Ques 1)

Birch and Oak

Ques 2)

Birch and Maple.

Step-by-step explanation:

Ques 1)

Clearly from the figure attached we could observe that street Oak and Birch intersect each other but are not perpendicular as street Oak is slanting and is not horizontal to make a 90 degree angle with the vertically straight street Birch.

Hence, two streets that intersect but do not appear to be perpendicular are:

Birch and Oak.

Ques 2)

From the figure we could see that the streets Maple and Birch both are vertically straight and also do not intersect.

hence, those two are parallel as they are at the same distance from each other.

Hence, two streets that appear to be parallel to each other are:

Maple and Birch.

the value of v.w= -12.

step-by-step explanation:

we are given three vector r,v and w as:

r = < 5, -5, -2> ; v = < 2, -8, -8> ; w = < -2, 6, -5>

we know that r,v and w could also be represented as:

r=5i-5j-2k

v=2i-8j-8k

and w= -2i+6j-5k

where i,j and k are the unit vectors of x,y and z-axis respectively.

also we know that it has the following property:

i.i=1 ; j.j=1; k.k=1

and i.=j.i=i.k=k.i=j.k=k.j=0

i.e. when we multiply two vectors or we find it's dot product we need to only multiply the components of x coordinates with each other; y with each other and z with each other.

hence, v.w= (2i-8j- -2i+6j-5k)

                  = 2×(-2)+(-8)×(6)+(-8)×(-5)

                  = -4-48+40

                  = -12

hence, v.w= -12

$9.89

step-by-step explanation:

9.90 = p x .06 x .25 (3/12 changed to a decimal)

9.90 = p x 0.015

9.90 - 0.015 = p

9.89 = p
