Answer:
the equation in letter D is a linear function.
Answer: 
Step-by-step explanation:
Given the functions f(x) and g(x), to find 
you need to substitute 
into the function g(x):
Now, to find 
you must substitute 
into , then you get:
Answer:
So the answer is both
180 and 328 (but it may or may not show you "not possible, if so, then you got it right)
Step-by-step explanation:
SinA/a= SinB/b
1. SinM/780 = Sin164/760
2. 780sin164/760 = 0.2828909704
3. M = sin^-1 (0.2828909704)= 16.4328229 or 16
Check for possibility
180-16= 164
164 + 16= 180 (not possible)
164 + 164= 328 (not possible)
Answer:
1/5 = 9/45. 1/9 = 5/45. Hope this helps

Answer/Step-by-step Explanation:
==>Given:
Ratio of cost of 1m polyester fabric to 1m of cotton fabric = 2:7
I.e. if 1m of polyester fabric = £2, then 1m of cotton fabric = £7.
==>Required:
a. Cost of polyester fabric for the following lengths:
i) 6m ii) 8m iii) 9m
Thus, having known that cost of 1m polyester fabric = £2, therefore,
i) 6m polyester fabric = 6×2 = £12
ii) 8m polyester fabric = 8×2 = £16
iii) 9m polyester fabric = 9×2 = £18
b. Cost 8 cotton fabric for the following lengths:
i) 2m ii) 6m iii) 8m iv) 9m
Thus, since 1m of cotton fabric = £7, therefore,
i) 2m cotton fabric = 2×7 = £14
ii) 6m cotton fabric = 6×7 = £42
iii) 8m cotton fabric = 8×7 = £56
iv) 9m cotton fabric = 9×7 = £63
