Answer:

B

Step-by-step explanation:

The vertex form of an absolute value function is f(x)=a|x-h|+k where (h,k) is the vertex.

a is positive means the absolute value function will face up.

a is negative means the absolute value function will face down.

So looking at the picture we see the vertex is (2,3) and all of the choices have a is 1.

So plugging in 2 for h and 3 for k and 1 for a into f(x)=a|x-h|+k

f(x)=|x-2|+3.

ANSWER

The diagonal of the square is 6 units.

EXPLANATION

A diagonal of a square divides the square into two congruent right isosceles triangles.

Let the sides of the square be 's' units. Then, the Pythagoras Theorem says that, the sum of the squares of the shorter legs will be equal to the square of the hypotenuse.

Let the diagonal which is the hypotenuse be 'd' units.

Then,

[tex] {d}^{2} = {s}^{2} + {s}^{2} [/tex]

[tex] \implies \: {d}^{2} = 2{s}^{2}[/tex]

From the question, the side length of the square is

[tex]s = 3 \sqrt{2} \: units[/tex]

We plug in this value to obtain:

[tex]\implies \: {d}^{2} = 2{(3 \sqrt{2} )}^{2}[/tex]

Or

[tex]\implies \: {d}^{2} = 2 \times { {3}^{2} (\sqrt{2} )}^{2}[/tex]

[tex]\implies \: {d}^{2} = 9 \times 2 \times 2 = 36[/tex]

We take the positive square root of both sides to get:

[tex]d = \sqrt{36} [/tex]

[tex]d = 6 \: units[/tex]

Answer: The crop yield increased by 9 pounds per acre from year 1 to year 10.

Step-by-step explanation:

To solve this we are using the average rate of change formula: Av=\frac{f(x_2)-f(x_1)}{x_2-x_1}, where:

x_2 is the second point in the function

x_1 is the first point in the function

f(x_2) is the function evaluated at the second point

f(x_1) is the function evaluated at the first point

We know that the first point is 1 year and the second point is 10 years, so x_1=1 and x_2=10. Replacing values:

Av=\frac{-(10)^2+20(10)+50-[-(1)^2+20(1)+50]}{10-1}

Av=\frac{-100+200+50-[-1+20+50]}{9}

Av=\frac{150-[69]}{9}

Av=\frac{150-69}{9}

Av=\frac{81}{9}

Av=9

Since f(x) represents the number of pounds per acre and x the number of years, we can conclude that the crop yield increased by 9 pounds per acre from year 1 to year 10.

Final answer:

To identify which function the graph represents, analyze the shape and pattern of the graph. The correct function could either be a polynomial such as y = x^4, which has a sharply rising curve, or a logarithmic function with a declining curve due to having a base between 0 and 1, like y = log(1/4)x, but not y = log1x as this is not mathematically valid.

Explanation:

The question requires the identification of a function based on its graph. Since the properties of functions are known, such as the logarithmic function increasing as x increases, and the behavior of exponential functions and their inverses, we can analyze the options given. The function y = log1x is not valid as the base of a logarithm cannot be 1. The function y = x4 is a polynomial function with a graph that rises sharply for positive and negative values of x. Lastly, y = log(1/4)x represents a logarithmic function with base 1/4, which is a declining curve because the base is between 0 and 1.

To choose the correct function that a graph represents, one should look for key characteristics such as the shape of the graph, increase or decrease pattern, as well as specific points like asymptotes or intercepts. If the graph is increasing as x increases and resembles a typical logarithmic curve, the correct choice is a logarithmic function. If the given graph is a sharp rising curve for all x-values and looks like a polynomial, then y = x4 would be correct. The given functions need to be analyzed based on their mathematical properties to select the one that best describes the graph in question.

Answer:

* cos 211.7 not equal the other values

Step-by-step explanation:

* Lets revise the angles in the four quadrant

- If the angle in the first quadrant is Ф, then the equivalent angles to

 it in the other three quadrant are

# 180° - Ф ⇒ 2nd quadrant (sin only +ve)

# 180° + Ф ⇒ 3rd quadrant (tan only +ve)

# 360° - Ф ⇒ 4th quadrant (cos only +ve)

# -Ф ⇒ 4th quadrant (cos only +ve)

# -180 + Ф ⇒ 3rd quadrant (tan only +ve)

# -180 - Ф ⇒ 2nd quadrant (sin only +ve)

# -360 + Ф ⇒ 1st quadrant (all are +ve)

* Lets solve the problem

∵ Ф = 31.7°

∵ cos 31.7 = +ve value

∵ 180° + Ф° = 180° + 31.7° = 211.7°

∵ cos (180° + Ф°) = - cos Ф° ⇒ cos (180° + Ф°) in the 3rd quadrant is

  same value as cos Ф but with -ve sign

∴ cos 211.7° = - cos 31.7°

∴ cos 31.7° ≠ cos 211.7°

∵ 360° - Ф° = 360° - 31.7° = 328.3°

∵ cos (360° - Ф°) = cos Ф° ⇒ cos (360° - Ф°) in the 4th quadrant has the

  same value and sign with cos Ф°

∴ cos 328.3° = cos 31.7°

∴ cos 31.7° = cos 328.3°

∵ -391.7° + 360° = -31.7° ⇒ more then clockwise turn by 31.7°

∵ cos (-Ф°) = cos Ф° ⇒ cos (-Ф°) in the 4th quadrant has the same value

  and sign with cos Ф°

∴ cos (-31.7°) = cos 31.7°

∴ cos 31.7° = cos (-390.7°)

* cos 211.7 not equal the other values

Answer:

Mean Absolute Deviation = 3.

