Answer:
Option C. No solution is the right answer.
Step-by-step explanation:
Here the given equations are y = x²+2x+3 -----(1)
and y = 4x-2 -------(2)
Now we substitute the value of y from equation 2 into 1.
x²+2x+3 = 4x-2
x²+2x+3-2x = 4x-2-2x
x²+3 = 2x-2
x²+3-2x = 2x-2x-2
x²-2x+3 = -2
x²-2x+5 = 0
Then value of
Since in this solution √(-20) is not defined. Therefore there is no solution.
Answer:
It will leave the sprinkler at speed of
Step-by-step explanation:
We have given internal diameter of the garden hose
So radius
So area
Water in the hose has a speed of 4 ft/sec
So
Number of holes n = 36
Diameter of each hole
So radius
So area
