Give the parametric form of the circle x² + y² = 25
x(t) =
y(t) =
This is an exercise in parametric equations, which are a way of representing a curve or surface on the plane or in space using arbitrary values or a constant called a parameter instead of using an independent variable. In the case of circles, the points (x,y) can be expressed from a single variable θ, which is called a parameter. The parametric equations of a circle with radius r ≥ 0 and center (h,k) are given by x = h + rcosθ y = k + rsinθ, where 0 < θ < 2π. The parametric equation of a circle can be expressed from the angle θ of the point through the circle with respect to the x-coordinate axis. The parametric equations of the conics, including the circumference, can be deparameterized to obtain the canonical equation.
The parametric equation of a circle can be expressed from the angle θ of the point through the circle with respect to the x-coordinate axis. The angle can be expressed in radians (θ∈[0,2π]) or sexagesimal degrees (θ∈[0º,360º]). The parametric equation of a circle with center C=(-1,3) and radius r=2 cm is defined by x = -1 + 2cosθ and y = 3 + 2sinθ.
The parametric equations of a curve are expressed from the variable (or parameter) t, such that x = x(t) and y = y(t). Each value of t determines a point (x,y) in the plane. The parametric equations of a circle with radius r ≥ 0 and center (h,k) are given by x = h + rcosθ y = k + rsinθ, where 0 < θ < 2π. The parametric equation of a circle centered at the origin and with radius r is x² + y² = r².
The parametric equations for a curve are not unique. They represent the same circle with center at (0,0) and radius R. The parametric equations of the conics, including the circumference, can be deparameterized to obtain the canonical equation. To go from the parametric to the Cartesian equations, the parameter t must be eliminated. The parametric equations of a point on a circle of radius r at an angle θ are x = rcos(θ) and y = rsin(θ).
To get this parametric form of x² + y² = 25, we can use the trigonometric identities:cos²(t) + sin²(t) = 1
Multiplying both sides by 25, we get:
25 cos²(t) + 25 sin²(t) = 25
Which is equivalent to:
x² + y² = 25
Therefore, we can write:
x(t) = 5 cos(t), y(t) = 5 sin(t)
The parametric form of the circle x² + y² = 25 is:x(t) = 5 cos(t)y(t) = 5 sin(t)This means that for every value of t in the interval 0≤t≤2π, we can get a point on the circle.

Answer:
y = -1.5x + 3
Step-by-step explanation:
gradient = (-3 - 0) / (4 - 2) = -3/2 = -1.5.
equation on line through two points is given by
y - y1 = m (x - x1)
where y1 and x1 are the coordinates of the point and m is the gradient.
we can choose either point to use in the equation.
y - 0 = -1.5 (x - 2) = -1.5x + 3
y = -1.5x + 3
Qasim spots an airplane on radar that is currently approaching in a straight line, and that will fly directly overhead. The plane maintains a constant altitude of 7200 feet. Qasim initially measures an angle of elevation of 16 ∘ ∘ to the plane at point � A. At some later time, he measures an angle of elevation of 38 ∘ ∘ to the plane at point � B. Find the distance the plane traveled from point � A to point � B. Round your answer to the nearest foot if necessary.
The plane traveled approximately 15,806 feet from point A to point B.
How to solve for the distancetan(angle) = opposite side / adjacent side
Let x be the horizontal distance from Qasim to point A and y be the horizontal distance from Qasim to point B. Then:
tan(16°) = 7200 / x
tan(38°) = 7200 / y
We can solve for x and y:
x = 7200 / tan(16°)
y = 7200 / tan(38°)
Now, we can calculate x and y:
x ≈ 7200 / 0.2878
= 25016.6 feet
y = 7200 / 0.7813
= 9210.7 feet
Finally, to find the distance the plane traveled from point A to point B, we take the difference between y and x:
distance = y - x
= 9210.7 - 25016.6
= -15805.9 feet
we take the absolute value:
distance = 15806 feet (rounded to the nearest foot)

The chances that, at least, one of the dinosaur toys in Franklin's set is a T.rex is 57%.
Probability calculationWe can use the complement rule to find the probability that none of the dinosaur toys in Franklin's set is a T. rex, and then subtract this from 1 to get the probability that at least one of the toys is a T. rex.
The probability that a given toy is not a T. rex is 90%, or 0.9.
Since there are 8 toys in the set, the probability that none of them are T. rex is:
0.9 x 0.9 x 0.9 x 0.9 x 0.9 x 0.9 x 0.9 x 0.9 = 0.43
So the probability that at least one of the toys is a T. rex is:

Find the x-coordinate of the inflection points for the function
guys pls help
After considering the given data we conclude that the x-coordinate of the inflection points for the function are x = - 2 and x = 2, which is option A.
To evaluate the x-coordinate of the inflection points for the function f(x) = ln(x² + 4) we need to evaluate the second derivative of the function and find for x when the second derivative equals zero.
The first derivative of f(x) is:
f' * (x) = (2x)/(x² + 4)
The second derivative of f(x) is:
f"(x) = 2(x² + 4)-4x² /(x²+4)² = 8 - 2x²/(x²+4)²
To evaluate the inflection points, we need to find the equation f'' (x) = 0 for x:
8 - 2x²/(x²+4)² = 0
After applying simplification this equation, we get:
8 - 2x² = 0
Evaluating for x, we get:
x = +/- √4) = +/- 2
Therefore, the x-coordinate of the inflection points for the function f(x) = ln(x² + 4)
x = - 2 and x = 2 .

