Answer:
a) max 12000 , min 0
b) no solution
c) pricing based on profit
Step-by-step explanation:
a) look at the parabola
b) there is more than one x (0)
c) the y intercepts represent his profit based on how much he priced the items at
Using the expression 5x + 23, the answers are as follows:
1. 5 is the coefficient.
2. 2 is the base
3. 3 is the exponent.
4. X is the variable.
If we translate the facts into location equations, xM=Mona's location, xL=Lina's location, then we get:
xM(t) = 300t
xL(t) = v*t - 1000
xM(10)=xL(10)
Where v is Lina's speed we have to find.
Plugging them all together gives:
300*10 = 10v - 1000
Which can be solved:
3000 + 1000 = 10v
4000 = 10v
v=400
Lina should skate at 400 feet per minute!
The correct answer is 2 inches
Answer: 8
