The measure of angle COA will be 160°. Option C is correct. Center angle theorem is the base of the given problem.

What is the definition of geometry?

It is concerned with the geometry, region, and density of various 2D and 3D shapes.

The measure of an angle formed by an arc of a circle with any point on the circumference of that circle is half the angle formed by that arc at the center of the circle.

The angle formed by arc AC at the center, will be twice as large. Therefore,

∠AOC = 2∠ABC

∠AOC = 2(80°)

∠AOC = 160°

As a result, the center angle AOC is 160 degrees.

Read the excerpt from "A Modest Proposal. " Whereas the maintainance of an hundred thousand children, from two years old, and upwards, cannot be computed at less than ten shillings a piece per annum, the nation's stock will be thereby encreased fifty thousand pounds per annum, besides the profit of a new dish, introduced to the tables of all gentlemen of fortune in the kingdom, who have any refinement in taste. And the money will circulate among our selves, the goods being entirely of our own growth and manufacture. Which sentence best paraphrases the excerpt? England will save a great deal of money because they will not have to maintain the cost of raising poor children. The money will circulate amongst themselves. Swift states that wealthy gentlemen with good taste will now have a new dish to buy and consume at mealtimes. Swift argues that caring for thousands of children will cost more than ten shillings a piece each year. His proposal to eat the children would increase the circulation of money by fifty thousand pounds yearly and strengthen England’s economy. Breeding, selling, and eating impoverished children will benefit the people of England in more than one way.

Swift argues that caring for thousands of children will cost more than ten shillings a piece each year. His proposal to eat the children would increase the circulation of money by fifty thousand pounds yearly and strengthen England’s economy.

What is Economy?

A complex system of linked trading, consumption, and production activities makes up an economy, and it ultimately decides how resources are distributed among all the players.

The requirements of persons who live and work inside the economy are met by the creation, consumption, and distribution of products and services.

A country, a region, a single industry, or even a family may be represented by an economy. An economy is a collection of interconnected production and consumption processes that ultimately decide how resources are distributed within a community.

Therefore, Swift argues that caring for thousands of children will cost more than ten shillings a piece each year. His proposal to eat the children would increase the circulation of money by fifty thousand pounds yearly and strengthen England’s economy.

A desert is very hot during the day and receives very little rain. Which plants will likely survive in this kind of environment?.

Answers

Explanation:

A cactus is a plant that would survive

A desert is very hot during the day and receives very little rain. The plants that will likely survive in this kind of environment are plants with waxy coatings. Thus the correct option is A.

What is the environment?

The environment is referred to as the surroundings where all living and nonliving things are present. The environment contains different types which include the atmosphere, hydrosphere, lithosphere, and biosphere.

Desert is referred as dryland which constitutes more than one-fifth of the planet's landmass and can be found on every continent. These regions experience a "moisture imbalance," which indicates that they typically lose more moisture to drainage.

The gravity of the waxy substance on their leaves, floating plants, which have short branches, would sink underwater if not for the weight of the leaves. The plant is shielded from hazards outside by the waxy layer, which also holds moisture.

Therefore, option A is appropriate.

Answer:

Correct answer is C) $14.200.39

Explanation:

we know that

The simple interest formula is equal to

I = Prt

P = I / (rt)

where

I is the amount of money in interest

P is the Principal amount of money to be invested

r is the rate of interest  in decimal

t is Number of Time Periods

in this problem we have

t = 9 years  

I = $5,896

P = ?

r = 0.0692

substitute in the formula above  

P = 5,896/ (0.0692 ÷ 6) = $14,200.39

Answers

Colleges use ACT scores as a key factor in the admission process, scholarship, placement and eligibility


Describing the ways to use ACT scores

Admission: Colleges use ACT scores as a key factor in the admission process. Many colleges have a minimum ACT score requirement for admission, and students who score below the minimum may not be accepted. The score also helps admissions officers evaluate applicants and determine their academic preparedness for college.

Scholarship awards: Many colleges offer scholarships based on ACT scores. Students who score high on the ACT may be eligible for more scholarship money, which can help offset the cost of tuition.

Placement: Colleges use ACT scores to place students in appropriate courses. Students who score well on the ACT may be able to bypass introductory courses and enroll in higher-level courses, while students who score lower may need to take remedial courses to build foundational knowledge.

Program eligibility: Some programs at colleges have specific ACT score requirements for admission. For example, students who want to enter a pre-med or engineering program may need a minimum ACT score to be considered for admission. The score also helps determine eligibility for honors programs or other specialized programs within the college.

What is the total kinetic energy of a 0. 15 kg hockey puck sliding at 0. 5 m/s and rotating about its center at 8. 4 rad/s? the diameter of the hockey puck is 0. 076 m.

Answers

The mass of the puck is

m = 0.15 kg.

The diameter of the puck is 0.076 m, therefore its radius  is

r = 0.076/2 = 0.038 m

The sliding speed is

v = 0.5 m/s

The angular velocity is

ω = 8.4 rad/s

The rotational moment of inertia of the puck is

I = (mr²)/2

 = 0.5*(0.15 kg)*(0.038 m)²

 = 1.083 x 10⁻⁴ kg-m²

The kinetic energy of the puck is the sum of the translational and rotational kinetic energy.

The translational KE is

KE₁ = (1/2)*m*v²

      = 0.5*(0.15 kg)*(0.5 m/s)²

      = 0.0187 j

The rotational KE is

KE₂ = (1/2)*I*ω²

      = 0.5*(1.083 x 10⁻⁴ kg-m²)*(8.4 rad/s)²

      = 0.0038 J

The total KE is

KE = 0.0187 + 0.0038 = 0.0226 J

Answer: 0.0226 J

The options that are true about regression with one predictor variable include:

A. The slope describes the amount of change in Y for a one-unit increase in XB. The regression equation is the line that best fits a set of data as determined by having the least squared error.

Regression simply refers to a statistical measurement which attempts to determine the strength that exists between a dependent variable and the independent variables.

It should be noted that in one predictor variable, the slope describes the amount of change in Y for a one-unit increase in X and the regression equation is the line that best fits a set of data as determined by having the least squared error.

Therefore, the correct answers are A and B.
