If the measure of angle is 0 is 7pi/4, which statements are true?
The measure of the reference angle is 45°.
The measure of the reference angle is 30°.
tan(0) = -1
The measure of the reference angle is 60°.
cos(0) = -√2/2
sin(0) = -√2/2
The statement(s) that are true is that the measure of the reference angle is 45°.
What is the conversion of radians to degrees?The conversion of an angle in radian to a degree can be determined by the multiplication of the given angle in radian by 180/π.
From the given information:
[tex]\mathbf{\theta = \dfrac{7 \pi}{4}}[/tex]
To degrees, we have:
[tex]\mathbf{\theta = \dfrac{7 \pi}{4} \times \dfrac{180}{\pi}}[/tex]
[tex]\mathbf{\theta =315^0}[/tex]
A reference angle is an angle that measures the remaining distance (called the terminal distance) to the x-axis.
315° is in the 4th quadrant, i.e.
= 360° - 315°
= 45°
Therefore, the statement(s) that is true is:

The function graphed models the profits, P(c), in thousands of dollars a store earns as a function of the number of clerks, c, working that day.
Which statements are true based on the model?
Select each correct answer.
The store earns about $50,000 in profits on its best days.
Maximum profits are earned when there are 6 clerks working.
The store earns profits when no clerks are working.
Maximum profits are earned when there are 3 clerks working.
The store loses money when 7 or more clerks are working.
Answer:
See below ~
Step-by-step explanation:
The true statements based on the graph :
Maximum profits are earned when there are 3 clerks working.The store loses money when 7 or more clerks are working.The equation of the trend line is y = -0.36x + 12.6 use the equation to of the trend line to predict the wind chill for a wind speed of 23 mi/h round your answer to the nearest degree. The wind chill at 23 mi/h
Answer:
4°C
Explanation:
Equation: y = -0.36x + 12.6
To find wind chill at 23 mi/hInsert x = 23Simplify
y = -0.36(23)+12.6
y = 4.32°C
y = 4°C (rounded to nearest degree)
Line segment EF begins at (-1,5) and ends at (-1, -3). The segment is translated to the right 4 units and down
2 units to form line segment E'F.
Enter the length, in units, of line segment E'F.
The coordinates for the line segment E'F' are (3, 3) and (3, -5) and the length of the segment E'F' is 8 units.
What is geometric transformation?It is defined as the change in coordinates and the shape of the geometrical body. It is also referred to as a two-dimensional transformation. In the geometric transformation, changes in the geometry can be possible by rotation, translation, reflection, and glide translation.
Line segment EF begins at (-1, 5) and ends at (-1, -3). The segment is translated right 4 units and down 2 units to form line segment E'F'. Then the coordinate of E' and F' will be:
E' = (-1 + 4, 5 – 2) = (3, 3)
F' = (-1 + 4, -3 - 2) = (3, -5)
[tex]\rm d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
The length of the E'F' = √(0 + 64) = 8 units
Thus, the coordinates for the line segment E'F' are (3, 3) and (3, -5) and the length of the segment E'F' is 8 units.

Step-by-step explanation:
arc length is calculated as
arc = circumference × fraction of circle
the angle subtended at the centre of the sector = 360° - 300° = 60° , then
arc = 2πr × [tex]\frac{60}{360}[/tex]
= 2π × 6 × [tex]\frac{1}{6}[/tex]

A cube has a volume of 1000 cubic feet. what is the length of an edge of the cube? show how you found the answer. please help
volume = (side length)³
Alternatively we could say that;
Side length = ∛volume
(we have just found the cube root of both sides here, remember we can do what we like to an equation, as long as we do the same to both sides!)
Because we cubed side length to get volume, side length must be the cubic root of the volume, the ∛.
We know that the volume is 1000 cubic feet, so;
Side length = ∛1000
∛1000 = 10
So the length of an edge of the cube is 10 feet.

Answer:
1. a=3
2. a=3
3. a=9
Step-by-step explanation:
1. 9/a+9-4=12-56/8+3
We move all terms to the left:
9/a+9-4-(12-56/8+3)=0
Domain of the equation: a=0
a∈R
We add all the numbers together, and all the variables
9/a+9-4-8=0
We add all the numbers together, and all the variables
9/a-3=0
We multiply all the terms by the denominator
-3*a+9=0
We add all the numbers together, and all the variables
-3a+9=0
We move all terms containing a to the left, all other terms to the right
-3a=-9
a=-9/-3
a=+3
The potential energy of an object varies jointly with the mass of the object and the height of the object off the ground. a 40-kg object is 2 meters off the ground. the potential energy of the object is 784 joules. a 10-kg object is 3 meters off the ground. what is the potential energy of the 10-kg object? 33 joules 131 joules 294 joules 1,176 joules
The potential energy of the 10-kg object is 294 joules.
What is Variation?Variation is a mathematical term that shows the relationship between two or more parameters or quantities in an equation.
Analysis:
let potential energy be = P
let mass be = m
let height be = h
P ∝ mh
P = kmh
when P = 784, m = 40kg, h = 2 meters
784 = k x 40 x 2
k = 9.8
P = 9.8mh
when m = 10kg, h = 3 meters
P = 9.8 x 10 x 3 = 294 joules.
In conclusion, the potential energy of the object at 3 meter height is 294 joules.

Because it is asking what X value are all the functions equal to just find a point that lies on X that they all come to.
In this case it's 7
Answer:
x = 7
Step-by-step explanation:
The functions are equal to each other where the lines of the functions intersect each other.
The intersection point is (7, 3).
The x-value at this point is 7.
Hence, x = 7.

a right cylinder has a height of 22 1/4ft and a diameter 2 2/5 times it’s height. what is the volume of the cylinder
Answer:
Step-by-step explanation:
Answer:
Check Below
Step-by-step explanation:
given things : 1. height of cone = 22* 1/4 feet or 89/4 feet
2. diameter of cylinder = 2* 2/5 times of height
= 12/5 times of height or 12/5 * 89/4
= 89*3/5 feet
now formula of volume of cone = Pi R² * H
= (3.14) ( D/2)² * H
= (3.14)* (89*3/10)² * 89/4
= (3.14) * (26.7)² * 22.25
= (3.14) * 712.89 * 22.25
= (49806.06)

use Demoiure's Theorem to find (-2-2√3i)³
Let z = -2 - 2√3 i.
Find the modulus of z :
|z| = √((-2)² + (-2√3)²) = √16 = 4
Find the argument of z (note that z lies in the third quadrant):
arg(z) = arctan(2√3/2) - π = arctan(√3) - π = -2π/3
Then in polar form, we have
[tex]z = -2 - 2\sqrt 3\, i = 4 \exp\left(-i\dfrac{2\pi}3\right)[/tex]
By DeMoivre's theorem, the cube of z is
[tex]z^3 = \left(4 \exp\left(-i\dfrac{2\pi}3\right)\right)^3 = 4^3 \exp(-i 2\pi) = \boxed{64}[/tex]
