If θ is an angle in standard position and its terminal side passes through the point (-9,5), find the exact value of sec ⁡ θ secθ in simplest radical form.

The value of the car in 2000 is expected to be $3800, given a starting value of $7700 in 1990 and a decrease of $390 per year for 10 years.

To find the value of the car in each subsequent year, we can subtract $390 from the previous year's value. Let's calculate the value of the car for each year from 1990 to 2000.

Year 1990: $7700

Year 1991: $7700 - $390 = $7310

Year 1992: $7310 - $390 = $6920

Year 1993: $6920 - $390 = $6530

Year 1994: $6530 - $390 = $6140

Year 1995: $6140 - $390 = $5750

Year 1996: $5750 - $390 = $5360

Year 1997: $5360 - $390 = $4970

Year 1998: $4970 - $390 = $4580

Year 1999: $4580 - $390 = $4190

Year 2000: $4190 - $390 = $3800

Therefore, the value of the car is expected to be $3800 in the year 2000.

Answer:

\(y=2x+5\)

Step-by-step explanation:

i did the math

All the bottles of water will be gone on the 10th day since Jazzy started with 10 bottles and consumes one bottle per day (represented by the negative slope of the line).

The equation y = -x + 10 represents the number of bottles of water Jazzy has left after x days, assuming she starts with 10 bottles.

When x = 0, the equation becomes y = -0 + 10, which means Jazzy has 10 bottles on the first day.

When y = 0, the equation becomes 0 = -x + 10, which means Jazzy will run out of bottles on the 10th day.

Therefore, all the bottles of water will be gone on the 10th day since Jazzy started with 10 bottles and consumes one bottle per day (represented by the negative slope of the line).

Answer:fixed ratio

Step-by-step explanation: :)

This is an illustration of a fixed ratio reinforcement schedule: after a predetermined number of responses, Frances is given a reward (in this case, $1). (every pound of worms).

An example of a reinforcement plan utilized in the behavioral psychology concept of operant conditioning is a fixed ratio reinforcement schedule. A reward or reinforcement is delivered according to this schedule after a predetermined number of actions or responses. As an illustration, a rat might receive a food pellet after every 10 lever presses.

Fixed ratio schedules work well for encouraging high response rates since the subject is driven to keep up the activity in order to earn the reward. Yet, if the reinforcement is stopped, the behavior can become less frequent or cease entirely.

Fixed ratio schedules can also cause behaviors to become rigid or stereotyped because the subject may start concentrating only on the number of responses required to earn the reward and stop considering other options or actions.

Overall, fixed ratio reinforcement regimens can be helpful in teaching both humans and animals to carry out particular tasks, but they should be utilized with caution and consideration for any unexpected consequences.

Answer:

Option D [\(y=6.61\,*\,1.55^x\)] in the list of possible answers

Step-by-step explanation:

For this problem you are supposed to use a calculator that allows you to do an exponential regression. There are many tools that can help you with that, depending on what your instructors has assigned for your class.

I am showing you the results of a graphing tool I use, and which after entering the x-values and the y-values in independent "List" forms, when I request the exponential regression to fit the data, I get what you can see in the attached image.

Notice that the exponential of best fit with my calculator comes in the form:

\(y=A\,e^{k\, x}\)

with optimized parameters:

\(A \approx 6.6114\,\,\,and\,\,\, k=0.4378321\)

Notice as well that since:

\(e^{0.4378321} \approx 1.5490\)

the exponential best fit can also be written:

\(y=6.611403\,\,*\,e^{0.4378321\, x}=6.611403\,*\,1.549^{\,x}\)

and this expression is very close to the last option shown in your list of possible answers

Answer:

D is your answer

Step-by-step explanation:

(2y-7) (y+6) that is my answer and it matches with D promise 100%

The possible dimensions of the pool are the factors of the trinomial, which are:

2y - 7 and y + 6

The correct answer is (D).

An expression contains one or more terms with addition, subtraction, multiplication, and division.

We always combine the like terms in an expression when we simplify.

We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.

Example:

1 + 3x + 4y = 7 is an expression.

3 + 4 is an expression.

2 x 4 + 6 x 7 – 9 is an expression.

33 + 77 – 88 is an expression.

We have,

To find the possible dimensions of the pool, we need to factor the trinomial 2y² + 5y - 42.

We can start by looking for two numbers that multiply to -84 (the product of the first and last coefficients of the trinomial) and add up to 5 (the middle coefficient of the trinomial).

Those numbers are 12 and -7, because 12 x -7 = -84 and 12 + (-7) = 5.

