How do you plot the polar coordinate ( − 3 , − π 3 ) ?
Answers
9514 1404 393
Answer:
see attached (black dot)
Step-by-step explanation:
We assume you want to plot (r, θ) = (-3, -π/3), where the angle is in radians.
The basic idea is to locate the ray that is in the direction -π/3 radians, then go 3 units in the opposite direction. The point (3, -π/3) is identified in the attached graph by a red circle. Its reflection across the origin is how you plot the point for a negative radius. That reflected point is the black dot.
The equivalent coordinates are ...
(r, θ) = (-(-3), -π/3+π) = (3, 2π/3)

Some simplify this plz 12x + 1.5x - 2-7
Answers
Answer:
13.5x + 5
Step-by-step explanation:
12x + 1.5x - 2 - 7 (you always want to work left to right)
13.5x - (2 - 7) (you are free to use the associative property here to isolate like terms)
13.5x - (-5) (remember a number less in value subtracted from a higher value will result in a negative value; giving you this value for instance.)
13.5x + 5 (now since it was basically subtracting a negative from 13.5x you can technically say the same thing by turning the negative value to a positive however you must do the opposite of subtraction as well.)

y = 3( [tex]0.5^{x}[/tex] )
Step-by-step explanation:
Exponential function has the form f(x) = k [tex]b^{x}[/tex] where b > 0 and b ≠ 1
~~~~~~
3 = k × [tex]b^{0}[/tex] ⇒ k = 3
1.5 = 3( [tex]b^{1}[/tex] ) ⇒ b = 0.5
Thus, y = 3( [tex]0.5^{x}[/tex] )

A company sells widgets. The amount of profit, y, made by the company, is related to
the selling price of each widget, x, by the given equation. Using this equation, find out
the maximum amount of profit the company can make, to the nearest dollar.
y = -8x2 + 242x – 1056
Answers
Answer:
774 dollars
Step-by-step explanation:
Given the amount of profit, y, made by the company, is related to
the selling price of each widget, x, by the given equation
y = -8x^2 + 242x – 1056
The company made her maximum profit when dy/dx = 0
dy/dx = -16x + 242
0 = -16x + 242
16x = 242
x = 242/16
x = 15.125
Get the maximum amount of the profit
Substituting x = 15.125 into the function we have:
y = -8(15.125)^2 + 242(15.125) – 1056
y = -8(228.77)+3,660.25-1056
y = -1,830.09+3,660.25-1056
y = 773.91
Hence the maximum amount of profit the company can make, to the nearest dollar is 774 dollars
(20,-8); 7x - 4y = -5
Answers
The question is incomplete.
However, from the given parameters, a likely question could be to:
1. Write an equation in slope intercept form through (20,-8) and is parallel to 7x - 4y = -5
or
2. Write an equation in slope intercept form through (20,-8) and is perpendicular to 7x - 4y = -5
Answer:
See Explanation
Step-by-step explanation:
First, we calculate the slope of [tex]7x - 4y = -5[/tex]
[tex]7x - 4y = -5[/tex]
Subtract 7x from both sides
[tex]7x-7x - 4y = -5-7x[/tex]
[tex]- 4y = -5-7x[/tex]
Make y the subject
[tex]\frac{- 4y}{-4} = \frac{-5-7x}{-4}[/tex]
[tex]y = \frac{-5-7x}{-4}[/tex]
[tex]y = \frac{5+7x}{4}[/tex]
[tex]y = \frac{5}{4}+\frac{7}{4}x[/tex]
[tex]y = \frac{7}{4}x+\frac{5}{4}[/tex]
The general format of an equation is:
[tex]y= mx + b[/tex]
Where
[tex]m = slope[/tex]
By comparison:
[tex]m = \frac{7}{4}[/tex]
Solving (1): Parallel
Here, we assume that the line is parallel to the given equation.
And as such, it means that they have the same slope
So, we have:
[tex](x_1,y_1) = (20,-8)[/tex]
and
[tex]m = \frac{7}{4}[/tex]
The equation is then calculated as:
[tex]y - y_1 = m(x - x_1)[/tex]
This gives:
[tex]y - (-8) = \frac{7}{4}(x - 20)[/tex]
[tex]y +8 = \frac{7}{4}(x - 20)[/tex]
Open bracket
[tex]y +8 = \frac{7}{4}x - \frac{7}{4}*20[/tex]
[tex]y +8 = \frac{7}{4}x - 7*5[/tex]
[tex]y +8 = \frac{7}{4}x - 35[/tex]
Make y the subject
[tex]y = \frac{7}{4}x - 35-8[/tex]
[tex]y = \frac{7}{4}x -43[/tex]
Solving (2): Perpendicular
Here, we assume that the line is perpendicular to the given equation.
