(a) When [tex]x=-2, 2^x = 2^(-2) = 1/2^2 = 1/4[/tex]. So, the expression 2^x when x=-2 is 1/4.

(b) When [tex]x=3, 2^x = 2^3 = 8[/tex]. So, the expression 2^x when x=3 is 8.

The expression 2^x represents exponential growth, where the base 2 is multiplied by itself x number of times. When x is a negative number, the expression becomes a fraction because we are dividing 1 by the base raised to the absolute value of x. In this case, 2^(-2) is equivalent to 1/2^2, which is equal to 1/4. On the other hand, when x is a positive number, the expression grows exponentially. When x=3, the expression becomes 2^3, which is equal to 2x2x2 = 8.

In summary, the evaluation of 2^x when x is a negative number produces a fraction, whereas when x is a positive number, it produces a positive integer.

The concept of the unit circle is presented throughout it's answer.

The unit circle is a circle with a radius of 1 unit that is centered at the origin (0,0) of a coordinate plane. It is a fundamental concept in trigonometry and geometry, and it is used to define the trigonometric functions (sine, cosine, and tangent) of angles in the Cartesian plane.

The format of each coordinate on the unit circle is given as follows:

[tex](\cos{\theta}, \sin{\theta})[/tex].

Hence we can calculate the trigonometric measures for any angle, as the tangent, the secant, the cossecant and the cotangent of an angle are all functions of the sine and the cosine obtained by the unit circle.

After deducting a commission of 1.5%, Brian will receive 155.71 pounds in exchange for R2100.

To find out how many pounds Brian will get, we first need to calculate the amount of commission he will pay. The commission is 1.5% of R2100, which is equal to 0.015 x R2100 = R31.50.

The amount of money he will actually receive in pounds is the remaining R2100 minus the commission, which is R2068.50. To convert this to pounds, we multiply by the exchange rate of R1 = 0.075199 pound:

2068.50 x 0.075199 = 155.706675 pounds

Therefore, Brian will get 155.71 pounds for R2100 after paying the agent commission.

Since 4 and 5 have a least common denominator of 20, we can convert both fractions to have a denominator of 20:

-17/4 * 5/5 = -85/20, 32/5 * 4/4 = 128/20, -85/20 - 128/20 = -213/20

A fraction is referred to as the portion of a whole in mathematics. For instance, if a pizza is cut into four equal pieces, each one is represented by a quarter. Fractions make calculations quicker and easier by making it easier to distribute and judge numbers. The depiction of fractions appears easier than when decimal values are used.

A fraction is used to denote a portion or component of a whole. It stands for the proportionate pieces of the whole. The numerator and denominator are the two components that make up a fraction. The numerator is the number at the top, and the denominator is the number at the bottom.

To simplify:

-4 and 1/4 - 6 and 2/5

For the two mixed integers, we must identify a common denominator. The least frequent multiple of 4 and 5 is 20 since their prime components are 2 and 5. Both mixed numbers can be transformed into improper fractions with a denominator of 20 as follows:

-4 and 1/4 = -17/4

6 and 2/5 = 32/5

Now we can subtract these fractions:

-17/4 - 32/5

We must locate a common denominator in order to subtract fractions. Since 4 and 5 have a least common denominator of 20, we can convert both fractions to have a denominator of 20:

-17/4 * 5/5 = -85/20

32/5 * 4/4 = 128/20

We can now take the two fractions apart:

-85/20 - 128/20 = -213/20

Therefore, -4 and 1/4 - 6 and 2/5 simplify to -213/20.

So, the answer is negative 213 over 20.

Answer:

a. An absolute value inequality that represents the possible actual temperature t is:

|t - 72| < 2

b. To find the range of possible actual temperatures, we can solve the inequality:

|t - 72| < 2

We can split this into two separate inequalities, one for when t is greater than 72 and one for when t is less than 72:

t - 72 < 2 and -(t - 72) < 2

Simplifying these inequalities, we get:

t < 74 and t > 70

Therefore, the range of possible actual temperatures is 70°F < t < 74°F.

The calculated equation that represents a line parallel to y = -2x + 4 is (c) -2x - y = 3.

The equation of a line that is parallel to y = -2x + 4 will have the same slope as -2 since parallel lines have the same slope.

Therefore, we need to look for an equation that has a slope of -2.

(a) 1/2x + y = 1 has a slope of -1/2, which is not equal to -2. Thus, it is not parallel to y = -2x + 4.

(b) -2x + y = 8 has a slope of 2, which is not equal to -2. Thus, it is not parallel to y = -2x + 4.

(c) -2x - y = 3 can be rearranged to y = -2x - 3, which has a slope of -2, so it is parallel to y = -2x + 4.

(d) -1/2x + y = 5 has a slope of 1/2, which is not equal to -2. Thus, it is not parallel to y = -2x + 4.

