which expression gives the distance between the two points (2,3) and (4,-3)
Answers
The expression that will give the distance between points is option D i.e. √(2 - 4)² + (3 + 3)². The solution has been obtained by using distance formula.
What is the distance formula?
The distance between two locations on a coordinate plane can be calculated using the distance formula. The distance equation is written as d = √(x₂ - x₁)² + (y₂ - y₁)².
We are given two points as (2,3) and (4,-3).
So, x₁ = 2, y₁ = 3, x₂ = 4, y₂ = -3
Now, substituting these values in the distance formula, we get
d = √(2 - 4)² + (3 + 3)²
Hence, the expression that will give the distance between points is option D.

In this case, the restricted domain would be all real numbers, because the function f(x) = x^2 + 6x - 9 is defined for all x in the real numbers and the range of the function is also the real numbers. Thus, the function is both injective and surjective, and it has an inverse.
Note that the inverse of f(x) = x^2 + 6x - 9 is not a simple expression like the original function, but it can be found by interchanging the variables and solving for y, as long as y = f(x).
Determine if events A and B are independent.
Answers
P(A)=1/5, P(B)=7/20, P(A and B)= 7/100. The events A and B are independent.
What is independent probability?Two events are independent if the occurrence of one event does not affect the chances of the occurrence of the other event. The mathematical formulation of the independence of events A and B is the probability of the occurrence of both A and B being equal to the product of the probabilities of A and B (i.e., P(A and B).
1) P(A)=1/5, P(B)=7/20, P(A and B)= 7/100
Here, P(A and B)= P(A)×P(B)
= 1/5 × 7/20
= 7/100
So, the events A and B are independent.
2) P(A)=13/20, P(B)=13/20, P(A and B)= 169/400
Here, P(A and B)= P(A)×P(B)
= 13/20 × 13/20
= 169/400
So, the events A and B are independent.
3) P(A)=7/10, P(B)=2/5, P(A and B)= 21/100
Here, P(A and B)= P(A)×P(B)
= 7/10 × 2/5
= 14/50
So, the events A and B are not independent.
2) P(A)=1/5, P(B)=1/5, P(A and B)= 1/25
Here, P(A and B)= P(A)×P(B)
= 1/5 × 1/5
= 1/25
So, the events A and B are independent.

Answers
The correct equations for the measures of the unknown angles x and y are:
x = cos(a), y = sin(a).
The trigonometric functions (sin, cos, tan) are mathematical functions that describe the relationships between the sides and angles of a right triangle. Given an angle a in a right triangle, we can use these functions to find the values of the side ratios for that angle. For example:
sin(a) = opposite side / hypotenuse
cos(a) = adjacent side / hypotenuse
tan(a) = opposite side / adjacent side
In these expressions, "opposite side" refers to the side opposite the angle a, "adjacent side" refers to the side adjacent to the angle a, and "hypotenuse" refers to the longest side in the right triangle (the one opposite the right angle).
The inverse trigonometric functions[tex](sin^-1, cos^-1, tan^-1)[/tex] are the reverse of the trigonometric functions. Given a value of a trigonometric function, the inverse function returns the measure of the angle (in radians) for which that value is the result. For example:
[tex]sin^-1(y) = a (where y = sin(a))cos^-1(x) = a (where x = cos(a))tan^-1(t) = a (where t = tan(a))[/tex]

The cost of fuel per litre is calculated using the following formula. (1 + 100) X + X 160 C = cost of oil per barrel. F = rate of fuel duty tax in %. P = percentage profit the petrol station wants to make. Fuel duty is 50%, and oil costs £128 per barrel. A petrol station wants to make 100% profit. Work out the cost of fuel per litre at this petrol station.
Answers
If a petrol station wants to make 100% profit. the cost of fuel per litre at this petrol station is 1.4 pence.
How to find the cost?Given, the formula to calculate the cost of fuel per litre:
(1 + 100) X + X 160 C = cost of oil per barrel.
Where :
X = cost of oil per litre
C= rate of fuel duty tax in %.
We know that fuel duty is 50% and oil costs £128 per barrel, so we can substitute these values into the equation:
(1 + 100) X + X 160 * 0.5 = 128
Expanding the equation:
100 X + 80 X = 128
180 X = 128
Dividing both sides by 180:
X = 128/180 = 7/10 = 0.7
So, the cost of oil per litre is 0.7 pence.
The petrol station wants to make 100% profit, so we add the profit to the cost of oil per litre:
0.7 + 0.7 * (100/100) = 1.4 pence
Therefore, the cost of fuel per litre at this petrol station is 1.4 pence.

