What is the area of the polygon?
Answer:
The answer is 34 m^2
Step-by-step explanation:
Well, we can divide the Polygon into pieces and solve the area for each piece.
There will be a rectangle and a trapezoid.
Area of Rectangle: Area = Length * Width
Area = Length * Width
Area = 6 m * 3 m = 18 m^2
Area of a Trapezoid: Area = [tex]\frac{h*(b1+b2)}{2}[/tex]
[tex]A=\frac{h*(b1+b2)}{2}\\A=\frac{4*(6+2)}{2}\\A=\frac{4*8}{2} \\A=\frac{32}{2} \\A=16 m^2[/tex]
Total Area = 16 m^2 + 18 m^2 = 34 m^2

Answer:
Question 12
Luisa's annual contributions:
Group Med = 25% of $12,98825% of $12,988
= 0.25 × $12,988
= $3,247
(a) Total annual contribution:
= Group Med + Dental + Vision
= $3,247 + $980 + $324
= $4,551
(b) Bi weekly deduction:
= $4,551 ÷ 365 × 14
= $174.56
OR
= $4,551 ÷ 52 × 2
= $175.04
**It depends how you calculate biweekly - if you divide the annual amount by 365 days then multiply by 14, OR if you divide the annual amount by 52 weeks then multiply by 2**
------------------------------------------------------------------------------------------------------
Question 13
Boris' annual contributions:
HMO = 10% of $8,190HOM - 10% of $8,190:
= 0.1 × $8,190
= $819
Dental - 50% of $662:
= 0.5 × $662
= $331
Vision - 50% of $288:
= 0.5 × $288
= $144
Total annual contribution:
= HMO + Dental + Vision
= $819 + $331 + $144
= $1,294
Weekly deduction:
= $1,294 ÷ 365 × 7
= $24.82
OR
= $1,294 ÷ 52
= $24.88
**It depends how you calculate weekly - if you divide the annual amount by 365 days then multiply by 7, OR if you divide the annual amount by 52 weeks**
------------------------------------------------------------------------------------------------------
Question 14
Annual contributions:
PPO = $12,640Dental = $866Vision = $444Total annual contribution:
= $12,640 + $866 + $444
= $13,950
Quarterly payments:
= $13,950 ÷ 4
= $3,487.50

The dance committee hired DJ Emanuel for the fall
dance. DJ Emanuel charges $I25 per hour plus $55 for
an assistant. The committee wants to keep the total
cost under $600. What is the maximum number of
hours that DJ Emanuel can play at the dance?
I need the inequality, inequality answer, final answer
Answer:
Inequality: 125x + 55 < 600
Solution of inequality: x < 4.36
Final answer: 4 hours
Step-by-step explanation:
Let the number of hours be x.
1 hour costs $125.
2 hours cost $125 × 2
3 hours cost $125 × 3
x hours cost $125 × x or simple 125x.
The assistant costs $55.
The total cost is 125x + 55.
The cost must be under $600, so
125x + 55 < 600
Subtract 55 from both sides.
125x < 545
Divide both sides by 125.
x < 4.36

Write the standard form equation of each circle.
Center: (-11, -8) Radius: 4
Center: (-6, -15) Radius: square root of 5
Answer:
(x+11)^2 + (y+8)^2 = 4^2/16
(x+6)^2 + (y+15)^2 = 5
Step-by-step explanation:
the standard equation of a circle is
(x-h)^2 + (y-k)^2 = r^2 where (h,k) is the center and r is the radius
in the first equation -11 is h and -8 is k
so (x+11)^2 because when you subtract a negative the double negative creates a positive and that’s the same for (y+8)^2
so (x+11)^2 + (y+8)^2 = 4^2 or 16
in the second equations -6 is h and -15 is k
and the double negative is also effective in this equation so (x+6)^2 and (y+15)^2 therefore, (x+6)^2 + (y+15)^2 = 5 (the square root of 5 squared is just 5)
hope this helps :)

