the step function f of x is graphed what is the value of f of 0?​

Answer:

x is equal to -34/16

Step-by-step explanation:

Hey there!

In order to solve for x, we need to first simplify everything

After simplifying, it will look like this:

\((4x^2+14x+16)-7x+14=4x^2-4-9x\)

Now you can simplify by combining like terms

\(4x^2+7x+30=4x^2-9x-4\)

You can cross out \(4x^2\) from both sides and then simplify even more by again combining like terms

\(16x+34=0\\16x=-34\\x=-34/16\)

So x is equal to -34/16

To solve the given equation, let's simplify and expand both sides:

\(\displaystyle\sf (2x+1)(2x+6)-7(x-2)=4(x+1)(x-1)-9x\)

Expanding the brackets:

\(\displaystyle\sf (4x^{2}+13x+6)-7x+14=4(x^{2}-1)-9x\)

Simplifying further:

\(\displaystyle\sf 4x^{2}+13x+6-7x+14=4x^{2}-4-9x\)

Combining like terms:

\(\displaystyle\sf 4x^{2}+6x+20=4x^{2}-9x-4\)

Subtracting \(\displaystyle\sf 4x^{2}\) from both sides:

\(\displaystyle\sf 6x+20=-9x-4\)

Bringing all the variables to one side and the constants to the other side:

\(\displaystyle\sf 6x+9x=-4-20\)

\(\displaystyle\sf 15x=-24\)

Dividing both sides by \(\displaystyle\sf 15\) to solve for \(\displaystyle\sf x\):

\(\displaystyle\sf x=-\frac{24}{15}\)

Simplifying the fraction:

\(\displaystyle\sf x=-\frac{8}{5}\)

Therefore, the solution to the equation is \(\displaystyle\sf x=-\frac{8}{5}\).

(3xy³ + 5x²y⁴)  (3xy³ - 5x²y⁴)

Step-by-step explanation:

Factorize polynomials:

Use exponent law:

                   \(\boxed{\bf a^{m*n}=(a^m)^n} \ & \\\\\boxed{\bf a^m * b^m = (a*b)^m}\)

9x²y⁶ = 3²* x² * y³*² = 3² * x² * (y³)² = (3xy³)²

25x⁴y⁸ = 5² * x²*² * y⁴*² = 5² * (x²)² * (y⁴)² = (5x²y⁴)²

Now use the identity:  a² - b² = (a +b) (a -b)

Here, a = 3xy³ & b = 5x²y⁴

9x²y⁶ - 25x⁴y⁸ = 3²x²(y³)² - 5²(x²)² (y⁴)²

                       = (3xy³)² - (5x²y⁴)²

                      = (3xy³ + 5x²y⁴)  (3xy³ - 5x²y⁴)

Answer:

1 cm and 18 cm

2 cm and 9 cm

3 cm and 6 cm

Step-by-step explanation:

We need to find the factors of 18
which are; 1,18; 2,9; 3,6
So therefore we'd pick:
1 cm and 18 cm

2 cm and 9 cm

3 cm and 6 cm

Answer:

9.18%

Step-by-step explanation:

The probability of getting a tail on a fair coin flip is 0.5, and the probability of getting a head is also 0.5. Since each coin flip is independent, we can use the binomial probability formula to calculate the probability of getting exactly 5 tails in 15 flips:

P(X = 5) = (15 choose 5) * (0.5)^5 * (0.5)^(15-5)

where (15 choose 5) is the number of ways to choose 5 tails out of 15 flips, which can be calculated as:

(15 choose 5) = 15! / (5! * 10!) = 3003

Substituting the values, we get:

P(X = 5) = 3003 * (0.5)^15 ≈ 0.0918

Therefore, the probability of getting exactly 5 tails in 15 coin flips is approximately 0.0918 or 9.18%.

The two numbers are 11, and 5 if the one number is six less than a second number.

A number is a mathematical entity that can be used to count, measure, or name things. For example, 1, 2, 56, etc. are the numbers.

It is given that:

One number is six less than a second number.

Let the number be x and y:

x - 6 =  y

Twice the first is 2 more than 4 times a second.

2x = 2 + 4y

After solving the two linear equations:

2x = 2 + 4(x - 6)

2x = 2 + 4x - 24

2x = 22

x = 11

y = 5

Thus, the two numbers are 11, and 5 if the one number is six less than a second number.

Lower limit of 95% confidence interval is  0.464 and upper limit of 95% confidence interval is 0.594

What is Z value of 95% confidence interval and how to find 95% confidence interval?

