There are 10 guppies, so we do 25-10
Which equals to 15
Answer is 3/5
y = a(x - b)^2 + c has vertex (b , c)
so here the vertex is (1, -36)
Answer:
A unit rate is a rate where the second quantity is one unit , such as:
- $34 per pound
- 25 miles per hour
- 1 minute = 60 seconds
- 1 hour = 60 minutes
- Cost per litre.
Unit rate is used to compare quantities in which the second quantity is one.
39. because its close to it lol.
From calculus, to determine the maxima or minima of the graph, get the derivative of the equation and equate to zero. So, we derive first the equation of the graph and equate to zero.
C = 0.25x² - 80x + 30000
dC/dx = 0 = 0.5x - 80 + 0
0.5x = 80
x = 80/0.5
x = 160 units
The minimum cost (although not asked) is:
C = 0.25(160)² - 80(160) + 30000
C = $23,600
The answer is 160 units.
