What is the 325th Triangular number?

Answers

Answer:52813

Step-by-step explanation:

To get the 325th triangular number all you have to do is n x (n+1) /2

N=325

325 x 325+1

325x325=105625

105625+1=105626

Then, you find that t = 4 hours. That that means that he spent 2.5 hours driving back. Then, we can do d=vt and find 90/2.5 as the speed he went home at. Which comes out to be 36 mph.

An equilateral triangle with side lengths of 8.7 centimeters is shown. An apothem has a length of a and the radius has a length of 5 centimeters. The apothem and radius form a triangle with a base length of b. Which statements about finding the area of the equilateral triangle are true? Select three options

Answers

The image of the triangle is missing, so i have attached it.

Also, the options are;

A) The apothem can be found using the Pythagorean theorem.

B) The apothem can be found using the tangent ratio.

C) The perimeter of the equilateral triangle is 15 cm.

D) The length of the apothem is approximately 2.5 cm.

E) The area of the equilateral triangle is approximately 65 cm².

Answer:

Options A, B & D are true

Step-by-step explanation:

A) We are told that the triangle is an equilateral triangle.

Thus, the 3 sides equal 8.7 cm.

Now from the image, b is half of one of the sides.

Thus, b = 8.7/2 = 4.35 cm

Now, we want to find the apothem "a".

Using Pythagoras theorem, we have;

a² + 4.35² = 5²

a² = 25 - 18.9225

a² = 6.0775

a = √6.0775

a ≈ 2.5 cm.

Thus, option A is true as pythagoras theorem was able to calculate the apothem "a"

B) since the main triangle is equilateral, it means each angle is 60°.

Now,the radius line from one corner point to the centre will divide the 60° angle into 2 equal parts.

Thus, the angle made by the radius line with the base of the triangle is 60/2 = 30°

Now,from tangent ratios, we know that;

Opposite/Adjacent = tan θ

In the small triangle, opposite is apothem "a" while adjacent is b = 4.35 cm

Thus;

a/4.35 = tan 30

a = 4.35 tan 30

a ≈ 2.5 cm.

Thus, option B is correct as Tangent ratio can be used to find the apothem

C) The perimeter of equilateral triangle = 3x

Where x is length of one side.

One side is 8.7 cm

Thus, perimeter = 3 × 8.7 = 26.1 cm

Thus option C is not correct.

D) From calculations above, we saw that in both options A & B, the apothem is approximately 2.5 cm.

Thus, option D is true.

E) Area of triangle is;

A = ½ × base × height

Base = 8.7 cm

To get height, we will use trigonometric ratio. Thus;

h/8.7 = sin 60°

h = 8.7 sin 60°

Thus;

A = ½ × 8.7 × 8.7 sin 60°

A = 32.77 cm²

Thus is not equal to 65 cm². Thus, option E is not correct.

Answers

Answer:

The real answer is -17, do the math.

Step-by-step explanation:

28 - 45= -17

28 + 17 = 45

45 - 28 = 17

Plsssss helppppp y-27 greater than or equal to -13

Answers

Answer:

y-27 >= -13

Step-by-step explanation

you are finding y, so you will leave the y and convert the 27 into a positive 27.

y >= -13 + 27

Once that is done, simplify.

-13+27 = 14

so your answer will be:

y>14

Given point Q (2,5), which of the following points is NOT 5 units away from point Q?

A(-2,2)
B(5, 1)
C (3,2)
D(-1, 1)

Answers

Answer;

C ; (3,2)

Explanations;

Mathematically, the equation of the distance between two points can be given as;

D^2 = (y2-y1)^2 + (x2-x1)^2

The distance we are dealing with is 25

Mathematically, the square of 3 and the square of 4 added together gives 25

So the coordinates that will be our answer will be such coordinates that will not give 3 and 4 for either of x or y axes

Looking at it;

Let’s work with the first option;

D^2 = (5-2)^2 + (2-(-2))^2

D^2 =3^2 + 4^2

We can see that this works

Second option;

D^2 = (5-1)^2 + (2-5)^2

D^2 = 4^2 + (-3)^2

Since (-3)^2 is same as 3^2, this option works too

Third option

D^2 = (5-2)^2 + (2-3)^2

D^2 = (3)^2 + (-1)^2

We can see that the sum here won’t give 25 , so this is our answer

Which statement represents the parallel postulate in Euclidean geometry, but not elliptical or spherical geometry?

1 .Through a given point not on a line, there exists no lines parallel to the given line through the given point.

2.Through a given point not on a line, there exists exactly one line parallel to the given line through the given point.

3.Through a given point not on a line, there exists more than one line parallel to the given line through the given point.

4.Through a given point not on a line, there exists exactly three lines parallel to the given line through the given point.

Answers

Answer:

2.Through a given point not on a line, there exists exactly one line parallel to the given line through the given point.

Step-by-step explanation:

The object of "Euclidean geometry" (more commonly called "plane geometry") is, in principle, the study of the shapes and properties of natural bodies. However, geometry is not an experimental science since its object is not to study certain aspects of nature but a necessarily arbitrary reproduction of it.

After the definitions, Euclid then poses his famous postulates (his requests), the fifth of which has remained Euclid's postulate, often called axiom (or postulate) of parallels and which was the subject of much research and controversy as to its necessity:

Given two points A and B, there exists a line passing through A and B. Any segment [AB] can be extended into a straight line passing through A and B. For any point A and any point B distinct from A, we can describe a circle with centre A passing through B. The whole right angles are always equal to each other. By a point outside a line, we can draw a parallel and only one to this line.

From the above explanation, we could deduce that the correct option is Option 2.

Answer:

The answer is B, Through a given point not on a line, there exists exactly one line parallel to the given line through the given point.

Answer: slope intercept is y=mx+b

standard form is Ax+By=C.

point slope form is y-y₁=m(x-x₁)

so y=2/3x+2 is slope intercept

Answer:

+Slope-intercept is... y=mx+b

+The standard form is... Ax+By=C.

+A point-slope form is... y-y₁=m(x-x₁)

Answers

Answer:

Step-by-step explanation:

8.5*6.2=52.7

The required time taken by Denise to complete the race is 52.7 minutes.

Given that,
Denise runs a 10-kilometer race (6.2 miles). Her average time per mile is 8.5 minutes per mile.

What is speed?

Speed is defined as when an object is subjected to move, the distance covered by the object in a certain time interval is the speed of that object.

What is simplification?

The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.

Here,
Denise runs a 10-kilometer race (6.2 miles).
Denise run 1 mile in 8.5 minutes
Time is taken by denis to run 6.2 miles =  6.2 * 8.5
                                                                  = 52.7 minutes

Thus, the required time taken by Denise to complete the race is 52.7 minutes.

But then came the question of how to count a states population. Women would count toward population, the founders decided, even though women couldn't vote. The next question the founders tackled: should they count slaves?The Southern states wanted slaves to count toward their populations. They had more slaves, so counting them toward population would mean that they could send more representatives to the House. The more populated states in the North didn't want slaves to count toward the population of the Southern states. They didnt have as many slaves and didnt want to lose the advantage of having larger populations. Ultimately the delegates agreed on a seemingly random fraction: in determining a states population, each slave would count as three-fifths of a person.