determine whether each of the following sequences are arithmetic, geometric or neither. If arithmetic, state the common difference. If geometric, state the common ratio. -29, -34, -39, -44, -49, ...
Is this: common difference =5?
arithmetic?
[tex]\qquad\qquad\huge\underline{{\sf Answer}}[/tex]
[tex] \textbf{Let's see if the sequence is Arithmetic :} [/tex]
[tex] \textsf{If the difference between successive terms is } [/tex] [tex] \textsf{equal then, the terms are in AP} [/tex]
[tex] \textsf{-34 - (-29) = -5 } [/tex][tex] \textsf{-39 - (-34) = -5 } [/tex][tex] \textsf{Since the common difference is same, } [/tex] [tex] \textsf{we can infer that it's an Arithmetic progression} [/tex] [tex] \textsf{with common difference of -5} [/tex]
Sequence: -29, -34, -39, -44, -49, ...
First we need to identify the terms:
1st term = -292nd term = -343rd term = -394th term = -445th term = -49If the sequence is arithmetic, [tex]\boxed{\sf \bold{second \ term = \dfrac{first \ term+third \ term}{2} }}[/tex]
If the sequence is geometric, [tex]\boxed{\sf \bold{second \ term = \sqrt{first \ term \ x \ third \ term} }}[/tex]
=======================================
Check for arithmetic
[tex]\rightarrow \sf -34 = \sf \dfrac{-29 +(-39)}{2}[/tex]
[tex]\rightarrow \sf -34 = \sf \dfrac{-68}{2}[/tex]
[tex]\rightarrow \sf -34 = -34[/tex] [Hence it's arithmetic series]
To find common difference. we have to think of how to go to next term.
first term: -29
to go the second term, subtract by -5
-29 -5 = -34, second term
-34 - 5 = -39, third term
Hence, common difference: -5
Solutions:
Arithmetic Sequence
Common Difference: -5

What is the sum of the complex numbers 2 + 4i,and 3 − 7i, where i=-1
Answer:
5 - 3i.
Step-by-step explanation:
2 + 4i + 3 - 7i Bring like terms together:
= 2 + 3 + 4i - 71
= 5 - 3i.
Answer:
5 - 3i
Step-by-step explanation:
Real numbers are a subset of the complex numbers. Therefore it would only make sense that the complex numbers follow the same rule of additivity and multiplication as real numbers do:
[tex](2+4i)+(3-7i)=2+3+4i-7i=5-3i[/tex]

Sum of a finite geometric series:
Sn=a1-a1r / 1-r
Answer:
19,531,248
Step-by-step explanation:
General form of a geometric sequence: [tex]a_n=ar^{n-1}[/tex]
(where [tex]a[/tex] is the first term and [tex]r[/tex] is the common difference)
Given geometric series: 8 + 40 + 200 + ... + 15625000
[tex]\implies a_1=8[/tex]
[tex]\implies a_2=40[/tex]
[tex]\implies a_3=200[/tex]
To find the common ratio [tex]r[/tex], divide consecutive terms:
[tex]\implies r=\dfrac{a_2}{a_1}=\dfrac{40}{8}=5[/tex]
Therefore:
[tex]\implies a_n=8(5)^{n-1}[/tex]
To find n when [tex]a_n=15625000[/tex] :
[tex]\implies 8(5)^{n-1}=15625000[/tex]
[tex]\implies (5)^{n-1}=1953125[/tex]
[tex]\implies \ln (5)^{n-1}=\ln1953125[/tex]
[tex]\implies (n-1)\ln 5=\ln1953125[/tex]
[tex]\implies n=\dfrac{\ln1953125}{\ln5}+1[/tex]
[tex]\implies n=10[/tex]
Sum of the first n terms of a geometric series:
[tex]S_n=\dfrac{a(1-r^n)}{1-r}[/tex]
Therefore, sum of the first 10 terms:
[tex]\implies S_{10}=\dfrac{8(1-5^{10})}{1-5}[/tex]
[tex]\implies S_{10}=19,531,248[/tex]

The second function has a slope of -3 and a y-intercept of 8
How to interpret the function?The function is given as:
h(x) = -3x + 8
The above function is a linear function.
A linear function is represented as:
y = mx + b
Where:
m represents the slope and b represents the y-intercept
By comparison, we have:
