Answer: So after solving and simplifying terms equation is\(x^4+10x^3-47x^2-360x+1296\)

Step-by-step explanation: Given we have two equations f(x) =\(x^{2} +4x-32\) and g(x) = \(x-4\)

we have been asked to find ( f +g)(x) that is f(x)+g(x)

So first we add them \(x^{2} +4x-32 + x-4\)

So we have an equation that is: \(x^{2} +5x-36\)

Then we need to multiply both

\((x^2+5x-36)(x^2+5x-36)\)

So we get\(\left(x^2+5x-36\right)^2\)

Distribute parentheses

\(x^2x^2+x^2\cdot \:5x+x^2\left(-36\right)+5xx^2+5x\cdot \:5x+5x\left(-36\right)-36x^2-36\cdot \:5x-36\left(-36\right)\)

On simplifying

\(x^4+10x^3-47x^2-360x+1296\)

So standard form of result is \(x^4+10x^3-47x^2-360x+1296\) .

Complete question:

Write a M function file 'tconvert.m', which can convert from Cartesian coordinates (x,y) into Polar coordinates.

Answer: Choice C

x+y = 28

3x+4y = 100

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

Explanation:

x and y are placeholders for nonnegative whole numbers.

Specifically,

x = number of three point questions

y = number of four point questions

Since we have 28 questions total, this must mean x+y = 28. That forms the first equation in our system of equations.

------------

Now let's form the second equation:

x = number of three point questions

3x = points we get from all the three point questions

y = number of four point questions

4y = points we get from all the four point questions

3x+4y = all points possible

3x+4y = 100  is the second equation

------------

So we have this system

\(\begin{cases}x+y = 28\\3x+4y = 100\end{cases}\)

which fits the conditions in the instructions.

The function "fig" is not defined in the given information, without its definition, we cannot determine the domain of the function for the given expressions: f(x) = x + 99 & g(x) = x²

(a) (r + g)(x) = r(x) + g(x) = (x - 8) + (x² - 8) = x² + x - 16

(b) (-9)(x) - 8 = - 9x - 8

(c) (f)(x) = f(x) = x + 99(x) = x²(f/g)(x) = f(x) / g(x) = (x + 9) / x

The domain of the given figure is not given, hence we can not find the domain of fig.

f(x) = x + 99

The function f(x) is defined as the sum of x and 99.

g(x) = x²

The function g(x) is defined as the square of x.

(a) (r+g)(x) = ?

The expression (r+g)(x) represents the sum of two functions, r(x) and g(x).

However, the specific definitions of r(x) and the value of x are not provided.

Therefore, we cannot determine the result without more information.

(b) (-9)(x) - ?

The expression (-9)(x) represents the product of -9 and x.

However, a specific value for x is not given, so we cannot compute the result without more information.

(c) (f)(x) = (a)

The expression (f)(x) represents the function f(x).

Since f(x) is defined as x + 99, we have (f)(x) = x + 99.

The result (a) is the same as the function itself, which is x + 99.

(d) (f/g)(x) = ?

The expression (f/g)(x) represents the quotient of two functions, f(x) and g(x).

Therefore, we need to divide f(x) by g(x), which gives us:

(f/g)(x) = (x + 99) / (x²)

(e)The domain of fig:

The function "fig" is not defined in the given information. Without its definition, we cannot determine the domain of the function.

How to get the product of the page

x * (x + 1) = 132

Expanding the equation, we get:

x² + x = 132

To solve for x, we need to rewrite the equation as a quadratic equation:

x²+ x - 132 = 0

Now, we can factor the quadratic equation:

(x - 11)(x + 12) = 0

This equation has two solutions for x:

x = 11

x = -12

Since page numbers cannot be negative, we discard the second solution. Thus, the left-hand page number is 11, and the right-hand page number is 11 + 1 = 12.

Using the surface area formula, the longest side length of a cube Fernanda can make without needing more paint is approximately 0.94 yards (rounded to the nearest tenth of a yard).

