tangare [24]

Answer:

Since 64= 2^6, you have the following arrangements.

Optional: 64 \times 1 (and it's mirror version 1 \times 64, if you want to consider a long strip of bottles a rectangle. Technically it is, but it's open to interpretation.

32 \times 2 and it's mirror 2 \times 32;

16 \times 4 and it's mirror 4 \times 16;

Optional: 8 \times 8. Since a square is a rectangle with extra limitations.

Use the quadratic function f(x) = 2x^2 + 4x - 15. Find any x intercepts.
8_murik_8 [283]

So for this function we will be using the quadratic formula, which is x=\frac{-b+\sqrt{b^2-4ac}}{2a},\frac{-b-\sqrt{b^2-4ac}}{2a} , to solve. a = x^2 coefficient, b = x coefficient, and c = constant. Using our equation, we can solve for the zeros (x-intercepts) as such:

x=\frac{-4+\sqrt{4^2-4*2*(-15)}}{2*2},\frac{-4-\sqrt{4^2-4*2*(-15)}}{2*2}\\ \\ x=\frac{-4+\sqrt{16-(-120)}}{4},\frac{-4-\sqrt{16-(-120)}}{4}\\ \\ x=\frac{-4+\sqrt{136}}{4},\frac{-4-\sqrt{136}}{4}\\ \\ x=1.92,-3.92

In short, your x-intercepts (rounded to the hundredths) are (1.92,0) and (-3.92,0).
