What is a root in mathematics?
In mathematics, a number's "root" is a number that, when multiplied by itself, equals the original number; alternatively, a number's "root" can also be an equation's solution, which is typically presented as a number or an algebraic formula.

For instance, since 7*7=49, the square root of 49 is 7. In this instance, 7 is referred to as the square root of 49 since it must be multiplied twice to produce the number. 3 because 3*3*3=27 is the cube root of 27. Since 27 is obtained by multiplying 3 by three, we refer to this as a cube root, so 3 is the cube root of 27.

If the miniature town is built to a 1:10 scale, the diameter of a chocolate chip cookie from Faragher's bakery would be 0.35 inches in the miniature town.

In the miniature town at the Behringer Crawford Museum, the diameter of a chocolate chip cookie from Faragher's bakery would depend on the scale of the miniature town. Since the video doesn't provide the specific scale, we'll have to make an assumption.

Let's say the miniature town is built to a 1:10 scale, meaning that objects in the town are 1/10th the size of their real-life counterparts. If a typical chocolate chip cookie has a diameter of 3.5 inches, we can calculate the diameter of the miniature cookie by dividing 3.5 inches by 10:

3.5 inches / 10 = 0.35 inches

Therefore, if the miniature town is built to a 1:10 scale, the diameter of a chocolate chip cookie from Faragher's bakery would be 0.35 inches in the miniature town.

However, it's important to note that without knowing the specific scale of the miniature town, we can only make assumptions based on the given information. The actual diameter of the chocolate chip cookie in the miniature town may vary depending on the scale chosen for the model.

Step 1: We have the next system of equations -

\(2x - 3y = 13\)

\(x + 2y = 4\)

Step 2: Now, we will multiply by -2 the second equation:-

\( - 2(x + 2y) = 4\)

\(→ - 2x - 4y = - 8\)

Step 3: Then we add it :-

\(2x - 3y = 13\)

\(( + ) \: - 2x - 4y = - 8\)

Step 4: After finding the sum, we simplify:-

\( - 7y = 5\)

\(→y = - \frac{5}{7} \)

Then, substitute the above y value to find x's value in any equation of Step 1. Now, I used to second equation in Step 1:-

\(x = - 2( \frac{ - 5}{7}) + 4\)

Step 5: Then simplify :-

\(y = \frac{38}{7} \)

Therefore, the final answer is :-

\(x = \frac{38}{7} \)

Answer:

Option A

Step-by-step explanation:

The set of values for which y is a function of x is the set where each x-value has exactly on y-value. No x-value has more than 1 y-value.

✅Option A: y is A FUNCTION of x because it has exactly one y-value assigned to each x-value.

❌Option B: y is NOT a function of x because there are two y-values, 4 and 2, that are assigned to one x-value, -1.

❌Option C: y is NOT a function of x because there are two y-values, 10 and 12, that are assigned to one x-value, 1.

❌Option D: y is NOT a function of x because there are two y-values, 2 and 4, that are assigned to one x-value, -1.

For the given equation 4x + 3y =21 the slope intercept form is given by y = (-4/3)x + 7.

Graph is attached.

As given in the question,

Given equation is equal to :

4x + 3y = 21

To get the slope intercept form of the given equation we have,

Subtract 4x from both the sides of the given equation we have,

4x + 3y - 4x = 21 - 4x

⇒ 3y = 21 - 4x

Now divide by 3 on both the sides of the equation we get,

3y / 3 = (-4/3)x + (21/3)

⇒ y = (-4/3) x + 7

Graph of the given equation in slope intercept form y = (-4/3) x + 7 is attached.

When x = 0 ⇒ y = 7

y= 0 ⇒ x = 21 /4

Therefore, for the given equation 4x + 3y =21 the slope intercept form is given by  y = (-4/3)x + 7.

No subject is off-limits when sociologists use the sociological lens and start asking questions. Every facet of human behaviour has the potential to be studied. Sociologists cast doubt on the society that people have built and inhabit. They observe behavioral patterns as individuals navigate that world.

