Answer:
B. a ⊥ d
Step-by-step explanation:
If lines "a" and "d" are in the same plane, they are perpendicular to each other. If not, there is no relationship between the lines.
__
Lines parallel to the same line are parallel to each other, so a║c. <em>In the same plane</em>, a line perpendicular to one of two parallel lines is also perpendicular to the other. (For example, one side of a rectangle is perpendicular to both of the adjacent sides, which are parallel to each other.)
The appropriate choice is ...
a ⊥ d
__
<em>In 3 dimensions, ...</em>
Consider a cube. A given edge will be perpendicular to both of the two edges it meets at a corner.
It will not intersect (has no "perpendicular" relationship to) either of the edges parallel to those that meet at the corner at the other end of the space diagonal.
Reasonable because the three items altogether cost about $40
Answer:
<h3>
B(1, -1)</h3>
Step-by-step explanation:
If M(-1, 4) is midpoint of AB then:
4(2)^4 - 2(7^2) + 40
4(16)-2(49)+40
64 - 98 + 40
-34 + 40
= 6

Explanation:</h2>
In this exercise, we have two cases and both will be polynomial functions with degree 3 because we have three real roots in each case. So:
<h3>First.</h3>
The roots are:
So we can write this polynomial functions as the product of linear factors:
Since we have to write it in standard form, let's expand:
<h3>Second.</h3>
The roots are:
Writing the polynomial function as the product of linear factors:
