Answer: The Correct answer is E (2,pie/6)
Step-by-step explanation:
To find the polar coordinates of a point given its Cartesian coordinates (x, y), we can use the following formulas:
r = √(x^2 + y^2)
θ = atan2(y, x)
where r is the radial distance from the origin to the point, and θ is the angle measured counterclockwise from the positive x-axis to the line connecting the origin and the point.
Given the Cartesian coordinates (x, y) = (√3, 1), we can plug these values into the formulas to find the polar coordinates:
r = √(√3^2 + 1^2) = √(3 + 1) = 2
θ = atan2(1, √3)
Using a calculator, we can find that θ is approximately 0.5236 radians.
So, the polar coordinates of the point (√3, 1) are (r, θ) = (2, 0.5236 radians).

7 root 98 + 3 root 242 divided by 6 root 50
The expression (7√98 + 3√242) divided by 6√50 simplifies to the fraction of 4/3.
To simplify the expression (7√98 + 3√242) ÷ 6√50, we need to rationalize the denominator. This means we need to simplify the expression in such a way that there are no radical signs in the denominator. To do this, we can use the fact that the product of a radical and its conjugate is a rational number.
First, let's simplify the terms under the radicals by factoring out the perfect squares:
√98 = √(49*2) = 7√2
√242 = √(121*2) = 11√2
Now the expression becomes:
(7√2 + 311√2) ÷ (6√(252))
= (7√2 + 33√2) ÷ (6*5√2)
= 40√2 ÷ 30√2
= 4/3
In conclusion, to simplify expressions involving radicals, we need to factor out perfect squares and use the property of the conjugate to rationalize the denominator.

If company's marginal cost function is c(x)= 14 / √x, the total cost of producing the first 25 units is $10.67.
The marginal cost function is given as c(x) = 14 / √x, where x is the number of units produced.
To find the total cost of producing the first 25 units, we need to integrate the marginal cost function from x=0 to x=25, as follows:
Total cost = ∫₀²⁵ 14 / √x dx
We can use integration by substitution to solve this integral. Let u = √x, then du/dx = 1/(2√x), and dx = 2u du. Substituting these into the integral, we get:
Total cost = ∫₀⁵ √14/u du
This can be integrated using the power rule of integration. We have:
Total cost = 2√14 [[tex]u^{(3/2)[/tex]/3]₀⁵
Substituting back u = √x, we get:
Total cost = 2√14 [[tex](\sqrt{x})^{(3/2)[/tex]/3]₀²⁵
= 2√14 [[tex](\sqrt{25})^{(3/2)[/tex]/3 - [tex](\sqrt{0})^{(3/2)[/tex]/3]

Michel-Eugène Chevreul found that the greatest intensity came from placing ________colors next to each other.
tertirary
analogous
complementary
arbitrary
Answer:
C. complementary
Michel-Eugène Chevreul discovered that placing complementary colors next to each other can create the greatest contrast and vibrancy in color perception. This is because complementary colors are located opposite each other on the color wheel and, when placed side by side, they enhance each other and create a strong visual impact. For example, placing yellow next to violet or blue next to orange can create a dynamic and eye-catching effect. In contrast, placing tertiary colors (colors made by mixing primary and secondary colors) or arbitrary colors next to each other may not create as much contrast or visual interest. Overall, understanding color theory and the relationships between different colors can be helpful for creating visually appealing designs, artworks, or other color-based projects.
Yui is buying beverages for her friends. She buys a total of 6 bottles of water and sports drinks. Bottles of water cost $1.50 each, and sports drinks cost $2.50 each, she spends a total of $10. Write a system of equations to represent the information, and use substitution to determine how many of each type of drink yui buys
Answer:
Let x be the number of bottles of water that Yui buys, and let y be the number of sports drinks she buys.
Since Yui buys a total of 6 bottles of water and sports drinks, we know that:
x + y = 6
We also know that each bottle of water costs $1.50 and each sports drink costs $2.50, and that Yui spends a total of $10. Therefore, we can write another equation based on the total cost:
1.5x + 2.5y = 10
We now have a system of two equations with two variables:
x + y = 6
1.5x + 2.5y = 10
To solve for x and y, we can use substitution. Rearranging the first equation, we get:
x = 6 - y
Substituting this expression for x into the second equation, we get:
1.5(6 - y) + 2.5y = 10
Expanding and simplifying, we get:
9 - 1.5y + 2.5y = 10
Combining like terms, we get:
y = 2
Substituting this value of y back into the equation x + y = 6, we get:
x + 2 = 6
Solving for x, we get:
x = 4
Therefore, Yui buys 4 bottles of water and 2 sports drinks.
The vector (6,-5) is reflected across the line y=x, and the resulting matrix is dilated by a scale of -1.5
(7.5, -9) is the final value after reflection and dilation.
To reflect a vector across the line y=x, we switch the x and y coordinates. Therefore, the reflection of (6,-5) across the line y=x is (-5,6).
To dilate a vector by a scale of -1.5, we multiply the vector by -1.5. Therefore, the resulting vector is (-5,6) multiplied by -1.5, which gives us:
(-5,6) * (-1.5) = (7.5, -9)
So the final result after the reflection and dilation is (7.5, -9).

The definition of the iterative process is:
xₙ ₊ ₁ = 4xₙ(3 - xₙ)
From the given information,
x₀ = 5
To determine the value of x₁, we will substitute n = 0
xₙ ₊ ₁ = 4xₙ(3 - xₙ)
x₀ ₊ ₁ = 4x₀(3 - x₀)
x₁ = 4x₀(3 - x₀)
Substitute x₀ = 5
x₁ = 4(5)(3 - 5)
x₁ = 20(-2)
x₁ = -40
To determine the value of x₂, we will substitute n = 1
xₙ ₊ ₁ = 4xₙ(3 - xₙ)
x₁ ₊ ₁ = 4x₁(3 - x₁)
x₂ = 4x₁(3 - x₁)
Substitute x₁ = -40

The measure of the angle of the triangle ∠BCD = 13°
Given data ,
Let the triangle be represented as ΔBCD
Now , in triangle BCD, we are given the following angle measurements:
angle CDE = (9x - 12)°
angle BCD = (2x + 3)°
angle DBC = (3x + 5)°
From the exterior angle theorem , we get
∠CDE = ∠BCD + ∠DBC
On simplifying , we get
9x - 12 = 2x + 3 + 3x + 5
9x - 12 = 5x + 8
Subtracting 5x on both sides and adding 12 , we get
4x = 20
Divide by 4 on both sides , we get
x = 5
