Solve the following differential equations:
The solution of the differential equation is y + e²ˣ = Ceˣ, if Ceˣ > 0
or -y - e²ˣ = Ceˣ, if Ceˣ < 0.
What is the solution of the differential equation?The solution of the differential equation is calculated as follows;
dy/dx = e²ˣ + y
Apply the method of separating viables;
dy/dx = e²ˣ + y
dy/(y + e²ˣ) = dx
Integrate both sides;
∫ dy/(y + e²ˣ) = ∫ dx
ln|y + e²ˣ| = x + C
To solve for y, we need to exponentiate both sides;
|y + e²ˣ| = e^(x+C) = Ceˣ
The final solution becomes;
y + e²ˣ = Ceˣ, if Ceˣ > 0
or
-y - e²ˣ = Ceˣ, if Ceˣ < 0

Help on 3 and 5…………..
Answer:
The measure of an inscribed angle in a circle equals half the measure of its intercepted arc.
3) 56 + 2x = (1/2)(112 + x)
x = 0, so the measure of arc BCD is
360° - 112° = 248°.
5) 3 + 20x = (1/2)(43x - 3)
6 + 40x = 43x - 3
3x = 9, so x = 3
The measure of arc MLK is

Expressing as single logarithm 3/2㏑4x⁶ - 2/5㏑2y²⁵ = ㏑(2x⁹/y¹⁰)
How to express the logarithm eqaution as a single logarithm?Since we have the logarithm expression
3/2㏑4x⁶ - 2/5㏑2y²⁵
To simplify, we proceed as follows
First, we use the power law of logarithm which states that
n㏑x = ㏑xⁿ
So, using this, we have that
3/2㏑4x⁶ - 2/5㏑2y²⁵ = ㏑4x⁶ - 2/5㏑2y²⁵
[tex]= ln4x^{6\times\frac{3}{2} } - ln2y^{25\times\frac{2}{5} } = ln4x^{3\times3} } - ln2y^{5\times2 }[/tex]
= ㏑4x⁹ - ln2y¹⁰
Using the subtraction law of logarithm, which states that
㏑a - ㏑b = ㏑(a/b), we have that
㏑4x⁹ - ln2y¹⁰ = ㏑(4x⁹/2y¹⁰)
= ㏑(2x⁹/y¹⁰)
So, 3/2㏑4x⁶ - 2/5㏑2y²⁵ = ㏑(2x⁹/y¹⁰)

12. David is building a ramp to go up the step into his
house. The step is 2 foot high. The ramp is 7.3 feet long and
the end of the ramp will be 7.0 feet from the step. What is
the slope of the ramp? Express the answer as a fraction.
(2/7.3 or 7.3/2 or 2/7 or 7/2 or 7/7.3 or 7.3/7)
Answer: The slope of the ramp is defined as the rise over the run, where the rise is the height of the step (2 feet) and the run is the horizontal distance from the bottom of the ramp to the step (7.0 feet). However, since the ramp is not straight but inclined, we need to use the length of the ramp (7.3 feet) to calculate the actual horizontal distance it covers.
Therefore, the run of the ramp is the square root of the difference between the length of the ramp squared and the height of the step squared:
run = sqrt(7.3^2 - 2^2) = sqrt(52.29 - 4) = sqrt(48.29) ≈ 6.95 feet
Now we can calculate the slope of the ramp:
slope = rise / run = 2 / 6.95 = 0.2885 ≈ 2/7
Therefore, the slope of the ramp is approximately 2/7.

College p has 32% less
The initial sum of the number of students in College P and College Q is 5040.
We have,
Let's assume that the number of students in college Q is represented by Q, and the number of students in college P is represented by P:
P = Q - 0.32Q = 0.68Q
We also know that if 960 more students enroll in college P, the two colleges will have the same number of students.
So, we can set up another equation:
P + 960 = Q
We can substitute the first equation into the second equation to eliminate P:
0.68Q + 960 = Q
Solving for Q, we get:
0.32Q = 960
Q = 3000
The initial number of students in college Q was 3000.
We can use this value to find the initial number of students in college P:
P = 0.68Q = 0.68(3000) = 2040
So, the initial sum of the number of students in College P and College Q is:
P + Q = 2040 + 3000 = 5040
Therefore,
The initial sum of the number of students in College P and College Q is 5040.