And as such, it means that the following relationship exists between their slope:
[tex]m_2 = -\frac{1}{m_1}[/tex]
Where
[tex]m_1 =m =\frac{7}{4}[/tex] -- as calculated above
Substitute 7/4 for m1 in [tex]m_2 = -\frac{1}{m_1}[/tex]
[tex]m_2 = -\frac{1}{7/4}[/tex]
[tex]m_2 = -\frac{4}{7}[/tex]
So, we have:
[tex](x_1,y_1) = (20,-8)[/tex]
and
[tex]m_2 = -\frac{4}{7}[/tex]
The equation is then calculated as:
[tex]y - y_1 = m(x - x_1)[/tex]
This gives:
[tex]y - (-8) = -\frac{4}{7}(x - 20)[/tex]
[tex]y +8 = -\frac{4}{7}(x - 20)[/tex]
Open bracket
[tex]y +8 = -\frac{4}{7}x + \frac{4}{7}*20[/tex]
[tex]y +8 = -\frac{4}{7}x + \frac{80}{7}[/tex]
Make y the subject
[tex]y = -\frac{4}{7}x + \frac{80}{7}-8[/tex]
[tex]y = -\frac{4}{7}x + \frac{80-56}{7}[/tex]
[tex]y = -\frac{4}{7}x + \frac{24}{7}[/tex]
Take LCM
[tex]y = \frac{-4x + 24}{7}[/tex]

can someone please help? the question is an equilateral triangle is sometimes/always/never similar to a scalene triangle, because we can sometimes/always/never map one onto the other using only dial actions rigid transformations.
Answers
Answer:
An equilateral triangle is never similar to a scalene triangle, because we can never map one onto the other using only dilations and rigid transformations.
======================================================
Explanation:
An equilateral triangle is one where it has all three sides the same length. "Equi" means "equal" while "lateral" means "side". Any equilateral triangle also has all three angles the same measure (we consider it equiangular). Each angle is 60 degrees.
In contrast, a scalene triangle has all of its sides different, so consequently that means all of its three angles must be different as well. If you had exactly two angles congruent to one another, then the opposite sides would be a congruent pair of sides, but then that leads to an isosceles triangle. Also, if all three angles were the same, then we'd get back to an equilateral triangle. So in short, any scalene triangle has all of its angles different.
------------------
Let's consider two cases
Case 1) The scalene triangle has one angle that is 60 degrees, while the other two angles are not 60 degrees.Case 2) The scalene triangle doesn't have any angles that are 60 degrees.If case 1 happens, then we could match up one pair of 60 degree corresponding angles between the equilateral triangle and the scalene triangle. However, we won't have any more matches. This is because the other two angles aren't 60 (if they were then the triangle isn't scalene). Therefore case 1 leads to dissimilar triangles.
If case 2 happens, then we get the same conclusion as case 1. This time we don't have any angles matching up. Similar triangles must have corresponding angles match up and be congruent. Put another way: similar triangles are the same shape but not necessarily the same size.
------------------
After completing both cases, we can see that it is impossible to have an equilateral triangle be similar to a scalene triangle. In terms of transformations, we cannot apply any of the following
TranslationReflectionRotationDilationand have one triangle turn into the other. Again, it's all because the angles do not match up. We may have one matching pair, but we need all three pairs to match.

Enny is selling candles for $3 each at a fund-raiser. If she starts selling with $4 to help her make change, how many candles, x, will she have to sell to end up with $19?
Answers
Answer:
5 candles
Step-by-step explanation:
Enny is selling candles for $3 at a fund raiser
She starts selling $4 to help her make change
Therefore the number of candles x that will be sold to get $19 can be calculated as follows
3x + 4= 19
3x = 19-4
3x= 15
x = 15/3
x= 5
Hence 5 candles must be sold to get $19

Answers
C. 1/4
There is a table with 36 possible outcomes. 9 of them are desired outcomes because they have an even number rolled first and then an odd number rolled second (a few random examples from the table would be 2,1, 2,3, 4,1, 4,5, 6,3 etc.)
All we have to do is make a fraction of the desired outcomes over the total number of possible outcomes. 9/36. That can be simplified into 1/4 and voilà, there is your answer.

The of getting an even number in first and an odd number second is 1/4.

I need to solve the equation 6n + 21 = - 3 - 2n
Answers
Answer:
n= -3
Step-by-step explanation:
First, your're going to subtract from both sides
6n + 21 - 2 1= -3 - 2n - 21
Then simplify
6n = -2n - 24
Then add 2n on both sides
6n + 2n = -2n -24 + 2n
Simplify again
8n = -24
Then divide both sides by 8
8n/8 = -24/8
Then simplify and this is your answer
n= -3
