False, In the exponential decay function ƒ(x) = a • bx, the b is between 0 and 1.

What is exponential decay function?

In mathematics, the term "exponential decay" refers to the process of a constant percentage rate decline in a value over time.

                     It can be written as y=a(1-b)x, where y represents the final amount, a represents the initial amount, b represents the decay factor, and x is the amount of time that has passed.

How do you calculate an exponential function?

The equation f(x) = ax, in which the input variable x appears as an exponent, describes an exponential function. Both the exponential function and the value of x are dependent on the exponential curve.

                               The exponential function, which has the form, is a significant mathematical function. f(x) = ax.

Answer:

x = 6.8

Step-by-step explanation:

7x + 36 = 12x + 2 (alternate interior angles are congruent)

Collect like terms

7x - 12x = -36 + 2

-5x = -34

Divide both sides

-5x/-5 = -34/-5

x = 6.8

The complete question is given below.

Answer:

Step-by-step explanation: old students- 20

New students- 28

Percentage of change= New students - old students/ Old students x 100

                                      = 28-20/20 x 100

                                      = 40%

Step-by-step explanation:

increase = 28 - 20 = 8.

% change = increase ÷ original × 100

= 8 ÷ 20 × 100

= 0.4 × 100

= 40%

∴ percentage change = 40%

Advertising is the practice and techniques employed to bring attention to a product or service. Advertising aims to put a product or service in the spotlight in hopes of drawing it attention from consumers.

Given is that Bobby Flay is deciding how to advertise a new gourmet restaurant that he is opening. An online ad costs $300, and a TV ad costs $700. He has $7,500 to spend on the ads.

We can write the inequality as -

300x + 700y ≤ 7500

where -

{x} - number of online ads posted

{y} - number of TV ads poste

Plot the inequality on the graph. The shaded region represents the possible number of advertisements of each category Bobby can use to advertise.

Answer:

It’s the last one

Step-by-step explanation:

the measure of angle EGF is 2 * 25 = 50 degrees and angle GCF has a measure of  130 degrees.

what is angle ?

In geometry, an angle is the measure of the amount of turn between two intersecting lines or surfaces, measured in degrees (°) or radians. An angle is formed by two rays or line segments that share a common endpoint, called the vertex.

In the given question,

Based on the information given, we can use the fact that the sum of the measures of the exterior angles of a triangle is 360 degrees to solve for the missing angles.

First, we know that the measure of angle EFG is 180 - 50 = 130 degrees (since angles EFG and EFG' are supplementary).

Next, we can use the fact that the sum of the measures of angles EFG and FGE is equal to the measure of angle EGF. We know that angles FEG and FGE are congruent (given in the problem statement), so each must measure (180 - 130)/2 = 25 degrees. Therefore, the measure of angle EGF is 2 * 25 = 50 degrees.

Finally, we can use the fact that angles GCF and EGF are supplementary (since they are  linear pairs with angles FGE and FGC, respectively) to solve for the measure of angle GCF. Therefore, angle GCF has a measure of 180 - 50 = 130 degrees.

Therefore, the number that makes the polynomial a perfect square quadratic is 100.\(g^{2}\).

I believe you meant to ask about "binomial", which is a statistical term used to describe a type of probability distribution.

In probability theory and statistics, the binomial distribution is a discrete probability distribution that describes the number of successes in a fixed number of independent and identical Bernoulli trials, where each trial has only two possible outcomes (success or failure) and the probability of success is constant across all trials.

The binomial distribution is used in many fields, including biology, engineering, and finance, to model the occurrence of events with two possible outcomes, such as the success or failure of a new product launch or the presence or absence of a genetic trait in a population.

To see why, we can use the technique of completing the square.

Starting with g² - 20g, we want to add and subtract a constant term that will allow us to write the expression as a square of a binomial. To do this, we can take half of the coefficient of the linear term (-20g), square it, and add and subtract the result:

\(g^2-20g + (-20/2)^2 - (-20/2)^2\)

Simplifying this expression, we get:

\((g - 10)^2 - 100\)

Tom bought juice for $30. Jp = $30

Tom purchased squash for $42: Ss = $42

Tom's profit is determined by deducting the expense from the revenue. The sum of the price and the number of units distributed is the revenue:

Pumpkin puree revenue: p * gallon price

Lemon squash sales revenue: s * box price

=>  Income = px + sy

The revenue less the expense equals Tom's profit:

Revenue minus costs equals profit.

=>  Profit =  (px + sy - (Jp + Ss))

Inputting the numbers provided yields:

Venn diagrams are charts that are used to visually represent relationships between sets, operations on those relationships, and set relationships. The Venn diagram, which uses circles that are overlapped, intersected, and not intersected to depict the relationship between sets, was created by John Venn. A set diagram or a logic diagram is another name for a Venn diagram, which shows a variety of set operations such the intersection, union, and difference of sets.

Additionally, it can be used to set items. a depiction of each relationship between several sets. Any closed figure, such as a circle or a polygon (square, hexagon, etc.), can be used to represent a Venn diagram. However, each group is typically represented as a circle.

The winning number in a Pick 4 lottery was 1234 two days in a row.

Now,

Since, there is a 1 in 10,000 chance of drawing any particular four-digit number in a single drawing, there is very little chance that the same number will be picked twice in a row in a Pick 4 lottery.

Even less likely, at one in 100,000,000,000, is the same number being selected three times in a row.

Step-by-step explanation:

To differentiate the function f(x) = 1/x^3, we can use the power rule of differentiation. Here's the step-by-step process:

Write the function: f(x) = 1/x^3.

Apply the power rule: For a function of the form f(x) = x^n, the derivative is given by f'(x) = nx^(n-1).

Differentiate the function: In our case, n = -3, so the derivative is:

f'(x) = -3 * x^(-3-1) = -3 * x^(-4) = -3/x^4.

Therefore, the derivative of the function f(x) = 1/x^3 is f'(x) = -3/x^4.

Answer:

x = - \(\frac{3}{4}\) , x = 1

Step-by-step explanation:

4x² = x + 3 ← subtract x + 3 from both sides

4x² - x - 3 = 0 ← in standard form

consider the factors of the product of the coefficient of the x² term and the constant term which sum to give the coefficient of the x- term.

product = 4 × - 3 = - 12 and sum = - 1

the factors are - 4 and + 3

use these factors to split the x- term

4x² - 4x + 3x - 3 = 0 ( factor the first/second and third/fourth terms )

4x(x - 1) + 3(x - 1) = 0 ← factor out (x - 1) from each term

(x - 1)(4x + 3) = 0 ← in factored form

equate each factor to zero and solve for x

4x + 3 = 0 ( subtract 3 from each side )

4x = - 3 ( divide both sides by 4 )

x = - \(\frac{3}{4}\)

x - 1 = 0 ( add 1 to both sides )

x = 1

solutions are x = - \(\frac{3}{4}\) , x = 1
