Step-by-step explanation:

[tex]P+Q-R=(2x^2+3xy-5y^2)+(-5x^2+2xy+3y^2)-(-3x^2+5xy-2y^2)[/tex]

                  [tex]=2x^2+3xy-5y^2-5x^2+2xy+3y^2+3x^2-5xy+2y^2[/tex]

                  [tex]=2x^2-5x^2+3x^2-5y^2+3y^2+2y^2+3xy+2xy-5xy[/tex]

                  [tex]=0[/tex]

Answer:

To show that P + Q - R = 0, we need to substitute the expressions for P, Q, and R into the equation and simplify.

P + Q - R = (2x² + 3xy - 5y²) + (-5x² + 2xy + 3y²) - (-3x² + 5xy - 2y²)

Simplifying the brackets on the right-hand side:

P + Q - R = 2x² + 3xy - 5y² - 5x² + 2xy + 3y² + 3x² - 5xy + 2y²

Grouping like terms together:

P + Q - R = (2x² - 5x² + 3x²) + (3xy + 2xy - 5xy) + (-5y² + 3y² + 2y²)

Simplifying the expressions in the brackets:

P + Q - R = 0x² + 0xy + 0y²

Therefore, P + Q - R = 0.

The measure of the sector that represents the probability of the medicine curing one person is 216°. So correct option is A.

In geometry, a sector is a region of a circle enclosed by two radii and an arc. The two radii form an angle, called the central angle, which defines the boundary of the sector.

The area of a sector can be calculated using the following formula:

Area of sector = (central angle / 360) * π * r²

where:

central angle is the angle formed by the two radii

r is the radius of the circle

π is the mathematical constant pi, which is approximately 3.14159

The perimeter of a sector is the sum of the length of the arc and the length of the two radii. The length of the arc can be calculated using the formula:

Length of arc = (central angle / 360) * 2 * π * r

Sectors are often used in real-world applications, such as calculating the area of a pizza slice or the distance traveled by a car in a circular racetrack. They are also used in trigonometry to calculate angles and side lengths of triangles formed by intersecting chords and tangents in circles.

The probability of the medicine curing one person is given by P(curing) = 3/5. Since the spinner is a circle of 360°, the measure of the sector that represents the probability of the medicine curing one person is:

360° × P(curing) = 360° × 3/5 = 216°

Step-by-step explanation:

The function based on the given parent function and transformations in the given order would be:

f(x)= -1/2√(x+2)

Functions are often represented as equations, graphs, or tables, and they are used to model a wide range of real-world phenomena. For example, a function might describe the relationship between the time of day and the temperature outside, or the amount of money earned based on the number of hours worked.

Let's break down how each transformation affects the parent function:

Shifting units to the left: This transformation involves replacing the variable "x" with "x+2" in the parent function. This has the effect of shifting the graph 2 units to the left. The function becomes:

f(x)= √(x+2)

Stretching horizontally: This transformation involves replacing "x" with "2x" in the function obtained after the first transformation. This has the effect of stretching the graph horizontally by a factor of 1/2. The function becomes:

f(x)= √(2x+4)

Reflecting across the x-axis: This transformation involves multiplying the entire function by -1. This has the effect of reflecting the graph across the x-axis. The function becomes:

f(x)= -√(2x+4)

So the final function based on the given parent function and transformations in the given order is:

f(x)= -1/2√(x+2)

As a result, the expression can be expressed in the following standard form: -32 sin(102) + 32i cos = 32i (cos(102) + I sin(102)) (102).

