Answer: C) perpendicular</h3>
Explanation:
Each equation given to you is in y = mx+b form (aka slope intercept form).
The slope m is what we'll focus on.
The first equation has slope of 1, while the second equation has slope -1.
The two slopes multiply to -1. This is a property of any pair of perpendicular lines, as long as neither line is vertical nor horizontal.
Or you could note that -1 is the negative reciprocal of 1, or vice versa.
So there are a few options to see why the lines are perpendicular.
Answer:
<em>The surface area is multiplied by 4/9.</em>
Step-by-step explanation:
<u>Surface Area of a Cone</u>
Being r the radius and l the slant height of a cone, then its surface area is

Now let's think both the radius and the slant height are multiplied by the same factor k, i.e.
r'=kr
l'=kl
The new surface area is


The new surface area is the
times original SA. Since k=2/3, then

The surface area is multiplied by 4/9.

so namely, the "common difference" d = -4, and the first term a₁ = 7.