Your question is incomplete but most probably your full question was,
A restaurant offers a $12 dinner special that has 5 choices for an appetizer, 13 choices for an entrée, and 4 choices for a dessert. How many different meals are available when you seject an appetizer, an entrée, and a dessert?
To calculate the number of different meals available when selecting an appetizer, an entrée, and a dessert, we need to multiply the number of choices for each course.
Using the multiplication principle of counting, we can find the total number of meal options as follows:
Total number of meal options = number of appetizer choices x number of entrée choices x number of dessert choices
Total number of meal options = 5 x 13 x 4
Total number of meal options = 260
Therefore, there are 260 different meals available when you select an appetizer, an entrée, and a dessert from the given choices.
Which of the following combinations of side lengths would NOT form a triangle with vertices X, Y, and Z?
OA. XY = 15 mm, YZ 10 mm, X
,
OB. XY = 18 mm, YZ = 10 mm, XZ = 25 mm
XY = 18 mm, Z= = 13 mm, XZ = 22 mm
XY 15 mm, YZ = 10 mm, XZ = 22 mm
C.
OD.
XZ = 28 mm
The combinations of side lengths that would not form a triangle with vertices X, Y, and Z is A. XY = 15 mm, YZ = 10 mm, and XZ = 28 mm.
How can we determine combinations of side lengths that would not form a triangle?We shall us the triangle inequality theory for this problem.
According to this theory, the addition of the lengths of any two sides of a triangle must be greater than the length of the third side.
Therefore, for the sides XY, YZ, and XZ to form a triangle, we must have:
XY + YZ > XZ
YZ + XZ > XY
XZ + XY > YZ
We can check each option to see if it satisfies these conditions:
A. XY = 15 mm, YZ = 10 mm, XZ = 28 mm
15 + 10 > 28 (not satisfied)
10 + 28 > 15 (satisfied)
28 + 15 > 10 (satisfied)
Option A does not satisfy the condition XY + YZ > XZ, so it would not form a triangle.
B. XY = 18 mm, YZ = 10 mm, XZ = 25 mm
18 + 10 > 25 (satisfied)
10 + 25 > 18 (satisfied)
25 + 18 > 10 (satisfied)
Option B satisfies all the conditions, so it would form a triangle.
C. XY = 18 mm, YZ = 13 mm, XZ = 22 mm
18 + 13 > 22 (satisfied)
13 + 22 > 18 (satisfied)
22 + 18 > 13 (satisfied)
Option C satisfies all the conditions, so it would form a triangle.
D. XY = 15 mm, YZ = 10 mm, XZ = 22 mm
15 + 10 > 22 (satisfied)
10 + 22 > 15 (satisfied)
22 + 15 > 10 (satisfied)
Option D satisfies all the conditions, so it can form a triangle.
Therefore, the combinations that would not form a triangle is A, where XY = 15 mm, YZ = 10 mm, and XZ = 28 mm.

y = -0.5x - 3y = 2x/5 + 4y = 4x/5y = -1/3(x) - 1/3y = 5.How to determine an equation of this line?In Mathematics and Geometry, the point-slope form of a straight line can be calculated by using the following mathematical equation (formula):
y - y₁ = m(x - x₁)
Where:
x and y represent the data points.m represent the slope.Since the equation of this line is parallel to the line x + 2y = 4, the slope is given by;
Slope, m = -0.5
y - y₁ = m(x - x₁)
y + 3.5 = -0.5(x - 1)
y = -0.5x - 3
Since the equation of this line is perpendicular to the line 5x + 2y + 2 = 0, the slope is given by;
Slope, m = -5/2
m₁ × m₂ = -1
-5/2 × m₂ = -1
Slope, m₂ = 2/5
y - y₁ = m(x - x₁)
y - 2 = 2/5(x + 5)
y = 2x/5 + 4
Since the equation of this line passes through the origin (0, 0) and parallel to the line 4x - 5y = 10, the slope is given by;
Slope, m = 4/5
y - y₁ = m(x - x₁)
y - 0 = 4/5(x - 0)
y = 4x/5
Since the equation of this line is perpendicular to the line 3x - y = 4 and cuts the x-axis at -1, the slope is given by;
Slope, m = 3
m₁ × m₂ = -1
3 × m₂ = -1
Slope, m₂ = -1/3
y - y₁ = m(x - x₁)
y - 0 = -1/3(x + 1)
y = -1/3(x) - 1/3
Since the line is perpendicular to the y-axis and passes through the point (-3, 5), the equation is given by;
y = 5.

The volume of the prism in cubic inches is 4/9 cubic in if each cube in the prism measures 1/3 inch on one side.
Hence, the correct option is A.
If each cube in the prism measures 1/3 inch on one side, then the volume of one cube is (1/3)³ = 1/27 cubic inches.
To find the volume of the prism, we need to know how many cubes are in the prism. Let's assume the prism has dimensions of length L, width W, and height H, all measured in units of cubes. Then, the total number of cubes in the prism is L × W × H.
Therefore, the volume of the prism in cubic inches is
Volume = (L × W × H) × (1/27) cubic inches
From the given figure, we can find
L = 3 inch
W = 2 inch
H = 2 inch
