Write a recursive sequence that represents the sequence defined by the
following explicit formula:
An = 1 - 5(n − 1)
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:
aₙ = aₙ₋₁ - 59=y + 6 what does it equal

Solve the equation.
x+2y=0
Answer: y=-(x/2)
Graph it to figure out.
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
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

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°

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
Answer:
C
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
