Answer:
t=1.58 seconds
Explanation:
The equation which models the height <em>h</em><em> </em>of the seashell above water after t seconds
Ifthe roots are r1 and r2
then the factored form is
a(x-r1)(x-r2)
so
and multpilcty is how many times the root repeats
P(x)=(x-0)^4(x-2)^3(x-(-1))^2
so the roots are 0 multipilcty 4, 2 mupliticty 3, -1 multplity 2
Answer:B
Step-by-step explanation:
B because 3s opposite is -3
Answer: Number of sand bags are 105
Step-by-step explanation:
Alright, lets get started.
The diameter of pool is given as : 
The radius of pool will be : 
So the area of the pool will be:
Area = 
Area = 
Area = 
Area = 
3 square feet is covered by 1 sand bag, so
314.16 square feet will be covered by : 
So, no of sand bag = 
Rounding off to nearest number
Number of sand bags are 105 : Answer
Hope it will help :)
