What are trigonometric relations?The trigonometric functions in mathematics are real functions that connect the right-angled triangle's angle to the ratios of its two side lengths. They are extensively employed in all fields of geometry-related study, including geodesy, solid mechanics, celestial mechanics, and many others.
Here, we have
Given: Let the triangle be ΔABC
The triangle ABC is a right-angled triangle and the angles inside the triangles are 45°, 45° and 90°
tan θ = x / 3
Now , θ = 45°
So, tan 45° = x / 3
The value of x is 3.
Hence, the value of x is 3.

William invested $550 in an account paying an interest rate of 2% compounded monthly. Violet invested $550 in an account paying an interest rate of 2% compounded continuously. To the nearest hundredth of a year, how much longer would it take for William's money to triple than for Violet's money to triple?
Answers
Answer:
We can use the formula A = P(1 + r/n)^(nt) to find out how long it takes for William's money to triple, where A is the final amount, P is the principal, r is the interest rate, t is the time in years and n is the number of times the interest is compounded per year.
A = P(1 + r/n)^(nt) = 550(1 + 0.02/12)^(12*t) = 3P
Solving for t we get
t = (ln(3)/ln(1+0.02/12))/12 = 49.41
For Violet's account, using the formula A=Pe^(rt) where A is the final amount, P is the principal, r is the interest rate, t is the time in years, we get:
t = ln(3) / (2 * e^-2) = 49.41
Therefore, it will take approximately 49.41 years for William's money to triple, and 49.41 years for Violet's money to triple.
So the difference in time is 0.

Answers
The hybrid factor is f(w) Equals 50w + 25 according to the preceding statement. The hybrid value is measured in units of f (flowers) and w (weeks), etc. 30 weeks of Part A's synthesis function equal 1525.
What exactly are function and example?A task is a type of rule that produces one output for a single input. Source of the image: Alex Federspiel. This is illustrated by the equation y=x2. Any input for x results in a single output for y. Considering that x is just the input value, we would state that y is a mathematical function
Given that:
f(s) = 2s + 25
s(w) = 25w
The following combination function is used to determine how many flowers will blossom over the course of w weeks: f(w)
f(s) = 2s + 25
Replace s with s(w)
f(s(w)) = 2(s(w)) + 25
Substitute s(w) = 25w
f(s(w)) = 2(25w) + 25
f(s(w)) = 50w + 25
Hence,
f(w) = 50w + 25
Flowers are used as the units of measurement for f(w).
30 weeks of flowers translates to:
w = 30
So, we have:
f(30) = 50*30+25
f(30) = 1525
Thus, there will be 1525 blossoms throughout the course of 30 weeks.

many more workers must transfered from other departments so that 70% of the people are assembling yo-yo's?
Answers
Answer:
12 people
Step-by-step explanation:
Total people in the company = 120
No. of People who assemble yo- yo's = 120 × (60/100

4. you are looking for a deep spot to take a swim in a local river. the width of the river is about the same all along its length, but there are places where the water flows quickly and places where it flows slowly. which is a better choice for a swim?
Answers
The best choice for a deep spot to take a swim is to go to a place in the river where the cross-sectional area is larger, and the water flows slower.
If you are looking for a deep spot to take a swim in a local river, the best choice is to go where the water flows slowly. The speed of the water is determined by the formula:
v=Q/A,
where v is the speed of the water, Q is the discharge rate, and A is the cross-sectional area of the river. As Q is constant for the same river, a slower water flow can be achieved by increasing A, which is the cross-sectional area of the river. Therefore, the best choice for a deep spot to take a swim is to go to a place in the river where the cross-sectional area is larger, and the water flows slower.

