For example: if you chose to invite 10 people the skating rink would cost a total of $50 including the room fee
If you invite 10 people to the bowling alley you would spend $65 Including the room
The answer would be to choose the skating rink
Answer:
Good Luck!
Step-by-step explanation:
Integrate both sides with respect to <em>t</em> :
∫ d<em>y</em>/d<em>t</em> d<em>t</em> = ∫ -12<em>t</em> ² d<em>t</em>
<em>y(t)</em> = -4<em>t</em> ³ + <em>C</em>
Use the initial condition to solve for <em>C</em> :
5 = -4•0³+ <em>C</em>
<em>C</em> = 5
So
<em>y(t)</em> = -4<em>t</em> ³ + 5
and the answer is D.
Alternatively, you can directly apply the fundamental theorem of calculus:
