Answer:
Takin LHS
cot²a . cos²a
cos²a/sin²a-cos²a
cos²a -cos²a.sin²a/sin²a
cos²a(1-sin²a)/sin²a
cot²a.cos²a LSH=RHS PROved
Answer:
-26 is your answer
Step-by-step explanation: 2³ first which = 8 then solve in the parenthesis and all inside parenthesis = -19 so now you have -19+9-4². Now, solve 4² which = 16 so now you have -19+9-16 then solve that and it should give you -26.
Hope this helped you!!!!
Let h = number of hours
100 + 15h = 75 + 17h solve for h
100 = 75 + 2h subtract 15h from both sides
25 = 2h subtract 75 from both sides
12.5 = h divide both sides by two
You would have to work 12 hours and 30 minutes for both companies to cost the same.
Answer:
B. 203.403
Step-by-step explanation:
2 times 100 = 200
3 times 1 = 3
4 times 1/10 = 0.4
3 times 1/1000 = 0.003
200 + 3 = 203
203 + 0.4 = 203.4
203.4 + 0.003 = 203.403
