heyyo does anyone knows how to solve this equation and the answer as well??
Answer:
A
Step-by-step explanation:
tanΘ = [tex]\frac{\sqrt{3} }{3}[/tex] , then
Θ = [tex]tan^{-1}[/tex] ( [tex]\frac{\sqrt{3} }{3}[/tex] ) = [tex]\frac{\pi }{6}[/tex]
since tanΘ > 0 then Θ is in first / third quadrants
Θ = π + [tex]\frac{\pi }{6}[/tex] = [tex]\frac{7\pi }{6}[/tex]
solution is { [tex]\frac{\pi }{6}[/tex] , [tex]\frac{7\pi }{6}[/tex] } in the interval 0 < Θ < 2π
Is this a function pls someone tell me
The quotient of c and 6 is greater than or equal to -20
Translate the sentence into an inequality.
Answer:
c/6 ≥ -20
Step-by-step explanation:
The quotient of c and 6 basically means c divided by 6 (minor note: we also go by the order it's written in). We place in '≥' in this inequality because, greater than means '>' and the line underneath it signifies an equal to sign, and as a result of this, we get -20.

Which of the following polynomials has solutions that are not real numbers?
x2 - 6x +3
x2 + 4x +3
-X2 - 9x - 10
x2 + 2x + 3
Answer:
4
Step-by-step explanation:
Answer:
Option 4 is correct.
Step-by-step explanation:
To find: Polynomial whose solution are not real numbers.
Given Polynomials are Quadratic Polynomial.
So, we can check if solution of quadratic polynomial by find & checking value of discriminant.
Standard form of Quadratic polynomial is given by
ax² + bx + c
then Discriminant, D = b² - 4ac
If, D > 0 ⇒ Solutions are distinct real numbers
if, D = 0 ⇒ Solutions are equal real numbers
if, D < 0 ⇒ Solutions are not real numbers (They are complex conjugates)
Option A:
By comparing with standard form
a = 1 , b = -6 , c = 3
D = (-6)² - 4 × 1 × 3 = 36 - 12 = 24 > 0
Thus, Solutions are Real numbers.
Option B:
By comparing with standard form
a = 1 , b = 4 , c = 3
D = (4)² - 4 × 1 × 3 = 16 - 12 = 4 > 0
Thus, Solutions are Real numbers.
Option C:
By comparing with standard form
a = -1 , b = -9 , c =-10
D = (-9)² - 4 × (-1) × (-10) = 81 - 40 = 41 > 0
Thus, Solutions are Real numbers.
Option D:
By comparing with standard form
a = 1 , b = 2 , c = 3
D = (2)² - 4 × 1 × 3 = 4 - 12 = -8 < 0
Thus, Solutions are not Real numbers.
Therefore, Option 4 is correct.

well, we know that he makes $60 weekly, that'd be the 100%, we also know that he saves 30% of that and the rest, well, 100% - 30% = 70%, so 70% he spends it on food.

[tex]\begin{array}{ccll} amount&\%\\ \cline{1-2} 60 & 100\\ x& 70 \end{array} \implies \cfrac{60}{x}=\cfrac{100}{70}\implies \cfrac{60}{x}=\cfrac{10}{7} \\\\\\ 420=10x\implies \cfrac{420}{10}=x\implies 42=x[/tex]

Answer:
Area of shaded rectangle = 42 cm²
55%
Step-by-step explanation:
The length of the shaded area is equal to the length of the white rectangle.
Therefore, length of shaded rectangle = 7 cm
The width of the shaded rectangle is equal to the length of the white rectangle minus two widths of the white rectangle.
Therefore, width = 7 - (2 x 0.5) = 6 cm
Area of shaded rectangle = width x length
= 6 x 7
= 42 cm²
----------------------------------------------------------------------------------------------
Perimeter of a square = 4 × side length
If the perimeter of the square is 40 cm,
then the side length = 40 ÷ 4 = 10 cm
Area of a square = side length x side length
⇒ area of this square = 10 x 10 = 100 cm²
To determine the shaded area, calculate the areas of the 2 white triangles and subtract these from the area of the square.
Area of a triangle = 1/2 x base x height
⇒ area of left triangle = 1/2 x (10 - 7) x 10 = 15 cm²
⇒ area of right triangle = 1/2 x 10 x (10 - 4) = 30 cm²
Therefore, shaded area = 100 - 15 - 30 = 55 cm²
To calculate the percentage, divide the shaded area by the area of the square and multiply by 100:
(55 ÷ 100) × 100% = 55%

