Answer:
43,000
Step-by-step explanation:
2 * 6^(n-1)
a(sub4) = 2 * 6^(4-1)
a(sub4) = 2 * 6^3
a(sub4) = 2 * 216
a(sub4) = 432
We set up a proportion: 63/?= 28/100
Cross multiply: 28*?= 63*100
⇒ ?= 63*100/28= 225
28% of 225 is 63.
Answer:
The correct answer is b.)
Step-by-step explanation:
Given:
Sequence -7, -4, -1, 2, 5....... => a₁ = -7, a₂ = -4, a₃ = -1, a₄ = 2 and a₅ = 5
We conclude that this sequence is arithmetic series.
First we must find difference d:
d = a₂ - a₁ = a₃ - a₂ = -4 - (-7) = -1 - (-4) = -4 + 7 = -1 + 4 = 3
d = 3
The formula for n-th term of the arithmetic series is:
aₙ = a₁ + (n-1) d
aₙ = -7 + (n-1) 3
God with you!!!
D. 50. Since WZ is perpendicular, it has a right angle plus the 40 degrees given at V equals 130. Add 50 to get 180.