\((x+4)^2+(y-3)^2=149\)

Step-by-step explanation:

The equation of a circle is \((x-h)^2+(y-k)^2=r^2\) where \((h,k)\) is the center of the circle and \(r\) is the radius of the circle.

Given that \((h,k)\rightarrow(-4,3)\) and it passes \((6,-4)\), their distance between each other must the radius of the circle, so we can use the distance formula to find the radius:

\(d=\sqrt{(y_2-y_1)^2+(x_2-x_1)^2}\\\\d=\sqrt{(-4-3)^2+(6-(-4))^2}\\\\d=\sqrt{(-7)^2+10^2}\\\\d=\sqrt{49+100}\\\\d=\sqrt{149}\)

Therefore, if the length of the radius is \(r=\sqrt{149}\) units, then \(r^2=149\), making the final equation of the circle \((x+4)^2+(y-3)^2=149\)

The value of g(x) where g(x) is the translation 4 units up of \(f(x) = x^2 is (x + 2)^2.\)

To find g(x), the translation 4 units up of \(f(x) = x^2\), we need to add 4 to the function f(x).

g(x) = f(x) + 4

\(g(x) = x^2 + 4\)

To write the answer in the form \(a(x - h)^2 + k\), where a, h, and k are integers, we need to complete the square for g(x).

\(g(x) = x^2 + 4\)

\(g(x) = 1(x^2) + 4\\g(x) = 1(x^2) + 2(2x) + (2^2) - (2^2) + 4\\g(x) = (x^2 + 2(2x) + 2^2) - 4 + 4\\g(x) = (x^2 + 2(2x) + 2^2) + 0\\g(x) = (x + 2)^2 + 0\\\)

The value of the function g(x) when  is the translation 4 units up of f(x) = x^2 is g(x) = (x - 0)^2 + 4

The function g(x) is obtained by translating the function f(x) = x^2 four units up.

To achieve this translation, we add 4 to the original function f(x).

g(x) = f(x) + 4

= x^2 + 4

Now, let's write the expression x^2 + 4 in the form a(x - h)^2 + k.

To do this, we complete the square:

g(x) = x^2 + 4

= (x^2 + 0x) + 4

= (x^2 + 0x + 0^2) + 4 - 0^2

= (x^2 + 0x + 0^2) + 4

Now, we can rewrite it as a perfect square:

g(x) = (x^2 + 0x + 0^2) + 4

= (x + 0)^2 + 4

Simplifying further, we have:

g(x) = (x - 0)^2 + 4

= (x - 0)^2 + 4

Therefore, g(x) = (x - 0)^2 + 4 is the desired form, where a = 1, h = 0, and k = 4.

Answer:

240 cm²

Step-by-step explanation:

Split the shape into a trapezoid (top half) and a rectangle (bottom half).

Area of a rectangle = width x length

⇒ area = 6.5 x 20 = 130 cm²

\(\textsf{Area of a trapezoid} = \frac{1}{2}(a+b)h\)

(where a and b are the lengths of the base and top, and h is the height)

⇒ \(\textsf{area} = \frac{1}{2}(20+20)\times5.5\)

⇒ area = 110 cm²

Total area = area of rectangle + area of trapezoid

⇒ area = 130 + 110 = 240 cm²

The answer of the given question based on the assuming that the spins are independent, the pmf of x is P(x = k) = (2/3)^(k-1) * (1/3).

Probability is a measure of likelihood or chance that specific event will occur. It is  branch of mathematics that deals with study of random events and their associated outcomes.

In probability theory, events are typically represented as sets of possible outcomes, and probabilities are assigned to these events based on likelihood of their occurrence. The probability of  event is  number between 0 and 1, where 0 represents  impossible event and 1 represents certain event.

Let's denote the probability of getting a 3 on any given spin as p. Since the spinner only has three numbers, the probability of getting a 3 on any given spin is 1/3.

Now, let's consider the probability distribution of x, the number of spins until the first 3 occurs. The probability that x = 1 is simply the probability of getting a 3 on the first spin, which is p = 1/3.

