Answer:
7.6 ft² ( to 1 dec. place )
Step-by-step explanation:
given 2 sides of a triangle and the angle between them, the area (A) is calculated using the formula
A = ac sin B
= 0.5 × 4 × 13 × sin 17° ≈ 7.6
The cost of printing books C varies partly as the amount A charged by the printer
1 answer:
The equation connecting C,A and n is C = 25A -
Variation is a mathematical term used to show how a quantity behaves when one quantity increases or decreases.
Analysis:
C = AK + M/n
where K and M are constants
when n = 1000, A = 5000, C = 75010
75010 = 5000K + M/1000-----------1
50004 = 10000k + M/200-------------2
solving simultaneously, K = 25, M = -49990000
C = 25A - 49990000/n
In conclusion, the equation connecting C,A and n is C = 25A - 49990000/n
