Step-by-step explanation:
A hockey net is 1.8 m wide. A player is 6 m from one goal post and 6.7 m from the other. Within
What angle must she Keep her shot in order to score a goal?
To calculate the angle required for the shot to score a goal in hockey, we can use trigonometry.
The distance between the player and the center of the net can be found by calculating the midpoint between the two goal posts, which is (1.8 m/2) = 0.9 m from each post. Therefore, the distance from the player to the center of the net is (0.9 m + 6 m) = 6.9 m.
To find the angle within which the player must shoot to score a goal, we can use the Law of Cosines. Let's label the points as follows:
- A: the position of the player
- B: the first goal post (6 m away)
- C: the second goal post (6.7 m away)
- D: the point on the net directly across from the player
The width of the net (1.8 m) is the length of segment CD.
1. Calculate the length of segment AD using the Pythagorean theorem:
AD = √(AC² - CD²) = √(6.7² - 1.8²) ≈ 6.54 m
2. Now, apply the Law of Cosines to find the angle ∠BAD:
cos(∠BAD) = (AB² + AD² - BC²) / (2 * AB * AD) = (6² + 6.54² - 6.7²) / (2 * 6 * 6.54) ≈ 0.531
3. Calculate the angle ∠BAD:
∠BAD = arccos(0.531) ≈ 58.3°
The player must keep her shot within an angle of approximately 58.3° to score a goal.

"Derive the demand function
Endowment (1,0)
U(x,y) = -e⁻ˣ — e⁻ʸ
To derive the demand function from the given utility function and endowment, we need to determine the optimal allocation of goods that maximizes utility. The utility function is U(x, y) = -e^(-x) - e^(-y), and the initial endowment is (1, 0).
To derive the demand function, we need to find the optimal allocation of goods x and y that maximizes the given utility function while satisfying the endowment constraint. We can start by setting up the consumer's problem as a utility maximization subject to the budget constraint. In this case, since there is no price information provided, we assume the goods are not priced and the consumer can freely allocate them.
The consumer's problem can be stated as follows:
Maximize U(x, y) = -e^(-x) - e^(-y) subject to x + y = 1.
To solve this problem, we can use the Lagrangian method. We construct the Lagrangian function L(x, y, λ) = -e^(-x) - e^(-y) + λ(1 - x - y), where λ is the Lagrange multiplier.
Taking partial derivatives of L with respect to x, y, and λ, and setting them equal to zero, we can find the values of x, y, and λ that satisfy the optimality conditions. Solving the equations, we find that x = 1/2, y = 1/2, and λ = 1. These values represent the optimal allocation of goods that maximizes utility given the endowment.
Therefore, the demand function derived from the utility function and endowment is x = 1/2 and y = 1/2. This indicates that the consumer will allocate half of the endowment to each good, resulting in an equal distribution.

