We have,
t = 6.21 s
s = 111 m
u = 0 m/s
To determine: "a" of the particle.
We know,
s = ut + ½ at²
⇒ s = ½ at²
⇒ a = 2s/t²
⇒ a = [2(111 m)]/(6.21 s)²
⇒ a = (222 m)/(38.5641 s²)
⇒ a ≈ 5.75 m/s²
Answer:
f(x) = 
Step-by-step explanation:
First of all, if 2 - i is a zero, then so is 2 + i
All you need to do now is multiply (x - 1)(x - 3)(x - 2 + i)(x - 2 - i)
I will do part of that multiplication
(x - 2 + i)(x - 2 - i) =
- 2x - xi - 2x + 4 + 2i + xi - 2i - 
=
- 4x + 5
So, now (x - 1)(x - 3)(
- 4x + 5) = 
I will let you finish that multiplication. I did some and you can do some. OK?
Answer:
$40 ; $43.20
Step-by-step explanation:
a) 50 * (1 - .20) = 50 * .8 = 40
b) 50 * (1 - .20) * (1 + .08) = 43.20
