There is no exact measure of θ that satisfies the condition cos(θ) = 3√2 in the first quadrant.

Given that the terminal side of angle θ is in the first quadrant and cos(θ) = 3√2, we can determine the exact measure of θ by using the inverse cosine function, also known as arccosine.

Since cos(θ) = adjacent/hypotenuse, we can set up a right triangle in the first quadrant with the adjacent side as 3√2 and the hypotenuse as 1. The opposite side of the triangle can be found using the Pythagorean theorem.

Let's calculate the length of the opposite side:

opposite^2 + adjacent^2 = hypotenuse^2

opposite^2 + (3√2)^2 = 1^2

opposite^2 + 18 = 1

opposite^2 = 1 - 18

opposite^2 = -17

Since the length of a side cannot be negative, we see that there is no real solution for the length of the opposite side. Therefore, the given cosine value of 3√2 does not correspond to an angle in the first quadrant.

In this experiment, the independent variable is the cost of meals. The researchers are manipulating or varying the cost of meals to observe its effect on the frequency of burping.

The researchers should present the data as a scatter plot or a line graph. This type of graph allows for the visualization of the relationship between the independent variable (cost of meals) and the dependent variable (frequency of burping). The x-axis would represent the cost of meals, and the y-axis would represent the frequency of burping. Each data point would correspond to a specific meal, with the x-coordinate representing the cost and the y-coordinate representing the frequency of burping observed during that meal. By plotting the data points and observing the overall trend, the researchers can analyze whether there is a correlation between the cost of meals and the frequency of burping.

Answer:

I think it's 6 or 0.6

Answer

Check Explanation

Explanation

A) Let the price of one tomato be t

Let the price of one pepper be p

The cost of 12 tomatoes and 7 peppers is $5.36.

12t + 7p = 5.36

The cost of 8 tomatoes and 5 peppers is $3.68.

8t + 5p = 3.68

B) We can then write this together and solve this as a simultaneous equation

12t + 7p = 5.36

8t + 5p = 3.68

Solving simultaneously,

t = 0.26 dollars

p = 0.32 dollars

C) In the context of the question, this means that,

The cost of one tomato = $0.26

The cost of one pepper = $0.32

y=-\frac{2}{5}x+\frac{19}{5}y=−52x+519

Further explanation:

We have to find the equation of the line first to graph the line.

The general form of slope-intercept form of equation of line is:

y=mx+by=mx+b

Given

m=-\frac{2}{5}m=−52

Putting the value of slope in the equation

y=-\frac{2}{5}x+by=−52x+b

To find the value of b, putting the point (-3,5) in equation

\begin{gathered}5=-\frac{2}{5}(-3)+b\\5=\frac{6}{5}+b\\5-\frac{6}{5}+b\\b=\frac{25-6}{5}\\b=\frac{19}{5}\end{gathered}5=−52(−3)+b5=56+b5−56+bb=525−6b=519

Parallel lines are coplanar lines that never intersect.

Parallel Slopes

All parallel lines have the same relationship between their slopes. For 2 lines to be parallel, their slopes must be equal. The question tells us that the slope of the first line is 2. This means that only answer choices B and D are viable.

The slopes of answer choices A and C are perpendicular to the line given.

Testing the Answers

Both B and D could be parallel to the line given; however, we are also told that the line must pass through (-2, 4). To see which answer is correct, we can plug in the x and y-values and solve. If a line passes through a point, then the equation will be true when the values are plugged in.

Let's start with answer B.

Since this statement is not true, we know that y = 2x + 4 does not pass through the point (-2, 4).

Next, we need to test answer choice D.

This is true, so y = 2x + 8 must pass through the point (-2, 4). Since answer choice D has a parallel slope and passes through (-2, 4), it must be the correct answer.

The equation given has no solution. Option A is correct.

Given that,

five-sixths times the quantity x plus 2 end quantity minus three-sixths times x equals two-sixths times the quantity x plus 5 end quantity.

The equation is the relationship between variables and represented as y = ax + b is an example of a polynomial equation.

5/6[x +2] -3/6x = 2/6x +5
5x /6 + 5/3 - x/2 = 1/3x + 5
5x / 6 -x/2 -x/3 = 5 - 5/3

Step-by-step explanation:

I took the same test p.s. you may need to round.

