Sin corresponds to the y-value, so sin would be positive at Quadrants 1 and 2.
Tan, which is y/x (sin/cos), is positive at Quadrants 1 and 3.
So at quadrant 1 is where both sin and tan are positive.

The length of a rectangle is 2 yd longer than its width. if the perimeter of the rectangle is 24 yd , find its area.
Answers
Length = x +2
Perimeter = 24
Area = Width • Length = ?
Perimeter = 24 = 2(x +2) + 2(x)
= 2x + 4 + 2x
= 4x + 4
= 20 = 4x
= 5 = x
Width = x = 5, therefore Length = (5) + 2 = 7
Area = Width • Length = 5 • 7 = 35
Area = 35 yards
How many corners does a cube have? how many faces does a cube have? how many other cubes would share a given corner atom or face atom if several cubes were stacked side-to-side, front-to-back, and top-to-bottom?
Answers
A cube is a 3-dimensional solid figure made by square faces. It would have 8 corners which connects the faces of the cube.
how many faces does a cube have?
There would be 6 faces in a cube
how many other cubes would share a given corner atom or face atom if several cubes were stacked side-to-side, front-to-back, and top-to-bottom?
If several of these cubes are being stacked side-to-side, front-to-back, and top-to-bottom, each corner would share a total of eight cubes. All of the corners would share a different cube. We have eight corners thus eight cubes.
What is a rule that describes the translation ABCD ⇒A' B' C' D'?

A. IS WRONG
Answers
* step 1) move 3 units to the left

The movement in step 2 means y becomes y+2
Put this together and (x,y) turns into (x-3, y+2)
That's the same as writing T<-3, 2> as choice D is saying
Answer: Choice D
Final answer:
The question seeks the correct translation rule for the movement of quadrilateral ABCD to A'B'C'D'. Translation in geometry involves moving a shape in a consistent direction and distance. Given option A is incorrect, and considering directionality, T <-3,2> (ABCD) is another possibility for the translation.
Explanation:
The question asks for the rule that describes the translation of quadrilateral ABCD to A'B'C'D'. A translation in geometry is a type of transformation that moves every point of a shape the same distance in the same direction. Since option A, which is T <3,-2> (ABCD), is given as incorrect, let's analyze the remaining options.
To determine the correct rule for translation, we need to look at the relative position of the original points and their corresponding points after the translation. For example, if point A were at (x,y) and A' is at (x+3, y-2), this would correspond to a translation of 3 units to the right and 2 units down, which is described by the vector <3, -2>.
Since option A is incorrect and we know that the transformation corresponds to a translation and not a reflection or rotation, let's consider the other options. Looking at option D, T <-3,2> (ABCD), this would imply that every point of quadrilateral ABCD is moved 3 units to the left (because of -3) and 2 units up (because of 2), which would be the reverse of what is described in option A.

The students in the fourth grade sold 684 erasers for a fund-raiser. They sold 4 times as many erasers as the students in fifth grade. How many erasers did the students in 5 grade sell?
Answers
so
684 / 4 = 171
answer
students in 5 grade sold 171 erasers
The students in fifth grade sold 171 erasers
How Many Erasers Did the Fifth Grade Students Sell?
The question asks us to find out how many erasers the students in fifth grade sold based on the sales of fourth graders. We are told that the fourth grade students sold 684 erasers and that this number is 4 times the amount sold by the fifth graders. To find the number of erasers sold by the fifth graders, we need to perform a division operation.
Setting up the equation, let x be the number of erasers the fifth-grade students sold. Thus, 4x = 684. To solve for x, we divide both sides of the equation by 4. Therefore, x = 684 / 4 = 171.
So, the students in fifth grade sold 171 erasers for the fund-raiser.
how much would $140 invested at 6% interest compounded monthly be worth after 15 years? round your answer to the nearest cent
Answers
The principle amount of $140 invested at a 6% rate of interest compounded monthly be worth after 15 years will be $340.
What is compound interest?Compound interests are those interests where the principle amount always going to change.
For example, if you give $100 to anyone with 5% interest monthly then at the end of your month your value becomes $105 and this will become the principal amount.
Given that the principal amount is $140
P = $140
The rate of interest is 6%
r = 6%
Number of time period 15 years
t = 15
Now by compounding interest formula
A = [tex][1+r/100]^{t}[/tex]
By putting all value we get
A = [tex][1 + 6/100]^{15}[/tex]
A = $340 hence, $340 will be the total amount after 15 years.

