0=40-10t-5t^2
t^2+2t-8=0
(t+4)(t-2)=0
t=-4 (not a solution) or t=2
Answer: after 2 seconds
Answer:
The antiderivative is 
.
Step-by-step explanation:
Antiderivative F(x)
This is the integral of 
So
F′(x) = f(x) = 6 + 24x^3 + 18x^5
Then:
F(1)=0
when 
. We use this to find K.
Thus
The antiderivative is .
Answer:
The formula to get the area of a circle is: A = πr²
5/8=0.625
7/12=0.583......
5/8 is bigger as ive put both into a decimal as it is easier to tell
Answer:
It is the <em><u>second one</u></em>
Step-by-step explanation:
1st option does not include the number 2 from the equation above,
and 3 and 4, you do not have to divide anywhere in the equation, so those are no possibly correct.
