Skew lines exist in a
three-dimensional geometry. These are lines that are not parallel with each
other but do not intersect. They are lines that do not lie on the same plane or
non-coplanar. Therefore, the correct answer is never. <span>If one line is skew to another, then they are never coplanar.</span>
If 12.5*(n)=32, then the value of (n) is 2.56, or rounded to the nearest tenth, 2.6.
To get that answer you’d divide 32 by 12.5
Answer:
x =11/4
Step-by-step explanation:
32(x−2)−5=19
Add 5 to each side
32(x−2)−5+4=19+5
32 (x-2) = 24
Distribute
32x -64 = 24
Add 64 to each side
32x-64+64 = 24+64
32x = 88
Divide by 32
32x/32 = 88/32
x = 88/32
Divide top and bottom by 8
x =11/4
The sum of the exterior angles is 360 deg. Each interior angle is supplementary to its corresponding exterior angle, so
So you have
We have that
x²+2xy+4y²<span>=12
we know that
</span>A better way to do this problem is using what is called “Implicit Differentiation
so
step 1
Differentiate both sides of the equation using the Chain Rule
x²+2xy+4y²=12-------> 2x+2y+2xy1+8yy1=0
2xy1+8yy1=-2x-2y--------> y1*[2x+8y]=-2x-2y
y1=(-2x-2y)/(2x+8y)
for the point (2,1)
y1=(-2*2-2*1)/(2*2+8*1)-------> y1=-6/12------> y1=-1/2
step 2
find the equation <span>of the tangent line with m=-1/2 and the point (2,1)
y-y0=m*(x-x0)------> </span>y-1=(-1/2)*(x-2)-----> y-1=(-1/2)x+1
y=(-1/2)x+2
the answer isy=(-1/2)x+2using a graph tool
