Answer:
0
Negative
Un-defined
Things you need to know:
Any line parallel to the x axis is 0
any line parallel to the y axis is infinite/un-defined
Any line that is slanted in that way shown in the picture is negative vice versa the other way it is slanted will be positive.
B. -4.5
You need to isolate x by subtracting -4.1 and to keep the equation equal you need to do this on both sides.
Answer:
RS = 15 and RT = 18, then ST = 3! :D
Step-by-step explanation:r = 1 --> s=15 & t=18 so st = 270
r = 3 --> s = 5 & t = 6 so st = 30
r = 5 --> s = 3 & t = 3.6 so st = 10.8
etc
==============
In literal terms:
s = 15/r
t = 18/r
Step-by-step explanation:
Answer:
-1, 4
Step-by-step explanation:
We will get shaded area when we subtract rectangle area from semicircle area.
Rectangle area is Ar=a*b=16*6= 96 cm∧2
Semicircle area is Asc= (r∧2 pi)/2
First we must find radius.
We know that the center of the semicircle ( or circle) is in the middle of the longer side of the rectangle.
Now we can find radius with Pythagorean theorem
r= √8∧2+6∧2= √64+36 =√100= 10cm => r= 10 cm
Asc=(10∧2 * pi)/2 = 50 pi cm∧2
Shaded area is Asc - Ar = 50pi - 96 = 2 (25pi-48) cm∧2
Good luck!!!
