A) To find the domain and range of a function, we need to examine the set of all possible input values (domain) and the set of all possible output values (range).

For the given function f = {(1, 2), (−1, 2), (2, 1), (2, −1)}, the domain is the set of all x-values in the ordered pairs, which in this case is {1, -1, 2}. Therefore, the domain of f is {1, -1, 2}. Similarly, the range is the set of all y-values in the ordered pairs. Looking at the given function, we have y-values of 2, 1, and -1. Hence, the range of f is {2, 1, -1}.

B) To find f(-1), we need to determine the value of the function when the input is -1. From the given function f = {(1, 2), (−1, 2), (2, 1), (2, −1)}, we can see that f(-1) = 2. Therefore, f(-1) is equal to 2.

C) To find the value of x such that f(x) = -1, we need to determine the input value (x) that gives an output of -1. From the given function f = {(1, 2), (−1, 2), (2, 1), (2, −1)}, we can see that there is no ordered pair where the y-value is -1. Therefore, there is no value of x for which f(x) is equal to -1.In summary, the domain of f is {1, -1, 2}, the range is {2, 1, -1}, f(-1) = 2, and there is no value of x such that f(x) = -1.

By graphing the equation x^2 + 5x + 3 = 0, we can determine the approximate solutions to be -4.3 and -0.7, rounded to the nearest tenth. Therefore, the correct answer is option b, -4.3, -0.7.

To solve the equation x^2 + 5x + 3 = 0 by graphing, we plot the graph of the quadratic function y = x^2 + 5x + 3 and find the x-values where the graph intersects the x-axis.

When we graph the quadratic function, we observe that it intersects the x-axis at two distinct points. By examining the graph, we can estimate the approximate x-values of these points.

Rounding to the nearest tenth, we find that the solutions are approximately -4.3 and -0.7. Comparing these values to the options provided, we see that option b, -4.3, -0.7, is the closest match.

Therefore, by graphing the equation x^2 + 5x + 3 = 0, we determine that the approximate solutions are -4.3 and -0.7, rounded to the nearest tenth, leading us to choose option b as the correct answer.

The minimum score needed to receive a grade of A is approximately 86.06.

To find the minimum score needed to receive a grade of A, we need to determine the cutoff point that corresponds to the top 12.3 percent of students in a normal distribution with a mean of 65 and a standard deviation of 18.

First, we need to find the z-score associated with the top 12.3 percent.

The z-score represents the number of standard deviations a data point is from the mean.

Using a standard normal distribution table or a calculator, we can find the z-score that corresponds to the top 12.3 percent.

The z-score is approximately 1.17.

Next, we can use the formula for z-score conversion to find the corresponding score value:

z = (x - μ) / σ

Rearranging the formula to solve for x (the score):

x = z * σ + μ

Plugging in the values:

x = 1.17 * 18 + 65

x ≈ 86.06

Therefore, the minimum score needed to receive a grade of A is approximately 86.06.

3. 19 prizes

Step-by-step explanation:

The given conditions for winning a prize are as follows;

The prize that every 5th customer gets = A free bagel

The prize that every 9th customer gets = A free blueberry muffin

The prize that every 12th customer gets = A free slice of carrot cake

Therefore, the prizes will go to the 5th, 9th, 10th, 12th, 15th, 18th, 20th, 24th, 25th, 27th, 30th, 35th, 36th, 40th, 45th, 48th, and 50th positon customers

1. Diego being 23rd is right for thinking that he should get farther back in line in order to get a prize

He should get one position behind to 24th position

The reason is because prizes will be given to every 12th customer, and the 24th customer is the second 12th customer

2. Yes Jada will get a price as her position corresponds to the consecutive 9th and 12th customers position

Jada will get a free blueberry muffin and a free slice of carrot cake

b. It is possible for Jada to get more than one prize

This is so because her position coincides with the consecutive 9th and 12th customers position

3. The number prizes that Lin's uncle gives away are;

roots are real and rational

Step-by-step explanation:

given a quadratic equation in standard form

ax² + bx + c = 0 ( a ≠ 0 ) , then the discriminant is

b² - 4ac

the discriminant informs on the nature of the roots

• if b² - 4ac > 0 then roots are real and irrational

• if b² - 4ac > 0 and a perfect square, then roots are real and rational

• if b² - 4ac = 0 , then roots are real and equal

• if b² - 4ac < 0 , then the roots are not real

for 2x² + 7x + 6 = 0 , in standard form

with a= 2, b = 7 , c = 6 , then

b² - 4ac = 7² - (4 × 2 × 6) = 49 - 48 = 1

Thus,  the average cost per unit for an output of q units is given by the equation c/q = 12000/q + 7, where the fixed cost is $12,000 and the variable cost is given by the function cv = 7q.

The given equation for the total cost of producing q units of a product is c = 5000 + 6q.

To find the average cost per unit for an output of q units, we need to divide the total cost by the number of units produced.

Thus, the average cost per unit can be written as c/q.

Substituting the given equation for c in terms of q, we get

c/q = (5000 + 6q)/q.

Simplifying this expression, we get c/q = 5000/q + 6.

Now, we are given that the fixed cost is $12,000 and the variable cost is given by the function cv = 7q.