What are the amplitude, period, and midline of f(x) = 3 cos(4x − π) + 2?
Answers
Answer:
The amplitude of the function is 3, period of the function is [tex]\frac{\pi}{2}[/tex] and midline of the function is 2.
Step-by-step explanation:
The given function is
[tex]f(x)=3\cos(4x-\pi)+2[/tex] .... (1)
The standard form of a Cosine function is
[tex]g(x)=a\cos(bx+c)+d[/tex] ... (2)
where, a is amplitude, period is [tex]\frac{2\pi}{b}[/tex] and d is midline.
From (1) and (2), we get
[tex]a=3,b=4,d=2[/tex]
The amplitude of the function is
[tex]a=3[/tex]
The period of the function is
[tex]\frac{2\pi}{b}=\frac{2\pi}{4}=\frac{\pi}{2}[/tex]
The midline of the function is
[tex]d=2[/tex]
Therefore the amplitude of the function is 3, period of the function is [tex]\frac{\pi}{2}[/tex] and midline of the function is 2.

y + 1 = -3x + 15
y = -3x + 15 - 1
y = -3x + 14 <== or f(x) = -3x + 14
Y+1= -3(x+5) in order to solve first write down the function, then find the current of the function.
Y+1=-3x-15 then this is the current of the function. Multiply the -3 times the X and the 5.
Y=-3x-14 finally this is the slope. To get the slope I added the 1 to the -15

The area (A) of a circle with a radius of r is given by the formula A=pier^2 and its diameter (d) is given by d=2r. Arrange the equations in the correct sequence to rewrite the formula for diameter in terms of the area of the circle.
Answers
Final answer:
The diameter d of a circle can be expressed in terms of the area A by first solving the area formula A = πr^2 for r, giving r = √(A/π), and then substituting r into the diameter formula d = 2r, resulting in d = 2√(A/π).
Explanation:
To rewrite the formula for the diameter of a circle in terms of the area, we start with the given formula for area A = πr^2 and the equation for diameter d = 2r. Our aim is to express the diameter d solely in terms of the area A. To achieve this, we rearrange the area formula to solve for the radius r:
A = πr^2r^2 = A/πr = √(A/π)Then, we substitute r into the diameter formula:
d = 2rd = 2√(A/π)Thus, the diameter d can be expressed in terms of the area A as d = 2√(A/π).

[tex]\bf V(x)=75x-\cfrac{1}{4}x^3\implies \cfrac{dV}{dx}=75-\cfrac{3}{4}x^2\implies 0=75-\cfrac{3}{4}x^2 \\\\\\ \cfrac{3}{4}x^2=75\implies 3x^2=300\implies x^2=\cfrac{300}{3}\implies x^2=100 \\\\\\ x=\pm10\impliedby \textit{is a length unit, so we can dismiss -10}\qquad \boxed{x=10}[/tex]

Jennifer is on a trip and travels a distance of 150 miles. she spends some of her time walking, and some of her time travelling by train. if she spends w hours walking and t hours travelling by train, what is the meaning of 3w in the equation below? 50t + 3w =150
Answers
In the equation 50t + 3w = 150, 3w represents the distance Jennifer travels by walking in 3 hours.
Explanation:In the equation 50t + 3w = 150, the term 3w represents the distance Jennifer travels by walking. Since w represents the number of hours she spends walking, 3w represents the distance she walks in 3 hours. This is because the rate of walking is constant, so if Jennifer walks for 1 hour and covers a certain distance, she would walk 3 times that distance in 3 hours.
