Question

PLEASE HELP! I can't solve this problem... I keep getting the wrong answer

find T

0 = 145Tsin20-16T^2+5

Answer 1

it's just a quadratic in T...
use the quadratic formula to solve the equation.

Answer 2

write in standard form: aT^2 + bT + c = 0

where
a = -16
b = 145sin20
c = 5

Answer 3

I did use the quadratic formula but I keep getting a wrong answer...that's why I sort of need a more descriptive answer...

Answer 4

with those values for a, b, c?
first calculate what b=...

Answer 5

0= -16T^2+49.592920T+5 O.O

Answer 6

i got 3.18 or -0.98
