Answer: I think it’s 225
Explanation: 1,500 • .15= 225
Answer:
585 miles
Step-by-step explanation:
Basically since he drove 715 miles in 11 hours you would have to divide the 2 numbers then you get 63.
63 is the rate so then you multiply by 9 hours then that's your miles.
585 miles
14×12=168
24×7=168
168÷60=2 hours and 48 minutes
2 hours and 48 minutes+ 8:00AM=10:48AM
Answer: 10:48AM
Answer:
A
Step-by-step explanation:
because if 8 is g that makes the top 8 and 2+3 eaquls five. this is simple
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.)
