Answers

Answer 1

The quadratic equations, or the equations that are quadratic in form, for this problem is given as follows:

6(2x + 4)² = 2x + 4 + 2.x^4 - 6x² - 27 = 0.6x^4 = -x² + 5.

What is a quadratic equation?

The degree of a function is given by the highest exponent that appears in the definition of the function.

A quadratic function is a function that has a degree of 2.

The standard format of a quadratic function is given as follows:

y = ax² + bx + c.

(in which the coefficient a must assume a value different of zero).

The quadratic function in this problem is given as follows:

6(2x + 4)² = 2x + 4 + 2.

As (2x + 4)² = 4x² + 16x + 16, meaning that the highest exponent would be of 2.

However, equations of the fourth degree can also be quadratic in form, as long as the exponents go as follows: 4, 2 and 0.

Hence these following equations are also quadratic in form:

x^4 - 6x² - 27 = 0.6x^4 = -x² + 5.

They are classified as quadratic in form because a transformation such as y = x² can make them quadratic.

Answers

Answer:

EF is 109

DAB is 54.5

Step-by-step explanation:

Applying the central angle theorem, the correct statement would be:

Measure of minor arc EF = 109°Measure of angle DAB = 54.5°

What is the Central Angle Theorems?

The central angle theorem states that:

Measure of intercepted arc = 1/2(measure of inscribed angle)Measure of central angle = measure of intercepted arc

Thus:

Measure of minor arc EF = m∠ECF = 109°

m∠DAB = 1/2(109°) [m∠ECF = m∠BAD = 109°]

m∠DAB = 54.5°

Therefore, applying the central angle theorem, the correct statement would be:

Measure of minor arc EF = 109°Measure of angle DAB = 54.5°

Exercise 5.16.1: Coin flips and events. About A coin is flipped four times. For each of the events described below, express the event as a set in roster notation. Each outcome is written as a string of length 4 from {H, T}, such as HHTH. Assuming the coin is a fair coin, give the probability of each event. (a) The first and last flips come up heads. Solution (b) There are at least two consecutive flips that come up heads.

Answers

Answer:

[tex](a)\ Pr = 0.25[/tex]

[tex](b)\ Pr = 0.50[/tex]

Step-by-step explanation:

Given

[tex]Flips = 4[/tex]

First, we calculate the sample size;

The coin has two possible outcomes (i.e. head or tail) and the number of flips is 4.

So, the sample size (N) is:

[tex]N = 2^4[/tex]

[tex]N = 16[/tex]

Solving (a): Probability the outcome of the first and last flip is head.

The possible outcomes for this event are:

[tex]n = \{(HHHH), (HHTH), (HTHH),(HTTH)\}[/tex]

[tex]n(n) = 4[/tex]

The probability is:

[tex]Pr = \frac{n(n)}{N}[/tex]

[tex]Pr = \frac{4}{16}[/tex]

[tex]Pr = 0.25[/tex]

 

Solving (a): Probability that the outcome of at least 2 consecutive flips is head.

The possible outcomes for this event are:

[tex]n = \{(HHHH), (HHHT),(HHTH), (HTHH),(THHH),(TTHH),(HHTT), (THHT)\}[/tex]

[tex]n(n) = 8[/tex]

The probability is:

[tex]Pr = \frac{n(n)}{N}[/tex]

[tex]Pr = \frac{8}{16}[/tex]

[tex]Pr = 0.50[/tex]
