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:

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)

__

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

  critical points: (2, 4) and (8, -2)

__

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)

__

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

  domain: [-6, 11]

  range: [-3, 4]

__

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

__

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.

__

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)

The area of a shape is the amount of space the shape occupies

The area of the shaded region in square cm is 48 square cm

The logo is a trapezoid with the following dimensions

The area of a trapezoid is:

Area = 0.5 * Height * (Sum of parallel sides)

Substitute known values

Area = 0.5 * 12 cm * (6cm + 2cm)

Evaluate

Area = 48 square cm

Hence, the area of the logo i.e. shaded region is 48 square cm

The table which  represents a quadratic relationship is in option [tex]D[/tex].

A quadratic relationship is a mathematical relation between two variables that follows the form of a quadratic equation.

Quadratic sequence [tex]=an^2 +bn+c[/tex]

So, According to the definition mentioned above if table follows the  form of a quadratic equation then it is in quadratic relationship.

So,

To find out quadratic relationship,

We will find first difference in every table and then second difference (Second difference is the difference between the first difference).

We have,

Table A;

[tex]\left \begin{array}{ccccc}x& \ &f(x)&First\ Difference & Second\ Difference \\-2& &4&2-4=-2\\-1& &2&1-2=-1&-1+2=1\\0& \ &1&0.5-1=-0.5&-0.5+1=0.5\\1& &0.5&0.25-0.5=-0.25&-0.25+0.5=0.25\\2& &0.25&0.125-0.25=-0.125\\3& &0.125\end{array}\right[/tex]

So, In the above table we can see that second difference  is not equal that means it is not in quadratic relationship.

Now,

Let Table D;

[tex]\left \begin{array}{ccccc}x& \ &f(x)&First\ Difference & Second\ Difference \\-2& &-23.4&\\-1& &-23.2&-23.2+23.4=-0.2&0.2-0.2=0\\0& \ &-23&-23+23.2=-0.2&0.2-0.2=0\\1& &-22.8&-22.8+23=-0.2&0.2-0.2=0\\2& &-22.6&-22.6+22.8=-0.2\\3& &-22.4&-22.4+22.6=-0.2\end{array}\right[/tex]

So, here in this table, we can see that second difference  is equal that means it is in quadratic relationship.

Hence, we can say that the table which  represents a quadratic relationship is in option [tex]D[/tex].

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.

Answer:

m∠PBQ=51

Step-by-step explanation:

By vertical angles theorem, ∠PBQ ≅ ∠LBM, so m∠PBQ=m∠LBM.

And since ∠LBM & ∠LBQ are supplementary, we'll write,

m∠LBM+LBQ=180°

3x+(4x+61)=180°

Let's solve for x:

7x=119

7x/7=119/7

x=17

So...

m∠LBM=3(17)

m∠LBM=51

This means that m∠PBQ=51
