The vertex of <span>y = 7x2 + 14x + 4</span> is at
(-1,-3) (see attachment)
Answer:
64
Step-by-step explanation:
As given, the diatance at any point after t seconds is given by
s(t)=16t²
At t=2 seconds then
s(2)=16*2²=16*4=64
Since we're not given the units, it may be feet, inches, meters, kilometers, miles etc. Therefore, the diatance is equal to 64 units
Answer: 76
Step-by-step explanation:
30 + 40 = 70
4 + 2 = 6
70 + 6 = 76

Answer:
hello your question is incomplete attached below is the complete question
answer : -2400 π
Step-by-step explanation:
dr/dt = -12 km/s
h = 2.5 km
r = 40 km at some instant
hence the rate of change of Volume of cylinder at that instance
= dv / dt =
= =
hence ; dv / dt = -2400 π