A Z value is a numerical measure of how far is an individual score is from the mean score, within a normal distribution.

The Z value for 95% confidence interval is Z=1.96.

Let p the  estimated proportion of people in favor of a proposition and n be the sample size, n = 225

Marginal error = \(Z\sqrt{\frac{p(1-p)}{n} }\)

Lower limit of 95% confidence interval = Z - Marignal error           

Upper limit of 95% confidence interval = Z + Marginal error

Given that in a poll of 225 randomly selected U.S. adults, 119 said they favored a new proposition,

The estimated proportion of people favored a new proposition is, p =\(\frac{119}{225}\)

Then, p = 0.529

Marginal Error = \(Z\sqrt{\frac{p(1-p)}{n} } = 1.960\sqrt{\frac{0.529(1-0.529)}{225} }\) = 0.065

Therefore,

Lower limit of 95% confidence interval   =0.529-0.065  = 0.464    

Upper limit of 95% confidence interval = 0.529+0.065 = 0.594

And the 95% confidence interval would be given (0.464,0.594).

Answer:

It grows 221 centimeters in 13 weeks.

Step-by-step explanation:

Each meter has 100 centimeters.

A coral reef grows 0.17 m every week

So it grows 0.17*100 = 17 cm every week.

How much does it grow in 13 weeks?

17 cm every week for 13 weeks, so

17*13 = 221

It grows 221 centimeters in 13 weeks.

The length of the field is greater than the width by the expression \((14x - 3x^2 + 2y) - (5x - 7x^2 + 7y).\)

1. The length of the field is represented by the expression \(14x - 3x^2 + 2y.\)

2. The width of the field is represented by the expression \(5x - 7x^2 + 7y\).

3. To find the difference between the length and width, we subtract the width from the length: (\(14x - 3x^2 + 2y) - (5x - 7x^2 + 7y\)).

4. Simplifying the expression, we remove the parentheses: \(14x - 3x^2 + 2y - 5x + 7x^2 - 7y.\)

5. Combining like terms, we group the \(x^2\) terms together and the x terms together: \(-3x^2 + 7x^2 + 14x - 5x + 2y - 7y.\)

6. Simplifying further, we add the coefficients of like terms:\((7x^2 - 3x^2) + (14x - 5x) + (2y - 7y).\)

7. The simplified expression becomes: \(4x^2 + 9x - 5y.\)

8. Therefore, the length of the field is greater than the width by the expression \(4x^2 + 9x - 5y.\)

The possible values for a third quiz score that would give her an average between 85 and 90, inclusive is: 97 ≤ x ≤ 112.

In Mathematics, the average of these quiz scores can be calculated by using the following formula:

Average = Sum of quiz score/Number of quiz scores

Note: Let the variable q represent the student's score on the third (3rd) quiz.

Substituting the given parameters into the formula, we have the following;

Average = (75 + 83 + q)/3

Average = (158 + q)/3

This ultimately implies that, an average between 85 and 90, inclusive is given by this compound inequality:

85 ≤ (158 + q)/3 ≤ 90

Multiplying all through by 3, we have the following:

255 ≤ (158 + q) ≤ 270

Subtracting 158 from both sides of the inequality, we have the following:

97 ≤ x ≤ 112

Decentralization is a management approach that involves the delegation and assignment of decision-making rights from top levels of management to lower levels of management. Option A

It is an effective way to empower employees and to improve decision-making processes within an organization. The benefits of decentralization include the following:

It empowers more employees at lower levels of management: Decentralization allows employees to take ownership of their work, to be more accountable, and to make decisions that are in the best interest of the organization. This, in turn, leads to improved job satisfaction, employee engagement, and better overall performance.

It allows for better and more timely decision-making: Decentralization ensures that decisions are made closer to where the work is being done. This leads to faster decision-making, improved responsiveness to changes in the market, and better coordination between different departments and teams.

It trains future managers: Decentralization provides employees with the opportunity to gain valuable management experience, which can help prepare them for future leadership roles within the organization.

However, one benefit of decentralization that is not accurate is that it forces top levels of management to focus on individual units. In fact, decentralization can free up top management to focus on the big picture and long-term strategy, rather than getting bogged down in day-to-day operations.

In conclusion, decentralization is a useful management approach that can help organizations improve decision-making, empower employees, and train future managers.

By delegating decision-making rights to lower levels of management, organizations can improve overall performance and become more adaptable to changes in the market.

So Option A is correct.

Now we must determine whether or not this issue has exponents, which it does. As mentioned in the response box on the lesson's main page.
