Year 3 = 2s
Year 2 = 3 + x
Year 1 = x
s = second year
x = first year
2s = 26
s = 13
The second year they made 13 million
13 - 3 = 10
x = 10
They made 10 million the first year.
Step-by-step explanation:
First, find the intersections.
4x = x³
0 = x³ − 4x
0 = x (x² − 4)
0 = x (x + 2) (x − 2)
x = -2, 0, 2
So we will consider two intervals: -2 ≤ x ≤ 0, and 0 ≤ x ≤ 2.
Pick a point within each interval and evaluate both functions at that point. Compare to see which function is greater.
At x = -1, y₁ = 4x = -4, and y₂ = x³ = -1. So y₂ > y₁.
At x = 1, y₁ = 4x = 4, and y₂ = x³ = 1. So y₁ > y₂.
So the integral would be:
∫₋₂⁰ (x³ − 4x) dx + ∫₀² (4x − x³) dx
Answer:
The width of the actual fence is 90ft
Step-by-step explanation:
If 2in = 10ft, you want to find the scale factor. To do this, you need to divide 10/2, so for every 5ft, it is 1in. Now, you would take how many inches you have and multiply it by 5. (in our case, 18in)
18 x 5 = 90.
So the actual fence length is 90ft.
