Find the coordinates of a point on a circle with radius 10 corresponding to an angle of
325∘
To find the coordinates of a point on a circle with radius 10 corresponding to an angle of 325 degrees, you can use the following formula:
(x, y) = (r * cos(θ), r * sin(θ))
where (x, y) are the coordinates of the point, r is the radius of the circle, and θ is the angle in radians.
To convert the angle from degrees to radians, you can use the following formula:
θ (radians) = θ (degrees) * (π / 180)
Substituting the values into the formula and converting the angle to radians, you get:
(x, y) = (10 * cos(325 * (π / 180)), 10 * sin(325 * (π / 180)))
= (-5.5, 9.5)
Therefore, the coordinates of the point on the circle with radius 10 corresponding to an angle of 325 degrees are (-5.5, 9.5).
What are the coordinates point?
The coordinates of a point in a coordinate system are a set of numerical values that specify the position of the point in relation to an origin. In a two-dimensional coordinate system, such as the Cartesian coordinate system, a point is represented by an ordered pair (x, y), where x and y are the coordinates of the point. The x-coordinate represents the point's position along the horizontal axis, and the y-coordinate represents the point's position along the vertical axis.

9 apples and 6 oranges cost $33
18 apples and 20 oranges cost $80
How much does 1 apple and 1 orange cost
The cost of each apple and each orange will be $2.5 and $1.75, respectively. The cost of 1 apple and 1 orange will be $4.25.
The allocation of weights to the important variables that produce the calculation's optimum is referred to as a direct consequence.
9 apples and 6 oranges cost $33 and 18 apples and 20 oranges cost $80.
Let 'x' be the cost of each apple and 'y' be the cost of each orange. Then the equations are given as,
9x + 6y = 33 ...1
18x + 20y = 80 ...2
Multiply equation 1 by negative 2, then we have
-18x - 12y = - 66 ...3
Add equations 2 and 3, then we have
20y - 12y = 80 - 66
8y = 14
y = $1.75
Then the cost of each apple is calculated as,
9x + 6(1.75) = 33
9x = 33 - 7.5
9x = 22.5
x = $2.5
The cost of each apple and each orange will be $2.5 and $1.75, respectively.
The cost of 1 apple and 1 orange will be given as,

a. Identify the amount borrowed, the annual interest rate, the number of payments per year, the loan term, and the payment amount.
The amount borrow is $__, the annyual interest rate is ___%, the number of payments per year is ___, the loan term is ___ years, and the payment amount is $___.
The amount borrowed is $66,000, the annual interest rate is 4 %, the number of payments per year is 12, the loan term is 20 years, and the payment amount is $10668.39.
What is compound interest?Compound interest is applicable when there will be a change in the principle amount after the given time period.
For example, if you give anyone $500 at the rate of 10% annually then $500 is your principle amount. After 1 year the interest will be $50 and hence principle amount will become $550 now for the next year the interest will be $550, not $500.
The total amount paid is,
A = 4800[1 + 0.04/12]^(12 x 20)
A = $10668.39
Hence "The amount borrowed is $66,000, the annual interest rate is 4 %, the number of payments per year is 12, the loan term is 20 years, and the payment amount is $10668.39".

Step-by-step explanation:
Given that,
8 + (n - 4)
According to Associative Property:
A + (B + C) = (A + B) + CUsing Associative property for the given expression.
We get:
(8 + n) - 4[tex]\rule[225]{225}{2}[/tex]
The answer to this question is = 12 + n is the expression not equivalent to 8 + (n - 4)
Let us consider any random value of n for example let us take the value of n = 5
As per the original equation given in question 8 + (n - 4) if we substitute the value of n = 5
= 8+ (5 - 4)
= 8+1
= 9
Now we will be substituting the value of n in all the answer options-
Option 1- (8 - 4) + n
= (8 - 4) + 5
= 4 + 5
= 9
Therefore, this answer matches the original equation so this is not the correct option
Option 2- (8 + 4) - n
= (8 + 4) - 5
= 13 - 5
= 9
Therefore, this answer matches the original equation so this is not the correct option
Option 3- n+4
= 5 + 4
= 9
Therefore, this answer matches the original equation so this is not the correct option
Option 4- 12 + n
= 12 + 5
= 17
Therefore, this answer does not match the original equation so the correct option is = 12 + n