The probability that x = 2 is the probability of not getting a 3 on the first spin (which is 2/3), multiplied by the probability of getting a 3 on the second spin (which is p = 1/3). So:

P(x = 2) = (2/3) * (1/3) = 2/9

Similarly, the probability that x = 3 is the probability of not getting a 3 on the first two spins (which is (2/3)^2), multiplied by the probability of getting a 3 on the third spin (which is p = 1/3). So:

P(x = 3) = (2/3)²* (1/3) = 4/27

In general, the probability that x = k (where k is a positive integer greater than or equal to 1) is the probability of not getting a 3 on the first k-1 spins (which is (2/3)^(k-1)), multiplied by the probability of getting a 3 on the kth spin (which is p = 1/3). So:

P(x = k) = (2/3)^(k-1) * (1/3)

This is the pmf (probability mass function) of x, the number of spins until the first 3 occurs.

The power to which a number or expression is raised is called the exponent.

1. An exponent is a mathematical notation that represents the power to which a number or expression is raised. It is written as a superscript number or variable placed above and to the right of the base number or expression.

2. The base number or expression is the number or expression that is being multiplied repeatedly by itself, raised to the power of the exponent.

3. The exponent tells us how many times the base number or expression should be multiplied by itself. For example, in the expression \(2^3\), the base is 2 and the exponent is 3. This means that 2 should be multiplied by itself three times: 2 * 2 * 2 = 8.

4. The exponent can be a positive whole number, a negative number, zero, or a fraction. Each of these cases has different interpretations:

  - Positive exponent: Indicates repeated multiplication. For example, \(2^4\)means 2 multiplied by itself four times.

  - Negative exponent: Indicates the reciprocal of the base raised to the positive exponent. For example, \(2^{-3\) means 1 divided by \(2^3\).

  - Zero exponent: Always equals 1. For example, \(2^0\) = 1.

  - Fractional exponent: Represents a root. For example, \(4^{(1/2)\)represents the square root of 4.

5. Exponents follow certain mathematical properties, such as the product rule \((a^m * a^n = a^{(m+n)})\), the quotient rule \((a^m / a^n = a^{(m-n)})\), and the power rule \(((a^m)^n = a^{(m*n)})\).

The given mathematical expression is evaluated for the input values (2, 4). The result of the expression is calculated using various operations such as addition, multiplication, square root, natural logarithm, minimum, maximum, and function composition.

The expression f(x1, x2) involves several mathematical operations. Let's evaluate each part of the expression step by step:

1. The first term is 421 + 222, which equals 643.

2. The second term is 3x² + 213. Plugging in x1 = 2 and x2 = 4, we get 3(2)² + 213 = 3(4) + 213 = 12 + 213 = 225.

3. The third term is 5x11². Substituting x1 = 2 and x2 = 4, we have 5(2)(11)² = 5(2)(121) = 1210.

4. The fourth term is (√₁+√₂)². Replacing x1 = 2 and x2 = 4, we obtain (√2 + √4)² = (1 + 2)² = 3² = 9.

5. The fifth term is 10ln(₁). Plugging in x1 = 2, we have 10ln(2) = 10 * 0.69314718 ≈ 6.9314718.

6. The sixth term is (x₁+x₂)(x² + x3). Substituting x1 = 2 and x2 = 4, we get (2 + 4)(2² + 4³) = 6(4 + 64) = 6(68) = 408.

7. The seventh term is min(3r1, 10√2). As we don't have the value of r1, we cannot determine the minimum between 3r1 and 10√2.

8. The eighth term is max{5x1,2r2}. Since we don't know the value of r2, we cannot find the maximum between 5x1 and 2r2.

9. Finally, we have MP1(x1, x2), MP2(X1, X2), and TRS(x1, x2), which are not defined or given.

Considering the given expression, the evaluated terms for the input values (2, 4) are as follows:

- 421 + 222 = 643

- 3x² + 213 = 225

- 5x11² = 1210

- (√₁+√₂)² = 9

- 10ln(₁) ≈ 6.9314718

- (x₁+x₂)(x² + x3) = 408

The terms involving min() and max() cannot be calculated without knowing the values of r1 and r2, respectively. Additionally, MP1(x1, x2), MP2(X1, X2), and TRS(x1, x2) are not defined.
