Solve and state the correct answer for the trigonometric equation below
tan y = 6 - 4 cot y where
[tex] 0 \leqslant y \leqslant 360[/tex]
Answer:
y = {37.4°, 79.2°, 217.4°, 259.2°}Step-by-step explanation:
Given
tan y = 6 - 4 cot yWe now that
cot y = 1/tan ySubstitute tan y with x:
x = 6 - 4/xx² = 6x - 4x² - 6x + 4 = 0x² - 6x + 9 = 5(x - 3)² = 5x - 3 = ± √5x = 3 + √5x = 3 - √5Replace x with tan y:
tan y = 3 + √5 ⇒ y = arctan (3 + √5) ≈ 79.2° + 180°ktan y = 3 - √5 ⇒ y = arctan (3 - √5) ≈ 37.4° + 180°kAnswer is:
y = {37.4°, 79.2°, 217.4°, 259.2°} PLEASE ANSWER THIS QUESTION RIGHT The Jimenez family is bringing 12 packages of hamburger and hotdog buns to the neighborhood

Step-by-step explanation:
took the test egde 2021
The difference between the new, colder temperature and the original temperature is 30 ° C.
What is temperature ?"Temperature, measure of hotness or coldness expressed in terms of any of several arbitrary scales and indicating the direction in which heat energy will spontaneously flow—i.e., from a hotter body (one at a higher temperature) to a colder body (one at a lower temperature). Temperature is not the equivalent of the energy of a thermodynamic system; e.g., a burning match is at a much higher temperature than an iceberg, but the total heat energy contained in an iceberg is much greater than the energy contained in a match. Temperature, similar to pressure or density, is called an intensive property—one that is independent of the quantity of matter being considered—as distinguished from extensive properties, such as mass or volume."
Given,
The old temperature is = 18°C
The new temperature is = -12°C
The difference in temperature is [tex](-12\°C - 18\°C) = 30\°C[/tex]
Hence, A is the correct option.

A boat’s velocity, measured in meters per second, is described by vector = 〈 -3, 4 〉. In two or more complete sentences explain how to find the speed of the boat and the direction it is traveling in standard position. In your final answer, include all of your calculations.
Velocity is a vector, so it has a magnitude and direction.
Speed is its magnitude, which is obtained from
|〈-3, 4〉 m/s| = √((-3 m/s)² + (4 m/s)²) = √(25 m²/s²) = 5 m/s
Its direction is an angle θ made with the positive horizontal axis, satisfying
tan(θ) = (4 m/s) / (-3 m/s) = -4/3 → θ = arctan(-4/3) + 180°n
where n is any integer. Now you have to consider that the x coordinate is negative and the y coordinate is positive, so 〈-3, 4〉 points into the second quadrant, and we get an angle there for n = 1 of about
θ ≈ 126.87°
Alternatively, you can use the vector 〈1, 0〉 in place of the axis, then compute the angle by relating it to the dot product, so θ is such that
〈-3, 4〉 • 〈1, 0〉 = |〈-3, 4〉| |〈1, 0〉| cos(θ)
(-3)•1 + 4•0 = √((-3)² + 4²) • √(1² + 0²) cos(θ)
-3/5 = cos(θ) → θ = arccos(-3/5) + 360°n
where again, n is any integer, and we get the same solution θ ≈ 126.87° in the second quadrant when n = 0.

Sara can type 90 words in 4 minutes. About how
many words would you expect her to type in 10
minutes at this rate?
Group of answer choices
Answer:
225 words
Step-by-step explanation:
In order to find the answer to this question we have to find how many words she writes in 1 minute. To do this you need to divide 90 words by 4 minutes:
(90)/4 = 22.5 words/minute
Now that the words per minute is found, we can multiply it by the 10 minutes to find how many words she can write in 10 minutes:
(22.5)(10) = 225
Therefore, Sara can type about 225 words in 10 minutes.
I hope this helps!!