If the surface area of a sphere is 144pi square centimeters, what is the length of the radius of the sphere, in centimeters
Answer:
6cm
Step-by-step explanation:
The formula for the surface area of a sphere = 4πr²
From the Question, we are given:
The surface area of a sphere = 144pi square centimeters = 144π cm²
The length of the radius of the sphere, in centimeters is calculated by:
4πr² = 144π
Divide both sides by 4π
4πr²/4π = 144π/4π
r² = 36
Square root both sides
√r² = √36
r = 6cm
Therefore, the length of the radius of the sphere, in centimeters is 6 centimeters.
In ΔABC, ∠A = 50° and the external bisectors of ∠B and ∠C meet at O as shown in figure. The measure of ∠BOC is
Answer:
17
Step-by-step explanation:
Look at Triangle ABC, The rays meet at line BC and they are both from the interior point A. So this means that AB=AC. This makes ABC a isosceles triangle. Using the isosceles triangle theorem, Angle B and Angle C measure is equal to each other so
\(50 + x + x = 180\)
\(50 + 2x = 180\)
\(2x = 130\)
\(x = 65\)
This means angle b and C of the triangle ABC measure is 65.
External bisector bisect a figure that it makes the original angle split into half that they are equal to each other.
This means the angle below Angle B and angle C measure is 32.5. We can find the measure of Angle B and C in triangle BOC. This is a isosceles triangle as well so
\(32.5 + 65 + x = 180\)
\(98.5 + x = 180\)
\(x = 81.5\)
Angle C is 81.5 as well so
\(81.5 + 81.5 = 163\)
Find angle o
\(180 - 163 = 17\)
how many subsets of {1, 2, 3, 4, 5, 6, 7, 8} of size two (two elements) contain at least one of the elements of {1, 2, 3}?
There are 42 subsets of size two that contain at least one of the elements of {1, 2, 3}.
There are \(${8\choose2}=28$\) subsets of size two that can be formed from the set {1, 2, 3, 4, 5, 6, 7, 8}.
To count the number of subsets of size two that contain at least one of the elements of {1, 2, 3}, we can use the principle of inclusion-exclusion.
Let A be the set of subsets of size two that contain 1, B be the set of subsets of size two that contain 2, and C be the set of subsets of size two that contain 3. We want to count the size of the union of these three sets, i.e., the number of subsets of size two that contain at least one of the elements of {1, 2, 3}.
By the principle of inclusion-exclusion, we have:
|A ∪ B ∪ C| = |A| + |B| + |C| - |A ∩ B| - |A ∩ C| - |B ∩ C| + |A ∩ B ∩ C|
To calculate the sizes of these sets, we can use combinations. For example, |A| is the number of subsets of size two that can be formed from {1, 2, 3, 4, 5, 6, 7, 8} with 1 as one of the elements. This is equal to \(${3\choose1}{5\choose1}=15$\), since we must choose one of the three elements in {1, 2, 3} and one of the five remaining elements.
Similarly, we have:
|A| = \(${3\choose1}{5\choose1}=15$\)
|B| = \(${3\choose1}{5\choose1}=15$\)
|C| = \(${3\choose1}{5\choose1}=15$\)
|A ∩ B| = \(${2\choose1}{5\choose0}=2$\), since there are two elements in {1, 2} that must be included in the subset, and we can choose the other element from the remaining five.
|A ∩ C| = \(${2\choose1}{5\choose0}=2$\)
|B ∩ C| = \(${2\choose1}{5\choose0}=2$\)
|A ∩ B ∩ C| = \(${3\choose2}=3$\), since there are three elements in {1, 2, 3} and we must choose two of them.
Substituting these values into the inclusion-exclusion formula, we get:
|A ∪ B ∪ C|\(= 15 + 15 + 15 - 2 - 2 - 2 + 3 = 42\)
Therefore, there are 42 subsets of size two that contain at least one of the elements of {1, 2, 3}.

The function that represents the distance a dropped coin purse falls in t seconds,
\($f(t)=144-16 t^2$\)
When the coin purse touches the ground,
\($f(t)=0$\)
\($0=144-16 t^2$\)
\($t^2=\frac{144}{16}=9$\)

5/8 - 5/24
I am doing some homework my brain isnt working right now can someone help me out?
Answer:
5/12
Step-by-step explanation:
i just looked it up...
====================================================
Explanation:
Multiply top and bottom of 5/8 by 3 to get 15/24
This means 5/8-5/24 is the same as 15/24-5/24
The denominators are the same, so we can subtract the numerators to have them placed over the common denominator
15/24 - 5/24 = (15-5)/24 = 10/24
Then we reduce by dividing each part of the fraction by the GCF 2
10/2 = 5
24/2 = 12
Meaning that 10/24 = 5/12
Note how multiplying top and bottom of 5/12 by 2 leads to 10/24 again.
So overall,
5/8 - 5/24 = 5/12

if we compute a 95onfidence interval 12.65 ≤ μ ≤ 25.65 , then we can conclude that.
Based on the computed 95% confidence interval, we can conclude that we are 95% confident that the true population mean falls within the range of 12.65 to 25.65.
A confidence interval is a range of values that provides an estimate of the true population parameter. In this case, we are interested in estimating the population mean (μ). The 95% confidence interval, as mentioned, is given as 12.65 ≤ μ ≤ 25.65.
Interpreting this confidence interval, we can say that if we were to repeat the sampling process many times and construct 95% confidence intervals from each sample, approximately 95% of those intervals would contain the true population mean.
The confidence level chosen, 95%, represents the probability that the interval captures the true population mean. It is a measure of the confidence or certainty we have in the estimation. However, it does not guarantee that a specific interval from a particular sample contains the true population mean.
Therefore, based on the computed 95% confidence interval, we can conclude that we are 95% confident that the true population mean falls within the range of 12.65 to 25.65.
