Answer:
4,-3
Step-by-step explanation:
Answer:
D.) an = 4 * an-1
Step-by-step explanation:
a(n) = (1/3) * 4^(n-1)
a(n-1) = (1/3) * 4^(n-1-1) = (1/3) * 4^(n-2)
Thus,
a(n) = (1/3) * 4 * 4^(n-2) = 4 * [(1/3) * 4^(n-2)] = 4 * a(n-1), so that
a(n) = 4 * a(n-1).
Answer:
Step-by-step explanation:
Given:
Base length:
A = 8.5 m
B = 4 m
Height, h = 2 ft
1 gallon = 350 ft^2
Area of trapezoid = 1/2 × (A + B) × h
= 1/2 × (8.5 + 4) × 2
= 12.5 ft^2
1 gallon = 350 ft^2
2 gallons = 700 ft^2
1 podium = 12.5 ft^2
= 700/12.5 podium
= 56 podiums will be painted with 2 gallons of paint.

Answer:
63.6mm
Step-by-step explanation:
According to cosine rule;
AB² = BC²+AC²-2(BC)(AC)cos m<C
Substitute the given values
AB² = 70²+40²-2(70)(40)cos 64
AB² = 4900+1600-5600cos64
AB² = 6500-5600(0.4384)
AB² = 6500-2,454.87
AB² = 4,045.12
AB = √4,045.12
AB = 63.6mm
Hence the length of AB is 63.6mm
