Evans finishes 42 laps in 96,6 mins and Loza finished 38 laps in 102,6 mins
Evans. 96,6÷42= 2,30 mins
Loza . 102,6÷38= 2,70 mins
2,70 mins - 2,30 mins
= 40 secs and Evan is faster with 40secs in each lap.
Answer:
1,2 and 4 are conservatives
3 is not conservative
Step-by-step explanation:
We calculate the Curl F
Remember that:
Curl F = <
>
1. Curl F = <0,0,5-5> = <0,0,0>
The potential function f so that ∇f=F
f(x,y,z) = 
Then F is conservative
2. Curl F = < 0, 0 ,0>
The potential function f so that ∇f=F
f(x,y,z) = 
Then F is conservative
3. Curl F = <0 ,0, 10+3xsin(y) - (-cos(y))>
= <0 ,0 , 10 +3xsin(y) + cos(y)<
How the field's divergence is not zero the vector field is not conservative
4. Curl F = <0, 0, 0>
The potential function f so that ∇f=F
f(x,y,z) =
Then F is conservative
Answer- x=9.16 x signifies how much more money the student needs to add to the $20 to reach 350 in 12 months.
Explanation- divide both sides by 12, then subtract 20.
30,60,90
45,45,90
Pretty much all angles that add up to be 180
BCGF is a quadrilateral, angles sum to 360 degrees.
B+C+G+F=360
B and G are right angles, formed by a radius and a tangent.
90+C+90+F=360
C+F=180
C and F are supplementary.
2x + 146 + 4x + 238 = 180
6x + 384 = 180
6x = -204
x = -34
Answer: -34, second choice
