This is a geometric sequence with a common ratio of 2
an = a1 * r^(n - 1)
n = term to find = 21
a1 = first term = 0.05
r = common ratio = 2
now we sub
a21 = 0.05 * 2^(21 - 1)
a21 = 0.05 * 2^20
a21 = 0.05 * 1048576
a21 = 52428.80 <==== after working 21 days

Given that XZ = 8x - 2 and YZ = 2x + 1 and that Y is the midpoint of line XZ.
2YZ = XZ
2(2x + 1) = 8x - 2
4x + 2 = 8x - 2
8x - 4x = 2 + 2
4x = 4
x = 1.
Answer:
Step-by-step explanation:
1. 4x + 5 = -7
4x = -12
x = -3
2. 9f - 11 = 4 + 14f
-5f - 11 = 4
-5f = 15
f = -3
