1a. Solve the differential equations
y" + 5y' + 6y = 0, y(0) = 1 and y'(0) = 2
Note that each equation has right hand side zero. So, you don’t have to use the Laplace transform. You just use the characteristic equaiton.
Answers
y'' + 5y' + 6y = 0
has characteristic equation
r² + 5r + 6 = (r + 2) (r + 3) = 0
with roots at r = -2 and r = -3, hence the differential equation's characteristic solution is
[tex]y(t) = C_1 e^{-2t} + C_2 e^{-3t}[/tex]
Given that y(0) = 1 and y'(0) = 2, we have
[tex]y(t) = C_1 e^{-2t} + C_2 e^{-3t} \implies 1 = C_1 + C_2[/tex]
[tex]y'(t) = -2C_1 e^{-2t} - 3C_2 e^{-3t} \implies 2 = -2C_1 - 3C_2[/tex]
and solving the resulting system of equations yields C₁ = 5 and C₂ = -4.
So the particular solution to the ODE is
[tex]\boxed{y(t) = 5 e^{-2t} - 4 e^{-3t}}[/tex]

When f(x) is a differentiable function
satisfying [tex]\lim_{x \to \\\pi } \frac{f(x)}{x-\pi}[/tex]
Find [tex]\lim_{x \to \\\pi } \frac{sin(2f(x))}{x-\pi}[/tex]
Answers
Presumably, the first limit is some finite number
[tex]\displaystyle \lim_{x\to\pi} \frac{f(x)}{x-\pi} = c[/tex]
Since x - π clearly approaches 0 as x approaches π, we must also have f(x) approaching 0,
[tex]\displaystyle \lim_{x\to\pi} f(x) = 0[/tex]
Recall the double angle identity,
sin(2t) = 2 sin(t) cos(t)
and rewrite the limit as
[tex]\displaystyle \lim_{x\to\pi} \frac{\sin(2 f(x))}{x - \pi} = \lim_{x\to\pi} \frac{2 \sin(f(x)) \cos(f(x))}{x - \pi} = 2 \lim_{x\to\pi} \frac{\sin(f(x))}{f(x)} \times \frac{f(x) \cos(f(x))}{x - \pi}[/tex]
Recall that
[tex]\displaystyle \lim_{x\to0}\frac{\sin(x)}x=1[/tex]
which means
[tex]\displaystyle \lim_{x\to\pi}\frac{\sin(f(x))}{f(x)} = \lim_{f(x)\to0}\frac{\sin(f(x))}{f(x)} = 1[/tex]
and by continuity,
[tex]\displaystyle \lim_{x\to\pi} \cos(f(x)) = \cos\left(\lim_{x\to\pi} f(x)\right) = \cos(0) = 1[/tex]
Then
[tex]\displaystyle 2 \lim_{x\to\pi} \frac{\sin(f(x))}{f(x)} \times \frac{f(x) \cos(f(x))}{x - \pi} \\\\ = 2 \left(\lim_{x\to\pi}\frac{\sin(f(x))}{f(x)}\right) \left(\lim_{x\to\pi} \frac{f(x)}{x-\pi}\right) \left(\lim_{x\to\pi}\cos(f(x))\right) \\\\ = 2 \times 1 \times c \times 1 = \boxed{2c}[/tex]

Anna, Betty and Candy shared a box of sweets. Anna took 8 more than 1/3 of the number of sweets in the box. Betty took 18 more than half of the remaining number of sweets . If Candy took the last 6 sweets, how many sweets were there in the box at first?
Answers
Answer: 108
Step-by-step explanation: Let the total number of sweets be x
Therefore, Anna - (x/3)+8
After Anna, remaining amount is x - ((x/3)+8) = 2x/3 + 8
Betty took (2x/3 + 8)/2 + 18 = x/3 + 22
Remaining = x - ((x/3)+8) - (x/3 + 22) = x/3 -30
Candy took the rest which is 6 i.e.
x/3 - 30 = 6
x/3 = 36
x = 108
In this figure, 52.9% of the area is painted yellow. How much of the area is painted yellow? 22.218 in² 25.921 in² 44.436 in² 48.139 in² A square with sides measuring 7 inches. A right triangle attached to one side of the square has a long leg of 12 inches.
Answers
Answer:
the answer is 48.139 in²
Step-by-step explanation:
I took the test.
48.139 in² of the figure area is painted yellow in color.
What is an area?An area is amount of space occupied by a two dimensional shape or object.
The area of the figure = Area of the square + Area of the triangle
Area of the figure = (7 in * 7 in) + (1/2) * (12 * 7) = 91 in²
Since 52.9% of the area is painted yellow, hence:
Area painted yellow = 52.9% of 91 = 48.139 in²
48.139 in² of the figure area is painted yellow in color.

The values of x at wich F(x) has local minimums are x = -2 and x = 4, and the local minimums are:
F(-2) = -3F(4) = -5What is a local maximum/minimum?
A local maximum is a point on the graph of the function, such that in a close vicinity it is the maximum value there. So, on an interval (a, b) a local maximum would be F(c) such that:
c ∈ (a, b)
F(c) ≥ F(x) for ∀ x ∈ [a, b]
A local minimum is kinda the same, but it must meet the condition:
c ∈ (a, b)
F(c) ≤ F(x) for ∀ x ∈ [a, b]
A) We can see two local minimums, we need to identify at which values of x do they happen.
The first local minimum happens at x = -2
The second local minimum happens at x = 4.
B) The local minimums are given by F(-2) and F(4), in this case, the local minimums are:

For a certain company, the cost for producing x items is 60x+300 and the revenue for selling x items is 100x−0.5x2.
The profit that the company makes is how much it takes in (revenue) minus how much it spends (cost). In economic models, one typically assumes that a company wants to maximize its profit, or at least wants to make a profit!
Part a: Set up an expression for the profit from producing and selling x items. We assume that the company sells all of the items that it produces. (Hint: it is a quadratic polynomial.)
Part b: Find two values of x that will create a profit of $50 .
Answers
The profit function of the company is the difference between the cost and the revenue functions of the company
The expression of the profit function is [tex]- 0.5x^2 + 40x - 300[/tex]The two values of x that creates a profit of $50 are x = 10 and x = 70How to set up the profit functionThe given parameters are:
C(x) = 60x + 300 --- the cost function
R(x) = 100x - 0.5x^2 ---- the revenue function
The profit function is calculated as:
P(x) = R(x) - C(x)
So, we have:
[tex]P(x) = 100x - 0.5x^2 - 60x - 300[/tex]
Rewrite as:
[tex]P(x) = - 0.5x^2 + 100x - 60x - 300[/tex]
[tex]P(x) = - 0.5x^2 + 40x - 300[/tex]
This means that the expression of the profit function is [tex]- 0.5x^2 + 40x - 300[/tex]
The two values of x that creates a profit of $50This means that:
P(x) = 50
So, we have:
[tex]- 0.5x^2 + 40x - 300 = 50[/tex]
Subtract 50 from both sides
[tex]- 0.5x^2 + 40x - 350 = 0[/tex]
Multiply through by -2
[tex]x^2 - 80x + 700 = 0[/tex]
Expand
[tex]x^2 - 70x - 10x + 700 = 0[/tex]
Factorize
[tex]x(x - 70) - 10(x - 70) = 0[/tex]
Factor out x - 70
[tex](x - 10)(x - 70) = 0[/tex]
Solve for x
x = 10 or x = 70
Hence, the two values of x that creates a profit of $50 are x = 10 and x = 70
