1)B two real roots.
2)D two complex roots.
3) and 4) later
The hundreds place value would be 7
The turning point is at (2, 3)
F(-7) = -1.
An hour hand travels 30° every 60 minutes
30°/60=0.5° per minute.
Number of swings = x
Number of slides = y
First condition:
number of slides must be more than 3 times number of swings
This means that: y > 3x
Second condition:
each swing cost 275$ and each slide costs 168$. They cannot spend more than 1250$. This means that the sum of costs of swings and slides should not exceed 1250$ (should be less than or equal to 1250$)
This means that: <span>275x+168y ≤ 1250
Based on this:
The correct choices are: b and d</span>
