The graph of the first function is y = √(x - 5).

The graph of the second function is y =  |x - 1| + 4.

Suppose we have a function f(x).

f(x) ± d = Vertical upshift/downshift by d units (x, y ±d).

f(x ± c) = Horizontal left/right shift by c units (x - + c, y).

(a)f(x) = Vertical stretch for a > 0, vertical shrink a < 0. (x, ay).

f(bx) = Horizonatal compression b > 0, horizontal stretch for b < 0. (bx , y).

f(-x) = Reflection over y-axis, (-x, y).

-f(x) = Reflection over x-axis, (x, -y).

The graph of the first function is f(x) = y = √x.

Now, f(x - 5) would be the same function shifter 5 units to the right,

f(x) = √(x - 5).

The most appropriate measure for the typical value of the average salary paid to nfl players is mean.

The most appropriate measure for the spread of these salaries is IQR

In statistics, in addition to the mode and median, the mean is one of the measures of central tendency. Simply said, the mean is the average of the values in the given collection. It indicates that values in a certain data collection are distributed equally.

The three most often employed measures of central tendency are the mean, median, and mode. The total values provided in a datasheet must be added, and the sum must be divided by the total number of values in order to get the mean.

The difference between the third and the first quartile is defined by the interquartile range. The partitioned values known as quartiles divide the whole series into four equally sized segments. There are so three quartiles.

The first quartile, also known as the lower quartile, is marked by Q1, the second quartile by Q2, and the third quartile, sometimes known as the upper quartile, is denoted by Q3. The lower quartile less the higher quartile equals the interquartile range.

1/2 ÷ 3 = 1/2 x 1/3 = 1/6

Therefore, one half ÷ 3 is equal to one-sixth.

Answer: The cubic parent function f(x)=x^3 has been transformed to form the function g(x)=-2(x+4)^3-5 in the following ways:

Vertical scaling: The function has been vertically scaled by a factor of -2, which means that the height of the function has been multiplied by -2.

Horizontal shift: The function has been horizontally shifted 4 units to the right. This is because the expression inside the parenthesis (x+4) can be seen as shifting the graph 4 units to the right.

Vertical shift: The function has been vertically shifted down by 5 units. This is because the constant term -5 has been added to the expression, which moves the graph down by 5 units.

So, the parent function f(x)=x^3 has been transformed by a vertical scaling by -2, followed by a horizontal shift 4 units to the right, and finally a vertical shift 5 units down to form the function g(x)=-2(x+4)^3-5.

Answer:

  x ≈ 4.19 meters

Step-by-step explanation:

You want the value of x given a (4x +2) by (2x +3) rectangle with a cutout corner that is (x+2) by (x-1) has an area of 194 square meters.

The difference in area between the enclosing rectangle and the missing corner is ...

  (4x +2)(2x +3) -(x +2)(x -1) = 194

  8x² +16x +6 -(x² +x -2) = 194

  7x² +15x +8 = 194

  7x² +15x -186 = 0 . . . . . . put in standard form

This is best solved using the quadratic formula:

  [tex]x=\dfrac{-b+\sqrt{b^2-4ac}}{2a}=\dfrac{-15+\sqrt{15^2-4(7)(-186)}}{2\cdot7}\\\\=\dfrac{-15+\sqrt{5433}}{14}\approx\boxed{4.193492}[/tex]

Hi there, here's your answer.

Given:

A circle with center O.

A, B, C and D lie on the circumference of the circle.

AC is the diameter of the circle.

∠DCA = 33° and ∠BCA = 31°

To find:

∠DAB

Solution:

Since AC is a diameter, ∠CDA and ∠CBA will be equal to 90° (Angles in a semi-circle)

Now, ∠BCD = ∠DCA + ∠BCA

∴ ∠BCD = 33° + 31° = 64°

Now, ∠BCD + ∠CDA + ∠DAB + ∠ ABC = 360° (Angle-sum property of a quadrilateral)

Substituting the values of the angles:

64° + 90° + 90° + ∠DAB = 360°

Or

244° + ∠DAB = 360°

Therefore ∠DAB = 360° - 244° = 116°

If 6 times the 6th term of an A.P is equal to 9 times the 9th term, then 15th term of the A.P. is -2d with d as the common difference.

