Well Zack's cost more because, he paid $567.00 for whatever he bought, while Mal paid $245.00 for whatever he bought.
Answer:
not a function
Step-by-step explanation:
the vertical line test. if you can put a vertical line on the graph that goes through two points on the parrabola it is not a function
Answer:
6 hours
Step-by-step explanation:
If you add all of them together and estimated the answer than your estimation should be about 6 hours.
Answer:
- maximum current: 7
- time to reach maximum: 1
Step-by-step explanation:
The equation can be rewritten to vertex form to find the maximum value:
I = -5(t^2 -2t) +2 . . . . . . factor leading coefficient from variable terms
I = -5(t^2 -2t +1) +2 -(-5(1)) . . . . . add and subtract the square of half the t coefficient
I = -5(t -1)^2 +7 . . . . . . write in vertex form
The vertex of the graph is at (t, I) = (1, 7).
The maximum current of 7 is reached at t=1.