Therefore, the equation that represents a line parallel to y = -2x + 4 is (c) -2x - y = 3.

To find all the real zeros of a polynomial function algebraically, use the Rational Root Theorem to generate a list of possible rational zeros and use synthetic division to test each possible zero. The zeros that remain after testing all the possible zeros are the real zeros of the polynomial function.

To find all the real zeros of a polynomial function algebraically, you can use the Rational Root Theorem and synthetic division. The Rational Root Theorem states that if a polynomial function has integer coefficients, then any rational zero (i.e., a zero that can be expressed as a fraction) must have a numerator that is a factor of the constant term and a denominator that is a factor of the leading coefficient.

Here are the steps you can follow:

1. Write the polynomial function in descending order of degree, with all like terms combined.

2. Use the Rational Root Theorem to generate a list of possible rational zeros. This list will be a set of all the possible fractions that can be formed by dividing a factor of the constant term by a factor of the leading coefficient.

3. Use synthetic division to test each possible zero. Start with the smallest possible denominator and work your way up. If a possible zero is not a zero of the polynomial function, cross it off the list.

4. Repeat step 3 until all the possible zeros have been tested. The zeros that remain are the real zeros of the polynomial function.

For example, let's say we have the polynomial function f(x) = x^3 - 6x^2 + 11x - 6.

Write the polynomial function in descending order of degree: f(x) = x^3 - 6x^2 + 11x - 6.

Use the Rational Root Theorem to generate a list of possible rational zeros: ±1, ±2, ±3, ±6.

Use synthetic division to test each possible zero. We start with x = 1:

1 │ 1 -6 11 -6

│ 1 -5 6

└─────────────

1 -5 6 0

Since the remainder is zero, we have found a zero of the polynomial function at x = 1. We can write the factorization f(x) = (x - 1)(x^2 - 5x + 6).

Now we use synthetic division to test the other possible zeros:

2 │ 1 -6 11 -6

│ 2 12 46

└─────────────

1 -4 23 40

x = 2 is not a zero of the polynomial function.

3 │ 1 -6 11 -6

│ 3 15 78

└─────────────

1 -3 26 72

x = 3 is not a zero of the polynomial function.

-1 │ 1 -6 11 -6

│ -1 7 -4

└────────────

1 -7 18 -10

x = -1 is not a zero of the polynomial function.

-2 │ 1 -6 11 -6

x = -2 is not a zero of the polynomial function.

A table that represents a linear function include the following: A.

x −4 −2 0 2 4

y   5 1 −3 −7 −11

In Mathematics, a linear function can be defined as a type of function whose equation is graphically represented by a straight line on the cartesian coordinate.

This ultimately implies that, a linear function has the same (constant) slope and it is typically used for uniquely mapping an input variable to an output variable, which both increases simultaneously.

Next, we would determine the slope by using the points contained in the table as follows;

Slope (m) = (Change in y-axis, Δy)/(Change in x-axis, Δx)

Slope (m) = (y₂ - y₁)/(x₂ - x₁)

Slope (m) = (1 - 5)/(-2 + 4) = (-3 - 1)/(0 + 2) = (-7 + 3)/(2 - 0)

Slope (m) = -2.

Expanding the right-hand side, we get:

[tex]x + 8 = 3x + 12[/tex]

Subtracting x and 8 from both sides, we get:

[tex]2x = -4[/tex]

Dividing both sides by 2, we get:

[tex]x = -2[/tex]

Therefore, the solution to the given equation is x = -2. We can check this solution by substituting x = -2 into the original equation and verifying that both sides are equal.

The equation of the given circle is: (x - 5)² + (y+ 1)² = 256

The length of side 2 of the given triangle is 16.22.

The Law of Cosines is a mathematical formula that is used to calculate the length of sides and angles in a triangle. It is based on the Pythagorean theorem, which states that the square of the length of the hypotenuse of a right triangle is equal to the sum of the squares of the other two sides

The Law of Cosines helps to solve for the side length in triangles when we are given two sides and the angle between them. In this triangle we are given side 1 (15) and the angle between the two sides (33°). To find side 2, we will use the formula:

c² = a² + b²- 2ab*cosC

Where c is the length of the unknown side, a is the length of the given side, b is the length of the other given side, and C is the angle between the two given sides.

In this case, c is side 2, a is 15, b is unknown, and C is 33°. We will plug in the known values and solve for b:

b² = 15² + c² - 2*15*c*cos(33°)

b² = 225 + c² - 30c*cos(33°)

We can solve this equation for c:

c = (225 + b² - 30b*cos(33°))/2

Now, we can solve for b using the values for c and a given in the problem:

b²= 225 + 27² - 30*27*cos(33°)

b² = 225 + 729 - 690.8

b²= 264.2

b = 16.22

Therefore, the length of side 2 is 16.22.
