[tex]\textsf{Choice A } \quad y = \dfrac{5}{3}x + 1[/tex]
Step-by-step explanation:
Slope intercept form of a line equation is
y = mx + b
where
m = slope
b = y-intercept
A perpendicular line to y = mx + b will have a slope of -1/m
Let's first find the equation for line z in slope-intercept form
Slope m for a line = (y2- y1)/(x2 - x1) where x1, y1 and x2, y2 are two points on the line
Slope of line z is
[tex]m = \dfrac { 2 - (-1) }{-2 - 3} = \dfrac{3}{-5} = - \dfrac{3}{5}[/tex]
So line z will have an equation of the form
[tex]y = -\dfrac{3}{5}x + b[/tex]
We know that a line perpendicular to this line will have a slope of
[tex]- \dfrac{1}{-\dfrac{3}{5}} = \dfrac{5}{3}[/tex]
So the equation of the perpendicular line is
[tex]y = \dfrac{5}{3}x + b[/tex]
Only one of the 4 choices, name choice A has this slope of 5/3
Therefore the correct answer choice is A
There is no need to compute b, the y intercept but if you wanted to, this is how you would do it:
The perpendicular line passes through (3, 6). This means when x = 3, y =6
Substitute these values of x, y into the equation for the perpendicular line and solve for b
[tex]y = \dfrac{5}{3}x + b\\\\\text{When x = 3, y = 6}:\\\\6 = \dfrac{5}{3} \cdot 3 + b\\\\6 = 5 + b\\\\b = 6 - 5 = 1\\\\\text{So, the equation of the perpendicular line is }\\y = \dfrac{5}{3}x + 1[/tex]
This corresponds to Choice A

Solve the following differential equations:
Answers
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

S = a / (1 - r)
where "a" is the first term of the series and "r" is the common ratio between consecutive terms.
In this case, the first term is 3 and the common ratio is -1/3. So we can plug these values into the formula:
S = 3 / (1 - (-1/3))
S = 3 / (4/3)
S = 9/4
So the sum of the infinite series is 9/4.

College p has 32% less
Answers
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.

Answers
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.

Being Male and driving to work are independent events.

Hence, Blank 1 is 'independent event' and Blank 2 is '='.
Probability of being male is,
P(Being male) = 0.54
Probability of driving to work is,
P(Driving to work) = 0.5
Probability of being male and driving to work is,
P(Being male and driving work) = 0.27
And P(Being Male)*P(Driving to work) = 0.54*0.5 = 0.27
Since, P(Being male and driving work) = P(Being male)*P(Driving to work)
Hence, Being Male and Driving to work are independent event.
P(Drive | Male) = P(Male and Drive)/P(Male) = 0.27/0.54 = 0.5

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)

Total number of meal options = 5 x 13 x 4
Total number of meal options = 260
