Step-by-step explanation:

For quadratic ax^2 +bx +c, the vertex is located at ...

  x = -b/(2a)

For your quadratic, this is ...

  x = -(-6)/(2(3)) = 1

The y-value at that point is ...

  y = 3(1^2) -6(1) +12 = 3 -6 +12 = 9

The vertex is (x, y) = (1, 9).

What is a mixed number?

Mixed numbers can be written either way, for example, 5 and 3/4 or 534. The mixed number's fractional component needs to be a legal fraction (less than one whole). In a correct fraction, such as 37 or 1115, the numerator (top number) is smaller than the denominator (bottom number).

\($$4 \frac{1}{3} \times 6$$\)

Convert mixed numbers to improper fractions: \($4 \frac{1}{3}=\frac{13}{3}$$$\)

\(=\frac{13}{3} \times 6$$\)

Convert element to fraction: \($6=\frac{6}{1}$$$\)

\(=\frac{13}{3} \times \frac{6}{1}$$\)

Apply the fraction rule: \($\frac{a}{b} \times \frac{c}{d}=\frac{a \times c}{b \times d}$$$\)

\(=\frac{13 \times 6}{3 \times 1}$$\)

Multiply the numbers: \($3 \times 1=3$$$\)

\(=\frac{13 \times 6}{3}$$\)

Divide the numbers: \($\frac{6}{3}=2$$$=13 \times 2$$\)

Multiply the numbers: \($13 \times 2=26$$$=26$$\)

B) - A mixed number in the answer boxes is \(=8 \frac{2}{3}\)

\($$2 \frac{3}{5} \times 3 \frac{1}{3}$$\)

Convert mixed numbers to improper fractions: \($2 \frac{3}{5}=\frac{13}{5}$$$=\frac{13}{5} \times 3 \frac{1}{3}$$\)

Convert mixed numbers to improper fractions: \($\quad 3 \frac{1}{3}=\frac{10}{3}$$$\)

\(=\frac{13}{5} \times \frac{10}{3}$$\)

Apply the fraction rule: \($\frac{a}{b} \times \frac{c}{d}=\frac{a \times c}{b \times d}$$$=\frac{13 \times 10}{5 \times 3}$$\)

Factor the number: \($10=5 \times 2$$$=\frac{13 \times 5 \times 2}{5 \times 3}$$\)

Answer:

x=45

Step-by-step explanation:

We know that x+30 is equal to 75 because they are vertical and are the same angle

x+30=75

Subtract 30 from both sides

x=45

Hey there! :)

Answer:

m∠x = 45°.

Step-by-step explanation:

To solve for x:

x + 30° = 75° because they are Alternate Interior angles. This means that the two angles are congruent.

Solve for x:

x + 30° = 75°

Subtract 30 from both sides:

x = 45°.

The other two angle measures of a right triangle with side lengths 5, 12, and 13 can be found using trigonometric ratios. Let's label the sides of the triangle as follows:

- The side opposite the angle we are looking for is 5.
- The side adjacent to the angle we are looking for is 12.
- The hypotenuse is 13.

To find the first angle, we will use the inverse tangent function (tan^(-1)). The formula is:
Angle = tan^(-1)(opposite/adjacent)

Plugging in the values, we get:
Angle = tan^(-1)(5/12)

Using a calculator, we find this angle to be approximately 22.6 degrees (rounded to the nearest degree).

To find the second angle, we will use the fact that the sum of the angles in a triangle is 180 degrees. Therefore, the second angle can be found by subtracting the right angle (90 degrees) and the first angle from 180 degrees.
Second angle = 180 - 90 - 22.6

Calculating this, we find the second angle to be approximately 67.4 degrees (rounded to the nearest degree).

Therefore, the other two angle measures of the right triangle are approximately 23 degrees and 67 degrees.

Mean

Mean is the average of the given numbers and is calculated by dividing the sum of given numbers by the total number of numbers.

Standard deviation

Recall

The local maximum and local minimum value of function f(x) = 1 + 9x^2 − 6x^3 is  4 and  1.

To find the local maximum and minimum values of the function f(x) = 1 + 9x^2 - 6x^3 using the First Derivative Test, we need to follow these steps:

   Find the derivative of f(x).

   Set the derivative equal to zero to find critical points.

   Determine the intervals where the derivative is positive or negative.

   Use the First Derivative Test to classify the critical points as local maximum or minimum points.

Let's proceed with these steps:

   Finding the derivative of f(x):

   f'(x) = d/dx (1 + 9x^2 - 6x^3)

   = 0 + 18x - 18x^2

   = 18x - 18x^2

   Setting the derivative equal to zero and solving for critical points:

   18x - 18x^2 = 0

   18x(1 - x) = 0

Setting each factor equal to zero:

18x = 0 --> x = 0

1 - x = 0 --> x = 1

So, we have two critical points: x = 0 and x = 1.

