Answer:
plus or minus √10 / 4
Step-by-step explanation:
0=-16t^2 +10 becomes easier to solve if we rewrite it as 16t^2 = 10.
Then t^2 = 10/16 = 5/8, and t = plus or minus √(5/8), or
t = plus or minus (√5) / √8), or
t = plus or minus (√5)√8 √5*2√2
------------- = -------------------
8 8
or plus or minus √10 / 4
Hi,
f°g means : apply first g then f . so calculate "g" and then use result as "x" in f.
g°f means : you apply first f then g
so : f°g = 2(3x²-x) -5 = 6x²-2x- 5
To improve in math, you need practice. have a try with g°f :)
give the answer in comments, and I will tell you if you are correct.
good luck.
