Given f(x) = 3(4-x), what is the value of f( − 2)? Enter your answer in the answer box.​

Step 1: Write out the formula for logistic growth model

Step 2: Write out the given values and substitute them into the formula

Hence,

Hence, the number of plants after 5 months is approximately 112

The expression that represents the combined function of f(x) and g(x) is h(x) = 2x/(5 - x)

From the question, we have the following parameters:

Function f(x) = 2x

Function g(x) = 2 - x + 3

Evaluate the like terms in the equation of the function g(x)

So, we have

g(x) = 5 - x

From the question, we understand that:

The function h(x) is a combination of the functions f(x) and g(x) by division

This can be represented as

h(x) = f(x)/g(x)

The above also implies that the function h(x) is a composite function

Substitute the known values in the above equation

So, we have the equation of the composite function h(x) to be

h(x) = 2x/(5 - x)

Hence, the equation of the composite function h(x) is h(x) = 2x/(5 - x)

The height of the air ballon at 'm' minutes is expressed in the function and the value of h(3)=1600, h(9)=2800,h(11)=3200

We have given a function h in terms of m. Now we have to explain the contextual meaning of each and every expression it contains

1.) h = It is height at which ballon is cruising above from the ground level.

2.) m = It denotes the instance of minute at which we are talking about

3.) h(m) = The height as the function of minute, means the height of the ballon in changing with respect to the minute

4.) 1000 = It is the height at which ballon was cruising earlier and then started ascending

5.)200 = 200 feet the distance covered in a minute while ascending above

6.) 200m = distance ascended for 'm ' minutes

7.) 1000+200m = The total height that balloon covered after ascending for m minutes.

Now,

height at 3 minute = h(3) = 1000+200(3)=1000+600=1600

height at 9 minute = h(9) = 1000+200(9)=1000+1800=2800

height at x minute = h(x) = 1000+200(x)= 3200

1000 + 200x = 3200

200x = 2200

x = 11

Therefore, h(3) = 1600 , h(9)= 2800,h(11)=3200 are the different values of height 'h' at different 'm' minutes.

The value of cos(A - B) in the simplest form​ will be 0.547.

It is defined as the branch of mathematics that is concerned with the size, shape, and orientation of two-dimensional figures.

It is given that,

tan A = 11/60

tan A = p/b

From Pythagoras therorm

h=√(p²+b²)

h=√(11²+60²)

h=61

Sin A = p/h = 11/60

Cos A = b/h = 60/61

If cos B = 5/13

Sin B = 12/13

cos (A - B) = cos A cos B + sin A sin B

cos (A - B) = (60/61)×(5/13)  + (11/60)×(12/13)

cos (A - B) =0.547

When a number is represented as the sum of its prime factors, this process is known as prime factorization. In prime numbers, there are just two factors: one and the number itself. 2, 3, 5, 7, 11, 13, and other prime numbers are examples of prime numbers. A number is prime factorized when it is represented as a collection of primes.

i) List all prime factors for each number.

Prime Factorization of 6 is:

2 x 3  =  [tex]2^{1}[/tex] x [tex]3^{1}[/tex]

Prime Factorization of 14 is:

2 x 7  =  [tex]2^{1}[/tex]  x[tex]7^{1}[/tex]

Prime Factorization of 15 is:

Find the place in the new list where each prime factor appears as a factor the most frequently before adding it there.

The new superset list is

2, 3, 5, 7

To determine the LCM, multiply these elements collectively.

LCM = 2 x 3 x 5 x 7 = 210

In exponential form:

LCM = [tex]2^{1}[/tex] x [tex]3^{1}[/tex] x [tex]5^{1}[/tex] x[tex]7^{1}[/tex] = 210

LCM = 210

Therefore,

Step-by-step explanation:

The length and the width of the sticky note in millimeters are 2.5 × 10⁻⁵ millimeters and 1.25 × 10⁻³ millimeters respectively.

The dimension of Kendra's sticky note using a meter stick are:

The width of the sticky note is 1.25 × 10⁻⁸ meters and the length of the sticky note is 2.5 × 10⁻⁶ meters.

Now we know,

1 meter = 1000 milimeters.

Therefore, the length of the sticky note in millimeters will be:

L = 2.5 × 10⁻⁸ meters

L = 2.5 × 10⁻⁸ × 1000 millimeters

L = 2.5 × 10⁻⁸ × 10³ millimeters

L = 2.5 × 10⁻⁸ ⁺ ³ millimeters

L = 2.5 × 10⁻⁵ millimeters

So, the width of the sticky note is:

W = 1.25 × 10⁻⁶ meters

W = 1.25 × 10⁻⁶ × 10³ millimeters

W = 1.25 × 10⁻³ millimeters

Hence, the dimension in millimeters is: the width and length of the sticky note is 1.25 × 10⁻³ millimeters and 2.5 × 10⁻⁵ millimeters respectively.

Given:

Charge for 1 day = $100

Charge for each additional day = $50

Let's assume

The cost of rent is y.

The number of days is x.

The total cost, y according to the data provided can be calculated by the equation,

y = 100 + 50x

Using y = mx+c, when graphing a step function that represents the relationship between the number of days and the total cost,

The gradient or slope will be always 50 for the graph.

So, when x = 0, y = 100 + 0 = 100

When x = 1, y = 100 + 50 = 150

When x = 2, y = 100 + 50 × 2 = 200

When x = 3, y = 100 + 50 × 3 = 250

Thus the step function is,

Euclidean geometry is the study of flat and solid figures based on the axioms and theorems of the Greek mathematician Euclid (c. 300 BCE). Euclidean geometry is the plane and solid geometry that is usually taught in High schools.

Euclidean features are ideally suited to defining man-made settings (which are usually in 3D) and are reasonably simple for the user to give.

The incorporation of scene restrictions into the model acquisition process decreases the number of unique configurations for calibration and enables model reconstruction using small sets or even single photos despite the presence of multiple occlusions.

Another obvious use for such a technology is augmented reality. After rebuilding, real-world scene models can be merged with other reconstructed or synthetic models. This is particularly beneficial in architectural applications.

Indeed, before an architectural project is approved, its influence on the existing environment is represented using hand-drawn or computer-aided design (CAD) city models.

The process of creating such models is time-consuming and needs more previous knowledge than scene reconstruction from photos.

Furthermore, when necessary, classic architectural resources such as maps and architectural drawings are simple to include in an interactive reconstruction method.
