Answer:r=3cscθ
Step-by-step explanation:The equation y = 3 represents a horizontal line at a distance of 3 units above the x-axis in the Cartesian coordinate system. To convert this equation into polar form, we can use the fact that x = rcos(theta) and y = rsin(theta) in polar coordinates.
Since y = 3 for all values of x, we can say that r*sin(theta) = 3. Solving for r, we get:
r = 3/sin(theta)
This equation represents a family of circles with center at the origin and radius 3/sin(theta), for all values of theta except for multiples of pi. We can simplify this equation by using the identity sin(theta) = 1/csc(theta), giving us:
r = 3csc(theta)

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
360° - (43(3) - 3)° = 360° - 126° = 234°.
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.

Answer:
254.3 ft^2
Step-by-step explanation:
First, let’s find the area of the entire circle. The area for a circle is 3.14 * radius^2
3.14*18^2 = 1017.36
Now, notice how the angle marked is 90 degrees, that means that this section of the circle is 90/360 (360 is the angle of a circle), or 1/4 of a whole circle. Now we can multiply 1/4 by the area to find 1/4 of the whole circle.
1017.36*1/4 = 254.34

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

The length of the hypotenuse of the given right angled triangle is √113.
Three given side lengths of a triangle a, b and c are said to be the sides of the right angled triangle if -
a² = b² + c²
The above theorem is known as the Pythagoras theorem.
Now, we can write that -
(hypotenuse)² = (base)² + (perpendicular)²
(hypotenuse)² = (7 x 7) + (8 x 8)
(hypotenuse)² = 49 + 64
(hypotenuse)² = 113
(hypotenuse) = √113
So, the length of the hypotenuse of the given right angled triangle is √113.

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.

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)

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.
