Find the first four terms of a sequence using the recursive definition. Please help
Ymorist [56]

Answer:

2, 5, 9, 19

Step-by-step explanation:

Using the recursive formula f(n) = 2f(n - 2) + f(n - 1)

with f(1) = 2 and f(2) = 5

f(3) = 2f(3 - 2) + f(3 - 1)

     = 2f(1) + f(2) = (2 × 2) + 5 = 4 + 5 = 9

f(4) = 2f(4 - 2) + f(4 - 1)

      = 2f(2) + f(3) = (2 × 5) + 9 = 10 + 9 = 19

The length of a rectangle is 4 cm more than the width. The are is 96 cm squared. Find the dimensions of the rectangle.
lozanna [386]

width = w

length = w+4

Area = l*w

substitute

96 = (w+4) *w

distribute

96 = w^2 +4w

subtract 96 from both sides

0 = w^2 +4w -96

factor

0=(w+12) (w-8)

w+12=0  w-8=0

w=-12  w=8

cannot have negative width

w=8

l=12

Answer:  width =8 cm

length = 12cm
