Find two additional polar representations of the point. Write each coordinate in simplest form with the angle in
Answer:
The other two other representation are (6 , -4π/3) and (-6 , -π/3)
Step-by-step explanation:
* Lets revise some important facts about the polar form of a point
- In polar coordinates there is an infinite number of coordinates for a
given point
- The point (r , θ) can be represented by any of the following coordinate
pairs (r , θ+2πn) , (-r , θ + [2n+1]π) , where n is any integer
* Now lets solve the problem
∵ A point has polar coordinates (6 , 2π/3)
- We can find many points as the same with this point
- The point (r , θ) can be represented by any of the following coordinate
pairs(r , θ + 2πn) and (-r , θ + (2n + 1)π), where n is any integer.
∵ The angle in [-2π , 2π]
∵ r = 6 and Ф = 2π/3
- Let n = -1
∴ (r , Ф + 2πn) = (6 , 2π/3 + 2π(-1)) = (6 , 2π/3 - 2π) = (6 , -4π/3)
* One point is (6 , -4π/3)
∴ (-r , θ + (2n + 1)π) = (-6 , 2π/3 + (2(-1) + 1)π) = (-6 , 2π/3 + (-2 + 1)π)
∴ (-r , θ + (2n + 1)π) = (-6 , 2π/3 + (-1)π) = (-6 , 2π/3 - π)
∴ (-r , θ + (2n + 1)π) = (-6 , -π/3)
* One point is (-6 , -π/3)
Final answer:
To find two additional polar representations of a point, you can add or subtract 2π radians (or 360° if using degrees) from the original angle, while keeping the radius the same.
Explanation:
A student has asked for two additional polar representations of a point. Polar coordinates specify the location of a point in a plane by a distance from the origin (r) and an angle (φ) with respect to the positive x-axis. To find additional representations, we can add 2π radians to the angle for each full rotation around the circle, keeping the same distance 'r'. For example, if a point has polar coordinates (r, φ), two other representations could be (r, φ + 2π) and (r, φ - 2π), or if in degrees, (r, φ + 360°) and (r, φ - 360°).
Match the polynomials with their factors. 2a2 + 5a − 3 (a + 1)(2a − 3) 2a2 − a − 3 (a − 1)(2a + 3) 2a2 − 5a − 3 (2a − 1)(a + 3) 2a2 + a − 3 (2a + 1)(a − 3)
Answer:
2a² + 5a - 3 = (2a - 1)(a + 3)
2a² - a - 3 = (2a - 3)(a + 1)
2a² - 5a - 3 = (2a + 1)(a - 3)
2a² + a - 3 = (2a + 3)(a - 1)
Step-by-step explanation:
* To factor a trinomial in the form ax² ± bx ± c:
- Look at the c term
# If the c term is positive
∵ c = r × s ⇒ r and s are the factors of c
∴ r and s will have the same sign (sign of b)
∵ a = h × k ⇒ h , k are the factors of a
∴ rk + hs = b
∴ (hx + r)(kx + s) ⇒ if b +ve OR (hx - r)(kx - s) ⇒ if b -ve
# If the c term is negative
∵ c = r × s ⇒ r and s are the factors of c
∴ r and s will not have the same sign
∵ a = h × k ⇒ h and k are the factors of a
∴ rk - hs = b OR hs - rk = b
(hx + r)(kx - s) OR (hx - r)(kx + s)
* Now lets solve the problem
∵ 2a² + 5a - 3
∴ c = -3 ⇒ -ve term
∴ r , s have different sign
∵ 3 = 1 × 3 then r = 1 , s = 3
∵ a = 2
∵ a = h × k
∵ 2 = 2 × 1 then h = 2 , k = 1
∵ rk = 1
∵ sh = 6
∴ sh - rk = 5 ⇒ same value of b
∵ (hx - r)(kx + s)
∴ 2a² + 5a - 3 = (2a - 1)(a + 3)
∵ 2a² - a - 3
∴ c = -3 ⇒ -ve term
∴ r , s have different sign
∵ 3 = 3 × 1 then r = 3 , s = 1
∵ a = 2
∵ a = h × k
∵ 2 = 2 × 1 then h = 2 , k = 1
∵ rk = 3
∵ sh = 2
∴ sh - rk = -1 ⇒ same value of b
∵ (hx - r)(kx + s)
∴ 2a² - a - 3 = (2a - 3)(a + 1)
∵ 2a² - 5a - 3
∴ c = -3 ⇒ -ve term
∴ r , s have different sign
∵ 3 = 1 × 3 then r = 1 , s = 3
∵ a = 2
∵ a = h × k
∵ 2 = 2 × 1 then h = 2 , k = 1
∵ rk = 1
∵ sh = 6
∴ rk - hs = -5 ⇒ same value of b
∵ (hx + r)(kx - s)
∴ 2a² - 5a - 3 = (2a + 1)(a - 3)
∵ 2a² + a - 3
∴ c = -3 ⇒ -ve term
∴ r , s have different sign
∵ 3 = 3 × 1 then r = 3 , s = 1
∵ a = 2
∵ a = h × k
∵ 2 = 2 × 1 then h = 2 , k = 1
∵ rk = 3
∵ sh = 2
∴ rk - sh = 1 ⇒ same value of b
∵ (hx + r)(kx - s)
∴ 2a² + a - 3 = (2a + 3)(a - 1)

