A triangle is a three-sided polygon with three angles, each angle is formed by the intersection of two sides of the triangle and these angles are labeled with the corresponding vertex.

There are three angles in a triangle ABC. A triangle is a three-sided polygon and it has three angles. Each angle is formed by the intersection of two sides of the triangle.

In a triangle, the angle between two sides is measured in degrees and these angles are formed by the intersection of the two lines that represent the sides of the triangle. The three angles in a triangle are labeled with the corresponding vertex, for example, angle A, angle B, and angle C.

In a triangle, the sum of the three angles is always 180 degrees. This can be proved using the fact that a straight line is 180 degrees. If we draw a straight line, and divide it into two angles, which are supplementary angles. Therefore, these angles add up to 180 degrees. In a triangle, we can draw one straight line and divide it into three angles, which are supplementary angles, therefore the sum of the angles in a triangle is always 180 degrees.

Therefore, In short, a triangle is a three-sided polygon with three angles, each angle is formed by the intersection of two sides of the triangle and these angles are labeled with the corresponding vertex. The sum of the three angles in a triangle is always 180 degrees.

The number of earth days that it will take the planet to orbit the star is 500 earth days.

The rate of distance moved in a specific direction to the time taken can be referred to as the speed.

i.e speed = distance/ time taken

In the given question, the total distance covered is the length of the orbit.

So that,

length of the orbit = 2πR

where R is the radius i.e the distance of the star to the planet.

length of the orbit = 2 * 3.142 * 67000000

                              = 421028000 km

speed = distance/ time taken

⇒     time taken = distance/ speed

                          = 421028000 km/ 35,000 km/h

                          = 12029.37 h

But,

1 earth day = 24 hours

x = 12029.37 h

x = 12029.37 h * 1 earth day/ 24 h

  = 501.2238 earth days

The number of earth days it will take the planet to orbit the star is 500 earth days.

The angle 5 is an acute angle.

The correct answer is an option (a)

We know that the most common types of angles (based on their magnitude) are:

Acute Angle,

Obtuse Angle, (an angle which is less that 180° and greater than 90°)

and Right Angle (an angle that measures 90°)

There are some types of angle based on their rotation:    

Straight Angle, (an angle measuring 180 degrees)

Reflex Angle, (an angle which is greater than 180 degrees but less than 360 degrees )

What is a function?

A function is defined as a relation between a set of inputs having one output each. In simple words, a function is a relationship between inputs where each input is related to exactly one output. Every function has a domain and co-domain or range. A function is generally denoted by f(x) where x is the input. The general representation of a function is y = f(x).

There are several types of functions in math. Some important types are:

Injective function or One to one function: When there is mapping for a range for each domain between two sets.

Surjective functions or Onto function: When there is more than one element mapped from domain to range.

Polynomial function: The function which consists of polynomials.

Inverse Functions: The function which can invert another function.

Now,

Initial numbers, 100 Zombies and 100 Vampires.

In function z(t), the zombies increase in population by 1000 per day,

and in function V(t), the vampire population increases by 25% each day,

Therefore, z(t)=100+1000t where t=no, of days and

v(t)=100+25t where t= no. of days

for z(t)=50000

100+1000t=50000

t=49900/1000=49.9≈50days

for v(t)=50000

100+25t=50000

t=49900/25=1996 days

We showed that EFGH is a square by proving that EFGH is a rhombus and all the angles are right angles. This is one of the classic proofs of the Pythagorean theorem.

(a) First, explain why the EFGH must be a rhombus.

In the figure, square ABCD has points E, F, G, and H on each side, so AE = BF = CG = DH, as shown. This means that all four sides of the rectangle EFGH are the same length. This is because they are all congruent with the side lengths of square ABCD. According to the definition of a rhombus, a rhombus is a quadrilateral with all four sides congruent. All four sides of the quadrilateral EFGH are congruent, so it must be a rhombus.

(b) Explain why all interior angles in EFGH must be right angles?

In square ABCD, by definition, all interior angles are right angles (90 degrees). Since the points E, F, G, and H lie on the sides of the square ABCD, the angles EFG and FGH are congruent to the right angle of the square ABCD. Similarly, the angles FGH and HGE are congruent to the right angle of the square ABCD.

Therefore, all four interior angles of quadrilateral EFGH are congruent with right angles of square ABCD, and all four interior angles of quadrilateral EFGH are right angles.

A square is a quadrilateral with all four sides congruent and all four angles congruent at right angles. And since it has already been proved that the quadrilateral EFGH is a rhombus and all its angles are right angles, we know that the quadrilateral EFGH is a square.

Using Composition of functions, the value of g(h(24)) = 1158.

A function is composed in mathematics when two functions, f and g, are used to create a new function, h, such that h(x) = g(f(x)). The function of g is being applied to the function of x, in this case. Therefore, a function is essentially applied to the output of another function.

The new function h is created by combining the two functions f and g, where h(x) = f(g(x)) for all x in g's domain where g(x) is in f's domain. Function composition is denoted by the notation h = f • g, also written as h(x) = (f • g)(x), which can be interpreted as "f of g of x."

Given,

g(x) = 2x + 4, h(x) = x² +1

Using composition of functions,

⇒ h(24) = 24² + 1

⇒ g(h(24)) = 2 (24² + 1) + 4

Answer:

The length of the shorter leg of the triangle can be calculated using the Pythagorean Theorem. The formula is a^2 + b^2 = c^2, where a is the length of the shorter leg, b is the length of the longer leg and c is the length of the hypotenuse. In this case, a^2 + 52^2 = c^2. The hypotenuse can be calculated by using the sine formula. c = (52/sinA). Substituting this value into the Pythagorean Theorem equation, a^2 + 52^2 = (52/sinA)^2. Solving for a, a = sqrt(52^2 - (52/sinA)^2).

The area of the Temasa's doll house is 31.5 square feet.

What is the scale factor?

The scale factor is a ratio that compares the measurements of an object on a drawing or map to the actual measurements of that same object in real life. It is usually expressed as a ratio in the format 1:n (or 1/n) where n is the scale factor.

We can start by using the scale factor of 1:10 to find the actual dimensions of the doll house.

Since the scale factor is 1:10, this means that for every 1 inch on the drawing, the actual measurement is 10 inches. So, to find the actual length and width of the doll house, we can multiply the measurements on the drawing by 10.

7 1/5 inches * 10 = 71 inches + 2 inches

4 4/5 inches * 10 = 44 inches + 8 inches

So, the actual length of the doll house is 71 inches + 2 inches = 73 inches, and the actual width is 44 inches + 8 inches = 52 inches.

To find the area of the doll house, we can multiply the length and width:

73 inches * 52 inches = 3788 square inches

To convert this to square feet, we can divide by 12^2, since 1 foot = 12 inches:

3788 square inches / (12 inches)^2 = 31.5 square feet (rounded to the nearest square foot)

Hence, the area of the Temasa's doll house is 31.5 square feet.
