Answer:
Step-by-step explanation:
Let x, y , and z be the numbers.
Then the geometric sequence is
Recall that term of a geometric sequence are generally in the form:
This implies that:
a=32 and
Substitute a=32 and solve for r.
Take the fourth root to get:
Therefore
Answer:
x ≈ - 9.41, x ≈ - 6.59
Step-by-step explanation:
Given
x² + 16x + 62 = 0 ( subtract 62 from both sides )
x² + 16x = - 62
To complete the square
add ( half the coefficient of the x- term )² to both sides
x² + 2(8)x + 64 = - 62 + 64
(x + 8)² = 2 ( take the square root of both sides )
x + 8 = ± ( subtract 8 from both sides )
x = - 8 ±
Hence
x = - 8 - ≈ - 9.41
x = - 8 + ≈ - 6.59
