I think the domain is -1 and the range is 2. You may want to double check though.
Answer:
13.0
Step-by-step explanation:
sin(65°) × 14.3 would give u 12.9 then u round it to the 13
Lim x->1 (x^2+8x-2)
substitute x =1
= 1^2 +8(1)-2
= 1 +8 -2
= 7
So the limit = 7
You multiply 86 by 42.5 because each board is 42.5 and there are 86 boards.