What is surface area?

The area is the area occupied by a two-dimensional flat surface. It has a square unit of measurement. The surface area of a three-dimensional object is the space taken up by its outer surface. Square units are used to measure it as well.

We are given that Fernanda has enough paint to cover 5 square yards, so the surface area of the cube she can make without needing more paint is A = 5 square yards.

The formula for the longest side length s of a cube with surface area A is -

s = √(A/6)

Substituting A = 5 in the equation, we get -

s = √(5/6) ≈ 0.94

Therefore, the longest side length of a cube is approximately 0.94 yards.

The correct way to measure the zone of inhibition is to place a known amount of an antimicrobial agent on a solid medium.

Area is a quantity that measures the size of a two-dimensional surface or shape. It is expressed in square units such as square centimetres (cm2), square metres (m2) or square kilometres (km2). Area is used to describe the size of a garden, a house, a room, a city and much more. It can also be used to calculate the amount of material required for a project, such as paint, carpet or tiles. Knowing the area of a shape can help to calculate costs, and to make sure that enough materials are ordered.

The zone of inhibition is then measured as the area surrounding the antimicrobial agent where microbial growth has been inhibited. This area is typically measured in millimeters. To accurately measure the zone of inhibition, it is important to ensure that the size of the inoculum and the amount of antimicrobial agent used remain constant. Additionally, it is important to consider the type of organism being studied, as different organisms can have different levels of susceptibility to the antimicrobial agent. Finally, the medium used should be appropriate for the organism being studied, as different media can produce different results.

Answer:

y = -8/5x + 16

Step-by-step explanation:

The slope-intercept form is y = mx + b

m = the slope

b = y-intercept

The slope = rise/run or (y2 - y1) / (x2 - x1)

Pick 2 points (0,16) (5,8)

We see the y decrease by 8 and the x increase by 5, so the slope is

m = -8/5

The Y-intercept is located at (0,16)

So, the equation is y = -8/5x + 16

(a) The probability of having at least one girl is 1 - 0.0625 = 0.9375 or 93.75%.

(b) The probability that all the children will be of the same gender is 0.0625 + 0.0625 = 0.125 or 12.5%.

The probability of having at least one girl can be calculated by finding the probability of having no girls and subtracting it from 1.

Assuming that the probability of having a boy or a girl is equal (0.5), the probability of having no girls is (0.5)^4 = 0.0625.

Therefore, the probability of having at least one girl is 1 - 0.0625 = 0.9375 or 93.75%.

(b) The probability that all the children will be of the same gender is 0.0625 + 0.0625 = 0.125 or 12.5%.

The probability that all the children will be of the same gender can be calculated by finding the probability of having all boys and adding it to the probability of having all girls.

The probability of having all boys is (0.5)^4 = 0.0625, and the probability of having all girls is also 0.0625.

Therefore, the probability that all the children will be of the same gender is 0.0625 + 0.0625 = 0.125 or 12.5%.

The equation for an ellipse with a focus at (-2, 0) and vertices at (±7, 0) is (x + 2)²/49 + y²/1 = 1.

This equation can be derived by using the fact that the distance between the focus and the vertices of an ellipse is equal to the length of the major axis. Thus, we can calculate the length of the major axis by subtracting the x-coordinate of the focus from the x-coordinate of the vertices (which is 7 - (-2) = 9). This gives us the length of the major axis, which is 9.

Now, we can use the formula for the equation of an ellipse, given by:

(x - h)²/a² + (y - k)²/b² = 1

Where (h, k) is the center of the ellipse and a and b are the lengths of the major and minor axes, respectively. In this case, the center of the ellipse is (0, 0) and the lengths of the major and minor axes are 9 and 1, respectively.

Substituting the values into the equation, we get:

(x + 2)²/49 + y²/1 = 1

Therefore, the equation for an ellipse with a focus at (-2, 0) and vertices at (±7, 0) is (x + 2)²/49 + y²/1 = 1.
