Answer:
B. 1/(3xy^3)
Step-by-step explanation:
The minus sign can be dealt with first, then the root taken.
Answer:
repost it, I cant see all of the question
Answer:
Step-by-step explanation:
we know that
The circumference of a circle is equal to
In this problem we have
substitute
Remember that
subtends the arc length of the complete circle
so
by proportion
Find the measure of the central angle for an arc length of
3 possible solutions.
The reason is because of the degree, which is 3
Part (a)
<h3>Answer: y1 and y3 are perpendicular</h3>
This is because the two slopes 2 and -1/2 multiply to -1. Perpendicular slopes multiply to -1 assuming neither line is vertical or horizontal.
=====================================================
Part (b)
Graph each line to see where they cross. The three points of intersection are
(0,4)
(2,-2)
(4,2)
The order of the points doesn't matter.
You could also form three systems of equations pairing up the equations, and solving each system. That way you can find the points of intersection. Graphing may be a better and faster route in my opinion. See the diagram below.
