Answer:
See below in bold.
Step-by-step explanation:
(1) cosec ( x + 10) = 3
Now cosec x = 1/sin x so
1 / sin (x + 10) = 3
3 sin (x + 10) = 1
sin (x + 10) = 1/3
x + 10 = 19.47 , 160.53 degrees
x = 9.47, 150.53 degrees.
(ii) cot (x - 30) =0.45
cot (x - 30)= 1 /tan (x- 30) so we have
tan (x - 30) = 1 / 0.45 = 2.2222
x - 30 = 65.77 degrees
x = 95.77 degrees.
False
true
false
i could be wrong but i’m 85% certain
Domain represents the possible x values for the function.
It is...
x≤-2 and x>2
answer: a,b,c,f
Answer:
6.5
Step-by-step explanation:
first subtract 7 from both sides
2x=13
next divide both sides by 2
x=6.5
