Hello,
(x²-1)(x²+2)(x+3)(x-4)(x+1)=0
==>(x+1)(x-1)(x-i√2)(x+i√2)(x+3)(x-4)(x+1)=0
Roots are -1 double, 1, i√2,-i√2,-3 and 4.
Answer:
Which problems ?
Step-by-step explanation:
This is exponential decay of the form:
f=ir^t, f=final value, i=initial value, r=rate, t=time in this case:
V(t)=408000((100-18)/100)^t
V(t)=408000(0.82)^t so
Vo=408000 and b=0.82
....
V(8)=408000(0.82)^8
V(8)=$83400.95 to nearest cent
Answer:
250
Step-by-step explanation:
1 meter = 100 centimeters
2.5 x 100 = 250
Answer:
Step-by-step explanation:
So we have the equation:
First, distribute the left side:
Add values on the left side:
Add 7 to both sides. The right side cancels:
Subtract 2x from both sides. The left side cancels:
Divide both sides by -6:
Therefore, x equals -3.
