the amount used in the recipe. The recipe calls for 2 1/3 cups of sugar. This can be converted to a decimal by dividing by 3, resulting in 2.333 cups of sugar used in the recipe. Now that we know the amount used, we can calculate the amount the container holds.

1. 2 1/3 cups = 2.33 cups

2. 3 x 2.33 cups = 6.99 cups

The container holds 3 times the amount used, so we can multiply 2.333 cups by 3, resulting in 6.999 cups of sugar in the container. This is more than 3 cups of sugar, so the container holds more than 3 cups of sugar.

Step-by-step explanation:

Given inequality:

[tex]\dfrac{1}{5}(m-5)\leq \dfrac{1}{10}(m-20)[/tex]

To solve the inequality, multiply both sides by 10:

[tex]\implies \dfrac{10}{5}(m-5)\leq \dfrac{10}{10}(m-20)[/tex]

[tex]\implies2(m-5)\leq m-20[/tex]

Expand the left side:

Subtract m from both sides:

[tex]\implies m-10 \leq -20[/tex]

Add 10 to both sides:

[tex]\implies m \leq -10[/tex]

Therefore, the true solution set to the given inequality are values of m that are less than or equal to -10.  

Therefore, the integers in the given set that make the inequality false are the values of m that are greater than -10:

The solution for the equations is at x = -1 and y = -3.

2: the system of equations has the same slope and the same y-intercept so the system of equations has infinitely many solutions.

When an algebraic equation is graphed, it always results in a straight line since each term in a linear equation has an exponent of 1. For this reason, it is referred to as a "linear equation."

There are both one-variable and two-variable linear equations.

Given the equations,

-2x + 4y = -10

2x + 2y = -8

adding both the equations so -2x and +2x will be eliminated

-2x + 4y + 2x + 2y = -10 - 8

6y = -18

y = -18/6

y = -3

substitute the value of y in equation 2x + 2y = -8

2x + 2(-3) = -8

2x = -8 + 6

x = -1

2: Given equations y = -x + 5 .........(1)

y + x = 5 .........(2)

equation 2 can be written as,

Numbers are mathematical objects used for counting, measuring, and labeling. The original example is the natural numbers 1, 2, 3, 4, etc. [1] Numbers can be linguistically represented by numerals. More generally, individual numbers can be represented by symbols called digits. For example, "5" is the number representing the number five. Since only a relatively small number of symbols can be remembered, basic numbers are usually organized into number systems, which are systematic ways of representing each number. The most common number system is the Hindu-Arabic number system, which can represent any number using combinations of 10 basic numeral symbols called digits.  In common parlance, a number is indistinguishable from the number it represents.

Greater than Number:

It is a mathematical term used to compare two quantities and to establish a relationship between two quantities in which one term is greater than the other. The terms greater than, less than, and equal are used to compare two numbers, amounts, or amounts. Each term has a separate letter. B. "greater than" is represented by ">", "equal to" is represented by "=", and "less than" is represented by "<".

There are 4 rows of Soprano. The concept of algebraic manipulation is used to solve the problem.

Given the information that there are 64 fingers in total and 8 fingers in each row of the Tenor, I was able to determine that there are 32 fingers in the Tenor rows by multiplying 8 fingers/row x 4 rows.

Then, We subtracted the number of fingers in the Tenor rows (32 fingers) from the total number of fingers (64 fingers) to find the number of fingers in the Soprano rows, which is also 32 fingers.

Finally, We divided the number of fingers in the Soprano rows by the number of fingers per row (8 fingers/row) to find the number of rows of Soprano, which is 4 rows.

If there are 64 fingers in total and 8 fingers in each row of the Tenor, then there are 8 fingers / row x 4 rows = 32 fingers in the Tenor rows.

Since there are 64 fingers in total and 32 fingers in the Tenor rows, then there are 64 fingers - 32 fingers = 32 fingers in the Soprano rows.
