Is the square root of a negative number a real number?.

Answer:

32.9 cm^2

Step-by-step explanation:

In the absence of a diagram, lets use the one shown in the attached worksheet.  The assumption is that the "blue areas" are the four sections of the circle that extend beyond the square boundaries.  The approach is to calculate areas for both the circle and the square.

Square = (11 cm)^2              =  121 cm^2

Circle = (3.14)*(14/2 cm)^2  =   153,9 cm^2

Subtract the square from the circle.  That removes all the circle area, except for the four sections outside the square.  The result is 32.9 cm^2

Answer:

Domain:

[tex] - \infty < x < \infty [/tex]

Range:

[tex] - 1 \le \: y < \infty [/tex]

Step-by-step explanation:

The Domain of a function is x values which are included in the graph. Sometimes x values will not be included because they cannot be defined at that point, but in this case the graph indicates that the graph continues to the right and left with no indication that there is an asymptote or it is undefined beyond the graph so we can assume it's defined for all real numbers. We can represent this in interval notation as:

[tex] - \infty < x < \infty [/tex]

Since if you plug in any real number, this inequality should be true.

The range of a function is defined as y values which are on the graph, this is restricted when certain y values are not on the graph... but we can usually tell because functions will have a minimum/maximum. By looking at the graph it appears to reach a minimum at y = -1 and then on the right and left side is increasing, never going below this value, so the range can be defined as:

[tex] - 1 \le y < \infty [/tex]

Since the y values vary between -1 (including -1) and infinity... well that really just means there's no upper bound and it just keeps increasing and increasing.

An inequality that shows how much faster Elanor can drive without going over the speed limit is 43.5 + s ≤ 55.

Elanor can increase her speed by 2.

In order to write and solve an inequality that represents how much faster Elanor can drive without going over the speed limit, we would take note of the following important information;

Now, we can write an inequality that represents the value of s for which the speed of Elanor is still safe as follows;

43.5 + s ≤ 55

By subtracting 43.5 from both sides of the inequality, we have the following:

43.5 - 43.5 + s ≤ 55 - 43.5

s ≤ 11.5

The axis of symmetry is the y-axis and the vertex for the function

f(x) = 3(x - 2)²+ 4 is (2,4).

Given f(x) = 3(x - 2)² + 4

The graph will be symmetrical to the y-axis and since a> 0, the parabola opens up.

The axis of symmetry is the line that divides a parabola into two symmetrical parts. The vertex is the point where the axis of symmetry intersects the parabola.

The axis of the symmetry is x=2

The vertex form of a parabola is y = a (x - h)²+ k

The vertex is given by (h,k) coordinates.

In order to find the vertex, we need to compare the given equation to the vertex form of the parabola.

f(x) = 3(x - 2)²+ 4=0

a = 3, h = 2 and k = 4

Thus the vertex of the function is (2,4).

No, 0 is neither an infinite solution nor no solution.

The solution x = 0 implies that the value 0 satisfies the equation, so there is a solution. “No solution” implies that there is no value, not even 0, which would satisfy the given equation.

Let us take an example for a more reasonable interpretation,

An example is the equations

A full rotation, or a complete revolution, is 360 degrees. Therefore, an angle of 360 degrees is called a "full rotation" or a "complete revolution." It is also sometimes called a "congruent" angle.

A full rotation is known as a circle. A circle is a round-shaped figure that has no corners or edges.

In geometry, a circle can be defined as a closed, two-dimensional curved shape.

The entire circle completes a total of 360 degrees as it completes one rotation or what we call a complete revolution.

The value that will 8(-4x+3) equivalent to -14x+ _+(18x) is 24

Equivalent expressions are expressions that work the same even though they look different. If two algebraic expressions are equivalent, then the two expressions have the same value when we plug in the same value(s) for the variable(s).

for example 2+ 3 and 4 + 1 are equivalent. The both have a value of 5.

Similarly;

8(-4x+3) , when the parentheses is opened, = -32x +24

Answer:

40%

Step-by-step explanation:

There are 5 options to roll: 1, 2, 3, 4, and 5.

This means you have a 1 out of 5 chance of rolling each number.

This question is asking for 1 AND 2, not just one number. So, we have a 2 out of 5 chance of rolling that, because 2 options are acceptable instead of just one number.

I'm not sure which form you are looking for, but 2 out of 5 is the same as saying 2/5. Most probability solutions are wanted as a percentage. To find that just solve 2/5, which is 0.4. Move the decimal to the right twice, and that is a 40% chance.

An algebraic expression with more than 03 terms is known as Multinomial.

Multinomial Distribution:

In probability theory, the multinomial distribution is a generalization of the binomial distribution. For example, model the probability of counting on each side of a k-sided die n tosses. For n independent trials, each succeeds in exactly one of the k categories, and each category has a certain fixed probability of success. A multinomial distribution gives the probability for each particular combination of numbers of successes in different categories.

If k is 2 and n is 1, the multinomial distribution is Bernoulli. If k is 2 and n is greater than 1, the distribution is binomial. If k is greater than 2 and n is 1, the distribution is categorical. The term "multinoulli" is sometimes used for categorical distributions to emphasize this four-way relationship (hence n determines the prefix and k determines the suffix).

The adult tickets sold were 409.

11a + 3c = 3520

Where "a" is the number of adult tickets sold and "c" is the number of child tickets sold.

We also know that the theater sold a total of 464 tickets, so we can add the following equation:

a + c = 464

We can now use the first equation to solve for one of the variables, and then substitute it into the second equation:

11a + 3c = 3520

3c = 3520 - 11a

c = (3520 - 11a)/3

We know that:

a + c = 464

We can substitute the value of c into this equation:

a + (3520 - 11a)/3 = 464

a + (3520 - 11a) = 464*3

a + 3520 - 11a = 1392

12a = 4912

a = 4912/12

The next three terms in the sequence are 79, 90, and 101.

a) To find a formula for the sequence, we can use a difference table.

First, let's write out the first few terms of the sequence:

3, 14, 32, 60, 98, ...

Next, we'll create a difference table:

n | Term | Difference

1 | 3 |

2 | 14 | 11

3 | 32 | 18

4 | 60 | 28

5 | 98 | 38

We see that the difference is increasing by 10 each time, so our formula can be written as:

Term = 11n + 3

To check the formula, we can plug in a few values of n and see if it matches the terms in the sequence:

n = 1, Term = 11(1) + 3 = 14

n = 2, Term = 11(2) + 3 = 32

n = 3, Term = 11(3) + 3 = 60

The formula matches the terms in the sequence, so it is correct.

b) To find the next three terms in the sequence, we can use our formula:

n = 6, Term = 11(6) + 3 = 79

n = 7, Term = 11(7) + 3 = 90

n = 8, Term = 11(8) + 3 = 101

Given that the line includes the point (6,4) and has a slope of -1/10, we can substitute these values into the point-slope form to get the equation of the line:

To calculate the speed of the car's tires turning, you need to first calculate the circumference of the tire. If the tire has a 25 inch diameter, multiply 25 by 3.1416 to find the tire circumference, which is 78.54 inches. Now, divide 63,360 inches per mile by the tire circumference (78.54) to find the revolutions per mile, which is 803.6. Finally, multiply 803.6 by 29 (the speed of the car in mph) to get the revolutions per minute, which is 23,253.6. Therefore, the car's tires are turning at a rate of 23,253.6 revolutions per minute.
