The slope of a curve is equal to y divided by 4 more than x^2 at any point (x,y) on the curve.
A) Find a differential equation that represents this:
I got dy/dx=y/(4+x^2)
B) Solve this differential equation:
I got y=sqrt((x^4+8x^2+16)/2x)+C
Here is where I really need help!
C) Suppose its known that as x goes to infinity on the curve, y goes to 1. Find the equation for the curve by using part B and determining the constant. Explain all reasoning.
We used the fact that y goes to 1 as x goes to infinity to determine the value of the constant C in the equation we got from part B. This allowed us to find the equation for the curve.
C) To find the equation for the curve given the condition that as x goes to infinity, y goes to 1, we need to use the solution obtained in part B and determine the constant C. Here's how to do it:
As x approaches infinity, we have:
1 = sqrt((x^4 + 8x^2 + 16) / (2x)) + C
Since x is going to infinity, we can consider x^4 to be dominant over the other terms in the numerator, so:
1 ≈ sqrt((x^4) / (2x)) + C
Simplifying the above expression, we get:
1 ≈ sqrt(x^3 / 2) + C
As x goes to infinity, the term sqrt(x^3 / 2) also goes to infinity. For the equation to hold true, C must be equal to negative infinity. However, since C is a constant and not a variable, we cannot consider it to be equal to negative infinity.
Thus, there seems to be a mistake in the solution obtained in part B, as it does not satisfy the given condition in part C. Please double-check the solution and steps taken in part B to ensure the correctness of the answer.

A bakery sells chocolate cupcakes and mocha cupcakes. One day it sold 153 chocolate
and 187 mocha. What percent of the cupcakes sold that day were chocolate?
Answer:
45% of the cupcakes baked on that day were chocolate flavored.
Step-by-step explanation:
Hey there!
We're given that the bakery sold 153 chocolate cupcakes and 187 mocha cupcakes.
Let's find the total number of cupcakes baked in a day.
\(153 + 187 = 340\)Now, we need to find the ratios of the cupcakes. Of the 340 cupcakes baked, 153 were chocolate flavored. Therefore, we can create a ratio between the two values and find the percentage.
Step 1: Define Values
153 chocolate cupcakes baked340 cupcakes in totalStep 2: Create Ratio and Simplify
\(\displaystyle \frac{\text{153 chocolate cupcakes}}{\text{340 total cupcakes}} = \frac{153}{340} = 0.45\)
Step 3: Convert from Decimal Form to Percentage Form
\(0.45 \times 100\% = 45\%\)
Therefore, we have determined that 45% of the cupcakes baked on that day were chocolate flavored.

What is the percent error if a stick of length 60 inches is measured to be 63 inches long?
If a stick of length 60 inches is measured to be 63 inches long the the percent error will be 5% .
The Percent Error can be calculated by the formula
Percent Error = (measured value - actual value)/(actual value) ×100
In the question ,
it is given that
the original length of the stick is 60 inches .
the measured length of the stick is 63 inches .
So, the measured value = 63 inches ,
actual value = 60 inches .
Substituting the measured values and actual value in the percent error formula , we get
Percent Error = (63-60)/60 × 100
= 3/60 × 100
= 1/20 × 100
= 100/20
= 5 %
Therefore , if a stick of length 60 inches is measured to be 63 inches long the the percent error will be 5% .

On solving the provided question, we can say that from given information that - rhombus has four congruent sides, exactly two pairs of congruent opposite angles, and its diagonals are perpendicular
what is rhombus?Rhombuses are quadrilaterals with all four sides being equal in Euclidean plane geometry. Equilateral triangles are rectangles with equal-length sides, also known as equilateral quadrilaterals. By definition, a square is also a rhombus as a rhombus is a quadrilateral with four congruent sides. Greek word rhómbos, which meaning "spinning top," is the source of the English term "rhombus." Its meaning is "bull form," as in the animal's shape. This results in a loud noise and the object attached to the string spinning.
Only two quadrilaterals—the square and rhombus—have four congruent sides among all quadrilaterals. At this point, the square has only right angles, but the rhombus has one opposing pair of obtuse angles. Rhombus is the solution, thus.