In the given right triangle, find the missing length to the nearest tenth.
8.5 ft
7.9 ft
24.1 ft
25 ft
Answer:
25 ft
Step-by-step explanation:
a² + b² = c²
7² + 24² = c²
49 + 576 = c²
c² = 625
c = √625
c= 25
Answer:
D. 25 ft.
Step-by-step explanation:
To find the missing length of any right triangle, you can use the Pythagorean Theorem (A^2+B^2=C^2) to solve. A and B represent the legs (which we do have) and C represents the hypotenuse (which we are trying to find). Insert our known values into the theorem, and we will get 24^2+7^2=C^2. Now we just do the basic math for the numbers that we have (24^2 is 576; 7^2 is 49), and that added up would equal to 625. Now, since C is being squared on the other side, we now have to root both sides. On the side where C is, the radical and the square will cancel out each other, leaving us with just C. But, on the side where 625 is, it should root to 25. Since C is by itself now, the number on the other side (25) will be our answer. Therefore, the missing side is 25 feet long.

Answer: 68%
Step-by-step explanation:
A function g(x) has x-intercepts at (1/2,0) and (6,0) which could be g(x)?
g(x)=2(x+1)(x+6)
g(x) =(x-6)(2x-1)
g(x)=2(x-2)(x-6)
g(x) = (x+6)(x+2)
The answer is g(x)=(x-6)(2x-1).hope this helps please add brainlist
Answer:
[tex]\boxed{g(x) = (x - 6)(2x - 1)}[/tex]
Step-by-step explanation:
An x-intercept is the value of x when g(x) = 0. So, for each function, we must set g(x) = 0 and solve for x.
(a) g(x) = 2(x + 1)(x + 6) = 0
x + 1 = 0 x + 6 = 0
x = -1 x = -6
Wrong.
(b) g(x) = (x - 6)(2x - 1)
x - 6 = 0 2x – 1 = 0
x = 6 2x = 1
x = ½
Right.
(c) g(x) = 2(x - 2)(x - 6)
x - 2 = 0 x - 6 = 0
x = 2 x = 6
Wrong.
(d) g(x) = (x + 6)(x + 2)
x + 6 = 0 x +2 = 0
x = -6 x = -2
Wrong.
The only function that has x-intercepts at (½, 0) and (6, 0) is

3 out of every 5 picks are orange. If 12 picks are orange,how many picks are they in all
Answer: The answer to your question is 20
Step-by-step explanation: We know that 3 out of every 5 picks are oranges. And if the next 12 picks are orange, what is the total number of oranges in all?
So first, you would set up a proportion, which would look like this:
3 oranges/ 5 picks = 12 oranges/ x picks
Let the number of picks be known as x, our variable, since we don't know how many oranges are there total.
Next, when you have a proportion that you are trying to solve, the best thing to do is cross multiply, which will look this:
3x = 12(5)
3x = 60
3x/3 = 60/3
x=20 picks
Therefore, the answer is 20 picks

To write expanded from take each number from left to right and turn all the numbers that are after it into zeros (if there is a decimal then turn the numbers before it into zeros as well)
2 has 4 numbers after it so it gets 4 zeros: 20.00
4 has 2 numbers after it so it gets 2 zeros: 4.00
5 is a decimal that has two numbers before it and one after, so before the decimal there are two zeros, then after the decimal comes the five, then there is one number after the 5 so one zero after the five.
8 is a decimal that has three numbers before it , so before the decimal there are two zeros, then after the decimal is a number that becomes zero then the 8

An angle measures 41 degrees. What is its supplement?
An angle measures 31 degrees. What is its compliment?
Answer:
139 and 59, respectively
Step-by-step explanation:
By definition, supplementary means that the angles all add up to equal 180 degrees. Therefore, 180 - 41 = 139.
By definition, complementary means that the angles all add up to equal 90 degrees. Therefore, 90 - 31 = 59.

