Using a graphic tool.
<span>see attached graphic</span>
<span>
the solutions are
x1=-2
x2=0.811
</span>check
for x=-2
x^4+3x^3+3x2-3x-4
(-2) ^4+3(-2) ^3+3(-2) ^2-4=16+(-24)+12-4=0 ok
For x=0.811
(0.811) ^4+3(0.811) ^3+3(0.811) ^2-4=0.4326+(1.6002)+1.9731-4=0 ok
Answer:
64 handshakes
Step-by-step explanation:
SO i would do:
1 person x 8 handshakes
8x8=64
8 people 8 hand shakes each
Answer: C
Step-by-step explanation:
Since we are given velocity, which is the first derivative, we have to fidn the antiderivative of velocity to get position.
∫-2sint dt
s(t)=2cos(t)+C
Since we are given s(0)=0, we can plug in the values to find C, constant.
0=2cos(0)+C
0=2(1)+C
0=2+C
C=-2
Now that we know our constant, we can find out position.
s(t)=2cos(t)-2