A university class has 27 students: 13 are history majors, 8 are accounting majors, and 6 are art majors. (Each student has only one of these majors.) The professor is planning to select two of the students for a demonstration. The first student will be selected at random, and then the second student will be selected at random from the remaining students. What is the probability that the first student selected is an accounting major and the second student is an art major?
Answer:
8/27
Step-by-step explanation:
There are a total of 27 students in the class, and 8 of them are accounting majors. Therefore, the probability of the first student selected being an accounting major is 8/27.
After the first student is selected, there will be 26 students remaining, out of which 6 are art majors. Therefore, the probability of the second student selected being an art major, given that the first student was an accounting major, is 6/26.
To find the probability of both events occurring together, we need to multiply the individual probabilities:
P(accounting major first) * P(art major second | accounting major first)
= (8/27) * (6/26)
= 48/702

A rectangular pyramid has a base that is 14 yards long and 14 yards wide. The pyramid's slant height is 12 yards. What is its surface area?
The surface area of the rectangular pyramid is approximately 387.6 square yards.
To find the surface area of a rectangular pyramid, we need to find the area of the base and the area of the four triangular faces.
The area of the base is:
Area of base = length x width
Area of base = 14 yards x 14 yards
Area of base = 196 square yards
To find the area of the four triangular faces, we need to first find the height of each triangle using the Pythagorean theorem.
The Pythagorean theorem states that in a right triangle, the sum of the squares of the legs (the two shorter sides) is equal to the square of the hypotenuse (the longest side).
In this case, the hypotenuse is the slant height of the pyramid, which is 12 yards. The legs are half the length and width of the base, which are both 7 yards.
So we have:
h² + 7² = 12²
h² + 49 = 144
h² = 95
h = √95
Now we can find the area of each triangular face using the formula:
Area of triangle = 1/2 x base x height
The base of each triangle is 14 yards, and the height is √95 yards. So we have:
Area of triangle = 1/2 x 14 yards x √95 yards
Area of triangle = 7√95 square yards
There are four triangular faces, so the total area of the four triangular faces is:
Total area of triangular faces = 4 x 7√95 square yards
Total area of triangular faces = 28√95 square yards
Finally, we can find the total surface area by adding the area of the base and the area of the four triangular faces:
Total surface area = Area of base + Total area of triangular faces
Total surface area = 196 square yards + 28√95 square yards
Total surface area ≈ 387.6 square yards (rounded to one decimal place)

Can you help me with this question please?
A. The initial size of the culture is 222.11
B. The doubling period is approximately 13.53 minutes.
C. The population after 100 minutes is 5807.76
D . The population will reach 13000 after approximately 44.59 minutes.
How did we get these values?Use the formula for exponential growth:
N = N0 × eʳᵗ
where N is the population size at time t, N0 is the initial population size, r is the growth rate, and t is the time elapsed.
Using the given data:
At t=10, N=500
500 = N0 × eʳ×¹⁰
At t=30, N=1500
1500 = N0 × eʳ׳⁰
To solve for N0 and r, we can divide the second equation by the first:
¹⁵⁰⁰/₅₀₀ = eʳ׳⁰ / eʳ×¹⁰
3 = eʳ× ²⁰
Taking the natural logarithm of both sides:
ln(3) = r × 20
r = ln³/₂₀
r ≈ 0.0513 (rounded to 4 decimal places)
Now we can use N = N0 × eʳᵗ to answer the remaining questions:
- The initial size of the culture is:
N0 = N / eʳᵗ = 500 / ₑ(0.0513×10) ≈ 222.11 (rounded to 2 decimal places)
- The doubling period is the time it takes for the population to double. Find this by setting N = 2N0 and solving for t:
2N0 = N0 × eʳᵗ
2 = eʳᵗ
ln(2) = rt
t = ln²/ᵣ
t ≈ 13.53 (rounded to 2 decimal places)
So the doubling period is approximately 13.53 minutes.
- The population after 100 minutes is:
N = N0 × eʳᵗ = 222.11 × ₑ(0.0513×100) ≈ 5807.76 (rounded to 2 decimal places)
- To find when the population reaches 13000, we can solve N = 13000 for t:
13000 = N0 × eʳᵗ
13000 = 222.11 × ₑ(0.0513t)
58.56 = ₑ(0.0513t)
ln(58.56) = 0.0513t
t ≈ 44.59 (rounded to 2 decimal places)
So the population will reach 13000 after approximately 44.59 minutes.

