Consider the given equation [tex]x^2-8x+14=0[/tex]

We will solve this equation by completing the square method.

Consider the coefficient of 'x', divide it by '2'. then adding and subtracting the square of this number in the given equation.

Coefficient of 'x' = -8

By dividing it by '2', we get -4

Taking the square of '-4' = 16

Adding and subtracting '16' from the given equation.

[tex]x^2-8x+14+16-16=0[/tex]

So, [tex]x^2-8x+16 = -14+16[/tex]

This equation shows one of the step used in solving the equation by completing the square method.

Therefore, option 1 is the correct answer.

For Jamal to solve the equation, [tex]x^2 - 8x + 14 = 0[/tex], by completing the square, one of the steps that could be taken is: A. [tex]\mathbf{x^2 - 8x + 16 = - 14 + 16}[/tex]

Jamal was given the equation, [tex]x^2 - 8x + 14 = 0[/tex], to solve by completing the square.

To do this, the first step would be to move the constant, 14 to the other side of the equation by subtracting 14 from both sides of the equation.

[tex]x^2 - 8x + 14 - 14 = 0 -14\\\\x^2 - 8x = -14[/tex]

The next step to take is for Jamal to add the square of half of the coefficient of x to both sides of the equation.

[tex]x^2 - 8x + 16 = - 14 + 16[/tex] (this tallies with the first option given).

Therefore, for Jamal to solve the equation, [tex]x^2 - 8x + 14 = 0[/tex], by completing the square, one of the steps that could be taken is: A. [tex]\mathbf{x^2 - 8x + 16 = - 14 + 16}[/tex]

Answer:

Refer answer below

Step-by-step explanation:

Given is a graph in the interval (-infinity, infinity).

From the graph we observe that it is continuous graph.

The curve is decreasing for x <-2 and increases for (-2,1) and again decreases from (1,3) then increases from (3,infinity)

Hence f'(x) >0 for (-2,1) and (3,infinity)

f'(x) <0 for (-infty, -2) and (1,3)

From the above we find that f'(x) =0 for x=-2,1,and 3

Extreme points are -2,1 and 3

Absolute and local minima at x=-2, y=-9.67

Local maxima at (1,6.08) and again

local minima at (3,0.75)

Absolute maxima  lies at infinity

Answer:

 Option 4. overall minimum in (-2.9.67)

Step-by-step explanation:

A global maximum point (x0, f (x0)) is defined as the point at which f (x0) is the maximum value of the function. That is, there is no value in the domain of f (x) other than x0 where f (x) is greater than f (x0)

A global minimum point (x0, f (x0)) is defined as the point at which f (x0) is the smallest value of the function. That is, there is no value in the domain of f (x) other than x0 where f (x) is less than f (x0)

Based on that deficion we must look for the point where f (x) has the lowest value.

That point is (-2.9.67)

Therefore that is the overall minimum of the function.

Although the function has a maximum in (1.6.08), the function keeps growing for x> 4, that means that there is a point where the function is bigger than in x = 1.

Therefore this is not a local maximum.

100p-5p^2 = 0

Factor out 5p out of 100p and -5p^2:

5p(20) + 5p(-p) = 0

5p(20-p)=0

Divide each term by 5:

p = 0

Set 20-p to 0 and solve for p:

p = 20

There can be 24 unique four-digit numbers formed from the numerals 7, 6, 5, and 3, calculated by the factorial of 4 (4!).

The student asks how many four-digit numbers can be made from the numerals 7, 6, 5, and 3. These numbers can be arranged in a systematic way, and the total number of combinations can be calculated using permutations. The formula to calculate permutations without repetition is n! (n-factorial), where 'n' is the number of numerals to arrange.

In this case, we have 4 numerals, so the calculation would be 4! This equals to 4 × 3 × 2 × 1 = 24. Thus, there are 24 unique combinations when we arrange the numerals 7, 6, 5, and 3 into four-digit numbers without any repetitions.

The probability that at least one of the three randomly selected internet users is more careful about personal information when using a public wi-fi hotspot is 97.3%.