In mathematics, programming, or other subjects, an expression is typically a grouping of numbers, symbols, and operators that denotes a value or computation. When used to indicate a mathematical relationship or formula, an expression in mathematics can be made up of a number of different variables, operators, and digits. For instance, the statement 3x + 2y denotes a linear equation. A combination of variables, constants, operators, and functions can make up an expression in programming, which can then be evaluated to create a value. For instance, the expression 5 + 3 evaluates to 8 as an expression.

given

First, we can use De Moivre's theorem to simplify the expression:

(cis(22.5+67.5)) = (cis(22.5+67.5)) = cis(22.5+90) = I

We then have:

Cos(12) + I sin(12) = 32cis (12)

When we multiply these two outcomes, we obtain:

32i cis(90+12) = 32i cis(i * 32cis(12)) = 32i cis102

Thus, the phrase can be worded as follows:

(cis22.5) (5cis67.5) (5cis67.5) 32(cos (12) + I sin (12)) = 32i cis (102).

Using Euler's formula, cis102 can be written as follows:

102 + I sin + cos(102) = cis102 (102)

As a result, the expression can be expressed in the following standard form: -32 sin(102) + 32i cos = 32i (cos(102) + I sin(102)) (102)

The final response is thus: Z = 32i cos + 32sin(102) (102)

Therefore, we cannot calculate the cost of an ounce of insulin in 2006 using this function. (a). the cost of insulin increases by 12% per year.

(b).Therefore, an ounce of insulin would have cost approximately $114.08 in 2018.

(c).Therefore, the cost of insulin increases by 12% per year.

What is function?

a function is a relationship between two sets of objects, where each object in the first set (called the domain) is associated with exactly one object in the second set (called the range). The domain and range can be any set, including numbers, geometric shapes, or other mathematical objects.

A function is typically represented by a rule or formula that describes how to map each element in the domain to an element in the range. For example, the function f(x) = 2x maps each value of x to its double, so that f(1) = 2, f(2) = 4, f(3) = 6, and so on.

The cost of insulin increases over time because the value of 1.12 is greater than 1, meaning the function's output grows with increasing t. To find the percentage increase per year, we can calculate the difference in cost between two consecutive years and divide it by the cost of the earlier year. For example, to find the percentage increase between 2010 and 2011:

[tex]c(1) - c(0) = 54(1.12) - 54 = 6.48[/tex]

Percentage increase = (6.48/54) x 100% = 12%

Therefore, the cost of insulin increases by 12% per year.

b. To find the cost of an ounce of insulin in 2018, we need to find the value of t for that year. Since t represents the number of years since 2010, we can subtract 2010 from 2018 to get:

[tex]t = 2018 - 2010 = 8[/tex]

[tex]c(8) = 54(1.12)^8 =$114.08[/tex]

Therefore, an ounce of insulin would have cost approximately $114.08 in 2018.

c. To find the cost of an ounce of insulin in 2006, we need to find the value of t for that year. Since t represents the number of years since 2010, we can subtract 2010 from 2006 to get:

[tex]t = 2006 - 2010 = -4[/tex]

However, a negative value of t is not meaningful in this context because the function assumes t represents the number of years since 2010. Therefore, we cannot calculate the cost of an ounce of insulin in 2006 using this function.

The rate at which the amount of water in the tank is changing is -0.5 gallons/minute. This means that the amount of water in the tank is decreasing at a rate of 0.5 gallons per minute.

The rate of change is a measure of how a quantity changes with respect to another quantity. It tells us how much a particular quantity is changing for a given change in another quantity.

It is often represented as a ratio of the change in the quantity of interest to the change in the other quantity, usually with units of measurement.

Here we have

Ms. Grimes walks up to a tank of water that can hold up to 12 gallons.

When it is active, a drain empties water from the tank at a constant rate. When Jada first sees the tank it contains 8 gallons of water. Four minutes later the tank contains 6 gallons of water.

We can use the following formula for the rate of change of a quantity:

Rate of change = (change in quantity) / (change in time)

Given that when Jada first saw the tank, 8 gallons. Four minutes later, the amount of water in the tank decreased to  6 gallons.

