Answer:
t=(2.5,0)
Step-by-step explanation:
Given that
and
u=(-1,4)
v=(3,-2)
Then,substitute value of u and v in the equation
Answer:
210-20x=y
Step-by-step explanation:
150 is after 3 weeks of withdrawing 20 so $60
150+60=210 is the beginning amount
210-20x=y
Answer:
$92.33
Step-by-step explanation:
You take 143.75 and multiply by .3 to find the amount you will discount from 145.75, to get 102.025. Then multiply that by .095 to get 9.692375. Subtract that from 102.025 to get 92.33.
Answer:
I am not 100 percent sure, it's been a long time since I've done this type of math but I think that these are the answers
Step-by-step explanation:
1. x= -3, y=-3
2. x= 5, y= -2
3. x= -3, y = -7
4. x=2, y= 1
5. x=0, y= -4
F is conservative if we can find a scalar funciton <em>f</em> such that grad(<em>f</em>) = F.
This would entail
Integrate both sides of the first equation with respect to <em>x</em> :
Differentiate both sides with respect to <em>y</em> :
Differentiate both sides with respect to <em>z</em> :
So we have
that satisfies
and so F is indeed conservative.
