Equation of curves


Both curves lie on S.
We have to find the equation of tangent plane at P(4,1,4).


Hence, t=0 and u then it satisfied the given point.
Substitute the values in the derivatives


The equation of tangent at point P(4,1,4) is given by




Answer:
(6 + 3/n) -8
Step-by-step explanation:
Answer:
<u>$33.25</u>
Step-by-step explanation:
Taking Eric's hours as a ratio to the total hours :
- 3.5 : 3.5 + 2
- 3.5 : 5.5
- 3.5 x 2 = : 5.5 x 2
- 7 : 11
Multiply the ratio into the amount paid :
- 52.25 x 7/11
- 4.75 x 7
- <u>$33.25</u>
<u></u>
Eric's share of the money is <u>$33.25</u>
