Answer : number 4 is a dependent system
Explanation:
If we look at number 4
2x+2y=6 , y= -x+3
2(x+y)=6
x+y=6/2=3
y=-x+3
Now we see that the two equation have the same slope (-x) and the same y intercept (+3) we can clearly say that these 2 equation are dependent because it has infinite solution
Answer:
252 songs per 18 CD's
252/18 = 14
14 songs per CD
Step-by-step explanation:
The formula of a cylinder is 2πr (r+h)
2π4 (4+9)
8π (13)
25.13 (13)
326.73
Cubes: area = a^3
3x3x3 = 27
326.73 / 27 = 12.1
Claudia would need to buy 13 wax cubes to fil the candle.
hope this helps k12 students :)
Answer:
a) lim x ⇒0 eˣ - x - 1cos(x) -1 = -1
b ) q = √a/b
Step-by-step explanation:
a) lim x ⇒0 eˣ - x - 1cos(x) -1 ⇒ e⁰ -(0) - cos(0) -1 = 1-0-1-1 = -1
B) The weekly cost of the company is C(q) = a/q + bq
In cost equation the term a/q represent the ordering cost. In fact if q increase the ratio a/q decrece and the term bq represent the storage cost that will grow as the storage quantity increase
C(q) = a/q + bq Taking derivative C´(q) = -a/q² + b
-a/q² = -b ⇒ a/q² = b ⇒ q² = a/b ⇒ q = √a/b
