The measure of segment PQ with P (-4.-9) and Q (4 -3) is 10 units.
<h3>How to find the length of a Line segment?</h3>
The formula for the length of the line segment is;
d = √[(x2 − x1)² + (y2 − y1)²]
We are given the coordinates of Line segment PQ as;
P (-4.-9) and Q (4 -3)
Thus, distance of line segment PQ is;
d = √[(4 − (-4))² + (-3 − (-9))²]
d = √(64 + 36)
d = √100
d = 10
Thus, we can say that the measure of segment PQ with P (-4.-9) and Q (4 -3) is 10 units.

Answer:
b. 
Step-by-step explanation:
The graph can be divided into 4 regions.
Region 1 is for 
Region 2 is for 
Region 3 is for 
Region 4 is for 
So, for the region 1, the values of 
goes on decreasing with increasing 
. Therefore, the function is decreasing in the interval 
.
Now, for the region 2, the values of increases with increasing . So, the function is increasing in the interval 
.
For the region 3, the the values of goes on decreasing with increasing . Therefore, the function is decreasing in the interval 
.
Now, for the region 4, the values of increases with increasing . So, the function is increasing in the interval 
.
Therefore, regions 2 and 4 are the regions when the function is increasing.
Hence, the correct option is b.
Answer:
by hand because hand solution can be done by mind and can be written in copy but in calculator to solve one problem the first should delete but in copy we can write and remember.
A.
A-triangle may have only one right or only one obtuse, may have two or three acute angles but never just one
because a triangle has three angles the m= 180, the other twp angles have to be acute
Hope this helps