Step-by-step explanation:

The mean = (2 + 9 + 1 + 7 + 8 + 9) / 6

= 36/6

= 6.

Subtract  6 from each  number:

2 - 6 = -4 Absolute value = 4

9 - 6 = 3

1 - 6 = -5 Absolute value = 5

7 - 6 = 1

8 - 6 = 2

9 - 6 = 3

Total = 4 + 3 + 5 + 1 + 2 + 3 = 18

Mean Absolute Deviation = 18 / 6 = 3.

Answer:

B: 3

Step-by-step explanation:

First you will take the numbers and add them. The equation would be 2 + 9 + 1 + 7 + 8 + 9. That equals 36.

Then, you may divide that by 6 (how many numbers there were) and that is your mean (also 6).

Next, you find the how far each number is from the mean using absolutes. Those values are 4, 3, 5, 1, 2, and 3.

Finally, add those together to get 18, then divide by how many numbers there were (6) that to get the mean absolute deviation (3).

Answer:

C. $6 per hour.

Step-by-step explanation:

Pick a convenient point on the graph. The rate of change  is the

y coordinate /  x coordinate.

So we pick the point near the top right corner where y = 30 and x = 5 which gives us the answer 30/5 = 6.

The rate of change shown in the graph is option B that is $3 per hour.

The rate of change in a line is the difference between vertical values divided by horizontal values. It is also known as slope. It can be calculated as under:

Rate of change= y2-y1/x2-x1

To calculate the rate of change we need to first select two points which are in the given graph are (0,0) and (1,3)

Rate of change is equal to (3-0)/(1-0)

=3/1

means $ 3 is paid for 1 hour.

Hence the rate of change in the given graph is $3 per hour.

Final answer:

The Pythagorean theorem relates the lengths of the legs and hypotenuse of a right triangle. By substituting the given values into the equation, we can solve for x using the theorem. The rounded value of x is 3.6 (B).

Explanation:

The Pythagorean theorem relates the length of the legs of a right triangle, labeled a and b, with the hypotenuse, labeled c. The relationship is given by: a² + b² = c². This can be rewritten, solving for c: c = √(a² + b²).

In this case, we want to find the value of x using the Pythagorean theorem. Let's say that the lengths of the legs are 3 and x. Substituting these values into the theorem, we have:

3² + x² = c²

Now, we can solve for x by rearranging the equation:

x² = c² - 3²

x = √(c² - 3²)

Rounding to the nearest tenth, we can find the value of x to be approximately 3.6 (B).

Final answer:

The Pythagorean theorem allows us to calculate the length of the hypotenuse of a right triangle by squaring the lengths of the other two sides, adding them together, and then taking the square root. To round to the nearest tenth, we calculate and then round the final result accordingly.

Explanation:

To use the Pythagorean theorem to find x and round to the nearest tenth, we need to establish the components of the equation. The theorem states that in a right triangle, the square of the hypotenuse (c) is equal to the sum of the squares of the other two sides (a and b). The formula is written as a² + b² = c².

However, the problem provided does not include the initial lengths to insert into the equation; hence, we cannot compute the value directly. Nonetheless, I can illustrate with a hypothetical example:

If we have a right triangle with legs of lengths 9 (a) and 6 (b), then the hypotenuse (c) can be found as follows:

c = √(9² + 6²)
c = √(81 + 36)
c = √117
c = 10.82, round off to the nearest tenth would be c = 10.8

In this example, we squared the lengths of the legs, added them together, and took the square root of the result to find the hypotenuse to the nearest tenth. The same steps apply to any right-angled triangle where you are given the lengths of the legs and need to find the hypotenuse using the Pythagorean theorem.

C. 60,000

Step-by-step explanation:

Given

Three times as many bought tickets

24,000 * 3 = 72,000

one-sixth of them cancelled their tickets

72,000 * 1/6 = 12,000

Subtract

72,000 - 12,000 = 60,000

Answer

60,000 people are attending this week

This week, 60,000 fans are attending the football match.

To find the number of fans attending the football match this week, we need to start with the number of fans who bought tickets. This week, three times as many fans bought tickets as last week, so there were 3 * 24,000 = 72,000 fans who bought tickets. However, one-sixth of them cancelled their tickets, which means 1/6 * 72,000 = 12,000 fans cancelled. Therefore, the number of fans attending the match this week is 72,000 - 12,000 = 60,000.

Step-by-step explanation:

∠XYZ is an inscribed angle, where its vertex is located on the circle and two intersecting chords form the vertex.

An inscribed angle is equal to HALF of the intercepted arc, which is the arc that is between the two points where the chords hit.

In this picture, the intercepted arc is the red part of the outside of the circle.

Since you are given the measurement of the intercepted arc, you can find the measure of the inscribed angle by finding half of 148°.

Therefore, the inscribed angle is 148° divided by 2, giving us 74°.

The measure of the inscribed angle, ∠XYZ, is D. 74°.
