Answer:
6x³ - 17x² + 11x - 2
Step-by-step explanation:
The cubic polynomial in general form is:
- ax³+bx²+cx+d = (x-x1)(x-x2)(x-x3)
zeroes are
then we can get the polynomial as:
- (x-2)(x-1/3)(x-1/2)=0
- (x-2)(3x-1)(2x-1)=0
- (3x²-x-6x+2)(2x-1)=0
- (3x²-7x+2)(2x-1)=0
- 6x³-3x²-14x²+7x+4x- 2=0
- 6x³ - 17x² + 11x - 2= 0
So the required polynomial is:
Answer:
The answer is just 1 and 3.
Step-by-step explanation:
To understand this problem, you must think of what whole numbers actually are.
Whole numbers consist of Positive integers and Zero.
Positive integers include 1, 2, 3, 4, 5, 6, ... etc
Zero is 0
The reason isn't a whole number is because that fraction doesn't reduce any further and does not yield a whole number.
Answer:
A
Step-by-step explanation:
A
They are proportional because as one goes up, so does the other.
Answer:
Vel_jet_r = (464.645 mph) North + (35.35 mph) East
||Vel_jet_r|| = 465.993 mph
Step-by-step explanation:
We need to decompose the velocity of the wind into a component that can be added (or subtracted from the velocity of the jet)
The velocity of the jet
500 mph North
Velocity of the wind
50 mph SouthEast = 50 cos(45) East + 50 sin (45) South
South = - North
Vel_ wind = 50 cos(45) mph East - 50 sin (45) mph North
Vel _wind = 35.35 mph East - 35.35 mph North
This means that the resulting velocity of the jet is equal to
Vel_jet_r = (500 mph - 35.35 mph) North + 35.35 mph East
Vel_jet_r = (464.645 mph) North + (35.35 mph) East
An the jet has a magnitude velocity of
||Vel_jet_r|| = sqrt ((464.645 mph)^2 + (35.35 mph)^2)
||Vel_jet_r|| = 465.993 mph
