Answer:
L = 3√5
Step-by-step explanation:
A square and a rectangle have equal areas.
Area of a square = Area of a rectangle
L² = H * W
If the dimensions of the rectangle are 15 units by 3 units,
L² = 15 * 3
L² = 45
Determine the length of the side of the square.
L = √45
L = 3√5
0.25 = 1/4, 0.8 : 4 = 0.2
Answer:
= 9
Step-by-step explanation:
Note there is a common ratio r between consecutive terms of the sequence, that is
r = 18 ÷ 2 = 162 ÷ 18 = 1458 ÷ 162 = 13122 ÷ 1458 = 9
A recursive formula allows a term in the sequence to be found by multiplying the previous term by the common ratio, that is
= 9
with a₁ = 2
