Answer:
-8 <_ x < -3
-7 <_ y < -2
Step-by-step explanation:
closed dot means it includes that number so in this case x is least than or equal to -8 and open dot means it doesn't include that value so x is less than -3 and does NOT include -3
and for the y value it's pretty self explanatory if u just count it (i might be off by a little cuz the photo quality is kinda fuzzy but i hope u get the gist!)
Answer:
4 2/9π or 4.22 (repeating)π
Step-by-step explanation:
<em>I changed my mind. I'll attempt it.</em>
The formula for finding the arc length: 
2π(4)(190/360) = 4 2/9π
82% certain the answer you're looking for is 4 2/9π (<em>pi symbol because it asks for it in terms of pi)</em>
Answer:
Actually it would be 87,100,000 in standard form.
Step-by-step explanation:
Check the picture below.
now, if AC is that much, recall, BD is the midsegment, thus AB = BC, so AB is just one of the equal halves of AC, so, AB is AC/2.
Hello,
A=(-4,2)
B=(3,-5)
AB≡y-2=(x+4)(-7)/7==>y=-x-2
Slope of the perpendicular: 1
y-2=(x-1)1==>y=x+1 is the equation of the perpendicular.
Intersection: y=x+1 and y=-x-2 ==>(-3/2,-1/2)=Q
|PQ|²=(-1/2-2)²+(1+3/2)²=25/2
|PQ|=5√2/2≈3.5355339059....
