0 = 55 k - 0.15 k^{2}

k = 0, k = \frac{1100}{3}

Decimal Notation

k = 0, k = 366.66666 \dots

Solution steps

0 = 55 k - 0.15 k^{2}

Multiply both sides by

100

0 = 5500 k - 15 k^{2}

Switch sides

5500 k - 15 k^{2} = 0

Write in the standard form

a x^{2} + b x + c = 0

- 15 k^{2} + 5500 k = 0

Solve with the quadratic formula

k_{1, 2} = \frac{- 5500 \pm 550 0 ^{2} - 4 ( - 15 ) \cdot 0}{2 ( - 15 )}

550 0^{2} - 4 (- 15) \cdot 0 = 5500

k_{1, 2} = \frac{- 5500 \pm 5500}{2 ( - 15 )}

Separate the solutions

k_{1} = \frac{- 5500 + 5500}{2 ( - 15 )}, k_{2} = \frac{- 5500 - 5500}{2 ( - 15 )}

k = \frac{- 5500 + 5500}{2 ( - 15 )} : 0

k = \frac{- 5500 - 5500}{2 ( - 15 )} : \frac{1100}{3}

The solutions to the quadratic equation are:

k = 0, k = \frac{1100}{3}

\frac{( y - 4 ) ^{2}}{4} = 7 - y

- - 68

4 x - 7 = 17

2 \leq \frac{3}{4} u + 8 \leq 11

7^{n + 2} + 7^{n}