Answers
The total cost of the meal was $16.189.
What is the sales tax?
A sales tax is a consumption tax that is added to the price of goods and services. It is usually a percentage of the purchase price, and the percentage varies depending on the location and type of product or service.
We are trying to find the total cost of the meal including the sales tax. To do this, we need to calculate the amount of tax and add it to the cost of the meal.
The cost of the meal before tax is $15.20 and the sales tax rate is 6.5%. To find the amount of sales tax, we can multiply the cost of the meal by the sales tax rate as a decimal.
$15.20 x 0.065 = $0.989
The amount of sales tax is $0.989.
To find the total cost of the meal, we can add the amount of sales tax to the cost of the meal before tax.
$15.20 + $0.989 = $16.189
Hence, The total cost of the meal was $16.189.

mouth and starts to play. Which statement correctly connects the motion of the trumpet with Newton's first law of motion?
OA. A tuba has more mass than a trumpet, so it has greater inertia.
OB. The trumpet automatically stops moving without a force acting on it.
OC. The trumpet starts moving because a net force overcomes the trumpet's inertia.
OD. Andrew exerts an action force on the trumpet, and the trumpet exerts a reaction force on Andrew.
Answers
Option C connects the motion of the trumpet with Newton's first law of motion. The trumpet starts moving because a net force overcomes the trumpet's inertia.
What is Newton's first law of motion?According to Newton's first law of motion, a body won't begin to move unless and until an outside force acts on it. When anything starts moving, it won't stop or vary its speed unless another force acts on it. The law of inertia is another name for the first law of motion.
Given, The concert band's trumpet player is Andrew. Until it is time for him to play, he keeps the instrument still at his side. He positions the trumpet next to his mouth and begins to play afterward.
First of all, there are no movements, no acceleration, and no velocity for the trumpet. Newton's first law of motion, which states that an object at rest stays at rest and an object in motion stays in motion with the same speed and direction unless acted upon by an unbalanced force, explains why the trumpet is in this state. The trumpet continues to move at zero velocity since there is no net force exerted on it.
The trumpet is then moved by Andrew. It indicates that Andrew pushed the trumpet with vigor. It caused the body to transition from the resting condition to the moving state.
Finally, we can draw the conclusion that Trumpet will remain at rest unless Andrew applies a net force that is different from zero in accordance with Newton's first law of motion.
Hence, The trumpet starts moving because a net force overcomes the trumpet's inertia.

a piece of wire 10m long is cut into 2 pieces. one piece is bent into a square and the other into a circle. how much of the wire should be used for the square if you want to minimize the total enclosed area? please give an exact simplified answer.
Answers
Bend 4.4 m of the wire into a circle and bend 5.6 m of the wire into a square in order to minimize the total area.
Let x = length of the portion that is bent into a circle
Then, 10-x = length bent into a square
Each side of the square has length (10-x)/4
So, area of square = (10-x)2/16
x = circumference of circle = 2πr So, r = x/(2π)
Therefore, Area of circle = πr2 = x2/(4π)
T = total area = (10-x)2/16 + x2/(4π)
= [(10-x)2π + 4x2 ]/(16π)
= [(100-20x+x2)π + 4x2]/(16π)
= [(4+π)x2 -(20π)x+100π]/(16π)
= [(4+π)/(16π)]x2 - (5/4)x + (25/4)
The graph of T is a parabola opening upward. The minimum of T occurs at the vertex of the parabola.
The x coordinate of the parabola is (5/4)/[(4+π)/(8π)] = (10π)/(4+π) ≈ 4.4
Thus, Bend 4.4 m of the wire into a circle and bend 5.6 m of the wire into a square in order to minimize the total area.

Imagine you have a classmate who has never had an introduction to statistics in a math course. Explain to that person how the probability of selecting a red tile is determined. Use complete sentences.
Answers
The probability of selecting a red tile is determined by the formula number of red tiles/total number of tiles.
Probability is used to determine the chances of events.
To calculate the probability of selecting a red tile, we start by:
Get the number of red tiles
The total number of tiles
Then we need to divide the number of red tiles by the total number of tiles.
According to the question, there are 15 red tiles in a total of 60 tiles, then the probability of selecting a red tile is:
P(red) = 15/60
Divide 15 by 60
P(red) = 0.25
Thus, the probability of selecting a red tile for the given values is 0.25.
