2x² + 5x, what will it a Perfect Square? make
Answers
Answer:
2x² + 5x + c = 0
For this quadratic equation to have one double root, the discriminant must equal 0.
5² - 4(2)(c) = 0

B) The recipe will need 16 cups of sauce and 4 teaspoons of oregano for 8 servings.
C) The recipe will need 14 cups of sauce and 4 teaspoons of oregano for 8 servings.
D) The recipe will need 14 cups of sauce and three and a half teaspoons of oregano for 8 servings.
Answers
The correct answer is A) The recipe will need 16 cups of sauce and three and a half teaspoons of oregano for 8 servings.
To determine the amount of sauce and oregano needed to make 8 servings, we can use the ratio of sauce to oregano from the table.
According to the table, for 3 servings, 6 cups of sauce are used along with 1 & 1/2 teaspoons of oregano. We need to find the ratio of sauce to oregano to scale it up for 8 servings.
Ratio of sauce to oregano:
6 cups of sauce / 1 & 1/2 teaspoons of oregano = 6/1.5 = 4 cups of sauce per teaspoon of oregano
Now, for 8 servings, we need to multiply the ratio by the number of teaspoons of oregano required:
8 servings * 1 teaspoon of oregano = 8 teaspoons of oregano
Therefore, for 8 servings, we would need:
8 teaspoons of oregano * 4 cups of sauce per teaspoon of oregano = 32 cups of sauce
Therefore, the correct answer is A) The recipe will need 16 cups of sauce and three and a half teaspoons of oregano for 8 servings.

What is Trigonometric Functions?
Trigonometry uses six fundamental trigonometric operations. Trigonometric ratios describe these operations. The sine function, cosine function, secant function, co-secant function, tangent function, and co-tangent function are the six fundamental trigonometric functions. The ratio of sides of a right-angled triangle is the basis for trigonometric functions and identities. Using trigonometric formulas, the sine, cosine, tangent, secant, and cotangent values are calculated for the perpendicular side, hypotenuse, and base of a right triangle.
we can write:
tan(55 degrees) = 32 / d
To solve for "d", we can rearrange the equation:
d = 32 / tan(55 degrees)
Using a calculator, we can evaluate the tangent of 55 degrees:
tan(55 degrees) = 1.428
d = 22.4 meters
Therefore, the car is approximately 22.4 meters away from the tower.

We have a circular plate of radius a
. The temperature distribution, u(rho,ϕ)
, has boundary conditions u(a,ϕ)=T1
when 0<ϕ<π
and T2
when π<ϕ<2π
. The steady state temperature distribution satisfies the Laplace equation.
I have used separation of variables to reduce the equation to two ODE's which I solved to find the general solution to be u(rho,ϕ)=∑Cλexp(λϕ)ϕλ
The question then asks us to find the Fourier series for u(a,ϕ)
. I did this by finding the series for the two boundary conditions which resulted in: u(a,ϕ)=(T1−T2)2+∑((−1m)−1)(T2−T1)sin(mϕ)πm
(Noted that I am not 100% sure this is correct)
The final part of the question, and the source of my problem, asks us to find an expression for u(rho,ϕ)
as an infinite series using the previous answer. I do not understand how to form a general solution using this - I cannot see how the Fourier series is of any relevance to a general solution as it doesnt appear to help us find Cλ
or λ
itself. Any help would be much appreciated!
Answers
the Fourier series solution is not directly used to find the general solution but is used as a part of it, along with the radial solution. The Fourier series solution helps in finding the solution to the given boundary value problem, which, when combined with the radial solution, gives the complete solution to the Laplace equation.
The Fourier series approach that you have used helps in finding the solution to the boundary value problem, i.e., finding u(a,ϕ) for the given boundary conditions. However, to find a general solution to the Laplace equation, we need to use the superposition principle, which states that the sum of any two solutions to the Laplace equation is also a solution.
Therefore, we can use the previously obtained Fourier series solution for u(a,ϕ) as a building block to construct the general solution. We know that the Laplace equation has radial symmetry, which means that the temperature distribution is only a function of radius (rho) and not of angle (ϕ). Hence, we can write the general solution as:
u(rho,ϕ) = f(rho) + u(a,ϕ)
where f(rho) is the radial component of the solution and u(a,ϕ) is the previously obtained Fourier series solution.
To find f(rho), we need to solve the radial ODE using the boundary conditions at rho=0 and rho=a. Once we have obtained f(rho), we can add it to u(a,ϕ) to get the general solution.
Therefore, the Fourier series solution is not directly used to find the general solution but is used as a part of it, along with the radial solution. The Fourier series solution helps in finding the solution to the given boundary value problem, which, when combined with the radial solution, gives the complete solution to the Laplace equation.

Put the quadratic into vertex form and state the coordinates of the vertex.
y = x2 – 10x + 9
What is the vertex form?
Answers
Answer: y=(x-5)^2-16
Answer:
Step-by-step explanation:
First, we need to use the formula -b/2a.
We get 10/2 which equals 5.
Now we have our x-coordinate. Now we need to find out y-coordinate. We have to plug 5 back in as x to get the y-variable.
5^2 - 10(5) + 9
25 - 50 + 9
34 - 50
-16
Now that we have our x and y coordinates, we can make our vertex.
(5,-16)
Finally, we need to put this into vertex form. We see that the vertex form is y = a(x-h)^2 + k. We plug the x variable into the h value and the y variable into the k value. We don't need the a variable because we are only looking for the vertex and the vertex form.
y = (x-5)^2 - 16

We have,
x = cost of a donut
y = cost of donut holes
Cleo:

48y + 36x = 20 ________(2)

From (1) and (2),
Multiplying 2 on (1).

Substituting x = 1/2

24y + 24 = 25
