The solution of the triangle is shown below;

Angle A - 26.98°

Angle C - 118.6°

Side c -  47.98

If you know the length of one side and the measure of the opposite angle, or the length of two sides and the measure of the angle between them, you can use the Law of Sines to find the other parts of the triangle.

Using the sine rule;

a/Sin A = b/Sin B

aSin B = bsinA

Sin A = bSinB/a

A = Sin-1( bSinB/a)

A = Sin-1(30.9 * Sin 34.42/38.5)

A = 26.98°

Then;

C = (180 - 26.98 + 34.42)

C = 118.6°

Using the sine rule again;

b/sinB = c/Sin C

c = bSin C/Sin B

c = 30.9 * Sin 118.6/Sin 34.42

c = 27.12/0.565

c = 47.98

A graph is a non-linear kind of data structure made up of nodes or vertices and edges. The edges connect any two nodes in the graph, and the nodes are also known as vertices. This graph has a set of vertices V= { 1,2,3,4,5} and a set of edges E= { (1,2),(1,3),(2,3),(2,4),(2,5),(3,5),(4,50 }.

The graph shown in the problem has length as the vertical axis and nights as the horizontal axis.

The points through which the straight line passes are (0, 0) and (10, 20).

The equation of the line can be written as follows,

=> [tex]\frac{y-0}{x-0}=\frac{20-0}{10-0}[/tex]

=> [tex]\frac{y}{x}=\frac{20}{10}[/tex]

=> y = 2x

La fuerza con la que es lanzada una pelota de béisbol puede calcularse utilizando la segunda ley de Newton, que establece que la fuerza (F) es igual a la masa (m) multiplicada por la aceleración (a). En este caso, la masa de la pelota es de 0.126 kilogramos y la aceleración es de 3 m/s.

Aplicando la fórmula, la fuerza (F) se calcula de la siguiente manera:

F = m * a

F = 0.126 kg * 3 m/s

F = 0.378 N

Por lo tanto, la fuerza con la que se lanza la pelota de béisbol es de aproximadamente 0.378 Newtons.

Es importante tener en cuenta que este cálculo asume que la aceleración proporcionada es constante y que no hay otras fuerzas que actúen sobre la pelota durante el lanzamiento, como la resistencia del aire. Estas consideraciones pueden afectar la fuerza real experimentada por la pelota en un escenario práctico.

Rigid transformation refers to a type of geometric transformation that preserves the shape and size of an object. In other words, the transformed object is congruent to the original object.

Rigid transformations can be of two types -

Translation refers to moving an object in a straight line, while rotation refers to turning an object around a fixed point.

Rotation, in particular, has the effect of changing the orientation of the object. However, the length of each side and the angles between them will remain the same.

In a rigid transformation, the position of every point in the object is changed, but the distances between points remain unchanged, as well as the angles between lines and the area of the object.

Therefore, the population is at a maximum approximately 25 hours after the culture was started.

A function is a mathematical concept that describes a relationship between two sets of values, called the domain and the range. It is a rule or a set of rules that assigns a unique output value for every input value in the domain. In other words, it is a process that takes one or more inputs and produces a corresponding output. Functions are commonly represented using equations, graphs, or tables. They are used in various branches of mathematics, science, engineering, and technology to model real-world phenomena, make predictions, and solve problems.

Here,

To find the time at which the population is at a maximum, we need to find the time when the rate of change of population, or the derivative of p(t), is zero.

p(t) = -1715t² + 85,000t + 10,000

p'(t) = -3430t + 85,000

Setting p'(t) = 0, we get:

Alex's house is due west of Lexington and due south of Norwood. using Pythagorean theorem, the Norwood is 10 miles from Alex's house, measured in a straight line.

The Pythagorean theorem is a fundamental concept in mathematics that relates to the sides of a right triangle.

It states that in a right triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the lengths of the other two sides.

We can use the Pythagorean theorem to solve this problem.

Let x represents the distance we want to find.

Using the Pythagorean theorem, we can write:

[tex]x^2 = 6^2 + 8^2\\x^2 = 36 + 64\\x^2 = 100[/tex]

x = sqrt(100)

x = 10

Answer:

The glass cannot fit through the door.

Step-by-step explanation:

We can use the Pythagorean theorem to solve this problem. Let the height of the door be h.

We know that the diagonal of the glass must be able to fit through the door, so we can set up the following equation:

sqrt(8^2 + h^2) <= 3

Squaring both sides of the inequality, we get:

64 + h^2 <= 9

Subtracting 64 from both sides, we get:

h^2 <= -55

Since a square of a real number cannot be negative, there is no solution to this inequality.

Therefore, the glass cannot fit through the door, regardless of the height of the door.

The door must be at least √55 feet tall, which is approximately 7.42 feet, for the 8-foot wide glass to pass through the 3-foot wide door.

To determine how tall the door must be for the glass to pass through, we first need to calculate the height of the glass. Unfortunately, the height of the glass is not provided in the question. Assuming that the height of the glass is less than or equal to the height of the door, we can proceed as follows:

Let's say the height of the glass is h feet. Then, we know that the glass is a rectangular shape with dimensions of 8 feet by h feet. To pass through the door, the glass needs to be able to fit horizontally and vertically through the opening.

Since the door is 3 feet wide, the glass needs to be able to fit through the opening when turned on its side. Therefore, the height of the glass cannot exceed 3 feet.

So, the door must be at least 3 feet tall for the glass to pass through. However, this assumes that the height of the glass is less than or equal to 3 feet. If the height of the glass is greater than 3 feet, then the door would need to be taller to accommodate the glass.

To determine the minimum height the door must be for the 8-foot wide glass to pass through the 3-foot wide door, you can use the Pythagorean theorem. The glass will need to be tilted diagonally as it passes through the door. Let's label the door's height as 'h' and use the formula:

3² + h² = 8²

9 + h² = 64

h² = 64 - 9
h² = 55
h = √55

The door must be at least √55 feet tall, which is approximately 7.42 feet, for the 8-foot wide glass to pass through the 3-foot wide door.

To find how many 18-inch pieces of ribbon there are in 1620 inches, simply divide 1620 by 18.

1620/18 = 90

For the original question, we know that each roll of ribbon is 9 feet long. To convert to inches, multiply 9 by 12.

9*12 = 108

Now, to find how many 18-inch pieces of ribbon there are in 108 inches,  divide 108 by 18.

108/18 = 6

Since we have 15 rolls of ribbon, multiply 6 by 15.

6*15 = 90

∴ The dressmaker can cut ninety 18-inch pieces from 15 rolls or ribbon.

Step-by-step explanation:

If a triangle has a right angle (90 degrees), it is called a right triangle. The side opposite the right angle is called the hypotenuse, and it is the longest side of the triangle. The other two sides are called the legs.

To find the length of the third side of a right triangle, we can use the Pythagorean theorem, which states that in a right triangle, the sum of the squares of the two legs is equal to the square of the hypotenuse.

The Pythagorean theorem can be written as:

a^2 + b^2 = c^2

where a and b are the lengths of the two legs, and c is the length of the hypotenuse.

But you already know c, and with that c^2, you want to find a through a^2(you can also look for b, it would be the same)

If you rearrange the equasion you get a^2=c^2-b^

Once we have these lengths

c=15,so c^2 is 15^2=15*15=225

b=10,so b^2 is 10^2=10*10=100

we can plug them into the Pythagorean theorem and solve for the unknown side.

a^2=c^2-b^2

a^2=225-100=1125

If a^2 is 125, then a must be the square route if 125
