The diver will hit the water when the height is zero, so we will want to set our height function equal to zero
0 = -4t^2 + 11t + 3
we will then factor to find out value of t that make the function equal to zero
0 = (-4t - 1 ) ( t - 3 )
This means our function equals zero when t = -1/4 s and t = 3 seconds
Since time cannot be negative, our final solution is t = 3 seconds
James is weird , y would he want to know
Answer:
Step-by-step explanation:
The expression 
is a radical. To simplify pull out any perfect square factors.
Each of these expressions is equivalent.
45 / 18 as a mixed fraction...
To change the improper fraction to the mixed fraction you have to:-
first divide (as you divide) so that you can get remainder, quotient, divisor and dividend.
i.e 45 is dividend and 18 is divisor.
45 / 18 = 2 9 / 18 where 2 is quotient and 9 is remainder...
so the ans is 2 9 / 18
