NO LINKS!!! Use the following graph of f(x) to answer the following below.

Answers

Answer:

  a) inc: (-6, 2) ∪ (8, 11); dec: (2, 8)

  b) (2, 4) and (8, -2)

  c) min: (-8, -3); max: (2, 4)

  d) D: [-6, 11]; R: [-3, 4]

  e) -2

  f) {0, 4}

  g) up: (6, 10); down: (0, 6) ∪ (10, 11)

Step-by-step explanation:

a)

The graph is increasing where the slope is positive. The graph is decreasing where the slope is negative. Points where the slope is zero are not part of the interval. End points of the domain are generally not included, either.

  increasing: (-6, 2) ∪ (8, 11)

  decreasing: (2, 8)

__

b)

Critical points are points where the slope is zero (tangents are horizontal) or undefined (tangents are vertical).

  critical points: (2, 4) and (8, -2)

__

c)

Minima and maxima are found either at turning points or the ends of the domain. Here, we have ...

  absolute minimum: (-8, -3)

  local minimum: (8, -2)

  local maximum: (11, 1)

  absolute maximum: (2, 4)

__

d)

The domain is the horizontal extent of the graph. The range is the vertical extent.

  domain: [-6, 11]

  range: [-3, 4]

__

e)

To find the function value for a given value of x, locate that value of x on the graph and see where the function crosses that vertical grid line. Here, the point is marked (8, -2).

  f(8) = -2

__

f)

Points where f(x) = 3 will have y-coordinates of 3. They will be at the intersection of the horizontal line y=3 and the graph. Here, they are marked for you:

  f(0) = 3

  f(4) = 3

The values of x where f(x) = 3 are 0 and 4.

__

g)

Concavity switches from up to down, or vice versa, at points of inflection. Here, the points of inflection are hard to determine. We will assume they are the points marked (6, 0) and (10, 0).

Where the graph has a ∩ shape (slope is decreasing), the concavity is down. Where the graph has a ∪ shape (slope is increasing), the concavity is up. The slope on the interval (-6, 0) is constant at +1, so is neither increasing nor decreasing. There is no concavity on that interval.

 concave down: (0, 6) ∪ (10, 11)

  concave up: (6, 10)

y = 3 - x

y = 3 - (-3)

lou eats 6/8 of a pizza. what fraction of the pizza, in simplest form, is left over

Answers

2/8 is equivalent to 1/4

Answer:

[tex]\frac{1}{4}[/tex]

Step-by-step explanation:

[tex]\frac{6}{8}[/tex]

A full pizza would be a whole; 1 or [tex]\frac{8}{8}[/tex]. So you must subtract the amount Lou eats, to the original amount.

[tex]\frac{8}{8} - \frac{6}{8} = \frac{2}{8}[/tex]

[tex]\frac{2}{8} = \frac{1}{4}[/tex]

Your final answer will be [tex]\frac{1}{4}[/tex].

wich is greter 6/10 or 9/8

Answers

Answer:

9/8

Step-by-step explanation:

There are a few ways to look at this.

Starting with the easier way, we see that 9/8 is a fraction above one (this is when the numerator is greater than the denominator), while 6/10 is not, therefore 9/8 is the greater fraction.

Next, we can find the common denominator of the fractions. The least common multiple of 10 and 8 is 40. Now, we can multiply 6/10 by 4 (because 10 x 4 = 40) and 9/8 by 5 (because 8 x 5 = 40)

As a result, we get 24/40 and 45/40, and we can see that 45 is greater than 24.


3.If ABCD is a parallelogram with AB = 2x + 1, AD = x + 13, and DC = 3x -11. Determine if ABCD is
rhombus. Show algebraic work to justify your answer.

Answers

Answer:

  ABCD is a rhombus

Step-by-step explanation:

Sides AB and DC are opposite and equal in parallelogram ABCD. This means ...

  AB = CD

  2x +1 = 3x -11

  12 = x . . . . . . . . add 11-2x to both sides

Sides AB and CD have length ...

  2x +1 = 2(12) +1 = 24 +1 = 25

Then the length of side AD is ...

  AD = x +13 = 12 +13 = 25

Adjacent sides AB and AD of the parallelogram have the same length, The figure is a rhombus.

A boat is heading towards a lighthouse, whose beacon-light is 102 feet above the water. From point AA, the boat’s crew measures the angle of elevation to the beacon, 7 , before they draw closer. They measure the angle of elevation a second time from point b at some later time to be 12. Find the distance from point A to point B. Round your answer to the nearest foot if necessary.

Answers

Answer:

351 ft (nearest foot)

Step-by-step explanation:

Model the problem as a right triangle, where the horizontal leg is the water (where the boat is at the vertex with the hypotenuse), and the vertical leg is the lighthouse.  The angle of elevation is between the boat and the top of the lighthouse. (see attached diagram)

Horizontal distance from point A to the lighthouse

Using the trig ratio tan(x) = O/A where x is the angle, O is the side opposite to the angle and A is the side adjacent to the angle:

Given:

x = 7O = 102 A = ?

⇒ tan(7) = 102/A

⇒ A = 102/tan(7)

⇒ A = 830.7233357... ft

Horizontal distance from point B to the lighthouse

Given:

x = 12O = 102 B = ?

⇒ tan(12) = 102/B

⇒ B = 102/tan(12)

⇒ B = 479.8722712... ft

Therefore, distance from A to B:

⇒ distance = A - B

⇒ distance = 830.7233357... - 479.8722712...

⇒ distance = 350.8510645...

⇒ distance = 351 ft (nearest foot)

Answer:

a is 64 degrees

b is 138.6667

Step-by-step explanation:

a is simple because you know a straight line has 180 degrees and since one side is 116 you simply subtract 180-116=64.

b is more complicated. Since a hexagon has a total internal angle of 720. 3 angle measures are given.

720-116- (180-82)-90=416

Since the last three angles are the same, you can divide by 3.

416/3=138.6667

Hopefully I didnt make any calculation errors because there is a lot of calculating for b.
