Answer:

L1 and L2 are skew

Step-by-step explanation:

Since the equation of the line is

L1:x=9+6t,y=12-3t,z=3+9t

L2:x=4+16s, y=12-8s, z=16+20s

then if they intersect each other , they will have both in that point P=(xp , yp ,zp) then

1)9+6t = 4+16s

2) 12-3t =2-8s

3) 3+9t = 16+20s

adding 2*2) to 1)

9+6*t + 24-6t  = 4+16*s + 4-16*s

33 = 8

since this is not possible , the error comes from our assumption that the lines intersect each other

then they are skew or parallel. They are parallel if their corresponding vectors are parallel , that is

L1 (x,y,z) = (9,12,3) + (6,-3,9)*t

L1 (x,y,z) = (4,2,16) + (16,-8,20)*t

then if they are parallel

(16,-8,20)= k*(6,-3,9)

16=6*k

-8 = -3*k

20= 9*k

since there is no k that satisfy for x , y and z simultaneously then L1 and L2 are not parallel

therefore L1 and L2 are skew

Final answer:

The lines L1 and L2 are neither parallel nor intersecting. Upon comparing their direction vectors and attempting to find a common solution, it is determined that they are skew.

Explanation:

In order to determine whether two lines in three dimensions are parallel, skew, or intersecting, we compare their direction vectors. The given lines L1 and L2 are in the form of parametric equations. The direction vectors for the lines are d1 = <6, -3, 9> for L1 and d2 = <16, -8, 20> for L2. To determine if they are parallel, we check if there is a constant ratio between the corresponding terms. This isn't the case here, so the lines are not parallel.

For skew lines, they neither intersect or are parallel. Since we have already confirmed the lines are not parallel, to confirm if they are skew we must try to find a common solution (point of intersection). If we cannot, then they are skew. However, solving the equations does not give a common solution, so they do not intersect either. Hence, the lines are skew.

Answer:

Letter E represents the maximum of the data set on the box-plot.

Step-by-step explanation:

We now that in the given box-plot we have:

Letter A represents the minimum value of the data set.

Also in the given box of the whisker-box plot the lower value in the box represents the lower quartile or first quartile i.e. i.e. letter B.

Also, the middle value in the box-plot represents the middle quartile or median of the data i.e. i.e. letter C.

And the maximum value on the box represents the upper quartile i.e. i.e. letter D.

The maximum value of the data set is represented by letter E.

E is your correct answer cause that's the maximum range in that data there is no other range going past it.

Answer:

measure of the indicated angle

=180-(135+22)

=180-157

=23°

thefirstoptionistheanswer

Answer:

23

Step-by-step explanation:

135+22 = 157

all angles add up to 180 degrees so

180-157 is 23

The word phrase "sixteen times the sum of 10p and seventeen" can be translated into the following algebraic expression 16(10p + 17)

The word "sum" means that we add 10p and 17. The word "times" means that we multiply the sum by 16.

Therefore, the algebraic expression 16(10p + 17) represents the phrase "sixteen times the sum of 10p and seventeen".

Here is a step-by-step translation:

Break the phrase "sixteen times the sum of 10p and seventeen" into smaller parts.

Translate each part into an algebraic expression.

Combine the algebraic expressions into a single expression.

The translated expression is 16(10p + 17).
