Answer:

\((x-4)^{2} +6\)

Step-by-step explanation:

The global maximum occurs at x = -∞ and the global minimum occurs at x = ∞.

Since the function is continuous and has exactly one critical point, this critical point must be either a global maximum or a global minimum. Let's call this critical point "c".

If c is a global maximum, then the function must be decreasing to the left of c and increasing to the right of c. If c is a global minimum, then the function must be increasing to the left of c and decreasing to the right of c.

However, we are given that the interval is undefined for x = 0 and x = 2, which means that the critical point "c" must lie outside of this interval.

Therefore, the global maximum and minimum must occur at the endpoints of the interval. Since the interval is undefined for x = 0 and x = 2, the endpoints are -∞ and ∞.

So the global maximum occurs at x = -∞ and the global minimum occurs at x = ∞.

The terms syllabic, melismatic, and neumatic are all related to the number of notes in relation to each syllable of a text. Syllabic means that each syllable of the text is sung to one note.

This is the simplest type of setting for text to music. In contrast, melismatic means that each syllable of the text is sung to many notes, creating a more intricate and ornamental melody. Neumatic is somewhere in between syllabic and melismatic, where each syllable is sung to a few notes, but not as many as in a melismatic setting.

Syllabic, melismatic, and neumatic all describe the relationship between the number of notes and each syllable of a text.

The surface area of the given prism above would be = 606cm²

To calculate the surface area of the given prism is to add all the area of the faces.

The area of the two triangles = 2(1/2 base×height)

where base = 12 cm

height = 8cm

area = 1/2× 12×8

= 48 × 2 = 96cm²

Area of rectangle =3( l×w )= 3(17×10)

For the function y = 4x^2, it is possible to find the maximum or minimum. the value of y at the maxima/minima of the function y = -3x^2 + 6x is 3.

The function represents a quadratic equation with a positive coefficient (4) in front of the x^2 term. This indicates that the parabola opens upward, which means it has a minimum point.

For the function y = 3x, it is not possible to find the maximum or minimum because it represents a linear equation. Linear equations do not have maxima or minima since they have a constant slope and continue indefinitely.

For the function y = -3x^2 + 6x, we can find the maxima or minima by finding the vertex of the parabola. The vertex can be found using the formula x = -b/(2a), where a and b are coefficients of the quadratic equation.

In this case, the coefficient of x^2 is -3, and the coefficient of x is 6. Plugging these values into the formula, we have:

x = -6 / (2 * -3) = 1

To find the value of y at the vertex, we substitute x = 1 into the equation:

y = -3(1)^2 + 6(1) = -3 + 6 = 3

Therefore, the value of y at the maxima/minima of the function y = -3x^2 + 6x is 3.

Answer:

X = 10

Step-by-step explanation:

Multiply both sides of the equation by 5

x + 2x - 60 = -30

Collect like terms

3x - 60 = -30

Move constant to the right-hand side and change its sign

3x = -30 + 60

Calculate the sum

3x = 30

Divide both sides of the equation by 3

x = 10

Solution

x = 10

Answer: x = 10

Step-by-step explanation:

1/5x + 2/5x - 12 = -6    Add 12 to both sides

The statement is true because the rows of A^T are the columns of (A^T)^T=A(D)

The row space of A^T is spanned by the rows of A, which are also the columns of A^T. Therefore, the row space of A^T is the same as the column space of A.

This can also be seen from the fact that the rank of A^T is equal to the rank of A, and the dimension of the row space and column space of A are both equal to the rank of A. Thus, the statement is true.Therefore the correct answer is option D the statement is true because the rows of A^T are the columns of (A^T)^T=A.

Step-by-step explanation:

Answer:

The number of tickets purchased typically varies from the expected value by 0.95 tickets.

Step-by-step explanation:

The standard deviation of the distribution is 0.95.

The standard deviation in statistics is a measure of the amount of variation or dispersion in a set of values. A low standard deviation implies that the values are close to the set's mean, whereas a high standard deviation shows that the values are spread out over a larger range.

We have

P (X = 1)= 0.29

P (X = 2) = 0.44

P( X= 3) = 0.19

P (X = 4) = 0.06

P (X = 5) = 0.02

The expected value is given by the sum of each value multiplied by it's respective probability, hence:

E(X) = 0.29(1) + 0.44(2) + 0.19(3) + 0.06(4) + 0.02 (5)

E(X) = 2.08

As, The standard deviation is the square root of the total of the difference squared between each value and the mean, multiplied by the likelihood of each value.

\(\sigma\) = √0.29 (1- 2.08)² + 0.44(2- 2.08)² +.....+ 0.02 (5- 2.08)²

  = 0.95

Thus, the standard deviation is 0.95.

there are 4845 different selections of 4 bags of chips that the person can make from the 20 varieties available.

This is a combination question. In combinations, the order of selection does not matter. The person is selecting 4 different bags of chips from a pool of 20 varieties.

To calculate the number of different selections, we can use the formula for combinations:

nCr = n! / (r!(n-r)!)

where n is the total number of items (20 varieties) and r is the number of items to be selected (4 bags of chips).

Plugging in the values, we have:

20C4 = 20! / (4!(20-4)!)

     = 20! / (4!16!)

Simplifying further:

20C4 = (20 * 19 * 18 * 17) / (4 * 3 * 2 * 1)

Answer:

x = 45/2 or 22.5

Step-by-step explanation:

Since we are given CDE ~ KLM, we know that C is similar to K, D is similar to L, and E is similar to M. The problem asks to find DE, so by comparison, it is known that DE is similar to LM.

From the two triangles, KM is similar to CE, and we can see that the ratio between the two is 8:15. We are given LM, which is 12, so we can find x using this equation to compare the smaller triangle to the bigger one:

KM/CE = LM/DE

To add or subtract given  mixed numbers with different denominators we have a few steps to follow:

first, we have to convert the mixed numbers into improper fractions, and then find the common multiple of both denominators.

Next, convert the fractions as common denominators, and solve the fractions, convert the fraction as mixed numbers.

There is another method to add and subtract the mixed numbers:

first, find the Lowest Common Multiple between the denominators, and multiply the numerator and denominator of each fraction by a number so that they have the LCM as their new denominator.

next, add or subtract the numerators and keep the denominator the same.

finally, if the answer is an improper form, reduce the fraction into a mixed number

For this problem, we are given a circle, its radius, and an arc of 120º. We need to calculate the length of the arc.

We need to use the following expression:

Where theta is the angle. We have:

The length of the arc is approximately 16.755 cm.

Step-by-step explanation:

.7071 is the value to convert peak to RMS

The equation of the circle in squared form is \(\rm (x + 6)^2 + (y + 1)^2 = 38\). Then the center of the circle is at (-6, -1).

It is a locus of a point drawn at an equidistant from the center. The distance from the center to the circumference is called the radius of the circle.

The equation of the circle is given as

\(\rm x^{2} + y^2 + 12x +2y - 1 = 0\)

This can be written as

\(\rm x^{2} + y^2 + 12x +2y = 1\)

Add both sides 36 and 1, then

\(\rm x^{2} + 12x + 36 + y^2 +2y +1 = 1 + 36 + 1\)

Then we know that

\(\rm (a+b) ^2 = a^2 + b^2 + 2ab\)

Then

\(\rm (x + 6)^2 + (y + 1)^2 = 38\)

Thus, the center of the circle is at (-6, -1).
