Write the equations of these circles.
a) Centre origin, radius 3/2
b) Centre origin, radius 0.5
c) Centre origin, radius root 3
The equation for the circle is x² + y² = 9/4 if the Centre origin, radius 3/2, and for the Centre origin, radius 0.5 is x² + y² = 0.25.
What is a circle?It is described as a set of points, where each point is at the same distance from a fixed point (called the center of a circle).
It is given that:
The center of the circle is (0, 0) or the origin.
The radius of the circles is given.
As we know, the standard equation for the circle is:
(x - h)² + (y - k)² = r²
Here (h, k) is the center and r is the radius of the circle.
a) Centre origin, radius 3/2
Plug h = 0, k = 0, and r = 3/2
x² + y² = (3/2)²
x² + y² = 9/4
Similarly,
b) Centre origin, radius 0.5
x² + y² = 0.25
c) Centre origin, radius √3
x² + y² = 3
Thus, the equation for the circle is x² + y² = 9/4 if the Centre origin, radius 3/2, and for the Centre origin, radius 0.5 is x² + y² = 0.25.

How do I do 2 and 3
Answer:
y=52
x=46
questions 3
x=84
y=84
Step-by-step explanation:
Answer:
#2: x = 64 y = 32[tex]\sqrt{3}[/tex]
#3: x = 6[tex]\sqrt{2}[/tex] y = 6[tex]\sqrt{2}[/tex]
Or, if you are supposed to write your answers in decimal form instead:
#2: x = 64 y = 55.43
#3: x = 8.49 y = 8.49
Step-by-step explanation:
Special right triangles have specific angle measurements that tell you the lengths of each side. I attached an image that explains the rules of different special right triangles in case you need it :)
#2 is a 30-60-90 triangle. This means that x (the side opposite the 90° angle) is two times the length of the shortest side (32×2), and y is equal to 32[tex]\sqrt{3}[/tex].
#3 is a 45-45-90 triangle. This means that x (the side opposite the 45° angle) is equal to y (the side opposite the other 45° angle). The hypotenuse, 12, is x[tex]\sqrt{2}[/tex] (or y[tex]\sqrt{2}[/tex], since x = y). This means 12 = x[tex]\sqrt{2}[/tex]

If y= cx" and dy/dx =
4/root x
what are the values of c and n?
Answer:
c = 8
n = 1/2
Step-by-step explanation:
Since dy/dx is the derivative form, we can integrate the answer to get the value of y.
The values of c and n are obtained by forming the equations as 1/2 and 8 respectively.
What is differentiation?The differentiation of a function is defined as rate of change of its value at a point. It can be written as f'(x) = (f(x + h) - f(x)) /(x + h - x).
It can be stated in terms of geometry as the slope of tangent of the function at a given point.
It is given as y = cxⁿ and dy/dx = 4/√x.
Take the derivative of y = cxⁿ with respect to x as,
dy/dx = cd(xⁿ)/dx
⇒ nc × xⁿ⁻¹
Compare the obtained derivative with 4/√x to obtain,
nc = 4 and n - 1 = -1/2
⇒ n = 1/2 and c = 8
Hence, the values of c and n are 1/2 and 8 respectively.

