Answer:
Perimeter = 5.67
Step-by-step explanation:
AB = sqrt{-1 - (0)} + (-2 - (-4)}
Multiply -1 by 0
sqrt(-1 + 0 - 2 - (-4)
-1 by -4
sqrt(-1 + 0 - 2 + 4
Add -1 and 0
sqrt(-1 - 2 + 4)
Subtract 2 from -1
sqrt(-3 + 4)
Add
Sqrt(1) > 1
BC = sqrt{5 - (-1)} + {-3 - (-2)}
Multiply -1 by -1
sqrt(5 + 1 - 3 - (-2)
-1 by -2
sqrt(5 + 1 - 3 + 2
Add 5 and 1
sqrt(6 - 3 + 2)
Add 3 and 2
Sqrt(5) > 2.23
AC = sqrt{5 - 0} + {-3 - (-4)}
Multiply -1 by 0
sqrt(5 + 0 - 3 - (-4)
-1 by -4
sqrt(5 + 0 - 3 + 4)
Add 5 and 0
sqrt(5 - 3 + 4)
Subtract 3 from 5
sqrt(2 + 4)
Add
Sqrt(6) > 2.44
Perimeter = AB + BC + AC
Sqrt(1) + Sqrt(5) + Sqrt(6) = 1 + 2.23 + 2.44 = 5.67

Step-by-step explanation:
Jan is making a logo for her company. She begins with a 6-cm-by-12-cm rectangle. Two points along the bottom side divide that side into three equal pieces. A point on the top side divides that side into two equal pieces. The logo itself is the total shaded area, as shown. What is the area of the shaded logo, in square cm?
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
How is the area of the logo calculatedThe logo is a trapezoid with the following dimensions
Height = 12 cmParallel sides: 6 cm and 2 cmThe 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

Step-by-step explanation:
If you want to get $15 profit, You will need to paint 9 faces. You spent $12 on painting supplies so this is the explanation.
$3 x 9 = $27
$-12 + $27 = $15
That way, you earn $15.
NO LINKS!!! Use the following graph of f(x) to answer the following below.
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)
Winning The Jackpot In A Particular Lottery Requires That You Select The Correct Four Numbers Between 1 And 54 and, in a separate drawing, you must also select the correct single number between 1 and 37. find the probability of winning the jackpot
It can be deduced that the probability that an individual wins the jackpot will be 0.0000001.
How to calculate the probabilityFrom the information, the required four numbers will be:
= 54! / 4!(54 - 4)!
= 54! / 4!50!
= 316251
The required single number will be:
= 37! /1! (37 - 1)!
= 37
Therefore, the probability of winning the jackpot will be:
= 1 / (316251 × 37)
= 1/11701287
= 0.0000001

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

wich is greter 6/10 or 9/8
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.

no
yes; 1/7
yes;7
yes;-7
Answer:
(d) yes; -7
Step-by-step explanation:
The differences between terms are ...
12 -19 = -7
5 -12 = -7

These are all the same, so this difference is "common". A sequence in which terms have a common difference is an arithmetic sequence.
This sequence is arithmetic, with a common difference of -7.
What is the measure of angle PBQ
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
