Answer:
They show as intersections with the x-axis
Step-by-step explanation:
For example, the quadratic y = x² - 1 has roots x = -1 and x = 1.
They show on the graph as intersections of the parabola with the x axis at x = -1 and x = 1.
Answer: 6 + 4 + 3 - 6 - 0
Step-by-step explanation: Add 6, 4, and 3 which gives you 13. Then subtract 5 which gives you 8, then to use all the numbers, subtract 0. There's probably other ways but this is a very simple way.
Answer:
work output is always less than work input - the ratio is less than 1.
Step-by-step explanation:
This principle comes from the fact that a machine or system cannot produce more work than is supplied to it, because this would violate the energy conservation law (work is a type of mechanical energy).
In theoretical machines called "ideal machines" the input work is the same as the output work, but these machines are only theoretical because in real applications there is always some type of energy loss, either in heat produced by a machine or processes for its operation, for this reason the output work is always less than the input work.
Regarding the ratio work output to work input:
WO/WI<1
because work input WI is always greater than work output WO.
Answers:
1.) 1/9 m cubed
Explanation: The formula is l x w x h. So 1/3 x 1/2 x 2/3.
2.) 15/16 ft cubed
Explanation: 5/4 x 3/2 x 1/2.