220 miles ÷ 8 hours
We want a unit rate where
1 is in the denominator,
so we divide top and bottom by 8
220 miles ÷ 8
8 hours ÷ 8
=

Suppose 30% of the people in your town talk on their cell phones and drive at the same time. If you stood on a busy street corner and watched 50 people drive by, what is the standard deviation of the model you would use for the sample proportion you observe?
Answer:
[tex]SD= 3.24[/tex]
Step-by-step explanation:
Given
[tex]Proportion, p = 30\%[/tex]
[tex]Population, n = 50[/tex]
Required
Determine the standard deviation
Standard Deviation (SD) is calculated as:
[tex]SD= \sqrt{np(1-p)}[/tex]
Substitute values for n and p
[tex]SD= \sqrt{50 * 30\% * (1-30\%)}[/tex]
Convert percentage to decimals
[tex]SD= \sqrt{50 * 0.30 * (1-0.30)}[/tex]
[tex]SD= \sqrt{50 * 0.30 * 0.70}[/tex]
[tex]SD= \sqrt{10.5}[/tex]

Car rideshare services are a popular option for people needing to move about in large cities. The scatterplot shows the distances of trips and fares, in dollars, for an adult living in a city over a period of a month. The value of r for the scatterplot is 0.950.
How would the value of the correlation coefficient change if the fares were plotted on the x-axis and distances on the y-axis?
The value of the correlation coefficient would be –0.950.
The value of the correlation coefficient would not change.
The value of the correlation coefficient would be closer to 0.
The value of the correlation coefficient would be closer to 1.
Answer:
The value of the correlation coefficient would not change.
Step-by-step explanation:
If the relationship between distance of trips and fares in dollars gives a correlation coefficient value of 0.950. This can be interpreted to mean that the relationship between both variables is strong and positive such that an increase in distance leads to corresponding increase in fares of the trip and vice versa. Thus, interchanging the axis upon which the variables are plotted would still tied the same correlation Coefficient value as the correlation coefficient does not depend on the axis upon which the variables are plotted.
Step-by-step explanation:
If its change it will not be right

Parent function f(x)= -4x^2Transformed function g(x) = (x+3)^2 + 2/3We need to describe the transformations from f to g
The transformation steps are:
f(x) = -4x^2 → 4x^2 → x^2 → (x+3)^2 → (x+3)^2 + 2/3 = g(x)So there are four transformations:

The sales tax in a certain county is 7%. If an item marked at $19.94 is sold within the county, estimate the final cost of the item once tax is included.
Given:
Rate of sales tax = 7%
Marked price of an item = $19.94
To find:
The final cost of the item once tax is included.
Solution:
We have,
Rate of sales tax = 7%
Marked price of an item = $19.94
[tex]\text{Sales tax}=\dfrac{7}{100}\times 19.94[/tex]
[tex]\text{Sales tax}=1.3958[/tex]
Now, final cost of the item once tax is included is
[tex]\text{Final cost}=\text{Marked price}+\text{Sales tax}[/tex]
[tex]\text{Final cost}=19.94+1.3958[/tex]
[tex]\text{Final cost}=21.3358[/tex]
Therefore, the final cost of the item once tax is included is $21.3358.
Morgan is making a square quilt with an area of 49 square feet for her nephew. The quilt is made out of square pieces that have a perimeter of 24 square inches. How many patches of material will Morgan need to complete the quilt for her nephew?
Answer:
196 patches
Step-by-step explanation:
We are told that the quilt is made out of square pieces that have a perimeter of 24 square inches.
This means that, length of one side = 24/4 = 6 inches.
Now since Morgan is making a square quilt with an area of 49 square feet for her nephew, let's convert 6 inches to ft.
6 inches = 6 × 1/12 = 0.5 ft
Thus, the area of a small quilt = 0.5 × 0.5 = 0.25 ft²
Number of patches = 49/0.25 = 196 patches
Each large roll of ribbon has 20yards. Each package takes 3 feet of ribbon. How many packages can be wrapped
Answer:
20
Step-by-step explanation:
20*3/3 = 20
The number of yards in 1 foot is 3 thus 20 packages can be wrapped.
What is unit conversion?To convert any unit into another is called a unit conversion.
In order to convert units, we need to care about their dimensions their dimension should not be changed.
As per the given,
Length of ribbon = 20 yards
Each package required = 3 feet
Since 1 yard = 3 feet so,
Each package required = 1 yard
The number of packages that can be wrapped = 20/1 = 20
Hence" The number of yards in 1 foot is 3 thus 20 packages can be wrapped".
