Answer:
z=5
Step-by-step explanation:
A because it can’t be 100 and it can’t be 625 and it can’t be 50 so it has to be A
Answer:
Last Year Length = 4 meters
This Year Length = 12 meters
This Year Width = 10 meters
Step-by-step explanation:
We know, area of the rectangle is given by the formula:
Area = Length * Width
Given width = 5
Area = 20
We solve for Length:
Area = Length * Width
20 = Length * 5
Length = 20/5 = 4
Last Year Length = 4 meters
Now, this year, the length would be 3 times as long, so new length would be:
This Year Length = 4 * 3 = 12 meters
This year, the width would be two times previous year, so width would be:
This Year Width = 5 * 2 = 10 meters
Y = abˣ
(a ≠ 0, b ≠ 0)
(1, 7.5)
x = 1
y = 7.5
↓
7.5 = ab
(3, 16.875)
x = 3
y = 16.875
↓
16.875 = ab³
7.5 = ab
b b
7.5/b = a
16.875 = ab³
b³ b³
16.875/b³ = a
7.5/b = 16.875/b³
7.5/b(b³) = 16.875/b³(b³)
7.5b² = 16.875
7.5 7.5
b² = 2.25
√(b²) = √(2.25)
b = 1.5
a = 7.5/b
a = 7.5/1.5
a = 5
y = 5(1.5)ˣ
Answer:b
