Answer:
The rock splashes down when h(t) = 0. Set h(t) = 0 and solve for t using quadratic formula.
0 = − 4.9t^2 + 178t + 325

Step-by-step explanation:
this helped me in middle school so please remember this equation
A=P(1+R/N)NT
A=AMOUNT
P=PRINCIPAL

NT=TIME(YEARS
So now we have this... right...
A=P(1+R/N)NT
you have to fill it in and you will get
a=22,150(1+3/1)^2
put that in your handy dandy calculator and you will get your answer
B. (k+10f)(k-5f) you can tell in 2 ways. 1. if the second sign is neg then the signs in the factors are going to be one neg and one positive so that knocks out C and D. Then you look at the second term and since the 5 is positive then the 10 has to be positive so you end up with a positive 5kf.
The second way is to FOIL them out. When you check B you get
combine your like terms and you have your original expression of