During the trip, the Morales family drove on several different highways. Gabriela and Luis noticed that sometimes the mile markers were increasing, and other times the mile markers were decreasing.
On one highway, Gabriela noticed that they passed mile marker 123 at 1:00. She then saw that they reached mile marker 277at 3:00. Since Mr. Morales was driving at a constant speed, their mile-marker location over time can be represented by a line where the time in hours is the independent variable and the mile marker is the dependent variable. The points (1,123) and (3,277) are two points on this line.
What is the value of the slope of this line?
Enter your answer as the correct value, like this: 42
If your answer is a fraction, use the / symbol. For example, if your answer is 314, enter your answer like this: 3/14
Answer:
The slope of the line is 77
Explanation:
We know the speed is constant and that the mile-marker location over time can be represented by a line. This means that the equation is linear.
The slope can, therefore, be calculated as follows:
[tex]slope = \frac{y_2-y_1}{x_2-x_1}[/tex]
where (x₁ , y₁) and (x₂ , y₂) are two points on the line
We are given that the two points (1, 123) and (3, 277) are two points in the line
Substitute with them in the above equation to get the slope as follows:
[tex]slope = \frac{277-123}{3-2}=77[/tex]
Hope this helps :)
The slope of a line represents the rate of change between two variables. The value of the slope in this scenario is 77/2.
The slope of a line represents the rate of change between two variables. In this case, the slope can be calculated using the formula:
slope = (change in y) / (change in x).
Given the points (1,123) and (3,277), the slope can be calculated as follows:
slope = (277 - 123) / (3 - 1).
Therefore, the value of the slope of the line representing the Morales family's mile-marker locations over time is 77/2.

The general form of the equation of a circle is x2+y2−4x−8y−5=0.
What are the coordinates of the center of the circle?
Enter your answer in the boxes.
Answer:
centre = (2, 4)
Step-by-step explanation:
The equation of a circle in standard form is
(x - h)² + (y - k)² = r²
where (h, k) are the coordinates of the centre and r is the radius
Given
x² + y² - 4x - 8y - 5 = 0
Rearrange the x/y terms together and add 5 to both sides
x² - 4x + y² - 8y = 5
Use the method of completing the square on both the x/y terms
add ( half the coefficient of the x/y terms )² to both sides
x² + 2(- 2)x + 4 + y² + 2(- 4)y + 16 = 5 + 4 + 16
(x - 2)² + (y - 4)² = 25 ← in standard form
with centre (2, 4) and r = [tex]\sqrt{25}[/tex] = 5
Andre has enough to fill 3500 in.3.. he decides to change the length of the step so that he will use all of the cement. What will be the new length of the step?
Answer:
43.75 inches or 43 and 3/4 inches.
Step-by-step explanation:
Ok, thanks for the complement of information.
So, to find the volume of that step, which is a rectangular prism, we would use the simple formula:
V = length * width * height
In this case, we have the total volume (3,500 cu in), we have the width (10 inches) and we have the height (8 inches). But we need to find out the new length in order for him to use all 3,500 cu in of cement.
So, we transform the formula above into:
length = V / (width * height)
then we plug-in the numbers:
length = 3,500 / (8 x 10) = 3,500 / 80 = 43.75
So, the new length of the step would be 43.75 inches or 43 and 3/4 inches.

d. the curves intersect at approx. x=3.07
Step-by-step explanation:
the curves intersect at approcx=0.46
Answer:
a. the curves intersect at approx. x=0.46Step-by-step explanation:
The given function is
[tex]log(6x+10)=log_{\frac{1}{2} }x[/tex]
If we graph this function, the result is like the image attached. There you can observe that the intersection point is at (0.464, 1.107).
If we round this points to the nearest hundred, they would be
x = 0.46 and y = 1.11.
Therefore, the right answer is
a. the curves intersect at approx. x=0.46
Find the mean, median, and mode of the date.
4, 8, 11, 6, 4, 5, 9, 10, 10,4
Answer:
Mean: 7.1, median: 7, mode: 4
Step-by-step explanation:
The mean, also known as the average, is equal to the sum of all the numbers divided by how many numbers there are.
4 + 8 + 11 + 6 + 4 + 5 + 9 + 10 + 10 + 4 = 71
10 numbers
71/10 = 7.1
The median is the number in the middle of the set.
4, 4, 4, 5, 6, 8, 9, 10 ,10 ,11
6 and 8 are in the middle, and the number between 6 and 8 is 7.
The mode of a set of numbers is the most common number. In this case, the number is 4 as it appears 3 times.

A 4-digit number ends in 3. If you put the number 3 in the first position, the number will decrease by 738. Find the original 4-digit number.
Answer:
4153. Read the explanation please. There is no point in just reading the answer because the same type of problem can come up in the RSM homework or in a test and you will have no idea how to solve it.
Step-by-step explanation:
Form an equation with the information you know.
1. Moving the last digit, 3, to the first position is the same as doing (x-3)/10 +3000, where x is the original 4-digit number.
Why it works: This expression works because first, you subtract 3 from the original number. This removes 3 from the last digit, but leaves a zero there. To remove the zero, you divide by 10. Finally, to put the 3 at the first position, you add 3000.
2. Since you know that the number will decrease by 738, you can do the second part of forming the equation. Make the expression equal to x - 738, like so --> (x-3)/10 + 3000 = x - 738
Solve the equation.
3. (x-3)/10 + 3000 = x-73
(x-3)/10 = x - 3738
x-3 = 10x - 37380
x = 10x - 37377
-9x = -37377
