What is the measure of arc BEC in circle D? 134° 150 209° 210°.

Answer:

This question is incomplete, the complete question is;

A tube is being stretched while maintaining its cylindrical shape. The height is increasing at the rate of 2 millimeters per second. At the instant that the radius of the tube is 6 millimeters, the volume is increasing at the rate of 96π cubic millimeters per second. Which of the following statements about the surface area of the tube is true at this instant? (The volume V of a cylinder with radius r and height h is V=πr2h. The surface area Sof a cylinder, not including the top and bottom of the cylinder, is S=2πrh.)

A) The surface area is increasing at the rate of 28pi square mm per second.

B) The surface area is decreasing at the rate of 28pi square mm per second.

C) The surface area is increasing at the rate if 32pi square mm per second.

D) The surface area is decreasing at the rate of 32pi square mm per second.

Answer:

Surface Area is increasing at the rate of 28π mm²/sec  ( Option A )

Explanation:

Given the data in the question;

let r be the radius and h be the height of the tube

so volume V = πr²h

dv/dt = πr² dh/dt + 2nrh dr/dt

⇒ 96n = π × 36 × 2 + 2π × 6h dr/dt

⇒ 24π = 12nh dr/dt ⇒ h.dr/dt = 2

Area Surface S = 2nrh

ds/dt = 2π ( r.dh/dt + h.dr/dt )

= 2π ( 6×2 + 2)

= 2π (14)

= 28π

therefore Surface Area is increasing at the rate of 28π mm²/sec ( Option A )

The American Revolution ended in 1783, and the French Revolution began in 1789; however, the French Revolution was more complicated than the American Revolution.

The protest began in response to the British monarchy and Parliament levying taxes without regard for colonial representation.

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

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.

The expression that is equivalent to [(2a⁻³b⁴)²/(3a⁵b)⁻²]⁻¹ is;

1/(36a⁴b¹⁰)

[(2a⁻³b⁴)²/(3a⁵b)⁻²]⁻¹

[(2a⁻³b⁴)² × (3a⁵b)²]⁻¹

Let us simplify (2a⁻³b⁴)² to get;

4b⁸/a⁶

Similarly for (3a⁵b)²;

⇒ 9a¹⁰b²

Thus, we now have;

[(4b⁸/a⁶) × 9a¹⁰b²]⁻¹

Thus; a¹⁰/a⁶ = a⁴

Similarly  b⁸ × b² = b⁽⁸ ⁺ ²⁾ = b¹⁰

[(4b⁸/a⁶) × 9a¹⁰b²]⁻¹ = (36a⁴b¹⁰)⁻¹

Finally, we now have;

Explanation:  

is unobservable

"In the past, behaviorists were not likely to view cognition as a part of learning because cognition is unobservable." Thus, option D is correct.

Thinking, attention, language, learning, memory, and perception are all examples of cognitive activities that occur in the brain. These processes are not distinct talents; rather, they are a collection of interconnected abilities that enable us to function as healthy adults.

Learning, according to behaviorists, takes place mostly through observation. They thought that a person learns different parts of his or her life through observation. Imitation, modeling, and other forms of observation are all part of the observation process. Experiments on classical conditioning were used by behaviorists to illustrate that behavior is a learned process. Cognition, on the other hand, refers to the mental processes that include comprehension and knowledge.

As a result, Previously, behaviorists were unlikely to consider cognition to be a component of learning, since cognition is a mental process. Hence, option D is correct.

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.

The American Civil War, commonly referred to by other names, lasted from April 12, 1861, until May 26, 1865. The Union[f] ("the North") and the Confederacy ("the South"), the latter of which was made up of seceding states, engaged in combat.

The conflict over whether to allow slavery to spread into the western regions, creating more slave states, or to forbid it from doing so, which was widely believed to put slavery on the path to eventual extinction, was the main driver of the war.

Answer:

Explanation:

area ABD = 16*12/2  

area ABC = 9*12/2

------------------------------

so the ratio of the area ABC to the area of ABD = (9*12/2)/(16*12/2) =  

= 9/16  

hope this helped!

mark me brainliest :D

The ratio of the area of ABC to the area of ABD is 9/16. The correct option is B.

The space occupied by any two-dimensional figure in a plane is called the area. The space occupied by the triangle in a two-dimensional plane is called the area of the triangle.

The area of a triangle is the region bounded by its perimeter or its three sides. The area of a triangle can be calculated using the formula, where the base of the triangle is b and the height is h.

A = ½ (b × h)

The two areas will be calculated as:-

Area ABD = ( 1 / 2 )  x 16  x  12

Area ABC = (1 / 2 ) x  9  x  12

So the ratio of the area ABC to the area of ABD will be

= [ ( 1 / 2)  x 16  x  12 ]  ÷  [ (1 / 2 ) x  9  x  12 ]

=  9 / 16

Therefore, the area of ABC to the area of ABD is 9/16. The correct option is B.
