What are the values of x and y if you answer is not a whole number write it as a decimal and round if neccasasry

Answers

a) 3x + 5y = 26

b) 2x + 2y = 12

First, we need to find a way to equate either the x terms or the y terms in each equation. a) 6x + 10y = 52

b) 6x + 6y = 36

Then take equation b) from the equation a) to eliminate the x component.

a) 6x + 10y = 52

- b) 6x + 6y = 36

0x + 4y = 16

y = 4 ?

Then substitute the value of y into either equation to find the value of x.

b) 2x + 2y = 12

2x + (2x4) =12

2x + 8 = 12

2x = 4

x = 2

A sector of a circle has an arc length of π cm and a central angle of π6 radians. What is the area of the sector?

A. 5π cm²
B. 2π cm²
C. 3π cm²
D. π cm²

Answers

Answer:

Step-by-step explanation:

The Area of sector is π cm². so option D is correct.

How to find the area of a sector of a circle?

The sector of a circle is like a slice of a circular pizza.

[tex]A = \dfrac{x \times \pi r^2}{360} \: \rm unit^2 area[/tex]

Mathematically π radians = 180 degrees

thus, π /6 radians = 180/6 = 30 degrees

The formula for the length of an arc is;

Ф/360 x 2πr

where Ф, is 30 degrees

And the arc length is pi

so we have

30/360 x 2πr = π

30/360 x 2r = 1

60r = 360

r = 360/60

r = 6 cm

Now the area of a sector is;

Ф/360 x πr^2

30/360 x π36

= π cm^2

Write a recursive sequence that represents the sequence defined by the
following explicit formula:
An = 1 - 5(n − 1)

Answers

Answer:

[tex]a_1=1\\a_n=a_{n-1}-5[/tex]

Step-by-step explanation:

a₁ = 1 - 5(1 - 1) = 1 - 5·0 = 1

a₂ = 1 - 5(2 - 1) = 1 - 5·1 = 1 - 5 = a₁ - 5

a₃ = 1 - 5(3 - 1) = 1 - 5·2 = 1 - 5 - 5 = a₂ - 5

a₄ = 1 - 5(4 - 1) = 1 - 5·3 = 1 - 5 - 5 - 5 = a₃ - 5

and so on, therefore:

Answer:

∠ B = 54°

Step-by-step explanation:

Supplementary angles sum to 180°, so

7x + 7 + 4x - 14 = 180

11x - 7 = 180 ( add 7 to both sides )

11x = 187 ( divide both sides by 11 )

x = 17

Then

∠ B = 4x - 14 = 4(17) - 14 = 68 - 14 = 54°

Gomez isn’t sure what to do. Should he put his $3000 into an account paying 6% for 10 years compounded annually or should he put into an account paying 10% for five years?

Answers

Answer:

If these are the only two options, the most profitable is the first option (6% and 10 years).

Step-by-step explanation:

Giving the following information:

Initial investment (PV)= $3,000

Number of periods (n)= 10 years or 5 years

Interest rate (i)= 6% or 10%

To calculate the future value (FV), we need to use the following formula:

FV= PV*(1 + i)^n

6% interest rate:

FV= 3,000*(1.06^10)

FV= $5,372.54

10% interest rate:

FV= 3,000*(1.1^5)

FV= $4,831.53

If these are the only two options, the most profitable is the first option (6% and 10 years).