   Determining the intervals where the derivative is positive or negative:

   To determine the sign of f'(x) in each interval, we can test some sample points within those intervals:

For x < 0: Let's test x = -1.

f'(-1) = 18(-1) - 18(-1)^2 = -18 - 18(1) = -36

For 0 < x < 1: Let's test x = 0.5.

f'(0.5) = 18(0.5) - 18(0.5)^2 = 9 - 4.5 = 4.5

For x > 1: Let's test x = 2.

f'(2) = 18(2) - 18(2)^2 = 36 - 72 = -36

Based on these sample calculations, we can determine the sign of f'(x) as follows:

For x < 0: f'(x) < 0

For 0 < x < 1: f'(x) > 0

For x > 1: f'(x) < 0

   Using the First Derivative Test:

   Since f'(x) changes from negative to positive at x = 0, we can conclude that there is a local minimum at x = 0.

Since f'(x) changes from positive to negative at x = 1, we can conclude that there is a local maximum at x = 1.

Therefore, the local maximum value of f(x) is f(1) and the local minimum value of f(x) is f(0).

Substituting these x-values into the function f(x), we can find the corresponding y-coordinates:

f(1) = 1 + 9(1)^2 - 6(1)^3 = 1 + 9 - 6 = 4

f(0) = 1 + 9(0)^2 - 6(0)^3 = 1 + 0 - 0 = 1

Hence, the local maximum value is 4, and the local minimum value is 1.

The complement of set A is { 3, 6, 13, 14, 17, 19}

The complement of a set is the set that includes all the elements of the universal set that are not present in the given set. Let's say A is a set of all coins which is a subset of a universal set that contains all coins and notes, so the complement of set A is a set of notes (which do not includes coins).

U = {2,3,6,9,10,13,14,17,19}, A =  {2,9,10}

set A complement are all the elements in the Universal set U not contained in set A. Those elements are in set A' =  { 3, 6, 13, 14, 17, 19}

The optimal values of these parameters are:

a. β₁ = 0

b. β₂ = 0

The linear regression y = β1 + β2x + e, assuming that the sum of squared errors (SSE) takes the following form:

SSE = 382 + 681 + 382 + 18β1β2

Derive the partial derivatives of SSE with respect to β1 and β2 and solve the optimal values of these parameters.

Given that SSE = 382 + 681 + 382 + 18β1β2 ∂SSE/∂β1 = 0 ∂SSE/∂β2 = 0

Now, we need to find the partial derivative of SSE with respect to β1.

∂SSE/∂β1 = 0 + 0 + 0 + 18β2 ⇒ 18β2 = 0 ⇒ β2 = 0

Therefore, we obtain the optimal value of β2 as 0.

Now, we need to find the partial derivative of SSE with respect to β2. ∂SSE/∂β2 = 0 + 0 + 0 + 18β1 ⇒ 18β1 = 0 ⇒ β1 = 0

Therefore, we obtain the optimal value of β1 as 0. Hence, the partial derivative of SSE with respect to β1 is 18β2 and the partial derivative of SSE with respect to β2 is 18β1.

Thus, the optimal values of β1 and β2 are 0 and 0, respectively.

Therefore, the answers are: a. β₁ = 0 b. β₂ = 0

Answer:

The rate is 15 minutes per meter.

Step-by-step explanation:

It takes 9 minutes to fill a depth of  meters.

Filling   meters take 9 minutes time.

Filling 3 meters of the aquarium takes  = 45 minutes time (Multiplying by 5 both the numbers).

In order to fill 1 meter of the aquarium it will take  minutes (Dividing by 3 both the numerical values).

===================================================

Work Shown:

8 minutes = (2/5) meters

5*(8 minutes) = 5*( (2/5) meters )

40 minutes = 2 meters

40/2 minutes = 2/2 meters

20 minutes = 1 meter

The unit rate in minutes per meter is 20 minutes per meter.

In other words, it takes 20 minutes to raise the level 1 meter.

There are a total of 720 permutations of the letters in the word "peppermint".

To calculate this, we use the formula n!/(r! * (n-r)!) where n is the number of objects (in this case, letters) and r is the number of objects chosen from that set. In this case, n = 10 (10 letters in "peppermint") and r = 10 (all 10 letters are chosen).

So, 10!/(10! * (10-10)!) = 10!/(10! * 0!) = 10!/(10!) = 1, which simplifies to 1. That means that there is one way to choose all 10 letters from the word "peppermint", so the total number of permutations is 1 * 10! = 10! = 3628800, or 720.

PLEASE YOUR ART IS SO FREAKIN COOOOLLL

Step-by-step explanation:

Ten gave the check of $5768 to the bank for payment.

Simple interest is calculated based on a loan's principal or the initial deposit into a savings account. Simple interest doesn't compound, so a borrower will never have to pay interest on the interest already accumulated because a creditor will only pay interest on the principal amount.

Formula for simple interest is;-

Simple interest = (principal amount×rate of interest×time duration in years)/100

S.I = (P×R×T)/100

Calculation of the total amount paid by Ted to the bank-

The principal amount is  $5,600.

The rate of interest is 9%.

Time duration is 4 months equals 4/12 = 1/3 years.

S.I = (5,600×9×1)/(3×100)

S.I  = 168

The simple interest on amount is $168.

Thus, the total amount is S.I + principal amount

Total amount = 168 + 5600

                      = 5768

Therefore, the total amount paid by the Ted to the bank is $5768.