So the change in the amount of water in the tank is:

change in water = 6 gallons - 8 gallons = -2 gallons

The change in time is:

change in t = 4 minutes - 0 minutes = 4 minutes

So, the rate of change of the amount of water in the tank is:

= (change in W) / (change in t)

= (-2 gallons) / (4 minutes) = -0.5 gallons/minute

Therefore,

The rate at which the amount of water in the tank is changing is -0.5 gallons/minute. This means that the amount of water in the tank is decreasing at a rate of 0.5 gallons per minute.

Yes, (x - 4) is a factor of polynomial function P(x) = x⁵ + 4x⁴ - 17x³ - 60x².

Step-by-step explanation:

The Factor Theorem states that if f(x) is a polynomial, and f(a) = 0, then (x - a) is a factor of f(x).

Therefore, according to the Factor Theorem, if (x - 4) is a factor of P(x) then P(4) = 0.

To determine if (x - 4) is a factor of P(x), substitute x = 4 into the function and solve.

[tex]\begin{aligned}x=4 \implies P(4)&=(4)^5+4(4)^4-17(4)^3-60(4)^2\\&=1024+4(256)-17(64)-60(16)\\&=1024+1024-1088-960\\&=2048-1088-960\\&=960-960\\&=0\end{aligned}[/tex]

The solution for ‘d’ in the given equation is d = (ln(A) - ln(B))/ln(1+c/d).

Natural log is a logarithmic function commonly used in mathematics and in calculators to simplify equations. It is the inverse of the exponential function and is written as ln(x).

In order to solve for ‘d’ in the given equation, we need to isolate it on the left side of the equation.

To do this, we can begin by taking the natural log of both sides of the equation, as shown below.

ln(A) = ln(B) + d*ln(1+c/d)

We can now rearrange the terms in this equation such that ‘d’ is isolated on the left side of the equation.

d*ln(1+c/d) = ln(A)-ln(B)

We can now divide both sides of the equation by ln(1+c/d) in order to solve for ‘d’, as shown below.

d = (ln(A) - ln(B))/ln(1+c/d)

Therefore, the solution for ‘d’ in the given equation is

d = (ln(A) - ln(B))/ln(1+c/d).

A logarithm is a mathematical function that measures the relationship between two quantities, by expressing one quantity in terms of another. More specifically, a logarithm is the power to which a base must be raised to produce a given number.

a) [tex]2^(A) * 2^(B) = 2^0[/tex] can be rewritten as [tex]2^(A+B) = 2^0[/tex].

To find the values of A and B, we need to solve the equation [tex]2^(A+B) = 2^0\\[/tex].

Since [tex]2^0[/tex] = 1, we have [tex]2^(A+B)[/tex] = 1, which means A + B = 0. One possible solution is A = -1 and B = 1, since (-1) + 1 = 0.

Therefore, the equation becomes [tex]2^(-1) * 2^1 = 2^0[/tex], which is true.

(A) = -1

(B) = 1

b) [tex](2^3)/(2^(C)) = 2^(D)[/tex] can be simplified as [tex]2^(3-C) = 2^(D)[/tex].

To find the values of C and D, we need to set the exponents equal to each other. So, we have 3 - C = D, which means C = 3 - D.

One possible solution is C = 3 and D = 0, since 3 - 0 = 3.

Therefore, the equation becomes [tex](2^3)/(2^3) = 2^0[/tex], which is true.

(C) = 3

(D) = 0

c) [tex]2^(-3) * (E)^(-3) = 10^(F)[/tex] can be rewritten as [tex](1/2^3) * (1/E^3) = 10^F[/tex]. Multiplying both sides by [tex]2^3 * E^3[/tex], we get [tex]1 = 10^F * 2^3 * E^3[/tex].

Taking the logarithm of both sides, we get log(1) = [tex]log(10^F * 2^3 * E^3)[/tex]. Since log(1) = 0, we have 0 = F log(10) + 3log(2) + 3log(E), which simplifies to F = -2 - 3log(E)/log(10) with one possible solution of E = 5 and F = -2. Therefore, the equation becomes [tex]2^(-3) * 5^(-3) = 10^(-2)[/tex], which is true.
