MOTIVATION

Most geometry so far has involved triangles and quadrilaterals, which are formed by intervals on lines, and we turn now to the geometry of circles. Lines and circles are the most elementary figures of geometry − a line is the locus of a point moving in a constant direction, and a circle is the locus of a point moving at a constant distance from some fixed point − and all our constructions are done by drawing lines with a straight edge and circles with compasses. Tangents are introduced in this module, and later tangents become the basis of differentiation in calculus.

The theorems of circle geometry are not intuitively obvious to the student, in fact most people are quite surprised by the results when they first see them. They clearly need to be proven carefully, and the cleverness of the methods of proof developed in earlier modules is clearly displayed in this module. The logic becomes more involved − division into cases is often required, and results from different parts of previous geometry modules are often brought together within the one proof. Students traditionally learn a greater respect and appreciation of the methods of mathematics from their study of this imaginative geometric material.

The theoretical importance of circles is reflected in the amazing number and variety of situations in science where circles are used to model physical phenomena. Circles are the first approximation to the orbits of planets and of their moons, to the movement of electrons in an atom, to the motion of a vehicle around a curve in the road, and to the shapes of cyclones and galaxies. Spheres and cylinders are the first approximation of the shape of planets and stars, of the trunks of trees, of an exploding fireball, and of a drop of water, and of manufactured objects such as wires, pipes, ball-bearings, balloons, pies and wheels.

a) The series of transformations to map Circle A onto Circle B is likely a translation. b) The series of transformations to map Circle C onto Circle A is a translation, rotation, and scaling.

a. To map Circle A onto Circle B, we must determine the transformation sequence. We can scale, rotate, and translate.

Translation: An object is translated horizontally or vertically without affecting shape or orientation. To match Circle B, Circle A appears to need to be shifted right and up.

Rotation: An object rotates around a fixed point. Rotation may not be needed since Circle A and Circle B appear to be aligned.

Scaling: An object is resized by scaling. Since Circle A and Circle B are the same size, scaling doesn't seem necessary.

Thus, Circle A-to-Circle B transformations are likely translations.

b. Again, we must determine the transformation sequence to transfer Circle C onto Circle A. Translation: Based on their relative positions, Circle C needs to be shifted left and down to match Circle A.

Rotation: To align Circles A and C, they must be rotated.

Scaling: Circle A is larger than Circle C, hence Circle C should be scaled down.

Thus, translating, rotating, and scaling map Circle C onto Circle A.

s=t+ 5 45 + 2t = 110​

Answers

The amount of ribbon needed for a square poster will be 20.

And, The amount of ribbon needed for a triangular poster will be 15.

What is an expression?

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Given that;

The system of equation are;

⇒ s = t + 5

⇒ 45 + 2t = 110​

Now,

Since, The system of equation are;

⇒ s = t + 5         ..(i)

⇒ 4s + 2t = 110​  ..(ii)

Solve equation (ii) for t as;

⇒ 45 + 2t = 110​

⇒ 4s + 2t - 4s = 110​ - 4s

⇒ 2t = 110 - 4s

⇒ t = 55 - 2s

Substitute above value in equation (i), we get;

⇒ s = t + 5  

⇒ s = 55 - 2s + 5  

⇒ s + 2s = 60

⇒ 3s = 60

⇒ s = 20

And,   ⇒ t = 55 - 2s

⇒ t = 55 - 2 x 20

⇒ t = 55 - 40

⇒ t = 15

Thus, The amount of ribbon needed for a square poster will be 20.

And, The amount of ribbon needed for a triangular poster will be 15.

The graph of which function has an amplitude of 3 and a right phase shift of ?

Answers

Answer:

The first one

Step-by-step explanation:

The amplitude is usually the first number (for example, in this equation, the 3). Then you also know that the right or left shift depends on the addition or subtraction sign. Usually, the subtraction sign means to the right and the addition sign means to the left.