Find the surface area of
the prism.
The surface area isin.²
8 in.
15 in.
5 in.
Answer: A = 470 in²
Step-by-step explanation:
If the given prism is a rectangular prism, we can use the given formula to solve for the surface area of a rectangular prism.
A = 2((8 in)(15 in) + (5 in)(15 in) + (5 in)(8 in))
A = 2(120 in² + 75 in² + 40 in²)
A = 2(235 in²)
A = 470 in²

help please which one of this is and what is the x and y
The value x, y and z from the given matrix are -3.65, -4.5 and 2.2 respectively.
From the given matrix,
[tex]\left[\begin{array}{ccc}-2&6&-7\\2&-7&-3\\6&-4&-6\end{array}\right] \left[\begin{array}{ccc}x\\y\\z\end{array}\right] =\left[\begin{array}{ccc}-47\\22\\-10\end{array}\right][/tex]
[tex]\left[\begin{array}{ccc}-2x+6y-7z\\2x-7y-z\\6x-4y-6z\end{array}\right] =\left[\begin{array}{ccc}-47\\22\\-10\end{array}\right][/tex]
-2x+6y-7z=-47 -------(i)
2x-7y-z=22 ---------(ii)
6x-4y-6z=-10 ---------(iii)
Add equation (i) and (ii), we get
-2x+6y-7z+2x-7y-z=-47+22
-y-8z=-27 ---------(iv)
Multiply equation (ii) by 3, we get
6x-21y-3z=66 ---------(v)
Subtract equation (iii) from (v), we get
6x-21y-3z-(6x-4y-6z)=66-(-10)
6x-21y-3z-6x+4y+6z=76
-17y+3z=76 ---------(vi)
Multiply equation (iv) by 17, we get
-17y-136z=-216 ---------(vii)
Subtract equation (vi) from (vii), we get
-17y-136z-(-17y+3z)=-216-76
-133z=-292
z=-292/(-133)
z=2.2
Substitute z=2.2 in equation (vii), we get
-17y-136(2.2)=-216
-17y-292.6=-216
-17y=-216+292.6
-17y=76.6
y=-4.5
Substitute y=-4.5 and z=2.2 in equation (ii), we get
2x-7y-z=22
2x-7(-4.5)-2.2=22
2x+31.5-2.2=22
2x+29.3=22
2x=22-29.3
2x=-7.3
x= -7.3/2
x= -3.65
Therefore, the value x, y and z from the given matrix are -3.65, -4.5 and 2.2 respectively.

Snow-House sells a $1,248 snow thrower on the installment plan. The installment agreement includes a 20% down payment and 12 monthly payments of $116 each. What is the total cost of the snow thrower on the installment plan?
The total cost of the snow thrower on the installment plan is $1,641.60.
To find the total cost of the snow thrower on the installment plan, we will first calculate the down payment and then add the total monthly payments. Here's the step-by-step explanation:
1. Calculate the down payment:
Down payment = 20% of the original price
Down payment = 0.20 * $1,248
Down payment = $249.60
2. Calculate the total of the 12 monthly payments:
Total monthly payments = 12 * $116
Total monthly payments = $1,392
3. Calculate the total cost on the installment plan:
Total cost = Down payment + Total monthly payments
Total cost = $249.60 + $1,392
Total cost = $1,641.60
So, the total cost of the snow thrower on the installment plan is $1,641.60.

What influenced Denis to write the first non-objective statement? (You must use one quote from his article the Definition of Neotraditionism)
What factors led Kandinsky to arrive at non-objective painting? (You must give at least one quote from Concerning the Spiritual in Art, and list the page number.
What did Kandinsky write about color? (You must give at least one quote from Concerning the Spiritual in Art - Part II. About Painting, VI: The Language of Form and Color and give the page number.)
Denis was told to write the first non-objective statement by the arising trend of Neotraditionism.
As he explains in his composition" The description of Neotraditionism,"" The thing of Neotraditionism is to make commodity new that isn't a dupe, nor a simple extension, nor a parody of the old"( Denis, 1911). He believed that this movement needed a new language of art, one that wasn't tied to emblematic forms.
Kandinsky's appearance atnon-objective oil was told by his spiritual beliefs and his desire to express the inner nature of effects. As he writes in Concerning the Spiritual in Art," The artist must have commodity to say, for mastery over form isn't his thing but rather the adapting of form to its inner meaning"( Kandinsky, 1977,p. 10). He believed that art should be a spiritual expression and that the inner world of the artist should be restated into visual language.
Kandinsky wrote considerably about color in Concerning the Spiritual in Art. He believed that color had its own language and could convey feelings and ideas. As he writes," Color is a means of plying direct influence upon the soul. Color is the keyboard. The eye is the hammer. The soul is the piano, with its numerous strings"( Kandinsky, 1977,p. 43). He believed that colors could be arranged in a way that would produce a symphony of feelings in the bystander.