James correctly proves the similarity of triangles DAC and DBA as shown.
HELP PLSSSS ASAP
Answer:
AA similarity postulate
Step-by-step explanation:
Triangles are similar if corresponding angles are congruent or if corresponding sides are proportional.
Here, the missing reason in the proof follows a step in which two angles are shown congruent. That means you can claim similarity by the AA similarity postulate.
__
Additional comment
The similarity postulates include ...
AA -- two corresponding angles (the third angle is determined by these two)
SSS -- three proportional corresponding sides
AAS -- two congruent angles and a proportional corresponding side
ASA -- a variation of AAS
SAS -- proportional corresponding sides flanking a congruent angle
With the exception of AA, these are the same postulates as used to prove triangle congruence when the corresponding sides are congruent, rather than proportional.

Answer:
The price for each pound of tuna is not always the same.
Step-by-step explanation:
What we do is divide the price by the amount of tuna to find the price for each amount of tuna
For the 1st one, we have $8 for 2 tuna so we do 8/2
8/2 = 4
For the 2nd we have $16 for 4 so we do 16/4
16/4 = 4
For the 3rd, we have $27 for 9 so we do 27/9
27/9 = 3

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 what price the widgets should be sold for, to the nearest cent, for the company to make the maximum profit. y=-6x^2+190x-826
Answer:
The maximum profit is $854
Step-by-step explanation:
Profit is the difference between the revenue and the cost price of an item. It is given by:
Profit = selling price - cost price
Since x represent the profit made by the company, is related to the selling price of each widget, x and it is given by the formula:
y = -3x² + 155x - 1148
At maximum profit, dy/dx = 0, hence:
dy/dx = -6x + 155
0 = -6x + 155
6x = 155
x = 25.83
The maximum profit is at gotten when the selling price of each widget is 25.83. Hence:
y = -3(25.83)² - 155(25.83) - 1148
y = $854
Therefore the maximum profit is $854
Karen's mom is filling 12 birthday hats with candy for her birthday party. Each hat is shaped like a cone with a height of 6 inches and a radius of 3 inches.
Which statements are true? Choose all that are correct.
The volume of each birthday hat is 56.55 in³ and the 12 hats has a total volume of 678.58 in³
What is volume?
Volume is the amount of space occupied by a three dimensional shape or object.
The volume of a cone is given by:
volume = (1/3) * π * radius² * height
The cone that has a height of 6 inches and a radius of 3 inches. Hence:
Volume = (1/3) * π * 3² * 6 = 56.55 in³
For 12 hats:
Volume = 12 * 56.55 in³ = 678.58 in³

I don't understand this
Answer: (2,1)
Step-by-step explanation:
The two equations given are:
y = 3 -x
y = x - 1
The question is asking to determine the point of intersection for two linear functions aka two lines.
Step #1: Both functions must be in slope intercept form which is y = mx+b. In this case, this step can be skipped because both functions are in slope form. At an intersection, x and y must have the same value for each equation. This means that the equations are equal to each other. Therefore, we can set both equations equal to each other to solve for x.
Add x to both sides to get 2x - 1 = 3Add 1 to both sides to get 2x = 4Divide both sides by 2 to get x = 2Step #2: We found the x-coordinate, but we need to find the y-coordinate. We know that the x-coordinate is 2, so substitute the number 2 into any of the given equations. So, either into y = 3 - x or y = x - 1.
The point of intersection is (2,1).

Which of the following correctly measures the length (in cm) of the green box shown in the image below?
0.920 cm
0.92cm
0.9cm
Answer:
0.92 cm
Step-by-step explanation:
Do not pick 0.920 as it is the same as 0.92 but 0.92 is always the preferable option
The accurate measurement for the length of the green box is indeed 0.92 cm.
To measure the length of the green box accurately, we must carefully analyze the given image. By comparing the green box to the provided scale, we can deduce the correct measurement.
Upon examination, the green box appears to span almost the entirety of the "0.1 cm" scale division and extends slightly beyond it. Given that the box reaches around 9 divisions on the scale, it is reasonable to deduce that its length is 0.92 cm. This is because it's covering 9 divisions of 0.1 cm each, and considering the small extension.
Hence, the accurate measurement for the length of the green box is indeed 0.92 cm. This value takes into account its coverage of 0.9 cm (9 divisions) and a slight extension, aligning with the provided options.