2. The tensions T₁, T2 and 7 in a simple framework are given by the equations 5T₁ +3T2 +5T3=70 T₁ +2T₂ +4T3 = 24 4T1 +2T2= 40 Use Guases elimination ONLY to find T₁, T2. T 3.
The value of tensions are:
T₁ = 231/74
T₂ = -329/66
T₃ = 8/33
We can use Gaussian elimination to solve the system of equations:
5T₁ + 3T₂ + 5T₃ = 70
T₁ + 2T₂ + 4T₃ = 24
4T₁ + 2T₂ = 40
First, we'll use the third equation to eliminate T₂ from the first two equations:
4T₁ + 2T₂ = 40 (equation 3)
T₁ + 2T₂ + 4T₃ = 24 (equation 2)
Multiplying the third equation by 2 and subtracting it from the second equation:
T₁ + 2T₂ + 4T₃ = 24 (equation 2)
- 8T₁ - 4T₂ = -80 (2 × equation 3)
------------------------
-7T₁ + 4T₃ = -56
Now we have two equations:
5T₁ + 3T₂ + 5T₃ = 70 (equation 1)
-7T₁ + 4T₃ = -56 (from previous step)
Multiplying the first equation by 7/5 and adding it to the second equation:
5T₁ + 3T₂ + 5T₃ = 70 (equation 1)
-7T₁ + 4T₃ = -56 (from previous step)
------------------------
T₁ + 7T₃ = 14
Now we can use the third equation to eliminate T₂ from the first equation:
4T₁ + 2T₂ = 40 (equation 3)
5T₁ + 3T₂ + 5T₃ = 70 (equation 1)
Multiplying the third equation by 3/2 and subtracting it from the first equation:
4T₁ + 2T₂ = 40 (equation 3)
-11T₁ - T₃ = -35 (3 × equation 3 - 5 × equation 1)
Now we have two equations:
T₁ + 7T₃ = 14 (from previous step)
-11T₁ - T₃ = -35 (from this step)
Multiplying the second equation by -7 and adding it to the first equation:
T₁ + 7T₃ = 14 (from previous step)
74T₁ = 231
Therefore, T₁ = 231/74.
Substituting this value back into the equation T₁ + 7T₃ = 14, we get:
(231/74) + 7T₃ = 14
7T₃ = (74/231) × 20
T₃ = 8/33
Finally, substituting T₁ = 231/74 and T₃ = 8/33 into the equation -11T₁ - T₃ = -35, we get:
-11(231/74) - (8/33) = -329/66
Therefore, T₂ = -329/66.
So, the tensions are: T₁ = 231/74 T₂ = -329/66 T₃ = 8/33

equipotential lines usually don't cross, but under certain circumstances, they can.
In general, equipotential lines do not cross each other. However, there are certain circumstances where they can cross.
Equipotential lines represent regions of equal potential in a physical system, such as electric or gravitational fields. These lines are perpendicular to the field lines and indicate points with the same potential value. Under normal conditions, equipotential lines do not intersect because each line corresponds to a unique potential value, and no two points in a system can have the same potential value.
However, there are situations where equipotential lines can cross. This can occur when there are multiple sources of potential in the system or when the potential varies in a complex manner. In such cases, the equipotential lines may intersect each other, indicating regions with different potential values coming into close proximity.
It is important to note that the crossing of equipotential lines does not violate the basic principles of potential theory. Instead, it reflects the intricate and complex nature of the underlying physical system, where multiple influences or varying potentials can lead to the crossing of equipotential lines.
Therefore, while it is uncommon for equipotential lines to cross, certain circumstances can give rise to such crossings in systems with multiple sources of potential or complex potential variations.

Answer is below. Look at the steps to clearly understand my answer.
Now, the first time to simplifying this to add both sides by 1.
2x - 1 = 8 → 2x - 1 + 1 = 8 + 1
Since we added both sides, we'll now simplify the problem.
Add both numbers.
2x - 1 + 1 = 2x8 + 1 = 92x = 9Lastly, we'll divide both sides of the equation by the same term.
2x = 9\(\frac{2x}{2} =\frac{9}{2}\)Now, cancel both terms that are in both the numerator and denominator.
If you look back at the fraction, 2 is in the numerator and denominator, so we'll cancel those terms.
When you cancelled the terms, you should get x = 9/2.

Hi, there the answer is \(x=\frac{9}{2}\)

F(x)=3x^2+2 the quadratic function g(x) is the function f(x) stretched vertically by a factor of 4. Enter the equation of g(x) in the box
Answer:
g(x) = 12*x^2 + 8
Step-by-step explanation:
For a function f(x), a vertical stretch of scale factor k is defined as:
g(x) = k*f(x)
In this case, we know that f(x) = 3*x^2 + 2
And the function g(x) is the function f(x) vertically stretched by a factor of 4, then we have k = 4
and:
g(x) = 4*f(x)
Replacing by the actual function, we get
g(x) = 4*(3*x^2 + 2)
g(x) = 4*3*x^2 + 4*2
g(x) = 12*x^2 + 8