Using these numbers, we can rewrite the trinomial as:

2y² + 12y - 7y - 42

Now we can factor by grouping:

(2y² + 12y) - (7y + 42)

2y(y + 6) - 7(y + 6)

(2y - 7)(y + 6)

So the possible dimensions of the pool are the factors of the trinomial, which are:

2y - 7 and y + 6

Therefore,

The possible dimensions of the pool are the factors of the trinomial, which are:

2y - 7 and y + 6

The correct answer is (D) 2y - 7 and y + 6.

Answer:

D = p +(.094×p)

Step-by-step explanation:

1. Take 9.4% and make it a decimal. 9.4%=0.094

2. Multiply 0.094 by the original price of the item (seen above as the variable p).

3. Next find the sum of the original price and the number from step 2.

Plugging in some example numbers, we can see this in the expression. Let's leave D as an unknown but make the original price $24. The product of 24 and 0.094 is 2.256. We add this new number to 24 and get 26.256. That's our answer! If the sales tax on a $24 item is 9.4%, the item costs $26.256 after tax is added to the purchase.

You want a graph of P = 125 +50W.

The given equation is in slope-intercept form. The independent variable is W, and the dependent variable is P.

Usually, the independent variable is graphed on the horizontal axis, which you have done.

The dependent variable is graphed on the vertical axis, which you have done.

The axes are correctly labeled and graduated.

The "y-intercept" (P value) when the independent variable is zero is the constant in the equation, 125. You have correctly shown that on the graph.

The slope of the line is the coefficient of the independent variable (W) in the equation. You have correctly shown that P increases by 50 when W increases by 1.

Yes, you properly graphed the equation.

An equation is a mathematical statement that is made up of two expressions connected by an equal sign.

Example:

2x + 3 is an equation.

2x + 4 = 5 is an equation.

We have,

S = (1/2)at² + \(v_{0}\)t + \(s_{0}\)

We will solve for a = acceleration.

Subtract \(v_{0}t ~and~s_{0}\) on both sides.

S - \(v_{0} ~-~s_{0}\) = (1/2)at²

Multiply 2 on both sides.

2 (S - \(v_{0} ~-~s_{0}\)) = at²

Divide both sides by t².

2(S - \(v_{0} ~-~s_{0}\)) / t² = a

a = 2(S - \(v_{0} ~-~s_{0}\)) / t²

a = 2 (S - \(v_{0} ~-~s_{0}\)) / t²

Answer:

Step-by-step explanation:

vertical line is parallel to y-axis so its equation is always  x = x₀

at any given point we have coordinates: (x₀, y₀)

given point (-4, 7) means  x₀ = -4

so the equation of a vertical line passing through the point (-4, 7) is x=-4

Functions are special relaionships that connect an element of one set of numbers, with one element in another set of numbers.

The most comon way to represent functions is connecting elements of a set of Real numbers called the "Domain", to another number in a set called the Range (and whose elements are identified with the letter "y")

Using math operations one can relate x values with y values via an equation of the type:

y = 2 x - 5

where you have a mathematical form of that relationship, that allows you to know given the value of one member (x) of the Domain what number is associated with it in the Range.

For example, try the number x = 0

and see which y number connects with it:

y = 2 (0) - 5 = 0 - 5 = -5

Then you say that the number 0 in the Domain connects with the number -5 in the Range.

This relationship can also be given with coordinate pairs of the form:

(x, y) mentioning in the first position (where the x is), the number in the Domain that connects to the "y" number of the Range). The y goes in the second place. so for example in the relationship we found above, x = 0 connects with y=-5, you would have a shortcut way to write it as the pair: (0, -5) that tells you which x connects with which y.

The functions can also be given in graph form by plotting the relationship between members of the Domain and the Range on the plane. Graphing a point in the plane location that corresponds to the connected x and y values (like you do in the game "battlefield" when you locate ships on the board.

I know this is very general, but hopefully you got the idea ofa function as a special relationship between numbers, and that they can be expressed in different fashions.

To model the data using an exponential function, you need to find the equation of the function that fits the given data. One way to do this is to use the exponential regression feature of a graphing calculator or statistical software.

Here are the general steps to perform exponential regression:

1. Enter the data into a list on your calculator or software.

2. Plot the data on a scatterplot.

3. Choose "exponential regression" or "exponential model" from the list of regression options.

4. The regression output should give you the equation of the exponential function that best fits the data. The equation will be in the form of y = ab^x, where a is the initial value, b is the growth factor or base, and x is the independent variable (usually time).

Once you have the equation of the exponential function, you can use it to make predictions about the sea turtle population in future years or to estimate the population in past years. However, it's important to note that exponential models are based on assumptions about constant growth rates, which may not always hold true in real-world situations.