To find the probability that at least one of the three randomly selected internet users is more careful about personal information when using a public wi-fi hotspot, we can calculate the probability of the complement event, which is the event that none of the users are more careful. Since the probability that an internet user is more careful is 70%, the probability that a user is not more careful is 1 - 70% = 30%. The probability of the complement event for all three users is (0.3)^3 = 0.027. Therefore, the probability that at least one user is more careful is 1 - 0.027 = 0.973, or 97.3%.

Additional information that the survey subjects volunteered to respond does not affect the calculation of the probability. The probability is based solely on the given percentage from the poll, which represents the proportion of internet users who are more careful about personal information when using a public wi-fi hotspot.

The probability that at least one internet user is more careful about personal information when using a public wi-fi hotspot is 0.973.

To find the probability that at least one person is more careful about personal information when using a public​ wi-fi hotspot, we can use the complement rule. The complement of at least one person being more careful is that no one is more careful. So, the probability that no one is more careful is 0.3 multiplied by 0.3 multiplied by 0.3 (since there are three internet users). Then we subtract this probability from 1 to find the probability that at least one person is more careful. So, the probability that at least one person is more careful is 1 - (0.3 x 0.3 x 0.3) = 0.973.

The additional information that the survey subjects volunteered to respond does not affect the result of the probability calculation. The probabilities are based on the initial survey results, and any additional information would be separate from those probabilities.

12x + 6y = 24

add -6 to both side

12x + 6y + -6y = 24 + -6y

Combine like terms:

6y + -6y = 0

12x + 0 = 24 + -6y

12x = 24 + -6y

Divide each side by '12'

x = 2 + -0.5y (your answer)

Answer:

you minus 8 from 20 which will = to 12. Then you divide 12 by 4.99 and it equals to like 2.4 but you can't buy a .4 of a candy bar so have to round it down to 2

Step-by-step explanation:

Janelle can buy 2 snacks with her remaining budget after purchasing a movie ticket. The inequality 20 ">= 8" + 4.99x is satisfied with x=2, where each snack costs $4.99.

Janelle is at the movie theater with a budget of $20 to spend. After purchasing her movie ticket for $8, she wants to buy snacks with the remaining money. Since each snack costs $4.99, we can represent the situation with the following inequality:

20 ≥ 8 + 4.99x

To find out how many snacks, x, Janelle can buy, we subtract the cost of the movie ticket from her total budget:

$20 - $8 = $12

Now, we divide the remaining amount by the cost of one snack:

$12 / $4.99 ≈ 2.4

Since Janelle cannot buy a fraction of a snack, we round down to the nearest whole number. Thus, Janelle can buy 2 snacks with her remaining budget.

Answer:

[tex]x < 17.89[/tex] or [tex]x > 18.61[/tex] , since [tex]\left | x-18.25 \right |>0.36[/tex]

Step-by-step explanation:

According to the question the weight is rejected if it is more than 0.36 oz, the weight should not be beyond 0.36 oz that is from the target weight of 18.25.  

We can say that, the difference between the actual weight and the target weight is greater than 0.36 oz.

Lets say the actual weight is 'x'. So,

[tex]x-18.25>0.36[/tex]

But there can be times when the actual weight 'x' could be less than 0.36, So the order will be changed:

[tex]18.25-x>0.36[/tex]

The absolute value will sum up these two into a single inequality:

[tex]|x-18.25|>0.36[/tex]

Simplifying the inequalities, we get:

[tex]x-18.25>0.36[/tex]

[tex]x>18.61[/tex]   (we have added 18.25 on both sides)

 [tex]18.25-x>0.36[/tex]

Subtracting 18.25 from both the sides we get:

[tex]-x>-17.89[/tex]

After sign change it is:

[tex]x<17.89[/tex]

So we can see that only [tex]x < 17.89[/tex] or [tex]x>18.61[/tex] since [tex]\left | x-18.25 \right |>0.36[/tex] is the one that represents the scenario given above.

You can represent the unknown amounts by the use of variables. Follow whatever the description is and convert it one by one mathematically.

For example if it is asked to increase some item by 4 , then you can add 4 in that item to increase it by 4. If something is for example, doubled, then you can multiply that thing by 2 and  methods can be used to convert description to mathematical expressions.

We have to find the variable expression represents the phrase '25 decreased by the sum of 6 and a number'
