Answer:
f(n) = f(n-1) + 8ⁿ⁻¹
Step-by-step explanation:
The series is 5, 13, 29, 61, 125
13 - 5 = 8
29 - 13 = 16
61 - 29 = 32
125 - 61 = 64
Here, f(1) = 5
∴ f(2) = f(1) + 8¹ = 5 + 8 = 13
f(3) = f(2) + 8² = 13 + 16 = 29
f(4) = f(3) + 8³ = 29 + 32 = 61
And so on
∴ f(n) = f(n-1) + 8ⁿ⁻¹
Answer:
d = 6√3 inches ≈ 10.40 inches
Step-by-step explanation:
d² = a² + c²
= 36 + 72
= 108
d = √108
= √3×36
= √3×6²
= 6√3 inches
= 6×1.73 inches
= 10.38 inches
≈ 10.40 inches
Answer:
k = -2
Step-by-step explanation:
Given equation
1-kx = -3y
point on this line = (4,-3)
If point lies on the given line, then if we plug in the value (4,-3), then it will satisfy the equation
1-kx = -3y
using x = 4 and y = -3
1-k*4 = -3*-3
1 - 4k = 9
=> -4k = 9 -1 = 8
=> k = 8/-4 = -2
Thus, value of k is -2