Let's call the common difference of the arithmetic progression (A.P.) "d". The nth term of an A.P. is given by the formula T = a + (n - 1)d, where a is the first term and n is the term number.

Using this formula, we can write two expressions for the 6th and 9th terms:

T₆ = a + (6 - 1)d = a + 5d

T₉ = a + (9 - 1)d = a + 8d

According to the problem, 6 times the 6th term of the A.P. is equal to 9 times the 9th term, so we can write the following equation:

6T₆ = 9T₉

Substituting the expressions for T₆ and T₉, we get:

6(a + 5d) = 9(a + 8d)

Expanding and solving for a, we get:

6a + 30d = 9a + 72d

Subtracting 6a from both sides:

24d = 3a + 72d

Subtracting 72d from both sides:

-48d = 3a

Dividing both sides by 3:

-16d = a

So, the first term of the A.P. is -16d.

To find the 15th term, we can use the formula for the nth term:

T₁₅ = a + (15 - 1)d = -16d + 14d = -2d

So, the 15th term of the A.P. is -2d.

After solving the fraction answer is 4 7/12 but the Susi's answer is 5 7/1. So the Susi's answer is wrong.

The given expression is 8 1/3- 3 3/4

We first solve that expression.

We convert mixed fraction into improper fraction.

After conversion we equal the denominator of of both fraction.

Then we subtract the fraction.

After solving we check Susi's answer is right or wrong.

To convert 8 1/3 into improper fraction we multiply 8 and 3 then we add 1 in the answer of multiplication of 8 and 3.

8 1/3 = 25/3

To convert 3 3/4 into improper fraction we multiply 3 and 4 then we add 3 in the answer of multiplication of 3 and 4.

3 3/4 = 15/4

Now the expression is:

= 25/3 - 15/4

Multiply and divide by 12 on both side

= 25/3 × 12/12 - 15/4 × 12/12

= (25 × 4)/12 - (15 × 3)/12

= 100/12 - 45/12

= (100 - 45)/12

= 55/12

= 4 7/12

The simplified answer of given expression is 4 7/12 but the Susi's answer is 5 7/1. So the Susi's answer is wrong.

The process of simplifying square roots involves finding an equivalent expression for the square root that has smaller or more manageable numbers inside the root sign.

This can be achieved by using prime factorization, the properties of square roots, and rationalizing the denominator. The final result should be in the simplest form possible, without any radicals in the denominator, or any perfect square factors in the numerator.

A square root is a number that, when multiplied by itself, gives the original number. For example, the square root of 9 is 3, because 3 x 3 = 9. The symbol for square root is √. For example, √9 = 3.

The square root of a number can be either positive or negative, but for most purposes, the positive square root is used.

AO = CO = AB/2 = 16/2 = 8 cm

BO = DO =12/2 = 6 cm

m∠AOB = 90°  Answer (i)

(ii) Since m∠AOB  = 90°, ΔAOB is a right triangle with AB as the hypotenuse and AO, BO as the legs of the right triangle

By the Pythagorean Theorem
AB² = AO² + BO²

AB² = 8² + 6²

AB² = 64 + 36

AB² = 100

AB = √100 = 10 cm   Answer (ii)

Answer:

Step-by-step explanation:

You have a rhombus ABCD with diagonals AC = 16 cm and BD = 12 cm. You want the magnitude of central angle AOB, and the length of one side, AB.

The diagonals of a rhombus bisect each other and cross at right angle. They divide the figure into four (4) congruent right triangles.

The central angle AOB has magnitude 90°.

Each of these right triangles will have leg lengths of 6 cm and 8 cm, which you recognize as having the ratio 3 : 4. These are the leg lengths of a 3:4:5 right triangle. In this rhombus, those right triangles have lengths 6 cm : 8 cm : 10 cm. The side AB of the rhombus is 10 cm.
