Answer:

Question 12

Luisa's annual contributions:

25% 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:

HOM - 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:

Total annual contribution:

= $12,640 + $866 + $444

= $13,950

Quarterly payments:

= $13,950 ÷ 4

= $3,487.50

[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{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:

If 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

Answer:

27, 5, 2

Step-by-step explanation:

This is really simple lol.

a. Simple Math terms

43 subtracted by 16 equals 27.

Let's do 46-16 which equals 30.

Subtract 3 from 30.

43-16=27.

a. Mathematical

43-16 = . . .

13 - 6 = 7

Subtract the 1 from 4.

3 - 1 = 2

43-16=27.

b. Simple Math terms

67-14=53

7-4 = 3

6-1=5

c. Simple Math terms

6-4=2

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 :)

Answer:

y = 5

Step-by-step explanation:

The equation for a line is y = mx + b, with m representing slope and b representing y-intercept.

This yields an equation y = 0x + 5, or just y = 5 when simplifying.

Answer:

Standard Deviation, σ: 8.9580641647762

Step-by-step explanation:

i used a calc for the first one

The second function is a linear function

The second function has a slope of -3 and a y-intercept of 8

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:

m = -3 and b = 8

Hence, the second function has a slope of -3 and a y-intercept of 8

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:

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]

Answer: 28

Step-by-step explanation:

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
