In circle I, IJ=4 and mJIK∠=90∘ Find the area of shaded sector. Express your answer as a fraction times π.
The area of the shaded sector is 4π square units.
To find the area of the shaded sector, we need to calculate the central angle formed by the sector. In this case, we are given that the angle JIK is 90 degrees, which means it forms a quarter of a full circle.
Since a full circle has 360 degrees, the central angle of the shaded sector is 90 degrees.
Next, we need to determine the radius of the circle. The line segment IJ represents the radius of the circle, and it is given as 4 units.
The formula to calculate the area of a sector is A = (θ/360) * π * r², where θ is the central angle and r is the radius of the circle.
Plugging in the values, we have A = (90/360) * π * 4².
Simplifying, A = (1/4) * π * 16.
Further simplifying, A = (1/4) * π * 16.
Canceling out the common factors, A = π * 4.
Hence, the area of the shaded sector is 4π square units.
Therefore, the area of the shaded sector, expressed as a fraction times π, is 4π/1.
In summary, the area of the shaded sector is 4π square units, or 4π/1 when expressed as a fraction times π.

light travels 186,000 miles per second. it takes light 4.2 years to travel from earth to the nearest star, proxima centari. how far away is the nearest star in miles?
Proxima Centauri, the nearest star to Earth, is approximately 24.9 trillion miles away. This distance is calculated using the speed of light and the time it takes for light to travel from Earth to Proxima Centauri.
To calculate the distance between Earth and Proxima Centauri, we can use the formula: distance = speed x time. In this case, the speed of light is 186,000 miles per second and the travel time is 4.2 years. First, we need to convert the travel time into seconds.
There are 31,536,000 seconds in a year (60 seconds x 60 minutes x 24 hours x 365 days).
Therefore, 4.2 years is equivalent to 132,451,200 seconds (4.2 years x 31,536,000 seconds/year). Now, we can plug these values into the formula: distance = 186,000 miles/second x 132,451,200 seconds.
This calculation results in a distance of approximately 24.9 trillion miles (24,900,000,000,000 miles).

- Mariana debe tomar dos pastillas; una cada 6 horas y otra cada 9 horas. Si a cierta hora toma las dos pastillas juntas, ¿después de cuantas horas volverá a tomarlas simultáneamente?
Answer:
Mariana takes the two pills together after 18 hours.
Step-by-step explanation:
Mariana must take two pills; one every 6 hours and another every 9 hours.
She take two pills together. Let she takes the two pills together after t hours at the time when she take initially.
To find the time to take the two pills together, take the least common multiple of 6 and 9.
6 = 2 x 3
9 = 3 x 3
So, the least common multiple is 2 x 3 x 3 = 18
So, she takes the two pills together after 18 hours.

It is believed that 11% of all Americans are left-handed. In a random sample of 150 students from a particular college with 4293 students, 19 were left- handed. We want to find a 99% confidence interval for the percentage of all students at this particular college who are left-handed. What conditions do we need to check before proceeding with finding an interval? Check all that apply. On > 30 or normal population Oo is unknown On(1-P) > 10 On (1-P) > 10 O np > 10 OnÔ) > 10 o is known
We can proceed with finding a 99% confidence interval for the percentage of all students at this particular college who are left-handed because Np=472.23, which is greater than 10, and N(1-p)=3833.77, which is also greater than 10.
There are two conditions that we need to check before proceeding with finding an interval:
1. Np>10
2. N(1-p)>10
For calculating the confidence interval for the percentage of all students at a particular college who are left-handed, we need to check two conditions:
1. The sample size (n) should be large enough. Since the sample size is greater than 30, we can use the normal distribution for calculation.
2. We need to check the proportion of the population who are left-handed. In this case, the proportion of left-handed students in the sample is 19/150=0.1267.
Therefore, we can use the normal distribution to calculate the confidence interval only if the following two conditions are met:
1. Np>10, where n is the sample size and p is the proportion of the population who are left-handed. In this case, Np=4293*0.11=472.23, which is greater than 10.
2. N(1-p)>10. In this case, N(1-p)=4293*(1-0.11)=3833.77, which is greater than 10.
Therefore, we can proceed with finding a 99% confidence interval for the percentage of all students at this particular college who are left-handed.

a person creates a six foot shadow from a light that is mounted on a building 10 ft from the ground. if the person is seven feet from the building at that moment, what is their approximate height?
The person's approximate height can be determined by using a similar triangle and the properties of shadows.
When a person stands in the sunlight, they cast a shadow on the ground. The length of the shadow depends on various factors such as the height of the person and the angle of the sun's rays. In this scenario, we have a person standing seven feet away from a building with a light mounted on it, and the light is ten feet from the ground. By understanding the relationship between the person's distance from the light and the length of their shadow, we can estimate the person's approximate height.
To solve this problem, we can make use of similar triangles and proportions. Let's consider the triangles formed by the person, their shadow, and the building.
We have two similar right triangles:
Triangle 1: The person's height (let's call it "h") is the vertical side, and the length of their shadow is the horizontal side.
Triangle 2: The height of the building (10 ft) is the vertical side, and the distance between the person and the building (7 ft) plus the length of their shadow is the horizontal side.
Since the two triangles are similar, their corresponding sides are proportional. We can set up the following proportion:
(h / shadow length) = (10 ft / (7 ft + shadow length))
Cross-multiplying and simplifying the equation, we get:
h * (7 ft + shadow length) = 10 ft * shadow length
Expanding the equation, we have:
7h ft + h * shadow length = 10 * shadow length ft
Rearranging the equation to isolate the shadow length, we get:
h * shadow length - 10 * shadow length = -7h ft
Factoring out the shadow length, we have:
shadow length * (h - 10) = -7h ft
Dividing both sides by (h - 10), we obtain:
shadow length = (-7h) / (h - 10) ft
Given that the person's shadow length is six feet, we can substitute this value into the equation:
6 ft = (-7h) / (h - 10) ft
Now, we can solve for the person's height (h):
6 ft * (h - 10) ft = -7h ft
6h - 60 = -7h
Combining like terms, we get:
13h = 60
Dividing both sides by 13, we find:
h = 60 / 13 ≈ 4.62 ft
Therefore, the person's approximate height is around 4.62 feet.

