15.1 central angles and inscribed angles homework answers

Answers

Answer 1

The central and inscribed angle theorem is used to solve angles and arc measure in a circle.

What is the Central and Inscribed Angles Theorem?

The theorem shows the relationship of the measures of an inscribed angle, central angle, and their intercepted arc.

It states that:

central angle measure = measure of inscribed angle.inscribed angle measure = 1/2(measure of inscribed angle)

Therefore, the central and inscribed angle theorem is used to solve angles and arc measure in a circle.

12.3 geometric series evaluate homework and practice

Answers

The geometric series would have a uniform common ratio

The recursive definition of the geometric sequence is [tex]a_n = 4a_{n-1}[/tex] where a1 = 128

How to determine the geometric series?

Assume the geometric sequence is given as:

128,32,8,2

And the question requires the recursive definition of the geometric series

Start by calculating the common ratio (r)

[tex]r = \frac{a_{n}}{a_{n-1}}[/tex]

Substitute 2 for n

[tex]r = \frac{a_2}{a_1}[/tex]

Substitute known values

[tex]r = \frac{128}{32}[/tex]

Evaluate the quotient

[tex]r = 4[/tex]

Substitute 4 for r in [tex]r = \frac{a_{n}}{a_{n-1}}[/tex]

[tex]4 = \frac{a_{n}}{a_{n-1}}[/tex]

Cross multiply

[tex]a_n = 4a_{n-1}[/tex]

Hence, the recursive definition of the geometric series is [tex]a_n = 4a_{n-1}[/tex] where a1 = 128

drag the labels to identify the events in the generation of an action potential in order and correctly name the refractory periods.

Answers

An absolute refractory period occurs during depolarization while the relative refractory period takes place during repolarization.

What is an action potential?

An action potential refers to a sudden, quick change in electrical potential (voltage) during the transmission of an impulse (signal) to a receptor, across a cellular membrane.

The order of events in the generation of an action potential include the following:

At -60 mV, graded depolarization transmits an area of excitable membrane to threshold.At +30 mV, voltage-gated sodium channels are opened for sodium ions to move into the cell. As repolarization begins, sodium channels close, voltage-gated potassium channels are opened for potassium ions to move out of the cell. Finally, both sodium and potassium channels return to their normal states as the potassium channels is closed.

In conclusion, an absolute refractory period occurs during depolarization while the relative refractory period takes place during repolarization.

9-5 skills practice solving quadratic equations by completing the square

An example of 9-5 practice question on quadratic equations by completing the square is   5x2–2x−9=0.

What are  quadratic equation?

This is known to be a type of  algebraic expression that is based on the second degree in x. The quadratic equation often exist in a standard form such as  ax2 + bx + c = 0.

To solve for   5x2–2x−9=0

Then you have to rearrange the equation into:

x2−(2/5)x−9/5=0

= x2−(2/5)x=9/5

= (x−(2/10))2−(2/5)2=9/5(here b = 2/5)

= (x−(2/10))2=46/25

Then you take the square root on both sides

= (x−(2/10))=±1.356

Each of the following statements is arguably true of thermometers. Which of them is most helpful to keep in mind if you are conducting an experiment to measure the specific heat of a material?

Answers

The statement that is true of thermometers is; The temperature reported by a thermometer is never precisely the same as its surroundings.

What is the function of thermometer in an experiment?

In the experiment to determine the specific heat of a material, the theory will be one which explains that when a heat interchange takes place between two bodies that were having different temperatures at the beginning, the quantity of heat the warmer body looses is equal to that gained by the cooler body to reach the equilibrium temperature. This is true only if no heat is lost or gained from the surrounding.

Now, If heat is gained or lost from the surrounding environment, the temperature readings by the thermometer will be incorrect. The experimenter should therefore have in mind that for accurate results, the temperature recorded by the thermometer is similar to that of the surrounding at the beginning of the experiment and if it differs then note that  heat is either gained or lost to the environment.

When the 0.10 m solution of hclo2 is allowed to come to equilibrium, what percent of the acid molecules are ionized?

Answers

If 0.10 m solution of hclo2 is allowed to come to equilibrium, the percent of the acid molecules that is ionized is 29%

We have

HClO2 = 0.1 mole = 0.012

HClO + H2O ⇄ ClO₂⁻ + H₂O

Ka = 0.1α x 0.1α / 0.1(1-α)

= 0.1α²/1-α = 0.12

We have to form a quadratic equation from the above

0.1α² = 0.012 - 0.12α

We write the equation to be

0.1α² + 0.012 - 0.12α = 0

To solve the equation above, the quadratic formula calculator was used.

[tex]\frac{-b+-\sqrt{b^2-4ac} }{2}[/tex]

alpha = 0.29

This is 29 percent. Therefore the percentage of ionization is 29%.