The total cost equation c can be written as the sum of the fixed cost and the variable cost, i.e., c = 12000 + cv. Substituting the given equation for cv, we get c = 12000 + 7q.

Substituting this equation for c in terms of q in the expression we derived earlier for c/q, we get c/q = (12000 + 7q)/q. Simplifying this expression, we get c/q = 12000/q + 7.

Therefore, the average cost per unit for an output of q units is given by the equation c/q = 12000/q + 7, where the fixed cost is $12,000 and the variable cost is given by the function cv = 7q.

Step-by-step explanation:

From the given function f(x) the value of expression f(f(81)) is equal to 3.

Let's see how to find the answer to the question:

Find (f0f)(81)

In the given question, we need to find the value of (f0f)(81). This notation means (f◦f)(81).

Given that f(x)= sqrt(x) and g(x) =\((x - 7)^2\).

We know that to find (f◦f)(x), we need to evaluate f(f(x)).

This means we need to first evaluate f(x), and then evaluate f(f(x)).

To find (f◦f)(81), we need to find f(f(81)).

Using the function f(x), we find f(81):

f(81) = sqrt(81) = 9

Now, we use the function f(x) again to find f(f(81)):

f(f(81)) = f(9)

= sqrt(9)

= 3

Thus, we have found that

(f◦f)(81) = f(f(81))

= 3

Hence, the value of (f0f)(81) is 3.

Therefore, the value of (f0f)(81) is 3.

Answer: So, the coterminal angle of 450° is -90°.

Step-by-step explanation:(i) 395°  

Write 395° in terms of 360°.

395°  =  360° + 35°

So, the coterminal angle of 395° is 35◦

(ii) 525°

Write 525° in terms of 360°.

525°  =  360° + 165°  

So, the coterminal angle of 525° is 165°.

(iii) 1150°

Write 1150° in terms of 360°.

1150°  =  3(360°) + 70°  

So, the coterminal angle of 1150° is 70°.

(iv) -270°

Write -270° in terms of 360°.

-270°  =  -360° + 90°

So, the coterminal angle of 270° is 90°.

(v) -450°

Write -450° in terms of 360°.

-450°  =  -360° - 90°  

So, the coterminal angle of 450° is -90°.

The actual parameter (argument) to assign to each formal parameter is the order of the parameters indicates how they are assigned (option b).

The answer choice that determines which actual parameter (argument) to assign to each formal parameter depends on the programming language and the function definition.

Answer choice (b) is generally correct: the order of the parameters indicates how they are assigned. In many programming languages, the parameters are assigned in the order they appear in the function definition. When calling the function, you pass the actual arguments in the corresponding order.

Answer choice (a) is not always true. While some programming languages require the names of the formal parameters to match the names of the actual arguments, others may allow different names as long as the order is maintained.

Answer choice (c) is incorrect. Functions can accept multiple parameters, not just one.

Answer choice (d) is also incorrect. In most programming languages, you don't need to manually assign each parameter at the beginning of the function. The assignment is handled automatically when the function is called with the appropriate arguments.

So, the most accurate answer is (b) - the order of the parameters indicates how they are assigned.

Cohen's conventions for interpreting d, this effect is small. Therefore, the correct answer is a. small.

According to Cohen's conventions for interpreting the effect size (d), the effect described in the study is considered "small." Cohen's conventions provide a general guideline for categorizing the magnitude of an effect size.

In this case, the effect size (d) is calculated to be 0.02. Cohen's conventions typically classify effect sizes as follows:

Small effect: d = 0.2

Medium effect: d = 0.5

Large effect: d = 0.8

Since the effect size of 0.02 is significantly smaller than the threshold for a small effect (0.2), it falls into the "small" category. This means that the difference in the number of words uttered per day between men and women, as reported in the study, is relatively small or negligible in practical terms.

Therefore, the correct answer is a. small.

The solution to the given initial-value problem is  x(t) = c1(e-ωt - eωt) = 2c1 sin ωt

The given initial-value problem is a second-order differential equation: d2x dt2 + ω2x = f0 sin ωt, x(0) = 0, x '(0) = 0

First, we can solve the homogeneous equation d2x dt2 + ω2x = 0 using the method of characteristic equation. The characteristic equation is r2 + ω2 = 0, which has two solutions r1 = -ω, r2 = ω.

The general solution to the homogeneous equation can be expressed as:

x(t) = c1e-ωt + c2eωt

Next, we can solve the non-homogeneous equation d2x dt2 + ω2x = f0 sin ωt. Since the right-hand side of the non-homogeneous equation has a sinusoidal form, we can use the method of variation of parameters to solve it.

The particular solution can be expressed as:

x(t) = A sin ωt + B cos ωt

By substituting the initial conditions, we can get:

A = 0, B = 0

Therefore, the solution to the given initial-value problem is:

x(t) = c1e-ωt + c2eωt

The constant c1 and c2 can be determined by the initial conditions:

x(0) = c1 + c2 = 0

x'(0) = -ωc1 + ωc2 = 0

Therefore, c1 = -c2 and c1 + c2 = 0.

Hence, the solution to the given initial-value problem is:

x(t) = c1(e-ωt - eωt) = 2c1 sin ωt
