Answer= c
In this case you've got to place the vector from the origin, so you have to get the difference from both points (x2-x1) and (y2-y1)
So you get that the vector from the origin is (18,-7)
Know you know the vector v is three times the vector u, so you multiply three times the vertex, but remember the vector v goes int he opposite direction, so the vector v from origin the the terminal point is (-54, 21)
P + 7 / 12 = 3
x12 x12
p + 7 = 36
-7 -7
p = 29
Answer: Plan A is cheaper, because the cost of a 2-minute call and a 4-minute call is less than the cost of a 2-minute call and a 4-minute of Plan B call.
Step-by-step explanation:
1. You have the following information of Plan A:
- A 2 minute call costs .54 cents.
- A 4 minutes call costs $1.08.
2. For Plan B, you know that the cost of is given by the equation:
3. Therefore, you can compare both plans by finding the cost of a call of 2 minutes and a call of 4 minutes of Plan B. You can calculate this by giving these values to :
4. Substitute the values into the equation:
(This is more expensive)
(This is more expensive)
5. Therefore, Plan A is cheaper, because the cost of a 2-minute call and a 4-minute call is less than the cost of a 2-minute call and a 4-minute of Plan B call.
Answer:
1/2
Step-by-step explanation:
First, find the recipocal (or however you spell it):
2/3 = 3/2
Next, multiply:
1/3 x 3/2 = 3/6
Simplify:
3/3=1
6/3 = 2
Final product:
1/2
