Answer:
2
Step-by-step explanation:
the constant does change
33x - 38/x^2 - 3x + 1
Hope this helps
If you've started pre-calculus, then you know that the derivative of h(t)
is zero where h(t) is maximum.
The derivative is h'(t) = -32 t + 96 .
At the maximum ... h'(t) = 0
32 t = 96 sec
t = 3 sec .
___________________________________________
If you haven't had any calculus yet, then you don't know how to
take a derivative, and you don't know what it's good for anyway.
In that case, the question GIVES you the maximum height.
Just write it in place of h(t), then solve the quadratic equation
and find out what 't' must be at that height.
150 ft = -16 t² + 96 t + 6
Subtract 150ft from each side: -16t² + 96t - 144 = 0 .
Before you attack that, you can divide each side by -16,
making it a lot easier to handle:
t² - 6t + 9 = 0
I'm sure you can run with that equation now and solve it.
The solution is the time after launch when the object reaches 150 ft.
It's 3 seconds.
(Funny how the two widely different methods lead to the same answer.)
The answer is from AL2006
If were talking about the second one it would be 8 mins because by the time 6 is down to 2 it would be 8 mins and since 10 fl oz is going down every 1 min it would be 2 fl oz by the time it is at 8 mins
Answer:
D 18
Step-by-step explanation:
3z + 6
Let z=4
3*4 +6
Multiply first
12+6
Then add
18
