What are 3 other points that take you to the same location as (6, -4pi/3)
Answer:
P1 (6, 2/3 π)
P2 (6, 10/3 π)
P3 (6, 14/3 π)
Step-by-step explanation:
To find the other three points you take into account that if you sum 2π to one coordinate you have the same point.
Hence, by adding 2π to -4π/3, and again other two times:
[tex]-\frac{4}{3}\pi+2\pi=\frac{2}{3}\pi\\\\\frac{2}{3}\pi+2\pi=\frac{8}{3}\pi[/tex]
[tex]\frac{8}{3}\pi+2\pi=\frac{14}{3}\pi[/tex]
hence, the other two points are
P1 (6, 2/3 π)
P2 (6, 10/3 π)
P3 (6, 14/3 π)

Find the unknown side of the triangle below
A. 4cm
B. 3cm
C. 9cm
D. 19cm
Answer:
C - 9 cm
Step-by-step explanation:
We can use the Pythagorean theorem to figure out the missing side length, in this case, X.
The Pythagorean theorem states: a^2 + b^2 = c^2, with c being the hypotenuse. We have the side length of the hypotenuse which is 15, and we have another side length of 12. Let's put these back in our equation:
a^2 + 12^2 = 15^2;
If we simplify the squares by simply doing them: a^2 + 144 = 225;
Now let's subtract 144 from both sides to isolate the variable, a:
a^2 = 81;
Now we square both sides to find a:
a = 9
The missing side length is 9 cm.
Which equation is equivalent to f(x) = -3(x-2)2 + 14?
The given function f(x) = -3(x-2)^2 + 14 is a quadratic equation shown in vertex form. To find an equivalent equation in standard form or solve for its roots, one can expand and simplify or use the quadratic formula with the appropriate coefficients.
The equation f(x) = -3(x-2)^2 + 14 is a quadratic equation in vertex form. In standard form, a quadratic equation is represented as at^2 + bt + c = 0. To express f(x) in this standard form, we simply need to expand the squared term and simplify. The given equation already shows that the parabola has been reflected vertically due to the negative sign before the coefficient of the squared term, and it is shifted 2 units to the right and 14 units up from the origin.
Transformations of the independent variable such as multiplying by a constant or adding a number, like in f(2x) or f(-2x), will affect the graph of the quadratic function. They result in horizontal scaling or reflection, while transformations like f{-2(x+1)} involve horizontal shifting.
To solve a quadratic equation that is set equal to zero, we can use the quadratic formula, which employs the coefficients a, b, and c. As an example, for a quadratic equation with constants a = 4.90, b = 14.3, and c = -20.0, the roots can be found through this formula.

Use the information to write an equation with variables on both sides. Let x represent Kim’s age.
Bob is 4 years older than twice Kim’s age.
Paul is 1 year younger than 3 times Kim's age.
Bob and Paul are the same age.
Which equation can be used to determine Kim’s age, x, from the information about Bob and Paul?
4x + 2 = 3x + 1
4x + 2 = 3x + (–1)
2x + 4 = 3x + 1
2x + 4 = 3x + (–1)
Hey! I hope this helps!
Answer:2x + 4 = 3x+ (-1)
Option D)
Step-by-step explanation:We are given the following in the question:
Let x represent Kim's age
"Bob is 4 years older than twice Kim's age"
Thus, Bob's age =
4 + 2x years
"Paul is 1 year younger than 3 times Kim's age."
Thus. Paul's age is
(3x - 1) years
If Bob's age and Paul's age is equal, we can write:
2x + 4 = 3x + (-1)
Thus, the required expression is
2x + 4 = 3x + (-1)Option D)
Option D! 2x + 4 = 3x + (-1)The equation can be used to determine Kim’s age will be 2x + 4 = 3x + (–1). Then the correct option is D.
What is the linear system?A linear system is one in which the parameter in the equation has a degree of one. It might have one, two, or even more variables.
Use the information to write an equation with variables on both sides. Let x represent Kim’s age.
Bob is 4 years older than twice Kim’s age. Then the age of the Bob will be in terms of x.
B = 2x + 4
Paul is 1 year younger than 3 times Kim's age. Then the age of the Paul will be in terms of x.
P = 3x – 1
Bob and Paul are the same age.
B = P
Put the value of B and P, then we have the equation will be
2x + 4 = 3x – 1
2x + 4 = 3x + (–1)
Then the correct option is D.

