(19.-2).(-11, 10) find the slope
1 answer:
Answer:
Explanation:
The problem is: <em>given the points (19,−2) and (−11,10) find the slope of the line that joins them.</em>
The <em>slope </em>of a line is the change in the y-coordinate over the change of the x-coordinate:
- slope = rise / run = Δy / Δx
Thus:
Simplify, dividing both numerator and denominator by 6:

Answer:
Amount of input horsepower needed is 279.3 hp.
Step-by-step explanation:
if there is a loss of power of 5% the base horsepower will need to be increased by same percentage so that same amount of power can be delivered.
Now to calculate 5% of 266 hp, we can write
266 × = 13.3 hp
Now to deliver same amount of power we will have to add 5% of 266 hp to its actual power.
So real base power which is needed to deliver 266hp output even at a loss of 5% will be = (266+13.3) hp = 279.3 hp