a circle c has center at the origin and radius 4. another circle k has a diameter with one end at the origin and the other end at the point the circles c and k intersect in two points. let p be the point of intersection of c and k which lies in the first quadrant. let be the polar coordinates of p, chosen so that is positive and find and .
Let (r,q) represent P's polar coordinates, with r being positive and 0 equaling q being pi/2. If so, r = 3m. And A = 0.20136
All points in a plane that are at a specific distance from a specific point, the center, form a circle.
Formula for the first circle: x²+ y² = 9
Formula for the second circle:
center is (0, 7.5) and the radius is 15/2, so
x² + (y - 7.5)² = (7.5)²
Combining these yields:
9 - y² + (y - 7.5)² = (7.5)²
9 - y² + y² - 15y + (7.5)² = 7.5²
9 - 15y = 0
y = 9/15 = 3/5
∴ y = 0.6
x² + y² = 9 = x² + (3/5)²
x² = 9 - (9/25)
x² = [(225 - 9)/25] = 216/25
∴ x = 2.9394
r = √(x² + y²) =
r = √[( 216/25) + (9/25)]
r = √(225/25) = 15/5
∴ r = 3
The x and y values appear to be accurate because this must be the same as the radius of the circle cantered at the origin.
sin(A) = y/r
sin(A) = (3/5)/3 = 1/5
Sin(A) = 0.2

dt = rA, A(0) = 15,000 and A(8) = $22,377.37
The amount A in an account to the nearest cent, the amount A in the account after 10 years is $30,441.65.
What is the amount A in an account?Generally, To find the amount A in the account after 10 years, we can use the formula for continuous compound interest:
A(t) = A(0) * e^(rt)
where A(t) is the amount in the account after t years, A(0) is the initial amount in the account, r is the interest rate, and t is the number of years.
In this case, we know that A(0) = $15,000, A(8) = $22,377.37, and t = 10 years. We can rearrange the formula to solve for r:
r = (1/t) * ln(A(t)/A(0))
Substituting the known values, we get:
r = (1/10) * ln(22377.37/15000)
Solving this equation, we get r = 0.0658082.
Now that we have the value of r, we can use the formula for continuous compound interest to find the amount A in the account after 10 years:
A(10) = 15000 * e^(0.0658082 * 10)
Solving this equation, we get A(10) = $30,441.65.

Additional comment
The (inside) base angles of the outside two triangles are alternate interior angles with respect to the top two angles of the center triangle. Hence they are congruent. The center triangle is marked as equilateral, so its angles are all 60°. That means all of the acute angles in the figure are 60°.
Music stalls Games stalls Handicraft stalls Ks 3000 Food stalls Ks 4800 (a) How much money was collected by the music stalls? (b) What fraction of the total amount of money was collected by the game stalls? (c) What percentage of the total amount of money was collected by the food stalls? (d) What was the ratio of the money collected by the handicraft stalls to the money collected by the music stalls?
Answer:
Step-by-step explanation:
a. The music stalls collected Ks 3000.
b. The game stalls collected Ks 4800, which is a fraction of the total amount of money collected. To find the fraction, we can divide the amount collected by the game stalls by the total amount collected by all the stalls:
$\frac{Ks 4800}{Ks 3000 + Ks 4800 + Ks 3000} = \frac{Ks 4800}{Ks 10800} = \frac{2}{9}$
Therefore, the game stalls collected $\frac{2}{9}$ of the total amount of money.
c. The food stalls collected Ks 4800, which is a percentage of the total amount of money collected. To find the percentage, we can divide the amount collected by the food stalls by the total amount collected by all the stalls and multiply by 100%:
$\frac{Ks 4800}{Ks 3000 + Ks 4800 + Ks 3000} \times 100% = \frac{Ks 4800}{Ks 10800} \times 100% = 44.44%$
Therefore, the food stalls collected 44.44% of the total amount of money.
d. The handicraft stalls collected Ks 3000, and the music stalls collected Ks 3000. The ratio of the money collected by the handicraft stalls to the money collected by the music stalls is therefore 1:1. We can write this ratio as $\frac{1}{1} = 1$, or simply as 1.

Let x,X. X30o be a random sample from Gamma(3, 2). Find an approximate probability that x is less than 6.3 (round off to third decimal place) 42300
0.933 is approximate probability that x is less than 6.3 (round off to third decimal place).
What is Probability?
Calculating or estimating how likely or "possible" something is to occur is the subject of probability.
Words like "certain," "impossible," or "probable" can be used to express the likelihood of an event occurring.
Probabilities in mathematics are always represented as fractions, decimals, or percentages with values ranging from 0 to 1.
Given X₁,X₂, ............X₃₀₀ are IID random samples from Xi ~ Gamma ( shape = 3 scale = 2 ) . The mean and variance are
E(Xi) = 3 * 2 = 6
Var (Xi) = 3 * 2² = 12
According to CLT,
X = X₁ + X₂ + ............+ X₃₀₀/300
has approximately normal distribution X ~ N( 6,12/300) So the probability,
P( X < 6.3 ) = P( Z < 6.3 - 6/√12/300
P ( X < 6.3 ) = P( Z < 1.5 )
P (X < 6.3 ) = Ф (1.5 )
P (X < 6.3 ) = 0.933
