Answer:
100
Step-by-step explanation:
7 - (-93) = 100
-93 - (-193) = 100
-193 - (-293) = 100
As we can see, we get 100 for subtracting them all.
Best of Luck!
Hi there!
We can begin by simplifying cos(a + b) to find an equivalent expression.
With a sum of angles identity for cosine, we can determine that:
cos(a + b) = cos(a)cos(b) - sin(a)sin(b)
In this instance, we have to multiply this expression by csc(a)csc(b). Therefore:
(csc(a)csc(b)) · (cos(a)(cos(b) - sin(a)sin(b))
Distribute:
(csc(a)(csc(b))(cos(a)(cos(b)) - (csc(a)csc(b))(sin(a)sin(b))
Rewrite csc as 1/sin to simplify:
(1/sin(a) * 1/sin(b))(cos(a)(cos(b)) - (1/sin(a) * 1/sin(b))(sin(a)sin(b))
Multiply:
cos(a)/sin(a) * cos(b)/sin(b) - 1/sin(a) * sin(a) * 1/sin(b)*sin(b) <--- = 1
We now have remaining:
cos(a) / sin(a) * cos(b)/sin(b) - 1
Simplify to cotangent:
cot(a) * cot(b) - 1
Answer:
2m × <u> 100 </u> = <u> 200 </u>cm
Step-by-step explanation:
well the prefix <em>centi</em> means 100, and if you want to know how many <em>centi</em>meters are in a meter, then you should multiply by 100
so
2m × <u> 100 </u> = <u> 200 </u>cm.
Step-by-step explanation:
2/8 = 16/x
2x = 16×8
x = 16*8/2
x = 64.
Hope it helps :)
