Answer:
2/3
Step-by-step explanation:
now, that will give you "A", or the compounded amount
what's the interest earned? well, subtract the original amount, the Principal, from A, A - P, and you'd be left with the earned interest

1. The direction of the vector relative to the positive x-axis satisfies
2. A vector with magnitude and direction has component form
We have , but "angle of 60 degrees with the negative x-axis" is a bit ambiguous. I would take it to mean "60 degrees counterclockwise relative to the negative x-axis", so that the direction is . Then
But this doesn't match any of the options, so more likely it means the angle is 60 degrees clockwise relative to the negative x-axis, in which case and we'd get
3. Same as question 2, but now we're using notation. The vector has magnitude and its direction is . So the vector is
4. The velocity of the plane relative to the air, is 175 mph at 40 degrees above the positive x-axis. The velocity of the air relative to the ground, , is 35 mph at 60 degrees above the positive x-axis. We want to know the velocity of the plane relative to the ground, .
We use the relationship
Translating the known vectors into component form, we have
This vector has magnitude and direction
(or 43 degrees NE)
Answer:
x should equal 39 because 102+39=141 so subtract that from 180 like so. 180-141 which equal 39 the answer.
Answer:
(C)90 – 10y = 5x
Step-by-step explanation:
Given:
x = number of times she hiked the 5-mile trail
- Then, total Distance covered on the 5-mile trail =5x
y = number of times she hiked the 10-mile trail
- Then, total Distance covered on the 10-mile trail =10y
Maria hikes a total of 90 miles
Therefore, total distance hiked can be represented by the equation:
5x+10y=90
Subtract 10y from both sides, we have:
5x=90-10y
This is option C.