5.1 w = (-3, 2, -5) can be written as a linear combination of u and v,

5.2 The set {u, v} is linearly independent, and

5.3 (u, v) forms a basis for R³.

5.1 To write the vector w = (-3, 2, -5) as a linear combination of u and v, we need to find scalars x and y such that w = xu + yv. By solving the system of equations xu + yv = w, we can find the values of x and y. Substituting the given values,

we get (-3, 2, -5) = x*(1, 2, -1) + y*(6, 4, 2).

Solving this system, we find x = -1 and y = 1.

Therefore, w = (-3, 2, -5) can be written as a linear combination of u and v as w = -u + v.

5.2 To determine if the set {u, v} is linearly independent, we need to check if the only solution to the equation xu + yv = 0 is x = y = 0.

In this case, we need to solve the system of equations x*(1, 2, -1) + y*(6, 4, 2) = (0, 0, 0). By solving this system, we find that x = 0 and y = 0 are the only solution, which means the set {u, v} is linearly independent.

5.3 To check if (u, v) forms a basis for R³, we need to verify if the set {u, v} spans R³ and is linearly independent. Since we have already established that {u, v} is linearly independent, we only need to check if it spans R³. Any vector in R³ can be expressed as a linear combination of u and v, so (u, v) is indeed a basis for R³.

The number of hours taken to cook the turkey is 8.34.

Susan is going to cook a 25 pound, stuffed turkey for Thanksgiving. Susan plans to cook the turkey for 20 minutes per pound. We need to calculate the number of hours it will take to cook the entire turkey.

Let the time taken to cook the complete turkey be denoted by the variable "T". The time taken to cook the entire turkey is the product of the total weight of the turkey and the time taken to cook one pound of the turkey.

T = 25×20

T = 500

So, it will take a total time of 500 minutes to cook the complete turkey. Now we'll convert the time from minutes to hours. To convert from minutes to hours, we will divide by 60.

T = 500/60

T = 8.34

Hence, it will take 8.34 hours to cook the complete turkey.

Multiply both sides of the equation by 15, the least common multiple of 5,15. Since 15 is positive, the inequality direction remains the same.

3(2×5+3)<15b−8

Multiply 2 and 5 to get 10.

3(10+3)<15b−8

Add 10 and 3 to get 13.

3×13<15b−8

Multiply 3 and 13 to get 39.

39<15b−8

Swap sides so that all variable terms are on the left hand side. This changes the sign direction.

15b−8>39

Add 8 to both sides.

15b>39+8

Add 39 and 8 to get 47.

15b>47

Divide both sides by 15. Since 15 is positive, the inequality direction remains the same.

Jelly beans are $1.5/lb and trail mix is $2.063/lb, according to the data.

A heterogeneous mixture would be a trail mix. When the components of a combination are dispersed unevenly across the mixture, the mixture is said to be heterogeneous. As a mixture of nuts, raisins, and other seeds, trail mix cannot have an evenly distributed dispersion of its ingredients.

t = trail mix, j = jelly beans

3t + 8j = 21

5t + 2j = 18

Solving the first for t

2t = 6j - 3

t = (6j - 3)/2

Substituting

5(6j - 3)/2 + 2j = 18

j = 51/34

j = 1.5, Jelly beans cost $1.5/lb

Given the following :

Total planned amount to invest = 10,000 in two funds:

Fund A at rates 4.5% and

Fund B at 5% simple interest

Total Annual Interest should be = 480

What is the smallest amount you can invest in the 5% fund and still meet your objective?

Let ;

Investment in fund A = principal = a at 4.5%(0.045)

Investment in fund B = principal = (10000 - a) at 5%(0.05)

Simple interest = principal * rate * time

a + (10000 - a) = 10000

(a * 0.045) + (10000 - a) * 0.05 = 480

0.045a + 500 - 0.05a = 480

-0.005a = 480 - 500

-0.005a = - 20

a = 20 / 0.005

a = 4000

4000 at 4.5%

Investment in fund B = principal = (10000 - a)

(10,000 - 4000) = 6000
