Answer: f(8) = 6.25(1.1)^7 ; f(8) = 12.179
Step-by-step explanation: (I got it right on the test)
(1, 6.25), (2, 6.875), (3, 7.5625), (4, 8.31875)
r= 1.1
f(1) = 6.25 / starting number
1. Since it is multiplying each number by 1.1 it is using the Geometric Explicit Formula:
f(n)= f(1) x r ^n-1
f(8) = 6.25 x 1.1 ^(8-1)
f(8) = 6.25 x 1.1 ^7
f(8) = 6.25 x 1.9487171
f(8) = 12.179
Answer:
x = 5
Step-by-step explanation:
=(-5-√-75)/2=(-5-5i√ 3 )/2= -2.5000-4.3301i
x =(-5+√-75)/2=(-5+5i√ 3 )/2= -2.5000+4.3301i
x = 5
