The four quadrants and the sign of coordinates is given as follows:
Quadrant I : (n, n ) both x and y positive.
Quadrant II : ( -n,n) = x negative and y positive.
Quadrant III : ( -n,-n) = both x and y negative.
Quadrant IV: (n, -n) = x positive and y negative.
So Based on the above concept , we can say that vertex C (-n,-n) has both x and y negative and so it lies in quadrant III.
Answer is Vertex C (-n,-n)
Answer:
Whether the student recycle the paper or not.
Step-by-step explanation:
We are given the following in the question:
Officials of a major university want to know what percent of their students recycle paper.
A random sample of sample size 200 is taken.
We have to find the variable that is measure on each student of the sample.
Variable of measurement on each student:
Whether the student recycle the paper or not.
The student will reply a yes or no as an answer.
Answer:
This can be solved like this:
4x-3x+9=20
<em>Solving 4x-3x</em>
x+9=20
Transposing +9
x=20-9
And now we have, x=11
Answer is c
use pythagorean
a^2 + b^2 = c^2
8^2+15^2= c^2
289=c^2
sqrt both sides
c=17
BC=17