The Groves basketball team did not record how many baskets were made by each player during the last game. Daniel remembers that he made three times as many baskets as Ben. Max knows that he made six more baskets than Ben. Mitchell is sure that he made fewer baskets than Ben. Christion is sure that he made the same number of baskets as Mitchell. Altogether the five players made 40 baskets. How many baskets did each player make?
Answers:
Ben = 6Max = 12Mitchell = 2Christion = 2Daniel = 18Each count above refers to the number of baskets made for the given player.
====================================================
Explanation:
For each player, let the following variables represent how many baskets were made
B = BenM = MaxT = MitchelC = ChristionD = DanielSo for example, if D = 10, then this means Daniel made 10 baskets. Though for now, we're not sure what number replaces D or any given letter.
------------------
"Daniel remembers that he made three times as many baskets as Ben" tells us that D = 3B is one equation
We know another equation is M = B+6 since Max made six more baskets than Ben
Another equation is C = T because these two students (Christion and Mitchell) made the same number of baskets.
We also know that T < B since Mitchell made fewer baskets compared to Ben.
Altogether the boys made 40 baskets total, so B+M+T+C+D = 40
-------------------
We have these five mathematical statements
D = 3BM = B+6C = TT < BB+M+T+C+D = 40Let's focus on the last equation
B+M+T+C+D = 40
B+M+T+C+3B = 40 .... plug in D = 3B
4B+M+T+C = 40
4B+M+T+T = 40 .... plug in C = T
4B+M+2T = 40
4B+B+6+2T = 40 .... plug in M = B+6
5B+6+2T = 40
5B+2T = 40-6
5B+2T = 34
Now let's solve for T
5B+2T = 34
2T = 34-5B
2T = -5B+34
T = (-5B+34)/2
T = (-5B)/2 + 34/2
T = -2.5B + 17
----------------------------------
We've eliminated everything but two variables at this point.
Let's say that x replaced B and y replaces T
We get the equation y = -2.5x + 17
If you graph this equation along with y = x, you'll find that the two equations intersect at roughly (4.857, 4.857)
Since we want T < B, this means we want y < x to be the case. The line y = -2.5x+17 goes downhill as we move from left to right. If x is smaller than 4.857, then x >= y. Otherwise, if x is larger than 4.857, then y < x
Furthermore, looking at a table of values for this equation shows that only (x,y) = (6,2) is a point on y = -2.5x+17 such that both x and y are positive and x is the larger value, and they are both integer coordinates.
All of this means that when B = 6, this pairs with T = 2. No other number pair is possible for these two students.
We then use this to find the other player's basket count
D = 3B = 3*6 = 18M = B+6 = 6+6 = 12C = T = 2----------------------------------
So we have the following results
B = 6M = 12T = 2C = 2D = 18As a check,
B+M+T+C+D = 6+12+2+2+18 = 40
which confirms our answers.

Answer:
Ben: 6Daniel: 18Max: 12Mitchell: 2Christion: 2Step-by-step explanation:
Let x and y represent baskets made by Ben and Mitchell, respectively. Then Daniel made 3x baskets, Max made (x+6) baskets, and Christion made y baskets. The total number is ...
x + 3x +(x+6) +y +y = 40
5x +2y = 34 . . . . . . . . . . . subtract 6
The other constraint on the solution is ...
y < x . . . . . . . . . Mitchell made fewer baskets than Ben
__
We can see that 34 differs from a multiple of 5 by an even number, so (by inspection) we determine that (x, y) = (6, 2) is a solution to the equation. (It is also a solution to the inequality.)
Other possible solutions will require y increase by 5 as x decreases by 2, so those are ...
(x, y) = {(6, 2), (4, 7), (2, 12), (0, 17)}
The only (x, y) pair that satisfies the inequality is the first one: (x, y) = (6, 2). Hence the numbers of baskets are ...
Ben: 6Daniel: 18Max: 12Mitchell: 2Christion: 2

Three small shipping boxes and one large shipping box hold 64 pounds. A large shipping box minus a small shipping
box holds 32 pounds. When writing a system of equations to determine how many pounds each small box (x) and each
large box (y) holds, which statements are true?
A)
y + 3x = 64
y - x = 32
B)
y - 3x = 64
y + x = 32
3y - x = 64
y - x = 32
D)
(8. 40) is the solution to the system.
E)
(12, 10) is the solution to the system.
Answer:
y + 3x = 64
y - 3x = 32
(8,40) is the solution to the system
(Basically A & D)
Step-by-step explanation:
1 large + 3 small = 64 y+3x=64
1 large - 1 small = 32 y-x=32
(12,10) cannot be a solution because the small box (x) holds more than the large box (y).
Substitute (8,40): 40 + 3(8) = 64 and 40 - 8 =32
