Question

solve for t

50= -16T^2 +70T + 3

Answer 1

round your answer to the nearest hundredth

Answer 2

first you might want to simplify the quadratic equation by subtracting both sides by 50

then you can apply the quadratic formula to solve for t
\(\Large \begin{array}{*{20}c} {T= \frac{{ - \color{blue}{b} \pm \sqrt {\color{blue}{b}^2 - 4 \color{red}{a} \color{green}{c}} }}{{2\color{red}{a}}}} & {{\rm{when}}} & {\color{red}{a}T^2 + \color{blue}{b}T +\color{green}{c} = 0} \\ \end{array}\)

Answer 3

so just plug it in to the quadratic formula?

Answer 4

yes after you simplify the equation

Answer 5

you should have two solutions

Answer 6

okay

Answer 7

are you solving for it ?

Answer 8

yes

Answer 9

- 70 +- 70 sqrt 192 / 32
