The value of c from the given expression is -
<h3>Function and values</h3>
Given the following function
c(n)= −c(n−1)+1
Given the following parameters
c(1)=3
Substitute
3 = −c(3−1)+1
3 = -2c + 1
-2c = 3-1
-2c = 2
c = -1
Hence the value of c from the given expression is -1

The modes are 8 and 9 in the data.
Answer:
6. r = 21 cm
7. A = 155.5 m²
Step-by-step explanation:
7: Formula for arc length is;
S = (θ/360) × 2πr
We are given;
S = 51 cm
θ = 139°
Thus;
51 = (139/360) × 2π × r
Making r the subject;
r = (51 × 360)/(2π × 139)
r ≈ 21 cm
8) Area of sector is gotten from the formula;
A = (θ/360) × πr²
A = (220/360) × (π × 9²)
A = 155.5 m²
6x + 5 = 4x + 5
2x + 5 = 5
2x = 0, x = 0
Y = 6(0) + 5, y = 5
Solution: x = 0, y = 5