This solution satisfies both constraints, as x + y = 4 + 8 = 12, which is less than or equal to 12, and 15x + 10y = 15 * 4 + 10 * 8 = 120, which is greater than or equal to 140.
What is inequality?
In mathematics, a relationship between two expressions or values that are not equal to each other is called 'inequality. ' So, a lack of balance results in inequality.
We can write the first inequality as x + y <= 12
This inequality represents the constraint that Mav can work at most 12 hours in total between both jobs.
The second inequality represents the constraint that Mav must earn no less than $140 in a given week, which can be written as:
15x + 10y >= 140
To graph the system of inequalities, we can plot the lines corresponding to x + y = 12 and 15x + 10y = 140 on the coordinate plane and shade the region that satisfies both inequalities.
The solution to the system of inequalities will be the values of x and y that lie in the shaded region.
One possible solution is x = 4 and y = 8, which means that Mav works 4 hours of lifeguarding and 8 hours of landscaping in a given week, earning a total of 15 * 4 + 10 * 8 = $120.
Hence, This solution satisfies both constraints, as x + y = 4 + 8 = 12, which is less than or equal to 12, and 15x + 10y = 15 * 4 + 10 * 8 = 120, which is greater than or equal to 140.

A tank in the shape of a hemisphere has a radius of 5 feet. If the liquid that fills the tank has a density of 62. 7 pounds per cubic foot, what is the total weight of the liquid in the tank, to the nearest full pound?
Answers
The total weight of the liquid in the tank which is hemisphere in shape is 16,415 pounds.
The density and mass are related to each other with the formula -
Density = mass/volume
So, we have the density. We need to calculate the volume of hemisphere which will be accomodating the liquid. Then we will find the mass.
Volume of hemisphere = 2/3πr³, where r represents radius.
Volume = 2/3×π×5³
Performing multiplication, division and taking cube
Volume = 261.8 feet³
Now, mass = density × volume
Mass = 62.7 × 261.8

Answers
The probability that a randomly selected worker lives more than 5 miles from work and rides their bicycle is 57%.
To calculate the probability that a randomly selected worker lives more than 5 miles from work and rides their bicycle, we need to use the data from the survey. Let's assume that the survey results are summarized in the following table (attached) :
From this table, we can see that the probability of a worker living more than 5 miles from work is 35%. We can also see that the probability of a worker riding their bicycle is 50%, and the probability of a worker living more than 5 miles from work and riding their bicycle is 20%.
To calculate the probability that a randomly selected worker lives more than 5 miles from work and rides their bicycle, we can multiply the probabilities of these two events:
P(Lives > 5 miles and Rides Bicycle) = P(Lives > 5 miles) x P(Rides Bicycle | Lives > 5 miles)
= 35% x (20%/35%)
= 0.5714 or 57% (rounded to the nearest whole percent)
Therefore, the probability that a randomly selected worker lives more than 5 miles from work and rides their bicycle is 57%.

The total number of ways to form 3 groups comprising of 3, 3 and 2 students is calculated by multiplying the individual numbers of ways, which results in 280.
The formula for calculating the number of unique ways to form three groups comprising of 3, 3, and 2 students is given by:
Number of ways = Number of ways to select 3 first-year students from 5 first-year students x Number of ways to select 3 second-year students from 3 second-year students x Number of ways to select 2 students from 8 students

Therefore, there are 280 unique ways to form three groups comprising 3, 3, and 2 students. This can be seen by considering the total number of possible arrangements of the 8 students into 3 groups of 3, 3 and 2. First, we need to select 3 students from 5 first-year students in 5C3 ways, which is equal to 10. Second, we need to select 3 students from 3 second-year students in 3C3 ways, which is equal to 1. Finally, we need to select 2 students from 8 students in 8C2 ways, which is equal to 28.

The blank in the statement should be filled in with "ΔVYZ." which is proven by the definition of congruence.
What is a Triangle?Triangle is defined as a basic polygonal shape of a triangle that has three sides and three interior angles. It is one of the fundamental shapes in geometry and is represented by the symbolΔ.
Since S, T, and U are midpoints in ΔVYZ, it follows that:
ST is a median of ΔVYZ, meaning it bisects the side VZ into two equal parts.
TU is a median of ΔVYZ, meaning it bisects the side VY into two equal parts.
SV is a median of ΔVYZ, meaning it bisects the side YZ into two equal parts.
Using the definition of congruence, two triangles are congruent if their corresponding sides are equal in length and their corresponding angles are equal in measure. Since medians bisect their corresponding sides, it follows that all three pairs of corresponding sides in ΔYST, ΔTUZ, and ΔSVU are equal in length.
Furthermore, since the medians divide the triangle into two smaller triangles that are similar to the original triangle, it follows that the corresponding angles in ΔYST, ΔTUZ, and ΔSVU are equal in measure.
Therefore, ΔYST ≅ ΔTUZ ≅ ΔSVU ≅ ΔVYZ.

The mean provides a general sense of the distribution of the data and helps to identify any patterns or trends. In the stem-and-leaf plot, the mean can be calculated by adding up all the values and dividing by the number of throws. The mean in this case is 4.62 feet, which indicates that a typical throw of the ball results in 4.62 feet. This value can be used to gain a better understanding of the overall performance of the ball thrower and provide insight into how far the ball is typically thrown.
It is important to note that the mean is sensitive to outliers or extreme values, so it may not accurately reflect the typical value of the data in all cases. However, in this particular case, the mean provides a useful representation of the typical performance of the ball thrower.
