express x^2 - 8x + 5 in the form (x - a)^2 - b where a and b are integers

Answers

Answer:

x^2 -8x + 5 = (x-4)^2 - 11

Step-by-step explanation:

Here we want to write the given expression in the form

x^2-8x + 5 can be written as follows;

(x-4)^2 = x^2 - 8x + 16

All we have to do is to subtract 11

Thus, we have it that;

x^2-8x + 5 = (x-4)^2 - 11

Prove De Morgan's law by showing that each side is a subset of the other side by considering x ∈ A⎯⎯⎯ A ¯ ∩ B⎯⎯⎯ B ¯ .

Answers

Solution :

We have to prove that [tex]$\overline{A \cup B} = \overline{A} \cap \overline{B}$[/tex]   (De-Morgan's law)

Let  [tex]$x \in \bar{A} \cap \bar{B}, $[/tex] then [tex]$x \in \bar{A}$[/tex] and [tex]$x \in \bar{B} $[/tex]

and so [tex]$x \notin \bar{A}$[/tex] and [tex]$x \notin \bar{B} $[/tex].

Thus, [tex]$x \notin A \cup B$[/tex] and so [tex]$x \in \overline{A \cup B}$[/tex]

Hence, [tex]$\bar{A} \cap \bar{B} \subset \overline{A \cup B}$[/tex]   .........(1)

Now we will show that [tex]$\overline{A \cup B} \subset \overline{A} \cap \overline{B}$[/tex]

Let [tex]$x \in \overline{A \cup B}$[/tex] ⇒ [tex]$x \notin A \cup B$[/tex]

Thus x is present neither in the set A nor in the set B, so by definition of the union of the sets, by definition of the complement.

[tex]$x \in \overline{A}$[/tex] and  [tex]$x \in \overline{B}$[/tex]

Therefore, [tex]$x \in \overline{A} \cap \overline{B}$[/tex] and we have [tex]$\overline{A \cup B} \subset \overline{A} \cap \overline{B}$[/tex]  .............(2)

From (1) and (2),

[tex]$\overline{A \cup B} = \overline{A} \cap \overline{B}$[/tex]

Hence proved.

A coin is flipped 10 times and lands on heads 8 times. The theoretical probability that the next coin flip will be heads is 50%.


True or False

Answers

True

Even though it landed on heads 8/10 times, ther's still a 50% chance that it will land on tails. It doesn't change the percentage of it landing on either side. So in that case, it is true.

Hope this helps!

The statement, A coin is flipped 10 times and lands on heads 8 times. The theoretical probability that the next coin flip will be heads is 50% is True.

What is probability?

The probability of an occurrence is a figure that represents how likely it is that the event will take place. In terms of percentage notation, it is expressed as a number between 0 and 1, or between 0% and 100%.

here, we have,

we know that,

The higher the likelihood, the more likely it is that the event will take place. A definite occurrence has a chance of 1 while an impossible event has a probability of 0.

we have,

When a coin is flipped the probability of getting a heads and a tail is 50%.

Hence, without the consideration of the flips and the result the theoretical probability that the next coin flip will be heads is 50%.

The statement, A coin is flipped 10 times and lands on heads 8 times. The theoretical probability that the next coin flip will be heads is 50% is True.

Fifty students were eating lunch in the school cafeteria. The ratio of boys to girls was 25:25. Mrs. White asked Kym to explain what that ratio meant. Kym said it meant that 25% of the students in the cafeteria were boys.


Explain why Kym is incorrect.

Answers

Answer:

Kym is wrong because instead of 25% it would be 50 percent

Step-by-step explanation:

Answer:

Sample Response: The ratio of boys to total students was 25:50. Written as a fraction, this is 25/50. Rewrite the fraction with a denominator of 100 to 50/100. So 50% of the students were boys.

Answers

Answer:

2a²

Step-by-step explanation:

Pair 'like' terms with 'like' terms, ie numbers go with numbers, and 'a's go with 'a's.

Lets deal with the top of the fraction first:

4ax3a³

Rearrange it so you have numbers beside numbers and 'a's beside 'a's:

(4x3)x(axa³)

12x(a⁴) (because nᵃxnᵇ=nᵃ⁺ᵇ)

12a⁴

Now, instead of (4ax3a³)/6a², we have 12a⁴/6a²

First divide the numbers: 12/6 =2

Now divide the 'a' parts: a⁴/a²=a² (because nᵃ/nᵇ=nᵃ⁻ᵇ)

Now we have 2a²

If using the method of completing the square to solve the quadratic equation
22 + 15x – 11 = 0, which number would have to be added to "complete the
square"?

Answers

Answer:

Step-by-step explanation:

Let's solve your equation step-by-step.

22+15x−11=0

Step 1: Simplify both sides of the equation.

22+15x−11=0

22+15x+−11=0

(15x)+(22+−11)=0(Combine Like Terms)

15x+11=0

15x+11=0

Step 2: Subtract 11 from both sides.

15x+11−11=0−11

15x=−11

Step 3: Divide both sides by 15.

15x

A sea turtle descends 28 feet from the surface of the ocean and then ascends 5 feet. Then it descends 9 feet and repeats this descent 4 times. How many feet below the surface is the turtle then ?

Answers

Answer: 59 feet

Step-by-step explanation:

First the sea turtle descended 28 feet.

It then ascends 5 feet which means it is now:

= 28 - 5

= 23 feet below surface

It then descends 9 feet and repeats that descent 4 time:

= 9 * 4

= 36 feet below the surface

Total distance below the surface:

= 23 + 36

= 59 feet
