Answer:
c) Length = 12, width = 8 and height = 23.
Step-by-step explanation:
Let the length be x, then the width = x - 4 and the height = 2x - 1.
a) The polynomial is x(x - 4)(2x - 1)
b) x(x - 4)(2x - 1) = 2208
c) x(x - 4)(2x - 1) - 2280 = 0
2x^3 - 9x^2 + 4x - 2280 = 0
I'll use graphical software to find a solution for this. Its easily obtained online.
There is one real root and its x = 12.
So the dimensions of the box are L = 12, W = 8 and H = 23 inches.
Answer: -240 = -4π / 3, 60 = π / 3, 270 = 3π / 2, 945 = 21π / 4, -30 = -π / 60, 195 = 13π / 12
Step-by-step explanation:
The formula for converting <em>Degrees </em>into <em>Radians </em>is <em>Degrees </em>* (π / 180) = <em>Radians</em>.
For -240, we have -240 * (π / 180) = -240π / 180 and simplifying gives us -4π / 3
60: 60 * (π / 180) = 60π / 180 = π/3
270: 270 * (π / 180) = 270π / 180 = 3π / 2
945: 945 * (π / 180) = 945π / 180 = 21π / 4
-30: -30 * (π / 180) = -30π / 180 = π / 60
195: 195 * (π / 180) = 195π / 180 = 13π / 12
Answer:
4.62
Step-by-step explanation:
2 * 1.62= 3.24
new cost is $3.24 + 2 = 5.24
5.24 * .12 = .62 discount
5.24 - .62
4.62