A bag contains 39 coins consisting of quarters and nickels the total value of the coins is $6.35 which system of equation can be used to used to determine the number of quarters Q and the number of nickels n In the bag
Answer:
The system of equation to determine the quantity of nickels and quarters is simultaneous equation.
Nickels = 17
Quarters = 22
Step-by-step explanation:
Given
Let n represent number of nickels
Let q represent number of quarters
From line 1 of the question, we understand that
Total coins = 39
So, n + q = 39 because the made up of the nickels and the quarters
It's also stated that the total value of these 39 coins is $6.35.
First, it should be noted that
1 nickel is worth 0.05 and 1 quarter is worth 0.25, we can represent the total value of the coins with the following equation
0.05n + 0.25q = 6.35
At this point, we have two equation such can be solved simultaneously
n + q = 39 ------- (1)
0.05n + 0.25q = 6.35 ------- (2)
So, the system of equation to determine the quantity of nickels and quarters is simultaneous equation.
Solving further.....
Make q the subject of formula in equation (1)
q = 39 - n
Substitute 39 - n for q in equation 2
0.05n + 0.25q = 6.35 becomes
0.05n + 0.25(39 - n) = 6.35
0.05n + 9.75 - 0.25n = 6.35
Collect like terms
0.05n - 0.25n = 6.35 - 9.75
-0.2n = -3.4
Divide through by -0.2
-0.2n/-0.2 = -3.4/-0.2
n = 17
Recall that q = 39 - n
Substituton 17 for n in this equation
q = 39 - 17
q = 22
Hence, there are 17 nickels and 22 coins

Surface area of the rectangular prism = 22 m²
What is the lateral Area of a Rectangular Prism?Lateral area = 2(l + w)h
What is the Surface Area of a Rectangular Prism?Surfacea area = 2(wl+hl+hw)
We are given a rectangular prism that has the following dimensions:
Length (l) = 1 m
Width (w) = 3 m
Height (h) = 2 m
Area of each bases = l × w = 1 × 3 = 3 m²
Area of the right and left lateral faces = 1 × 2 = 2 m²
Area of the front and back lateral faces = 2 × 3 = 6 m²
Lateral area of the rectangular prism = 2(l + w)h = 2(1 + 3)2 = 16 m²
Surface area of the rectangular prism = 2(wl+hl+hw) = 2(3 × 1 + 2 × 1 + 2 × 3) = 22 m²

The area of Brian's cake's top = base x height
= 13 x 9
= 117 square inches
Area of Nancy's cake's top = [tex]\frac{1}{2\\}[/tex] x base x height
= [tex]\frac{1}{2}[/tex] x 15 x 12
= 6 x 15
= 90 square inches
Therefore, Brian's cake's top has a greater area than Nancy's.
Answer:
Brian's parallelogram-shaped cake top had the greater area. It was 27 in² greater than Nancy's cake top.
Step-by-step explanation:
To find the area of a parallelogram, use the formula A = b × h, where A is the area, b is the base and h is the height. Substitute the base and height into the equation.
A = 13 × 9
Then work out the equation to get:
117 = 13 × 9
This means that Brian's cake top has an area of 117 in².
Next, find the area of a triangle using the formula A = [tex]\frac{bh}{2}[/tex], where A is the area, b is the base, and h is the height. Substitute the base and height into the equation.
A = [tex]\frac{15*12}{2}[/tex]
The * symbol means the same as multiply.
Then work out the equation to get:
180 = [tex]\frac{15*12}{2}[/tex]
This means that Nancy's cake top has an area of 90 in².
We can see that Brian's cake top has a greater area than Nancy's already, but to find out how much greater, just subtract 90 from 117:
117 - 90 = 27
Hence, Brian's cake top has a greater area of 27 in².

hurry plzzzzz!!!!!!!!!!!!! Find the height of a square pyramid that has a volume of 75 cubic feet and a base length of 5 feet. A:5 feet B:9 feet C:25 feet D:45 feet
Answer:
B
Step-by-step explanation:
The volume of a square pyramid can be found using:
v=1/3 bh
Where b is the area of the base, and h is the height
First, let's find the area of the base
a=l*l
We know the length is 5, so we can substitute it in
a=5*5
a=25
Now we know b(area), is 25, and we know the volume is 75, so we can substitute them in
v=1/3 bh
75=1/3(25)h
Divide both sides by 1/3, or multiply both sides by the reciprocal, 3/1
225=25h
Divide both sides by 25
h=9
So, the height is 9 feet , or choice B

−3(n + 9) = 3
The solution is n = ______.
Answer: n = -10
Step-by-step explanation:
-3(n+9) = 3
-3n - (-27n) = 3
-30n = 3
n = -10
Answer:
n = -10
Step-by-step explanation:
Distribute -3 to n and 9. This makes -3n - 27 = 3. Add 27 to both sides, giving you -3n = 30. Divide -3 from both sides. This makes n = -10.