We have that the graph of which function has an amplitude of 3 and a right phase shift of [tex]\phi= \frac{\pi}{4}[/tex]  is

[tex]3sin2(x+\phi)[/tex]

The Correct option is D

From the Question we are told that

A graph has

Amplitude of 3

Phase [tex]\phi= \frac{\pi}{4}[/tex]

Generally the equation for the Wave Equation  is mathematically given as

[tex]Asin(kx-wt+\phi)[/tex]

Therefore the Equation for this particular wave is

[tex]3sin2(x+\phi)[/tex]

Hence

The graph of which function has an amplitude of 3 and a right phase shift of [tex]\phi= \frac{\pi}{4}[/tex]  is

73 divided by the difference between 12 and 7


Answers

Answer:

14.6

Step-by-step explanation:

difference: 12-7=5

division: 73/5=14.6

The 73 divided by the difference between 12 and 7 is equal to 14.6.

To properly calculate 73 divided by the difference between 12 and 7, we follow these steps:

Calculate the difference between 12 and 7:

12 - 7 = 5

Divide 73 by the difference obtained:

73 ÷ 5 = 14.6

Therefore, 73 divided by the difference between 12 and 7 is equal to 14.6. This means that if we take the value 73 and divide it by the difference between 12 and 7, the quotient will be 14.6. The difference between 12 and 7 is 5, and when we divide 73 by 5, we obtain 14.6. It is important to note that the result is a decimal value, specifically 14.6.

plz help meee i will give brainliest if correct ABCD is a square. If m PLEASE HELP!!!!adapted from The Expansion of the United Statesfrom A Short History of the Worldby H.G. Wells The region of the world that displayed the most immediate and striking results from the new inventions in transport was North America. Politically, the United States embodied, and its constitution crystallized, the liberal ideas of the mid-eighteenth century. It dispensed with state-church or crown, it would have no titles, it protected property jealously as a method of freedom, and it gave nearly every adult male citizen a vote. Its method of voting was crude, and therefore its political life soon fell, but that did not prevent the newly emancipated population from developing an energy, enterprise, and public spirit far beyond that of any other contemporary population. Then came that acceleration of locomotion. It is a curious thing that America, which owes most to this acceleration in locomotion, has felt it least. The United States has taken the railway, the river steamboat, the telegraph, and so forth as though they were a natural part of their growth. They were not. These things happened to come along just in time to save American unity. The United States of today was made first by the river steamboat, and then by the railway. Without these things, the present United States would have been altogether impossible. The westward flow of population would have been far more sluggish. It might never have crossed the great central plains. The first state established beyond the river was the steamboat state of Missouri in 1821. But the rest of the distance to the Pacific was done in a few decades. If we had the resources then, it would be interesting to show a map of North America year by year from 1600 onward, with little dots to represent hundreds of people, each dot a hundred, and stars to represent cities of a hundred thousand people. For two hundred years, the reader would see the little dots creeping slowly along the coastal districts and navigable waters, spreading still more gradually into Indiana, Kentucky, and so forth. Then somewhere about 1810 would come a change. Things would get more lively along the river courses. The dots would be multiplying and spreading. That would be the steamboat. Then from about 1850 onward would come the black lines of the railways, and after that the little black dots would not simply creep but run. Then suddenly here and then there would appear the first stars to indicate the first great cities of a hundred thousand people. First one or two and then a multitude of citieseach like a knot in the growing net of the railways. The growth of the United States is a process that has no precedent in the world's history; it is a new kind of occurrence. Such a community could not have come into existence before, and if it had, without railways it would certainly have dropped to pieces long before now. Without railways or telegraph, it would be far easier to administer California from Pekin than from Washington. But this great population of the United States of America has not only grown outrageously; it has kept uniform. Nay, it has become more uniform. The man of San Francisco is more like the man of New York today than the man of Virginia was like the man of New England a century ago. The United States is being woven by railway, by telegraph, more and more into one vast unity, speaking, thinking, and acting harmoniously with itself.