y varies jointly as x and z. If y = 12 when x = 4 and z = 3, find y when x = 9 and z = 8.
Answer:
y = 72
Step-by-step explanation:
Given y varies jointly as x and z then the equation relating them is
y = kxz ← k is the constant of variation
To find k use the condition y = 12 when x = 4 and z = 3
12 = k × 4 × 3 = 12k ( divide both sides by 12 )
1 = k
y = xz ← equation of variation
When x = 9 and z = 8 , then
y = 9 × 8 = 72

y = 2*(x + 1)²*(x + 4)
How to find the equation of the polynomial?A polynomial of degree N with the zeros {x₁, x₂, ...} and a leading coefficient a can be written as:
y = a*(x - x₁)*(x - x₂)*...*(x - xₙ)
Here we know that the degree is 3, and the zeros are {-1, -4, -1}
Then we can write the polynomial as:
y = a*(x + 1)*(x + 4)*(x + 1)
y = a*(x + 1)²*(x + 4)
We also know that the polynomial passes through (0, 8), replacing these values we will get:
8 = a*(0 + 1)²^*(0 + 4)
8 = a*1*4

A paving company is paving the rectangular student parking lot at hamilton high school. the length of the parking lot can be represented as (5 − 7) and the width as (3 + 4) . which expression represents the area of the parking lot?
The expression that represents the area of the parking lot is (5 - 7) * (3 + 4).
How to express the area of the parking lot?The length of the parking lot can be represented as (5 - 7), which simplifies to -2. The width of the parking lot can be represented as (3 + 4), which simplifies to 7. To find the area of a rectangle, we multiply the length by the width.
Therefore, the expression that represents the area of the parking lot is (-2) * 7. Multiplying -2 by 7 gives us -14. So, the area of the parking lot is -14 square units.
However, it is important to note that negative areas do not have practical meaning in this context, as areas are typically positive values. Therefore, the area of the parking lot would be considered 14 square units.

minimize f(x) = |x+3| + x^3 S.t. x sum [-2, 6]
Minimization of f(x) = |x+3| + x^3 at the endpoints (-2 and 6) the minimum value of the function is approximately 3.84, which occurs at x= \sqrt{1/3}
within the given interval.
To minimize the function subject to the constraint f(x) = |x+3| + x^3 that x lies in the interval [-2, 6], we need to find the value of x that minimizes f(x) within that interval.
First, let's analyze the function f(x). The absolute value term |x+3| can be rewritten as:
|x+3| =
x+3 if x+3 >= 0
-(x+3) if x+3 < 0
Since the interval [-2, 6] includes both positive and negative values of x+3, we need to consider both cases.
Case 1: x+3 >= 0
In this case, f(x) = (x+3) + x^3 = 2x + x^3 + 3
Case 2: x+3 < 0
In this case, f(x) = -(x+3) + x^3 = -2x + x^3 - 3
Now, we can find the minimum of f(x) within the given interval by evaluating the function at the endpoints (-2 and 6) and at any critical points within the interval.
Calculating the values of f(x) at x = -2, 6, and the critical points, we can determine the minimum value of f(x) and the corresponding value of x.
Since the equation involves both absolute value and a cubic term, it is not possible to find a closed-form solution or an exact minimum value without numerical methods or approximation techniques.

write and albegraic expression for thecoordinates o each endpoint of a line segment whose midpoint is the origin
The algebraic expression for the coordinates of each endpoint of a line segment whose midpoint is the origin is Endpoint 1: (-x₂, -y₂) and Endpoint 2: (x₂, y₂). The values of x₂ and y₂ determine the specific coordinates of the endpoints.
To determine the algebraic expression for the coordinates of each endpoint of a line segment whose midpoint is the origin, we can use the midpoint formula. Let's denote the coordinates of the endpoints as (x₁, y₁) and (x₂, y₂).
Since the midpoint is the origin, the coordinates of the midpoint are (0, 0). According to the midpoint formula, the coordinates of the midpoint are the average of the coordinates of the endpoints:
x₁ + x₂ = 2 * 0 = 0
y₁ + y₂ = 2 * 0 = 0
Simplifying these equations, we get:
x₁ + x₂ = 0
y₁ + y₂ = 0
We have two variables and two equations, so we can solve this system of equations to express one variable in terms of the other.
Solving for x₁, we get:
x₁ = -x₂
Solving for y₁, we get:
y₁ = -y₂
Therefore, the algebraic expression for the coordinates of each endpoint is:
Endpoint 1: (-x₂, -y₂)
Endpoint 2: (x₂, y₂)
The coordinates of the endpoints depend on the value of x₂ and y₂, which can be any real numbers.
